Health maintenance is largely a personal responsibility. This short compilation of information concerning personal hygiene, originally prepared for radio use, has been revised and brought down to date. Cleanliness, immunization against infectious diseases, school hygiene, food, posture, sport, care of the hair and scalp, and first aid are among the subjects briefly but clearly discussed. A short bibliography is appended. This booklet serves as a useful guide to a few of the phases of personal hygiene.
