 very striking ones, manifested by the pelvis and 

 pelvic extremities, which I have cited in the 

 memoirs on the subject published in the Zoolo-

 and chimpanzee from the human species, must 

 stand in contravention of the hypothesis of trans- 

 mutation and progressive development, until the 

 supporters of that hypothesis are enabled to 

 adduce the facts and cases which demonstrate 

 the conditions of the modifications of such cha- 

 racters" 



I have been anxious to shew in a condensed 

 form the opinions upon this all-important subject 

 of the highest living authority; and no one can 

 read this book without thanking God that the 

 cause of Science and Truth is supported by a 

 pillar like that of Richard Owen a man whose 

 name will live long after the propounders of 

 unsound theories and hypotheses, unsupported 

 either by fact or scientific truth, shall have been 

 consigned to the same category of writers as those 

 who believed that geese were produced from 

 barnacles. 



I have given these extracts at length, because
