One Plate, the arrangement is usually thus:—

The plates are not photographs in the common acceptation of the word, but are printed in Permanent Ink, from gelatinised copper-plates, by the New York Photo-Gravure Company, on thick linen plate-paper.

The size of the paper is 45 × 60 centimetres—19 × 24 inches, and the printed surface varies from 15 × 45 to 20 × 30 centimetres—6 × 18 to 9 × 12 inches.

The number of figures on each plate varies from 12 to 36.

To publish so great a number of plates as one undivided work was considered unnecessary, for each subject tells its own story; and inexpedient, for it would defeat the object which the University had in view, and limit its acquisition to large Libraries, wealthy individuals, or Institutions where it would be beyond the reach of many who might desire to study it.

It has, therefore, been decided to issue a series of One Hundred Plates, which number, for the purposes of publication, will be considered as a "COPY" of the work. These one hundred plates will probably meet the requirements of the greater number of the subscribers.

In accordance with this view is issued the following
