ees, it destroys all insects in and about the bark, and
clears the blight on apple trees. For these purposes the solution
should be applied with a brush. For washing the shelves, boards, and
woodwork of greenhouses, the solution is especially valuable, and when
used for syringing vines in the proportion of a pint of the solution
to ten gallons of water, and half a pound of borax dry soap, as soon
as the grapes have been thinned, it will keep them free from red
spider and all other insects.

2323. Fever or Infection.

In all cases of fever or infectious diseases, it should be freely used
in the room by dusting the dry powder over floors, carpets, mats, &c.
(it will not injure the finest fabrics), and by placing in dishes or
other vehicles, into which hot water should be poured. It has _no
smell_, but quickly removes _all smells_. In cases of death it is most
valuable; the corpse may be kept perfectly sweet by merely dusting
into ears, nose, mouth, under arm-pits, feet, &c., or when any
moisture exudes. It will preserve features and skin fresh as in life
for many weeks, and keep the corpse free from decomposition.

2324. Vaseline.

What it is.--This indispensable household requisite is a product of
petroleum, from which it is obtained by an elaborate system of
nitration, without the addition or aid of any chemical whatever. The
substance thus produced, to which the name of "Vaseline" has been
given, is in the form of a lemon-coloured jelly, completely devoid of
either smell or taste, and of exquisite softness and smoothness to the
touch. This jelly, which is one of the finest emollients known, and is
possessed of healing and other medicinal properties, forms the basis
of many preparations which are now widely used all the world over.

2325. Vaseline for Medicinal Use.

The pure jelly itself, without any addition, is an invaluable family
remedy for burns, chilblains, chapped hands, and skin roughened by
exposure to wind and water in cold weather; as well as for sun-burns,
wounds, sprains, and all diseases of the skin; for inflamed eyelids,
and for preventing pitting in small-pox, when used externally as an
ointment. When taken internally, in doses of half a teaspoonful, or in
smaller quantities, it forms a cure for diseases of the throat, chest,
and stomach, and gives speedy relief in cases of diphtheria, croup,
&c. For convenience in using it,
