One of the most remarkable things I have ever observed among monkeys was done by this little fellow. On two separate occasions I have seen him apologise to Dodo in the most humble manner for something he had done, and I tried very hard to secure a record of this particular speech, in which I totally failed, as I could not foreknow when such an act would be done, and therefore could not have my phonograph in place to obtain such a record. I called the attention of Mr. F. S. Church, the eminent artist, to this act, with the hope that he might be able to make a sketch of Nemo while in this attitude. I do not know what the offence was, but the pose and expression as well as the speech were very impressive. He sat in a crouching position, with the left hand clasping the right wrist, and delivered his speech in a most energetic but humble manner. The expression on his face could not be misunderstood. After a few moments he paused briefly, and then seemed to repeat the same thing some two or three times. The manner of his delivery was very suggestive, and his demeanour was conciliatory. When he had quite finished his speech, Dodo, to whom the apology was being made, and who had listened to it in perfect silence, delivered a sound blow with her right hand on the left side of the face of the little penitent, to which he responded with a soft cry, while Dodo turned and left him without further debate. I also called the attention of the keeper to this act, and he assured me that he had repeatedly witnessed the same. What the subject of his speech was or the cause which brought it about I am not able to say, nor can I say with certainty to what extent he explained, but that it was an apology, or explanation of some kind at least, I have not the slightest doubt. I do not believe, of course, that his speech contained any details concerning the offence, but that it expressed regret, penitence, or submission does not to my mind admit of a doubt. I have seen a few other cases somewhat similar to this, but none of them comparing in point of polish and pathos to that of Nemo in his unique little speech.
