444 SCIRRHOSTTY, WITH ULCERATION OF THE TONGUE. 
was much enlarged ; the dorsum, towards the apex, studded 
with irregular thick-edged ulcers, with very extensive and hard 
bases, which emitted an offensive smell. On the body of the 
organ, to the left of the median line, a fluctuating elevation was 
felt; and, recollecting the directions given by Mr. Youatt in a 
similar case, I made a free incision into it, laying open a cavity 
about an inch in length, which probably contained serum — at 
least, no pus was distinguishable among the saliva, &c. A lotion 
of chloride of lime was directed to be used alternately with one of 
alum, and the animal to be supported with gruel. 
17th . — No better. Apply, two or three times a-day, a solution 
of iodide of potassium with sulphate of copper, and ung. biniod. 
hydr., once a-day, to the skin underneath the jaw and throat. 
The owner soon observed some improvement ; and, by perse- 
vering with these applications, the animal got quite well. 
This seems to prove the utility of the preparations of iodine 
mixed with those of copper, which, in this case, probably acted 
both locally and generally. I have had frequent proofs of their 
value as internal remedies, and also of mixtures of iodine with 
iron, in cattle practice. 
In my last communication, when describing an operation on 
tumours about the head and throat of cattle (vide page 126), it 
should be understood that the first incision should be carried 
through the skin only ; and, in page 127, line 37, the word 
absence should be substituted for “ action.” 
Mr. Relph likewise adds a very important observation, to 
which we solicit the attention of our readers. We give his own 
language : — 
I beg to state that professional engagements, and, more re- 
cently, a personal injury, have compelled me to postpone the pre- 
paration, for The Veterinarian, of some remarks on the 
present Epizootic among cattle, which much resembles that de- 
scribed by Mr. Barlow and yourself — only, the alimentary canal 
seems more implicated ; and, in all examinations after death, ef- 
fusion into the ventricles of the brain was found to exist. 
This fact, viewed in connexion with the general phenomena of 
the disease, leads me to suspect that its real seat has been over- 
looked : and, regarding you as the arbitrator in these matters, 
may I suggest the propriety of requesting your friends who may 
now have the disease under management to pay special attention 
to these points; and thus to furnish you with materials from 
which to draw a true inference how far the nervous systems are 
primarily concerned in the disease.
