"Bref le livre de M. Humphreys est un ouvrage de synthèse, original en plusieurs de ses parties et en tout cas dans sa composition, il groupe d'une façon claire et logique la plupart des phénomènes atmosphériques. Il est riche de faits et d'idées et néanmoins d'une lecture facile et agréable." La Nature, Paris, 16 Avril, 1921. "In this book Professor Humphreys gives us a large amount of information about the mechanics and thermodynamics of the atmosphere, and puts forward many interesting explanations and suggestions. The book covers a large range and by no means takes the form of an ordinary text-book of meteorology. The chapters on atmospheric optics are particularly welcome and cover a want long felt by English readers." **** Quarterly Journal of the Royal Meteorological Society, London, April, 1921. "Meteorology and general phenomena of the atmosphere are the subjects touched upon in this elaborate book which is published under the auspices of The Franklin Institute. An authoritative aspect would be given to it by this fact alone, were such needed. but the authorship of the book is enough to give it full weight." *** "But throughout the work will be found so many points of interest, that, while the science and mathematics of the subject are given fully, the book retains the aspect of literary value very well, so we can certainly recommend it to our readers. Science and Invention, New York, September, 1921. "Traité considérable et détaillé, où sont discutées toutes les questions en rapport avec l'atmosphère qui intéressent la physique du globe. Les lignes suivantes, extraites de la conclusion, en indiquent bien l'esprit et les tendances générales." **** La Geographie, Paris, January, 1922 “**** Brings together from many sources descriptions and explanations of the numerous and complex phenomena of our atmosphere. ***” Scientific American, New York, May, 1922. *****Professor Humphreys has succeeded in gathering together in an orderly manner the various facts and theories, that comprise the Physics of the Air. The book is invaluable to the student of atmospherics." The Coast Artillery Journal, Fortress Monroe, Virginia, December, |
