Of course this failure was due to poor Suzette's artificial life, and unnatural surroundings. Had she been all alone, in the depths of a tropical forest, Nature would have proceeded along her usual lines. But in our Primate House, Suzette felt that her infant was surrounded by a host of strange enemies, from whom it must be strongly and persistently _guarded and defended._ That was the idea that completely dominated her mind, ruled out all human help, and blocked the main process of nature. During the eight days that the infant lived, it was able to reach her breast and nurse only once, for about one minute; and then back it went to its prison, where it died from sheer lack of nourishment. In 1920, that same history was repeated, except that on this occasion our Veterinary Surgeon, Dr. W. Reid Blair, worked (on the fifth day) for seven hours without intermission to stupefy Suzette with chloroform, or other opiates, sufficiently to make it possible to remove the baby without a fight with the mother and its certain death. Owing to her savage temper all the work had to be done between iron bars, to keep from losing hands or arms, and the handicap on the human hand was too great. Even when Suzette had received chloroform for an hour and twenty minutes, and was regarded as _half dead,_ at the first touch of a human finger upon her thigh she instantly aroused and sprang up, raging and ready for battle. The whole effort failed. To rope Suzette and attempt to control her by force would have been sheer folly, or worse. In such a struggle the infant would have been torn to pieces. The second one died as the first one did, and for an awful week we were unable to gain possession of the decomposing cadaver. Suzette knew that something was wrong, and she realized the awful odor, but that idea of defense of her offspring obscured all others. In maintaining her possession of that infant, nothing could surpass the cunning of that ape mother. Will we ever succeed in outwitting her, and in getting one of her babies alive into a baby incubator? Who can say? X THE TRUE MENTAL STATUS OF THE GORILLA The true mental status of the gorilla was discovered in 1919 and 1920, at 15 Sloane Street, London, by Major Rupert Penny, of the Royal Air Service, and his young relative, Miss Alyse Cunningham. Prior to that time, through various combinations of retarding circumstances, no living gorilla had ever been placed and kept in an environment calculated to develop and display the real mental calibre of the gorilla mind. It seems that an exhibition cage, in a zoological park or garden thronged with visitors, actually tends to the suppression, or even the complete extinguishment, of true gorilla character. The atmosphere of the footlights and the stage in which the chimpanzee delights and thrives is to the gorilla repulsive and unbearable.
