GEOGRAPHY AND TRAVELS.! 
Unknown Arrica.—M. H. Duveyrier has recently read a 
learned paper before the Paris Geographical Society in which he 
divides the pa aR portions of Africa into six great regions. 
These regions are: 1. The balani and the Libyan Desert, meas- 
uring 5,750,000 aiet kilometres, and notwithstanding its deso- 
late aspect containing in s ancient populations and rich oases 
much of great interest. In the west the country between the 
Joliba and the coast of Guised covering the surface of 1,200,000 
square kilometres. 3. In the center north of the equator the 
upper courses and the sources of the Benué and the Shari com- 
posing an area of 800,000 square kilometres in which to seek to 
complete our knowledge of the basins of the Nile and the Shari, 
and to discover the sources of the latter and those of the Benue. 
4. In the southern equatorial zone adjacent to the preceding and 
embracing the head waters of the Nile, the sources of the Ogowé 
and the basin of the Congo, extending over 2,000,000 square kilo- 
metres, some of the greatest problems of African geography re- 
main to be decided. 5. In the south the basin of the Cunene 
and the districts about Angola and Benguela. 6. Finally, in the 
east, the region which forms a triangle culminating in Cape Garda- 
fui whose interior is totally unexplored, and presents subjects of 
investigation not only geographical, but also historical of the high- 
est interest. 
Adding together the areas se these six great lacunz, we find 
they amount to upwards of 11,000,000 square kilometres—more 
than one-third of the nates continent, But there is no reason 
to be discouraged at this large figure. Since the beginning of 
the present century the exploration of Africa has pro- 
gressed at a mean rate of 234,285 square rear es per year, — 
and if it goes on at this rate, the whole of the African inter- 
ior ought to be known in less than D years. But this 
calculation takes no account of the geometric progression of the 
figure of these discoveries which now produce in one year more a 
than in the first twenty years of the century. 
AFRICAN Exprtoration.—Dr. Gerhard Rohlfs arrived at Tripo- 
lis on the 24th of October last. He expects to proceed early in- 
December to Kufrah and thence to Wadai. He will then en- 
deavor to trace the rivers Shari and Benué to their sources, and 
to explore the region intervening between them and the rivers
