The best way to test
these two papers is to lay the stamps, face down, on a black
surface, and let the light strike them at about an angle of fifteen
degrees, when the _laid_ lines are brought most plainly into view.
It is necessary, however, to place the specimens so that the light
will strike them parallel to their length, as the _laid_ lines run
horizontally in the 3d, and vertically in the 6d and 12d.

Series III.--This is an entirely different paper to those mentioned
above. The _laid_ lines are most distinct, while the paper is of a
different texture and color from the regular gray shade.

Series VI.--The paper of this series is almost as thick as that
employed for series XII. There is a vast difference, however, in
its appearance, as the paper of series VI. is much harder than that
of series XII. It feels greasy when rubbed between the thumb and
finger, and the color of the paper is distinctly different from
that shown by series XII.

Series VII, VIII and IX.--We are able to divide the thin-ribbed
papers into three varieties, which the description plainly
indicates. They are very distinct, and can be distinguished by a
moment's inspection without hesitation.

Series X.--This is a very peculiar sort of paper, which is quite
fragile, and will not bear much handling. It is quite as soft as
that of series VII.

Series XI.--This paper is also of a peculiar texture; the surface
presents a sort of hairy appearance, and the quality is better than
Series X, although not as tough as series XII.

Series XII and XIII.--This paper presents, even when looking at the
face of the specimens, so entirely different an appearance to that
employed in any of the other series, that a reference to the back
is hardly necessary. It is found in two thicknesses, which have the
same appearance, and seems to have been employed for all the values
except the 12d.

Series XIV.--We are surprised that this variety has hitherto
escaped notice. It is so distinct, both in paper and color, from
any of the other 6d stamps. It has only been found in shades of a
peculiarly _brownish purple_ which is a color entirely different
from that presented by specimens on any other of the papers
employed. It is an exceedingly rare variety.

It would indeed be a task for the
