all proposals in connection with the scientific objects of the 

 Association and report as to their feasibility. The members of 

 this board are appointed for one year, but are eligible for 

 re-election, and they have power to add to their number. The 

 present members are the Director-General Indian Medical 

 Service, the Sanitary Commissioner with the Government of 

 India, the Director of the Central Research Institute at Kasauli, 

 the officer in charge of the Central Malarial Bureau, and the 

 Assistant Director-General Indian Medical Service (Sanitary), 

 and Sir Ronald Ross has been elected an honorary consulting 

 member of the board. 



The scientific objects of the Association are carried out with 

 the aid of "Working Committees," appointed by and acting 

 under the direction of the Scientific Advisory Board — an 

 arrangement which ensures proper correlation of research and 

 prevents overlapping. 



Under the auspices of this Fund, exhaustive inquiries into 

 various problems connected with Kala Azar, Yellow Fever, 

 Plague, Relapsing Fever, Cholera, and Dysentery have been con- 

 ducted by specially selected officers, and several interesting and 

 important discoveries have been made. 



Kala Azar. — The researches into this disease have been 

 carried out under the direction of a Working Committee con- 

 sisting of Surgeon-Gen. Bannerman, Lieut.-Col. Donovan, 

 Major Christophers, and Dr. Bentley, the chief points under 

 consideration being the possible antagonism between Oriental 

 Sore and Kala Azar, and the question of the carrier and 

 reservoir of the parasite of that disease. The actual investiga- 

 tions have been entrusted to Captains Patton and Mackie and 

 Dr. Korke, the division of labour being as follows : Captain 

 Mackie has conducted an epidemiological inquiry into the 

 distribution and prevalence of Kala Azar in Assam, where the 

 conditions for the spread of the disease appear to be peculiarly 

 favourable. Captain Patton and Dr. Korke have worked in 

 Madras, the former devoting himself chiefly to laboratory 

 experiments, whilst Dr. Korke undertook the investigation of 

 the disease in the endemic area at Royapuram. Patton's results 

 are well known. He has undoubtedly proved that under certain 

 definite conditions the parasite of Kala Azar undergoes its full 

 cycle of development in the body of the bug : he has not, how- 

 ever, succeeded in transmitting the disease from one animal to
