The progress of the morbid process is as follows : (i) a 
sprain (effort) of the desmous apparatus of the surface or depth 
of the small tarsal joints ; (2) an osteitis and osteo-periostitis, 
first rarifying, then condensing, of the bony pieces affected or 
of those surrounding, which receive too heavy percussion in loco¬ 
motion ; (3) an ankylosis at the periphery, sometimes not 
difformans, but ordinarily granulating and encircling ; (4) a 
dry arthritis, ending in solid central ankylosis or progressive 
osteoporous difformation with eburnation of the diseased artic¬ 
ular surfaces. 
For Mr. Barrier, spavin is not hereditary. It is the bad 
formation of the hocks which predispose to it.

Congress of Tuberculosis. —As I announced in a pre¬ 
vious number of the Review, the fourth Congress for the Study 
of Tuberculosis was held in Paris from the 27th of July to the 
2d of August. The attendance was very large and the veteri¬ 
nary profession well represented, not only from France, but 
from Denmark, Germany, Switzerland, Italy and even America. 
From that country Dr. Schweinitz, of Washington, was to 
present papers relating to the matters in discussion. He had 
made all his preparations to leave New York by the doomed 
French steamer La Bourgogne^ when at the last moment he 
was informed that he could not be spared from his work at the 
Bureau of Animal Industry. A few days later, the noble steamer 
.met with the terrible accident which put so many in mourning. 
Dr. Schweinitz had a narrow escape. 
The Congress was presided over by Prof. E. Nocard, who 
filled the duties of the position with great success and who car¬ 
ried the honors of applause at the various communications that 
he presented. Prof. Bang, Prof. Arloing, as veterinarians, drew 
.much attention on matters of importance and interest in a vet¬ 
erinary point of view. Out of the seven special secretaries ap¬ 
pointed to record the doings of the Congress, four of them were 
veterinarians.
