EXTRACTS FROM EXCHANGES. 
upper rupture was 5, while the lower was 25 cm. long. The 
thoracic cavity did not contain any free blood ; the lungs were 
filled with blood to their highest capacity. The apex of the 
heart passed out through a slit of the pericardium. The slit 
was on the anterior surface of the heart, and extended on its 
whole height. The edges were slightly reddened ; the serosa 
was normal ; the pericardium did not contain any blood. Cor¬ 
responding with this slit the wall of the left ventricle was 
ruptured in two places, but did not extend through the whole 
thickness of the heart muscle. Their length was 4-5 cm. They 
began at the height of the auriculo ventricular groove, extend¬ 
ing downwards, toward the apex of the heart. The muscles of 
the heart were somewhat of a diffused color, the ventricular 
wall appeared to be thickened, and the endocardium and valves 
were intact. The anterior sharp edges of the ribs, especially 
the one of the 4th rib, extended into the thoracic cavity. Just 
at the height of the anterior sharp edge of the 4th rib were 
the slits in the pericardium and heart muscle. B. thinks that 
the ruptures in the diaphragm were due to extreme strain in 
pulling. In explanation of the ruptures of the heart muscle he 
says that the somewhat hypertrophied and degenerated heart 
labored very hard during the exertion, by which it reached the 
thoracic wall, and as to being struck with the fork, the anterior 
edges of the ribs were directed into the thoracic cavity, and 
during a state of systole of the heart this was cut on the sharp 
edge of the rib. B. observed a similar case in which the ribs 
were intact after a collision with a shaft. The heart in this 
case was totally ruptured.— (Rec. de Med. Vet.)

Paralysis of the Radial Nerve P'ollowing Suppura¬ 
tive Adenitis of the Axillary Lymphatic Glands in a 
Dog \_By J. B. Scoffie and E. Seres] .—This dog was six years 
old, and had been treated for some time on account of lameness 
of the left fore leg. He had had an intermetaearpal fistula of 
the paw of that leg due to some foreign body, of which he had 
recovered. His condition at the time he was brought to the 
authors was such that treatment was not advisable. He was 
very lame on walking, running on three legs, the antibrachial 
muscles being atrophied, the olecranon muscles very much so, 
and remaining insensible to an interrupted electric current. 
The diagnosis of the paralysis of the radial nerve was made,
