Abstract
Dissection of the foot of an adult [female] highland gorilla (G. beringei) reveals the fact that the foot musculature of this animal does not differ from that of the lowland gorilla (G. gorilla). The arrangements of the various muscles in this G. beringei, in most of the significant characters, fall within the known range of variation of G. gorilla. The individual muscles of the gorilla foot are compared with those of other primates. The musculature of the gorilla foot, on an average, makes a closer approach to that of man than does the foot musculature of any other primate. This is apparently a convergence caused by the mode of life of the gorilla.
