Dr. R. D. Gillespie's treatise on Sleep and the Treatment

of its Disorders (Bailliere, Tindall and Cox, 7s. 6d.) is written primarily for the practitioner. It is, however, a book which cannot fail to interest and perhaps help those unfortunate people who are on too familiar terms with the night. The most reassuring information contained in it is that "the effects of insomnia in man are of a trivial nature." This is, indeed, good news for the sleepless and should do much to produce that state of relaxation which is the beginning of sleep. There are many other useful hints contained in the chapter on "Treatment."
