Abstract
THIS work, No. 68 of the popular scientific manuals published by Messrs. Quelle and Meyer, is to some extent the outcome of lectures delivered by the author at technical high schools, modified to meet the requirements of general readers. In addition to sound elementary information on the taking and reduction of observations, it includes the results of the most recent investigations, of the fundamental researches of Hann, Hellmann, and others, and useful references to the historical development of this branch of meteorological science. Chapters i.-v. treat, of aqueous vapour, condensation, formation of fog and clouds, sunshine and cloudiness. Chapters vi.-x. deal with rainfall, snow and hail, exposure of gauges, calculation of results, &c. The remaining chapters, xi.-xiii., refer to the rainfall over the globe, the causes of its unequal distribution, to daily, yearly, and secular periods. The whole will repay careful perusal; among some of the many points of special interest we may note references to Goethe's appreciation of Howard's classification of clouds, to various kinds of glazed frost and hail, and to the effect of wind and exposure on rainfall recprds. Hellmann's classification and reproduction of Neuhauss's photographs of snow crystals are preferred to Glaisher's drawings, which the author hints should now be omitted from text-books. On p. 78 we notice that Chepstow is misprinted as Chepston.
