Looking backwards over a full and useful life, Dr. Lorenz, the famous ""bloodness surgeon"" of Vienna, tells his life story. There is none of the charlatan indicated, though he decries the newspaper publicity in America that sometimes gave that impression. He tells how he turned to bone and joint work when carbollic poisoning necessitated his giving up internal surgery. A very human autobiography, as any honest doctor's should be --and full of simple, friendly anecdotal material about his home life, his family and friends -- and his ideals. Patients are veiled in anonymity -- but ""cases"" play their part. Call to attention of doctors among your customers. The largest market will be there.
