An army surgeon, discussing the nature of cholera and the sort of
precautions to take against the plague, says:
Our greatest defense against this disease is, as usual, provided
by Nature herself. These organisms can not live in an acid
medium; they soon perish in the stomach, when exposed to the
action of the gastric juice, because of its acidity.
Thus is nature kindly. Thus is the kindness to man of nature’s God.
