SLEEPING SICKNESS.

A NEW FLY DISCOVERED. Much interest is evinced in the recent accumulation of evidence leading to the belief that the scourge of sleeping sickness, which has been the cause of such excessive mortality in the Congo, Uganda, and other parts of Africa, is conveyed by a fly other than that which has hitherto been generally regarded as the sole carrier of infection. The latest evidence on this point comes from North-Eastern Rhodesia, particularly from the valley of the Luangwa, a tributary running northeast from the Zambesi, where a number of eases of sleeping sickness have occurred, both among whites and natives. In this district no Glossina palpalis (the fly heretofore supposed to be the source of infection) have up to the present been discoverable, ' the nearest region in which the fly lives 'being some four hundred miles to the north-west. The newly suspected fly is another species of tsetse fly known as Glossina morsitans, which is to be found much further south than the palpalis and in regions where the latter ia unknown. The Government of Rhodesia, is conferring with the sleeping sickness authorities with a view to the de- , spateh of a new commission of exj perts from Great Britain,
