Response, of course, depends on such variables as light source (stimulus), apparatus, size of the pupil, and location of the area of retina which is stimulated; it is also important that records be obtained under constant standard conditions.

The purpose of this paper is to describe a contact lens for use in recording the ERG in rabbits (Fig. 1). The contact lens developed by Riggs in 1941 made it possible to record the ERG in human beings without discomfort. The present contact lens is a modification of the original (Fig. 1C), which, as used with human beings, was equipped with an electrode (E) identical to that shown in Figure 1.
