The Health of Americans

lishers is to cater to the overlapping tastes of two groups of biologists. For those with more eclectic tastes and limited budgets, it is possible to purchase each of the articles separately as an off print at a total cost which is less than that of the book. Therefore at the cost of losing the introductory paragraphs to each section, and the index, one could make one's own selection and take up book binding as a hobby. Since I have no intention of taking up book binding, I am glad to have this book and will treasure it for containing selections from the excellent series of articles on genetics that are continuing to appear regularly in Scientific American.
