It is not long since we noticed the first edition of this work. The second appears with some valuable additions and a general revision The principal additional matter is a chapter on the relation of insects to human diseases, a subject which has come very much to the fore within the last few years. The author's statements on the harmlessness of liqueurs or cordials, with the exception of absinthe, is not in accord with the latest French pronouncement on the subject, which, we think, must be based on as full testimony and study as any that the author has given to it. Aside from their alcoholic content, if we are not mistaken, liqueurs are declared by French authority to be decidedly harmful in themselves. Taken as a whole the book, we think, will maintain the popularity the former edition has received.
