FEAR OP HYDROCEPHALUS.

the northeast of the mound becomes Battle Frere’s Lu*. 
laba, and it flows into one of the lakes proper, Komolondo, 
of the central line of drainage; Webb’s Lualaba, the second 
fountain rising on the northwest, becomes (Sir Paraffin) 
Young’s Lualaba, which passing through Lake Lincoln 
and becoming Loeki or Lomaiui, and joining the central 
line too, goes north to Egypt. The third fountain on the 
southwest, Palmerstone’s, becomes the Liambia or Upper 
Zambesi, while the fourth, Oswell’s fountain, becomes the 
Kafue and falls into Sambesi in Inner Ethiopia. 
More time has been spent iu exploration then 1 ever an- 
ticipated. My bare expenses never paid for two years ; 
but had 1 left when the money was expended 1 could have

foot I trod ere I got a clear idea of the drainage of the 
great Nile valley. The most intelligent natives and traders 
thought that all the rivers of the upper part of that valley 
flowed into Tanganyika. But the barometers told me that 
to do so the water must flow up hill. The great, rivers and 
the great lakes all make their waters converge into the 
deep trough of the valley, which is a full inch of the baro- 
meter lower than the Upper Tanganyika. It is only a 
sense of duty, which I trust your lordship will approve, 
that makes me remain and, if possible, finish the geogra- 
phical question of mv mission. Alter being thwarted, baf- 
fled, robbed, worried almost to death in following the cen-
