run out. If matter still remains, it may be removed with a sponge. When 
canals exist where the surgeon deems it unsafe to make an opening, and a 
thin, bloody discharge comes off, indicating diseased bones and tendons, a 
weak solution of corrosive sublimate or of chloride or sulphate of zinc should 
be injected daily. When the matter becomes thick and white, calendula- 
lotion may be injected instead of the corrosive sublimate or zinc. When 
there is a low state of the system, tonics should be given, as iron and cin- 
chona. When such a state is accompanied by a thin, foul, bad-smelling and 
corroding discharge, give arsenicum. Aconite is needed for primary in- 
flammation, ten drops of dilute tincture being put in a pint of water and 
given two or three times daily until the inflammation subsides. 
WOUNDS. 
The whole subject of wounds may be treated under this general head. 
We divide the matter into four groups, namely, contused wounds, incised 
wounds, punctured wounds, and lacerated wounds. 
CONTUSED WOUNDS. 
By this term we mean those in which the skin is bruised, but not cut 
through or broken. They are caused by some mechanical violence, such as 
a halter accidentally caught around the leg, a fall, a kick, or a blow. The 
symptoms are redness, heat, swelling and pain of the affected part. 
TREATMENT.—In mild cases wet two or three folds of linen in a lotion 
made of one ounce of calendula, two ounces of glycerine and a half-pint of 
water, and place them on the parts with a wet bandage, repeating this every 
two hours. If the skin and under-lying parts are much affected, foment the 
part with warm water constantly during the day, and apply a bran-poultice 
at night. When the sore grows soft, let the matter out with a lance, or 
sharp knife, the fomentation only being then continued, If lymph forms 
instead of pus, and the swelling stil! remains, rub the part with the calen- 
dula-lotion twice a day. Should this fail, rub in daily a small quantity 
of a preparation composed of four ounces of soap-liniment and one-half 
ounce of camphor. Apply carbolic-acid lotion if flies lay eggs in the 
‘wound. 
One of the best applications for open wounds, mentioned here but 
applicable as well to clean cuts and lacerated wounds, is a decoction of but-
