and gritty. Around the central portion was a zone of leucocytes 

 {polynuclear cells predominating), a number of which contained 

 spores. The nodule itself appeared to be composed of a dense 

 network of mycelium, intermingled with disintegrating leucocytes 

 and spherical bodies, probably spores. Many filaments ended in 

 club-shaped enlargements, but these were not regularly pointed 

 outward in tufts as in actinomyces. The calcification seemed to 

 be mainly resident in the mycelial network. The solution of the 

 animal tissues in a 10 per cent, cold solution of caustic potash for 

 twelve hours rendered the fungous growth very evident. 



Treatment. Accepting the disease as due exclusively to the 

 local propagation of the cryptogam, one is unable to explain its 

 spontaneous recovery on the advent of cold weather and its re- 

 currence in the same seat with the onset of the hot damp weather 

 of the succeeding season. Equally difficult is it to explain why 

 in the more temperate regions like New York the disease will per- 

 sist for years in one horse in a stable and respect the second horse 

 of the same team, though dressed daily with the same brush and 

 rubber, and pestered by the same flies that suck the liquids from 

 the kunkurs. Manifestly, as in many cases of favus and ring- 

 worm, the one animal acquires a constitutional susceptibility to 

 which the other is a stranger. It may be also that the spores 

 hibernate in the system, to wake to new life the following sum- 

 mer. A purely local treatment may therefore be insufficient, yet 

 such treatment of the skin, where the diseased process is so active, 

 cannot be looked on as superfluous nor irrational. 



In mild cases at Ithaca the scraping out of the nodule and the 

 daily application of iodoform has secured a speedy healing. In 

 more advanced and inveterate cases the frequent douching with 

 cold water from a hose or watering pan and the application of 

 tincture of iodine have hastened healing. 



In India the most varied opinions have been advanced. ' ' Max ' ' 

 alleges that no bursatti sore will resist treatment if protected from 

 the flies. Steel would prevent infection by covering all sores by 

 antiseptic dre.ssings, especially carbolic acid, and the infected 

 sores should be dressed with carbolic, salicylic or sulphurous acid. 

 Others have sought to slough out the diseased mass by the use of 

 white arsenic in powder, or by cauterization with the actual 

 cautery, caustic potash, silver nitrate, blue stone and other agents.
