Doss begins with a very simple explanation, somewhere between Showers' (1965) and Weart's (1970), of what skin is made of, what happens when you get hot, cold, or hurt, and (briefly) what gives it color. Hair and nails are similarly treated, with differences in the former (straight or curly, dark or light) noted in stride. The last third of the book is less of-a-piece, dealing sketchily with mosquito bites and bee stings, the basic four food groups, and first aid for cuts and burns--as well as with pimples, warts, and other skin problems. However, the accompanying cross-section drawings of blisters, blackheads, etc., are informative, as are the obligatory ones of skin layers earlier on. Supplementary.
