form. Even the foal has been known to suck the disease from 

 its dam. 



" Moreover, experiment has been had recourse to, to inoculate 

 for strangles. 



"M. Damalix smeared with & sponge impregnated with mat- 

 ter taken from the abscess of strangles, twice daily, both sides of 

 the pituitary membrane and the internal surfaces of the linings of 

 the eyelids, in a sound horse, about to be cast for spavin. Thi3 

 was continued for seven days. On the eighth, he remarked, the 

 horse had lost his appetite, had commenced running from both 

 nostrils, coughed softly and loosely, had swelling under the jaw, 

 which ended in resolution ; all the symptoms terminating eight 

 days from their commencement. 



" It has been remarked that strangles is more surely communi- 

 cated at an early than a late stage, and in a certain form more 

 readily than in others. Strangles will assume the herpetic char- 

 acter, will simulate farcy and glanders, will settle in the mesen- 

 teric glands, or may follow castration. In regard to contagion 

 may be mentioned, as most readily communicable, this form of 

 strangles, which assumes the character of eruptions on the lips, 

 nose, and pituitary membrane." 



BRONCHITIS. 



Veterinarians recognize this disease under three aspects, viz. : 



1. Acute, as when the horse is suddenly attacked with an irrita- 

 ble cough and sore throat, with the usual febrile symptoms, such 

 as quick, wiry pulse ; membranes of the nose and mouth redder 

 than usual; accelerated respiration; great anxiety of counte- 

 nance, &c, &c. 



2. Chronic bronchitis, which sets in after the acute has sub- 

 sided ; this stage is marked by a discharge of watery and some- 

 times mucous fluid from the nose; the act of respiration is 

 performed with 'a sort of wheezing noise, which is caused by ob- 

 struction within the bronchial vessels, either from contraction, by 

 which their calibre is lessened, or else from a thickening of the 

 lining membrane, or, lastly, from the accumulation of sero-mu- 

 cous fluid within their cavities, of which they are somewhat re- 

 lieved in the act of coughing.
