As has been stated in previous reports, the condition of 
the old aviary, latterly used for the accommodation of the 
collection of reptiles and amphibians, was such that it was 
altogether unfitted for the purpose, and for some years 
these important branches of zoology have been almost un- 
represented in the Garden. The necessary repairs and al- 
terations were conducted during the summer, and the build-

condition, it consists of a central square — the old portion —

west sides, each twenty-eight feet deep by thirty-two wide, 
with semicircular ends — the full length of the building 
being ninety-two feet. The effect of the interior upon the 
eye is highly pleasing, the specimens in many of the cases 
being kept upon the natural earth, among growing shrubs 
and plants, while the experience of the past winter has 
shown the arrangement of the building to be well adapted 
to the end in view. As was anticipated, this building forms 
one of the chief attractions of the Garden. 
No other work, beyond ordinary repairs, has been done 
during the year.

time has the collection been so well able to fill its part among 
the educational institutions of Philadelphia as at present —
