became known, all over Bremen, that the 'lot of brass' which they
had carted so contemptuously to the police office, without putting
themselves to the trouble of pocketing the smallest scrap, was not only
gold--real gold--but gold far finer than any employed in coinage-gold,
in fact, absolutely pure, virgin, without the slightest appreciable
alloy.

I need not go over the details of Von Kempelen's confession (as far as
it went) and release, for these are familiar to the public. That he has
actually realized, in spirit and in effect, if not to the letter, the
old chimaera of the philosopher's stone, no sane person is at liberty
to doubt. The opinions of Arago are, of course, entitled to the greatest
consideration; but he is by no means infallible; and what he says of
bismuth, in his report to the Academy, must be taken cum grano salis.
The simple truth is, that up to this period all analysis has failed; and
until Von Kempelen chooses to let us have the key to his own published
enigma, it is more than probable that the matter will remain, for years,
in statu quo. All that as yet can fairly be said to be known is, that
'Pure gold can be made at will, and very readily from lead in connection
with certain other substances, in kind and in proportions, unknown.'

Speculation, of course, is busy as to the immediate and ultimate results
of this discovery--a discovery which few thinking persons will hesitate
in referring to an increased interest in the matter of gold generally,
by the late developments in California; and this reflection brings us
inevitably to another--the exceeding inopportuneness of Von Kempelen's
analysis. If many were prevented from adventuring to California, by the
mere apprehension that gold would so materially diminish in value,
on account of its plentifulness in the mines there, as to render
the speculation of going so far in search of it a doubtful one--what
impression will be wrought now, upon the minds of those about to
emigrate, and especially upon the minds of those actually in the
mineral region, by the announcement of this astounding discovery of Von
Kempelen? a discovery which declares, in so many words, that beyond its
intrinsic worth for manufacturing purposes (whatever that worth may be),
gold now is, or at least soon will be (for it cannot be supposed that
Von Kempelen can long retain his secret), of no greater value than
lead, and of far inferior value to silver. It is, indeed, exceedi
