année 1777,-410, printed at Berlin.
HISTORY OF THE ACADEMY.
minister of state to the King of Prusia, on the public schools, and the possibility of rendering scholastic instruction more analogous to the duties and occupations of civil life, are sensible and judicious. The observations made by the late M. Lambert at Berlin, and by M. Pucelle, King's counsellor at Mont-Didier, of a remarkable kind of aurora borealis, seen almost throughout Europe, February 26, 1777, are here combined by the secretary of the academy. But the most important article of this first part, is a Latin letter of Professor WALTER, one of the greatest anatomists that any age or country has produced, to the celebrated Dr. HUNTER, physician to the queen, F. R. S. and professor of anatomy at London. The subject of this anatomical epistle is, the veins of the eye in general, and particularly the deep veins of that organ, those of the retina, of the ciliary ligament, of the capsule of the lens, of the vicreous humour, and an account of the central are tery of the retina. No anatomist, before M. WALTER, had formed a just idea of this last artery: M. Walter attributes the cause of their imperfect success to their having filled, with their injections, the arteries and the veins at the same time, and to the great facility with which the injected liquid passes from the arteries into the veins. He followed a different, but also a most difficult and expensive method, which was that of injecting the
veins alone, in order to discover, with more accuracy, their direction and termination; and the discoveries he made by following this method render his letter to the British anatomist fingularly interesting.
This letter is followed by a Memoir concerning the aëriform subStance, which issues, by emanation, from the human body, as also concerning the manner of gathering it. By the Count De Milly, colonel of dragoons, and member of the Royal Academy of Sciences at Paris.-After having shewn the very easy process by which this substance may be gathered, this ingenious man of war enumerates the experiments which he made, in order to alcertain the reality of these emanations. His experiments fatisfactorily prove, that the animal air, which issued from his body in a bath (whose temperature was 27 degrees and a half of Reaumur's thermometer, and that of the atmosphere 17) was different from the air of the atmosphere, and has properties that give it a striking resemblance to what we call fixed air. These experiments are followed by others which Count De Milly made, to ascertain the affinities or relation of the animal air which issues from the pores, to that which is emitted by respiration. This determination of the respective natures and properties of animal gas and pulmonic air will undoubtedly tend to the explication of a multitude of phenomena, concerning which there has been a diversity of opinions. From these experiments we learn, among other things, that air emitted by respiration is a mixture of fixed air diffused through a large quantity of common air, by which the former is carried off, and the pernicious effects of its accumulation are prevented. This explains the principles of fuffocation, and the danger of close and crowded apartments, in which the introduction of common air being obstructed, the emanations of fixed air gain the ascendant.
The four last articles of this historical part, are SEGNER'S demonstration of the general binomial theorem of Newton. A list of the MSS. or printed works, presented to the academy in the year 1777--and the eulogies of Baron d'Esschen and the celebrated chemist Pott, both late members of the academy, both eminent for their successful application to the study of nature, and the former distinguished by his capacity and talents as minister of state to the Landgrave of Hefse-Caffel during the war of 1756.
ExperIMENTAL PHILOSOPHY, 1. Memoir. Concerning the Indian chesnut tree. By M. de FRANCHEVILLE. This tree is called Hyppocastanum by the Botanists, from the property it has of curing purliveness in horses : its fruit is bitter, and the intention of this'memoir is to point out a method, hitherto unknown, of removing this bitterness, and making the trce produce as good chesnuts as those of Lyons.
The means he proposes are transplantion, and engrafting: and he circumstantially describes the manner of proceeding.
II. Memoir. Concerning the Principles of the Tourmaline. M. GERHARD. In this excellent memoir we have, first, a series of curious observations on the Natural History of the Tourmaline, of which three distinct species are particularly described. These observations are followed by a chemical examination of this stone, in which the academician has employed the green and transparent tourmalines of Brasil. From a laborious detail of experiments, made in this examination, it appears, that the conftituent principles of the Tourmaline are, earth of allum,earth of Aint,-a small portion of calcareous earth, and a fat or oily substance. M. GERHARD proceeds afterwards to enquire into the class of stones to which the Tourmaline belongs, and he thinks it comes nearest to the basaltes, both with respect to its figure, and the principles of which it is composed; the latter being of the same nature, and in the same proportions, with those of the Basaltes. Nevertheless, as the analogy between the principles of which precious stone's, the basaltes, the tourmaline, and the zeolite, are composed, is so great, our academician thinks, that the Mineralogists will be obliged to arrange these stones in a new order, under the general title of fones fusible, by way of emi
Under this new order four kinds may be comprehended -the precious stone the tourmaline-the basaltes or schorland the zeolite. The two first are distinguished by their electrical virtues, with this difference, however, that the attractive power of the precious stone must be excited by friction, whereas the tourmaline, in order to become electrical, must be placed on hot ashes, and possesses moreover a repellent virtue. The basaltes is a fusible, but not electrical, stone, and the zeolite is fusible, fometimes electrical, and emits a considerable portion of froth when it is in the period of fufion. Though want of space obliges us to terminate here our account of this curious and elaborate memoir, we cannot conclude it without observing, that there are two phenomena, which furnish several judicious reAections to our academician; the first is, that the lava contains the same principles that compose the tourmaline and the basaltes, and the fecond (which is still more singular and remarkable) is, that the principles of fusible stones, that have been separated, and have afterwards been mixed again in the same proportions in which they had been found, do not submit to fufion, as the stones themselves do.
