ARCH Rachel E. Hoffstadt Eight papers have been published by Dr. Hoff- stodt and her assistants on the nature of viruses. With the aid of an uttrapack. a type of rricroscope used in this work, cell changes resulting from the invasion of virus into the tissue have been studied successfully. Although virus usuolly grows only on the animal which it infects. Dr. Hoffstodt and her staff have successfully grown them on chicken mem- brane. By carefully watching the membrane under the ultrapack the rote of Invasion of the tissue and the reaction of the cells can be determined. Dr. Hoffstadt ond S. I. Reed, assistant, examining an " inoculoted " egg. Donald H. ioughridge A device which may help greatly in future weather prognosticating is the " Cosmic Roy Telescope. " Under the direction of Professor D. H. Loughridge, this bottery of vacuum tubes is aimed heavenward and registers on a complicated set-up of amplified dials the force of cosmic roys hitting the earth. High and low pressure areas, vital to weather fore- costing, have a definite correlation to the intensity of these rays striking the globe and this device may lead to more accurote and dependable forecasts.

Frederick K. Kirsten Among many other accomplishments. Professor Kirsten has recently developed a machine for re- moving dust particles from the air. A great aid to industry, this new machine is expected to eliminate many types of industrial lung trouble such as silicosis and ailments which occur in cement plants and powder mills. The machine removes the entire burden of dust from the air after first separating the large particles from the small. It is also expected to aid hay fever victims, and dangerous dust explosions such as occur in plywood mills will be eliminated when the machine is put In use. Dr. Kirsten with his new dust -removing machine. RESnUCH Stevenson Smith Does a person know which of his two eyes is being stimulated by light if he has no other cues than sensations he gets from his retina? Dr. Smith is here conducting an experiment to determine whether the ability to recognize which eye Is being stimulated is due to the light that enters the eye or to the movements of the eye muscles. This ques- tion has puzzled scientists for many years, and the experiment shown here is only a small port of a long and complicated series of tests. When the answer to this question is found, scientists will know more about brain octlorf and response. Dr. Smith testing Pot Cowan in one of the series of retinal response tests.
