ence of Atmosphsric Pressure on the Tides Pro;
" had made observations IN regard 10 this IN the
Bay OF Pensacola He observed that when The
barometer ranged high the tides were Away low,
and vice versa f: the ordinary mean range OF tue
barometer was % J0,; the ordinary ude range was
from 20 feet IN the Gull of Mexico Duflns a
stroag E. wind, with The barometer very low,
the ride at Pensacola would be very high; though
the tendency OF such wind would De 10 force me
water out OF the bav With the wind from The y
w the tide would be very low, whilst the weather
was very clear; change In the barometer 10 a
small extent ToglC frequently produce Use OF
from l to 8 feet IL the cde. and thus he thought
tide table might be made BY winch any COM
mander OF a vessel could know by MS barometer
how much wafer there would be on the bar OF a
certain harbor in the Gulf; and this was OF great
value because the depth of water on all the bars
IN the Gull Is very small, and al Pensacola II Is
onlv - feet. During y. W winds there, they
have generally clear weather, with the barometer
ranging high and the tides very low.
This was the substance OF the paper.

The President-Well, hope the public will get
an ample supply-equal TO their desires. (LaughteF)
MI Redfed said in relation TO Atmospheric
Pressure on tides. that hall an inch OF mercury
only made difference OF SIX inches IN the tide.
Or. Wedderburn has overrated The matter. So IN
! the case OF the y. Z. winds causing high tides
rise in the tide at Pensacola must be produced %
some cause operating cut OF that Bay nus y.
E wind a, Pensacoia would be an East wind at
Yucatap, and :. E. wind at another place, tom-
ing, as II were, circuit oil WINGS, all tending 70
drive the water into the Bay OF Pensacola.
Mr.. Rogers said that some years since, great
changes were observed in the level of the Swiss
Lakes IN times ef great stouns; and scientific men
in Switzerland called on us 10 observe if there were
similar changes IN our great Northern Lakes: Here
is great gauge 10 go by. Has any one made these
| observations On Lakes Enc or Superior Is u!efe
not some other force ct work, much more than
what IS due 10 static altered pressure Is there not
| a DYNAMIC force al work, as we'll as that al tnr
| change in superintendent column OF atmosphere!
| The dvzamic force oil the wind operating on Inc
waves OF lake, sustained through hours ana days
is of far more effect than static pressure as
indicated by the barometer.
Nj. -, said that in the Lake Onondasa. at
terra long storm, the winds would blow the water
high up on one side of the Lake and leaving 1t low
on the other He had made the same observations
on the action OF the wind on water. In still ar,
light wind olngs 10 the water, and moves surface

Prof Johnston of MlddIetown, SAID mat al the
gale of last September the barometer tell !. inch,
| and the tide rose 5 teet al Mddletown.
Prof LoonltS said that in the State OF Maine the
tide rises orr feet from long continued East WINDS;
there would be no storms but merely long contin-
| ued wind from the East. In one case the tide rose
from this cause so as 10 move log distance oil /"
or rods, winch had lain there for 90 years re-
membered by the Oldest nhabitani
Mr.. Johnston said that in the great gale of Sep
TENDER. 1921, the steamboat left \ ewHaven for
New-York there was great rise in the tde that
night the boat anchored off Morriss Cove there
was ledge OF rocks generally bare close by; the
boat parted her cable and was lifted clear over the
ledge safely into deep water by the Else OF the tlde
Prof Rogers said that much of this effect was
also owing to the peculiar properly of the adhesion
of wind 10 water, one OF the most beautiful laws
in the economy OF nature, otherwise the atmoS-
DASrt would SLUG over tilc suIidCC VI iIt SCh, h'N
all the beneficial effects OF storms would be lost
Another thought occurred 10 him: the ordinary
beat of the surf would not throw up those coral
reefs 10 the hlghh we find them: II Is done by The
whole mass Of the ocean pressed on by the trade
winds for long time that thHs pes teul up so idr
above the ocean level
Mr.. R,iteld made few observations on the Ell
fects produced on the shape of shores, By what
called converging waves, and their upheayaI force
A PAPER by Mr.. JVdaes on the Geology OF Mis-
sssipp was deferred as the specimens were not al
hand
A paper of Mr.. Jfebber Of Charleston, y. II. was
ordered for reading tomorrow 1t IS 90 On certain
forms of Attraction ~ whether il be the form Of
attraction presented by Ladies Bushes or not,
can't say twas laid on the able-uot the hustle,
bu, the paper
Prof Rogers said tina, the Committee of last year
had made call on the Secretary OF the Navy re-
quesng him 10 cause observations 10 be made IN
relation certain points in Hydrograpy. Meteorol-
ogy, Natural History, &c. &c. Now str. We propose
to send request 10 the Secretary OF War 10 lnst
tute a new and separate line OF inquiry on the great
subject of the level Of the Continent the observa-
lions 10 be made al the mean tide level; respecting
the oscillations OF this part OF North America. The
rise and fall, OF great part of the coast OF Scand-
aavla has been observed by Swedish Geolog,sts
and noted. And II is now pretty certain that no
part Of the earth's surface Is stationary.
Prof SiRin,an i should like 10 add enquiry into
subject am ignorant OF and have no means Of
informing myself about II il the average eeya-
| tioa OF continents above The level OF the sea.
The average elevation Of North America
II. The average elevation OF South America;
1.-THE average elevation Of Europe;
" The average elevation OF Asia,
V..The average elevation Of Africa.
By the deduction OF particulars from known data
we can come pretty nearly 10 a correct data
Prof. Rogrs.-Humboldt has published data
about the mean level OF certain lands He gives
the mean level of Asia 800 feet above the ocean;
and II is astonishing how small part the moua-
tains have 10 contribute 10 the earth's elevation.
SRiimGn.-Whst does he give, sir, as the eleva-
non OF North America.
Rogrs-Some FIVE or six hundred feet as The
average.
!SLlimam-Thatis even within my marx; have
said less than quarter of a mile, and then have
been thought rom, ncing; and even this may be
caused by the mass OF the Garth swelling bY ex-
| paGslon.
