_Observations on an Historical Account of Discoveries and Travels
in Africa, by the late John Leyden, M.D., by Hugh Murray, Esq.
F.R.S.E._

TO HUGH MURRAY ESQ. F.R.S.E.

Sir,

London, Feb. 1818.

You have certainly rendered to your country a service, in the
publication of "The Travels and Discoveries in Africa, of the late
John Leyden," the perusal of which has been to me a fund of
instruction and entertainment; it is a most valuable work, and such
a one as was wanted by the literary world, inasmuch as the
judicious collection of the matter forms a most valuable epitome of
African knowledge, collecting what was before distributed into many
folios.

I anticipate that the information in this work, communicated to the
public, will soon be circulated, and you will be called upon to
supply a second edition. In the mean time, I take the liberty of
submitting to your perusal a few cursory observations which I have
509 made during the perusal of it, on the accuracy of which you may
assuredly rely. These apply for the most part to Arabian words,
which have been by the moderns, as well as the ancients variously
corrupted and mutilated. Desirous (for the information of those who
really seek after African knowledge) that this book will pass
through many editions. I am, &c.

JAMES GREY JACKSON.

_Cursory Observations_.

"The _Ludaia_, are not inhabitants of _Ludama_, they are a very
numerous and warlike tribe of Arabs, inhabiting the Sahara, of
which there are two or three emigrations or encampments in
different and distant parts of Sahara; the Emperor of Marocco has
some thousands of them in his army, and they are esteemed (next to
the negroes, called Abeed Seedy Bukaree) his best troops. See the
Map of the tracts from Fas and Arguin to Timbuctoo, facing page 1.
