ONI)ON, MONDAY, SEPTEMBER 1, 1845.

The arrival of the Cambria mail steam-ship on Thurs-
day morning at Liverpool, from Boston (which passage,
including the time occupied by her usual detention at
Halifax, she effected in eleven days and less than half
of another), brings advices of considerable interest from
New York and from Mexico. From Mexico we have a
proclamation, or circular, dated July 16, 1845, by the
Mexican Ministers of War and Marine, and addressed
to the Generals..in•Chiefs of divisions, announcing the
intention of the Supreme Government to communicate
on the ensuing day to Congress its declaration of war
against the Ur ited States, for their perfidious conduct in
the affair of Texas. The " Circular" is couched in
terms of great moderation and dignity, but they do not
the less on that account bespeak a settled purpose, on
the part of the Mexican authorities, to resist with a high
band the outrageous insult which the annexation of
the Texas territory to that of the Federal Union has
put upon a sister Republic. From the stern promptitude
with which the Mexican nation resented and revenged, in
July, 1824, the attempt of ITURBIDE to superinduce an
uir r al domination on her more popularised institutions,
we. are fully prepared to expect that she would still more
deeply resent a flagrant and outrageous violation of the
intgrity of her National Republic. We are far from
regarding, therefire, her first step towards war with the
United States as a mere "bruturrifultnen."
L.rt• rs from /%1.(:w York allude to further proceedings
o OF- pa, t• .1 officers of the United States, which seem
to imply an qaally tenacious spirit of aggression, in
ti.. , • oer n t, as to other territories still more remote
3. x-t-. In addition to the march of Colonel
vey's det•ichrac•nt of 300 Dragoons of the United
i• army, fr m their cantonments at Leavenworth, in
order. t • ••• •v ,as it was said, the advance of American
etni.trantN to the 0, g as territory, whither they were to
be •so •rted as car as the southern pas,,e3 of the rocky
mountains ; it aow appears that a Captain FREEMONT
has sailed "in the same interest," on an exploring
exi,•lit‘o • n the first insra lee to Drake's River, and
t the Bay of San Francisco. This fact
woe( ; ,v,• neon suffi •iently significant of itself, even
11E1,1 it been unaccompanied by the circumstance that this
forms the third expedition of a similar character which
the a .me has conducted to the same quarters.
13,1 tiff+ intelli4,nce, in the case,i both of Mexico and
N... York, .•arries with it a moral, on which we cannot
refrain 'rom a_min t••u .hing, although we have so ofte
advert-d to it already. In the case of Mexico ,
our •lly, the favourite principle of our modern foreign
non intervention, has been carried out to a mgostPorucy,
tionable extent. A war which may involve the nobles;
States that civilisation can boast, may yet be the result
of a carelessness or timidity of tone in the representations
which our Government has made to the aggressive party,
in the incipient stages of her spoliation-schemes since
accomplished upon its victim. In the case of the Oregon,
a calamity not less grave or deplorable may yet ulti-
• mately attest the folly and imbecility of our diplomatic
credulity—in past years—with regard to the postpone-
ment of formal details, on the faith of the United States'
Government being ready at any future time to execute
the letter of compacts, the principle of which it had
already pledged itself to. But we are fain to believe
that her MAJESTY'S Ministers have really come to a
well-considered determination to throw to the winds, in
all future dealings with the Oregon question, all idea of
resorting to those expedients for tiding over, and leaving
it to time to accommodate, those great disputed points
with which the main principle of our rights in that
Tarter is inseparably bound up. The United States
