Observations on the physiology of the cerebral cortex of the anthropoid apes

Abstract

Since presenting our former note on this subject, we have obtained some further observations, though the number is still less than we should wish, owing to the rarity and expense of the material. Our further observations have been upon five chimpanzees of the commoner variety, and upon one more orang. The statements given in our former communication have been confirmed in all respects by our observations obtained since then.
