1 POLICE INTELLIGENCE.—(This Day.

SOUTHWARK.

ATTEMPT TO PICK POCKETS AT TUE SURREY
THEITRE.—WiIIiam bee, a well•dressed young fellow,
was brought before Mr. Combe, charged with attempting
to pick the pocket of Sarah Brown, at the pit of the
Surrey Theatre.

The prosecutor, the wife of a tradesmen, residing at
14, Francis-street, Waterloo-road, stated that about
half-past six o'clock on the previous evening she was at
the pit-office of the Surrey Theatre, and just as she had
paid her entrance money she felt some one at her dress
pocket, and, on looking down, she saw his hands inside.
She immediately called out, " You ♦agabond, I have
caught you this time ; you have got nothing for your
trouble." He then forced himself away from her, but a
constable came up and took him into custody. For-
tunately, she had nothing in her pocket but her hand-
kerchief, as she bad not returned her purse to her pocket,
consequently the prisoner would have been much dis-
appointed.

'ha prisoner here said that he was a respectable man,
and would not be guilty of such a❑ act. rise lady must
be mistaken as to his identity.
Mrs. Brown positively swore to his being the man,
as she actually caught hold of his hand while it was in
her pocket.

Henry Peckhpm, the constable of the Surrey Theatre,
said he was on duty near the entrance of the pit, shortly
after six o'olock, when he heard the last witness call
out "Police." He proceeded to the pit office and
took the prisoner into custody as he was attempting
to get away. He searched him, and he had nothing
upon him but a pawnbroker's duplicate and an old
handkerchief. He knew the prisoner well as a com-
panion of notorious thieves, and how he evaded his
observation by getting inside the doors he could not
tell, as he always kept a sharp look out for such fellows.
Mr. Combe asked the prisoner after that • evidence
would he go for trial or be tried by him I
He replied that he would be tried by his worship, and
he must plead guilty.

Mr. Combe sentenced the prisoner to three months'
hard labour under the New Criminal Justice Act.

TSB SELF-REGISTERING 21IEROVRIAL
TLIERMO Air ETER.

The following description of the self-registering mercu-
rial minimum thermometer, invented by Messrs. Negretti
and Zambra, of Hatton-garden, was read by Mr. Lee at
the recent meeting of the British Association at Chelten-
ham :—"The importance of a celf-registering mercurial
thermometer will be duly appreciated by any one interest-
ed in meteorological pursuits, when it is remembered that
all thermometers hitherto constructed for minimum pur•
poses have alcohol for the thermometrical fluid, on the plan
of Dr. Rutherford's thermometer. The unequal expansion
of alcohol at different degrees of heat has long caused a
self registering mercurial minimum thermometer to be-
come a desideratum ; for, if attained, then all thermometers
in a meteorological observatory would be constructed,
with one fluid, and that fluid the recognised standard of
heat. Impressed with the importance of this subject,
the inventors, so far back as 1851, shortly after the in-
troduction of their patent self-registering maximum ther-
mometer, applied themselves to the task of discovering
how a minimum thermometer could be made to answer
the requirements of those who desired accurate self-regis-
tering instruments. Thermometers of all shapes and make
were attempted by them, and when about to abandon the
idea, after experiments of four years' continuance, the
happy thought struck them that that which, in the old
Rutherford maximum was a defect, should now with a little
modification become the new patent minify:Mtn thermo-
meter. The task of keeping the steel index from plung-
ing into the mercury of a Rutherford maximum was the
great difficulty which parties using it had to contend
with ; for, when the index once entered the mercury, it
could not without great difficulty again be extracted. In
the thermometer now before us the endeavour i,, not to
prevent the index from entering the mercury, but to add
it in doing so as much as possible; or, rather, to assist
the mercury
to pass it, which is the same thing. The fol-
lowing is an endeavour to explain the construction of
this new instrument, and
ithen it will be better under-
stood upon what principle i t s constructed. The thermo-
meter, as shown by the diagram before us, has a bulb of
rather large size, consequently it allows of a tube corre-
sponding being large in the bore for that part forming
the scale. On the surface of the mercury enclosed in the
tube is placed a small steel needle, pointed at both ends,
which forms the index ; and it may be here remarked
that it is preferable to read the temperature from the
upper end of this steel needle enclosed in the tube, and
not from the mercury itself. This conical needle will
be capable of moving freely in the bore of the tube, and,
as the mercury descends therein, will of course fall with
it, but when the mercury ascends in the tube the mer-
cury will pass the lower pointed end of the needle, and
rise above the same without raising or moving the needle.
This latter will therefore remain stationary, and, con-
sequently, its upper point will indicate the lowest
temperature to which it has descended during the
12 or 24 hours, and will not be affected by any subse-
quent rise in the temperature. To reset the thermome-
ter for any future observations, it is necessary simply to
turn it in such a position that the mercury and needle in
the tube will flow into the reservoir at top. This it will
readily do, as there is no air above the mercury. Should
the needle not freely flow with the mercury into the re-
servoir, it may be assisted with a magnet, which may be
held there until, by returning the thermometer to the
upright position, the mercury flows back again into the
tube ; and then with the magnet the index may be re-
turned to the surface of the mercury ready for future
observations. One of the thermometers is now before
you, and can be examined by any one who feels inte-
rested in its success. In reply to any question that
may arise as to the probability of this thermometer
answering the purposes for which it was intended, it
may be remarked that, since November last, one has
been in the hands of the secretary of the British Meteo-
rological Society, and another at the Royal Observatory
at Greenwich, both of which have acted most accurately,
and in two instances have corrected errors in the alco-
hol minimums, which, but for it, would have passed
unnoticed. A few others have also been in use by gen-
tlemen who are well calculated to judge of their merits.
Among them we will mention Mr. E. J. Lowe, of Beeston
Observatory, near Nottingham ; also Mr. Drew, and two
or three members of the British Meteorological Society.
The inventors are fully aware that it is subject, like all
new instruments, to criticism ; but, he it perfect or im-
perfect, they present it before you as the first mercurial
self-registering. minimum thermometer that has ever
been invented. Should it, holtvever, meet with rely
half the success that their patent maximum thermometer
has done, they will be highly repaid for their exertions,
as upwards of 1,400 maximum thermometers are now in
the hands of the most scientific men of this country, and
not in one instance have they signally failed."
