Crewmen, coxswains, and coaches have helped four University scientists develop a new blood test to judge emotional strain, it was learned yesterday.

After a month of injecting a rose colored dye into the arms of crew members, the group came up with a process that indicates whether or not a man's adrenal glands are working.

These organs send hormones to muscles under unusual pressure. By counting the member of certain cells in the blood, doctors can tell when adrenalin is present in the system.

According to a currently scientific theory, a normal person's adrenalin glands issue hormones during times of stress. To prove the theory and the blood test, Dr. Albert E. Renold, research fellow in medicine, Dr. Thomas B. Quigley '29, clinical associate in Surgery, Dr. Harrison E. Kennard '25, assistant surgeon and Dr. George W. Thorn, Hersey Professor of the Theory and Practice of Physics, made the tests on crew members and coaches.
