APPENDIX,

EXTRACT OF A LETTER FROM NICHOLAS GRAY. U.S., Surveyor to the
lion. T. 0. LARRIN. Dated Hamilton, June 11th, 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 correctly, or within the truth, so as
to hear future examination. I saw much richer specimens.
" This was dug out of a hole about 114 miles from Phoenix Mill
known as the Bloomingdale lege or le
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. The report of Messrs. Johnson and Matthey is as
follows :
" Assay-office, 79, Hatton-garden, London,
August 2s, 1852.
" The box of gold quartz had half of each piece taken off, and the
whole crushed together ve-y fine, giving grains of gold, which would
not pass through the sieve, equal to Suz. 10 dwt. of fine gold to the
ton of 20 cwt. The fine owder produced, by asmy, gold equal to
11oz. 10 dwt.S. 01 fine gold to the ton of 20 cwt.

20 oat the present price of fine gold—viz., 84s. 7d. per oz.—
gives a value of about 84/. to the ton of 20 cwt.
It is linefeed that the machinery to be erected by the Feather
River Company shall be capable of crushing and reducing the same
nantity at least of gold ore per annum as is minded and crushed by
the celebrated St. Juin del Key Company of Brazil, viz., about
60,000 tons per annum. The average produce of gold per ton, ob-
talm d by that company, as per their pubtshed reports, gives a value
of IL II s. 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 SI. per ton—must yield profits
much larger taa, tha 20 per cent. dividend anticipated by the dim-
tors,

In relation to the Treatmeut end Cue of Sufferers from Debility Of the
Generative System, lr Sexual Hypochondriasis.
Translated from the German of Dr. PICKFORD
"Dr. Pickford known to English readers by his frequent practi-
,:al contributions to German medical literature. This is the first
time, he informs us, that he has addressed himself to the nos-medi-
cal reader. We trust this may not be the last, if be shall
detect any other equally flagrant evil which it may be in his
rower to correct."—London Medical Gazette, May 30, 1851.
"We oromised in a former number that we should recur to this
war's, in order to exhibit its aim more clearly. The author lashes
with great severity the impostors who make a livelihood by preying
on the credulity of the public. The tribe of ' Quiet Symathisers,'
and • Medical Friends,' are mercilessly exposed; and if this book
could find its way into the hands of those who serer th com-
plaint of which it tre its, we are satisfied that m my h mdrecis would
be raved much needless suffering of body and mind, and what is of
less Importance, though it is that which tits quacks most prize—
much money... ...This volume is well qualified to put an end to the
empirical system of treating Spermatorrhcea, and to place the treat-
ment upon a more rational and physiological basis. It is, therefore,
likely to do much good."—Medical Circular, Jane 16, 1852.

and apparently Intractrble Forms.

BY F. B. COURTEITA7,
Member of the Royal College of Sus ,eons of England.
"In proof of his views he (Mr. Courtenay) has given
the history of a great many cases successfully treated, as bad
as any which Mr. Syme adduced, and on which ho had operated.
.ucir are cases ix., xi., xii., and xviii. No. ix. had res'sted, for a
period of twelve years, the treatment by dilitation, and waa finally
removed in as many weeks. But cases xviii. and xix. appear. \ both
in duraticn, severity, and complication of symptoms, of a More ag-
gravated character than any detailed by Mr. Byrne, and"yet the
, treatment adopted by Mr. Courtenay proved eminently gnectuftiv.
