Among the cases/ which have occurred during tho past month, 
those of disease of the brain may be noticed as possessing some 
interest. One of these occurred in a young mare, rising four 
years old, belonging to a farmer near town, who brought her here 
in consequence of having (after being a few days wrought at light 
farm work) become affected with, to him, unaccountable symptoms. 
When made to move, there was extreme irregularity observable in 
the action of her fore as well as hind extremities, but not more so 
in one limb than another, which, during rapid progression, caused 
a peculiar swinging and uncertain gait. The owner was inclined 
to think that the case was one of injury to the spine; and the 
symptoms were very similar, in some respects, to those existing in 
such instances. From the fact, however, that the fore as well 
as hind extremities appeared equally implicated, it was evident 
that the disease existed either high in the neck or in the brain 
itself, most probably in the latter, from the circumstance that no 
injury could be traced in the spine, throughout its whole extent. 
There was not any very appreciable abnormal change in the circu- 
lation, and the respiration was not affected ; the animal also fed 
well, and appeared lively. From the strength of the pulse, and 
(in cases of this nature) from the frequency of disease in the 
choroid plexus and lateral ventricles of the brain, she was bled 
freely, had laxative medicine, and cooling applications were used 
to the head, under which treatment she has continued gradually to 
improve, and is now nearly recovered. The second case occurred 
in a mare purchased, a few days previously to becoming diseased, 
by a coach proprietor. She had been put into the parcel-cart as 
exercise for a few days, before using her for severer work ; and 
one day, while returning from Leith, the driver observed her to 
become apparently languid and weak, at the same time hanging 
her head near to the ground, so that by the time she reached 
nearer home she was with difficulty got into the stable-yard. 
During the time that the harness was being removed, it required 
several men to support and afterwards to assist her into the loose 
box, where she immediately fell down in a state of stupor, in 
which condition we found her, with the pulse 50, and respiration 
natural, but apparently possessing little power in the extremities, 
and quite unable to rise. She was bled freely, had purgative 
medicine administered, and was well packed with straw. She 
remained pretty much in this condition until the following day, 
when, appearing somewhat relieved, she was turned to the con- 
trary side on which she had been lying. This appeared to revive 
her still more, and she seemed to recover, in some degree, the 
use of the hind legs, but was still unable to rise. By the third day 
she had evidently gained strength, and made attempts to raise her-
