Il6 APES AND MONKEYS 



regard as the climax of all my efforts in the study or 

 training of apes, and that is the fact that I succeeded in 

 teaching him one word of human speech. This alone is 

 sufficient to demonstrate that the animal has within him 

 the resources of speech. 



In conclusion I again assert that the sounds uttered by 

 these apes have the characteristics of human speech. The 

 speaker is conscious of the meaning of the sound used. 

 The pitch and volume of the voice are regulated to suit 

 the condition under which it is used. The ape knows the 

 value of sound as a medium of conveying thought. These 

 and many other facts show that their sounds are truly 

 speech. 



To compare the mental faculties of the wild ape to the 

 domesticated dog is not a fair standard bv which to meas- 

 ure their respective abilities. The dog has acquired much 

 by his long and intimate association with man. If the ape 

 were placed under domestication, and kept there as long 

 as the clog has been, he would be as far superior to the 

 dog in point of sagacity as he is by nature above the wild 

 progenitors of the canine race.
