and non-irritating diuretics. The skin may be stimulated by Dover's
powder (10 grains) or liquor ammoniae acetatis in three-dram doses every
four hours.

Various drugs administered internally, such as quinine, salol,
salicylate of iron, and others, have a reputation, more or less
deserved, as internal antiseptics.

Weakness of the heart, as indicated by the condition of the pulse, is
treated by the use of such drugs as digitalis, strophanthus, or
strychnin, according to circumstances.

Gastro-intestinal disturbances are met by ordinary medical means.
Vomiting, for example, can sometimes be checked by effervescing drinks,
such as citrate of caffein, or by dilute hydrocyanic acid and bismuth.
In severe cases, and especially when the vomited matter resembles
coffee-grounds from admixture with altered blood--the so-called
post-operative haematemesis--the best means of arresting the vomiting is
by washing out the stomach. Thirst is relieved by rectal injections of
saline solution. The introduction of saline solution into the veins or
by the rectum is also useful in diluting and hastening the elimination
of circulating toxins.

In surgical inflammations, as a rule, nothing is gained by lowering the
temperature, unless at the same time the cause is removed. When severe
or prolonged pyrexia becomes a source of danger, the use of hot or cold
sponging, or even the cold bath, is preferable to the administration of
drugs.

_Relief of Symptoms._--For the relief of _pain_, rest is essential. The
inflamed part should be placed in a splint or other appliance which will
prevent movement, and steps must be taken to reduce its functional
activity as far as possible. Locally, warm and moist dressings, such as
a poultice or fomentation, may be used. To make a fomentation, a piece
of flannel or lint is wrung out of very hot water or antiseptic lotion
and applied under a sheet of mackintosh. Fomentations should be renewed
as often as they cool. An ordinary india-rubber bag filled with hot
water and fixed over the fomentation, by retaining the heat, obviates
the necessity of frequently changing the application. The addition of a
few drops of laudanum sprinkled on the flannel has a soothing effect.
Lead and opium lotion is a useful, soothing application employed as a
fomentation. We prefer the application of lint soaked in a 10 per cent.
aqueous or glycerine solution of ichthyol, or smeared with ichthyol
ointment (1 in 3). Belladon
