On Mice

Dr. E. B. Krumbhaar of the Philadelphia General Hospital, and Mrs. Krumbharr returned last week from England. Mrs. Krumbharr has been playing hockey abroad, with the American women's team, competing in Europe and England. Dr. Krumbhaar has been investigating hospitals.

As an expert of radium cancer, he stated that greater progress has been made during the past five years, in finding out just what cancer is and what is its cause, than was done during the previous 500 years. Experts at the London Cancer Hospital are able to cause cancer on mice. Isoprene tar is applied daily upon the backs of mice for six months. A wart forms and then quickly develops into a cancer. Chronic irritation also causes cancer. These discoveries are important to the study of the mysterious disease.
