FRANCE,

BOURSE, July 10.—The flatness and inactivity
habitual to • the commencement of the week have
again predominated in all the markets to-day.
Offers to sell have been the ruling feature of transac-
tions, and the result is a modification in the rates
of nearly all the principal Securities. Threes, for
the Account, have receded to 67f. 5c., and Mobilier
shares to 653 f. 75c. Italian Five per Cents. remain
without change at 64f. 75c. The market has im-
proved towards the close, and left off as follows :--

The Last Nile Discovery.

....-..,---.--....

TO TIIE EDITOR OF THE SUN.

Sir,—Having during the last few days met with
many persons who have said that they are unable to
form a clear conception of the relations of the two
vast equatorial African lakes--the Victoria of Speke
and the Albert of Baker—to each other and to the
Nile, I venture to offer the following brief explana-
tion.

Let the inquirer consult the map contained in
Speke's book, and he will see at a glance how the
discovery of Baker has substantially confirmed the
views of his distinguished precursor.
Speke places the Luta Nzig6 (now the Albert) on
his map as a great sheet of water of which he had
heard, and into which the Nile, from the point where
he was obliged to quit it, descended by rapids, and
then reissued a little to the north to flow to Gondo-
koro. So strongly did he believe, from the descrip-
tion of the natives, that such would be found to be
the case that he incited his friend Baker to endea-
vour to ascertain the facts.

Now, in every essential point the researches of
Baker have confirmed the accuracy of the views of
Speke as regards the Luta Nzige ; for the Nile,
leaving its first great and lofty reservoir, the Vic-
toria, at a height of 3,740 feet above the sea, is
found to descend 1.670 feet into the deep rock-
.

Nyanza, which
basin of the Luta Nzige, or Albert
is placed by Baker at the elevation of 2,070 feet.
Thence the stream flows downwards and northwards
to Gondokoro, from which place to Khartum,
where it is joined by the Blue or Abyssinian Nile,
it becomes, as is now well known, a perfectly navi-
gable stream.
The representations of ancient geographers, as
seen on old maps, of two streams issuing from two
separate and unconnected lakes, these streams unit-
ing further north to form the Nile, is proved to be
erroneous ; since we now know that, whether in the
form of lake or river, the White Nile consists of one
continuous system, the waters of which descend in
the first instance from a higher into a lower lake,
and thence into the main stream, which in its course
to Gondokoro and Khartum is fed by many other
affluents. In short, the water system by which
these lakes of the Nile are first connected and then
feed the main stream, is analogous to the connection
between the North American lakes and the issue of
their waters into the St. Lawrence.—l remain, Sir,
your obedient servant,

RODERICK I. MURCHISON.

AN INFAMOUS DOCTRINE!--From Mr. John
Stuart Mill's work on " Liberty," p. 92 :—" I believe that
other ethics than any which which can bo evolved from
exclusively Christian sources must exist side by side with
Christian ethics to produce the moral regeneration of the
world,"

THE PARLIAMENTARY RETURN of the INSURANCE
DUTY paid in 1864 has just been published, aid is
the first return embodying the differential rates on stock
(Is. 6d. per cent.), and on Buildings and Furniture (3s. per
cent.), the reduction of the duty on stock having com-
menced at Midsummer, 1864. For the purpose of compar-
ing the business of each company with that of 1863, we
have been obliged to make up an account for 1864, as
though the duty had remained unaltered. We thus get a
measure of the progress of each company, and the result is
as follows:--
