β¦ Synopsis
This expedition was orgauized by
Mr. H. J. Coolidge. The Carnegie Institution of Washington coiitributed a grant toward the author's expenses on this trip. Body weight and size of eye were determined on the freshly shot specimens in the field, the size of the orbit, naturally, only after the skeleton had been thoroughly cleaned at home. 'In the juvenile gorilla this proportion amounts to 38.6, i.e., to practically the same as in a juvenile chimpanzee of the same stage of dental development. Since, as discussed below, this index always decreases markedly with advancing age, it is safe to msume that the eye-orbit index of adult gorilla does not differ radically from that of adult chimpanzee.
