fever will doubtless be practically eradicated before long
through the result of these scientific discoveries.

=Treatment of Mosquito Bites.=--To prevent mosquitoes, fleas, lice,
horseflies, etc., from biting, it is necessary merely to dip the clean
hands into a pail of water in which, while hot, one ounce of pure
carbolic acid was dissolved, and while they are thus wet rub the
solution over all the exposed skin and allow it to dry naturally. A
mixture of kerosene (petroleum) and water used in the same way will
also afford protection. All poisons introduced into the body by
insects are of an acid nature, and to this quality are due the pain
and irritation which it is our object to overcome. The best remedy,
naturally, is an alkali of some sort. Water of ammonia, diluted, or a
strong solution of saleratus or baking soda in water, are the two most
successful remedies to apply, either through bathing, or on cloths
saturated in one of the solutions. Clean clay, mixed with water to
make a mud poultice, is a useful application in emergencies.

=BEE, WASP, AND HORNET STINGS.=--The pain and swelling are produced by
the poison of the insect which leaves the poison bag at the base of
the barb at the instant that the person is stung. The bee stings but
once, as the sting being barbed is broken off, and is retained in the
flesh of the victim. The sting of the wasp and hornet is merely
pointed, and is not lost during the stinging process so that they can
repeat the act. Bee keepers, after being stung a number of times,
usually become immune, i. e., they are no longer poisoned by bites of
these insects.

It is well to extract the sting of bees before all of the poison has
come away. A fine pair of forceps is useful for this purpose; or, by
pressing the hollow tube of a small key directly down over the
puncture made by the sting, it may be squeezed out.

Ammonia water, as recommended for mosquitoes, is the best remedy to
relieve the pain.

=WOOD TICKS.=--Ticks inhabit the woods and bushes throughout the
temperate zone, and at certain periods during the summer season attack
passing men and animals.

The common tick is nearly circular in shape, very flat, with a dark,
brown, horny body about one-sixteenth to one-eighth inch in diameter.
Each of its eight legs possesses two claws, and the proboscis incloses
feelers which are similarly armed. The beetle plunges its barbed
proboscis into the flesh of man or animals, and holds o
