Introduction
Examining the treatment in meteorological works of thermodynamical problems involving the ideas of surface tension and of adsorption, one is struck by the fact that such questions are almost always dealt with in a fragmentary manner. The reader is referred to various works which he is recommended to study in order to understand the statements presented. The multiplicity of sources on which it is desirable to draw leads him to feel the need for a general treatment, and to wish for a single account uniting in a coherent manner the various problems of a similar nature involving the thermodynamics of capillarity. Only an account of this kind enables one to get to the root of problems, to perceive what physical hypotheses are required in the process, and to judge the consistency or inconsistency of various theories. For these reasons we considered it useful to present, under the title of Thermodynamics of Clouds, a coherent and rational account, requiring only a little knowledge of general thermodynamics, which takes up each idea from the beginning and allows the reader to appreciate the degree of rigor or of approximation at each stage, and which discusses each hypothesis and develops each theory with a clear statement of the basic physical concepts. We
