Abstract
II. WE have considered the main positions first taken up by Dr. Ferrier with regard to functional localisations, and it will be convenient to examine in the same order the criticisms and statements of other observers regarding those positions.

Dr. Ferrier is mistaken in supposing (vide p. 310) that the results of the experiments of Mr. Horsley and myself confirm his conclusions regarding the localisation of the auditory centre in the superior temporo-sphenoidal gyrus. The error seems to have arisen from the misunderstanding of a verbal communication. What we did find in one or two cases was that the whole of the temporo-sphenoidal lobe exclusive of the superior gyrus might be removed on both sides without loss of hearing—not the converse, that hearing was abolished on destroying only the superior gyri on both sides. Indeed, we did not in any single instance perform this last experiment.
Further on (p. 402) the author states that we have noted signs of stupidity in the monkeys m which we had removed the pre-frontal regions. I do not thmk, however, that such dullness as was exhibited in one or two of these cases was more marked or lasted longer than with equally extensive lesions of other parts of the brain.
