For other varieties in this series we have the 1/2 cent on "bluish-white wove paper", listed by M. Moens in the sixth edition of his catalogue. Messrs. Corwin and King say this "corresponds to our grayish paper, the shade sometimes being quite intense." But they list the entire series on "thin, soft, grayish wove paper", as well as the 1/2 cent and 1 cent brown-red on "pelure grayish paper". It may be that imperfect wiping of the plates had left an extra grayish tint upon the paper of the specimen that Moens singled out for cataloguing, just as occurred in the case of most values of the Post Office Department stamps of the United States. Messrs. Corwin and King[100] give an extremely lengthy reference list of this issue on no less than _seventeen_ varieties of paper, with the remark that, "every variety we mention is distinct from any other", but, with Major Evans, we must remark that "we confess we are unable to follow our friend Mr. King through all the intricacies of these varieties of paper ... but the differences are, perhaps, more real than is indicted in the descriptions." On inspection the "seventeen varieties" seem to combine themselves into I: laid paper, of thick and thin qualities; II: watermarked paper; III: yellowish wove paper, very thin to very thick; and IV: grayish wove paper, from pelure to very thick. In both of the wove papers are found the differences due to the process of manufacture, the even texture of the plain wove variety and the mottled texture of the so-called "wire-wove" variety.

The paper used for this issue is responsible for variations in the size of the stamps similar in character and origin to those we have already thoroughly discussed in connection with the 7-1/2 and 10 pence stamps of 1855-7. The design of the series is not calculated to render these variations so apparent as in the former case, but the extreme variations we have found have been carefully noted and are presented in the following list. It will be seen that the variation is confined to a half millimeter in each dimension. 1/2 cent, 16-3/4 × 21-1/2 mm. 17 × 21 mm. 1 cent, 19-1/2 × 24-1/2 mm. 20 × 24 mm. 2 cents, 19-1/2 × 24-1/2 mm. 20 × 24 mm. 3 cents, 19-1/2 × 24-1/2 mm. 20 × 24 mm. 5 cents, 19 × 24-1/2 mm. ? ? 6 cents, 20 × 24-1/2 mm. 20-1/2 × 24 mm. 12-1/2 cents, 19-1/2 × 24-1/2 mm. 20 × 24 mm. 15 cents, 19-3/4 × 24-1/2 mm. 20 × 24 mm.
