![but one must not as yet penetrate into the choroid fissure and into the space under the corpus callosum. The connective tissue found here should for the present be left untouched. One is now in a position to see clearly the segmentation of the pallium. The lobes and the intralobular fissures, as well as the typical sulci and gyri, are now identified, one after the other. For better orientation, the more important fissures and sulci can be marked with an aniline pencil. One must not neglect to look at the gyri profundi hidden in the depth of the larger fissures (e.g., in the calcarine fissure). The next feature to be studied is the insula. In order to get a good view of F of i F l i Fig. C.—I.—III. are the cutting planes (see text). The dotted fields are the cross-sections of the long association bundles. F a, fasciculus arcuatus. F ci, F. cinguli. F l i, F. longit. infer. F of i, F. occipito-frontalis inferior (Curran). F sc, F. subcallosus (or occipito¬ frontalis [Forel] ). this, the overhanging opercula must be removed. First cut off the temporal operculum ; guided by the left fore-finger which has been inserted in the lower part of the circular sulcus, one pushes the knife in the direction as indicated in Fig. C (Cut II.) from the point of the temporal lobe backwards and then upwards against the posterior part of the fissure of Sylvius. In the same way the operculum frontale, and lastly the superior (Rolandic) operculum, are removed (Fig. C, Cut I. ; cf. also Plate II., Fig. 3). The three severed pieces can then be fastened, in their original position to one another by means of pointed pieces of wood (e.g., matches). The superficial formations of the rhinencephalon are all now open for inspection, except parts of the gyrus dentatus. The study of these must not be postponed, because later on various details can easily suffer.](https://iiif.wellcomecollection.org/image/b29813451_0024.jp2/full/800%2C/0/default.jpg)
