148 PAEASITIC SKIN DISEASES. 



MICROSCOPICAL EXAMINATION OF KUNKUR.— When a 

 portion was examined in water, it appeared to be quite amorphous ; 

 with acetic acid it looked somewhat like a hardened cell-con- 

 gIom.eration, but the appearances were not sufficiently marked to 

 justify a statement. The masses may be, and probably are, 

 concretions of pus and epidermic cells formed by heat and dryness. 

 The nodules, like those of actinomycosis, probably consist of 

 fibrous tissue. Mycelium and spores have been found in the 

 lesions and cultures of the fungus grown on Sabouraud's medium. 



PREVENTIVE MEASURES.— Special care should be devoted to 

 obtaining as pure a supply of water as possible. All scratches, 

 abrasions and cuts should be treated antiseptically (p. 67), as, for 

 instance, with sulphur and oil mixture (p. 146). 



Flies, during the hot weather, being a source of extreme annoy- 

 ance to horses, as well as possible carriers of the disease, should 

 be excluded, as much as possible, from the stable by screens, and 

 by keeping the building dark ; though without, in any way, 

 impeding the due circulation of air through it. The stalls should 

 be kept scrupulously clean ; for the presence of dung and other 

 dirt attracts flies. 



During the hot weather in India, the horse should have a plenti- 

 ful supply of green fodder. His grain should consist of, at least, a 

 third of bran (by weight) ; he should get steady and regular 

 exercise, and be thoroughly well groomed at least twice a day. 



I am strongly opposed to the practice of frequently washing 

 horses ; but cannot say that it induces bursatee. 



TREATMENT. — The theory as to the parasitic origin of 

 bursatee indicates, and experience proves, that the proper treat- 

 ment is to destroy the surface of the sore, so as to produce a 

 healthy wound ; and then carefully protect the part from the action 

 of air and moisture ; from friction or injury of any kind ; and 

 from irritation due to dirt, flies, etc., lodging on it. 



Use, in the first instance, undiluted carbolic acid freely to the 

 ulcer, so as to destroy its surface ; and then keep on it a solution 

 of 2^ parts of camphor in 1 part of carbolic acid. 



When the wound assumes a healthy look, substitute the carbolic 

 acid and camphor solution, given on p. 69. 



As an alternative treatment, in case the foregoing does not .effect 

 a speedy cure, the application of turpentine is advised ; a 

 saturated solution of iodoform in eucalyptus oil (say, a drachm 

 to the ounce); eucalyptus oil; powdered iodoform or tannofornr; 

 or burnt alum. 



It has been suggested that nothing should be done to a bursatee
