368 The Management and Diseases of the Dog. 
.the right auricle was united to the large plug by a partially 
fibrinous clot of blood. In the roots of the portal veins 
similar deposits were present, and there was more hyper- 
trophy of the areolar framework of the liver, the lobes of 
the latter being united by a thick layer of lymph. Within 
the pulmonary artery there was also a large fibrinous clot. ° 
The lungs contained large clusters of the same granular 
material found in the auricle and vena cava. 
Mr. Kettle informed me the dog had been in his posses- 
sion for seven years, that he was his first master after his 
breaking, and that he had shown no signs of illness until six 
months previous to his consulting me, and the previous 
season he had galloped the hills as well as ever. The fost- 
mortem examination, however, did not verify sound health so 
shortly before death. Doubtless many symptoms of indis- 
position were displayed that escaped observation prior to 
the first notice of his owner. 
This extraordinary case is recorded, with an illustration 
of the embolism, in the Lzve Stock Journal for July 13th, 
1883. 
EMPHYSEMA. 
Emphysematous swelling in the dog is usually due to 
the infiltration of air into the connective areolar tissue, from 
external injury. Pulmonary Emphysema is generally 
associated with asthma, and is accompanied by shortness 
of breath, cough, frothy expectoration, feeble husky bark, 
and weak pulse. Auscultation reveals wheezy sounds, 
with more or less cardiac palpitation. (See Asthma.) 
Mr. J. S. Gould, pupil of Mr. E. Hollingham. M.R.C.V.S., 
of Tonbridge Wells, has kindly furnished me with the 
following particulars of an interesting case of Traumatic 
Emphysema :— 
“On January 14th, 1888, we had the dead body of a 
deerhound bitch, the property of the Marquis of Aber-
