Anatomy of the Brain

Chap. V. The brains of birds and fish are described, p. 66.

The brains of humans and quadrupeds are similar, and exist as if symbols, and so also are those of birds and fish, 66. In birds, the dura meninx has four sinuses, 67. The pia meninx, being very thin, is marked by fewer vessels, 68. In the brain, the anfractuosities, corpus callosum, fornix, and corpora striata are missing; but their duties are supplied by other bodies, ibid. Two cavities covered with striated membranes, 69. In these, the figure of the brain, with respect to its shape in man, is inverted, 70. In the medulla oblongata, two notable protuberances with a subject cavity are present, 71. From the excavated prominences a fissure leads to the infundibulum, 72. In these, the carotid arteries, and likewise the mammillary processes and the cribriform bone are present, 73. The conformation of the cerebellum is the same in these as in other animals, 74. The brains of fish are similar to those of birds, 75. They are furnished with an organ of smell, 76.

Chap. VI. Concerning the offices of the brain and its parts; where primarily it is discoursed upon the uses of the cranium and the dura meninx, p. 77.

The cranium is in the place of both a barrier and a defense for all animals, 78; wherefore it is endowed with furrows and inequalities, 79. Its figure in quadrupeds is depressed...
