Weather Forecasting. By Francis S. Granger. (H. B. Saxton, Nottingham.

2s. 6d. net.)—We may allow that Mr. Granger has done useful work by accumulating and arranging the observations made during a considerable period of time. The 'wise man said: "He that observeth the clouds shall not reap " ; still, it is a good thing to be instructed as to what different clouds mean, and this is one of the things which we may learn from this little treatise. Of course our insular situation makes weather forecasting specially difficult. Everything may be upset by some rapid change in oceanic conditions. Hence the value of the official forecasts ; even these, though far more accurate than they were, are liable to error, if the word ought to be used when the prediction is justified by all that is at the time within reach of the predicter. Anyhow, this book will be found well worthy of notice.
