This little book is a study in particular of the hygiene of speech, and while the authors very properly give an account of the speech activities, both nervous and muscular, and the various mechanical situations which modify it, they show a very full appreciation that speech is a form of expression which is largely emotionally guided and the product of the child's environment in the largest sense. While the book contains suggestions for dealing with stammerers and stutterers in the way of reeducational exercises and the like, it is replete with good advice on the general hygiene of dealing with the child in the family and the school. Its broad attitude in these matters commends it, and while it does not take up specifically some of the disturbances of speech which are due to specific affect-ladened complexes in the unconscious, it recognizes their existence and importance. The book is a distinctly wholesome discussion of the hygiene of the child from the angle of speech expression.
