London, Harrison and Sons, 1897. No wrappers. Extracted from "Proceedings of the Royal Society", Vol. 61. Pp. 401-413. First printing of Galton's "Law of ancestral Heredity"Galton's ancestral law states that the two parent contribute between them on average one-half of the total heritage of the offspring, the four grandparents one-quarter, and so on. He interpreted this law both as a representation of the separate contributions of each ancestor to the heritage of the offspring and as a multiple regression formula for predicting the value of a trait from ancestral values.Garrison & Morton: 239.

Paris, Victor Masson, 1844. No wrappers. Extracted from "Annales de Chimie et de Physique", 3me Series - Tome 11. Pp. 273-335 and 1 large folded engraved plate (apparatus). With the halftitlepage to volume 11. First printing of an importent paper in which Regnault found the connection between vapour pressure of steam at different temperatures.Henri Victor Regnault improved the method of Dalton to measure the elastic force of vapours at saturation. At the boiling point of a liquid, the elastic force of its vapour is equal to the supported pressure. Thus, if one boils water in an enclosure under increasing pressure conditions, water will reach increasing boiling temperatures at the same time. For each case, the elastic force of vapour will be equal to the imposed pressure.

New York, Cornell University Press, 1957. 8vo. Original full blue cloth. Upper capital bumped, otherwise a nice and clean copy. With the ownership-signature of "W. V. Quine" to front free end-paper and "With the compliments of the Author and Publisher"-card laid in. XI, (1), 203 pp. Quine´s copy of the first edition of Chrisholm's first publication, in which he occupies himself with: "some of the philosophical puzzles or problems that arise when we think and talk about perceiving.""Roderick Milton Chisholm is widely regarded as one of the most creative, productive, and influential American philosophers of the 20th Century. Chisholm worked in epistemology, metaphysics, ethics, philosophy of language, philosophy of mind, and other areas. His work constitutes a grand philosophical system somewhat in the manner of Leibniz or Descartes. Chisholm continually refined - and sometimes utterly revised - his views." (SEP).Willard Van Orman Quine was an American philosopher who in a Leiter-poll made by philosophers was rated as the fifth most important philosopher in the last two centuries only superseded by Ludwig Wittgenstein, Gottlob Frege, Bertrand Russell and John Stuart Mill.

(Paris, Jean Boudot, 1702). 4to. Without wrappers. Extracted from "Mémoires de l'Academie des Sciences. Année 1699". Pp. 1-13 and 1 folded engravedplate. First printing of a major paper in mathematical physics by Varignon which describes falling bodies by help of the new calculus. "Nevertheless, he (Leibnitz) encouraged Varignon to ceae de bating principles and to start developing mechanical applications of the new mathematics. The questions that Varignon subsequently treated show how faithfully he followed Leibniz's advice."(DSB XIII, p. 586)."In working with the model of falling bodies, Varignon encountered difficulties in obtaining acceleration as a second derivative. This problem had the advantage, however, of obliging him to reassess the importance of the new differential and integral calculus. His acceptance of the new procedures occurred between 1692 and 1695, and he was among those who gave the most favorable reception to the publication of L’Hospital’s Analyse des infiniment petits in 1696."(DSB).

(Leipzig, Johann Ambrosius Barth, 1834). Without wrappers. Extracted from "Annalen der Physik und Chemie. Hrsg.von Poggendorff", Bd. 31, No 15-17. Faraday's paper:pp. 225-245. Clean and fine. First appearance in German of this importent paper in which Faraday announces his discoveries of the conductability of liquids "a new law of electric conduction"."The author, while prosecuting his rechearches on electr-chemical decomposition, oberved some phenomena which, appeared to be referable to a general law of electric conduction not hitherto recognized. He found that an electric current from a voltaic battery, which is readily conducted by water, did not pass through ice: even the thinnest film of iice, interposed in the circuit, was sufficient to intercept all electrical influence of such low intensities as that produced, by the voltaic apparatus, although it allows of the transmission of electricity of such high intensity that ecited by the common electrical machine. The author ascertained that a great number of other substances, which are solid at ordinary temperatures, do not conduct the electric current from the volataic battery until they are liquified." (Abstract).From 1831 to 1852 Michael Faraday published his "Experimental Researches in Electricity" in The Philosophical Transactions of the Royal Society. These papers contain not only an impressive series of experimental discoveries, but also a collection of heterodox theoretical concepts on the nature of these phenomena expressed in terms of lines of forces and fields. He published 30 papers in all under this general title.They represents Faraday's most importent work, are classics in both chemistry and physics and are the experimental foundations for Maxwell's electro-magnetic theory of light, using Faraday's concepts of lines of force or tubes of magnetic and electrical forces. His many experiments on the effects of electricity and magnetism presented in these papers lead to the fundamental discoveries of 'induced electricity' (the Farday current), the electronic state of matter, the identity of electricity from different sources, equivalents in electro-chemical decomposition, electrostatic induction, hydro-electricity, diamagnetism, relation of gravity to electricity, atmospheric magnetism and many other."Among experimental philosophers Faraday holds by universal consent the foremost place. The memoirs in which his discoveries are enshrined will never ceaseto be read with admiration and delight; and future generations will preserve with an affection not less enduring the personal records and familiar letters, which recall the memory of his humble and unselfish spirit."(Edmund Whittaker in 'A History of the Theories of Aether and Electricity' p. 197.
