The President.-The next action in the order of business should be a report from the Council in regard to the general condition of the Society. A Council meeting was to have been held this morning; but the early meeting of the Society, and the fact that members do not come in promptly would prevent our having a quorum. I can say, however, all that need be said in the matter. The Society has increased in membership since the first of the year just closed, from 297 to 354, if we include those balloted for to-day. During the year the Secretary has issued Volume II. of the Transactions, and it has been sent out to members. The papers of the last meeting were to have been sent in by the printers to-day, and the Secretary expects them every moment. The report of the Treasurer lies before me, and I will ask the Secretary to read it. The Secretary then read the Treasurer's report as follows:
