First appearance of Raoult's two importent papers in which described a method for finding the molecular weight of an organic compound by the determination of the lowering of the freezing point of water that resulted from dissolving that compound in water and the law governing the relation between solutes and vapor pressure."Then in 1882 F.-M. Raoult published his results on the effects of nondissociating organic solutes from which he deduced a general law controlling the lowering of freezing points the first paper offered. Four years later he extended this work to show the effect of solutes on vapor pressure the second paper offered. Having established the effect of nondissociating compounds he was in position to show that salts produced an eeffect which though anomalous could nevertheless be explained by the supposition that a dissolved molecule broke up into other molecules. This work was of great value in supplying a new method for determining molecular weights since the depression of freezing point and vapor pressure as well a the related rise in boiling point later discovered are proportional to the moleculat concentrations ofthe solutions; it was of equal value in supporting the ideas of van't Hoff on osmotic pressure. With the announcement of the dissociation theory of Arrhenius the anomalies were explained and the full significance of the generalizations of Raoult was recognized. Raoult published the formulations of his laws in the "Comptes Rendus" for 1882 and 1887 the papers offered" Leicester a. Klickstein "A Source Book in Chemistry" pp. 471 ff. unknown

1842réf. 44147Leipzig Johann Ambrosius Barth 1842. Without wrappers. In "Annalen der Physik und Chemie. Hrsg. von J.C. Poggendorff" Ergänzungsband 1 Stück 2. Pp. 193-384 a. 1 folded engraved plate. The entire issue offered. Henry's paper: pp. 282-312. First German version of Henry's description of his discovery of self-induction. He missed the credit for the discovery of induction to Faraday but he had done the key experiment ahead of Faraday but Faraday was the first to publish. But he is credited for the discovery of self-induction 1832 and Faraday discovered it independently two years later 1834."In Henry's paper however he explained thet the electric current in a coil can induce another current not only in another coil but in itself. The actual current observed in the coil is then the combination of the original current and the induced current. This is called self induction."Isac Asimov.The issue contains further notable papers Michael Faraday's "Vierzehnte Reihe von Experimental-Untersuchungen über Elektricität" § 2o-22. Nos 1667-1748. Pp. 249-281. First German version. In this paper FARADAYamplifies his theory of electrostatic induction by making further use of the analogy with the induction of magnetism. Whittaker describes the paper as having "THE FUNDAMENTAL EQUATION OF ELECTROSTATICS" as modified in order to take into account the effect of the specific inductive capacity."Whittaker I pp.187-89. unknown

Describes the explorations in the interior of Africa of Daniel Houghton 1740 - 1791 and Mungo Park 1771 - 1806. Daniel Houghton was sent by the African Association the Association for Promoting the Discovery of the Interior Parts of Africa; his instructions were to sail to the mouth of the Gambia navigate the river to the Barra Kunda falls and then to travel overland to the Hausa lands to the east. He was one of the first European explorers in the interior of Africa but after a successful visit in Bambouk territory he disappeared somewhere on his journey to Timbuctoo his last despatch being in July 1791. Mungo Park was then sent by the African Association and travelled more extensively in West Africa. He published the book "Travels in the interior districts of Africa" in 1799 i.e. this book precedes Park's publication. Uncommon. 1st Edition. Leather. Chez Tavernier hardcover

First printing of these two milestone-papers in physiology in which Bernard discovers and isolates glycogen from the liver shows that it is converted into blood glucose and discovers the process of gluconeogenesis. He further creates the concepts "experimental determination" and "local interieur"Bernard undertook the task of tracing out the various transformations of food stuffs within the animal organism beginning with the carbohydrates; and he not only found contrary to the accepted view that sugar was formed in the liver but he was also able to isolate a substance from the hepatic tissue which though not sugar was converted by fermentation into dextrose. He made a special study of its properties and called it "glycogen"."The culmination of Bernard's work on the glycogenic function of the liver. He invented the term "internal secretion" and can be said to have started the scientific investigation of the internal secretions although for 30 years the significance of his work was not generally realized. By his research on glycogene Bernard showed that the body not only can break down but can also build up complex chemical substances."Garrison & Morton .Claude Bernard 1813-78 was a key figure in French nineteenth-century science and one of the world's great physiologists. With good reason he has been called the ‘father of experimental medicine’.Garrison & Morton No. 1000 a. 999.1 unknown

First appearance of the first exposition of the glycogenic function of the liver - one of the greatest physiological discoveries of the 19th century. Bernard showed that the liver builds up complex substances including glycogen from the nutriment brought to it by the blood and that these are subsequently modified for distribution to the body.Dibner "Heralds of Science" No 131 - Horblit "One Hundred Books famous in Science" No. 11a here listing "Nouvelle Fonction du Foie" from 1853 but with the remark "The work appeared earlier in abbreviated form in the "Comptes rendus" the paper offered. - Exhibition of First Editions of Epochal Achievements in the History of Science Berkeley 1934.

Pp. 873-1024 textillustr. a. 1 plate. Entire issue offered. Chadwick & Bieler's paper: pp. 923-940 textillustr. First printingof this milestone paper in which the strong nuclear forces are mentioned for the first time."It was only in 1921 that Chadwick had first shown that at very small distances the interactions of alpha particles with the atomic nucleus did not follow exactly the inverse square law predicted from the repulsion of their positive electrical scharges. Chadwick concluded that his experiments showed that these nuclear forces are of "very great intensity". According to Pais this is THE FIRST PUBLISHED STATEMENT ABOUT THE EXISTENCE OF A STRONG NUCLEAR FORCE. This 'new force' interpretation was disputed untill well into 1920s."Hey & Walters."In any event Chadwick and Bieler's final conclusion avoid all reference to a possible electromagnetic cause for the deviations from the simple theory: "The present experiments do not seem to throw any light on the nature of the law of variation of the forces at the seat of an electric charge but merely show that the forces are of very great intensity. It is our task to find some field of force which will reproduce these effects." I consider this statement made in 1921 as marking the birth of the strong interaction."Pais in "Inward Bound" p. 240. unknown
