Mr. Roebiing, architect Of the Niagara
and Cincinnati suspensio1. bridges, is
about to undertake to Build one between
New York apd Brooklyn, at Fulton Ferry.
The bridgelwill be twieelas long and twice
as wide as'that across the Ohio at Cincin2
matt, supported by anjimmense pier in the
centre. This vast undertaking Mr.. Roeb-
ling proposes to make the croWning
achievement Of his life.
The pendulum experiments connected
with the great trigonometrical survey in
India, have shown that; contrary to pre-
vious theory, gravitatioh is less powerful
as we approach the Himalaya mountains ;

are less dense than those beneathYthe de

could be more probable, than the upheayed
portions of the crust should be the weakest.
1t is calculated that the deepest ote
which the human ear perceives as con
tinuous sound, is produced by sixteen vi
brations in a second; the acutest by $4,000
The extremes of color are red and violet :;
the former given by 458 billions of vibras

billions. The relative yelocities of light
and sound and the relative refinement of
the media through which their effects are,
conveyed, are illustrated by this =compari-
