It is only in the Mammals that the diaphragm forms a transverse partition of the body-cavity, completely separating the pectoral from the abdominal cavity. N nostrils, NA nasal bone, Mx upper jaw, Prf prefrontal, Fr frontal bone, A eye-pits, S temple-pits.
This connexion is due to a growth from the prefrontal backwards to join a process of the frontal, and is entirely absent in symmetrical fishes. It is along this bony bridge that the dorsal fin extends. The origin of the eye muscles and of the optic nerves is morphologically the same as in symmetrical fishes.
The brain weighed 1390 grams and showed little or no gross lesion, if we except a pigmentation of the right prefrontal region under an area of old pias hemorrhage. There was also a chronic leptomeningitis, with numerous streaks and flecks along the sulci, especially in the frontal region.
"If the magter's total brain were smaller in volume than normal it could fit into the remaining space in the cranial hollow. But the brain is full-sized it is just that part of it is missing, absorbed by the symbiote." "The frontal lobes," Brion said with sudden realization. "This hellish growth has performed a prefrontal lobotomy!"
