Well conducted experiments upon animals are pecu-liarly needed and suitable for throwing light upon thisobscure problem as to the possible localization of ^perceptivecentres in the Hemispheres, because when numeroustrials, as to the effects of local stimulation or destructionof different regions of the Hemisphere, may have enabledthe experimenter to fix upon some portion of the cortex asthe main seat of one of such centres, it is then in his Chap.
