442 CONTRIBUTIONS TO COMPARATIVE PATHOLOGY. 
18f/t. — The cough does continue. After careful watching it 
may be seen once in every eight or ten minutes, although it is not 
often heard. Give six grains of the hydriodate of potash every 
night in a mash. 
22d. — The obscure cough, I do trust, is diminishing. Con- 
tinue medicine. 
27th. — Cough diminishing; continue medicine. 
Aug. 3d. — Discontinue medicine, but watch. 
Sept. 20th. — This animal begins to cough again, and there is 
considerable labour in respiration. Give him two ounces of salts 
in a mash every night. 
26th. — The heaving has increased, but the cause is plain — he 
is rutting. He is in a strangely excited state. There is no dan- 
ger, except that this may so bring him down and weaken him, 
that his old disease, if it still lurks about him, may again appear, 
and bid us defiance. He will eat nothing but hay, and little of 
that. 
He got perfectly well, and continued so several months, when 
he was seized with acute inflammation of the joints : it shifted 
from joint to joint, and he sunk under the irritation it caused. 
The lungs were perfectly sound. 
Tumours — Hydriodate of Potash. 
1834, Jan. LC )th. — Zebu Cow. A considerable tumour has 
suddenly appeared in the channel between the branches of the 
lower jaw. It is very hard, a little hot, and very tender. Fo- 
ment. 
12th. — Not so large, but evidently harder. Still foment. 
1 6th. — The tumour becomes harder and harder. Let it be 
daily well rubbed with the ointment of hydriodate of potash (po- 
tassae hydriod. 3 i, lard 3 vii). 
1 6th. — The tumour is larger, but considerably softer, and with 
more irregularity of surface. Continue ointment, and give five 
grains of the hydriodate daily in a mash. 
1 7th. — The tumour is now diminishing. It is softer, and seem- 
ingly disposed to point at the most dependent part. Continue 
the hydriodate, and the ointment of ditto. 
1 8th. — I lanced the tumour, and at least half a pint of thin 
flaky, grey-coloured fluid escaped. Continue the hydriodate in 
a mash, and also the ointment. 
20th. — The discharge has ceased, and the tumour, although 
smaller, is harder than ever. Continue the hydriodate internally 
and externally. 
2 2d. — The tumour is lessened, but is harder than ever. Con- 
tinue treatment.
