A Survey of Child Psychiatry

other hand, for the practitioner who plies his profession in a remote locality, whether in the British Isles or in a distant corner of the world, it is very useful to have a pocket companion like this to refer to when he needs guidance on some point or, perhaps more often, a hint as to treatment. For such post-graduate clients this little book will be found very suitable. Very properly considerable attention has been given to the therapeutic section. The directions given chapter by chapter are sound, concise, and practical. We notice two points at which to cavil, neoarsphenamine is recommended for mycosis fungoides, although it is generally agreed that salvarsan derivatives do more harm than good in that disease, and in the section on psoriasis it is claimed that cignolin does not stain clothes. Our experience is that it certainly does. Still these small criticisms do not alter our opinion that many a doctor will do well when about to venture to some locality where he will be very much on his own, to slip into his pocket a copy of Dr. McKenna's "Aids to Dermatology and Venereal Disease." It is very likely to come in useful.
