‎First edition of a fundamental work in Meteorology in which Saussure describes how to construct a hygrometer from human hair that can measure the relative humidity, and discussing the principles behind it. Cuvier regarded this book as one of the greatest contributions to science of the eighteenth century.""A milestone work in chemistry, physics, and meteorology, which established hygrometry as an exact science. Primarely a geologist who explored and published on the Alps, Saussure (1740-1788) was the first to prove that air expands and becomes less dense the more humidity it contains. In these Essais (the work offered) he describes his experiments with the hair hygrometer of his invention and his theory of the evaporation and hygrometry with their applications to meteorology. he also enunciates his theory of the evaporation of water in hydrogen, carbon dioxide, and other gases.""(Neville II, p. 427 a).""In his essay on the theoretical principles of hygrometry (which he conceives as ""the art of measuring the absolute quantity of water suspended in the air""), De Saussure distinguishes three classes of methods of determining humidity, which respectively utilize (i) observations of changes in the weight, dimensions, or shape, of a hygroscopic body" (ii) observations of the capacity of the air for taking up water" and (iii) observations of the quantity of water condensing from the air under given conditions on a cold surface, or of the degree of cold necessary to start such an condensation...""(Wolf ""A History of Science , Technology, & Philosophy in the 18th Century"" I, p. 326 ff.).Partington III, 763. - Partington ""Breakthroughs"" 1783 M - Poggendorff II, 755-56.‎
