EXTRA VOLUMES OF STUDIES.

In connection with the regular annual series of Studies, a series of Extra Volumes is proposed. It is intended to print them in a style uniform with the regular Studies, but to publish each volume by itself, in numbered sequence and in a cloth binding uniform with the First, Second, Third, and Fourth Series. The volumes will vary in size from 200 to 500 pages, with corresponding prices. Subscriptions to the Annual Series of Studies will not necessitate subscriptions to the Extra Volumes, although they will be offered to regular subscribers at reduced rates.
