the interval that took place between their administration and the 
purgation, to have primarily set the bowels in action. Nor did 
the tobacco-enemata succeed; for, after about three injections, 
they appeared, as I have noticed in cases before, to lose their 
stimulating power. I believe, myself, that the mercury accom- 
plished the purgation ; and I feel more confidence in thinking so, 
from having, in three or four previous cases, made the same ob- 
servations. Indeed, I begin to think that mercury has been very 
unwisely cast into the back-ground in veterinary medicine. In 
such hopeless cases as the present, and in those, equally hopeless, 
of chest affections, I have, for some time*, myself, made mercury 
my sheet-anchor. 
HARD TUMOUR IN A MARE. 
By A. S. Copeman, V.S., Walpole . 
Nov. 11, 1843, my attention was requested by P. C. Good- 
wyn, Esq., to an aged mare, of large size, beautiful symmetry, 
and in fine condition. It had been observed for some long time 
past that she moved stiffly and awkwardly, as if slightly injured 
in her loins ; frequently she would weave her head, particularly 
after drinking water from the pond, and if sharply corrected, or 
her head suddenly elevated, it produced a general tremor of her 
whole frame, which lasted for several minutes : still she performed 
her work and kept up her condition to last night, without shew- 
ing any other symptoms of disease. 
On examining her this morning, the following symptoms pre- 
sented themselves: pulse 65, full and wiry — mouth injected, hot 
and dry — skin glossy — continually weaving her head, very un- 
easy, frequently walking round her box with a stiff, awkward, 
staggering motion, the whole body in a state of tremor — contrac- 
tions of the muscles of the breast — the right leg frequently 
raised quickly from the ground, stretched out forward at full 
length, and held in that position for some seconds. 
Treatment . — Bleed two gallons, except symptoms of syncope 
should sooner make their appearance. Put her in a cool box, 
apply warm clothing, give in solution Barb, aloes giss, with tine, 
zingib. gj. Have all possible quietness about the stable. 
6 o’ clock, p.m. — She appears in every respect as reported in 
the morning, except that the pulse is more accelerated, the 
pupil of the eye dilated, with intolerance of light. Bled to 12
