110 THE SPEECH OF MONKEYS.

 with that of Professor Huxley, who assigns the 

 gorilla the highest place next to man in the order 

 of nature, and the chimpanzee next below him. 

 I shall not here attempt to discuss the question 

 with so high an authority, and I must confess 

 that the vocal index is not yet so well defined 

 that it may be relied upon in classifying apes. 

 One aim I have in view is to study the gorilla 

 and chimpanzee side by side in their native 

 wilds, and to record if possible the sounds of 

 their voices in a wild state. From the study 

 I have made of the sounds, I feel confident that 

 all the vocal sounds made by these apes may be 

 uttered by the human vocal organs. 



Some months ago I made a record of the voice 

 of the great Anubis baboon, in Philadelphia. I 

 did not expect to find in him an elevated tpye of 

 speech, but my purpose was to compare it with 

 other simian sounds, to see if I could not estab-

 sounds that would coincide with certain other 

 characters. I had found, by the study of certain 

 cranial forms, that certain vocal types conformed 

 to certain skulls, and were as much a conforma- 

 tion thereof as are the cerebral hemispheres. I
