ORDER QUADRUMANA. 273 



quently, and shall have more frequent occasions to do so, 

 through a large portion of this work, for to him we are in- 

 debted for the most minute and interesting researches on 

 the mammalia, mentions that subsequently to his examina- 

 tion of the Mone, two other quadrumana of the Guenon 

 family presented themselves to his notice, possessing moral 

 characteristics precisely similar. They exhibit the most 

 perfect confidence and affection for such as treated them 

 well, a gentle familiarity, no malice, and still less any irre- 

 gular desires, in short it was impossible to behold any 

 animals more amiable or more amusing, one of these was 

 the Ascagne, or long-nosed monkey, the other the Hocheur, 

 or vaulting monkey. 



This resemblance of character induced our naturalist to 

 pay more attention to the organization of these animals, 

 than he had hitherto done, for he justly deemed it impossi- 

 ble, that there should be so much difference between their 

 disposition, and that of the Guenons which we have pre- 

 cedently described, without some corresponding traces in 

 their physical structure, some external symbols of this in- 

 ternal character. And here let us remark once for all, that 

 this doctrine of mental and corporeal correspondencies, 

 whether in man or other animals, does by no means mili- 

 tate against the most approved and orthodox opinions on 

 the subject, of mind and matter. Notwithstanding the 

 assertion of some acute philosophers, the constant conjunc- 

 tion of two phenomena, does not always prove that one is 

 the cause of the other. There may be something else, hid- 

 den from our inspection, which is the true cause. Thus, if 

 well-developed cerebral hemispheres be found invariably to 

 accompany mental superiority, we have no reason necessarily 

 to believe that such development is the cause of such supe- 

 riority. All that we have a right to infer, is, that a supe- 

 rior mind requires an instrument of superior construction.
