This seriesof wiiidings or convolutiolzs appears quite decidedlyin the brain of the cat, in a mannervery similar in the brain of the dog, and withstill greater beauty and amplitude of fold inthe brain of the horse. This folding processwhich is resorted to in the case of all thehigher quadrupeds, seems a contrivance bywhich it is possible to pack a greater amountof material in such a way as to expose agreater degree of surface, within the liarrowspace at command inside the cmnium. In allthe three examples named, great prominence
