THE SEVENTY'S YEAR BOOK.
The importance of Seventies having a complete set of the Seventy's Year Books cannot be over-emphasized. There is constant reference made in the present Number to previous Numbers; and the student who is not in possession of those books is by so much deprived of the opportunity to complete his inquiry on the division of the subject he may have in hand. As there are now four of the Year Books issued, they could be bound together; or in more convenient form, two numbers can be bound together at a cost of seventy-five cents, postage prepaid, and those desirous of preserving the set would do well to order them in that form.
