If the Victoria Lake were large, then it and the Albert would probably be the Lakes which Ptolemy meant, and it would be pleasant to call them Ptolemy's sources, rediscovered by the toil and enterprise of our countrymen Speke, Grant, and Baker--but unfortunately Ptolemy has inserted the small Lake "Coloe," nearly where the Victoria Lake stands, and one cannot say where his two Lakes are.

Of Lakes Victoria, Bangweolo, Moero, Kamolondo--Lake Lincoln and Lake Albert, which two did he mean?
The science in his time was in a state of decadence.

Were two Lakes not the relics of a greater number previously known?
What says the most ancient map known of Sethos II.'s time?
_16th April, 1872._--Went over to visit Sultan bin Ali near Tabora--country open, plains sloping very gently down from low rounded granite hills covered with trees.

Rounded masses of the light grey granite crop out all over them, but many are hidden by the trees: Tabora slopes down from some of the same hills that overlook Kwihara, where I live.

At the bottom of the slope swampy land lies, and during the Masika it is flooded and runs westwards.
