In man,(jn the other hand, the parts of the brain corresponding to the optic lobes of the frog do not represent a locality in which such connections are established, so that in him the hemispheres alone do the work which in the less specialised form may be performed by the lower centres. In this connection we naturally inquire how the cerebral hemispheres may have acquired in the higher vertebrates capabilities which belong to them in a less and less degree as we descend from man through the zo...ological scale. In the higher forms it appears that the incoming impulses, instead of passing over in the primary centres to cells which discharge downwards, pass to a group of afferent central cells which carr)' impulses to the cortex, that with the organisation of this second j^athway the first liecomes less passable, and thus the function is transferred, though the causes determining the growth of the central cells on which the change depends are still obscure. One difficult)' felt by all who have touched this problem of localisation is due to the very large portion of the encephalon, especially in the cerebrum, to which our observations and conclusions have not )'et been applied.
