PHRENIC HERNIA.

attack, with protracted suppuration of both sub-maxillary 
glands, by which he was greatly reduced ; but, after some 
weeks’ careful nursing and attendance, he seemingly rallied. 
Upon resuming his work, however, he proved to be a very bad 
roarer. Active and varied remedial measures were tried and 
persisted in for weeks without any benefit whatever resulting. 
For some weeks before his death he made much noise during 
respiration even when standing in his stall ; but more so 
when he was down, and also during feeding, for his appetite 
was unimpaired. At times it was quite distressing to hear 
him, the noise amounting to a shriek. Auscultation convinced 
me that it proceeded from his thorax, and I suspected 
bronchial abscess. The noise increasing, and becoming even 
more distressing to listen to ; the animal was removed to a 
distant paddock, with a warm out-house to run in, which he 
had not tenanted many days before he died. 
Post-mortem examination. — There was a rupture of the 
diaphragm, about three inches long, just to the right of the 
oesophageal opening, the edges of which were thickened as if 
of some long time standing. Several feet of the small intestines 
were within the thorax, a portion of which, four inches long, 
was firmly adherent to the pleura, and the}' were strangulated. 
The right lung was absent, the pericardium full of fluid ; but 
the other portions of the respiratory passages were free from 
disease, proving that the noise was caused by the presence of 
the hernia, which I think must have existed for some time. 
Case 4. — Phrenic Hernia accompanied with 
Effusion. 
An aged Suffolk mare, with a foal at her feet, was grazing 
on the farm of the late Duke of Manchester, when she was 
observed suddenly to suspend feeding, and commence rolling. 
Her abdomen, to use a hacknied phrase, was as tight as a 
drum-head. I was at her side in less than half an hour from 
the commencement of the attack ; but only in time to super- 
intend and report an instructive — 
Post-mortem examination . — Upon opening the abdomen a 
large quantity of fluid escaped. On approaching the dia- 
phragm, we found an extensive lesion on the left side, through 
which several feet of the intestines had found their way, 
these lying immersed in several quarts of the same liquor as 
that met with in the abdomen. The mare was a good mother, 
and never had any previous illness. 
Remarks . — I commenced by stating that the cases I have 
thus recorded contained nothing new ; but perhaps they may
