The Blood Picture and Its Clinical Significance

biological principles. Even now, some seventy-five years after Darwin, man is still looked upon as something super-biologic for whom new super-laws must be framed to separate him from the socalled lower animals. The meticulous presentation of detail in this book would be quite inadequate for the specialist in biology and covers manifestly too much ground in too great detail for any dynamic presentation of biological law. One is amazed at the amount of information suggested by the book. Of its kind it is an excellent book; the illustrations are much better than those ordinarily found. The labor and conscientious attention to detail merit commendation. One can only hope that someday, someone will write a book "showing the place and function of biology in modern thought." H. S. BURR.
