from 8 A.M., 2 P.M. and 8 P.M. observations in connection with the
minimum temperature, in which the minimum has a variable weight
dependent on place and month. The results of Koppen's formula tested on
six stations in widely different latitudes, indicate that it is of
value.
Paulsen's discussion of the warm winter winds of Greenland is
interesting. These unusual storm conditions last three or four days, or
even longer, the temperature being at times from 35° to 40° Fahr. above
the normal, and they appear principally with winds from northeast to
southeast, which Hoffmeyer believes to be _foehn_ winds. Paulsen
contends that the extensive region over which these winds occur make
the _foehn_ theory untenable, and that a more reasonable explanation of
these winds is to be found in the course of low areas passing along the
coast or over Greenland. This appears evident from the fact that not
the easterly winds only but the southerly winds share this high
temperature, and that as low areas approach from the west, at first the
regions of the Greenland coast within its influence have south to
southwest winds.
The question of wind pressures and wind velocities is a most important
one in these days of great engineering problems, particularly in
connection with the stability of bridges and other large structures.
Experimental determination of the constants of anemometric formulæ have
recently been made both in England and this country. From results
obtained in the English experiments it was concluded that the very
widely used Robinson anemometer is not as satisfactory and reliable an
instrument as a different form of anemometer devised by Mr. Dines.
These conclusions, however, are not sustained by the American
experiments, which were made by Professor C. F. Marvin, Signal Office,
by means of a whirling apparatus, and under the most favorable
circumstances, which yielded highly satisfactory results. Professor
Marvin has lately made very careful open air comparisons of anemometers
previously tested on the whirling machine, which have shown that, owing
in part to the irregular and gusty character of the wind movement in
the open air, taken in connection with the effects arising from the
moment of inertia of the cups, and the length of the arms of the
anemometer, the constants determined by whirling machine methods need
slight corrections and alterations to conform to the altered conditions
of exposure of the instruments in the open air. This latter problem is
now being experimentally studied at the Signal Office, and final
results will soon be worked out.
Professor Langley has also made very elaborate observations of
pressures on plane and other surfaces inclined to the normal, which it
is believed will prove important contributions to this question, but
the results have not yet been published. It is important in this
connection to note experiments made by Cooper on the Frith of Forth
Bridge, where a surface of 24 square metres, during a high wind,
experienced a maximum pressure of 132 kilogrammes per square metre,
while a surface of 14 square decimeters showed, under similar
conditions, 200 kilogrammes per square metre, by one instrument, and
170 by another. The opinion expressed by Cooper that in general the
more surface exposed to the wind, the less the pressure per unit of
surface, seems reasonable, and if verified by more elaborate
experiments must have an important bearing.
There are questions in connection with which even negative results are
of an important character, particularly when such results are quite
definite, and tend to remove one of many unknown elements from physical
problems of an intricate character. In this class may be placed
atmospheric electricity, with particular reference to its value in
connection with the forecast of coming weather. The Signal Office,
through Professor T. C. Mendenhall, a distinguished scientist
peculiarly fitted for work of this character, has been able to carry
out a series of observations, which have received from him careful
attention, both as to the conditions under which the observations were
made and in the elaboration of methods to be followed.
Professor Mendenhall also supervised the reduction of these
observations, and after careful study presented a full report of the
work to the National Academy of Sciences, in whose proceedings this
detailed report will appear. Professor Mendenhall says, "Taking all the
facts into consideration, it seems to be proved that the electrical
phenomena of the atmosphere are generally local in their character.
They do not promise, therefore, to be useful in weather forecasts,
although a close distribution of a large number of observers over a
comparatively small area would be useful in removing any doubt which
may still exist as to this question." It may be added that Professor
Mendenhall's conclusions bear out the opinions expressed to the
speaker, in a discussion of this question, by Professor Mascart, the
distinguished physicist.
It has been generally admitted that the aqueous vapor in the atmosphere
plays a most important part in bringing about the formation of storms
and maintaining their energy. It has been frequently commented on by
the forecast officials of the Signal Service, that storms passing over
the United States were in general preceded by an increase in moisture,
but unfortunately little effort had been made on the part of previous
investigators to determine any quantitative relation between the actual
humidity and the amount of precipitation or its relation to the storm
movement. It has long been regretted that the direct relations of this
to other meteorological phenomena were not more fully defined. During
the past year Captain James Allen, of the Signal Office, has endeavored
to apply the results of his investigations and theories to the
practical forecasts of storm conditions. Captain Allen has carefully
studied the relations of the potential energy of the surface air, as
represented by the total quantity of heat it contained, to the movement
of storm centres and the extent of accompanying rain areas. In his
first investigations the potential energy per cubic foot was estimated
as follows: Supposing the air to have been originally 32° and the
moisture in it as water at 32°, the total quantity of heat applied to
reduce to the state of observation will be A = (_t_-32)/6 + Q in which
A is total heat per unit volume; _t_ is the temperature of the air, Q
the total heat of vapor, and the specific heat of air at constant
volume being taken as one-sixth (.168). From Regnault's formula we have
Q = 1091.7 + .305(_t_-32).
For the mechanical equivalent we have J = 772A. If we divide J by the
pressure estimated in pounds per square foot, it will give the height
through which the pressure can be lifted if all the heat is spent in
work by expanding the air.
An approximate expression for the upward velocity V may be obtained
from Torrecelli's theorem from which we have V^2 = 2_gh_, _h_ in this
case being the height through which the pressure would be lifted if all
the heat is spent in work. The theory has been that the storm centre
will move over that section of the country where V is the greatest, and
that the time of occurrence and amount of rain have a relation of
conformity to the changes in Q and its actual amount.
Auxiliary charts were also made showing for each station the following
values of Q:
1st. Highest Q not followed by rain in 24 hours.
2d. Greatest plus change in Q not followed by rain in 24 hours.
3d. Lowest value for Q followed by rain in 12 hours.
A tentative application of the theory during December, 1889, has given
very encouraging results. The problem can be approached in many
different ways, but the basis of the solution is the determination of
the actual energy of the air, both potential and kinetic, as well as
differences of potential.
Probably the most important event of the past year to general
meteorological students has been the publication of Part I,
Temperature, and Part II, Moisture, of the Bibliography of Meteorology,
under the supervision of the Signal Office, and edited by Mr. O. L.
Fassig. The two parts cover 8,500 titles out of a total of about
60,000. This publication renders it now possible for any investigator
to review the complete literature of these subjects, not only with a
minimum loss of time, but with the advantage of supplementing his own
work, without duplication, by the investigations of his predecessors.
The publication is a lithographic reproduction of a type-written copy,
the only available method, which leaves much to be desired on the
grounds of appearance, space and clearness.

The experiments of Crova and Houdaille on Mount Venteux, elevation
1,907 metres, and at Bedoin, 309 metres, are of more than transient
interest since they fix the solar constant at a height of 1,907 metres,
at about three calories; agreeing with the value obtained by Langley on
Mt. Whitney, Cal.
With this brief allusion to the important phenomena of sun-heat,
whereon depend not only the subordinate manifestations pertaining to
this section, but those relating to all other departments, this report
may appropriately close.

REPORT OF AUDITING COMMITTEE.
December 27, 1889.
_To the National Geographic Society:_
The undersigned, having been appointed an auditing committee to examine
the account of the Treasurer for 1889, make the following report:
We have examined the Treasurer's books and find that the receipts as
therein stated are correctly reported. We have compared the
disbursements with the vouchers for the same and find them to have been
properly approved and correctly recorded. We have examined the bank
account and compared the checks accompanying the same. We find the
balance (beside the sum of $756.25 invested in real estate note) as
reported by the Treasurer ($63.82) consistent with the balance as shown
by the bankbook ($82.82), the difference being explained by the fact
that there are two outstanding checks for the sum of $19.00 not yet
presented for payment.

REPORT OF THE RECORDING SECRETARY.
The first report of the Secretaries was presented to the Society,
December 28, 1888. At that time the Society had a total membership of
209. Since that date this membership has been increased by the election
of 36 new members; it has been decreased by the death of 3 and by the
resignation of 14. The net increase in membership is thus 19 and the
present membership is 228, including 3 life members. The deceased
members are, Z. L. White, G. W. Dyer and Charles A. Ashburner.
The number of meetings held during the year was 17, of which 15 were
for the presentation and discussion of papers; one was a field meeting
held at Harper's Ferry, W. Va., on Saturday, May 11, 1889, and one, the
annual meeting. The average attendance was about 65.
The publication of a magazine begun last year, has been continued, and
three additional numbers have been published, being Nos. 2, 3 and 4 of
Vol. I. Copies of the numbers have been sent to all members and also to
about 75 American and foreign scientific societies and other
institutions interested in Geography. As a result the Society is now
steadily in receipt of geographical publications from various parts of
the world.
Respectfully submitted,
HENRY GANNETT, _Recording Secretary_.
