Mr. Walley then read the following account of a case of tumour 
at the base of the brain, accompanied with effusion;— Subject: 
A grey cart-mare, seven years old, very fat, always employed in 
farm work.— History : From three to four weeks previously to my 
attention being directed to the case, her owner suddenly died from 
a cause which necessitated his speedy burial; in order to collect his 
friends together for that purpose, the son put the mare in a light 
vehicle, and drove her a long round at her highest speed, the day 
being one of the hottest experienced in the late very hot season. At 
the time of this journey and afterwards she was engaged in reaping 
corn with a machine; she perspired freely after her journey, and 
was very dull, the attendant, of course, thinking it was due to 
exhaustion. From this period she never recovered her former 
spirits, and it was with difficulty she was made to do her work; 
This was attributed to laziness, from the hot weather. On the 20th 
of August I was requested to examine and treat her. I was 
informed that the symptoms then presented had been gradually 
developing themselves for some few days.— Symptoms : So far as 
pulse, breathing, colour of the membranes, excretions, &c., there 
was nothing to indicate ill-health ; the appetite, however, was very 
bad; she was partly unconscious, and on being made to move did 
so with an uncertain gait, and showed great inclination to peram¬ 
bulate the box, invariably turning to the right, rubbing the left side 
against the wall as she progressed; on pressure being applied to 
the poll and to the base of the ears, considerable tenderness was 
evinced.— Diagnosis : Pressure on the brain from abscess, tumour, 
or water.— Prognosis : Very unfavorable.— Treatment: Perfect 
quietude; counter-irritation to poll and base of ears ; laxative 
medicine, which latter operated more freely than was desirable; 
offer her small quantities of grass, mash, scalded hay, &c., fre¬ 
quently.—August 21st and 22nd: Decidedly better in every respect; 
bowels responded freely ; counter-irritants acted powerfully ; gave 
a slight stimulant and sedative combined, twice a day.—23rd: 
The symptoms had returned with great violence, and she had 
bruised herself considerably, but still lay down at intervals. I 
immediately bled her (the owner had also done this previously to 
my seeing her) ; inserted a seton either side the poll, and gave her 
one or two doses of calomel and opium ; but feeling assured that 
treatment would be thrown away, I did nothing more afterwards 
than attend to her general comfort. She continued to get worse, 
and about ten days after, I was requested to go and destroy her, 
which I did.— Post-mortem : All the organs of the body beautifully 
healthy. The cranium was opened carefully; the vessels of the 
brain were somewhat congested, and there was a considerable 
amount of effusion into the cranial cavity. On removing the brain 
a small tumour, about the size of a hazel nut, w'as revealed to view, 
situated on the floor of the cranium and adherent to the anterior 
part of the os sphenoides, a little anterior to the sphenoidal hiatus. 
The tumour appeared hard and sarcomatous, but upon opening it 
it contained a small quantity of fluid.— Conclusions : The tumour
