tfon failed to detect any disease other than general emaciation. 

 On making inquiries concerning the food, the owner replied, "The 

 colt has been fed on good sweet hay and corn-stalks ever since it 

 was weaned." This was caj^tal food for the poor tiling, provided, 

 however, its stomach had a grist-mill within it; otherwise, it wa« 

 hard fare, and must derange the digestive function, and, ere the 

 eolt has attained maturity, dyspepsia, in either a mil 1 or aggra- 

 yatjd form, has secured a victim. 



Mr, Percr'ALL has defined strangles to be "a diffusible swell- 

 ing under the jaw. The tumor consists in a circumscribed inflam- 

 mation, iiaving all the characteristics of simple phlegmon, attack- 

 ing the subcutaneous cellular substance included between the 

 branches of the jaw, which, in consequence, become gradually 

 filled and distended with effusions of lyraphy and serous matters, 

 acquires a firm and solid feel, tenderness on pressure, and a siinse 

 of unnatural heat. This commonly proceeds to suppuration, end- 

 ing, to all appearances, in a common submaxillary abscess. Now, 

 this, and this alone, constitutes strangles. There are in the oooka 

 a variety of other symptoms described, but they are all concomi-

 inflammation, giving rise to soreness about the throat; reddening 

 and discharge at the nose, and perhaps cough ; tumefaction of the 

 salivary glands, producing pain and difficidty of deglutition; and, 

 lastly, some slight febrile commotion of the system." 



Co7itaf;iousness of Strangles. — We learn from the "Veterina- 

 rian '" that M. Heynal, clinical professor at the Alfort School, 

 submits a number of observations corroborative of the contao-ioua 

 character of strangles. He states that " young horses having 

 strangles, and put into stables with horses of adult age, doing 

 their duty, have communicated the disease to those of the latter, 

 who have «*tood in adjoining stalls, though some few have only 

 exhibited the disease in a catarrhal form. Even the fojil has been 

 known to suck the disease from its dam. Moreover, experiment 

 has been had recourse to to inoculate for strangles. jNI Damalix 

 smeared with a sponge, impregnated with matter taken from the 

 abscess of strangles, twice daily, both sides of the pituitary mem- 

 brane and the internal surfaces of the linings of the eyelids, in a 

 sound horse, about to be cast for spavin. This was continued for 

 leven days. On the eighth, he remarked that the horgp had lose
