![mcater; nor does it cover them loosely, but it makes its way deeply into every cavity and every recess, and there it presses around and closely invests them (p. 7). The shape of the cerebrum, especially with man, is somewhat globular or spheri- cal. Its outer surface is everywhere marked by gyres and winding clefts, which are similar to the convolutions of the intestines. Each convolution, or the whole body of the cerebrum, consists of two substances, namely, the cortical, which is of an ashy colour and is outermost, and the medullary, which is underneath the other, and presents a whitish appearance. The cerebnim, which by these tortuous windings is almost ploughed through by furrows or sulci, is cleft in the middle, and as it were divided into two hemispheres. Both, however, are joined m the middle, and repose there as it were on a very white sub- stance similar to that which lines the whole mass of the cerebrum interiorly, and as it were constitutes its vault. This substance [the corpus callosum] is harder than any other portion of the bram; since it is entirely medullary in its character, and is the recipient of the medulla of all the convolutions, and serves them m the place of a common base. This corpus callosum or this medullary substance, near the anterior parts of each hemi- sphere of the cerebrum, is thicker and denser than in any other place; and there it is attached on both sides to the medulla oblongata by apices or protrusions. From these apices, which are m a certain seuse its origin, this medullary substance which lines and vaults the cerebrum extends towards the back, and diminishes gradually in thickness; at last the outer border of this expanse is drawn more closely together and is conjoined underneath with the body of the medulla oblongata by fastenings consisting of membranes and vessels. In order to strengthen this connection, a medullary process [the fornix] takes its origin at the anterior part of the corpus callosum near its apices or protrusions • this extends under the fissure of the cerebrum and passes to the extremity of the above body and to this it is attached by two arms as it were stretching back; these same arms embrace the body of the medulla](https://iiif.wellcomecollection.org/image/b21292991_0001_0055.jp2/full/800%2C/0/default.jpg)
