permanent or extensive alteration of structure, and Neurotomy is 
adopted as a last resort to palliate or subvert the effects of the 
disease with regard to the animal’s action, I should say such a 
horse can never afterwards become sound, although he may go 
free from lameness for many a year; but, on the other hand, if 
the disease is of such a nature that no particular alteration of 
structure attends it, and Neurotomy is adopted as part of the 
remedial means—as an assistant in the removal of the disease—I 
should say that such a horse might probably become sound, 
and that, therefore, the operation of Neurotomy does not neces¬ 
sarily render an animal unsound. 
I have thus superficially attempted to express the opinions of 
an humble student; and if those opinions be somewhat crude, 
and unfit to bear the test of experience, they are placed where 
the professional opinions of all ought to be, viz. before the public. 
The object of my writing is not to support any particular doctrine 
or theory, but to elicit truth; therefore, if any of your correspon¬ 
dents would remember what Persius says, 
“ Scire tuum nihil est nisi te scire hoc sciat alter,” 
and be at the trouble to point out the fallacy of my remarks, they 
would confer a favour upon me. 
INDIGESTIBLE SUBSTANCES IN THE COLON OF 
A MARE. 
By Mr. Fuller, March , Cambridgeshire . 
On the 5th of February last I was summoned to attend a 
cart-mare, in foal, the property of Mr. T. Ellcott, of March, 
from whom I understood that the mare had just returned from 
her day’s work, and that no alteration was seen in her until she 
had got home. Upon examination, I found her labouring under 
enteritis. I immediately abstracted six quarts of blood, gave her 
twenty ounces of castor oil, raked her, and threw up a gallon of 
warm gruel as an enema; clothed her moderately, and placed her 
in an open shed. I remained with her some hours : she dunged 
several times during the evening, and at night she appeared 
much better. I saw 7 her again during the night, and she seemed 
to be doing well: I horned down a gallon of warm gruel, and 
repeated the enema. The following morning the symptoms had 
returned as violently as ever. I again bled her copiously, and 
blistered the whole surface of the abdomen. Her bowels were 
relieved several times in the course of the day: the faeces were 
of a good consistence, but highly offensive. At night she ap¬ 
peared to mend, and continued to do so until the following
