15(3 CONTRIBUTIONS TO COMPARATIVE PATHOLOGY. 
18th. — The discharge and the tumours lessened. Continue 
treatment. 
21sL — The appearances of improvement are delusive. The 
discharge is greater than ever ; it begins to have a peculiar half- 
acid, half-fcetid smell ; it is thin, of a dirty grey colour, and 
corrodes more and more. I dare not apply a wash that would 
give pain. Fomentation and medicine. 
25th. — She is evidently getting thinner and weaker. Treat- 
ment as before. 
28th. — The emaciation continues. Omit the medicine, but 
continue the fomentation. 
March 4 th. — Little change, but increased emaciation. She 
will no longer bear handling. 
8th. — Tumour decreasing, but she is sadly thin. 
16^/j. — S he will once more submit to a little handling. Try 
whether a little green elder ointment can now be applied ; it may 
allay irritation, and prepare for something else. 
20th. — The ointment has been applied ,* the parts are cleaner, 
and some of them a little disposed to heal. Repeat ointment; 
coax to eat, for she is rapidly losing flesh. 
22 d. — Mr. Owen met me in consultation respecting the poor 
animal. It was determined that the iodine had had a fair trial, 
and had failed, and that, as a matter of experiment, the hemlock 
should be tried ; but that she should have two or three more days 
exemption from medicine, in order that she might somewhat 
recruit her strength. 
27 th. — The tumours are once more beginning most rapidly to 
increase ; they are hot and tender, and the discharge is immense, 
and mixed with blood. She is much depressed, and evidently 
suffering. 
30^.. — The tumours are as large and discharge as much as 
they did, but her countenance has brightened, and her appetite 
returned within the last three days, so that I am unwilling to ha- 
zard the disappearance of these most favourable symptoms by the 
application of the hemlock. Leave her for a day or two. 
April 5th. — These appearances also were delusive ; her appe- 
tite is gone, and she is wasting every day. Mr. Langstaff kindly 
gave me his advice with respect to her. He was anxious that 
the tumours should be deeply opened, and Mr. Liston, who saw 
her on the same day, expressed the same opinion : but then 
came the question, how? by what means could she be sufficiently 
confined. The head keeper was sent for, and he and myself 
gave it as our opinion, that, without extreme danger to the helpers, 
and the certainty of some mischief being done, it could not be
