Alphabetical Table of Subjects (p. xxxix.), not in any way designed to take the place of a General Index, but merely intended to guide the reader to the several parts and sections of the Volume, has been appended to the usual Table of Contents.
The labour involved in the preparation of the present Volume has been so great that the entire time at command of the Editors has been necessarily devoted by each of them to his particular department of the Work; and they regret that they have thus been prevented from availing themselves of all the aid which the kindness of the profession has placed at their service. Much assistance, however, has been received, and for this they hope to make suitable acknowledgment in the Preface to the third Volume.
In conclusion, the Editors beg to state that they will be very grateful for any suggestions, corrections, and emendations which may reach them in time to admit of insertion in the text of Volume III., or in the Addenda to the whole Work.
