Building goes on briskly at the therapeutic Tower of Babel; what one recommends another condemns; what one gives in large doses another scarce dares to prescribe in small doses; and what one vaunts as a novelty another thinks not worth rescuing from merited oblivion. All is confusion, contradiction, inconceivable chaos. Every country, every place, almost every doctor, have their own pet remedies, without which they imagine their patients can not be cured; and all this changes every year, aye every mouth.

In 1810, the Triumph man-of-war and Phipps schooner received on board several tons of quicksilver, saved from the wreck of a vessel near Cadiz. In consequence of the rolling of the bags the mercury escaped, and the whole of the crews became more or less affected. In the space of three weeks, two hundred men were salivated, two died, and all the animals—cats, dogs, sheep, fowls, a canary bird, nay, even the rats, mice and cockroaches were destroyed.
[The leather bags of mercury had been salvaged and stored without the original wooden cases. Some were stowed in sleeping quarters, and the in same hold as spirit rations.]

Penicillin .. has stimulated the search for other antibiotics and may lead to further productive study of the metabolism of microorganisms and the enzymes by which they act. From such knowledge should come not only new weapons for fighting germs but better, more rational use of those we already have.

The question, What is cholera? is left unsolved. Concerning this, the fundamental point, all is darkness and confusion, vague theory, and a vain speculation. Is it a fungus, an insect, a miasm, an electrical disturbance, a deficiency of ozone, a morbid offscouring from the intestinal canal? We know nothing; we are at sea, in a whirlpool of conjecture.
