MODE Oh STOPPING PoRCs CYLINDERS
FOR HYDRAULIC PREssEs.-Kohn, an engi-
neer in Berlin, gives the following as a
method of effectually stopping up porous
der is to be heated over a charcoal fire to about
one hundred and seventy degrees Fahrcn-
heit. 1t is then to be filed up with resin,
and suspended by crane over the fire
until the iquified resin is seen sweating
through on the outside. The excess of resin
is then poured out and the cylinder allowed
to cool, when the pores will be found COM
pletcly stopped, and no water can possibly
pass.
UTILIZATION OF COKE OVEN CASES.
Probably the first attempt to utilize the
gases given of in the process of coking has
been made at the works of Messrs. Carver
| g. Co., of st. Etienne. The gases are coll
lected, says the Mining journal, and drawn
off through pipes and cooled, when the tar
ammoniacal liquids, ETC., are condensed.
From these condensed liquids benZine, naph-
thaline, sulphate of ammonia, artificial man
| ures, and a number of dye stuffs, are made.
The gas remaining after condensation of the
| liquids, which is, of course, ordinary iIlum-
| mating gas, can be used in the usual man
ner. 1t is estimated that in France alone no
less than four millions tons of coal are an
| nually coked, and it has been proved that
Messrs. Carver's process is capable of Civ
ing profit of nearly 2s. upon every ton of
coal treated. more conclusive evidence of
the advantage resulting from that sound,
technical education SO readily obtainable on
the Continent, could scarcely be desired.
THE ACTION OF PUrR1pMArER1AL ON THE
ANIMAL ORGANIsM.-The following conclu-
sions have been derived by DR.. Moriz Hem
mer, of Munich, says the Btatter +. Stats
dr=neikmnde, from his researches on the ma
ture and action of putric fluids: 1. Putrid
infection causes severe acute Inflammation
in the intestinal mucous membrane and the
glands of the chylopoietic system. 9. 1t ex-
cites very violent central irritation. B. BY
it the blood is changed into dark-colored,
thin, and scarcely coagulable fluid. 4. It
causes the rapid approach of putrefaction.
5. The pntrid poison is an albuminoid body
undergoing change, not fluid or gaseous,
but solid. 6. The poison acts in impercep-
tibly small doses; and, with regard to it's
most active toxic agents known to us
some vegetable alkaloids, curare, the snake
poison, etc. Z. 1t is insoluble in absolute
alcohol, soluble in water. 3. 1t resists
heat of one hundred degree centigrade. 8.
1t acts as q ferment, and induces zymotic
changes in the blood. 10. The action of the
putrid poison is exerted on the albuminoid
materials of the p1asma of the blood. II.
An analogy may-generally be recognized
between putrid infection and the infectious
diseases. IL. The morbid materials of the
infectious diseases are, therefore, putrid
| same. l3. The varying action of the morbid
materials in the infectious diseases depends
upon a special modification of the putrid
poison. r --'f
THE NEW SCIENCE :-AToMEC1IA N1cs-
tThe importance of scientific discovery can
never be judged of by the manner of its re-
ceptien by the learned, for it not unfre-
quentfy happens that those which develop
the greatest truths are precisely those which
have the hardest struggle to obtain recogni-
ton they usually necessitate the use of
terms which are not familiar to us, and Of
ten require us to unlearn much that we
have learned, and to cause our thoughts to
flow in an entirely new channel. At a COM
paratively recent date, geology, now recog-
| nized rs a science of paramount Importance
in connection with almost every branch of
our national industry, was looked upon
considered to be either deluded enthusiasts
or impostors whilst at the present time the
science of atomechanics, or chemistry con-
sidered as the mechanics of the panatoms,
occupies position not very dissimilar to
that of geology at the, period referred to.
| The discovery of the existence of the panto-
gen, which may be regarded as the primary
chemical principle, just rs gravitation is the
primary mechanical principle, is due to
Gustav Hinrichs, and dates from the COM
mencement of the year 1855, when he was a
student in the Polytechnic School of Copen-
hagen, founded by Oersted, and at that time
under the superintendent of that distin-
guished chemist, the late Professor Ferct-
hammer. In 1856 and 1857 Hinrichs commu-
nieated a memoir upon atomechanics to va
rious sacdnts and academies in Europe, and
in his several papers, published between
1860 and 1866, reference to the subject has
frequently been made but it was not until
the present year that a complete outline of
the new science was printed, in the form of
a large quarto autographed memoir, trans
ferred from the authors own handwriting,
and deliberately illustrated with the neces-
sary diagrams.
