Existing ConditionS-A lo,g of considerable
energy is central off the New Jersey coast

off the North Pacific coast. The principal high
is central in Dakota, moving rapidly southeast
ward. A high of small energy is moving east

elsewhere generally fair
Facts to be Reaembered.-1. If a globe Is
inches in diameter be taken to represent the
earth, the greatest known depth of the ocean
and hight of the highest mountain would be
represented by one hundredth part of an
inch, and the hight of the atmosphere, on
similar scale, by about onefftieth part of an
inch.
2. In round numbers, 10 cubic feet of dry air
weigh one pound avoirdupois, and in all re-
spects air follows the same laws as ordinary
cases. the density being greatest near the sur
face of the earth, and decreasing upwards, so
that at an elevation of seven miles it is reduced
to one quarter, at IA miles to one-sixteenth,
and at 81 miles to one sixty-fourth of what it
is at the surface.
B. In the celebrated balloon ascent by Clash
er, in 1862, at an elevation of $1,000 feet the
barometer had fallen to 11.53 inches.
d Dry air at $40 Fair. can sustain, in an in
visible form, a one-hundred- and -sxtieth part of
its own weight of aqueous vapor; at $50 Fair.
one-eightieth, and at $50 Fair. e-fortieth, it's
capacity being thus doubled every 27o Fair.
