GLANDERS AND FARCY. 65 



the local swelling referred to by Professor McFad\'eau takes place 

 after the Malleiu has been injected, which swelling has to be 

 measured both as to its length and breadth to determine in con- 

 junction with the rise in temperature, whether the horse is prob- 

 ably the subject of glanders. With respect to the observations to 

 be made with the thermometer, it will be necessary to take the 

 temperature six hours before the injection of the Mallein, at the 

 time of the operation, and every six hours thereafter, until thirty- 

 six hours has expired from the time the Mallein was injected, on 

 which occasions also the measurements of the local swellings must 

 be taken; each of these particulars must be registered in detail; if 

 the register of the temperature shows that the thermometer has 

 risen from loo to 103 degrees or higher, and the local swellings 

 extend an average of five or six inches both ways, then it is pretty 

 safe to condemn the horse as the subject of glanders, and he must 

 at once be isolated; but if during the period of thirty-six hours 

 following the injection the temperature rises onh^ one degree or a 

 fractional part thereof the evidence is not sufficient to warrant the 

 conclusion that the horse is the subject of glanders; the test 

 operation should be repeated a week after. 



It is perhaps hardly necessar}- to state that if the services of a 

 professional veterinarian are available, it is far better to entrust 

 such an one with the performance of the test operation; on the 

 contrary if one is not within reasonable reach, the Mallein should 

 be obtained through some reliable wholesale druggist w^ho may be 

 trusted to obtain the proper agent from the right source. 



The next question that has to be considered is how to form a 

 conclusion from symptomatology that a horse is affected with 

 glanders and to this end we will offer a list of the principal guid- 

 ing 



Symptoms, and to do this satisfactorily it is almost necessary 

 to divide them into two classes, nameh', the acute and the chronic: 

 we shall take the acute first: the temperature will be considerably 

 exalted; the pulse quick and rather soft, the respirations rather 

 more frequent than is usual in health; the coat has a generally 

 unthrifty appearance and feels harsh to the touch, dry and stands 

 up on end; the animal speedily loses condition, and becomes 

 wasted and thin: the urine is rather increased in quantit.v and has 

 little or no color; the mucous membrane of the nostrils is of a
