Medicine: Elixirs of Life

Still another "rejuvenation" method is exploited by Dr. William Held, of Chicago, who has returned from three months' study with Dr. Abder- halden, German gland specialist. He uses chimpanzees, but does not transplant their glands. The substance which brings on senility in humans, he says, is "cholin" (a toxic crystalline base allied to the bile). The chimpanzees are "decholinized" by a special process. They have not been penalized by the vices of civilization. Injections of this serum are claimed to restore the conditions of normal youth in the human body. In the near future, says Dr. Held, an age of 100 years will be considered mere infancy.
