On their under side, a bridge ormass of white fibers runs from one to the other, andserves as a means of nervous communication be-tween them. The cere-brum is composed of bothwhite and gray matter, thelatter being spread overthe surface, and the formerfilling up the interior, andforming the greater por-tion of the mass (Fig. 59).The arrangement ofthe nerve-matter of thecerebrum is very peculiar.It is formed into folds andwrinkles, somewhat likethe meat of an Englishwalnut. These folds arecalled the convolutions ofthe brain, and, as the graymatter follows closely thedipping of the surface be-tween the convolutions, itis evident that the amountof gray matter is muchSfreater than it would beif the surface of the brainwere smooth.It has been found by experiment that the nerve-matter composing the cerebrum is insensible to
