EXTRACTS FROM FOREIGN JOURNALS.

rounded piece of bone, and the pressure produced by the 
foreign body upon the oesophageal mucous membranes, 
added to the fermentation of the food and saliva arrested in 
the canal, had given rise to a complete gangrene of the mem¬ 
brane. Notwithstanding this complication, the operation, 
followed by repeated phenicated washes, resulted in a rapid 
cicatrization, and after three weeks in a complete recovery. 
The subject in another and similar case was a street dog, in

lesions. A similar operation, with the same antiseptic pre¬ 
cautions, was followed with the same result.— Ibid. 
BLISTER OINTMENT WITH CORROSIVE SUBLIMATE. 
By Director Degive. 
Taking into consideration the peculiar vesicating and 
alterative properties of the bichloride, the author recommends 
the following mixture for the attainment of the desired 
results: of sublimate and pulverized cantharides, equal parts; 
15 grammes for a strong mixture ; 10 grammes for one of or¬ 
dinary strength ; both thoroughly mixed with 100 grammes 
of vaseline. Directions for use : shave the hair from over the 
part where the application is to be made; rub the ointment 
well in for ten minutes; six hours after, lay over it a single 
layer of the ointment. The maximum of strength is exhausted 
after twenty-four hours. However severe the effect may be,

UPON THE DIAGNOSIS OF TUBERCULOSIS BY EXAMINATION OF 
THE OCULAR HUMORS. 
By M. L. Manderau. 
Early diagnosis is one of the principal points in veterinary 
practice, and sometimes equally desirable and difficult, but 
the observations of the author seem to promise the removal 
of a large portion of the difficulty, if not in all, in at least a 
large proportion of cases, whatever may be the extent of the 
lesion, or its location in the diseased animal. According to
