46* L. Uogers— Special Report on Fever in Binajpur Dist. [SuppU. 



Purnea district, I made enquiries from the district autliorities as to the 

 parts at present affected by the disease, and was informed by the Civil 

 Surgeon, Captain Hayward, I. M.S., that it was to be found in the north 

 of the Kissenganj subdivision. I wrote to the Subdivision al Officer for 

 information some three weeks before I intended to start for the Purnea 

 district, but did not receive any reply until after my return from a 

 fruitless search for the disease, and then was informed that it had died 

 out of the district. During my visit to the area under the kind 

 guidance of Captain Hayward evidence was obtained of the spread of 

 the disease in a northerly direction, for at Aloobaree it had been pre- 

 sent eight years ago, while eight miles further north at Chapra it has 

 disappeared only three years ago. Oq reach insr Thaurganj, 16 miles 

 north-west of the first-named place, search was made for cases in the 

 neighbouring villages which were badly affected by the disease at the 

 time of the enquiry made by Major Harold Brown^ in 1898, but here 

 we were informed that it had disappeared a year ago, and two persons 

 who had suffered Prom the disease were shown me, one of which had 

 been free from fever for a year and appeared to be nearly completely 

 recovered from its effects, while the other had had no fever for six 

 months, and but was still thin and his spleen reached nearly to the 

 navel. No cases still suffering from fever could be found, so no spleen 

 punctures could be performed with any hope of finding the new para- 

 site-like bodies. 



On the other hand, thanks to the kindness of Dr. Dodds Price of 

 the Nowgong district of Assam (who helped me so materially in my 

 enquiry into the nature of Kala-azar in 1896-97) in very kindly send- 

 ing me slides made from blood obtained by spleen puncture in seven 

 cases of Kala-azar, I was able to search for the new parasites in these 

 cases. The results are shown in the following table : one slide was 

 spoilt in trying a new fixing agent : —

Note. — This observation has since been confirmed in two further series of 

 slides from Kala-azar oases.
