36 APES AND MONKEYS 



and found that some evinced fondness for the music, others 

 were indifferent to it, and a few showed aversion to it. It 

 appeared that the monkeys that were most attracted by 

 musical sounds enjoy the repetition of a single note rather 

 than the melody. It is possible that music, as we under- 

 stand it, is too high an order of sense culture for them. 

 The single note of a certain pitch seems to attract and 

 afford pleasure to some of them, but they do not seem to 

 appreciate rhythm or melody. 



As monkeys discern the larger of two pieces of food,

 enables them to appreciate dimension. As they are able 

 to discern singular from plural, and two from three or 

 more, they have, in that degree, the faculty of enumera- 

 tion. As they are able to distinguish and select colors, 

 they possess the first rudiment of art as dealing with color. 

 As they are attracted or repelled by musical sounds, they 

 may be said to possess the first rudiment of music. It 

 must not be understood, however, that any claim is made 

 that monkeys possess a high degree of mental culture ; but 

 it will be admitted that they possess the germs of mathe- 

 matics as dealing with form, dimension, and number ; of 

 art, as dealing with form and color ; of music, as dealing 

 with tone and time. It is not probable that they have any 

 names for any of these sensations, nor that they have any 

 abstract ideas that are not drawn directly from experience. 

 But as the concrete must precede the abstract in the 

 development of reason, it is more than probable that these 

 creatures now occupy a mental horizon such as man has 

 once passed through in the course of his evolution. It
