121. The temperature of the room, however, should be a few degrees
higher than in scarlatina, as none of these other eruptive diseases
shows the same degree of fever and heat. This is particularly advisable
in the treatment of measles, when exposure is very apt to cause the rash
to disappear, an occurrence which is dangerous in any eruptive disease.

122. CONCLUSIVE REMARKS.--OBSTACLES.

Before concluding my article, I shall attempt to remove a few objections
and obstacles, which are usually raised against the practice of the
hydriatic system in families.

123. WANT OF WATER.

One of the obstacles is the _want of a sufficient quantity of water_ in
some houses, and the difficulty of procuring it.

This obstacle is easily removed.

If you cannot procure water enough for a half-bath--for there cannot be
a difficulty in procuring a pailful for wetting the sheet--give your
patient a _dripping sheet_ instead, which, in most cases, will do as
well; or, should there be a want of a wash-tub to give it in, a _rubbing
sheet_ may supply the bath.

124. DRIPPING SHEET, SUBSTITUTE FOR THE HALF-BATH.

To apply the _dripping sheet_, a tin bathing hat or a large wash-tub is
placed near the patient's bed, and a pail of water on the brim of the
hat, or close by the tub. Dip a linen sheet into it, and leave it there
till you wish to take the patient out of his pack, but dispose it so
that you can easily find the two corresponding corners. As soon as the
patient steps into the hat or tub, seize the sheet by these corners and
throw it over his head and body from behind, and rub him all over, head
and all, whilst somebody else is supporting him, or whilst he is
supporting himself by taking hold of one of the bed-posts. When the
sheet becomes warm, empty part of your pail over the patient's head, by
which means the water in the sheet is renewed, and rub again. Then
repeat the same operation, and when all your water is gone, before the
body of the patient is sufficiently cool, take water from the hat or tub
and use it for the same purpose, till he is quite cooled down. Then dry
him with another sheet, or a towel, and put him to bed again, if
necessary.

125. RUBBING SHEET, SUBSTITUTE FOR THE HALF-BATH.

It cannot be difficult to procure a wash-tub. Should you be so situated,
however, as not to be able to procure even this, you will be compelled
to make shift with a _rubbing sheet_. For that purpose, a sheet and a
pail of wa
