CASE IV. — Shewing that these partial or topical Swellings ori- 
ginate in one and the same Disease as the diffuse or general 
Swellings. 
The same brown carriage-horse, whose case (numbered II) 
stands at page 442, experienced, during the springs of 1842 and 3, 
attacks of swelling in the legs ; but they were nothing more than 
what the groom — knowing his “ constitution” — was able to over- 
come by cathartic and diuretic medicine, and exercise. 
This spring (1844), however, he has again entered my list for 
a similar but greatly more severe attack to what he suffered in 
1841. He has, during the early part, been in the country, away 
from the groom, and has not, as he says, received that attention as 
to physic and exercise and diet which he finds it necessary to pay 
to him, and to the neglect of which he ascribes his present malady. 
On the 11th of May, of the present year, the horse, having been 
but a short time out of the country, was brought to the infirmary 
about noon with every appearance of being very unwell : he was 
breathing quick, had his nostrils dilated, lining membrane red- 
dened, an excited countenance, hot mouth and skin, and accele- 
rated pulse. The impression produced by the symptoms present 
was, that the attack was bronchitic; and, in accordance with that 
notion, a gallon of blood was immediately abstracted, an aperient 
given, and the compound terebinthinate liniment rubbed upon his 
breast and throat. 
14 th. — Yesterday he was very much better, his disturbed 
breathing having left him; and to-day he is so much recovered, 
that I ordered the groom to lead him out of his box for a little 
fresh air and exercise. Scarcely, however, had he commenced his 
promenade, when the groom returned with him, saying he found 
him shewing lameness in the off fore-leg. I examined the limb, 
and found a circumscribed ovoid tumour upon the inner side of the 
arm, warm to the feel, and very tender on pressure, solid and 
firm, and not pitting. “ Oh !” exclaimed I immediately, “ why 
your horse has got his old complaint again ; — the same disease he 
had in the spring of 1841.” Here was a metastasis, and a quick 
one, from the mucous membrane of the air-passages to the sub- 
cutaneous tissue of the arm. I must alter my therapeutics. Let 
him lose another gallon of blood, and take afterwards a drachm of 
calomel in nine drachms of cathartic mass ; have his diseased limb 
plunged into a warm bath, and take walking exercise twice a-day. 
1 5th. — The tumour is increased in size, being now the bulk of 
the half of a small pumkin. It is warm and painful. Let a wet 
bandage be kept rolled round the arm in the absence of the fo- 
mentation.
