ZITRACT OF A LETTER FROM NICHOLAS GRAY. U.S., Surveyor to the
Hon. T. 0. LARKIN. Dated Hamilton, June I 1 th, 1852.
" With this you will receive a small box of specimens of gold-
bearing quartz. The specimens here sent are not selected specimens,
because I wished to inform you corrretly, or within the truth, so as
tO tear future examination. I saw much richer specimens.
" This was dug out of a hole about 1% miles from Pocenix Mill
known as the Bloomingdale ledge or lead.
It is stated by Mr. Larkin's agent in this country that the box was
sent unopened from San Francisco to London, and assayed by John-
son and Matthey, and that in the specimens no gold was visible to
the naked eye. Th. report of Messrs. Johnson and Matthey is as
follows :
" Assay-office, 79, Hatton-garden, London,
August 25, 1852.
"The box of gold quartz had half of each piece taken off, and the
whole crushed.together very One, giving grains of gold, which would
lot pass through the sieve, equal to Soz. 10 dwt. of fine gold to the
ion of 20 cwt. The line powder produced, by assay, gold equal to
11oz. 10 dwts. of line gold to the ton of 20 cwt.

20 oat the present price of fine gold—viz., 84s. 7Ud. per oz.—
glees a value of about 841. to the ton of 20 cwt.
It is intended that the machinery to be erected by the Feather
River Company shall be capable of crushing and reducing the same
quantity at least of gold ore per annum as is minded and crushed by
the celebrated St. Juan del Rey Company of Brazil. ♦iz., about
60,800 tons per annum. The average produce of gold per ton, ob-
taint d by that company, as per their published reports, gives a value
of ij. 11 5. per ton, of ore only as contrasted with the above extraor-
dinary produce of 841. per ton. An average produce per ton of ore
of one-tenth only of this sum—say 81. per ton—must yield profits
lunch larger than the 20 per cent. dividend anticipated by the direc-
tor .

"In proot of his views ho (Mr. Courtenay) has given

"lel are cases ix., xi., xii., and xviii. No. ix. had resisted, for a
Period of twelve years, the treatment by &Illation, and was finally
removed in as many weeks. But cases xviii. and xix. appear, both
In duration, severity, and complication of symptoms, of a more ag-
gravated character than any detailed by Mr. Syme, and yet the
'treatment adopted by Mr. Courtenay proved eminently successful."
