the leaves, or make them up in thick sections. Cracks in the wood block, which have made open seams or white gaps in the print, and which extend in straight lines over both pages, show conclusively that two pages were engraved on one block.
The book is without folios or paging figures to guide the reader, and also without signatures to guide the binder. The proper order of the pages was made manifest by engraving on each page a letter of the alphabet. Pages 1 to 20 are marked in alphabetical order from a to v; pages 21 to 40 have the same letters, but with a dot before and after each, .a. to .v.
The paper of the fifteen known copies of this edition of the book is of variable quality. Of itself, this variability is not sufficient indication that the paper was made by different makers, and printed at different times, but the different designs of the paper-marks lead directly to such a conclusion. Some copies have but one kind of paper-mark; others have two and three kinds; taking all copies together, there are at least fourteen distinct paper-marks. If each decided variation of the same design could be considered the mark of a different maker, the number could be doubled.
That the substance used for these engravings was wood, is clearly indicated by the occasional feathering or flatting out of border-lines, which, when crushed, show the fibres of wood in the impression. It seems that the engravings were cut on flat plates or blocks, that had been sawed or split on a line parallel with the fibres.
The ink is of a dull or rusty-brown color; on some pages light, and on others of darker tint, rarely ever of uniform tint on the same page. It has the appearance of a paste or a thick water color. This unevenness in color was produced by some imperfect method of inking the block — possibly by a hard-faced brush which shed color irregularly.
The shining appearance of the backs of the prints, in all places where the raised lines of the wood-cut have indented the paper, has been considered as sufficient evidence that the impressions were taken, not by a press, but by means, of a
