On the proportions between some areas of the first cervical segment of the spinal cord of primates.

It has been generally supposed that the dorsal funiculi occupy a relatively larger part of the highest segments of the spinal cord in man than in any other primate. We have taken planimetric measurements of the total area of the cord, dorsal funiculi, and total gray in the uppermost segments of the spinal cord of a wide variety of primates. Our results indicate that the largest values for the proportions dorsal funiculi/total white matter and dorsal funiculi/ventrolateral funiculi are found in gorilla, chimpanzee, and orang, rather than in man.

Cranial capacity of Oreopithecus bambolii.

From a plaster reconstruction of the skull of the August 1958 skeleton, the cranial capacity of Oreopithecus bambolii has been estimated as fallingbetween 276 and 529 cubic centimeters, thus within the ranges of variation of both orangutan and chimpanzee. In cranial capacity, therefore, and probably in body-brain ratio as well, Oreopithecus is a hominoid.
