Treatment. — Bleeding, sinapisms, 5 ounces of alcohol, mashes and 

 milk. 



Next day the temperature was 39*9*^ C, respirations 30, pulse 63. 

 The animal was depressed and sleepy. Nevertheless it took milk and 

 hay tea, to which alcohol had been added. 



On the 9th a tubal murmur could be heard on the right side. The 

 heart-beats were violent and audible on either side. Temperature 40*7° 

 C, pulse 64, respirations 32. Sulphate and bicarbonate of soda were 

 further prescribed. 



On the loth and nth the animal was more depressed ; it could 

 scarcely stand, and appeared as though suffering from laminitis in the 

 fore-feet. 



On the 1 2th these signs of weakness and of congestion about the 

 feet had disappeared. The pneumonia was undergoing resolution. A 

 moist crepitant rale could be heard. Temperature 38'5° C. 



On the 13th the heart became intermittent, pauses occurring after 

 series of four to twelve contractions. All treatment was stopped. 



On the 14th intermittency was more frequent. Of five pauses, four 

 usually occurred after a regular series of four pulsations, the fifth after 

 an irregular series of two to eight. 



On the 1 6th the pauses were less numerous. They became less and 

 less frequent until the animal left hospital.

 horse, by Professor Stockman, appears in the Journal of Comparative 

 Pathology and Therapeutics for 1894, p. 138.] 



HYDATID CYST OF THE HEART. 



72. An eight-year-old Percheron gelding, which had died suddenly 

 during work on the 9th August, 1893. The autopsy was incomplete, 

 but the heart was sent to us as it exhibited peculi'ar changes. 



It was of large size, and towards the centre of the left ventricular 

 wall showed a swelling as large as a turkey's Q^g, yellowish white in 

 colour, the surface marked — especially towards the periphery — with 

 fine vascular branchings. The swelling was uniform, fluctuating, and 

 thin-walled. 



Incision gave exit to a serous liquid containing in suspension a few 

 whitish flocculi. Though for the most part smooth, the wall of the cyst 

 was irregular in places, marked with slight depressions and promi- 

 nences. Microscopic examination of a scraping from the internal surface 

 showed scolices and numerous hooks. The wall was formed of two 

 distinct membranes somewhat loosely united : the external, forming 

 the hydatid membrane or cuticle, exhibited a number of caseating and 

 calcified patches ; the internal, or germinal membrane, was greyish in 

 colour, thin, and very delicate. 



The cyst measured three inches and a half in greatest length, and 

 two inches and three quarters to three inches in diameter. It pro- 

 jected above the surface of the ventricle to the extent of more than an 

 inch. Two thirds of the thickness of the wall of the ventricle were 

 destroyed, so that the muscular tissue, which should have been nearly
