If a fair and impartial estimate of the religion of Confucius be made, it cannot be viewed in any other light than as uncorrupted deism, although he has sometimes been accused of befriending and secretly propagating atheistical sentiments; but such an accusation is as cruel as it is unjust, since the purity of his moral precepts, and the acknowledged rectitude of his whole deportment, are utterly incompatible with such a supposition. He considered the Tyen or Deity as the purest and most perfect essence, principle and source of all things in the boundless universe; who is absolutely independent, omnipotent, the governor and guardian of every thing; possessed of infinite wisdom which nothing can deceive; holy, without partiality, of unlimited goodness and justice. We are at a loss to form any adequate opinion of his sentiments relative to the soul of man and the doctrine of futurity, having no well authenticated data, on which to proceed. His morality is in many instances superior to that of Greece and Rome, 3 R

This is done found to be so severe as to congeal this fluid by the cold by denying what is apparently false, by detecting some of the atmosphere. flaw in the reasoning of the adverse party, by granting their argument, and showing its invalidity, or retorting it upon the adversary.

CONGE, in the French law, a license or permission, granted by a superior to an inferior, which gives him a dispensation from some duty to which he was before obliged. A woman cannot obligate herself without the congé or license of her husband; a monk cannot go out of his convent, without the congé of his superiors.

CONGE' d'elire, in ecclesiastical policy, the king's permission royal to a dean and chapter in the time of a vacancy, to chose a bishop; or to an abbey, or priory, of his own foundation, to choose their abbot or prior.

The king of England, as sovereign patron of all archbishoprics, bishoprics, and other ecclesiastical benefices, had of ancient time free appointment of all ecclesiastical dignities, whensoever they chanced to be void; investing them first per bacculum et annulum, and afterwards by his letters patent; and in course of time he made the election over to others, under certain forms and limitations, as that they should at every vacation, before they choose, demand the king's congé d'elire, and after the election crave his royal assent, &c.

CONGE', in Architecture, a mould in form of a quarter round, or a cavetto, which serves to separate two members from one another; such as that which joins the shaft of the column to the cincture, called also apophyge.

CONGES are also rings or ferrels formerly used in the extremities of wooden pillars, to keep them from splitting, afterwards imitated in stone work.

CONGELATION, signifies the passing of any body from a fluid to a solid state: so that the term is thus applicable to metals when they resume their solid form after being heated, to water when it freezes, to wax, spermaceti, &c. when they become solid after having been rendered fluid by heat; and in general to all processes, where the whole substance of the fluid is converted into a solid but it differs from crystallization; because in the latter process, though the salt passes from a fluid to a solid state, a considerable quantity of liquid is always left, so that the term congelation is never applied in this case.

The process of congelation in all cases depends upon, or at least is accompanied with, the emission of heat, as has been evinced by experiments made not only on water, but on spermaceti, wax, &c.: for in all of these, Is always though the thermometer immersed in them while fluid continued to descend gradually till a certain period, yet it was as constantly observed to remain stationary, or even to ascend while the congelation went on.

It is not known whether all kinds of fluids are naturally capable of congelation or not; though we are certain that there are very great differences among them in this respect. The most difficult of all those of Congelation of which the congelation has been actually ascertained is quicksilver. quicksilver, This was long thought capable of resist

The congelation of quicksilver was first ascertained Experiby M. Joseph Adam Braun, professor of philosophy at ments of Petersburg. He had been employed in making ther- M. Braun, mometrical experiments, not with a view to make the discovery he actually did, but to see how many degrees. of cold he could produce. An excellent opportunity for this occurred on the 14th of December 1759, when the mercury stood naturally at 34, which is now known to be only five or six degrees above its point of congelation. M. Braun, having determined to avail himself of this great degree of natural cold, prepared a freezing mixture of nitric acid and pounded ice, by means of which his thermometer was reduced to -69, Part of the quicksilver had now really congealed; yet so far was M. Braun from entertaining any suspicion of the truth, that he had almost desisted from farther attempts, being satisfied with having so far exceeded all the philosophers who went before him. Animated, however, by the hopes of producing a still greater degree of cold, he renewed the experiment; but having expended all his pounded ice, he was obliged to substitute snow in its place. With this fresh mixture the mercury sunk to 100, 240, and 352°. He then supposed that the thermometer was broken; but on taking it out to observe whether it was so or not, he found the quicksilver fixed, and continuing so for 12 minutes. On repeating the same experiment with another thermometer which had been graduated no lower than 120, all the mercury sunk into the ball, and became solid as before, not beginning to reascend till after a still longer interval of time. Hence the professor concluded that the quicksilver was really frozen, and prepared for making a decisive experiment. This was accomplished on the 25th of the same month, and the bulb of the thermometer broken as soon as the metal was congealed. The mercury was now converted into a solid and shining metallic mass, which extended under the strokes of a pestle, in hardness rather inferior to lead, and yielding a dull sound like that metal. Professor pinus made similar experiments at the same time, employing both thermometers and tubes of a larger bore: in which last he remarked, that the quicksilver fell sensibly on being frozen, assuming a concave surface, and likewise that the congealed pieces sunk in fluid mercury.

The fact being thus established, and fluidity no longer to be considered as an essential property of quicksilver, M. Braun communicated an account of his experiments to the Petersburgh Academy, on the 6th of September 1760; of which a large extract was inserted in the Philosophical Transactions, vol. ii. p. 156. Five years afterwards he published another treatise on the same subject, under the title of Supplement to his former dissertation. In this he declared, that, since his former publication, he had never suffered any winter to elapse without repeating the experiment of congealing quicksilver, and never failed of success when the natural cold was of a sufficient strength for the purpose. This degree of natural cold he supposes to be 10 of Fahrenheit, though some 3 R2
