The value of the library is not easily estimated by the number of its volumes. It contains many works which are not possessed by any other library in the United States; and on this account is often visited by scientific men from a distance.
The Society meets every Tuesday evening throughout the year; and publishes periodically a journal of its proceedings, which is circulated among the learned societies of all parts of the world.
Since the year 1828 the museum of the Academy has been open gratuitously two afternoons in every week; tickets of admission on Tuesday and Friday afternoons, from one o’clock P. M. till sunset, are furnished on application to any member of the Society.
The Institution is sustained by the annual contributions of the members, and by donations from those generous persons who are friends of natural science. The names of donors to the museum and library are attached always to whatever they present, and are published in the journal of proceedings.
A full history of this most valuable but little known institution has been recently printed; copies of it may be obtained, at a trifling cost, from the doorkeeper on days when the hall is open to the public.
