Dr. George Martin Kober celebrated his seventieth birthday in 1920. He now presents the first volume of his autobiography, which covers his early life and reminiscenses of Germany, his arrival in the United States, and his relationship to the United States Army through the campaign of General Howard, about 1878. The book is full of interesting personal material; however, the detail is so overwhelming as to make the work forbidding to all except those who have had personal relations or acquaintanceship with its author. Volume I covers a period when the United States and medicine in the United States were undergoing growing pains. No doubt the subsequent volumes will carry the author through the adolescence and maturity of the advancement of medical education and bacterial investigation, in which he has played a considerable part.
