The mailing of the first number was delayed by causes incident to the arranging and printing of new mailing lists. We have endeavored to supply accurately all the members who have been reported to us by the Treasurer as having paid their annual membership fees, and also all others who had sent us pledges of support. If any find themselves omitted, or their addresses incorrect, they will confer a favor by promptly notifying us. Let it also be remembered that all payments of membership dues should be made to the Treasurer, Dr. R. J. Dunglison, P. O. Box 2386, Philadelphia, Pa. And all subscriptions from non-members or other matters of business, should be sent to the office of publication, 65 Randolph street, Chicago.
