with yellowish sticky covering. A large mass as big as two 
fists filled the cavity of the bladder. The cord and the tail of 
the horse were examined by Prof. Cadeac, who found “ that the 
cord, on a level with the sacral pairs, presented an enlargement 
in the form of a tumor which must have filled the entire rachi- 
dian canal. The cord was dense, firm, hard, fibrous, looking 
like a fibroma developed in the medullary canal. In front of 
this tumor the cord was softer and more anteriorly resumed its 
healthy appearance. The case was for Prof. Cadeac a clinical 
type of sclerosis of the cauda equina.—( Journ . de Zootech .) 
Intestinal Obstruction in a Mare—Taxis after 
Puncture of the Vagina—Recovery [By M. Audeberi ].— 
This animal was taken with colic, due to intestinal obstruction, 
which lasted for five days and failed to be relieved by all kinds 
of treatment, blood-letting, injections of pilocarpine, glycerine 
injection, frictions of turpentine and even the injection of 4 c.c. 
of a solution of chloride of barium, which had previously given 
some excellent results to the author. Considering the animal 
lost, the owner gave it to the author, who thought to resort to 
vaginal puncture to reach the obstruction. The vulva and 
vagina were disinfected, and with a bistoury cache the vagina 
opened as for ovariotomy. With the hand introduced into the 
abdominal cavity, the floating colon was felt and a torsion of its 
circumvolutions was felt. At all hazards, the intestinal mass 
was pushed about, pressure was made upon the hard faeces which 
were collected in it, the twist of the colon became untied and 
the obstructive collection gradually pressed into the rectum. A 
second dose of barium brought an abundant evacuation. After 
a few days of careful diet, the animal returned to work. 
ITALIAN REVIEW. 
Phalangeal Exostosis [By M. Bamba and Bobbia ].— 
According to the authors, ringbones are due to four principal 
morbid processes : (1) dry deformans arthritis ; (2) periostitis, 
due to a sprain ; (3) periostitis due to traumatism or wounds by 
extension to the periosteum of the inflammation existing on the 
skin or in the subcutaneous tissue of the phalanges ; (4) rachitic 
diathesis. The prognoses of these different forms vary accord¬ 
ing to causes : the first are difficult to relieve ; those due to 
periostitis may disappear by removal of the original cause, the 
last are also amenable to treatment. A preventive treatment 
consists in proper shoeing. The curative treatment varies with
