iate destruction of the animal is advised. A burn of the third
degree, where there is a destruction of the vitality of large areas of
tissue, even on parts not subject to much motion, is extremely tedious
to treat; in fact, it is questionable whether the treatment and keep of
the animal will ever be compensated for, even though recovery does take
place; this, in any event, will require at least six or eight weeks.
Burns caused by lightning stroke and trolley wires are liable to occur
in irregular lines, and, unless death occurs at once, they generally are
not serious.

_Treatment._--Treatment should be prompt and effective. If the burns are
extensive, the constitutional symptoms should be combated with whisky
and milk and eggs, or ammonia carbonate, strychnin, caffein, or other
stimulant to prevent shock. In the local treatment, to alleviate the
pain, the application of cold water in some form and the hypodermic
injection of morphine are to be recommended. In burns of the first
degree, where there is only a superficial inflammation, lead carbonate
(white lead) ointment is very good. Carron oil (limewater and linseed
oil, equal parts) is a standard remedy, but a modification of it known
as Stahl's liniment is perhaps better. This is composed of linseed oil
and limewater each 200 parts, bicarbonate of soda 100 parts, and thymol
1 part. The scorched surface should be covered with this liniment and
then with a layer of borated gauze or absorbent cotton, to protect from
the air. The application should be frequently renewed. Carbolated
vaseline may be used in place of the above. In case the burn is more
extensive, the following solution may be used: Picric acid 2 parts,
alcohol 40 parts, water 400 parts. The lesion should be thoroughly
cleansed with this solution used on absorbent cotton. The vesicles, if
any appear, should be opened with a clean needle, allowing the skin to
remain. Strips of gauze or absorbent cotton saturated with the solution
should now be applied and renewed only occasionally. In burns of the
second and third degrees more satisfactory results may be obtained with
nonpoisonous, dry dressing powder, such as is used in ordinary open
wounds, as tannic acid 8 parts and iodoform 1 part, or a salve made of
this powder and a sufficient quantity of vaseline. When sloughing of the
tissues takes place the wounds should be cleansed with a warm 3 per cent
solution of carbolic acid, all loose fragments of tissue removed
