s an attack of that nature, and, generally,
cholera: fright, and intoxication, produce the same effect.

"Numerous instances could be produced of persons in perfect health, some
of whom had not left their rooms since the breaking out of the disease,
having been attacked by cholera, almost instantaneously after having
imprudently indulged in sour milk, cucumbers, &c. It is a curious
circumstance, bearing on this question, that several individuals coming
from Riga have died at Wenden, and other parts of Livonia, without a
single inhabitant catching the disease; on the other hand, it spreads in
Courland, and on the Prussian frontier, notwithstanding every effort to
check its progress. The intemperance of the Russians during the holidays
has swelled the number of fresh cases, the progressive diminution of
which had previously led us to look forward to a speedy termination of
the calamity." This is a pretty fair specimen of the _undeniable_ manner
in which cholera is proved to be contagious in Europe, and we shall, for
the present, leave Dr. Hawkins in possession of the full enjoyment of
such proofs.

Some attempt was made at Sunderland, to establish that, in the case
which I mentioned in my last as having proved fatal there, the disease
had been imported from foreign parts, but due inquiry having been made
by the collector of the customs, this proved to be unfounded; the man's
name was Robert Henry, a pilot:--he died _on the 14th of August_.[11]

[Footnote 11: In a former letter I alluded to cases of cholera which
appeared this year at Port Glasgow; I find that the highly interesting
details of those cases have been just published:--_they should be read
by everybody who takes the smallest interest in the important questions
connected with the cholera_. The London publishers are Whittaker and
Co.]

Abroad we find that, unhappily, the cholera has made its appearance at
Hamburgh; official information to this effect arrived from our Consul
at that place, on Tuesday the 11th inst. (October). The absurdity of
cordons and quarantines is becoming daily more evident. By accounts
from Vienna, dated the 26th September, the Imperial Aulic Council had
directed certain lines of cordon to be broken up, seeing, as is stated,
that they were inefficacious; and by accounts of the same date, the
Emperor had promised his people not to establish cordons between certain
states.
