without any enlargement of the submaxillary glands, half an ounce 
of the flowers of the arnica were given twice a-day, which dose 
was on the three following days doubled, trebled, and quadrupled, 
without effect. By way of a finale, on the fifth day, fifteen ounces 
were administered at one dose, and still no result. 
Arum or Wake Robin. 
{Arum Maculatum.) 
CASE I. — September , 1812, to a glandered horse, shewing signs 
of farcy in his legs, two drachms of the recent root of common 
arum were given in ball twice a-day, chlorine at the same time 
being liberated under his nostrils, which were both ulcerated, and 
profusely discharging. On the third day the dose was augmented 
to half an ounce. On the fifth, the patient took an ounce morning 
and evening. This produced symptoms of fever, much increased 
his pulse, and took him off his appetite. Next morning an in- 
voluntary spasmodic sort of twitching of the muscles of various 
parts was observed, particularly of the side. On the seventh 
day, his appetite having returned, one dose of an ounce was given. 
Eighth day, one ounce and a half morning and evening. Ninth 
day, found purging very much, and exceedingly ill, in appearance, 
from the medicine, though free from pain. Tenth day, died sud-

CASE II. — October , 1812, a remarkably large, healthy-looking, 
strong bay-horse, five years old, in fair condition, having a small 
ulcer visible within the off nostril, from which there is some dis- 
charge, with enlargement of the submaxillary lymphatic gland of 
the same side, was subjected to the action of recent arum root.

3 d . — Give nine drachms twice a-day. 
4 th. — Refuses all food — pulse 60, and small — heaves slightly at 
his flanks, and is tucked up — extremities cold : for all this, how- 
ever, the horse has a sprightly look, evinces nothing like nausea, 
nor are his bowels affected, his dung being in hard balls. 
5th. — A rowel was inserted under his jaw, but no medicine 
given — he still continuing off his feed. 
(5th. — Let him take half an ounce, boiled in oatmeal gruel. 
7 th. — The drench has taken him again off his feed. 
8 th. — Hangs his head, looks dejected, but his countenance ex- 
presses no pain, nor is there any sort of uneasiness about him. 
9 th. — Repeat the drench morning and evening. A strange mor- 
bid granulative action appears in the ulcers in the nose ; the gra-
