Is it conceivable that a disk or plato Of air OF
rom three hundred to thousand miles 10 diameter,
and less than three miles in height, may oft. Own
accord assume whiting motion, capable OF pro-
ducing the terrific violence Of hurricane!
The exclusion Of !" all aid from foreign cluses'
would 10 cut off all assistance fro mech anical
eravltasion and from the rotary and orbitnal mo-
tons represented as indispensable to storms as al
ready stated In fact, The evidence here adduced
by tho author confutes his premises which ascribe all
windsand stoI nsto planetary motion to his
own allegations they may arise in isolated acr Al
mass Of the Dimensions above cited, without any
foreign aid, and Of course without the influence OF
planetary motion Moreover from the facts which he
states, it must be evident that such motions caa
have no storm producing influence on the isolated
masses OF air to which allusion has been made.
Again, the circumstances under which he repre-
sents storms TO originate, are such as to preclude
the influence OF any extraneous Storm producing
agents Their agency could not take place within
q .scalm re gion'' without destroying tho calm.
II seems to me that gales do not extend higher
than q MILE Mountains much less than a mile in
height usually penetrate the clouds which bound
According TO Redfeld, a storm may have any dia-
meter between three hundred and Thousand miles
IN extent. At three miles from tho terrestrial sur
face the air is only half dense at that surfaee
we may assume three miles the maximum OF
storm elevation. Imagine then plate Of air nine
hundred miles wide, and three miles high, and Of
course having s altitude to its diameter rs one 20
three hundred,
These proportions might be represented by an
electrical plate oil tenth OF inch in ihiokness
and thirty inches in diameter, Of two tenths Of
al inch in thickness and sixty inches or five feet
wide, when would agree with those OF the plate Of
q large electrical machine
BY wha. conceivable application Of forces could
such an acrifoyO mass be niods 20 rcvove, even il
Supported so 10 move without friction The glass
disk, II supported without friction, would
obedi. any taDgentia! force, because, in
que Of the Conference OF its parts, the motion Of
one pait involves that Of the whole. Moreover, at
ter being made 20 reyolve, tho consequent oenttu
gal force would be counierAced by the tenacty o
Us materials, but similar impulse would only push
off portion OF the aerial plale, disturbing Hut little
any portion which would bs remote from the pcint
OF application. TO cause the whole aerial mass 70
reyoive without derangemen5, and 80 to avoid
disruption, every particle must be acted upon ut the
same tims, by yelocties varying with tho distance
from the centre.
2 But the mass to be made to revolve existing ia
n part OF the atmosphere, aud there being seit
bodies IL nature wh'sh eau reach it, how can any
cause of motion affect it without disturbing the cir
cunalnbient quiescent air
What is there to isolate it from that mass so rs to
induce IN it separately violent gyration
10 any vhirlwind, travelling, as admitted, about
thirty miles hour, the velocity on side must
be thirty miles moIe ana on tho Other thirty m los
ess, than the velocity the limbs not affected by
the progressive motion. OF course, if the mean gy
ratory velocity be eighty miles the whole velocity
hundred and ten miles Inevitably, the violence
which conflicting bodies would experience woull
be as the squares OF these numbers, and, coase-
auently, the expenditure Of momentum would bs
nearly FIVE times great the southeastern
limb as ON the northwestern limb.
1t is in consequence Of this modification of the
rotary, by the travelling velocity, that the figure
representing the curtate cyeloid indicates neu-
tralization Of tho wbiring motion by the progress
sive motion at the spot where tho lines cross each
other Thus, the revolution of cycoid, less than
of circle, involves the existence of n space about
which the revolution is effected, and where conse
queny there is no motion and of course yioence;.
while on the outer boundary of the figure, the
curTenoe OF two veociries produces violence tho
square of their sum. How is this to be reconciled
with the allegation of Redield taat storms Ac5
with diminished violence towards the exterior and
with increased energy towards the interior of the
space which they occupy. "-S2tfaRan'S Journal, u.

about common axis. However, limited whir
may be produced by the conflict fcurrents meeting
at The focal area towards which they blow, accord
ing to the centripetal theory Of atorins.
But when whirl is produced by the conflict Of

The stratum of the atmosphere in which storms
take place is too shallow to admit of the generation
OF extensive whirs, Of which the diameter is pro-
baby never greater than the depth of the fluid in
which it takes place.
