NOTES. 
(*) This is the seventh chapter of Book IV. After indicating the geographical positions 
of the two lakes sources of the Nile, it would naturally occur to Ptolemy to give that of the 
more southern snowy mountains. But he does not do so, and only speaks of them incidentally 
in chapter 8 of the same book, where there is no further reference to the Egyptian river.

chaps. 4 and 6 of Book I. 
( 9 ) The defects of this method, and the serious errors committed by Ptolemy in 
recasting and expanding the work of Marinus of Tyre, are excellently exhibited, with his usual 
clearness and shrewdness, by Vivien de Saint-Martin ( Eistoire de la Geographie , 
pp. 200 and 201). On Ptolemy’s geographic system specially valuable are the pages 
devoted to this subject by Bvnbury in his History of Ancient Geography (2nd edition, 
Vol. II, pp. 546-579).
