The insects were caught in the bedding or on the persons of patients 

 suft'ering from kala-azar ; leeches were allowed to feed on patients 

 whose blood contained Leislimania dotiovani and were examined from 

 1 to 2 months later. In no case was the presence of the parasite detected 

 in insect or leech which had been allowed to feed on an infected patient, 

 nor were the insects capable of transmitting the disease to monkeys. 

 Nevertheless, the author is of the opinion that further investigation 

 on the relation of sand-flies to the disease would be valuable.

The inquiry into the causes of diarrhoea and dysentery in Poona, 

 begun in April 1912, had for its object the study of the epidemiological, 

 clinical and bacteriological aspects of the disease. After giving a 

 survey of the physical characters, climate, population, sanitation and 

 water supply of the town, the relation between flies and diarrhoea in 

 1912, is discussed. To estimate the number of flies and their distri- 

 bution, collections were made at 30 stations in 1912 and at two in 1913. 

 In 1912, the increase in the number of flies from 29th May till 10th July, 

 coincided with increasing numbers of cases of diarrhoea. From 10th 

 to 31st July, there was a decrease in both, followed by a rise in the 

 number of flies to a maximum on 21st August. Two weeks later the 

 flies had disappeared, while the decrease in diarrhoea was less rapid. 

 Three distinct epidemics occurred after the disappearance of the flies. 

 During August, when flies were most numerous, cases of diarrhoea 

 diminished, and two weeks later, when the flies had disappeared, the 

 number of cases again increased. In May 1913, flies and cases of 

 diarrhoea again increased together. A check in the increase of flies 

 on 4th June, was followed, in the next week, by a temporary diminution 

 in cases of diarrhoea. From 18th June onwards the flies diminished, 

 but the disease continued to increase. In 1912, cases were most 

 numerous in the first week in July, while flies were most plentiful six 

 weeks later ; in 1913, flies were most numerous seven weeks before 

 the cases of diarrhoea had reached a maximum. The evidence, thus, 

 does not support the view that flies were in either year the main cause 

 of the epidemic, while the incidence of the disease in the different 

 regiments does not support the fly theory. Admitting that flies may 

 distribute an infective diarrhoea, the evidence that they convey 

 infection to such an extent as to produce the annual epidemic, is 

 insufficient.

Hitherto the only Mallophagan found on the domestic goat has been 

 Trichodectes climax, but on individuals of the merino goat, in California, 

 another and larger species occurs, described in this paper as Trichodectes 

 Jiermsi, sp. n.
