We have inserted the imperforate varieties in the list, as, although we have not seen a satisfactory used copy of either value, both stamps have always been described in catalogues from the earliest to the present time. They are, for instance, so given in the catalogue of Mons. Alfred Potiquet, published in Paris in December, 1861, and also in the first edition of Mons. J. B. Moens’ _Manuel du collectionneur de Timbres-poste_, which appeared early in 1862. We think, therefore, that there can be little doubt that both stamps were issued in the imperforate state. The only postmarked specimen that has come under our notice is one of the One Penny, which is in the “Tapling Collection.” This stamp has fair margins on three sides, but is cut close on the right side, so that it cannot be considered of quite unimpeachable authenticity. Messrs. Perkins, Bacon & Co.’s books state that each lot of stamps sent out to the Island was perforated and gummed, and this applies to the first as well as to all the other consignments, so that the specimens chronicled by early writers must have come from sheets which were sent out imperforate in error. Looking at the date these varieties were first catalogued, they probably came from sheets out of the lot despatched on March 27th, 1861. Some of the later consignments seem also to have contained imperforate sheets, as we have seen an entire one of the Six Pence, which came out of the lot forwarded on June 15th, 1868. Of late years quite a number of the imperforate stamps have turned up, but we do not believe that any of these ever saw the Colony, and in our opinion they stand upon very different ground to the early chronicled varieties. Altogether there is such an atmosphere of uncertainty surrounding these imperforate varieties that, had it not been for the references to them in the above-mentioned catalogues, we should have been inclined to have excluded them from the lists, and classed them either as proofs or trials for colour. The variety of the Six Pence, imperforate vertically, is noted from a horizontal pair recently in the collection of Mr. F. de Coppet of New York, and which was sold at the sale of his stamps on December 12th, 1894. The pair was perforated all round, but imperforate between the two stamps. [5] See chronological list of Messrs. Perkins, Bacon & Co.’s printings, and consignments in Appendix D. Issue 2. _1862._ 6d., yellow-green, very slight shades, all deep. This very interesting issue consists of one value only—a yellow-green Six Pence—which not only differs in colour from any other stamp of the same denomination on unwatermarked paper, but has a perforation quite peculiar to itself among the stamps of St. Vincent.
