Translated from 'he German of Dr. PICKFORD

"Dr. 11cifort1;;IC;;;;m to English readers by his frequent practi-
Ail contributions to German medical literature. This is the first
ime, he informs us, that be 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
over to correct."—London Medical Gazette, May 30, 1851.
"We promised in a former number that we should recur to this
wlr'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 Symatirlsers,'
and ' Medical Friends,' are mercilessly exposed ; arid if this book
could find its way into the hands of those who suffer fr >m th com-
plaint of which it treats, we are satisfied that many h indreds would
be saved much needless suffering of body and mind, and what is of
less Importance, though it is that which th quacks most prize—
much TV oney ......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, June 16, 1852.

TUE CURE OF STRICTURE OF THE URETIIRA; on Princi•
pies at once Simple, Safe, and Efficient, in even Its most Inveterate
and Apparently Intractable Forms.
BY F. B. COURTENAY,

Member of the Royal College of Surgeons of England.
"In proot of his views he (Mr. Courtenay) has given
the history of a great many cases successfully treated, as bad
as any which Mr. Spine adduced, and on which he had operated.
-tich are cases ix., xi., %IL, and avili. No. ix. had resisted, for a
period of twelve years, the treatment by dilitation, and was flnally
re noved in as many weeks. But cases xviii. and xix. appear, both
In climatical, severity, and complication of symptoms, of a more ag-
gravated character than any detailed by Mr. Syme, and yet the
treatraent adopted by Mr. Courtenay proved eminently successful."

IE .---- ,
Hackwork, engine-builders. This engine appears de-
stined to effect a great change in the use of steam-engines
either for the railway, the ship, or on common roads.
The simplicity of construction is such, that the inequali-
ties of surface on a common road, which have hitherto
deranged the machinery of the locomotive, are of no,
injury or detriment to the works. For the present
cumbrous marine-engine, it presents a substitute that
will not occupy half the room. It can be applied to every
purpose for which steam is applied, with the advantages
of fifty per cent. in the first cost being saved, and an
economy of twenty-five per cent. in fuel. In the con-
struction there is an entire absence of all dead points,
either of centre or crank, and it is of full power at every
point of its revolution—an advantage never attained in
any rotatory engine hitherto constructed. The cylinder is
of a peculiar shape, having two elliptical pistons on two
shafts, coupled with an ingenious contrivance to obviate
the noise of spur-wheels. A cylinder, eighteen inches
by nine inches, will give a power equal to ten horses.
The model we have seen at work, with a pressure of
401bs. per inch, performs two thousand revolutions in a
minute, on the axles of the pistons. It has been inspected
by engineers of the first eminence, and declared to be the
quickest fast-motion ever invented ; and as the wheels of
a carriage can be attached to the revolvinc, piston-rod,
any amount of speed may be obtained that' may be re-
quired. As a locomotive, it contains the greatest power
ever condensed into so small a compass ; as an air-pump
it will be found invaluable, as it entirely does away with
foot-valves. The packing in the pistons is peculiar,
and there is no stuffing next the revolving axle 6. A
company has been formed, in Stockton, to build a
steam-boat for pleasure excursions during the next
summer, to be worked by this engine ; and as it seems par-
ticularly adapted to ships, from its small size and great
power, it may be destined to carry out the problem ofsteam-
ships in the coal trade. As an engine for printing establish-
ments it must supersede every other. The one employed for
the Times in Printing-house-square will consume twenty-
five per cent. more in coal and steam than this will re-
quire. The simplicity of construction, is such that in a
steam-boat a man at the wheel can put on the steam,
shut it off, or reverse the engine, without moving from
his post, and only a stoker will be required below to keep
up the fire. As Mr. Elliott has not the means of carry-
ing out his patent, it is to be feared the benefit of it will
fall into the bands of some capitalist, who will be en-
riched by the efforts of a poor man's genius,—Sunder.
