    to differentiate its subdivisions much more thoroughly than was possible in the case of the limb movements. Since in catching insects a quick play of mouth and tongue must be required, this may be an explanation of the large cortical representation of the tongue, mouth, and face. Stimulation of the occipital region gave wholly negative results, although this portion of the brain was well exposed and explored as thoroughly as possible with currents of the usual strength, as well as with currents which were some- what stronger. There is no doubt from histological examination that the Fig. 7.—Left Hemisphere of Marmoset. Mag. 3'5. F.S. Fissure of Sylvius. 1. Deviation of head and eyes to opposite side. 2. Opening of eyes. 3.

A similar negative result was obtained on stimulation of the corresponding region of the brain of the Lemur,* and in both cases this is probably due to the distance separating the solitary cells of Meynert in the parts stimulated. No portion of the cerebral cortex when stimulated give any movements of the external ear ; this is in striking contrast to what was found in the Lemur, * Mott and Halliburton, loc. cit., p. 140.
