THE Balloon Society of Great Britain
has been formed, its principal object be-
ing to bring together members of the
learned professions, scientific bodies,
and practical aeronauts, with a view to
having observations made in different
parts of the world wherever ascents take
place, whether by means of captive or
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

The result was startling, for the color

applied to the body produced no effect.

be 800 feet thick, and extends under an
area of ia acres. 1t lies at a depth OF
100 feet from the surface, and it is pro-
posed to mine it much after the manner
of anthracite coal. The salt bed is said

from September /, 1879, to May Is,

SIR ROBERT CHR1srIsoN, the great
Scotch chemist, has made some curious
observations on the effects of a cold,
wet season in diminishing the normal
growth of trees. He makes out, on
careful measurements, that comparing
1879 with 1873, eBven deciduous trees
not oaks-made on an average forty
one per cent. less growth in last year
than 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
heat appears to have more to do with
the making even of wood than moisture
has. 1t is strange that the GROWTH of
the oak, which drops its leaves, seems
less dependent on heat than that of the
pine, which we usually associate with
very cold regions; bat, perhaps, it need
not be the tree which is most stunted by
cold which is most easily killed by it.
The arrest of growth may sometimes
be a safeguard against vital injury.
