208 Address delivered at the sixth and last 



extraordinary success of these works has proved the good 

 effect of this judicious union. The principle of " gratior 

 pulchro veniens in corpore viiius " * was never more strongly 

 exemplified than in those popular publications. From among 

 the various species touched upon in these works I shall select 

 two, which, although long since named in science, have 

 assumed under his hand an original form. The first is the 

 Mus Barbarus of Linnaeus, a species hitherto almost doubtful, 

 but now assuming a certain and legitimate rank among the 

 true ikf ures ; the second the Chinchilla f , an animal familiar 

 to us by reputation, but a personal stranger, until introduced 

 by his accurate delineations. To Mr. Bennett, also, we are 

 indebted for the valuable analysis of works on zoology which 

 have appeared in the Zoological JournaL A sense of justice 

 compels me to add, that the credit which may belong to the 

 general superintendence of that work should attach to him. 

 My name, by the kind partiality of my friends, stands at the 

 head of the publication ; — the merit is solely his. 



While referring to the additional information on the subject 

 of the Mammalia, supplied within the last year, I must name 

 another of our colleagues, Mr. Yarrell, whose researches into 

 the comparative anatomy and physiology of animals have 

 already secured for him the highest rank in science. Here, 

 again, the beneficial agency of our Zoological Club is strongly 

 conspicuous. To its influence we are mainly indebted for the 

 public services of Mr. Yarrell. His knowledge and his acUmen 

 are his own : but we are proud in the reflection that it was the 

 incitement ^d example afforded by this club that first induced 

 him to exert these qualities in public. You may judge of the 

 value of this influence by the fruits it has produced. I refer 

 to the reports of our former chairmen for his labours in for- 

 mer years. Within the year of my presidency he has given 

 us a continued series of erudite observations on the osteology 

 and internal structure of the animals which have died in the 

 menagerie of the Zoological Socfety. If in all of these there 

 should be no new contribution to science, there is ample con- 

 firmation and beautiful illustration of the knowledge already 

 possessed. 1 cannot here pass over without praise the share 

 which another able recruit to zoology has taken in these inves- 

 tigations. From Mr. Holberton, who has for the most part 

 cooperated with Mr. Yarrell in his examination of the before- 

 mentioned subjects, much valuable instruction has already 

 been derived, and much more may confidently be expected. 



* " Worth more pleasing in a lovely form." 



f The anrnial is chatacterised by Mr. Bennett under the name of Chin* 

 chilla lanlgera.
