Literary Record.

The Royal Library at Berlin is said to contain six hundred thousand volumes. The books are not contained in one hall, but in an extensive suite of rooms. These rooms are filled with racks for the books, and the general subject is placed in conspicuous letters at the top of every case of shelves. Books of all languages are thus brought into the closest contact, and the scholar of a particular science has but to resort to that part of the library where his favorite branch is represented, and he is certain to find the best works, in whatever language published. Among the curiosities of the library are a collection of manuscript writings from some of the most distinguished men whom Germany has produced, from Goethe, Leibnitz, Frederick the Great, Klopstock, Lessing, Wilhelm von Humboldt, Frederick Schlegel, and a few others. There are three specimens from Goethe's pen, very indistinct, but yet written, apparently, with some care. Corrections were frequent; in one place the word had been twice corrected. Frederick, apparently, wrote in great haste; the signature, however, was more carefully executed. Humboldt wrote a fine, neat hand, perfectly free from blots and without corrections. Lessing's was much the same, but corrected in many places. Klopstock wrote with a trembling hand, and his manuscript is read with great difficulty.

In another case are curiosities of a very different nature. Here are the Bible and the prayer-book of Charles the First; the former was placed to his lips at the moment before his execution. How it came into the possession of the Prussian government is not stated. The Bible is of very unpretending appearance, but the prayer-book is very beautifully bound-its cover is of tortoise-shell, secured by massive gold clasps. Luther's Hebrew Bible, and his own German translation, are here too, and close by a sheet from the reformer's pen. The writing is bold and free. In the next case, to make a strong contrast, is one of Tetzel's famous indulgences, and a letter from that great man, Ignatius Loyola, the founder of the Order of Jesus. Other objects of interest are Zwingli's Bible, a specimen of Melancthon's hand-writing, a very old copy of the Koran, and a beautiful series of portraits of the leading reformers, from the pencil of Louis Cranach. For Luther's own copy of the Old Testament the English government has offered $100,000.

Honorary Degrees.-The crop of doctors, both of Laws and of Divinity, has not been so large this season as usual. At some colleges we perceive they have been under the necessity of doctoring men already doctored. We append a

list of such as have come to our notice :

Harvard University conferred the degree of D. D. upon Rev. J. H. Jones, of Philadelphia; Rev. Baron Stow, of Boston; Rev. George Ware Briggs, of Salem; Rev. Edward Cook, President of Lawrence University in Appleton, Wisconsin; Rev. Chandler Robbins, of Boston; Rev. Samuel Osgood, of New-York. Of LL. D. on his Excellency Henry J.

Boswell, of the Methodist Episcopal Church, South. At the same time the degree of LL. D. was conferred on the Honorable John S. Brien, of Nashville.-At Oglethorpe University, the degree of D. D. was conferred upon the Rev. Sylvester Woodbridge, of NewOrleans, and the degree of LL. D. upon the Rev. J. H. Thornwell, D. D., President of the South Carolina College.- At Trinity College, Hartford, the degree of D. D. was conferred on Rev.

D.--At Lafayette College, the degree of D. D. was conferred on the Rev. William Blackwood, of Philadelphia, and that of LL. D. on David Codwise, Esq., of New York City.

The Michigan Senator.-Mr. Derby has made arrangements for the publication, by subscrip tion, of the "Life and Times of General Cass," to be issued in one large volume of eight hundred pages, uniform in style and manner to "Benton's Thirty Years in the Senate." The volume is compiled by W. L. G. Smith, Esq., and will be published under the revision and superintendence of General Cass himself.

Silvio Pellico. - An Italian periodical, the Civilta Cattolica, announces that it is about to publish several manuscripts left by the late Silvio Pellico, and that they consist of correspondence, of moral, political, and religious treatises, of historical romances, of tragedies and poems. The romances, it appears, are not terminated; one, called Raffaella, was given up by its distinguished author because he had the modesty to think it inferior to the Promessi Sposi of Manzoni. The Civilta says that, in compliance with the solicitation of his friends, Silvio Pellico wrote his autobiography; but though, in the opinion of people who were allowed to read it, it possessed the highest interest, he, after the revolutionary movements of 1848, announced that he had destroyed it, and it has not been seen since. It is nevertheless hinted that a copy of it may some day sec the light.

Mr. Bailey, the author of Festus, has a poem in press entitled "The Mystic," which is described as wilder in imagery and purpose than "Festus;" dealing with higher and more mysterious arguments, and having in it still less of human sympathy and human emotion. Another poem, lyrical in form, is to accompany "The Mystic."

in the following order :-Reference books, poetry and romance; history and biography; politics; theology and philosophy; law; diplomatic and congressional; agriculture and science, and miscellaneous. These are all in the mansion library room and the law office. There are twelve hundred law and congressional books in the old Winslow House awaiting better accombook in the whole library.

The Univers publishes a sonnet to the Virgin, modation. There is not to be found a useless composed by General Vergé, who, it appears, made a vow at the moment when he was leading his brigade to the assault of the Mamelon Vert, that if he escaped death that day he would openly acknowledge the dogma of the Immaculate Conception.

In a recent sitting of the Academy of Inscriptions et Belles Lettres, at Paris, an account was given of the discovery at Beyrout, at a great depth under ground, of the tomb of a Phoenician king, containing-what is very curious indeed -a long inscription in Hebrew. The inscription dwells principally on the nothingness of human grandeur, and concludes by vowing to the wrath of Astarte any one who shall profane the tomb. A detailed account of the curious discovery is to be given to the French Institute by the Duke de Luynes, on the approaching annual meeting.

Biblical Literature.-To the library of Biblical Commentaries we have to add one just published in London, The Epistles of St. Paul to the Thessalonians, Galatians, and Romans, by B. Jewett, M. A. The work contains a body of text, and laying open the entire history of the philosophical criticism, based on Lachmann's apostolic doctrine, as well as tracing the varieties of interpretation, from the Textus Receptus, which Mr. Jewett discards, through the other existing manuscripts, which he examines.

Professor Longfellow is revising two volumes of new poems; both will probably be published before the year is out. One is a collection of lyrics; the other is a narrative poem, based upon Indian legends. The hero is said to be a kind of American Prometheus.

A curious collection of books is advertised for sale at St. Petersburgh. It consists of several thousand volumes exclusively relative to Turkey, and cost not only vast sums, but thirtyseven years' labor to form. It is the property of M. Liprandi, Councillor of State, brother of one of the Russian generals, whose name is frequently before the public as a commander in

Thackeray, we learn, is engaged by the NewYork Mercantile Library Association for a course of lectures during the coming winter. The subject is stated as "Men of the World." Another Methodist College.-The Pittsburgh Conference, at its late session, approved of a plan to locate a new college at Barnsville, Ohio. Its endowment of $100,000 is to be raised by the sale of perpetual scholarships. The "Richmond" College has also been placed lately in this city bearing several valuable do

under Methodist patronage and control.

The Lecture Season.-A convention of delegates from the literary associations of this state was held at Syracuse last month, at which a union was formed for the delivery of lectures on a systematic plan. The state is to be divided into six districts, and a member of a central committee to be appointed to each district, who will procure information concerning the number of lectures desired, the prices paid, &c., within his district. The president is to communicate with lecturers, and carry out the plans of the committee so far as possible.

Many of our readers are acquainted with the Mémoires de la Marquise de Crecy, which, published in French and translated into English, excited great sensation some time ago, and which even now are not unfrequently referred to as possessed of authority. A publication which has just been made in France proves them to be entirely false. This, indeed, was already known to people who occupy themselves specially with French literature.

Daniel Webster's Library.-The number of volumes in Mr. Webster's library is six thousand. Of these, two thousand are political, congressional, and diplomatic; one thousand historical; five hundred dictionaries, cyclopædias, and hand-books; five hundred works on agriculture, and a great number of maps and guide-books. The library is arranged in cases

the Crimea.

Literary Relics.-Mr. H. G. Somerby arrived

nations from George Peabody, the American banker in London, for the Peabody Institute at Danvers, Mass. They consisted of a volume of autograph letters from Washington, Franklin, Jefferson, Jay, Henry Laurens, Robert Morris, General Schuyler, Robert Livingston, John Quincy Adams, and other eminent Americans.

New Works.-Messrs. Longman and Co., of London, announce for publication the third and fourth volumes of Macaulay's "History of England;" "A Portion of the Journal kept by Thomas Raikes, Esq.," comprising Social and Political Life in London and Paris during the period 1831-1847; "A View of the Brazils, seen through a Naval Glass by Edward Wilberforce;""Eight Years' Wanderings in Ceylon," by S. W. Baker, Esq.; "The Dead Sea, a New Route to India," by Captain Allen, R. N., F. R. S. ; the third and fourth volumes of James Montgomery's "Life and Writings," and the third and fourth volumes of James Silk Buckingham's "Autobiography." Two more volumes are also announced of "Moore's Memoirs."

A pension of $250 a year, from the Civil List of Great Britain, has been granted to Dr. Dick, the author of some excellent works on

Christian Philosophy. "We only regret," says the Atheneum, "that a larger sum was not at disposal for the recognition of the literary services of so estimable a man and useful a writer."

"A Last Word on Sir Hudson Lowe," by Barthelemy Baron de les Cases, is the title of a new work recently published in Paris, and which is now exciting no little attention. In reviewing it the Athenæum says:

"It was once dangerous for a person of the name of Lowe to travel in France. St. Helena is said to have been avenged on Sir Hoodson Lor many a time and oft after that hard and rude janitor slept with his fathers. In the present instance, Mr. Forsyth's justifleatory publication is condemned as a long, dreary, and fastidious diatribe, and the Revue des Deux Mondes is lectured for having dragged it from its oblivion.' The baron adopts, with additions, the view taken by all reasonable men of Sir Hudson Lowe's conduct toward Napoleon. Without resuming the discussion, we may say that his criticism, though a little violent, is precise, and goes to the bottom of the subject: at the same time, we are glad that it is to be 'the last word' on this bitter topic."

Dr. Flügel, Professor of English Literature at the University of Leipsic, died recently in that city at an advanced age. He compiled an excellent German-English and English-German dictionary, and superintended many translations from our language.

The Bible in Turkey.-The demand for the Word of God in Turkey has obliged the British and Foreign Bible Society to make arrangements for the printing and publishing of Bibles and Commentaries on an extensive scale in Constantinople. This speaks well for the future. A correspondent, writing to the monthly paper of the Society, says:

"It is a remarkable fact that years ago our Society possessed only an obscure depot in Galata, which was opened only twice a week, and where the Turks never put their foot in, and the Christians entered it rarely and by stealth. Now, besides the great depot, which is kept open all day long in a most frequented street in Constantinople, leading to the principal bazaars, the Society's books are exposed for sale in the grand street

of Pera, at the Scripture Readers' Depository and Reading-room at Galata, at the London Jews' Society's stores at Constantinople; and last, not least, they are hawked about the streets of this vast capital by colporteurs, and may be met with on the great floating bridge, and other parts of the city, taken there by venders of books."

There is a talk of establishing in Paris a large daily newspaper, to be devoted entirely to literary, scientific, and artistic matters. The well-known Dr. Veron is named as the chief promoter of the scheme.

Mr. Vincent Figgins, a well-known English type-founder, has reproduced, for the benefit of the Aged Printers' Asylum, in England, in black letter, cast by himself, and imitated from Caxton's type, the first printer's treatise on the "Game and Playe of the Chesse." A writer in the London Athenæum, who seems charmed with both Caxton and Figgins, says:—

Mr.

"Of this work, Caxton printed two editions-one with the date 1474, and the other without a date, but ornamented with various quaint and rude, but forcible illustrative wood-cuts, the general character of which was imitated in Dibdin's imperfect fac-similes. Figgins has engraved all the wood-cuts completely from tracings made from the copy of the book in the British Museum. He has also printed his edition on paper made expressly in imitation of that used by Caxton, and has bound it in antique style, with appropriate ornamental tooling. The result of all this care and imitative skill is a handsome volume, in small

folio, published at the price of $10. The purchasers will not only have the satisfaction of possessing a work which is curious in itself, and gives a very accurate idea of Caxton's books, such as they first issued from the press, but will have the pleasure of contributing to a praiseworthy and excellent object. All who benefit by printing-and, in some way or other, who does not?-should bear in mind the band of skillful and useful men who, in connexion with this Art of Arts, bestow an almost unparalleled amount of labor and ingenuity, but who cannot, any more than other men, secure themselves from the unavoidable chances and occasional calamities of life."

The American Association for the advancement of Science recently held its ninth annual meeting at Providence, Rhode Island. The objects of the Association are to promote intercourse between those who are cultivating science in different parts of the United States; to give a stronger and more general impulse and a more systematic direction to scientific research in our country; and to procure for the labors of scientific men increased facilities and a wider usefulness. The Association at this time embraces more than a thousand members, consisting not only of those who are actually engaged in scientific pursuits, but of others who are the

patrons and friends of science, who appreciate its importance, and are anxious to aid its

progress.

Photographs.-Mr. Neipce's process of obtaining positive photographs is to expose a sheet of calotype paper to the daylight for a few seconds, or until a visible discoloration or browning of its surface takes place. Then it is dipped in a solution of iodide of potassium, consisting of five hundred grains to the pint of

Sciences.

water. The visible discoloration is apparently removed by this immersion-though such is no really the case, for, if the paper were dipped inte a solution of gallo-nitrate of silver, it would speedily blacken all over. When the paper is removed from the iodide of potassium, it is washed in water and then dried with blottingpaper. It is then placed in the camera obscura, and after five or ten minutes it is removed therefrom and washed with gallo-nitrate of silver, and warmed.

Useful Invention.-According to the London Times, a Mr. Clifford has invented a method of

lowering ships' boats, so as to insure entire security from accident. The whole operation is performed by one man only in the boat, who, by simply paying off a rope, unlashes and frees the boat from the ship's gripes, lowers her levelly into the water, and entirely disengages her, whatever her weight or the number of her crew; and it is impossible for her to cant or turn over in her descent, or for a rope to tangle or catch in its passage through the block which he uses.

ARTS AND SCIENCES.

A Female Painter.-Rosa Bonheur, who is pronounced by the London News the greatest painter of rustic subjects in France, is exhibiting some of her pictures in London. Of one of Horse Fair at Paris," the these, called the News says:

66

"In saying deliberately that we believe that no picture of modern times is more worthy than this of study, either by the artist or by the lover of nature, we shall be considered, perhaps, guilty of a little exaggerated enthusiasm. It may be so. Nevertheless, we have the best reasons for knowing that a large number of the most distinguished British artists hold the same opinion as ourselves. Let the picture, however, be judged by its merits. First, let the mere lover of nature, the man who has deep sympathies with all the healthy phenomena of animal life, look at the 'Horse Fair, and say if any mere representation of animals, whether by Wouvermans, or Cuyp, or Snyders, or Cooper, or Ward, or-we scarcely dare to sayby Landseer himself, has anything approaching to that exuberance of vitality which manifests itself in this astonishing delineation."

A Curious Clock.-An English paper says: The public does not generally know that at the Southeastern London Bridge Station, over the little refreshment-room facing the railway, stands a clock, whose pendulum is some five miles off; that is, at the Royal Observatory, Greenwich. It was made a present to the company by the government for permission to lay down its telegraph wires over their line, and is kept going by the wires of the telegraph attached to the clock of the Observatory. It is curious to observe the assumption of positive dignity with which the seconds' hand of the clock beats its time, as if conscious of its royal

and learned source of motion.

Portable Stove.-A new portable stove is described in the London Mining Journal. It is made of thin wrought iron, without any flue, and may be used upon any table or in any room. The fuel employed is cocoa-nut stearine, in cakes, burnt by means of six wicks introduced into each cake, the cake fitting into a tin dish, made exactly to contain it. No smoke is produced, and the stove is capable of boiling, baking, and broiling, and the whole is comprised The cost of in a cube of about sixteen inches.

fuel burnt is at the rate of one penny per hour, a cake lasting eight hours.

To make Artificial Marble and Stone.-The Scientific American gives the following condensed specification of a patent for the above purpose, "The material granted to an American citizen. of which the artificial stone is made is plaster of Paris. After it has been prepared and of the right shape, it is dried in a room at about 80 degrees. When completely dry, it is immersed in a warm solution of borax and glauber salts, prepared by dissolving one pound of borax and a quarter of an ounce of the salts in one gallon of water as a ratio.

After the casting is thoroughly wet in this, it is removed to the drying-room and exposed to a heat of 250 degrees Fahrenheit, until all the watery parts are thrown off. It is then permitted to get nearly cold, when it is immersed in a strong hot solution of borax, to which has been added one ounce of strong nitric acid for every gallon of the borax solution. This solution is kept warm, and the castings kept in it until they are completely saturated, when they are taken out and dried, and are found to have acquired

a marble-like hardness. A day or two after
this operation the castings are slightly heated,
and covered over with a thin coat of Canada
balsam dissolved in turpentine, after which they
are kept warm until the turpentine is driven
off. Various colored substances may be used
along with the materials specified to color the
artificial marble, such as indigo for blue, and
other substances for other colors. The marble
may also be streaked and beautifully vari-
egated."

A large picture by Raphael, inscribed with his name, and painted when he was only seventeen, is one of the chief celebrities on exhibition in London. It came from the Fesch collection, and was originally done for the Church at Città di Castello. The date attributed to it by Passavant is 1500. It displays the full influence of Pietro Perugino, and is, moreover, remarkable as the only representation by Raphael of the crucifixion. The angels balancing in the air, and the turn of the heads of the Madonna and St. John toward the spectator, contrast strongly with earlier representations of the subject, where the attention of every personage is absorbed by the central figure.

A machine for sowing seed broadcast, instead A series of of in drills, has been invented.

underneath the hopper, in combination with oblique cups are placed upon a rotating cylinder the hopper in such a manner that it is sprinkled distributing plates, which convey the seed from with perfect regularity and evenness over the whole ground traversed by the machine.

A lithographed portrait of Molly, the second wife of the German poet Bürger, whom he has celebrated in so many of his finest and most passionate songs, has just been published at Göttingen. It has been drawn from the original painting in oil, which was offered by the to his "as his greatest treasure' dying poet omist at the University of Göttingen. physician, Dr. Wrisberg, the late famous anat

Coal a source of National Greatness.-During a brief sojourn of that eminent geologist, Hugh Miller, in England, he critically examined the carboniferous districts, especially the coalfields of central England, to which she has for so many years owed her flourishing trade. Its area, he remarks, "scarcely equals that of one of the Scottish lakes-thirty miles long and eight broad; yet how many steam-engines has it set in motion! How many railway trains has it propelled, and how many millions of tons of iron has it raised to the surface, smelted, and hammered! It has made Birmingham a great city And if one -the first iron depót of Europe. small field has done so much," he says, "what may we expect from those vast basins laid down by Lyell in the Geological Map of the United States? When glancing over the three huge coal-fields of the United States, each surrounded with its ring of old red sandstone, I called to mind the prophecy of Berkely, and thought I could at length see what he could not, the scheme of its fulfillment. He saw Persia resigning the scepter to Macedonia, Greece to Rome, and Rome to Western Europe, which abuts on the Atlantic. When America was covered with

forests, he anticipated an age when that country would occupy as prominent a place among the nations as had been occupied by Assyria and Rome. Its enormous coal-fields, some of them equal in extent to all England, seem destined to form no mean element in its greatness. If a patch containing but a few square miles has done so much for central England, what may not fields, containing many hundred square leagues, do for the United States ?"

The new metal aluminum is said to be an unquestionable conquest of science, and may be produced in any quantity for $3 a pound. Further improvements are expected to reduce its cost to fifty cents, when it will naturally replace iron in many household and familiar utensils. This discovery is one of the positive scientific achievements of the day.

parts boiling water, mixed to show a strength of three degrees by the alkalimeter, in which the grain, being soaked for two or three minutes, comes out with the outer husk perfectly removed, leaving the wheat bright and clean, and its germinating qualities uninjured.

ployed for the determination of longitude—of The electric telegraph has lately been emFredericton, New Brunswick. Simultaneous signals were made at that place and at Harvard, where the position of the Observatory has been determined by the United States government, without stint of cost or labor, so that it might become the point of reference for the Coast Survey, in which their navy has been for many years engaged. The longitude of Fredericton, as now found, differs twenty-seven seconds from the former determination by astronomical observation-a remarkably small amount.

A Mr. Capplesmith, of New Harmony, Indiana, who has devoted much attention to me. teorology, writes to the Smithsonian Institute that the directions given to mariners and others respecting the barometer are fallacious. Espy, Redfield, Reid, Dove, and others, affirm that the passage of a hurricane or tornado causes a depression of the barometer, which in some cases amounts to two inches; but Mr. Capplesmith says his observations show that the passage produces a rise, and not a fall. The announcement and investigation of this new point are important.

Charcoal.-Wood charcoal possesses a highly absorbent power for ammoniacal gases, sulphuretted hydrogen, sulphurous acid and carbonic acid gas. This property perfectly adapts it to the absorption of putrid exhalations from decaying animal bodies, a layer from one to two inches in thickness being sufficient entirely to absorb the effluvia from large animals. From dead dogs thus covered no effluvia was perceptible, while the decomposition of the bodies was accelerated. This arises from the fact that charcoal absorbs and oxydizes the effluvia, which under ordinary circumstances would be evolved directly into the air; but within the pores of the charcoal they are brought into contact with condensed oxygen, and are thus subjected to a species of low combustion, their carbon being converted into carbonic acid, and their hydrogen into water. Charcoal, therefore, instead of being antiseptic, is precisely and 60 for sewing-machines. Washing-machines

Heber.—The statue which has recently been erected in St. Paul's Cathedral, London, to the memory of Bishop Heber, is said to be unsurpassed in beauty of design and excellence of execution. He is kneeling, attired in his robes, with one hand resting on the Bible, as his support, and the other upon his breast. On the pedestal, beautifully done in bass-relief, he is represented in the act of confirming two Indian converts.

Liebig has published a method of making bread that will not readily turn sour, and that is more nutritious than ordinary bread. "Pure flour," he says, "is not all that is required for alimentation; there wants the addition of a small quantity of lime." It is to eating bread deficient in lime that some of the diseases of prisoners and children are due. By mixing the flour with weak lime-water, not only does it become more nutritious, according to the views of the celebrated chemist, but there is an increase of eight per cent. in the quantity of bread. It is well known that the bakers of Belgium make inferior flour into palatable bread by mixing it with sulphate of copper-a hurtful substance; while lime in the small proportions contemplated, would be harmless, if not beneficial. In this respect, the method of decorticating wheat proposed at Paris by M. Sibille may be worth notice. He makes a wash of one part lime, three parts carbonate of soda, six

Of the patents for inventions issued by the United States government down to the beginning of the present year, we find that 21 were for air-engines, 148 for steam-boilers, 42 for modes of manufacturing India-rubber goods,

modestly claim 309 patents; water-wheels, 327; grain and grass harvesters, 111; plows, 372; straw-cutters, 153; smut-machines, 110; winnowing-machines, 163; and thrashing-machines, 378. For stoves, 682 patents have been issued, exclusive of 478 for designs.

The Allgemeine Zeitung contains an interesting account of the restoration of Leonardo da Vinci's" Last Supper." For three years the perishable immortality of this work has been undergoing a dangerous process, which is now nearly finished. The refectory had once been a cavalry stable during the French occupation of Italy; and this, and the efflorescence of the saltpetre of the wall itself, had caused many spots of color to drop off. This total destruction of parts rendered its transfer to another ground impossible. The colors are now firmly fixed, cannot be rubbed off, and the removal of the dirt of centuries enables the picture to be better seen.

Don Augustin Corassao, colonel in the Peruvian army, professes to have solved the hitherto insoluble problem of squaring the circle. He has published a pamphlet on the subject, and submitted a copy of it to the Council of the University of Santiago, but omits to disclose the modus operandi.
