At the University of Rochester in the past few years, we have been doing work with Public Health support along two entirely different lines. One part has involved the measurement of scattered light and retinal image quality, involving work with excised steer eyes and occasionally other animals. The other work has involved an investigation of the transition from the absolute cone threshold, on the one hand, to the luminance-discrimination threshold on the other. It is the second part of the work that what I wish to say today is based upon.

I would like to acknowledge the help of Dr. William Bush, Dr. Jay Enoch, Mr. Gillray Kandel, and Mrs. Judith Onley, who have participated in various of the experiments which we have done with respect to this particular problem.

I first became interested in this area as a result of reading two articles and seeing a connection between them.
