In like manner it was clear that in
our educational schemes for the benefit of the people, there must not
only be the scientific investigator of abstract truth, but also the
scientific technologist to point the way to the practical realisation of
tangible profit. Moreover, and a still more important truth, it is the
scientific education of the proprietors and heads we want--educated
capital rather than educated workmen.
_Borax._--A good deal of the Tuscan boric acid is used in France for the
manufacture of borax, which is a sodium salt of boric acid. Borax is
also manufactured from boronitrocalcite, a calcium salt of boric acid,
which is found in Chili and other parts of South America. The crude
boronitrocalcite or "tiza" is boiled with sodium carbonate solution,
and, after settling, the borax is obtained by crystallisation. Borax
itself is found in California and Nevada, U.S.A., and also in Peru,
Ceylon, China, Persia, and Thibet. The commercial product is obtained
from the native borax (known as "tincal") by dissolving in water and
allowing the solution to crystallise.
