A manufacture has in consequence
been established near Bristol, in which, by exposing the carcases of
horses and other animals for a length of time under water, the muscular
parts are converted into this spermaceti-like substance. The bones
afterwards undergo a different process to produce hartshorn, or, more
properly, ammonia, and phosphorus; and the skin is prepared for leather.

Thus art contrives to enlarge the sphere of useful purposes, for which
the elements were intended by nature; and the productions of the several
kingdoms are frequently arrested in their course, and variously
modified, by human skill, which compels them to contribute, under new
forms, to the necessities or luxuries of man.

But all that we enjoy, whether produced by the spontaneous operations of
nature, or the ingenious efforts of art, proceed alike from the goodness
of Providence. --To GOD alone man owes the admirable faculties which
enable him to improve and modify the productions of nature, no less than
those productions themselves. In contemplating the works of the
creation, or studying the inventions of art, let us, therefore, never
forget the Divine Source from which they proceed; and thus every
acquisition of knowledge will prove a lesson of piety and virtue.
