42 DISCOVERY OF THE PARASITE OF MALARIA 



hospital, and in tlie numerous little houses of the 

 native soldiers "which constituted the barracks, or 

 ' lines,' as they were called. I found, first, the insects 

 with which I was familiar during my previous studies 

 here in 1895, namely, {a) several species of brindled 

 mosquito, and (b) two species of grey mosquito. But 

 at the same time T was astonished at observing that the 

 whole place was overrun by swarms of (r) a small and 

 delicate variety of mosquito which were at once 

 observed to rest with the body-axis at an angle to 

 the wall, and which had spotted wings. In fjict they 

 were evidently of the same genus (though not of the 

 same species) as the mosquito which had been previously 

 found in the Sigur Ghat — a genus, or perhaps family, 

 quite distinct from those of the grey and brindled 

 mosquitos with which I had hitherto been working. 



" In the spotted-winged mosquito which I now found 

 at Secunderabad I noticed at once the general difference 

 of shape, the peculiar attitude of the insects when at 

 rest, the marks on the wings, and the appearance of 

 the eggs (as seen within the body of the female when 

 dissected) ; but the larva3 could not be studied until 

 later. The adults were very delicate, pale brown 

 creatures, which by common consent seemed scarcely 

 to bite man, though they were numerous enough to 

 have caused much irritation had they done so. They 

 swarmed in my own quarters, but seldom bit me. 

 They abounded also in the houses of the other officers 

 of the regiment who, with their families, had remained 

 quite free from malarial fever. Consequently I was 

 not disposed to think that they had anything to do 

 with the disease. On the other hand, the grey mos- 

 quitos swarmed in the barracks, but were much less 

 numerous in the officers' quarters (situated some
