CHRON IC BRONCHITIS. 
251 
French-shod horse is furnished with a couple of stout lateral de- 
fences, between which it is raised up out of the way of blows and 
pressure. At the same time, I believe that a dry and hard, or 
“ rigid” hoof, and, in particular, a rigid frog, materially adds to 
the danger of having this disease produced : the elastic hoof and 
spongy frog, in the flat weak foot for example, yielding under the 
infliction of blows and pressure, so as for a length of time, for 
always, perhaps, to counteract any harm that might accrue from 
their being fixtures, and which, I believe, does result from that 
circumstance. I am of opinion with Mr. Turner, that an “ evil” 
accrues from keeping horses standing so many hours in the stable, 
and from the irregular work they are in consequence apt to be put 
to ; and this evil, I repeat, mainly consists in the hoof, during 
that time of confinement in the warm stable, acquiring a rigidity 
which unfits it for yielding under pressure simultaneous both from 
above and from below ; and the consequence is, or is likely to be, 
bruise or lesion, or irritation excitive of navicularthritis. And this 
I should take to be the usual or common way in which this tristful 
disease has its beginning. 
CHRONIC BRONCHITIS, WITH DILATATION OF THE 
HEART AND CARDITIS, IN AN AGED MARE. 
By *, Jersey. 
The present case is the last of five which has fallen under my 
notice since my residence in this island (Jersey). She was a light 
grey cart mare, of handsome shape, the property of G. De St. 
Croix, Esq., a native resident. This gentleman purchased her 
about four months ago, a little touched in her wind, as was supposed, 
she having at that time cough with hurried respirations : so little 
was she affected by it, that labour seemed rather pleasure than 
pain to her. 
I was summoned to attend at the farm, which is a couple of 
miles from town, on the 2d of last month (March), to see the grey 
mare, which was said to be off her appetite, and blowing hard. 
The symptoms which presented themselves to my view were 
these: viz. hurried and rather laborious breathing, numbering 
twenty-four per minute — often sighing — breath warm — mucous 
membranes a little injected — nostrils slightly dilated — pulse 52, 
but of a character not easily described : it was neither a quick, hard, 
full, nor wiry pulse, but one of a languid, irregular, dragging-on (if 
I may be allowed such a term) character, denoting evidently not 
merely functional but structural disease of some important viscera 
of the chest (it was not of an inflammatory state, by any means).
