CHRONIC GLANDERS. 4 S3 



and involve the pharynx and larynx. If the practitioner 

 meets with a case he is doubtful of, he should explain to 

 the owner of the animal his suspicion that the case is one 

 of glanders, and the animal should at once be isolated 

 in such a manner as to have no communication whatever, 

 either directly or indirectly, with any other animal, in addi- 

 tion to which a debilitating course of treatment should be 

 adopted— as, for instance, a full dose of cathartic medicine 

 may be administered, when, as a rule, the symptoms be- 

 come better marked, the disease increases in violence, and it 

 becomes plain that the case is one of glanders ; or some of 

 the nasal defluxion may be obtained, and the animal inocu- 

 lated on the hind leg, when, if the case be one of glanders, 

 farcy will probably appear in a few days as a result of the 

 inoculation. This test, however, while one of the most 

 reliable that can be applied, should not be considered as 

 infallible. As previously stated, there are cases in which 

 the ulcerated patches are not visible, but the leg swells 

 without any visible cause ; and this symptom, taken in con- 

 nection with the presence of a slight nasal discharge, should 

 be looked upon with suspicion. An animal maybe under the 

 practitioner's observation for years, and be affected during 

 the whole period, without ever being suspected ; the animal 

 may appear to be suffering from debility, and nothing more. 

 A case has been recorded of a number of horses in a certain 

 stable dying every j^ear of glanders, without anyone being 

 able to explain in what manner the disease was contracted ; 

 finally they killed an old animal showing not the slightest 

 sign of any disease other than general debility, and made 

 a post-mortem examination, which revealed the presence of 

 the characteristic lesions of chronic glanders. To be more 

 certain, virus was ol)tained from the body and used to 

 inoculate other animals, in which, as a result, the disease 

 was produced.
