PRACTICAL WORKING OF THE PRIMATES HOUSE, 
The Primates’ House has now been in active use for a little 
more than two years; and inasmuch as the entire building was 
evolved from our own ideas, it is now proper to place on record 
our estimate of its working value. It is no exaggeration to say 
that this building has not only come up to our expectations, but, 
in many respects, has surpassed them. 
All persons familiar with zoological gardens are well aware 
of the fact that the odors of monkey houses are difficult prob- 
lems to contend with. Wherever either ventilation or cage sani- 
tation is imperfect, the odors become disagreeable—especially 
in winter weather, when doors and windows must be closed, and 
the supply of pure air is necessarily restricted. The best evi- 
dence that can be offered of the success of the ventilating sys- 
tem of our Primates’ House lies in the expressions of satisfaction 
that have been offered, voluntarily, by visitors. The absence of 
the usual ape and monkey odors from the Primates’ House— 
even in the severest winter weather—is frequently remarked by 
visitors, and from this fact we have reason to believe that the air 
supply is pure, and therefore beneficial to the living inhabitants 
of the building.
