ELASTIC, springy wheels of the bicy-
ele pattern can be used very advantage
ousiy on carriages, IL is said. Made OF
steel, nickel plated, and with rubber
tire, they cost about third more than
the best wooden wheels. but are more
durable and easier for riding.
! THE proposed tunnel through Mont
Blanc is being seriously talked about in
France and the French Government
have commissioned NJ. de Lepinaye TO
draw up a report of the scheme. The
estimated cost is $50. 00o, 900, and the
extreme length would be about eight
miles. FlnF rrH r..
THE Balloon Society of Great Britain

ing to bring together members of the
learned professions, scientific bodies,
and practical aeronauts, with view to

free balloons.
AFTER the execution of Menesclou in
Paris the other day for the murder OF
the little girl, Louise Deu, his remains
were conveyed to the anatomical thea
ter, and subjected to singular expert
ment. DIR. Sappey injected under the
cutaneous tissue of the head some fresh
drawn blood from the carotid of a dog.
The result was startling, for the color
returned TO the cheeks, there was per-
ceptible nervous tremor, while the lips
slightly moved. The same treatment
applied to the body produced no effect.
A PENNSYLVANIA manufacturing
company has received large order for
machinery to be used in the develop
ment of an extensive salt mile ut New
Iberia, La. The salt deposit is said to
be 800 feet thick, and extends under an
area of Ia acres. Ii lies at depth OF
100 feet from the surface, and 1t Is pro-
posed to mine it much after the manner
of anthracite coal. The salt bed Is said
to be the greatest in the world. The
farm of Joseph jefferson adjoins the
territory under which the vein extends.
BALTIMORE packs more oysters than
any other city in the world, fifteen firms

SIR ROBERT CHRIsrIsoN, the great
Scotch chemist, has made some curious
on the effects Of cold,
wet season in diminishing the normal
growth of trees. He makes out, on
careful measurements, that comparing
1879 with 1878, eleven deciduous trees
not oaks-made on an average forty
,ne per cent. less growth in last year
han in the year before. OF seventeen
pine trees, the average deficiency was
twenty per cent, and of seven oaks the
deficiency was ten per cent; so that
neat appears to have more TO do with
he making even of wood than moisture
iss. 1t is strange that the growth Of
he oak, which drops its leaves, seems
ess dependent on heat than that of the
pine, which we usually associate with
,ery cold regions; but, perhaps, 1t need
rot be the tree which is most stunted by
,old which is most easily killed by Il.
The arrest of growth may sometimes
