part of the material of this discussion has been provided by the author's own 

 important researches. 



We offer our congratulations to Mr. Jeans and couple with them the 

 hope that he will be able to find time to pursue some of the problems further 

 and succeed in elucidating some of the many difficulties with which the 



subject bristles.

Practical Exercises on the Weather and Climate of the British Isles and 

 North-West Europe. By W. F. Stacey, F.R.G.S., F.R.Met.Soc, 

 University College, Reading. [Pp. 64.] (Cambridge : at the Uni- 

 versity Press, 1919. Price 2s. 6d. net.) 



The aim of this book is to teach the student something about the weather 

 of the British Isles, by making him construct for himself a series of maps 

 similar to those appearing in the Daily Weather Report of the Meteorological 

 Office, from which publications the data have in every case been taken. 

 The examples have been chosen with a view to familiarising him with the 

 chief types of pressure distribution and the weather that accompanies them. 

 Thus we have illustrations of the Cyclone and Anticyclone in summer and 

 winter, the formation of a secondary depression, the Col and V-shaped 

 depressions. The method of drawing isobars, and their use for estimating 

 the direction and strength of the wind, are explained at an early stage of 

 the book, together with the Beaufort Weather Notation which is in general 

 use all over the world. The concluding exercises deal with the most impor- 

 tant types of weather, classified according to the general drift of the wind 

 across the British Isles, namely, the E. ( S.W., N.W., and W. types. 



Teachers of geography should find this carefully thought-out work of 

 great assistance.

The Study of the Weather. By E.H. Chapman, M.A., B.Sc. [Pp. xii + 131.] 

 (Cambridge : at the University Press. Price 3s. 6d. net.) 



This book is intended primarily for use in schools, but the admirable way 

 in which the elementary stages of a difficult subject are treated gives it a 

 wider scope. From exercises in weather study of the simplest kind the 

 student is led gradually to the consideration of more difficult problems. He 

 should finally be in a position to appreciate fully the information conveyed 

 by modern synoptic weather-charts, and will experience no difficulty in 

 passing on to the more advanced textbooks on Meteorology. From the 

 earliest chapters, which deal with the observation and recording of wind 

 and weather, the exercises are cleverly chosen to stimulate thought. Clouds, 

 and their classification, are introduced at an early stage. The remarks 

 on this subject are illustrated by a number of photographs of great beauty, 

 of which two were taken from an aeroplane and show the magnificent cloud 

 panorama that is so often seen when an aeronaut passes through the level 

 of the lower clouds. Weather which can be recorded without instruments, 

 such as fog, mist, dew, hoar-frost, etc., is considered next, and then the 

 commoner instruments, such as the rain-gauge and the thermometer. A 

 whole chapter is devoted to the more difficult problem of measuring the 

 pressure of the air, and a full description of the Kew-pattern barometer, 

 graduated in millibars, is given. Passing from the weather at the observer's 

 own locality, an explanation is given of the way in which simultaneous 

 observations from stations in different parts of the British Isles, and from 

 abroad, are dealt with by the Meteorological Office in London, and the
