THE ARSENAL.

This building is situated on Fifth Avenue, just within the Park enclosure. It was originally used for the purpose designated by the name it bears, but is now a free museum of natural history and art. It contains the nucleus of the Zoological Garden, which is now in course of construction near the centre of the Park, on the line of Eighth Avenue, and though the collection of animals, birds, etc., is small, it is very interesting. In the upper part of the building are the models of the sculptor Crawford, presented to the city by his widow, and many other interesting specimens of art.
