A CASE OF APOPLEXY, CONNECTED WITH 
A SIX-YEAR-OLD cob-mare, belonging to Mr. T. Bowman, of 
Stonfield Street, quite spirited, and in good husbandry condition, 
was put to the thrashing machine on the 21st Oct. 1839. Having 
worked about two hours, she had a few minutes’ rest, and, soon 
afterwards, recommencing her labour, was observed to falter and 
be giddy. She was immediately led staggering to the stable: 
she pushed forward to the rack; seized and ate a few mouthfuls of 
hay, and fell backwards prostrate in the stall, in which posture she 
continued without power to move the limbs, although she tossed 
about her head for some time. 
About four quarts of blood were abstracted, and, three hours 
afterwards, when 1 arrived, coma with complete paralysis had su¬ 
pervened. The external muscular system was flaccid, insensible, 
uncontrollable, and shook with a violent tremor, which had com¬ 
menced soon after falling. The external temperature was natural, 
but the mouth and breath were extremely hot; the tongue was dry, 
soft, and hanging out; the pulse 65, and strong; respirations 18, 
and irregular. 
The mare came under the owner’s cognizance ten months before 
this, at which time there existed on the right parietal bone a firm 
circumscribed tumour of the size of a nutmeg, but within the last 
five months it had attained that of an orange. She always evinced 
much dread of having it touched. When taken ill this tumour 
was observed to be flattened, and an irregular swelling diffused 
over the ossa frontis, extending to the right orbit. 
The case seemed hopeless, yet I repeated venesection to the 
amount of seven quarts, which softened the pulse, but increased 
its frequency. A cathartic ball was risked in the pharynx, and, 
after some time, swallowed: an incision was made into the tumour, 
and about an ounce and a half of coagulated blood evacuated—in 
which operation a perforation of the parietes of the skull was dis¬ 
covered, which pointed out the source of the effusion and the ir¬ 
remediable nature of the disease. She died an hour afterwards 
without a struggle. 
On cutting off the head an hour after death, several ounces of 
blood flowed from the foramen magnum; and the recently formed 
swelling on the face was found to consist of coagulated blood and 
serum, poured from the tumour by a rupture of the superior part of 
its sac. 
After a cursory survey, I gave the tumour, flap of the skull, and 
brain, to a physician, whose ardour in scientific research laudably 
prompted him to examine them, and favour me with a description 
which I shall take the liberty to transcribe. 
“ The tumour was lined by a strong shining membrane, upon 
which was observed several small tufts or eminences : the tufts, if
