The form of the locust electroretinogram depends upon the type of electrode used, and the contact of the electrode with the retina. The critical flicker frequency was measured. This is of the order of 30-40 c.p.s. under the conditions of illumination used. The c.f.f. is higher when the flicker is produced by a moving shadow than when produced by stroboscopic illumination. Dark adaptation takes about 30 minutes. If the ventral region of the eye is illuminated, the threshold for the dorsal region of the eye is raised. The results are compared with those of previous workers and in the light of Autrums categories of slow and fast types of compound eye. Author
