ON GASEOUS EFFUSION IN THE THORAX. 503 
toms were presented. Respiration rather quick and stertorous— 
pulse ninety, and hard—extremities cold—pupils slightly dila¬ 
ted—with an abundant flow of saliva from the mouth. There was 
an emphysematous swelling extending from about the fifth 
cervical to the twelfth dorsal vertebra, and as far down as the 
olecranon on the left and the coracoid process of the scapula on 
the right side. The same tumefaction was seen about the lips 
and around the orbits of the eyes. The tongue was slightly 
swelled, protruded, and of a bluish cast; the head was stretched 
out to its utmost extent, seemingly to facilitate respiration (this 
led the owner to the belief that she was affected with cliers ); 
there were two or three foetid motions, of a pultaceous consist¬ 
ence, in the course of the day, two laxative draughts having been 
administered previous to my attendance. 
Venesection Ibx, magnes. sulph. ^xvi. She appeared very 
much relieved from the bleeding. A powder of nit. pot. et. 
antim. tart, was then ordered to be administered in gruel in the 
evening. There not being any inclination to partake of food in 
any form, thin gruel was frequently poured into her with a 
horn. 
3J.—Symptoms much the same as the previous day, but the 
pulse rather smaller, and the emphysema extending. The 
cathartic drink was repeated. 
4tth .—Bowels freely opened—pulse at the submaxillary nearly 
imperceptible. A blister was applied to the throat, which rose 
well, but without affording any apparent relief. 
^th to the Sth .—Repeated doses of sulphur and gentian 
were administered, with gruel enemata. 
^th .—Gradually sinking: the emphysema has now become 
universal, every part of the surface of the body being affected, 
with the exception of a few inches at the extremity of the tail. 
She died on the twelfth. 
Sectio cadaveris, three hours after death .—On removing the 
skin the subcutaneous cellular tissue presented a yellow aspect, 
and felt like blown veal. On dissecting away the parietes of the 
abdomen, the cause of the laborious respiration was evidently 
manifested; the anterior part of the rumen, bounded by the 
diaphragm, was firmly adherent to that muscle, and presented a 
gangrenous appearance. The stomachs and intestines were now 
removed. No particular marks of disease were perceptible in 
the rumen, with the exception of the abovementioned part, 
which was much thickened and softened, and quite black. It 
was easily lacerated with the fingers. The whole of the stomachs 
were loaded with half-digested food, which shews the necessity 
of active purging in cattle. The interior of the abomasum was
