He keeps his post continually, and will
undertake to maintain it against all the plagues of Egypt. He sets up
his trade upon a pillar, or the corner of a street--These are his
warehouses, where all he has is to be seen, and a great deal more; for
he that looks further finds nothing at all."
ABSURDITIES OF PARACELSUS, AND VAN HELMONT.
Although some of the first chemists were men of sense and learning, yet
after that chemistry began to be fashionable and much in vogue, there
were some of its professors, who although men of an uncommon turn of
genius, were as great enthusiasts, both in the chemical and medical
arts, as any other men ever were in religion. They not only pretended to
transmute some of the baser metals into gold, contrary to the nature of
things--and if they could have succeeded in that impossible work, it
would have rendered gold as plentiful, cheap, and less valuable than
iron, because it is less fit for instruments and mechanical uses--but
they also pretended infallibly to cure all diseases, by some of their
new invented chemical machines;--a thing equally as impossible as the
other, and shewed their ignorance of the causes and nature of diseases.
