 of similar value to that of Tyson on the Chim- 

 panzee. He dissected several females and a male, 

 all of which, from the state of their skeleton and 

 their dentition, he justly supposes to have been 

 young. However, judging by the analogy of man, 

 he concludes that they could not have exceeded
