REPORT ON DOURINE. 



arrangements for keeping horses under observation for long- periods, 

 no further head-way could be made with the investigation at that 

 date. 



During the latter half of 1902, a widespread epizootic of the 

 disease came to light, especially in the Punjab and certain districts 

 in the United Provinces bordering on the eastern bank of the river 

 Jamna. 



The following report deals with Dourine as observed respectively 

 in English and Australian thorough-breds and in Arab stallions, 

 which exhibited the disease in Chronic, Latent, and Recent forms. 

 In addition, experiments with regard to the intimate etiology and 

 pathology of the. disease have been carried out in Australian, Country- 

 bred, and New Zealand mares, while in stallions an Arab horse, 

 country-bred tats, and country-bred donkeys have been utilized for 

 the purpose. 



My best thanks are due to 



Colonel J. W. A. Morgan, Inspector-General, Civil Veteri- 

 nary Department, for animals received from Babugarh. 

 Colonel H. Goad, Director-General, Army Remount Depart- 

 ment, for cast mares from Saharanpur, Karnal, and 

 Hapur. 



Major H. T. Pease, Principal, Lahore Veterinary College, for 

 Dourine stallions and for valuable information with 

 regard to the disease under investigation. 

 In the course of this report it is not my intention to deal with 

 the geographical range of this disease, and other details which can 

 be gleaned from books on the subject, but mainly to put on record 

 the course of the malady as observed in equines, etc., of different 

 breeds in this country, and give a short summary of the life history 

 of the trypanosoma so far as our investigations have allowed us to 

 determine in the multiplicity of other researches and routine duties. 

 A detailed account of the trypanosoma will be published separately. 

 I would here mention that on embarking on this enquiry it was 

 hoped that one disease, and one disease only, viz., Dourine, would 

 have been encountered, but on having to write an account of the 

 experiments carried out, one finds it necessary to give details of two 

 other forms of disease, one which complicated the majority of cases
