months of residence in the regions close to the cliain during the 

 work of the Anglo-German Boundary Commission. Behren's 

 article contains in clear and succinct shape the net result of all 

 that Avas known ahout Ruwenzori previous to the Italian 

 Expedition. 



The following table, in wliich the names given to the 

 mountains by different travellers are placed in order Avith 

 reference to those marked upon the Italian map, illustrates the 

 confusion whicli liad arisen from mistaken identification of peaks 

 from various points of observation. This table will make it 

 easier to compare the accounts of all the previous journeys. It 

 will also show that the only way to put order and clearness 

 into the nomeuclatm-e was to give up the old names and start 

 afresh with a different plan. 



As regards the altitude of the highest point as determined 

 by the Duke at 16,815 feet, it would be idle now to gather 

 together the opinions of preceding explorers Avhich were not 

 based upon any instrumental observation ; all the more so that 

 only one of them, Stuhlmann, really had a near sight of the 

 highest peaks, or at least of Alexandra Peak. The others 

 all judged of the height of the peaks around the head of the 

 Mobuku Valley, and never even saw the highest ones, or 

 only from the far-oft' plains of the surrounding country. 



The Duke took for the first base of his calculations the 

 meteorological station of Entebbe, whose heiglit was already 

 known (3,861 feet). Fort Portal was then connected with 

 Entebbe by a series of observations caiiied out for two A\-liole 

 months at the two stations, and giving as a result for Fort Portal 

 an altitude of 1,165 feet above Entebbe, or 5,026 feet above the 

 sea-level. Finally, Bujongolo was connected with Fort Portal 

 by barometrical observations taken during a period of about a
