AFRICAN DISCOVERY.

The following letter has just been received at the
Royal Geographical Society, and is of importance, as
recording one of the greatest geographical explorations
of the age :

" St. Paul de Loando, May 15, 1854.
"My Lord,—l take the liberty of transmitting to you
herewith, as President of the Royal Geographical Society,
an extract of a letter which has recently been received by
a merchant in this city from his correspondent at Cassange,
a district in the interior of this province, within the juris-
diction of the Portuguese Crown, announcing the arrival
at that place of Mr. Livingston from the Cape of Good
Hope, probably the same gentleman who, in company with
Mr. Oswell, reached the shores of Lake N'gami in July,
1849.

" Although I was not aware that any attempt had re-
cently been made to explore the interior of this part of
Africa, still I have no reason to doubt the accuracy of the
information contained in the accompanying extract.
"In the event of Mr. Livingston having set out from
the Cape Colony for the purpose mentioned, your Lordship
will doubtless be acquainted with the fact, and, should
such be the case, I think full reliance may be placed on the
information of his arrival at Cassange.
"That place is said, upon the best authority I can find
here, to bs situated on the confines of the Portuguese terri-
tory in Angola, at about 180 miles from this Lity, in an
easterly direction, and it is the seat of an important track
between the Portuguese and the natives of the interior.
" Should any further information reach me respecting
Mr. Livingston's movements I shall not fail to communi
cate it to your lordship, and, trusting that you will pardot
this intrusion, I have the honour to be, my lord, your lord
ship's obedient humble servant,

" EMI. GABRIEL.
"To the Right Ron. the Earl of Ellesmere, President
of the Royal Geographical Society."
The following is the translated extract of a letter from

his employer at St. Paul de Loando, under date the

versF.i, with the most insignificant resources, the whole of
the interior from the Cape of Good Hope, whence
.he set
out on his journey. What he wishes to acquire is, not
very great and i
money, but a good name. He is a missionary, and appears
to be a man of much erudition, zealously applying himself
to the attainment of a knowledge of the geography of the
Country. In the maps of the interior of Africa he will
make
Dr. Livingston's explorations, from lat. 18 to lat. 14,
together with his sound astronomical observations, the
best taken since those by Mr. Galton, were laid before
the Royal Geographical Society at its last meeting. The
present notice is, therefore, a proof of the successful
issue of this great undertaking.

MEXICAN DOLLARS.—The dollars brought by the last
West India packet were disposed of yesterday at 62d.
for the China market. This is an advance of id. per ox.
on the price realised for those by the preceding Mexican
packet, although during their scarcity at the latter part
of July parcels were sold at still higher rates.
