‎First appearance of Perrin's doctorial thesis, in which he definitly settled the question of the common nature of cathode rays and of the recently discovered X rays, showing them to be particles. The experiments prepared the way for J.J. Thomson's determination in 1897 of the charge-mass ratio of these particles, electrons. In 1896 Perrin won the Joule Prize of the Royal Society for his experiments on cathode rays and for his preliminary studies on Röntgen's X rays, these investigations formed the content of his thesis. Perrin received the Nobel Prize in Physics in 1926 for this and other work on the discontinuous structure of matter, which put a definite end to the long struggle regarding the question of the physical reality of molecules.""During the 1890s he was attracted to the study of cathode rays, which Crookes had shown to be electrically charged. Even so, there remained controversy whether they were particles (as it seemed they would have to be if they were charged) or whether Crooke's observations were in error and they were actually a form of wave radiation. Perrin settled the matter for all in 1895 by showing that the radiation could be made to impart a large negative charge to a cylinder upon which they fell. The cathode rays must, therefore, consist of negatively-charged material, and must be particles rather than wave. J.J. Thomson was able to determine the mass of the particles and to show that they were much smaller than atoms.""(Asimov).The offered volume contains further notable papers. 14 Memoirs by Marcellin Berthelot.‎

Cailletet and Pictet had worked independently and by different methods. While Cailletet's method had been to compress, cool and expand the gas to be liquefied, Pictet had employed the ""cascade"" process, in which the refrigeration cycles of three different cooling media with successively lower critical temperatures were arranged in series, so that the gas liquefied in first would act as a cooolant in the liquefation of the next. ictet used sulphur dioxide in the first cycle, carbon dioxide in the second and oxygen in the last.

‎First appearance of Playfair's investigations on the Schehallien mountain in Scotland.John Playfair first visited the Scottish mountain, Schiehallion, during Nevil Maskelyne's 1774 plumbline deflection experiment, which was conducted to measure the density of the Earth. The mathematician Charles Hutton analysed the survey data from the experiment, reporting the mean Earth specific gravity as 4.5 in 1778. Playfair undertook a lithological mapping exercise in 1801, to improve the accuracy of Hutton's estimate, and reported a range of 4.564.87 in 1811. The computation of the gravitational effect of topography with variable subsurface density effectively made him the creator of the first geophysical model. As such, not only was Playfair's Schiehallion contribution pioneering in itself, but it was representative of his more significant works in both mathematics and geology, in that he built on existing benchmark work with novel and valuable additions of his own. Although Playfair's map of the extent of the Schiehallion quartzite was quite accurate, the Society's fourth President, John MacCulloch, having visited Schiehallion, was dismissive of Playfair's representation of the subsurface density variation. MacCulloch spent several years searching Scotland for a more favourable site for a plumbline experiment, travels that allowed him to compile the data for his 1836 geological map of Scotland. (John R.

The paper offered introduces THE LAW OF LARGE NUMBERS (Loi universelle des Grandes nombres, pp. 478-79), a key concept in probability theory. Poisson states that all events of a moral as well as of a physical nature are subject to this universal law. His definition (in English translation) on p. 478 reads ""Things of every kind obey a universal lw that we may call the law of large numbers. Its essence is that if we observe a very large number of events of the same nature, which depend on constant causes and on causes that vary irregularly, sometimes in another, 1.e., not progressively in any determined sense, then almost constant proportions will be found among numbers"" (p. 478 in the first memoir).""Prior to the publication of the ""Rechearces"", Poisson presented his principal results and philosophical views to the Academie des Sciences in papers read at the sessions of 14 december 1835 and 11 April 1836.

‎First appearance of Poisson's importent paper on the mathematical treatment of ""specific heats"".""In ""Sur la chaleur des gaz et des vapeurs,"" published in August 1823 in Annales de chimie et de physique, Poisson developed ideas published four months before by Laplace in Book XII of Mécanique céleste. Poisson introduced all the precautions needed to render the confused notion of quantity of heat susceptible to mathematical analysis. He called quantity of heat the magnitude that characterizes the transition of a given mass of gas from an arbitrary initial state of temperature and pressure to another state. This definition makes more abstract the quantitative aspect that naturally follows from the concept of heat as a caloric fluid. Poisson could thus deal comfortably with this magnitude, since for him it is simply a function q of p, p, and ø (pressure, density, and temperature). The equation of state p= ap(1+aø) was already classic, and the growing acceptance of the notions of specific heats, at constant pressure and constant volume, allowed him to write the simple partial differential equation of which should be the integral. He also showed that independently of any additional hypothesis, and whatever the arbitray function used in the integration, the adiabatic transformations (the term did not yet exist) correspond to the formulas p · py = constant and (?+266.67)·p1y= constant, y being the ratio of the specific heats, assumed constant.""(DSB).‎

‎First printing of this milestone paper, containing the first scientific classification of foodstuffs as carbonhydrates, fats, proteins, and water.""The brilliant demonstration in 1824 that the gastric juices of animals contains hydrochloric acid appeared incredible to many of Prout's contemporaries. Yet in 1827 (in the paper offered) they readily adopted his classification of foodstuffs into water, saccharinous (carbonhydrates), oleagineous (fats), and albuminous (proteins). Although Prout promised detailled analyses of the three organic aliments, only those of the saccharinous class were published by him. As a vitalist, Prout maintained that organized bodies (which were composed from organic substances) contained ""independent existing vital principles.""Under the influence of these teleological agents, the four aliments were transformed into blood and tissues. Prout termed the process of digestion and blood formation ""primary assimilation."" ""Secondary assimilation"" (Liebig's ""metamorphosis of tissues"") included both the process of tissue formmation from blood and the destruction and removal of unwanted parts from the animal system. The absorption and removal of water from processed aliments were the principal chemical features of chylification and sanguification, respectively. Organization of processed aliments could not occur, however, without the presence and admixture of minute amounts of water or of elements other than carbon, hydrogen, oxygen, and nitrogen.

The situation was different with nitrogen. The nitrogen he obtained from air constantly showed a slightly higher density than the nitrogen he obtained from any of various compounds. Rayleigh could think of several ways in which the nitrogen obtained from air might be contaminated but none of the possibilities checked out experimentally. He was so frustrated that he went so far as to write to the journal ""Nature"" asking for suggestions. Ramsay, a brilliant Scottish chemist, asked permission to tackle the problem and received it. The upshot was that a new gas, somewhat denser that nitrogen, was discovered to exist in the atmosphere.

‎Regnault announced here that he has found experimental evidence for the approximate nature of Dulong & Petit's Law for both elements and compounds.""His first results on the specific heat of solids were presented to the Academy of Sciences on April 3, 1840. One finds there the first experimental demonstration of the approximate law of Dulong and Petit, which had been ypothesized, rather than established, by these physicists. For 24 pure elements, Regnault demonstrated that this law was only partially true mostly because there was no accepted table of atomic weights at that time."" (Laurie Dahlberg)‎
