, Ealing, and the several other villages along
the Thames, as far as Chertsey; and even Richmond, where, as at
Lewisham, there was one house where ten individuals at one time were
suffering under this disease. Whatever was the pestilence last year, it
promises to be much greater in the present one. This is easily judged
from the manner in which the season has set in, but still more decidedly
from the extraordinary prevalence of ague in the spring; since that
which was intermittent fever then, will be remittent in the autumn, or
rather, there will scarcely be a definite season of vernal intermittent,
but the remittent will commence immediately, increasing in extent and
severity as the summer advances, and promising to become, in the autumn,
the greatest season of disease that England has known for this century.
Dr. Macculloch attributes this alarming increase to _malaria_, on
the production and propagation of which he has recently published an
essay, the leading argument of which is, "that as the quantity of the
poison which any person can inspire is necessarily small, and as this
small quantity can be produced by a small marshy spot as well as a large
one, it is the same, as to the production of the disease, whether the
marsh is a foot square or a mile, provided the exposure be complete;
while also any piece of ground where vegetables decompose under the
action of water is virtually a marsh, or must produce _malaria_."

_Acclimatizing Plants_.

A Mr. Street, of Biel, in East Lothian, has recently made some
successful attempts at acclimatizing, or giving to exotic plants greater
powers of withstanding cold than they had when first introduced. By
planting in situations well drained from superfluous moisture, under
circumstances where rapid growth was rendered impracticable, and in a
garden admirably adapted to the object from its position, he has
succeeded in naturalizing, in latitude 56 deg. N. plants which have not yet
been known to endure the winters even of the parallel of
London.--_Quarterly Journal of Science_.

In a table kept at Sydney by Major Goulburn, from May 1821 to April
1822, the thermometer never rose above 751/2 deg. and never lower than 54 deg. of
Fahrenheit.

_Bronzing Tin_.

To obtain complete success in bronzing medals of tin, the two following
solutions must be employed:--

The first, which is merely a wash, is composed of 1 part of iron, 1 part
of sulphate of copper, and 20 parts, by weig
