Dodo had a bright face and a symmetrical figure. In her I witnessed one of the most interesting acts that I have ever seen in any monkey. Her combined speech and actions bordered on the histrionic. Her monologue was addressed to her keeper, of whom she was especially fond. At almost any hour of the day Dodo would stand erect and deliver to her keeper the most touching and impassioned address. The keeper went into the cage with me, to see if he could handle her. After a little coaxing she allowed him to take her into his arms. After he had caressed her for a while and assured her that no harm was meant, she put her slender little arms about his neck and like an injured child cuddled her head up under his chin. She caressed him by licking his cheeks, and chattered in a voice full of sympathy. Her display of affection was worthy of a human being. During most of this time she continued her pathetic speech. She was not willing he should leave her. The only time at which she made any show of anger or threatened me with assault was when I attempted to lay hands on her keeper or to release him from her embrace. At such times she would fly at me and attempt to tear my clothes off. On these occasions she would not allow any other inmate of the cage to approach him or to receive his caresses. The sounds which she uttered were at times pitiful, and the tale she told seemed to be full of sorrow. I have not, so far, been able to translate these sounds, but their import cannot be misunderstood. Her speech was doubtless a complaint against the other monkeys in the cage, and she was probably begging her keeper not to leave her alone in that great iron prison with all those big, bad monkeys who were so cruel to her. One reason for believing this to be the nature of her speech is that in all cases where I have heard this kind of speech and seen these gestures, the conditions were such as to indicate that such was their nature. It looks, however, very much like a love-making scene of the most intense kind.
