The eight faces of types show their relation to each other, not only by common features, but by the occasional appearance of two faces in one book. That they were never used by any printer of Germany, nor by any known printer of the Netherlands, is acknowledged even by those who dispute their age. That they were founded and used in the Netherlands, and probably in Holland, may rightfully be inferred from the language of two editions of the same book, from the Dutch fashion of the letters in all the books, and from the fact that all existing copies or fragments of works in these types have been discovered in the Netherlands. That they were the work of one printer, or of the successors of that printer, is highly probable. But this admission involves difficulties. These eight faces of types were founded on as many different bodies: four of these faces are on bodies nearly the size of English; two of them are on bodies about the size of Great-primer. The modern printer is at a loss to imagine why his unknown predecessor should have cut so many punches and made so many fonts of types with faces closely resembling each other, yet so unlike that they could not be used together. His perplexity is increased when he discovers, after careful measurement, that each face on English body and each face on Great-primer body was cast in a new or different mould. It would seem that the unknown printer of the _Speculum_ not only incurred the needless expense of cutting new punches and making new moulds for every new font of types, but that he intentionally introduced in his printing office bodies so nearly alike that they could not, in the shape of single types, be distinguished apart.
