composition. The uterus of the mother was of normal size, and 
on the superior face of the body presented an irregular cicatrix, 
the marks of which are also found on the internal surface, show¬ 
ing that all the membranes had been involved in the laceration. 
No trace of the placenta could be found, neither in the uterus 
nor in the abdomen of the mother. No history of the mother 
could be obtained.— {Rec. de Med. Vet.) 
Fracture of the Sphenoid \M.Drouin\ .—Although well 
protected the base of the cranium is not free from fracture. The 
lesion is due to a traumatism acting at some distance and espe¬ 
cially upon the occipital protuberance. The horse which is the 
subject of this observation frequently had attacks of staggers, 
his work was irregular, and when he was kept in the stable 
several days he would almost invariably fall down suddenly. 
Ordinarily when he fell he would drop on one side, and after 
two minutes could get up. At last, one Sunday morning he 
reared so violently that he fell backwards, the poll striking the 
pavement, blood flowing from the nostrils. In five minutes 
he was dead. At the post-mortem, made immediately, the 
sphenoid was found entirely loose , carrying with it a portion of 
the bacillar process of the occipital ; it "had a perpendicular posi¬ 
tion to its normal direction, and in its displacement had cut the 
internal carotid and cavernous veins of the occipito-spheno- 
temporal hiatus. The posterior extremity of the large bony 
splinter had also entered the rachidian bulb, cutting the pyra¬ 
mids and the pons varolii. The gutteral pouches were filled 
with blood.—( Bullet . de la Soc. Cent.) 
Strangulated Hernia in a Puppy [A. Colin ).—Three 
weeks after birth the little fellow had a hernia as big as a nut, 
but it grew quite rapidly, and in a short time was the size of a 
hen’s egg. At first the dog did not seem incommoded by the 
tumor, but one morning he was taken ill, groaned, and his little 
abdomen became tympanitic. The hernial tumor was hard and 
painful to pressure, was irreducible, and did not give the sensa¬ 
tion of the presence of liquids or gases. An operation was de¬ 
cided upon. The scrotum and vaginal sac being opened, the 
hernia appeared, formed by a loop of the small intestines, and 
presenting on its anterior extremity a gangrenous spot. There 
was another also on the posterior extremity, but it was less ad¬ 
vanced. The intestine was opened and a hard mass formed of 
straw was found. After excision of the gangrenous portion and 
thorough disinfection the wound was sewed up, the hernia re¬ 
duced, and the vaginal sac closed by a circular ligature. Low
