Far more important and generally interesting, how- 

 ever, is the geographical knowledge brought home or 

 rather confirmed to us by Mr Wakefield's ' Routes.' We 

 now know that the block whose apices are Mounts 

 Kilima-njaro and Kenia (alias Doenyo Ebor, Mont Blanc) 

 to be a great upland, bounded on the South by the 

 Panga-ni river in S. lat. 5°, and on the N. West by a 

 lacustrine region in S. lat. 6° ; whilst it may possibly 

 anastomose to the North, as was suggested by my friend 

 Dr Beke, with the Highlands of Harar and of Moslem 

 Abyssinia, lying upon the same meridian. The breadth 

 between X. West and S. East will be included between 

 East long. (G.) 37° and 39°. Assuming, therefore, roughl} r 

 the bounding lines to measure 240 by 120 direct geogra- 

 phical miles — we obtain a superficies of 28,800 square geo- 

 graphical miles, more than a fourth of the area assigned to 

 the British Islands. We can now safely believe, with Dr 

 Krapf and Mr Rebmann, the explorers, that the block is a 

 high volcanic country, separating the watershed of the 

 Nilotic Basin from that of the Indian Ocean ; sending off, 

 like the Highlands of Abyssinia, its own tributary or 

 tributaries to the White river, and corresponding with 

 the Camarones or Theon Ochema in West Africa (X. lat. 

 4°) ; that it is a land of high plains and thickly forested 

 hills, rising to summits capped, not with delomite and 

 quartz, but with glaciers and eternal snows ; and that it 

 abounds in the lakes and swamps, sweet and salt, necessary 

 to feed the inland ' smoke mountains ' or volcanoes, 1 whose
