I am not aware whether the structure cf the larynx has been carefully examined in these lower races of man; it probably pre sents differences from th- normal European of relatively little importance. But the brain we know to be very markedly simpler than that oi a European in tlie number of its con volutions, in the depth of the fissures, and complexity of pattern. In fact, the brain of some chimpanzees has been shown to be more complicated in this respect than that of some men (Hottentots and ether low races), and it may be that the fewness of distinct "vocal sounds" in some of the lower races Is related to this simplicity of brain. Who that has had a favourite dog, and has studied it with any sympathy and care, can deny that the varied sounds that it is able'to produce, limited in number though they' may be, are combined, and modulated so as to give expresaion to the emotions of the moment? The modifications of the bark _pe_kj to us of joy, playfulness, anger, or distress; the tone of the whine equally conveys a welcome, fretfulness, penitence, or .pain. From the growl we know at once whether the dog is angry or pleased. It is true that to our human ears the slight differences between some of the sounds es cape us, unless we are very familiar with the dog. We have to learn the "speech" in its details from Cadi new dog we have. But no less do we Europeans have to learn painfully the language of the more savage races.
