With the titlepage to volume 57. <br/><br/><em>First appearance of a classic paper in which Proust describes his discovery of Grape.Sugar and the identificationof this with glucose. He investigated the varieties of sugar that occur in sweet vegetable juices distinguishing three kinds and he showed that the sugar in grapes of which he announced the existence to his classes at Madrid is identical with that obtained from honey by the Russian chemist J. T. Lowitz.Proust is famous for his work on the steadiness of composition of chemical compounds."In chemistry the law of definite proportions sometimes called Proust's Law states that a chemical compound always contains exactly the same proportion of elements by mass. An equivalent statement is the law of constant composition which states that all samples of a given chemical compound have the same elemental composition. For example oxygen makes up 8/9 of the mass of any sample of pure water while hydrogen makes up the remaining 1/9 of the mass. Along with the law of multiple proportions the law of definite proportions forms the basis of stoichiometry."Wikipedia. </em> unknown

He named them Fuchsian functions after the mathematician Lazarus Fuchs because Fuchs was known for being a good teacher and had researched on differential equations and the theory of functions. Poincaré actually developed the concept of these functions as part of his doctoral thesis. Under Poincaré's definition an automorphic function is one which is analytic in its domain and is invariant under a discrete infinite group of linear fractional transformations. Automorphic functions then generalize both trigonometric and elliptic functions." Wikipedia. </em> unknown

"Before he was thirty years of age Poincaré became world famous with his epoch-making discovery of the "automorphic functions" of one complex variable or as he called them the "fuchsian" and "kleinean" functions." DSB.These manuscripts written between 28 June and 20 December 1880 show in detail how Poincaré exploited a series of insights to arrive at his first major contribution to mathematics: the discovery of the automorphic functions. In particular the manuscripts corroborate Poincaré's introspective account of this discovery 1908 in which the real key to his discovery is given to be the recognition that the transformations he had used to define Fuchsian functions are identical with those of non-Euclidean geometry. See Walter Poincaré Jules Henri French mathematician and scientist.The idea was to come in an indirect way from the work of his doctoral thesis on differential equations. His results applied only to restricted classes of functions and Poincaré wanted to generalize these results but as a route towards this he looked for a class functions where solutions did not exist. This led him to functions he named Fuchsian functions after Lazarus Fuchs but were later named automorphic functions. First editions and first publications of these epochmaking papers representing the discovery of "automorphic functions" or as Poincaré himself called them the "Fuchsian" and "Kleinian" functions."By 1884 Poincaré published five major papers on automorphic functions in the first five volumes of the new Acta Mathematica. When the first of these was published in the first volume of the new Acta Mathematica Kronecker warned the editor Mittag-Leffler that this immature and obscure article would kill the journal. Guided by the theory of elliptic functions Poincarë invented a new class of automorphic functions. This class was obtained by considering the inverse function of the ratio of two linear independent solutions of an equation. Thus this entire class of linear diffrential equations is solved by the use of these new transcendental functions of Poincaré." Morris Kline.Poincaré explains how he discovered the Automorphic Functions: "For fifteen days I strove to prove that there could not be any functions like those I have since called Fuchsian functions I was then very ignorant; every day I seated myself at my work table stayed an hour or two tried a great number of combinations and reached no results. One evening contrary to my custom I drank black coffee and could not sleep. Ideas rose in crowds; I felt them collide until pairs interlocked so to speak making a stable combination. By the next morning I had established the existence of a Class of Fuchsian functions those which come from hypergeometric series; i had only to write out the results which took but a few hours.the transformations that I had used to define the Fuchsian functions were identical with those of Non-Euclidean geometry." </em> hardcover

These importent observations lead directly to Röntgens discovery of the Röntgen Rays."Cathode rays were first observed by Julius Plücker in 1859 the paper offered. They are rays which are found in the neighbourhood of the point of exit of an electrical current passing through a Geissler tube. These rays stimulated intense interest and experiment. William Crookes greatly improved these discharge tubes and intensified the degree of rarification of gases within them. The tubes in this form is known as Crookes tube. Crookes declared his conciction that the cathode rays represented matter in a fourth hitherto unobserved form.It was reserved for J.J. Thomson in 1908 to discover the true nature of the cathode rays."PMM no 386. </em> unknown
