African Exploration. — The Royal Geographical Society has 

 decided to send a new exploring expedition to Africa under the 

 command of Mr. Joseph Thomson. After organizing his com- 

 pany at Zanzibar, Mr. Thomson will proceed from Mombas on 

 the East African coast to Mount Kilim mdjaro, and after ascend- 

 ing this celebrated peak, he hopes to advance through an entirely 

 unknown region to the shores of the Victoria Nyanza, returning 

 to the coast by a more northerly route so as to visit, if practica- 

 ble, Lake Baringo and Mount Kenia. 



Lieutenant Giraud, a young French naval officer, has sailed from 

 Marseilles for Zanzibar. He intends to go either to Lake Tan- 

 ganyika, or more probably by the north shore of Lake Nyassa, 

 to the Chambeze River. He will follow this stream to its outlet 



then hopes to de, id th I.i > i'-< igo to the sea. & 



The French Government has decided against the scheme of M. 

 Roudaire of flooding a portion of the Sahara, considering that the 

 cost will exceed the advantages to be gained. 



Professor Guido Cora in' an address before the- Italian Geo- 

 graphical Society, describes the Desert of Sahara as an immense 

 tract of country, with a mean elevation of from 1300 to 1650 feet 

 above the level of the sea, in which sand does not occupy more 

 than one- fifth of the entire area, and where 1 irgc chains of moun- 

 tains are found v of from 6^0 feet to 8200 feet.
