oculation with the serum from the ulcers does not seem to pro- 

 duce the disease. The cause of it is not really known. It is be- 

 lieved to arise from filth. It seems to occur in horses which have 

 not been kept clean and whose harnesses have never been cleaned. 

 The harness rubs against the skin until the surface is raw and an 

 ulcer forms. If the ulcer heals it will eventually return. This 

 condition interferes with the welfare of the animal and he runs 

 down in flesh, getting thin and worthless. In India it is con- 

 sidered a hereditary disease and animals so afifected are con- 

 demned for breeding purposes. The raw surfaces of these ulcers 

 itch a great deal and the itching seems to be mainly around the 

 outside of the ulcer, which is slightly raised. Two or three of 

 these ulcers may start in the same region and by spreading they 

 will become confluent. 



Treatment. — The hygiene is considered important. See that 

 everything is cleaned up and prevent the harness from rubbing 

 the sores. The horse should have a liberal diet and be fed on 

 o-ood nutritious food. Prevent the horse from scratching or bit- 

 ing the raw surfaces if possible. If called early extirpate the 

 inflammatory area if it is not too large. In addition to this give 

 rational treatment. The sores of bursatti are similar to the so- 

 called summer sores although there is a distinction. Neither will 

 endure winter. 



The following is a summer sore lotion which seems to be 



effectual in some cases : 



Spts. Vini Eecti drams xiss

Euealvptol M ij

^ Sig^ — Apply to sore 3 times daily with soft 

 brush or swab. 



To prepare dissolve the eucalyptol in the alcohol ; dissolve the 

 caramel in Ho O, then add the acetic acid and phenol and shake.
