Formation' and General Features of the 
Ruwenzori Range. 
Ruwenzori and the “ Albertine Depression ”—Relation to the Nile Basin— 
Nomenclature — H.R.H.’s Map — The Six Groups of Snow Peaks — The 
Watershed—The Distribution of the Valleys—What preceding Explorers 
saw of the Mountains—Confusion of Names and Topography—-Altimetric 
Measurements—The Geology of the Range—The Glaciers—Flora and Fauna.

the two chief groups: of peaks

of the expedition both quicker and easier.
