INSTITUTE AND COLLEGE, PUSA, FOR 1912-13. 83 



At the end of the rains I spent some time in Poona in 

 company with Captain Morison, I.M.S., and inspected the 

 breeding-grounds of Muscid flies which were suspected of 

 a connection with a form of enteritis prevalent at Poona. 

 Experiments on marked flies were carried out to ascertain 

 how far the city trenches were responsible for the very 

 great abundance of flies in the city and cantonments. An 

 assistant was deputed to remain at Poona and assist 

 Captain Morison in the investigation of breeding-places 

 and the other entomological work necessary. An assist- 

 ant was similarly deputed to assist Major Greig, I.M.S., 

 in his investigation of typhoid fever at Puri, and the part 

 played by flies in its transmission. In collaboration with 

 the Medical Officer at Pusa observations are being made on 

 the flies responsible for the cases of myiasis which are 

 somewhat common in the district- 



One assistant attended the malaria class, under Captain 

 Hodgson, I. M.S., at Delhi. A large number of mosquitos 

 and other insects, sent in mainly by Medical Officers, have 

 been identified. I gave a series of lectures with practical 

 instruction on methods of drawing and illustrating. 



In November I had the pleasure of attending the 

 Malaria Conference at Madras and read three papers : — 



" The yellow- fever mosquito." 

 " The breeding-places of Phlebotomus." 

 " Insect psychology and its bearing on methods of 

 control." 



Two papers have been contributed to the first issue of 

 the " Indian Journal of Medical Research " : — 



" The natural host of Phlebotomus minutus." 

 " Insect life-histories and parasitism."
