r The Claspers were the favourites, at even agaiast any
other crew; and the Oxford watermen app- aced to be in
soave request. They effected a very excellent start,
immediately after which the Agnes went in advance with
a slight lead, which they had increased to a length at
the committee-barge, the other three laying almost in ft
line across the Thames. The contest was continued with
great spirit, the Agnes having a slight lead up to the
high bridge, where, in consequence of their shooting too
much into the bight, they fouled the' Wandsworth crew,
which had the of ,ct of creating a slight stoppage to the
Chelsea boat. The Oxford men, who kept a very good
course in the race, then went well in advance ; winnieg
by a length and a half. The Agnes crew were
ranch
chagrined at their mishap.

POLYTECHNIC INSTITUTION.
It is at once surprising and gratifying to observe the
, crowds who flock daily to this noble temple of practical
science, to enjoy the vast treasures of instruction and
entertainment which are presented here, notwithstand-
ing the innumerable temptations to out-of-door amuse-
ments scattered at this season in every direction,
throughout the sylvan menageries, the public conserva-
tories, and the histrionic gardens around the metropolis;
and it is a matter of great credit to the management of
the institution that the ventilation and temperature are
so agreeably regulated in the thronged halls, galleries, and
theatres of the institution, during the tropical heat
which has prevailed for some dep. At no period have
the varied lectures been more attractive or instructive,
and the successive audiences appear, from month to
month, advancing in the intelligence and interest with
which they attend to them. This, of course, must in
some measure be accounted for by the acknowledged
improvement of the public taste in the appreciation of
the most refined sources of pleasure; but still very
much is due to the singular excellence of the
Polytechnic professors, in the clearness and sim-
plicity of their discourses, which render the most
recondite learning popular, and the most abstruse
science intelligible even to the child. The surpass-
ing merit of Dr. Richhoffner in this respect is sufficiently
well known to our readers, and it is only those alio
frequently attend his lectures that can do justice to the
easy good humour and temperate gaie:ty with which he
enlivens the driest subjects, and the tin laboured eloquence
of diction with which be untillds the riches of science to
his charmed auditories. hlis example, and that of his
l•ete highly gifted coadjutor, Dr. Ryan, seem to a great
degree to influence the several professors who ar• trots
time to time associated in the grand objects of the eats.
blishment. The principal subject of Dr. Bachhoffner's
present series of lectures is the production of artificial ice,
and the experiments with which they are illustrated very
much surpass in beauty and interest anything that could
be anticipated. The process which the Learned Pro-
teaser has to explain is the invention of Mr. Masters, of
hi: g' at•street, confectioner, who is known to the puhlio
as a mechanical inventor of a rest success end ingenuity,
of which his knife-cleaning and sharpening apparatus is
a very remarkable and useful example. The freesing
iaventiou is likely to exceed very far indeed most others
of the day in its hitherto =bought-A utility, for, as we
have beard a philosophic auditor of Protissor Bachhoff-
aer's observe, last evening in the lecture-room, " we may
soon expect to see Mr. Masters adapt the principle of
these apparatus to the reduction of temperature in hos-
t itals, and in the mansions of tropical climates, so that
t' e British East Indian may enjoy at Calcutta the re-
et'.!shment of his present sanatorium on the lower
llunalayas!" About thirty years ago Professor Leslie
produced a freezing apparatus by which he oonfidently
predicted that. we should be able to produce ice on a
large scale in the hottest climates of the glebe. But, al-
though his apparatus was perfectly successful in fact, yet it
was found more expensive or less con►enient than the
application of natural ice to the ordinary purposes of the
confectioner, and the butler, and even of the physician,
wh•. seems to have been but little thought of in relation
liicrtide d";t:kilit !Flit !lain 15ST Tr hils- inventive - :
tions. Leslie's apparatus never came into use. Natural,
or ea it is called technically, " rough " ice, continues to
be the great refrigerator, and not only temperate and
southern Europe, but Egypt, India, and even China, re.
ceive large and expensive supplies from North America.,
so that the ice trade has been a staple branch of
American commerce, which, however, is destined ho re-
ceive at least a check from this important invention; for
it is demonstrated that four quarts of pure spring
water are converted into solid chrystal ice, whilit,
in the same process, and simultaneously, that is,
in four minutes, two quarts of dessert ice ready
mixed, and flavoured with cherry, lemon, ginger, or
what you like, may be produced, at the expense of
less than one penny, and kept cold and firm on the
table for hours, on the hottest day—in Calcutta or Hong
Kong ! Masters' apparatus for the parpose is a small
rotary churn, worked easily by a child, costing but little,
and scarcely larger than a common tea-urn. Besides
this, all the varied apparatus of Masters for supplying
and applying ice, exhibited by Dr. Bachhoffner, are of the
most elegant forms, and of no more than the ordinary
bulk of the decanters, bacons, jugs, and other ornaments
of the table and sideboard. One very beautiful vessel,
about the size of the ordinary funnel affixed for a moment
to the neck of a decanter, serves to strain and ice instan-
taneously the wine poured through it from the bottle. A.
decanter stand or tray, of elegant fashion and common
size, is contrived to keep your wine coo►, or cold (if you
like) to the end of the feast. Butter, by
similar means, is kept firm and sweet ;
water, wine, or lemonade, cool, upon the
sideboard all the dog-days through. And, by the bye,
the churn is equally applicable to the making of butter
as of ice, with an equal saving of labour and expense.
Ice creams and water-ices are e hipped and beaten up
while in the act of freezing—at the rate of a dessert
fur 300 persons in twenty minutes—at the coat of one
person's attendance, and about one halfpenny per quart.
Yet far more important, although less profitable to the
inventor, is the metallic cap, which Dr. Bachhoffner ex-
hibited last night, for application to the bead, in those
t
desperate and painful cases in which the applii..ationho
ice is resorted to. Ice is not always. at hand.bTe

sight appears will doubtless result from an extended ap-
plication of these inventions.

FRIGHTFUL ACCIDENT AT NEWMARILET.—A most
dreadful accident occurred here on Tuesday

Miss Julia Marson, by which it is feared the
most amiable yoang lady will be sacrificed. Mrs. Marson
t
was superintending the makii'g of some preserves, when
Nlisa Marson entered the kitchen to speak to her mother.
She went close to the tire, and having on a muslin dress,
it is supposed a gush of air carried it near the bars. In
one instant she was in a sheet of fire. Mr. Maroon ran
down from his bedroom on hearing the dreadful screams,
and a Mr. myth, who had jest left the house, and was
not more than a hundred yards off, hearing the cries,
returned, caught the poor girl in his arms, put her on
the ground, and extinguished the remaining flames, but
scarcely a vestige was then left of her clothing. Sur-
gical assistance was immediately sent for and the lady

BANK-NOTES.—All il IT.
nportant invention , for pro-
ducing watermarks •in all kinCs of paper,andparticu-
larly
adapted for bank-notes
be and paper requiring secu-
rity from forgeries, has been patented by the inventors,
Messrs. W. Brewer and Ten
New-street, Clapham. The Smith, 'of Malcolm Works,
invention produces an unli-
mited series of any given design in watermark with pre-
cise similarity, which cannot be produced by the method
now employed, in which wires are used. The watermark
is produced without wire, and therefore the repairing of
tho wires is unnecessary. The time saved is almost as
a hundred to one in comparison with the hitherto known
processes, and the durability of the means employed in-
finitely in-cater. The results are the prevention of for-
gery, and' the saving of time, labour, and expense.
