192 THE PRESENT EPIDEMIC AMONG CATTLE, &c. 
produced. Some little caution, however, is here requisite ; for 
twelve cows in Westmoreland were, a little while ago, drenched 
with a solution of nitre, instead of Epsom or Glauber’s salts, and 
every one of them perished. 
On the third day from the attack it will be necessary to dress 
the feet with the following mixture ; but previous to its applica- 
tion all the diseased parts and separated portions must be care- 
fully removed : — Take tar Ifciss, sulph. cupri §iii, finely powdered 
and sifted. Melt the tar, and gradually add the copper, con- 
tinuing to stir the mixture until it is cold. This ointment 
should be spread upon some pledgets of fine tow, and applied to 
the feet: one dressing will, in ordinary cases, be effectual. In 
some instances I have known sinuses form in the laminated struc- 
ture and under the ligaments. Setons judiciously placed will 
then form the best treatment. I have invariably applied the 
same mixture to the mouth by wrapping a piece of tow round 
the end of a stick, and spreading the ointment upon it, and in- 
troducing it into the mouth, when, by the motion of the tongue, 
the dressing will be diffused all over the mouth. It is of the 
greatest importance to allow the animals plenty of clean litter; 
and every other attention regarding cleanliness is indispensable. 
In cases where the breath of the animal is very offensive, I 
have used a solution of carbonate of ammonia in cold water 
twice a-day. In protracted cases, and under emaciation and de- 
bility, it is necessary to supply the patient with good gruel or ale, 
with two drachms each of ginger and gentian twice a-day. Setons 
placed on one side of the dewlap are beneficial in milch cows: I 
think this prevents the udder from becoming much involved. 
When the udder has suffered much from the disease, some parts of 
the gland becomes scirrhous. The best application is strong mer- 
curial ointment Jii, iodine 30 , camphorated oil Jiii : rub down the 
iodine with the camphor, and then add the oil. Apply it every 
day, well rubbing it in. I have also met with several cases where 
large abscesses formed on the hip, generally deep-seated, and 
containing a quantity of thin purulent matter : it is necessary to 
open them freely, and apply a saturated solution of nitrate of 
potass, and afterwards common digestive ointment. Under those 
circumstances a singular insidious lurking derangement of the 
mucous membranes of the intestines is often found. Tonics of 
the vegetable kind suspended in linseed tea are here the best 
medicine.
