thin, have a rise of temperature, and finally die. Often fistulous 

 tracts extend under the horny layer as well as in the softer tissues 

 of the feet and legs.

 trimmed away and the fistulous tracts drained, then a disinfectant 

 applied to destroy the germs. An effective remedy for cattle is 

 pure pine tar. The latter may be kept in contact with the dis- 

 eased areas by a bandage passed between the claws, wound 

 around the pastern, and tied.

cable to man. When the lymph glands just beneath the skin 

 are the seat of infection, the term "farcy " is used to designate the 

 disease. It is more likely to attack animals in a rundown con-

 and in mules it is usually fatal. Depending upon the manner of 

 exposure and the virulence of the particular strain of Bacillus 

 mallei, the incubation period varies from one to two weeks.
