struction of the alimentary canal. The patient soon grew worse 
and died. At the post-inortem the stomach contained but little 
hqmd the intestines empty. In the thorax, the pleural cavities 
were filled with fluid of a peculiar color, and the oesophagus was 
found considerably thinned and dilated by a mass formed by 
bones, one of which had perforated the oesophagus and allowed 
the fluids given to the animal to drop into the pleura. To all 
appearances the trouble was of old date.— (Ibid.) 
Curious Case of Recovery in a Cribber [By Mr. J. 
Maleffe\ . A horse was severely affected with cribbing, con¬ 
stantly sucking wind. One day he started for a good run, and 
as he was to be arrested, he met with an obstacle, and fell 
down with a somersault which resulted in a luxation of the 
fourth cervical vertebra. Unable to get up, he remained lying 
36 hours, and was considered as good as dead. The author made 
some attempts to reduce the luxation and succeeded. From that 
moment an improvement became manifest, the animal began to 
move his head, got up and tried to eat. But the most interest¬ 
ing fact is that from that moment he stopped cribbing. This 
fact seems to prove that the etiology of this bad habit depends 
on the pneumogastric and the sympathetic.— (Rec. de Med. Vet.) 
Nervous Troubles Due to a Chronic Disease of the 
Diver—Biliary Dithiasis [By M. Averons].— A case of unu¬ 
sual interest is recorded by the author in the Revue Veterinciire de 
Toulouse in relation to a horse which presented all the symptoms 
of a general comatose condition, now and then interrupted by man¬ 
ifestations of rage, which made him take hold of and bite his stone 
manger, upon which he tore all his gums 5 some colicy pains 5 mic- 
turation difficult 5 locomotion imperfect, automatic 5 his respiration 
slow, the pulse accelerated and strong, the temperature 38.8° C. 
Under suspicion of cerebral congestion, he was placed under 
treatment, which seemed to give him so much relief that he was 
about to be considered as convalescent, when all of a sudden the 
symptoms assumed a new and more severe form, which ended 
by death in convulsions. At the post-mortem among the nu¬ 
merous lesions found in the intestines, the stomach and the per¬ 
itoneum, the liver presented organic changes and also a dilata¬ 
tion, a tumor of the choleduc canal, which contained a large cal¬ 
culus, weighing 258 grammes (over 8 ounces). The divisions of 
the biliary duct were filled by thousands of little calculi. The 
kidneys were enlarged, the heart somewhat hypertrophied. The 
cerebro-spinal axis and its membranes were healthy. In resum¬ 
ing the conclusions of the well-described symptomatology and
