the accommodation of visitors; an artificial lake 8 acres in extent 
and on which are likewise two steamers and numerous pleasure boats; 
kitchen gardens and pleasure gardens, nurseries, a toboggan slide, 
conservatories, ete. 
In the midst of such diverse attractions as these are found the 200 
cages, yards, or pools of the menagerie in which are daily fed nearly 
1,000 animals (250 mammals, 600 birds, and 60 reptiles), some of 
which merit our attention. 
The monkey house in particular is perhaps the finest one now ex- 
isting in the gardens of Europe. It is a large structure of Moorish 
style, widely hghted and ventilated from above and from the whole 
of the western side, but not heated throughout during winter. It 
contains first a large central cage, 27 meters long by 5.50 meters wide, 
in which there are some fifty monkeys, principally baboons and 
macaques. As a peculiarity of this cage I noted the presence of 
various playthings which seemed to me very useful for satisfying the 
need for movement and intellectual activity of the animals; there 
were rattles, bells, rocking horses, trapezes, balancing poles, hang- 
ing ropes, a large wheel and turntables, a pigeon house and a well 
with a pump, by means of which the monkeys could draw water for 
themselves, a dumb waiter by means of which they could draw up 
seeds and other dainties; finally a little house with open doors and 
windows, which was the only place heated during the winter. 
This central cage is surrounded by a broad public corridor, in which 
are hanging baskets or pedestals for green plants or flowers; along 
each side of the building is a series of cages communicating with 
out-door cages. Two of these lateral cages thrown together form an 
apartment for a young Kooloo-Kamba chimpanzee; one of these 
cages has a warmed retiring cage, in the form of a long box, in which 
the animal generally passes the night; the other chamber, containing 
a certain number of playthings with which he occupies most of his 
time, communicates with the corresponding exterior cage. 
There are still other installations for the monkeys (of which a new 
species of chimpanzee and a hamadryas baboon have bred) situated 
not far from this large house. I again noted here the increasing 
tendency to place the animals in the cold open air;¢ a treatment not 
“T received, at the end of last January, a letter from Mr. Jennison saying 
that his chimpanzees continued in very good health, and that they still, at that 
time, passed a part of their life in the open air. He informed me at the same 
time that he was about to add to the great monkey palace an open-air cage 
haying the dimensions of 8 by 8 by 5 meters. Besides, all the windows on the 
west side of the palace have been taken out, so as to permit the exterior air 
to have free access to the very interior of the house. . Mr. Jennison adds, “ In- 
deed we have remarked that not one of our monkeys that live in the open has 
ever suffered from paralysis of the lower limbs, which is fatal to so many of 
our other monkeys.”
