MAN AND APES. 95 



hibits in most apes certain bony prominences,* 

 which are rudimentary in man. The three 

 highest genera resemble man in this respect, 

 but the same resemblance is found in the 

 Slender Lemur (Lor is) and in closely allied 

 forms. 



The sacrum f of man (Fig. 51, b) is also 

 nearly as much resembled (size not being con- 

 sidered) by that of Loins as by those of the 

 highest apes. Again, in the angle which this 

 bone forms with the lumbar part of the back- 

 bone, man is most resembled, not by the 

 highest apes, but by some Baboons. The 

 same may be said respecting the concavity 

 of the anterior surface of the sacrum ; and of 

 the three highest genera it is not the Gorilla 

 and Chimpanzee which resemble man most 

 nearly, but the Orang. 



The hinder aspect of the back-bone exhibits 



* Termed " Metapophyses " and " Anapophyses." For 

 details as to these see 'Pro. Zool. Soc.' 1854, pp. 

 571-576. 



•f The " sacrum " is the large and solid piece of the 

 back-bone to which the haunch-bones are attached.
