The question of how best to secure early treatment for sufferers from mental derangement has long engaged the attention of the medical profession. It will not therefore, we premise, be out of place to scrutinise some of the more recent pronouncements on this subject. and we could not probably find a more appropriate text for discussion in this connection than the little volume on Shell-Shock by Profs. Elliot-Smith and Pear, a second edition of which has lately appeared, the first having been rapidly exhausted. We welcome this fact as showing that more or less general interest in this most vital and important subject is being aroused, and we hope the demand will continue, although, as will be seen, we have perused its contents with somewhat mingled feelings, especially when taken in connection with an address delivered, since the publication of the book, by Prof. Elliot-Smith at the Royal Institution for Public Health.
