THE SPEECH OF MONKEYS. 97 



of the sooty Mangaby, but I have not been able 

 to record it sufficiently well to study. It is 

 one of the most peculiar sounds in the whole 

 range of simian speech. The phonetic elements 

 are nearly like "wuh-uh-uh," but the manner in 

 which it is delivered is very singular. It appears 

 to be intermixed with a peculiar clucking sound, 

 and each sound seems independent of the other, 

 although so closely joined in their utterance as 

 to sound almost like they were uttered simul- 

 taneously by separate means. It is a deep gut- 

 tural below the middle pitch of the human voice, 

 while the clucking element appears much higher 

 in pitch, and the whole sound is marked with a 

 strong tremolo effect. The syllables are uttered 

 in rapid succession, and this peculiar sound un- 

 der different conditions is uttered in at least 

 three different degrees of pitch at least an oc- 

 tave apart; but the contour appears to me the 

 same in each. This species talks but little, is 

 very shy, makes few friends, and is afraid of the 

 phonograph; hence I have never been able to 

 make a good record of its voice. I was cultivat-
