In this analysis the carbonic acid united with a portion of the lime. The magnesia was not estimated. The silicates which were left undissolved, were found to contain silica, lime, magnesia, iron, and manganese. The quantity operated on was too small to determine the proportions by weight. In 1860, Prof. Owen made a complete analysis of a spring on the hill. The various analyses gave in the sediment Organic Matter (appocrinic acid?) 0.0048 Carbonate of Lime; a little Oxide of Iron, and partly combined with the organic acid, and a trace of Carbonate of Magnesia. Silica, with a little Sulphate of Lime, tinged with Oxides of Iron, and Manganese, 0.0092 0.0160 0.0300 The above was obtained from 1000 grammes evaporated to dryThe part of the matter soluble in water after evaporating to ness. dryness and ignition: The part insoluble in water after evaporation and before ignition: Organic Matter, (appocrinic acid) burnt off by ignition, Silica and Silicates, insoluble in acids, Carbonate of Lime, 0.0018 0-0600 0.0600 Carbonate of Magnesia, Alumina and Oxide of Iron, 0.0040 0.0010 0.1268 Calculating the probable combinations of these acids and bases, as they are, in all probability, united in water, we have: Approcrinate? of Protoxide of Iron, Silica and insoluble Silicates, Bicarbonate of Lime, 0.025 0.060 0.086 0.006 0.001 0.0170 0.0040 0.0002 0.0026 0.000015 There is (he says) still an excess of magnesia remaining, which probably exists as iodide and bromide of magnesia; for, though Dr. Elderhorst, operating on 1000 grammes, was not able to detect any iodine or bromine, yet, when I extracted the solid residue from 2000 grammes with alcohol, evaporated this to dryness at a low temperature, and tested it with protochloride of palladium, the watery solution was slightly tinged yellowish-brown, indicative of a trace of iodine, and, if larger quantities of the water were operated on, the iodine and bromine could, in all probability, be distinctly brought out. In drawing conclusions from the above analyses, I would give as the constituents of these waters, omitting however, the proportions, silicates with bases, bicarbonates of lime, bicarbonates of magnesia, alumina, with oxide of iron, carbonate of soda, carbonate of potash, sulphate of magnesia, chloride of magnesia, oxide of manganese, sulphate of lime, bromine a trace, iodine a trace, organic matter a trace. There may exist a trace of lithia (carbonas) and arsenic a trace, combined with iron or lime, yet it is not indicated by the above experiments, and we have no assurance that they exist. There are fifty-four springs in all, which have a mean temperature of 134° Fah., and range respectively from 63° to 150° Fah. They totally discharge 317 gallons of water per minute. The springs are situated on the western slope of Hot Spring Mountain (which is a margin of the Ozark Mountains) at an estimated elevation of 360 feet above the level of the sea, and about fifty-five miles westerly from Little Rock. Invalids of a colder latitude will find this a delightful resort for the fall, winter and spring months. These waters enjoy great celebrity for their benign effects over rheumatism, gout, skin diseases as a class, scrofulous ulcerations, spinal diseases, nervous affections generally, uterine diseases as a class, mercurial, mercurio-syphilitic, and all forms of syphilitic diseases, over which maladies, and in fact, many forms of chronic diseases, its effects are truly astonishing. These waters are highly stimulating, and are considered by the majority of patients as a species of luxury. This effect is due to the large quantity of free carbonic acid which the water contains. EXTRACTS FROM DR. GREENE'S CLINICS. At the Ann Harbor University, Michigan. AMPUTATION OF THIGH.-The gentleman with deformed limb who presented himself on a previous day, submitted to amputation, which was performed by the circular method at the middle of the thigh. Operation nicely borne. Prof. G. presented to the class another limb which he had removed (at the same point) from a private patient, a few days before, in which the lower end of the femur was the seat of malignant disease. Patient was a shoemaker, and the disease arose at the point where he was accustomed to hold the boot or shoe while pegging. Dr. G. said that the fact that there was in this case a local exciting cause, and that there was no cancer in the family, rendered the prognosis much more favorable than in ordinary cases of similar affections. FIBROUS TUMOR OF EAR.-Occurred in boy 9 years old. Tumor as large as a walnut. Was removed one year ago but has returned. On account of its recurrent character the wound produced by its removal was left open to heal by. granulation, and to be dressed with acetic acid, glycero-tannin, &c., to prevent recurrence. FIBRO-CELLULAR TUMOR OF THE EYE.-Boy 11 years old. a grain of powder in eye two years ago. Soon after tumor appeared. It was of blood-red color, size of a bean, and extending from the cornea nearly to the canthus. Was clearly dissected from the eyeball. Will not probably return. NECROSIS OF HUMERUS.-Little girl of 11 years. Had periostitis one year ago, producing death of the bone from elbow to shoulder. The arm now badly swollen and discharging pus freely through numerous fistulas and openings. The dead bone is now enclosed in a thick new shell of bone thrown around the old. This was opened with chisels in three places just above the elbow, at the middle of the arm and just below the shoulder, and this dead bone removed, Will have a useful arm. GRANULAR LIDS.-Man aged 35. Has had bad eyes for three years. Has spent large sums of money for "all sorts of treatment." Is now nearly blind from opacities of cornea, which are the result of the long continued frictions from the granulations. So great is the intolerance of light that he is obliged to keep the eyes constantly and heavily shaded, Prof. G. said: "This is a very common and a very important affection, inasmuch as, either from neglect of seasonable treatment or from that which is improper in its character, a large number of eyes are annually ruined, to say nothing of the larger number that are more or less impaired. The great fault with the treatment generally is that it is not unnecessarily but injuriously severe. Caustic preparations are used in a routine manner, and as often used, keep up the very disease they are intended to cure. These may be used occasionally for the removal of large granulations or for profoundly modifying the changed nutrition of the past. But they should be used only for a well defined purpose and then omitted, being followed by simpler dressings. Almost never is it necessary or proper to repeat them except at long intervals, and, in fact, for several years I have hardly used them. Occasionally use the nitrate of silver, sulphate of copper, iodine &c., but am usually content with free scarifications of the lids, shaving off large granulations and applying some glycerole, that of tannin in different strengths being the best." After speaking at some length of the value of glycerine as a solvent of any substance to be applied to the eye, and of the peculiar manner in which the action of these substances is modified by the glycerine; also of the importance of attending carefully to the constitutional conditions in these cases, and furthermore of the necessity, here, as everywhere in the practice of medicine and surgery, of avoiding routineism, taking every case upon its own individual merits and treating it upon general principles, Dr. G. shaved off the granulations and applied glycero-tannin two drachms to the ounce. The immediate effect of the operation was great relief from pain and intolerance of light, and the patient is now (Feb. 5th), rapidly regaining his sight, the opacities being of a character to absorb after friction is removed. ECZEMA CAPITIS-Scald Head.-Several cases of this affection presented, but this was especially interesting as occurring in a man, middle aged, apparently in good health, and who had never been subject to any form of eruption. It involved the entire scalp. Treatment advised alteratives, and, locally, oil of cade and glycerine. ENLARGED LYMPHATICS-GLANDS OF THE NECK.-Man aged 35. Has tumors of various sizes, from that of an almond to a goose egg on both sides of head and neck, and on right side extending into the chest. No surgical interference advised, but such constitutional measures as would improve general nutrition. NEGLECTED FELON (Whitlow).—A man aged 40 presented himself with the thumb enormously swollen, distorted, and almost mortified, with several fistulous openings leading to necrosed bone. A free incision was made and the dead bone removed. Prof. G. remarked that this was a common case; instead of being arrested at once, as they always are if freely and properly incised, and thus the destruction or deformity of a member avoided, these felons are poulticed day after day, and sometimes week after week, till suppuration takes place, and in many of the cases after all the suffering the patient finds his finger or hand permanently crippled, if not destroyed. Ninety-nine one-hundredths of these might be cured in 48 hours by proper treatment. DOUBLE HARE LIP.-Little child 5 months old. Deformity very great, the two fissures being wide, extending into each nostril, and an unsightly "snout" projecting in the center; the nose being flattened almost even with the face. The central portion was cut |
