Anatomy of the Brain

hiatus internally, p. 17. In the anatomy of the brain, one must begin from its posterior limb, which, the connection of the membranes having been loosened, should be separated from the contiguous parts and raised forward, so that the empty space held for the ventricles may be uncovered, p. 18, and the crura of the medulla and the fornix may appear. Under this position of the brain, whatever it has outside or inside is seen, ibid. Outside, its anfractuosities, two hemispheres, and likewise a double substance, viz. cortical and medullary, are discerned, p. 20; inside, the corpus callosum and the three-sided fornix occur, p. 21. The limb of the brain having been cut from the sides, and its structure further reclined, the whole interior surface may be unfolded and projected as it were onto a plane, p. 22. The apices of the crura of the medulla oblongata, by which the brain is tied, are the corpora striata, p. 23. Two figures, by which the base of both the human and the sheep's brain is represented, are explained, p. 25 to 28.

Chap. II. The medulla oblongata and the other posterior parts of the encephalon are reviewed, and their dissection is handed down, p. 29.

The corpora striata with their transverse process are described, 30. The thalami of the optic nerves and their medullary processes, 31. The orbicular prominences, called nates and testes, ibid. These are not the crura of the cerebrum and cerebellum, 33. The posterior ones, or testes, are only epiphyses of the former, ibid. from which also through medullary processes...
