The white-faced Cebus always has a languid expression, and looks like some poor, decrepit old man, who has borne a great burden of care through a long life, and finds his toil and patience ill-requited and is now awaiting his last call. He always has a sad face, and looks as if his friends were false. His type of speech is very far inferior to that of the Capuchin, and I do not regard him as a good subject for my work. [Sidenote: JIM AND THE MANGABY] I have learned the food sound in the dialect of the sooty Mangaby, but I have not been able to record it sufficiently well to study; but it is one of the most peculiar sounds in the whole range of Simian speech. The phonetic elements are nearly like "wuh-uh-uh," but the manner in which it is delivered is very singular. It appears to be intermixed with a peculiar clucking sound, and each sound seems independent of the other, although so closely joined in their utterance as to sound almost like they were uttered simultaneously by separate means. It is a deep guttural, below the middle pitch of the human voice, while the clucking element appears much higher in pitch, and the whole sound is marked with a strong tremolo effect. The syllables are uttered in rapid succession, and this peculiar sound under different conditions is uttered in at least three different degrees of pitch about an octave apart, but the contour appears to me the same in each. This species talks but little, is very shy, makes few friends, and is afraid of the phonograph; hence I have never been able to make a good record of its voice. I was cultivating the friendship of Jim, who recently died in Central Park, and we were getting on the best of terms; but the little Mangaby that survives him is very shy and suspicious. Immediately after Jim's death, however, when I would visit the Garden, she would always jump on the perch and take the same position that Jim had occupied whenever I would feed him. During his lifetime, she always kept her distance and never would take anything out of my hand, because she was afraid of him; but as soon as he was out of the way she assumed his place, and would utter the same sound that he had uttered at my approach. She evidently was aware of the fact that Jim and I were friends, that I always gave him something good to eat at that particular place in the cage, and that he always sat in a certain position when I gave it to him. I do not regard this species as very intelligent, nor their language as being of a high type; but they have a very human-like face, almost without hair, and very large and expressive eyes. They abound in West Africa, and have been colonised with success in the island of Mauritius; they are not very common in captivity, but much more so than some other species of less interest.
