No such miracles have ever
before been wrought by physicians as those which we see in connection
with the internal secretion of the thyroid gland. The myth of bringing
the dead back to life has been associated with the names of many great
healers since the incident of Empedocles and Pantheia, but nowadays the
dead in mind and the deformed in body may be restored by the touch
of the magic wand of science. The study of the interaction of these
internal secretions, their influence upon development, upon mental
process and upon disorders of metabolism is likely to prove in the
future of a benefit scarcely less remarkable than that which we have
traced in the infectious diseases.
CHEMISTRY
IT is not making too strong a statement to say that the chemistry and
chemical physics of the nineteenth century have revolutionized
the world. It is difficult to realize that Liebig's famous Giessen
laboratory, the first to be opened to students for practical study, was
founded in the year 1825. Boyle, Cavendish, Priestley, Lavoisier, Black,
Dalton and others had laid a broad foundation, and Young, Frauenhofer,
Rumford, Davy, Joule, Faraday, Clerk-Maxwell, Helmholtz and others
built upon that and gave us the new physics and made possible our age
of electricity.
