LECTURE XLV. 
Turnsick, or Compression on the Brain in the Ox.—Hydatids in 
the Brain of the Ox .— Turnsick in the Dog. , , 
THE act of turning round and round, and always in one di¬ 
rection, is not confined to the sheep. Some rare instances of it 
have occurred in cattle practice, accompanied by the same im¬ 
pairment of sense and consciousness of which I spoke in the 
last lecture as existing in the sheep, and evidently the conse¬ 
quence of partial compression of the brain. A case of it fell 
under my observation in 1829. 
Turnsick in a Cow .—The milk of a cow suddenly decreased in 
quantity; she scarcely ate; rumination was suspended; the muzzle 
was dry; the mouth hot; the hair rough; and the roots of the 
horns hot; the breathing was laborious; the flanks tucked up, 
and mucus mingled with the dung. There was fever without 
any local determination immediately evident. She was bled and 
setoned, and put on a mash diet. When I called to see her on 
the following day, I was told that “ there was something very 
strange the matter with her, for that she was running round and 
round until she became giddy and could hardly stand.’' They 
had placed her in the cowhouse and fastened her up. I ordered 
her to be brought out. There was a peculiar staggering in her 
walk, and her vision was evidently impaired ; the head was pro¬ 
jected, yet held a little on one side; and she was no sooner set at 
liberty than she began to describe circle after circle. I saw 
nothing of the giddiness which had been described to me, but 
she made me giddy by looking at her. 
Difficulties of the Case .—It was a new case to me. I thought 
that 1 had found, what I had occasionally heard of, an instance of 
hydatid in the brain of horned cattle. I pondered for awhile 
what to do. Nothing could indicate to me the situation of the
