ZOOLOGICAL GARDENS—LOISEL. 427 
David’s deer (Hlaphurus davidianus), that produced 38, and finally, 
if we note that these numerous births enable the Duke to enrich each 
year the collections of the zoological gardens of England, and even 
that of our Jardin des Plantes, we may say with perfect truth that 
not only does acclimation but zoology proper owe much to the presi- 
dent of the Zoological Society of London and to the Duchess of Bed- 
ford, who also interests herself with intelligence and activity in the 
work going on at Woburn. 
Tring Park.—The origin of the zoological collections at Tring 
Park goes back some thirty years at the time of the youth of Sir 
Lionel Walter Rothschild, eldest son of the great English banker. 
When quite a child Lionel Walter loved to collect butterflies and birds 
that he found in abundance upon the large estate that his father pos- 
sessed at Tring, and which he also procured by purchase. His col- 
lections gradually increased to such proportions that he conceived the 
idea of establishing at Tring a great scientific establishment now 
known as the Museum; at the same time be made some experiments 
in acclimation in the park of the chateau and at Dundale, one of its 
dependencies. . 
Dundale is a small estate situated a few minutes walk from the 
Museum; there is there a small park with a large pond where a cer- 
tain number of webfooted birds breed every year. Many hybrids 
have been thus obtained, as well as melanistic and albino individuals. 
He has never had there, however, a regular station for experimental 
zoology, as I had supposed, and when I was there it was with difli- 
culty that I could discover a few ducks swimming about in the clear 
water among aquatic plants. 
The animals that feed upon the extensive undulating plain in front 
of the park of the chateau of Tring are lhkewise not placed there for 
the purposes of study. There is there a flock of 17 emus (Dromaeus 
and another of 15 rheas (Rhea americana and darwinii), that, im- 
pelled by curiosity, came forward to meet me when I entered the 
park. Farther on (pl. 1v) I met, at the edge of a pond, some soli- 
tary emus and, on the right, in a slight hollow, a herd of kangaroos, 
that, sitting up in order to examine me better, allowed me to approach 
near enough to photograph them; I recognized the great kangaroo 
(Macropus giganteus), which thrives extremely well on the grassy 
plains of the park, and Bennett’s kangaroo (M/. Halmaturus Ben- 
netti), which especially affects the wooded portions. Continuing my 
walk, I perceived at a distance a herd, comprising about 150 head, of 
Japanese deer (Cervus sika) and fallow deer. Finally, going toward 
the forest that bounds the park on one side, I reached an inclosure 
where was an ostrich with its young and a large pheasantry where
