So That Animals May Grow in a "Germ Free World". One complete unit for raising animals in a "germ free world"... a corner of the sterilization room in the bacteriological laboratories at the University of Notre Dame. As a result of this interesting experiment scientists have discovered that health without germs is impossible, and that life as man knows it is unlikely without the aid of germs. Animals are delivered in the first cage and passed into #2 for raising; when mature they are kept for testing and examination in #3. Through the control panel at the left, the operator handles sterilization of food, air pressure, humidity, temperature and air filtering. The germ free experimental work is under the direction of Professor J. A. Revniers.
