in a warm place, then strain. Melt one ounce and a
half of white wax and half an ounce of spermaceti with the oil; stir
it till it begins to thicken, and add twelve drops of otto of roses.

ii. White wax, one ounce; almond oil, two ounces; alkanet, one

2448. Ventilating Bedrooms.

A sheet of finely perforated zinc, substituted for a pane of glass in
one of the upper squares of a chamber window, is the cheapest and best
form of ventilator; there should not be a bedroom without it.

2449. A Simple Method of Ventilation.

Get a piece of deal two inches wide and one inch thick, and as long as
the width of the sashes of the window in which it is to be used. Care
should be taken to ascertain the width of the sashes exactly, which
may be done by measuring along the top of the lower sash, from one
side of the sash frame to the other. Raise the lower sash--drop in
the piece of wood, so that it rests on the bottom part of the window
frame, the ends being within the stops on either side, and then close
the sash upon it. If properly planed up, no draught can enter between
the wood and the bottom of the sash; but the air can enter the room in
an upward direction, through the opening between the top of the lower
sash and the bottom of the upper sash, any direct draught into the
interior of the room being prevented by the position of the lower sash.

2450. Bedclothes.

The perfection of dress, for day or night, where warmth is the
purpose, is that which confines around the body sufficient of its own
warmth, while it allows escape to the exhalations of the skin. Where
the body is allowed to bathe protractedly in its own vapours we must
expect an unhealthy effect upon the skin. Where there is too little
allowance for ventilation, insensible perspiration is checked, and
something analogous to fever supervenes; foul tongue, ill taste, and
lack of morning appetite betray the evil.

2451. Vapour Baths.

Vapour baths may be made by putting boiling water in a pan, and
placing a cane-bottom chair in the pan, the patient sitting upon it,
enveloped from head to foot in a blanket covering the bath. Sulphur,
spirit, medicinal, herbal, and other baths may be obtained in
