Base view. ecu. shallow longitudinal depression marks off, in some birds, a medianfrom a lateral tract of the upper surface of the hemisphere: inmost this surface is uniformly convex. The hemispheres presentan undulate surface below; the medial parts being in some birds ANATOMY OE Dissected brain of a Pigeon. XXXIV. cerebral ganglion is produced, so as to cause a concavity transversely between themand the lateral borders, as shown in fig. 44. On the lowerpart of the side of each hemisphere there is a depression whichcorresponds to the fissura magna Sylvii, and affords the soleindication of a division into lobes. The hemispheres are con-nected together by means of the round commissure, fig. 45, mesial surfaces of the hemispheres, which are in contactwith each other, present striae which divergefrom the commissure. These surfaces arecomposed of an extremely thin layer of medul-lary substance, fig. 45, f, rj, forming the in-ternal parietes of the ventricle, and extendedoutwardly over the corpus striatum, ib. its homologue in liept ilia and the mam-malian embryo, it does not present the alter-nate striae of grey and white matter, whichsuggested its name in Anthropotomy.
