The small hole appearing in the side of type No. 4 is a perforation, and the collection contains several types, both letters and spaces, having the same peculiarity. Whether this hole was formed at the time of or after casting; whether the letters so perforated were originally model-types only, or types in actual use; whether the hole was intended for a thread or wire to hold the letters in their places during impression; or whether, for want of a type-case, it was used for stringing the types together for safety when not in use, it is as easy to conjecture as it is impossible to determine. The perforated types which we examined certainly did not appear to be older, and in most cases appeared less old than those not perforated,—the outline of type No. 4 itself shows it to be fairer and squarer than any of its companions. Another peculiarity to be noted is the “shamfer,” or cutting away of one of the corners of the feet of types 2, 5, and 6. This appears to have been intentional, and may have served the same purpose as our nick, to guide the compositor in setting. None of the types have a nick, and types 1 and 3 have no distinguishing mark whatever. The two small indentations in the side of type 2 are air-holes produced in the casting. With regard to the faces of the types, there are traces in most of the letters of the “shoulders” of the body having been tapered off by a knife or graver after casting, so as to leave the letter quite clear on the body. In most cases the letter stands in the centre of the body, which is, as a rule, larger than the size of the character actually requires. In point of thickness, however, the old printers appear to have been very sparing; and a great many of the letters, though possessing ample room “body-way,” actually overhang the sides, and are what we should style in modern terminology “kerned” letters. The difficulty, however, which would be experienced by printers to-day with these overhanging sorts, was obviated to a large extent in the case of the old printers by the numerous ligatures, contractions, and double letters with which their founts abounded, and which gave almost all the combinations in which an overhanging letter would be likely to clash with its neighbour.
