Among the few sounds of birds which I have analysed, I may mention the Trumpeter Crane. I have made one record of this bird which was sufficiently loud to enable me to obtain some idea of the character of the sound. I am in doubt as to what the real mode of producing this sound is. The volume of sound evidently comes from the mouth of the bird; but while in the act of making it, he appears to bring the whole body into use, even the feathers appear to take some part in its production, and the whole frame of the bird vibrates in the act. The record which I have shows some resemblance, on analysis, to the sound made by the lion; but it is not sufficiently strong to admit of analysing the sound units or fundamental sounds. [Sidenote: DIFFERENCE IN PHONES OF GENERA] From the many sounds that I have analysed, it appears to me that there is a difference in the phones of all different genera, and that the phonetic basis of human speech more closely resembles that of the Simian than any other sounds; but I wish to be understood distinctly not to offer this in evidence to establish any physical, mental, or phonetic affinity between mankind and Simians. I merely state the facts from which all theorists may deduce their own conclusions. CHAPTER XIV. Monkeys and the Mirror--Some of their Antics--Baby Macaque and her Papa--Some other Monkeys. I have incidentally mentioned elsewhere the use of the mirror in some of my experiments, but I have not described in detail how it affected various monkeys. Of course, it does not always affect the same monkey in the same way at different times, nor does it affect all monkeys of the same species in exactly the same way, and therefore I cannot deduce a rule from my experiments by which the species can be determined by its conduct before the glass. [Sidenote: PUCK AND NELLIE WITH MIRROR] When Puck saw himself in the mirror he undoubtedly mistook the image for another monkey, to which he would talk more freely than he would to the sounds made by the phonograph. He would frequently caress the image, and show signs of friendship; at the same time he was very timid and retiring. Nellie would chatter to herself in the mirror, and seemed never to tire of looking at that beautiful monkey she saw there, and I do not think the propensity could be accounted for merely by her sex. I do not think she ever quite understood where that monkey was concealed, and the scores of times in a day that she would turn the glass around was evidence that she never fully despaired of finding it.
