hundred weight.
The various weights are :—

This libra consists of sixteen unciae, and the half part of the libra is
the selibra, which our people call a mark, and consists of eight unciae, or, as
they divide it, of sixteen semunciae :—

The above is how the "greater" weights are divided. The "lesser"
weights are made of silver or brass or copper. Of these, the first and largest
generally weighs one drachma, for it is necessary for us to weigh, not only
ore, but also metals to be assayed, and smaller quantities of lead. The first
of these weights is called a centumpondium and the number of librae in it
corresponds to the larger scale, being likewise one hundred42.

The fourteenth is the last, for the proportionate weights which correspond
with a drachma and half a drachma are not used. On all these weights of
the lesser scale, are written the numbers of librae and of semunciae. Some
