Cohen covers the field of household medicine, including housing, water, heating, bathing, clothing, exercise, eating, stimulants, childhood, care of sick, accidents, etc. His style is terse and dogmatic, yet not objectionally so. It enables him to cover a great deal of ground and to avoid confusing the reader. Statements that deserve criticism are few and these are not important, as, for instance, "Stoves do not assist at all in ventilation." The book may be recommended as a sensible guide to health and right living.
