In the history of the Nile there was a void : its
Sources were a mystery. The Ancients devoted much
attention to this problem ; hut in vain. The Emperor
Nero sent an expedition under the command of two
centurions, as described by Seneca. Even Roman
energy failed to break the spell that guarded these
secret fountains. The expedition sent by Mehemet
Ali Pasha, the celebrated Viceroy of Egypt, closed a
long term of unsuccessful search.
The work has now been accomplished. Three
English parties, and only three, have at various periods
started upon this obscure mission: each has gained
its end.
