We have repeated the experiment in our own foundry with Long Primer type, and with a similar result. These experiments are sufficient to show the ungroundedness of Mr. De Vinne’s argument. He further states that in some of the specimens given by him, the letters have been so worn that they have run into one another; but the fact is, such letters were logotypes, and cut on the same block. Any accurate type-founder can verify this fact almost at a glance. In a lecture by Mr. Josiah Marples, an accurate English printer, before the Liverpool Literary and Philosophical Society on _Type-founders and Type-founding_, the speaker alluded to Caxton and his types, and to Mr. Vincent Figgins’s reproduction of the “Game of Chesse,” whose nephew had enabled him to exhibit a copy of the same to the meeting. “Mr. Vincent Figgins, whose skill as a practical type-founder,” it was remarked, “entitled his opinion to great weight, believed that the book was not printed from types such as were cast by Schœffer, but from types which were cast with solid faces, upon which were cut with the graver each letter separately. To this Mr. Figgins attributed the fact that in the original book no pure style of letters was used, but a mixture between the old black and that called Secretary; that no two letters were exactly alike, and that frequent use was made of logotypes.” Mr. De Vinne finds some difficulty in demolishing the Koster “legend” (as he and Van der Linde call it) in the fact that the existence of numerous volumes and fragments of ancient printing have to be somehow accounted for; and he thereupon adopts the hypothesis of an unknown printer, to whom he attributes these early productions. The admittedly ancient water-marks in the paper he rules out, simply because such water-marks were used long afterward. He gives fac-simile specimens of the types used in these books; but, in violation of all the laws of probability, he gives the inferior specimens last. The necessities of his theory compelled him to this course, the natural order being the reverse of the one adopted by him. The inferior specimens show clearly the first attempts of an inventor, an inventor too who had before been a block printer. The succeeding books show as clearly the successive stages of improvement, the last stage of which was equal or even superior to any thing executed by Gutenberg before the appearance of the great Bible. This “unknown printer” was doubtless Koster.
