Jean Andre De Luc's "influence on popular early nineteenth-century British meteorology texts was considerable." "Deluc's early meteorological interest was mainly in measuring heights by barometer, for which he published improved rules (Philosophical Transactions [1771], 158) based on many experiments with hygrometers, thermometers, and barometers, and particularly on the fall in the boiling point of water with diminishing atmospheric pressure and increasing altitude. He devised a hygrometer similar to a mercury thermometer but with an ivory bulb that expanded when moistened and thus caused the mercury to descend (Philosophical Transactions [1773], 404). Humboldt compared the merits of this with Saussure's hair hygrometer: the latter proved better for measuring altitude on mountains and the former for use at sea level, but Deluc's hygrometer worked so slowly that its readings could seldom be combined with those of other instruments." - DSB, IV, p. 28. PROVENANCE: Herbert McLean Evans (1882-1971) was a distinguished endocrinologist and book collector. He studied at Johns Hopkins under Halsted and Cushing but pursued anatomy and research rather than clinical medicine upon graduation. In 1915 Evans became chairman of the Department of Anatomy at the University of California at Berkeley. His research includes work on the role of vitamin E in fertility, the isolation of the growth hormone, and the pituitary follicle stimulating hormone (FSH). In addition to his research and publications, Evans built seven collections of books in the history of science.
