ON FUNGUS FLEMATODES. 
enlarged, and somewhat tender, it now most rapidly increased 
for three or four days, at the expiration of which period her 
appetite began to fail, her hind legs to swell, and it was re- 
marked that she stood up all night. This position she maintained 
until her death. 
A considerable aggravation of all the symptoms took place in 
the night between the ninth and tenth days. The fungus was 
almost treble its original size, and was highly sensitive — the ap- 
petite was completely gone — she appeared to be labouring under 
excessive and excruciating pain, and her thirst was very great. 
Fomentations were applied to the part, which apparently alle- 
viated her pain, and gave her relief during their application ; they 
were, therefore, continued until the 23d of the present month, 
when a red surface was observed at the inferior part of the tumour, 
which was attributed to the w r ater being applied too hot, and the 
fomentations were consequently discontinued. 
On the morning of the 24th, a large opening with a red pro- 
truding substance was visible ; upon seeing which, the owner 
flattered himself that the tumour would then very soon burst, 
and the mare become relieved thereby ; and what still further in- 
creased his hope was, a profuse and continual discharge of a 
watery fluid, and of a highly offensive smell, from the cyst. These 
symptoms, however, were fallacious, for the substance still fur- 
ther and further protruded — the discharge became still more 
abundant and offensive, so much so, that the litter from having be- 
come completely saturated with the discharge, had frequently to 
be removed, and clean straw put in its place. The edges of the 
cyst became gradually more and more everted, and, in conjunction 
with the tumour, acquired a deeper red colour. Finally, it as- 
sumed a black hue, which was the state I found her in on the 
morning of the 25th. 
The tumour had most rapidly increased, for, when I weighed 
it after her death, it was more than six pounds and a quarter. 
When cut into, which 1 did right through its centre, it presented 
one solid mass, of a dark or gangrenous colour, and of a semi- 
cartilaginous texture, but not one single drop of fluid ; neither 
did I perceive the slightest cavity in its centre in which any 
fluid could have been contained, or any softening of any portion 
of the tumour evincing a probability of any being formed at a 
future period, provided that gangrene had not produced so rapid 
a termination. The tumour was, in figure, almost pyriform. 
Sectio cadaveris . — My first object was to ascertain, if possible, 
how far the disease had extended ; but here I found a work of far 
greater difficulty than 1 could possibly have anticipated, for in 
some parts— among the tendons of the abdominal muscles for
