EVOLUTION OF SPEECH 



they were able to communicate their wants in some 

 manner to each other. 



The Chimpanzees and onrang outangs, though 

 more human-like in size, have less power of vocal ut- 

 terance than the Gibbons ; the Hylobates Lar possess 

 loud and powerful voices, but their utterances are 

 those of musical intervals, not articulate sounds. The 

 efforts of R. L. Garner, K Y., 1892, to interpret the 

 vocal sounds made by the above species into language 

 indicative of their emotions or their their wants, and 

 to repeat the same to them again by means of the 

 phonograph, have failed so far of success. The 

 Hanuman (Semnopithecus) or Sacred Monkey of the 

 Hindoos, as well as the Hylobates above-mentioned, 

 though smaller and differing widely from the human 

 form, yet possess a higher order of intelligence than 

 those of the races Gorilla, Chimpanzee, etc., who out- 

 wardly nearer approach to man. In the Gorilla, 

 especially, it would seem as if the process of evolution 

 had expended itself in developing the perfection of 

 muscular strength at the expense of all other physical 

 and mental attributes. 



With, the development of speech the existence of 

 true man (Homo Sapiens) began. Language at first 

 probably consisted of ejaculations only, possibly 

 such as his progenitors had possessed, but now used 

 and understood in a definite and restricted sense.
