THE SERUM TREATMENT OF GLANDERS. 603 



living glanders bacilli. The results were similar to the preceding. 

 The disease developed in the injected animals much as in the con- 

 trols. I was unable to note any well-marked differences in the 

 development and characters of the initial lesion, in those of the pre- 

 auricular and pre-scapular lymphatic infections, or in those of the 

 visceral lesions. 



The favourable influence which serum appears to exercise on some 

 subjects is exclusively due to the animal's individual power of resist- 

 ance, and to the peculiar way in which glanders often develops in 

 guinea-pigs. This is well shown by the fact that progress is slow 

 and development localised just as frequently among control animals as 

 among animals subjected to treatment.
