The observations upon tr, e-growth in

show that in damp tropical climates the
concentric rings, from which the trees
age is usually calculated, may form at the
rate of one n month instead Of one a year.

Mons. Camille Flammarion, the

"A "bent equatorial" telescope, an in-
vention of Mons. Loewy. is now in opera
tion at the Paris Observatory. The pc.
culiarity of the instrument is that, in
consequence of the bending and the use
of two reftctiug mirrors the astronomer
can observe all the celestial bodies with
out rising from his table.
A distinguished German patbologist,
Prof. Schmale. advises all who wish to

preserve health.
In an experiment described to the
French Academy by Mons. Bergeron, a
miniature imitation of the craters in the
moon is produced by sending current
of hot air through brass tube into y
mass of melted but gradually cooling
metallic alloy. Mons. Bergeron looks
upon the experiment an suggestion of
the manner in which the lunar cratefs
may have been formed.
"A disastrous fire in Sicily sulphur
