In a modest monograph, the author presents in exhaustive and detailed form the technic and mode of procedure for the practice of school hygiene in a large metropolitan area. The author correctly points out that there is much loose organization and haphazard management in this rather new field of child hygiene and welfare. He attempts in this book to project a plan of organization which would fit equally well the problem in the large metropolitan area and in the small community. The management of the large and the small group are well discussed. The activities in which the school physician should take part and which should be his concern are clearly defined in all their possibilities and their limitations. The extent to which the school physician can further disease preventive measures is indicated and also the extent to which he can suggest or introduce the delicate problem of therapeutic procedure.
