CO N ST R U C T IO N
OF THE
GEOGRAPHY OF MR. HORNEMAN’S EXPEDITION
IN AFRICA.
CHAPTER I.
I n the discussion of the construction of this Geography, I shall
Confine myself, as much as possible, to general statements ; reserving
more particular details to a future time, when more materials
may arrive : for it is to be observed that although Mr. Horneman
has transmitted much valuable matter, yet that it is not altogether
of the kind required for the construction of mathematical geography.
Fortunately, however, the observations of Mr. Browne and others,
enable me to derive more advantage from those of Mr, Horneman,
than could have been obtained from them, alone.
The„geographical positions of Cairo, Alexandria, and Fezzan,
havé undergone some small change in the present maps,* in consequence
of récent, and it may be supposed, more accurate information.
Cairo is placed 3 min. and Alexandria 13, more, to the west,
in consequence of the French observations : and Mourzouk, the
Th e Reader, is referred,to the Map of Mr. Horneman’s Route, page 29, and to
the General Map of Africa, opposite Chapter I I I .
