History of the Postage Stamps of the United States of America - John K. Tiffany

With the frame line on the left split into two parts from the level of the chin up, the inner touches the rosette, the triangle and almost touches the block. The right frame line is split into two parts in the lower half. Both the right triangles have the finer line, and the upper the extra vertical line, q¹ i² n² U^{2 4} S⁴.

With the extra outside line from level of lips to the upper rosette. All four triangles are connected with the blocks, the upper right and lower left have the extra vertical line, r¹ U^{1 2 3 4} S^{3 4}.

With extra outside line from level of the lips to the level of the center of the rosette. The frame line is too near the top on the left, the upper right triangle is connected with the block, and has the extra vertical line, the lower right triangle is also connected with the block, s¹ h¹ S^{2 4} U².

With the extra left line from the level of the nose to the top of the rosette, the upper right triangle connected with the upper block, and with extra vertical line, t¹ S² U².

With the extra line on the left from the level of the breast to the top of the rosette, the frame line is too near the upper left corner, and an extra vertical line in all the triangles, u¹ i¹ U^{1 2 3 4}.

With the extra line on the left opposite the bottom rosette only. The two upper triangles are connected with the blocks, and an extra line in the upper right one, v¹ S^{1 2} U².

With the left frame line heavy, and too near to the bottom block, a split runs off to left half way down. Both sides appear to have a heavy line from rosette to rosette, but the left one is irregular, all the triangles are connected with the adjoining blocks, and all except the lower right one have the extra vertical line, h³ n¹ S^{1 2 3 4} U^{1 2 3} K^{1 2}.

In the above descriptions, no mention has been made of those parts that are in their proper ordinary position.

These varieties are the leading ones, and are probably more than enough to show the combinations. Less conspicuous ones are numberless. Owing to the scarcity of adhering specimens, and the uncertainty as to how many plates were actually employed, no attempt has been made to reconstruct any plate. It is perhaps necessary to repeat that the collection of any, except perhaps the more marked varieties, is not advocated.
