The most ancient manuscripts, both on papyrus and parchment, were kept
in rolls, called in Latin _volumina_, whence our English word "volume."
Chinese paper, made from the bark of the bamboo, the mulberry, or the
khu-ku tree, and so extremely thin that it can only be used on one side,
is supposed to have been invented fifty years before the Christian era
or earlier. Chinese rice-paper is made from the stems of the bread-fruit
tree, cut into slices and pressed. The skins of all kinds of animals
are used--among them the African skin, of a brown color, upon which the
Hebrew Pentateuch and service-books used in the Jewish synagogues were
formerly written. Silk-paper was prepared for the most part in Spain
and its colonies, but was never brought to much perfection. Asbestos, a
fibrous mineral, was made into paper, tolerably light and pliant, which,
being incombustible, was denominated "eternal paper." Herodotus tells
us that cloth was made of asbestos by the Egyptians; and Pliny mentions
napkins made of it in A.D. 74. We know by tradition that the intestines
of a serpent served for Homer's _Iliad_ and _Odyssey_; and that the
_Koran_ was written in part on shoulder-bones of mutton, kept in a
domestic chest by one of Mahomet's wives.

We now come to the great period of writing-papers made from cotton and
linen rags, as used at the present day, and which from the first were
so perfect that they have since undergone no material improvement.
Cotton-paper was an Eastern invention, probably introduced in the ninth
century, although not generally used in Europe till about the twelfth and
thirteenth centuries. Greek manuscripts are found upon it of the earlier
period, and Italian manuscripts of the later. It seems to have prevailed
at particular periods, in particular countries, according to the
facilities for procuring it, as it now does almost exclusively in
America. Linen paper, the most valuable and important of all the bases
