WATSON, R[ichard] [1737-1816].
Chemical Essays.
Cambridge: Printed by J.Archdeacon, Printer to the University; For T. & J.Merrill. [Vol. V: London: Printed for T.Evans], 17.
5 Volumes. small 8vo. 1 folding table. contemporary quarter calf (rubbed, several joints cracked, spine of Vol. I split, several headpieces chipped). in 2 modern cloth & paper boxes. First Editions of all five volumes: scarce thus. By his own admission, Watson knew nothing of the subject when he was first elected professor of chemistry at Cambridge on the death of John Hadley in 1764. After fourteen months' immersion, he began his lectures, and over the course of the years, he made sound and significant contributions to the science. This is his best know work, containing many notable essays, among them 'Experiments and Observations on various Phenomena attending the Solution of Salts', which won him admission into the Royal Society, his paper on his discovery of the black-bulb thermometer, 'On the Degrees of Heat at which Water Boils', describing an experiment which has since become classical; 'On Pit-coal', suggesting the condensing of the volatile products from coke-ovens, an operation which became of great industrial importance, 'Of the Composition and Analysis of Gunpowder' - his advice to the government in 1787 on the improvement of gunpowder resulted in a saving of 100,000 pounds a year; 'Of the Saltness and Temperature of the Sea', a perceptive contribution to early marine science, &c. cfDuveen p. 610. cfSotheran 15466.

WATSON, Sir William [1715-1787].
Experiments And Observations Tending To Illustrate The Nature And Properties Of Electricity. In one Letter to Martin Folkes, Esq; President, and Two to the Royal Society.
London: Printed for C.Davis, 1746..
8vo. pp. 1 p.l., viii, 3-59. interleaved throughout. a few old ms. corrections in the text. modern bds. (small wormholes through upper blank margin, edges of first leaves chipped). First Edition. An important work by one of the most distinguished figures of this period in the history of electricity, who was described by Priestley as "the most interested and active person in the kingdom in everything relating to [the subject]". Watson, British physician and naturalist, contributed to the 'Philosophical Transactions' during the course of his lifetime more than fifty-eight original papers on electricity, natural history and medicine, many of which are of considerable importance. In 1745 he was awarded the Copley Medal of the Royal Society for his electrical research. Watson was the first to observe the flash of light from the discharge of a Leyden jar, as well as providing the first demonstration of the passage of electricity through a vacuum, and the plus and minus of electricity. The present work contains Watson's first papers on electricity, originally communicated to the Royal Society in 1745 and 1746, including accounts of his experiments relating to the ignition of warm spirits by electrical sparks, and his discovery that although ice as well as water is an 'electric' or 'non-conductor', moist air conducts, thereby explaining the failure of electrical experiments in wet weather. Sotheran 15472. cfWheeler Gift Cat. 333 (3rd Edn.: 1746).

WEISMANN, August [Friedrich Leopold] [1834-1914].
Studies In The Theory Of Descent.With Notes And Additions By The Author Translated And Edited, With Notes, By Raphael Meldola.With A Prefatory Notice By Charles Darwin.
London: Sampson Low, Marston, Searle, & Rivington, 1882..
2 Volumes. 8vo. pp. 1 p.l., [v]-xxxvi, 400; 1 p.l., [401]-729, [1]errata. lacking half-titles. 8 chromolithographed plates. original black-stamped & gilt-lettered cloth (extremities & joints bit rubbed & frayed, 1 gathering sprung, errata crossed out & all corrections entered in ms. by former owner). small book label on title of F.J.Cole. First Edition of the English Translation by Raphael Meldola, with preface by Charles Darwin & a new Engish preface by Weismann (first published in German at Leipzig in 1875-76). [The German zoologist's] most influential contribution to biological thought was his theory of the continuity of the germ plasm, an explanation of heredity and development. He maintained that the germ plasm, the substance of heredity, was transmitted from generation to generation, distinguishing it from the somatoplasm; he also was foremost in his day in denying that acquired characters were inherited. Keeping abreast of current researches on the cell and the growing understanding of the role of the nucleus and the chromosomes in inheritance, Weismann modified the theory of germinal continuity. Cytology repeatedly confirmed the phenomena the existence of which he had presumed with theoretical considerations. He was a strong defender of Darwin's theory of evolution and a leader among Neo-Darwinists arguing for the sufficiency of natural selection.[In the present work he] treated the seasonal dimorphism of butterflies and questions of evolution and heredity.[and] proceeded to construct his own theory of heredity rather than accept Darwin's hypothesis of pangenesis.he decided that acquired characters could not be inherited, for to become inheritable, changes would have to affect the germ plasm itself.".
