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 virtus” * 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 
Mis Barbarus of Linneeus, a species hitherto almost doubtful, 
but now assuming a certain and legitimate rank among the 
true Mures; the “second the Chinchilla +, 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 super jitenidénee 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 researchés into 
the comparative anatomy and physiology of animals hay 
already secured for him the highest rank in science. rive; 
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 and 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 produc ‘ed. 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 Society. If in all of these there 
should be no new contribution to science, there is ample con- 
firmation and beautiful illustration of the knowledge e already 
possessed. I 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 eee be expected. 
* “« Worth more pleasing in a lovely form.’ 
+ The animal is characterised by Mr. Bennett under the name of Chix- 
chilla \anigera.
