to the sickness in the above army, I
showed from the text of the Bengal report, how a change of position
produced a return of health in the troops; but Mr. Kennedy states that
the disease had greatly declined a few days before the removal, so that
it had lost "its infecting power." Nevertheless it appears by this
gentleman's account, a little farther on, that "in their progressive
movement the grounds which they occupied during the night as temporary
encampments were generally found in the morning, strewed with the dead
like a field of battle"! This gentleman tells us that he has laid down a
law of "increase and decline appertaining to cholera," by which, and the
assistance of _currents of contagion_, it would appear all these things
are reconciled wonderfully. Several of the points upon which he grounds
his belief of contagion have been already touched upon in these letters,
and the rest, considering the state of the cholera question in Europe
just now, may be allowed to pass at whatever value the public may, after
due examination, think it is entitled to. Let it be borne in mind that
all contagionists who speak of the cholera in the army of the Marquis of
Hastings, forget to tell us that though many thousand native followers
had fled from that army during the epidemic, the disease did not appear
in the towns situated in the surrounding country, _till the following
year_, as may be seen at a glance by reference to Mr. Kennedy's and
other maps.

We have another contagionist in the field--a writer in the _Foreign
Quarterly Review_, the value of whose observations may appear from his
statement, that "in 1828 the disease broke out in Orenburg, and was
supposed [_supposed_!] to have been introduced by the caravans which
arrive there from Upper Asia, or [_or_, nothing like a second string] by
the Kingiss-Cossacks, who are adjoining this town, and were said [_were
said_!] to have been about this time affected with the disease." This
single extract furnishes an excellent specimen of the sort of _proofs_
which the contagionists, to a man, seem to be satisfied with as to the
cholera being "carried" from place to place. This gentleman must surely
be under some very erroneous impression, when he states that, "According
to the reports of the Medical Board of Ceylon, the disease made its
appearance in 1819 at Jaffnah in Ceylon, imported from Palamcottah, with
which Jaffnah holds constant intercourse, and thence it was propagated
