THE LATE MR. ROBERT JAMIESON.

We regret to announce the death of this gentle-
man at his house in Gloucester-square on the morn-
ing of the sth inst. As an enlightened philanthro-
pist he had for many years devoted much time and
wealth in endeavours to improve, civilise, and raise
the native races of Africa from the barbarism in
which they have been so long involved. This he
sought to accomplish by establishing commercial
relations with the country by means of the rivers
that flow from the interior into the Atlantic. In
this view, in 1839, ha built and fitted out at Liver-
' pool, with much care and expense, the Ethiope
steamship, appointing to her command the late Capt.
Beaeroft, to whom he gave minute and ably-written
instructions for his guidance in exploring and trad-
ing voyages. In compliance with these instructions
the.,Ethiope made numerous attempts at discovery
in the great rivers and their tributaries, ascending
to higher points in some instances than had ever
previously been reached by Europeans. Narratives
of these voyages were published by Mr. Jamieson,
and others are given in the journals of the Royal
Geographical Society. The success of his well
concerted plans was marred by the well meant, but
ill judged, interference of our Government, and
when the unfortunate "Niger expedition" was
projected Mr. Jamieson, being convinced of the
unsoundness of the scheme, published two Appeals
to the Government and People of Great Britain
against the project. When the disastrous con-
sequence followed which he had foreseen the
orders that he had given to the Ethiope en-
abled Capt. Beacroft to rescue from impending
destruction her Majesty's ship Albert, one of the
vessels employed in the expedition, while by carry-
ing her down to Fernando Po he saved those on
board from perishing by fever. In 1859 Mr.
Jamieson published a tract, entitled " Commerce
with Atrica," pointing out the benefits that might
be obtained by establishing a short inlani commu-
nication between Cross River and the Niger. to
avoid the swamps of the Delta; but his advancing
years and failing health precluded further active
exertions. In 1840 the Institute d'Afrique of France
proposed to Mr. Jamieson to become one of their
vice-presidents ; but this honour he declined. He
was eminently successful as a merchant, and had
extensive transactions with South America, Brazil,
India, and China. In his private relations he was
most amiable. Modest and unassuming, his bene-
volence was at once extensive and unostentatious;
and ho was ever ready to promote, by all the means
in his power, the interests of those deserving and
industrious persons with whom he was acquainted.
