OF all the wild animals that enchanted our youthful 'imagination, the gorilla is the most impressive ; and rightly so, for he is both monstrous and mysterious. His ferocity and his elusiveness make him harder to study than almost any other beast. During the past eighteen months Mr. Neville Sharp found himself, as an official of the Government of Nigeria, posted'to a portion of the mandated territory of the Cameroons, where he was frequently without a white man to talk to for weeks at a time. Happily, he found a hobby ready to hand in the gorilla, of whose habits he made a detailed and adventurous study, one by-product of which is a collection of skulls which is perhaps unique in Europe.
