2. Ulcerative lymphangitis. This is a disease 

 which has been differentiated from the other forms of 

 lymphangitis by Nocard, and is due to a bacillus dis- 

 covered by him in 1892, and care should be taken not 

 to confound it with the disease herein described, as has 

 already been done by many writers on the subject. 



As far as 1 can gather from the literature on the 

 subject, it is a disease that has only been recognized in 

 France, although Nocard and Leclainche have a 

 footnote in their book referring to Moore's cases as 

 possibly simulating the disease ; but, judging from 

 Pease's pamphlet on the subject, I am inclined to 

 think that they were none other than epizootic 

 lymphangitis, as the cases did not easily yield to 

 treatment, and experimental inoculations made from 

 them tailed to produce orchitis in guinea-pigs, a point 

 which is said to be characteristic of the ulcerative 

 form of lymphangitis. 



Schwarzkoff, in an article in the American Veterinary 

 Review^ describes some cases occurring amongst the 

 American horses during the campaign in the Philippines 

 under the name of tropical ulcers of the horse, which 

 Nocard and Leclainche also refer to ; the cases were 

 noticed during the rainy season, and may possibly have 

 been nothing more than bursatti, or a vesicular eruption 

 around the coronets, as is often seen amongst horses 

 running at grass during the rainy season in India. 

 According to Nocard and Leclainche, the bacillus of 

 ulcerative lymphangitis is found abundantly in the pus, 

 it is an ordinary saprophyte, and is easily stained by 

 Gram's method. 



In this disease the sores are also said to 

 resemble very much those of farcy, but there is an 

 absence of induration of the lymphatic glands, and 

 the ulcers and sores easily yield to treatment.
