The losses by death have of course been large, as must 
always be the case when living animals which, in a state of 
nature, exist only under conditions fixed within narrow 
limits of change, have those conditions suddenly and vio- 
lently altered by the restraints of domestication. It is be- 
lieved, however, that they have been less than those which 
are commonly experienced in zoological collections, and it 
is satisfactory to be able to state that with the improvement 
of buildings and enclosures, and with the added experience 
of years, the prevalence of acute diseases has been steadily 
decreasing, and with this appears an average increase in the 
lifetime of the animals placed in the Garden. 
The cost of maintaining the Garden has largely decreased.
