but the immediate establishment of cultivated plants is imperative 

 or the clearings will become covered with bush very favourable to 

 Glossina ; this has actually occurred in one case. 



Among 5,000 individuals examined in the Dume district Dr. 

 Schachtmeyer found 14 per cent, to be infected, and the actual 

 percentage is probably higher owing to the authorities not having 

 secured the full confidence of the natives. 



It had been previously stated that in New Kamerun the high sickness 

 figures had no relation to the few Glossina present. The author did 

 not observe such a discrepancy. It is true that on the Carnot-Kumbe 

 road no G.palpalis is found close to the villages, whilst from per cent, 

 to 52 per cent, of the population is infected ; but at a distance of one 

 day's march east and west of the road there are rivers heavily infested 

 with this fly, and there is a constant inter-communication between the 

 natives. 



G. fusca is also fairly frequently met with. At Kumbe Dr. Fischer 

 captured 1,011 specimens of G. fusca in 4 weeks and fed them on a 

 species of Cercopithecus. Though none of these monkeys contracted 

 sleeping sickness, the author does not doubt that G. fusca is capable of 

 transmitting it.

Numerous references are given to the literature on ocular myiasis. 

 Of the 40-50 cases recorded in detail the majority appear to be due to 

 larvae of Rhinoestrus purpureus or allied flies, even where those of 

 Oestrus avis have been thought to be involved. The " Thun'ni " 

 ocular myiasis described by the brothers Sergent from Algeria and the 

 Sahara and held by them to be due to 0. ovis, is considered to be better 

 ascribed to Rhinoestrus in view of the biology and distribution of these 

 flies ; this affection has only been observed in the distributional area 

 of R. purpureus {nasalis). 



A record is given of what the author believes to be the only fully 

 authenticated case of human ocular myiasis from France. It is 

 believed to have been due to R. purpureus,
