Fame appears to have followed rapidly on the appearance of this Specimen. The sheet was included as an inset plate in the second edition of Ephraim Chambers’ _Cyclopædia_ in 1738,[473] with the following flattering notice:—“The above were all cast in the foundery of Mr. W. Caslon, a person who, though not bred to the art of letter-founding, has, by dint of genius, arrived at an excellency in it unknown hitherto in England, and which even surpasses anything of the kind done in Holland or elsewhere.” Caslon made a further addition to his stock of matrices in 1739 by the purchase of half of Mitchell’s foundry,[474] of which the most interesting items were a Pica Greek, sets of Music and flower matrices, and six sizes of Black. The remainder, consisting of Romans and Italics, do not appear to have added much to the resources of the Chiswell Street foundry.[475] In the year 1742 Mr. Caslon’s eldest son, William—at that time twenty-two years of age—entered the business, and in the Specimen of the same year his name first appears in conjunction with his father’s. Unfortunately, no copy of this Specimen (which had evidently been seen by Nichols[476]) is known to be extant. Another Specimen, also unfortunately missing, is mentioned by the same authority, who says, “the abilities of the second Caslon appeared to great {242} advantage in the specimen of the types of the learned languages in 1748.”[477] A further Specimen was issued in the following year, in broadside form, which displayed a large variety of letters, from Canon to Pearl, many of them being the handiwork of Caslon the younger. It is possible that this last sheet may have been sent, for the most part, abroad; for while no copy of it is to be found in this country, we find one mentioned with commendation by Fournier in 1766,[478] and another preserved to this day in the Sohmian Collection at Stockholm, where, along with several other rare English and foreign specimens, it has been recently discovered by, the indefatigable Mr. William Blades. In Ames’ _Typographical Antiquities_,[479] published in 1749, appears a specimen of “Mr. Caslon’s Roman letter and the names of the sizes now in use,” the introductory note to which affords the first definite notice of the younger Caslon in connection with the foundry. “The art,” says Ames, “seems to be carried to its greatest perfection by Mr. William Caslon, and his son, who, besides the type of all manner of living languages now by him, has offered to perform the same for the dead, that can be recovered, to the satisfaction of any gentleman desirous of the same.”
