Thecerebellum and corpora quadrigemina are not covered bythe cerebrum, and the tentorium extends upwards andbackwards to the vault of the cranium. The brain wasthen removed. The olfactory nerves were entirely absent. There wasno foramen present for them. Fig. Specimen No. 2. Human cyclops showing the base of the skull andcranial nerves (note the single optic nex*ve). Tin optic nerves were single and arose from a processof brain which ran down to the optic foramen. No optic-tracts could be made out. The rest of the cranial nerveswere double and in their normal position. There weretwo ophthalmic arteries passing through the foramen oneither side of the nerve.
