place; there was loud and repeated borborygmus. The horse 
laid down frequently and assumed the dorsal position, in which 
he seemed to have some relief. A few hours before death, the 
symptoms seemed to subside, but it was only the precursor of 
death, which took place soon. At the post-mortem, besides the 
lesions of volvulus, there was found a rupture of the stomach on 
its anterior face, which presented the characters of a lesion which 
had taken place after death.— {Jour^i. de Zootechnie^ Sept, ’p 7 *) 
Cardiai, Dilatation with Insufficiency of the 
Orifices—Rupture of the Posterior Vena Cava. —In 
the October number of the Jottrnal of Zootechnie^ of Dyon, Prof. 
Cadeac reports minutely an interesting complicated case of heart 
hypertrophy, in which the organ weighed 6 kilogrammes (12 
pounds), and, while it had doubled in weight, it had trebled in 
size and in capacity. The auriculo-ventricular, the arterial 
openings of the base of the ventricular mass, and that of the 
vena cava, were considerably enlarged, and, though they pre¬ 
sented no marks of inflammation nor any growth, they were in¬ 
sufficient and the closed wrist could be introduced through 
them. The diameter of the veutricles was in proportion to that 
of the openings and the auricles presented also* similar altera¬ 
tions. The arterial system and the venous network of the 
posterior part of the body were entirely empty ; but in the an¬ 
terior part, the venous system was largely developed and in 
appearance doubled in size. The kidneys and liver, enormously 
large, were gorged with blood. At the poiut of eutrance of the 
posterior vena cava over the anterior face of the liver there was 
a laceration involving both the vein and the hepatic substance. 
The animal, aged nine years, was in good condition, used for 
comparatively light work, and had preseuted for some time evi¬ 
dent symptoms of cardiac affection, such as difficult respiration 
on the slightest exertion, acceleration in the beatings of the 
heart, jugular pulse, characteristic bruits at auscultation, threat¬ 
ening asystolic phenomena, oedematous swellings of the ex¬ 
tremities and dependent parts of the body, loss of appetite, of 
flesh and marked signs of hydrothorax and ascites. 
The Influence of the Nature of Foreign Body in 
THE Intestinal Obstruction of Dogs \^By Mr. A. Morey\, 
—An eight-months old Danish pup has the bad habit of picking 
up and swallowing every piece of cord that he meets. One day 
he refuses his food, is constipated, and vomits frequently. He 
is in bad condition, the mucous membranes are pale and some¬ 
what yellowish, the abdomen is tympanitic ; there is much
