Nor was the destruction delayed by
placing choleraic excreta in or upon earth, dry or moist, or mixed with
stagnant water. In gelatine cultures the comma bacilli can be cultivated
for six weeks, and also in blood serum, milk, and potato, where anthrax
bacilli rapidly form spores. But a resting state of the comma bacilli has
never been met with--a very exceptional thing in the case of bacilli, and
another reason why the organism must be regarded rather as a spirillum
than a bacillus, for the spirilla require only a fluid medium, and do not,
like the anthrax bacilli, thrive in a dry state. It is quite unlikely that
a resting state of the comma bacillus will ever be discovered; and,
moreover, its absence harmonizes with our knowledge of cholera
etiology.--_The Lancet_.

Before entering upon my subject, I must crave the indulgence of those of
my colleagues whose language I have borrowed for any italicisms that I may
use, as well as for the foreign accent which must strike their ears more
or less disagreeably.
