An inclination to heal will be noticed in some 

 of the pustules and sores, especially when energetic 

 treatment is resorted to. 



In the event of suspicious indolent subcutaneous 

 nodules being observed, diagnosis might be accelerated

 and smears from the nodules. However, I have 

 no knowledge of this method of diagnosis having

 effort should be made to reduce the number of 

 wounds to a minimum, so in adopting this as a method 

 of diagnosis there are many points which require very 

 careful consideration before it could be generally 

 recommended.

I. Glanders (farcy), as has been already inferred, 

 is the disease with which epizootic lymphangitis is most 

 likely to be confounded, and the latter may be

 disease tends to become generalized, 

 (ii) Almost invariable absence of fever, 

 (iii) Unimpaired appetite, 



(iv) Characteristic appearance of the ulcers and 

 sores, which have an inclination to granulate 

 and with energetic treatment to heal, and,
