which tlie animal drinks, at the rate of one ounce per day, divided 
into doses in proportion to the number of times the patient in 
watered. So svon as the animal evinces signs of improvement, 
the above treatment is to be discontinued ; then give six drachms 
per day of fluid extract of prince’s pine. The joints which seem 
to be affected are to be bathed occasionally with campheorated 
vinegar, in the proportion of one ounce of camphor to eight ounces 
(fluid) of vinegar 
CHronic RHEUMATI8h 
Chronic rheumatism is usually the sequel of the acute kind. it 
is generally obstinate and lingering, and prone to recur. Unlike 
the acute kind, pain is alleviated by counter-irritation and exer- 
cise ; and when the }~tient gets warmed up, as the saying is, he 
either forgets his pains «r becomes relieved. Bathing with warm 
vinegar has a gvod effect in the treatment of this disease, but I 
have found the following liniment useful in almost all the cases 
that have come under my care: 
No. 54. Oil of cedar........ ceeseccccecsceee 2 OZ 
Sulphuric ether......ceccecccceseeeee 1 0%. 
Proof spirit... ...0.eceeececcoeceeess L pint. 
First, mix together the oil of cedar and sulphuric ether; then 
add the proof spirit, and, after shaking it awhile, it is fit for use. 
Give the animal one fluid drachm of the fluid extract of colchi- 
cum-root, night and morning, for tlLree days; after which give, 
daily, twenty-five grains of the iodide of pctass, dissolved in half 
a gill of water. Should the animal show any signs of debility or 
loss of flesh, tonics, stimulants, and nutritious diet are indicated, 
and a half of barley-water. This was followed by one grain of opium. In fif 
teen hours the pulse was found reduced, and the pain absolutely gone; and ino 
few days the tongue was clean, and the swelling entirely abated. The remedy 
eaused neither emesis nor catharsis, but passed off by the kidneys. In another 
case of acute synovial attack, following chronic rheumatism, the same dose was 
prescribed without any good effect, causing active catharsis. Again, half an 
ounce of nitrate of potassa, largely diluted, was given every two to four hours, 
antil the patient took three ounces in eighteen hours, with two doses of opium 
of one grain each, with entire relief to the pain and fever. When the potesh 
was reduced to drachm doses, nausea ar d vomiting followed, which were relieved 
by vesication with aqua ammonia, the blister being sprinkled with half a grain 
ef morphine. The patient recovered. Another physician had used the remedy 
te the extent of half anu ounce in twenty-four hours, for three successive days
