It is gratifying to be able to report that there was an in- 
crease over the previous year both in the number of species 
which bred in the Garden and the number exhibited for the 
first time. 
It may be interesting to mention that a California hair seal, 
which died in December, had been in the collection for four- 
teen years and six months; this is believed to be the record 
length of life of this species in captivity. An American 
bison bull, sold in January, and a zebu cow, which died in the 
same month were born in the Garden in 1887. 
Many of the losses during the year may be attributed to 
the desire of the average visitor to feed the animals, and while 
this may be checked to some extent, it is, unfortunately, 
impossible to prevent it altogether. 
The male Siberian tiger, which came from Vladivostok, 
and the lioness, which has always shared his cage, were kept 
without artificial heat during the winter and given free access 
to an outdoor cage. The tiger caught cold at the time of the 
first hard frost and showed signs of discomfort. He quickly 
recovered, however, and he and the lioness have remained in 
perfect health throughout the winter. 
Two halfgrown hamadryas baboons from North Africa 
were also, as an experiment, kept in an outdoor cage, and 
remained in good health and condition, except that both lost 
from freezing the last joints of their tails, which, in the adult 
animal, carry the lion-like tuft.
