208 ANTHROPOID APES. 



that there is the most complete agreement between 

 men and animals with respect to the relations 

 of the vertebral column to the peripheral nervous 

 system. According to this author, man, from the 

 anatomical point of view, stands so completely within 

 the class of anthropoids, that the attempt to assign 

 to him any other place in zoology is open to the 

 charge of being biassed by considerations which 

 have nothing to do with facts.* 



The organs of the senses in anthropoids do not 

 present any noteworthy points of difference from 

 these organs in man. I have written, but not yet 

 published, a treatise on the eyes of these animals, 

 showing their general agreement with the conditions 

 of the human eye. On the skin of the lingers and 

 toes of anthropoids developed corpuscles may be 

 detected which are connected with the sense of 

 touch. 



The vascular system of anthropoids has not up to 

 this time been studied in any exhaustive manner. 

 The heart strongly resembles that organ in man. In 

 the gorilla, the chimpanzee, and the orang the great 

 arterial branches have the same relative conditions 

 as in the human organism. A common origin from 

 one branch of the subclavian artery, and of ,the 

 right and left carotid arteries, often occurs in the 

 orang and with a certain constancy in the gibbon, so 

 far as we can judge from the researc-hes which have 

 been made up to this time. But we know that this 

 form of deviation from the common type is not
