em from it, without the nonsense of going into
harbour to "expurgate." Now, with respect to the _Topaze_, it appears
that while lying in harbour in Ceylon, the disease broke out on
board her; that after she got into "_clene air_" at sea, the disease
disappeared, seventeen cases only having occurred from the time she left
the island, and she arrived at the Mauritius, as Dr. Hawkins admits,
without any appearance whatever of the cholera on board. On the day
after her arrival, she sent several cases ("chronic dysentry, hepatitis,
and general debility") to hospital, but not one of cholera; neither did
any case occur on board during her stay there, at anchor a mile and a
half from shore, and constantly communicating with shore,[5] while a
considerable number of deaths took place from cholera _in the merchant
vessels anchored near shore_.

[Footnote 5: Somebody is said to have seen a man on board with vomiting
and spasms, on the day before she moved to this anchorage, but the
surgeon of the ship has not stated this.]

As to the introduction of cholera from the Mauritius into Bourbon, where
it appeared but very partially, Dr. Macmichael very properly does not
say one word. There was abundance of "precaution" work, it is said,
and those who choose, are at liberty to give credit to the story of
its having been smuggled on shore by some negro slaves landed from a
Mauritius vessel. As to the _precautions_ to which the writer in _The
Westminster Review_ attributes the non-extension of the disease in this
island, hundreds of instances are recorded, in addition to those which
we have already quoted, of the disease stopping short, without cordons
or precautions of any kind--one remarkable instance is mentioned by Dr.
Annesley, where, _without seclusion_, the disease did not reach the
ground occupied by two cavalry regiments, although it made ravages in
all the other regiments in the same camp.

We have, perhaps, a right to demand from those gentlemen who display
such peculiar tact in the discovery of ships by which the cholera has,
at divers times, been imported into continents and islands, the names
of those ships which brought to this country, in the course of the
present year, the "_contagion_" which has produced, at so many
different points, cases of severe cholera, causing death in some
instances, and in which the identity with the "Indian cholera," the
"Russian cholera," &c., has been so _perfect_, that all the "perverse
