Abstract

During the past two years 2,163 students at Iowa State College were tested for colorblindness by means of the Ishihara Test. All the tests were given individually by the writer at the time the students were given a physical examination. This investigation was made possible through the kindness and cooperation of Dr. J. F. Edwards and Dr. H. L. Johnston of the College Hospital staff.
