BARON- LIEBIG'S OPINION of " PALE
ALES."
The prominence given to the name of Baron Liebig in pla,nards and
advertisements will have created the impression that he coveted a
celebrity inconsistent with the dignity of his station in the scientific
word. Having learned that he had attained such undesirable no•
toriety, Baron Liebig has requested the publieati3n of the following
letter, with the view of in,orming, the public of the motives which
dictated his communication to 'dr. Alls,app :
" The question of adulteration by strychnine, which has been
taken up seriously in England, seemed to me of great importance,
and I thought to do some good by a ding to demonstrate the error.
If I wished t) associate with any individual brewery my remarks on
the alleged adulteration of bitter beer with Strychnine, it would have
been only natural •to hive mentioned another brewery, in which
alone, and not in Mr. Allsopp's, I was engaged in investigating the
Burton mode of brewing,: and it was also -in that brewery, and not
in Mr. Allsopp's, thatllie Bavarian brewers acquired all the instruc-
tion they obtained at Burton. The admiration I expresA,d of this
beverage in my letter to Mr. Allsopp is advertised in such a manner
as to lead to the inference that my praise was exclusively confined
to Mr. Allsopp's beet; this was not the case, my remarks referred
to that class of beer. •

in relation to the Treatment and Cure of Sufferers from Debility of the
Generative Sy-tem, or Sexual HYpochrondriasis. Translated from
the German of Dr. PICKFORD,.,of .the University of Heidelberg.
Pickier i is known to English readers by his frequent practi-
cal contributions to German medical literature. This is the first
time, he informs us, that he has addressed himself to the non-medi-
cal reader. We trust this may not be the last, if he shall
detect any other equally flagrant evil which it may be in his
power to correct."—London Medical Gazette, May 30, 1851.
—" The editor has conferred a groat boon on the sufferers from this
distressing malady by translating this little book, and by laying bare
the scandalous practices of unqualified adventurers, who profess to
cure a disease of which they know nothing, with no other object
than to fill their own purses. The difference between true Sperma-
torrhcea and the various forms of disease which resemble it are
accurately described, and thus a safe guide is offered for the
treatment of the malady "—Medical Circular, May 5, 1852.
We have delayed so long upon the contents of the preliminary
chapter, that we have scarcely left ourselves space for any notice of
the subject specially treated of by Dr. Plckford ; but the moderate
price at which the ' brochure' is sold, places it within the reach of
every one interested in the matter."—Dublin Medical Press, April

" Tho.e who complain most loudly are those only who know not

about the simple cure of diseases, and a passion for operations and
all the excesses and horrors of surgery."—John Cell's Surgical
Observations.—" 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 he had operated.
Such are cases ix., xi., xii., and xviii. No. ix. had resisted, for a
period of twelve ye irs, the treatment by dilitation, and was finally
removed in as many weeks. But cases xviii. and xix. appear, both
in duratio", 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."

Notice—lt has frequ.ntly occurred that in papers
which have been considered deserving of being read and
published, and have even had premiums awarded to
',hem, the authors may have advanced somewhat doubt-
ful theories, or may have arrived at conclusions at vari-
ance with received opinions. The Council would, there-
fore, emphatically repeat, that the institution must not,
as a body, be considered responsible for the facts and
opinions advanced in the papers, or in the consequent
discussions; and it must be understood that such papers
may have medals and premiums awarded to them ou ac-
count of the science, talent, or industry displayed in the
consideration of the subject, and for the good which may
be expected to result from the discussion and the in-
quiry, but that such notice or award must not be consi-
dered as any expression of opinion on the • part of thp
institution of the correctness of any of the views enter-
tained by the authors of the papers.
