RECORDS OF LIONS
The records of the lions show some strange features in the construction of sound; and when analysed on the phonograph present some novel effects. The sound as a whole appears to be broken into broad waves or pulsations; but on analysing it the fundamental tones somewhat resemble the sounds produced by drawing a mallet rapidly across the keyboard of a xylophone, and are characterised by a peculiar resonance something like the tremulous vibrations of a thin glass containing a small quantity of water. Each of these separate fundamental sounds, or sound units as they appear to be, can be further reduced to still smaller vibrations; and the result suggests that the fundamental sounds themselves are an aggregation of smaller vibrations. I have not as yet been able to compare the notes one by one with the scale of the xylophone in order to ascertain whether or not they obey the laws of sound upon which is founded the chromatic scale of music. The lion makes only a small number of different sounds, nearly of the same pitch. I have not analysed the vocal sounds of the other felines to ascertain to what extent they coincide with those of the lion; but his appear to be somewhat unlike any other sounds which I have examined.
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.
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.
