f, swollen, and painful;
these symptoms increased, and by the following morning the whole hand
and arm, as far as the elbow, had attained an exceedingly large size.
After suffering about two months, the poor fellow was removed into St.
Thomas's Hospital, where the diseased arm was amputated by Mr. Travers,
and the patient soon recovered his accustomed good health.

MOLES.

In those districts where moles abound, it may be remarked that
some of the mole-hills are considerably larger than others. When
a hill of enlarged dimensions is thus discovered, we may be almost
certain of finding the nest, or den of the mole near it, by digging
to a sufficient depth. The fur of the mole is admirably adapted from
its softness and short close texture for defending the animal from
subterraneous damp, which is always injurious, more or less to
non-amphibious animals; and in this climate, no choice of situation
could entirely guard against it. It is a singular fact that there are
no moles in Ireland. May not the dampness of the climate account for
their not thriving there?--_Edinburgh Lit. Gaz._

CHANGES IN ANIMALS.

All domestic mammiferous animals introduced into America have become
more numerous than the indigenous animals. The hog multiplies very
rapidly, and assumes much of the character of the wild boar. Cows did
not at first thrive, but, in St. Domingo, only twenty-seven years after
its first discovery, 4,000 in a herd was not uncommon, and some herds of
8,000 are mentioned. In 1587, this island exported 35,444 hides, and New
Grenada 64,350. Cows never thrive nor multiply where salt is wanting
either in the plants or in the water. They give less milk in America,
and do not give milk at all if the calves be taken from them. Among
horses the colts have all the amble, as those in Europe have the trot:
this is probably a hereditary effect. Bright chestnut is the prevailing
colour among the wild horses. The lambs which are not from _merinos_,
but the _tana basta _and _burda_ of the Spaniards, at first are covered
with wool, and when this is timely shorn, it grows again; if the proper
time is allowed to elapse, the wool falls off, and is succeeded by
short, shining, close hair, like that of the goat in the same climate.
Every animal, it would appear, like man, requires time to accustom
itself to climate.
