The connec-tion between the nerves is of the same description asin the former instance. I am tempted to add a figure of the origins of thecerebral nerves, as they appear when made out inthe substance of a brain hardened in alcohol. It willserve to illustrate several of the remarks which I havealready had occasion to make, and I shall again findadvantage in having it to refer to. 342 Plate of the Origins. A. Represents the under part of the corpus striatum. B. The thalamus nervi optici. C. The corpus geniculatum externum. D. The corpus geniculatum internum. Of the Cerebral Nerves. 343 E. The corpus bigeniinum superius. F. The corpus bigeniinum inferius. G. The exterior stratum of the crus cerebri cutthrough so as to show the distribution of H. The upper pedicle of the cerebellum. I. The pons Varolii cut through at the part wherethe fifth nerve perforates it. K. The corpus restiforme. L, The corpus olivare. M, The anterior pyramid: the letter is placed justabove the decussation of the pyramids. The nerves are marked with the numbers whichdesignate them: it is only necessary to observe, that5a, represents the larger portion of the fifth with theganglion of Gasser; and 5b, the smaller portion^ which,passing below the ganglion, afterwards forms part ofthe third division of the fifth; that 7a, is the portiodura, 7b, the portio mollis of the seventh, I believe that the observation will be fo
