This booklet represents a complete rewriting of the previous issue. Special chapters are devoted to the child's physical surroundings, preservation of health and prevention of disease, the teeth, food and eating habits, sleep, clothing and play. Special attention is given to the physical and mental training and welfare through the various age periods. The material is well handled and covers the well infant and preschool child in a practical and comprehensive manner. The chapter covering the sick child makes no therapeutic suggestions and emphasizes the dangers of delay in instituting medical care. The booklet is one that physicians can recommend to their patients.
