On severing the stamps by tearing, a rough indented edge is left on each side; a ragged edge caused by the holes being too far apart is left above and below. A similar difference has been remarked by us in the former issues, specimens of each of which, completely perforated by either method, may be found, as also occasionally a copy showing both systems on the same stamp.” We have already in previous notes given extracts from the above to show that the difference between the A and B perforations was thoroughly understood by the writer, and also that the B perforation and the compound B×A both existed in the One Penny and the Six Pence previous to December 1866. We learn from the same source that the two colours of the One Shilling—what we have called “dark slate-grey” and “greyish-purple”—appeared in the same consignment; and, moreover, that part of this consignment of the One Shilling was perforated A, and part of it B×A, both of which statements are confirmed by Messrs. Perkins, Bacon & Co.’s list. We have found the greyish-purple very rare as compared with the other colour. The One Shilling perforated B×A is certainly much more common than the one with the A perforation, and the greater part of the consignment probably consisted of the compound. No other printings of either of the two values were ever again made in these colours on the unwatermarked paper. The Four Pence is a clear deep blue, and there are practically no shades; but as it has a strong tendency to oxidation, it is to be found in all sorts of deteriorated colours up to nearly black. Out of the 15,000 printed, a great number must have found their way into dealers’ stocks, as it is quite as common unused as used. It continued in use for some years after it had been superseded by a Four Pence of a different colour. The _Philatelist_ of February, 1873, that is three years after the issue of the Four Pence, yellow, says, “The colour of the Four Penny would seem to have reverted to its original hue, our specimens just received by the last mail being a full blue, but unwatermarked as far as we can distinguish.” Were it not for the information we have been fortunate enough to obtain from Messrs. Perkins, Bacon & Co., this might lead us to believe that another printing of the Four Pence, blue, had been made about the end of 1872; but we know that this was not the case, as only one printing of it was ever made, and the stamps alluded to must have been some of the old stock that were being used up. The One Shilling is given in the London Philatelic Society’s Catalogue as perforated 11½ on all four sides. We have not met with this variety, and do not believe in its existence. If the specimen from which the description was taken is one in the “Tapling Collection,” as seems probable, the particular stamp proves, after examination, to be merely an oxidised copy of the One Shilling, indigo, of the following issue. Issue 5. _April 1869._ 1s., indigo.
