may be recommended. Any anti-mosquito campaign in this country 

 should be controlled by a committee of experts ; any system leaving 

 the administrative work to local councils directed by leaflets from the 

 Local Government Board is strongly deprecated, as it is considered 

 that this would lead to wastage and unnecessary expense together 

 with weakness on the executive side.

In the middle of the summer of 1917 an outbreak of sand -fly fever 

 occurred in a squadron of yeomanry in mid-Egypt, 86"4 per cent, 

 being infected. The first case was discovered on the 37th day of 

 occupation, being followed by 3 or 4 fresh cases daily for a week, with 

 an average of daily in the second week. The camp was then moved to 

 fresh ground about 1| miles distant, and although it was impossible 

 to avoid carrying the infection, better conditions followed. For 

 military reasons it was desirable to maintain occupation of the first 

 position, and after taking additional preventive measures a guard 

 drawn from another unit was placed in it. Within four days the men 

 showed symptoms of infection and all of them developed the fever. 

 Preventive measures were adopted consisting of cresol spraying, and 

 the use of parafiin o\\ on breeding-places. Every individual had a 

 mosquito net, but this was of little use o'^dng to the small size of the 

 midges. Examples of Phlebohmus were found on walls and in rubble^ 

 and required moisture for their breeding-places,

In January in Macedonia, both in 1917 and 1918, Anopheline larvae 

 were found, but no pupae ; in 1918 very few Anopheline larvae were 

 found in the traps, and none earlier than the middle of May. In 1917 

 it was considered that primary infections began about 1'2\\\ June, 

 which the observations as regards larvae will undoubtedly confirm for 

 1918. The only mosquitos in the earlier months are hibernating and 

 inactive, cases occurring at this period being therefore due to relapses. 

 With the increase of temperature in the summer months cases of 

 malignant malaria occur, which are rare in the winter, the maximum 

 intensity being reached about October or November, from which 

 time it gradually declines, until from March to June such cases are 

 seldom seen. The question has arisen whether A. faleslinensis 

 {.super pictus) carries the siibtertian parasite entirely or better than 

 does A. mactdipennis, as it is more prevalent during August and 

 September when subtertian malaria is most in evidence.
