211. Gold leaf consists of a portion of the metal beaten out
to so great a degree of thinness, as to allow a greenish-blue
light to be transmitted through its pores. About 400 square
inches of this are sold, in the form of a small book containing
25 leaves of gold, for 1s. 6d. In this case, the raw material, or
gold, is worth rather less than two-thirds of the manufactured
article. In the case of silver leaf, the labour considerably
exceeds the value of the material. A book of fifty leaves, which
would cover above 1000 square inches, is sold for 1s. 3d.
212. We may trace the relative influence of the two causes
above referred to, in the prices of fine gold chains made at
Venice. The sizes of these chains are known by numbers, the
smallest having been (in 1828) No. 1, and the numbers 2, 3, 4,
etc., progressively increasing in size. The following table shews
the numbers and the prices of those made at that time.(1*) The
first column gives the number by which the chain is known; the
second expresses the weight in grains of one inch in length of
each chain; the third column the number of links in the same
length; and the last expresses the price, in francs worth
tenpence each, of a Venetian braccio, or about two English feet
of each chain.
