Formation and General Features of Ruwenzori. 
months of residence in the regions close to the chain during the 
work of the Anglo-German Boundary Commission. Behren’s 
article contains in clear and succinct shape the net result of all 
that was known about Ruwenzori previous to the Italian 
Expedition. 
The following table, in which the names given to the 
mountains by different travellers are placed in order with 
reference to those marked upon the Italian map, illustrates the 
confusion which had 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 nomenclature 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 which 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-off plains of the surrounding country. 
The Duke took for the first base of his calculations the 
meteorological station of Entebbe, whose height was already 
known (3,861 feet). Fort Portal was then connected with 
Entebbe by a series of observations carried out for two whole 
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
