PREFACE TO REVISED EDITION.
The original edition of Smithsonian Meteorological Tables, issued in
1893, having become exhausted, necessitating a second edition, a care-
ful examination of the original work has been made, at my request, by
Mr. Alexander McAdie, of the United States Weather Bureau.
All errata thus far detected have been corrected upon the plates,
and a few slight changes have been made. The International Meteoro-
logical Symbols and an Index have been added.

PREFACE
In connection with the system of meteorological observations estab-
lished by the Smithsonian Institution about 1850, a collection of
meteorological tables was compiled by Dr. ARNOLD GUYOT, at the
request of Secretary HENRY, and published in 1852 as a volume of the
Miscellaneous Collections.
Five years later, in 1857, a second edition was published after
careful revision by the author, and the various series of tables were
so enlarged as to extend the work from 212 to over 600 pages.
In 1859 a third edition was published, with further amendments.
Although designed primarily for the meteorological observers report-
ing to the Smithsonian Institution, the tables obtained a much wider
circulation, and were extensively used by meteorologists and physicists
in Europe and in the United States.
After twenty-five years of valuable service, the work was again
revised by the author ; and the fourth edition, containing over 700
pages, was published in 1884. Before finishing the last few tables,
Dr. GUYOT died, and the completion of the work was intrusted to his
assistant, Prof. WM. LIBBEY, JR., who executed the duties of final editor.
In a few years the demand for the tables exhausted the edition,
and thereupon it appeared desirable to recast entirely the work. After
very careful consideration, I decided to publish the new tables in
three parts: METEOROLOGICAL TABLES, GEOGRAPHICAL TABLES, and
PHYSICAL TABLES, each representative of the latest knowledge in its
field, and independent of the others ; but the three forming a homo-
geneous series.
Although thus historically related to Dr. Guy of s Tables, the present
work is so substantially changed with respect to material, arrange-
ment, and presentation that it is not a fifth edition of the older tables,
but essentially a new publication.
vi PREFACE.
In its preparation the advantage of conformity with the recently
issued International Meteorological Tables has been kept steadily in view,
and so far as consistent with other decisions, the constants and methods
there employed have been followed. The most important difference in
constants is the relation of the yard to the metre. The value provi-
sionally adopted by the Bureau of Weights and Measures of the United
States Coast and Geodetic Survey,
i metre = 39.3700 inches,
has been used here in the conversion-tables of metric and English
linear measures, and in the transformation of all formulae involving
such conversions.
A large number of tables have been newly computed ; those taken
from the International Meteorological Tables and other official sources
are credited in the introduction.
To Prof. WM. LIBBEY, JR., especial acknowledgments are due for
a large amount of attention given to the present work. Prof. LIBBEY
had already completed a revision, involving considerable recomputation,
of the meteorological tables contained in the last edition of Guyot's
Tables, when it was determined to adopt new values for many of the
constants, and to have the present volume set with new type. This
involved a large amount of new computation, which was placed under
the direction of Mr. GEORGE E. CURTIS, who has also written the
text, and has carefully prepared the whole manuscript and carried it
through the press. To Mr. Curtis' s interest, and to his special experi-
ence as a meteorologist, the present volume is therefore largely due.
Prof. LIBBEY has contributed Tables 38, 39, 55, 56, 61, 74, 77, 89,
and 90, and has also read the proof-sheets of the entire work.
I desire to express my acknowledgments to Prof. CLEVELAND ABBE,
for the manuscript of Tables 32, 81, 82, 83, 84, 85, 86; to Mr. H. A.
HAZEN, for Tables 49, 50, 94, 95, 96, which have been taken from his
Hand-book of Meteorological Tables ; and also to the Superintendent of
the United States Coast and Geodetic Survey, the Chief Signal Officer
of the Army, and the Chief of the Weather Bureau, for much valuable
counsel during the progress of the work.

Conversion of readings of the Reaumur thermometer to readings
TABLE 1
of the Fahrenheit and Centigrade thermometers.
The argument is given for every Reaumur degree from -f 80 to 40
Reaumur, and the corresponding readings Fahrenheit and Centigrade are
given to hundredths of a degree, permitting the exact values to be
expressed. A column of proportional parts gives the values corresponding
to tenths of a Reaumur degree. By the help of the column of proportional
parts, the table is also conveniently used for converting Fahrenheit to
Centigrade and Reaumur, and Centigrade to Fahrenheit and Reaumur
throughout the thermometric scale from the boiling point of water to
60 F. or 51 C.
The formulae expressing the relation between the different scales are
given at the bottom of the table, where
F = Temperature Fahrenheit.
C = Temperature Centigrade.
R = Temperature Reaumur.
Examples :
To convert i8.3 Reaumur to Fahrenheit and Centigrade.
From the table, i8.o R. = 7 2 50 F. = 22^50 C.
From column Prop. Parts, 0.3 = 0.675 = -375
18^3 R. = 73.2 F. = 22.9 C.
To convert i47-7 Fahrenheit to Centigrade and Reaumur.
From the table, i46.75 F. = 63:75 C. = 5ioR.
From column Prop. Parts, 0.95 = 0.53 = 0.4
i 47 .7 F.= 6 4 r 3 C. = 5
To convert i6.9 Centigrade to Fahrenheit and Reaumur.
From the table, i6.25 C. = 61:25 F. = 13*0 R.
From column Prop. Parts, 0.65 = 1.17 = 0.5
16:9 C= 62.4 F. = itfsR.

TABLE 2. Conversion of readings of the Fahrenheit thermometer to readings
Centigrade.
The conversion of Fahrenheit temperatures to Centigrade temperatures
is given for every tenth of a degree from + 130:9 F. to jolqF. The
side argument is the whole number of degrees Fahrenheit, and the top
argument, tenths of a degree Fahrenheit ; interpolation to hundredths of a
degree, when desired, is readily effected mentally. The tabular values are
given to hundredths of a degree Centigrade.
The formula for conversion is
C=| (F--32-)
where F is a given temperature Fahrenheit, and C the corresponding
temperature Centigrade.
Example :
To convert 79:7 Fahrenheit to Centigrade.
The table gives directly 26.5O C.
For conversions of temperatures above 13 i / 7 , use Table i.
TABLE 3. Conversion of readings of the Centigrade thermometer to readings
Fahrenheit.
The conversion of Centigrade temperatures to Fahrenheit temperatures
is given for every tenth of a degree Centigrade from -f- 5o.9 to 5O.9 C.
The tabular values are expressed in hundredths of a degree Fahrenheit.
The formula for conversion is
where C is a given temperature Centigrade, and F the corresponding
temperature Fahrenheit.
For conversions of temperatures above the upper limit of the table,
use Tables i and 4.
TABLE 4. Conversion of readings of the Centigrade thermometer near the
boiling point to readings Fahrenheit.
This is an extension of Table 3 from 90^0 to ioo.9 Centigrade.
Example :
To convert 95:74 Centigrade to Fahrenheit.
From the table, 95?o C. = 204:26 F.
By interpolation, 0.04 = 0.07
95.74 C. = 204:33 F.

REDUCTION OF TEMPERATURE TO SEA I.EVEI,.
English Measures. TABLE 7.
Metric Measures. TABLE 8.
These tables give for different altitudes and for different uniform rates
of decrease of temperature with altitude, the amount in hundredths of a
degree Fahrenheit and Centigrade, which must be added to observed tem-
peratures in order to reduce them to sea level.
The rate of decrease of temperature with altitude varies from one
region to another, and in the same region varies according to the season
and the meteorological conditions ; being in general greater in warm lati-
tudes than in cold ones, greater in summer than in winter, and greater
in cyclones than in anti-cyclones. For continental plateau regions, the
reduction often becomes fictitious or illusory. The use of the tables there-
fore requires experience and judgment in selecting the rate of decrease
of temperature to be used.
The tables are given in order to facilitate the reduction of temperature
either upwards or downwards in special investigations, but the reduction is
not ordinarily applied to meteorological observations.
The tables, 7 and 8, are computed for rates of temperature change
ranging from i Fahrenheit in 200 feet to i Fahrenheit in 900 feet, and
from i Centigrade in 100 metres to i Centigrade in 500 metres ; and
for altitudes up to 5,000 feet and 3,000 metres respectively.

CORRECTION FOR THE TEMPERATURE OF THE MERCURY IN THE THER-
MOMETER STEM.
TABLES. Fahrenheit thermometers ; Centigrade thermometers.
When the temperature of the thermometer stem is materiall}- differ-
ent from that of the bulb, a correction needs to be applied to the observed
reading in order to correct it for the difference in the length of the mer-
cury column caused by this difference in its temperature. This correction
frequently becomes necessary in physical experiments where the bulb only
is immersed in a bath whose temperature is to be determined, and in
meteorological observations it may become appreciable in wet-bulb, dew
point, and solar radiation thermometers, when the temperature of the bulb
is considerably above or below the air temperature.
If f be the average temperature of the mercury column, t the observed
reading of the thermometer, n the length of mercury in the stem in scale
degrees, and a the apparent expansion of mercury in glass for i, the
correction is given by the expression
an (f /)
in which, for Centigrade temperatures, a = 0.000154 or 0.000155.
The average temperature of the mercury column can not be directly
observed and is difficult to determine, for it differs from the temperature
of the glass stem by an amount depending on the conduction of heat
between the bulb and the mercury column. Practically however it is
possible to use the actually observed temperature of the glass stem as the
value of f by making a small compensating change in the value of a,
and this appears to be the simplest method that has been proposed. Mr.
T. E. Thorpe (Journal of the Chemical Society, vol. 37, 1880, p. 160) has
determined by a series of experiments that the proper thermometric cor-
rections will be obtained by this method if 0.000143 be used as a coefficient
(for Centigrade temperatures) instead of the value of a given above, and
this value has been adopted in the present tables.
The correction formulae are, then,
T= t 0.0000795 n (f t} Temperature Fahrenheit.
T*=- t 0.000143 n (f O Temperature Centigrade,
in which T= Corrected temperature.
t = Observed temperature.
f = Mean temperature of the glass stem.
n = Length of mercury in the stem in scale degrees.
BAROMETRICAL TABLES. XV
When f is \ s icttw:i \ than /, the numerical correction is to be I
I less J I
Example :
The observed temperature of a black bulb thermometer is 120^4 F., the
temperature of the glass stem is 55.2 F. and the length of mercury
in the stem is 130 F. To find the corrected temperature.
With n = 130 F. and / 7 /= [ ] 65 F., as arguments, the table gives
the correction 0^7 F., which by the above rule is to be added to the
observed temperature. The corrected temperature is therefore 1 2 1 .i F.
BAROMETRICAL TABLES.
REDUCTION TO A STANDARD TEMPERATURE OF OBSERVATIONS MADE
WITH BAROMETERS HAVING BRASS SCALES.
The indicated height of the mercurial column in a barometer varies not
only with changes of atmospheric pressure, but also with variations of the
temperature of the mercury and of the scale. It is evident therefore that
if the height of the barometric column is to be a true relative measure of
atmospheric pressure, the observed readings must be reduced to the values
they would have if the mercury and scale were maintained at a constant
standard temperature.
This reduction is known as the reduction for temperature, and combines
both the correction for the expansion of the mercury and that for the expan-
sion of the scale, on the assumption that the attached thermometer gives the
temperature both of the mercury and of the scale.
The freezing point is universally adopted as the standard temperature
of the mercury, to which all readings are to be reduced. The temperature
to which the scale is reduced is the normal or standard temperature of the
adopted standard of length. For English scales, which depend upon the
English yard, this is 62 Fahrenheit. For metric scales, which depend
upon the metre, it is o Centigrade.
As thus reduced, observations made with English and metric barometers
become perfectly comparable when converted by the ordinary tables of linear
conversion, viz.: millimetres to inches and inches to millimetres (see Tables
64, 65), for these conversions refer to the metre at o Centigrade and the
English yard at 62 Fahrenheit.
The general formula for reducing barometric readings to a standard tem-
perature is
l+m(t -T}
Xvi INTRODUCTION.
in which C= Correction for temperature.
B = Observed height of the barometric column.
/ = Temperature of the attached thermometer.
T= Standard temperature of the mercury.
m = Coefficient of expansion of mercury.
/ = Coefficient of linear expansion of brass.
= Standard temperature of the scale.
The accepted determination of the coefficient of expansion of mercury
is that given by Broch's reduction of Regnault's experiments, viz :
m (for i C) = io"9(i8i792 -{- 0.175/4- 0.0351 16/ 2 ).
As a sufficiently accurate approximation, the intermediate value
m = 0.0001818
has been adopted uniformly for all temperatures in conformity with the usage
of the International Meteorological Tables.
Various specimens of brass scales made of alloys of different com-
position show differences in their coefficients of expansion amounting to
eight and sometimes ten per cent, of the total amount. The Smithsonian
Tables prepared by Prof. Guyot were computed with the average value
/(for i C) = 0.0000188 ; for the sake of uniformity with the International
Meteorological Tables, the value
7 = 0.0000184
has been used in the present volume. For any individual scale, either value
may easily be in error by four per cent.
A small portion of the tables has been independently computed, but the
larger part of the values have been copied from the International Meteoro-
logical Tables, one inaccuracy having been found and corrected.
TABLE 10. Reduction of the barometer to standard temperature English
measures.
For the English barometer the formula for reducing observed readings
to a standard temperature becomes

in which B = Observed height of the barometer in English inches.
/ = Temperature of attached thermometer in degrees Fahrenheit.
m 0.0001818 X | = o.oooioi
/ = 0.0000184 X | 0.0000102
The combined reduction of the mercury to the freezing point and of the
scale to 62 Fahrenheit brings the point of no correction to approximately
BAROMETRICAL TABLES. Xvii
28 5 Fahrenheit, and this is therefore the standard temperature to which
all readings are reduced. For temperatures above 28.5 Fahrenheit, the
correction is subtractive, and for temperatures below 28. 5 Fahrenheit, the
correction is additive, as indicated by the signs ( + ) and ( ) inserted
throughout the table.
The table gives the corrections for every half degree Fahrenheit from
o to ioo. The limits of pressure are 19 and 31.6 inches, the corrections
being computed for every half inch from 19 to 24 inches, and for every
two- tenths of an inch from 24 to 31.6 inches.

TABLE 11.
TABLE 11. Reduction of the barometer to standard temperature Metric
measures.
For the metric barometer the formula for reducing observed readings to
the standard temperature, o C., becomes
i + mt
in which C and B are expressed in millimetres and t in Centigrade
degrees.
m 0.0001818 ; / = 0.0000184.
In the tables, the limits adopted for the pressure are 440 and 795 mil-
limetres, the intervals being 10 millimetres between 440 and 600 milli-
metres, and 5 millimetres between 600 and 795 millimetres
The limits adopted for the temperature are o + and -f- 35.8, the
intervals being o.5 and i.o from 440 to 560 millimetres, and o.2 from 560
to 795 millimetres.
For temperatures above o Centigrade the correction is negative, and
hence is to be subtracted from the observed readings.
For temperatures below o Centigrade the correction is positive, and
from o C. down to 20 C. the numerical values thereof, for ordinary baro-
metric work, do not materially differ from the values for the corresponding
temperatures above o C. Thus the correction for 9 C. is numerically
the same as for + 9 C. and is taken from the table. In physical work of
extreme precision, the numerical values given for positive temperatures may
be. used for temperatures below o C. by applying to them the following
corrections :

REDUCTION OF THE BAROMETER TO STANDARD GRAVITY
AT LATITUDE 45 f
The atmospheric pressure is measured by the weight of the mer-
curial column of the barometer, but by common usage the pressures are
expressed in terms of the height of the barometric column instead of by
its weight. The observed height however is not a true measure of the
pressure, because it changes with the temperature of the mercury and
with the variations in the value of gravity. Therefore to obtain a height
that shall be a true relative measure of the atmospheric pressure, the ob-
served height of the mercurial column must be reduced to that which
would be measured at a standard temperature and under a uniform stand-
ard value of gravity.
BAROMETRICAL TABLES. xix
The standard value of gravity adopted is that prevailing at latitude
45 and sea level. The reduction, accordingly, consists of two parts a
correction for altitude and a correction for latitude. The gravity correc-
tion for altitude is usually combined with the reduction of the barometer
to sea level ; the gravity correction for latitude, which is here given, is
commonly called simply the "gravity correction," or the "reduction to
standard gravity."
If B$ and B^ represent the barometric heights (corrected for tem-
perature) at latitudes <f> and 45, and g$, g^ the acceleration of gravity

REDUCTION OF THE BAROMETER TO SEA
The fundamental formula for reducing the barometer to sea level and
for determining heights by the barometer is the original formula of Laplace,
amplified into the following form
in which h = Height of the upper station.
h = Height of the lower station.
Z=h h .
p = Atmospheric pressure at the upper station.
p Atmospheric pressure at the lower station.
R = Mean radius of the earth.

h and h .
e Mean pressure of aqueous vapor in the air column.
b = Mean barometric pressure of the air column.

K= Barometric constant.

k = Constant depending on the figure of the earth.
The pressures p and p are computed from the height of the column of

mercury at the two stations ; the ratio - of the barometric heights may be

substituted for the ratio ^7, if B and B are reduced to the values that would
P
be measured at the same temperature and under the same relative value of
gravity.
The correction of the observed barometric heights for instrumental tem-
perature is always separately made, but the correction for the variation of
gravity with altitude is generally introduced into the formula itself.
If B , B represent the barometric heights corrected for temperature only,
we have the equation

in treating of this humidity factor in connection with hypsometric tables
took the following position :
-
' ' To introduce a separate correction for the expansion of aqueous vapor
is, in the writer's view, a doubtful improvement. The laws of the distri-
bution and transmission of moisture through the atmosphere are too little
known, and its amount, especially in mountain regions, is too variable, and
depends too much upon local winds and local condensation, to allow a
' ' reasonable hope of obtaining the mean humidity of the layer of air between
' l the two stations by means of hygrometrical observations made at each of
" them. These doubts are confirmed by the experience of the author and
"of many other observers, which shows that, on an average, I^aplace's
" method works not only as well as the other, but more uniformly well. At
" any rate the gain, if there be any, is not clear enough to compensate for
' ' the undesirable complication of the formula. ' '
Since this position was taken by Dr. Guyot forty years ago, there has
been no such advance in our knowledge as to impair the practical conclusion
in conformity with which he constructed his hypsometric table. Accord-
ingly in treating this portion of the formula in the construction of the
present tables for the reduction of the barometer to sea level, it has been
deemed advantageous to retain the method adopted by Guyot, and to
incorporate the humidity factor in the temperature term, thereby assum-
ing the air to contain the average degree of humidity corresponding to the
actually prevailing condition of temperature.
In evaluating the humidity factor as a function of the air temperature,
the tables given by Prof. Ferrel have been adopted {Meteorological researches.

The practical tables consist essentially of two mutually dependent
parts : the first gives values of 2000 m in a table of double entry of
which the altitude of the station and the mean temperature of the air
between the station and sea level are the arguments ; the second gives the
reduction to sea level in a table of double entry of which the arguments
are 2000 m and the observed barometric height corrected for temperature.
In addition, a subsidiary table gives the small correction for latitude to
be applied to the values of 2000 m. This correction, while of theoretical
interest, seldom becomes of practical importance, since its effect is in
general overshadowed by the relatively large uncertainties incident to the
determination of the true mean temperature.
The mean temperature of the air column is to be obtained from the
observed temperature at the station by employing some assumption as to
the rate of change of temperature with altitude. In the discussion of
barometric observations made in the mountain and plateau regions of the
United States, it has been found that this rate of change is a climatic factor
which needs to be determined for every station for different seasons of the
year, and for different atmospheric conditions. When the results of such
investigations are embodied in tables for reduction to sea level, the tables and
the method of their use may be simplified and the labor of obtaining the
reduction greatly abridged ; but in the nature of the case, these special
methods can not be utilized in the construction of general tables which
are to be applicable to all phases of topography and climate.
Whatever method be used for obtaining the mean temperature of the
air column (0) from the observed temperature at the station, the former
and hence the latter is subject to the important condition that it shall not
contain the diurnal fluctuation. Hence in reducing to sea level any indi-
vidual observation of the barometer, the simultaneous observation of air
temperature used in obtaining should be reduced to the daily mean by
a correction, or, better, the actual mean temperature of the preceding twenty-
four hours should be taken.

The temperature varies by intervals of 2 from 20 F. to 96 F.,
except near the extremities of the table where the interval is 4? The alti-
tude Z varies by intervals of 100 feet from 100 to 9000 feet. The values
of 2000 m are given to one decimal.
In order to facilitate interpolations for iractions of a 100 feet in
altitude, the tabular differences for 100 feet have been added on each line.
Table 15 gives a small correction to 2000 m for latitude, computed
from the expression
2000 m x 0.002662 cos 2 <.
The arguments are 2000 m, which varies by tens from 10 to 350, and
the latitude, which varies by 5 from o to 90! The correction is to be
subtracted for latitudes below 45 and added for latitudes above 45. The
tabular values are given to one decimal.
Table 16, with the value of 2000 m thus corrected, gives the correction
which must be applied to the barometric reading B (corrected for tem-
perature) to reduce it to sea level. The arguments are B, which varies by
0.5 inch from 31.00 inches to 19.5 inches, and values of 2000 m y which are
given for every unit from i to 334.
The reduction values B B are given to o.oi inch.
Example :
Let .# = 26.24 inches be the barometric reading (corrected for temper-
ature) observed at a station whose altitude is 3572 feet, and latitude
32 Suppose the mean temperature of the air column = 63^0 F.
Table 14 gives (p. 63) with Z= 3,500 feet and 6 = 62.8 F., 2000 m = 108.0
The difference for 72 feet is 2.2
The approximate value of 2000 m is 110.2
Table 15, with 2000 m = no and latitude = 32, gives the subtractive
correction o.i. Hence the corrected value of 2000 m is no.i.
With 20oom = 110.1 and .# = 26.24, Table 16 (p. 72) gives the reduc-
tion to sea level, 3.55 inches. Accordingly the barometric pressure reduced
to sea level is
B. = 26.24 + 3-55 = 29-79 inches.
XXvi INTRODUCTION.
TABLES 17, 18, 19. Reduction of the barometer to sea level Metric measures.
For reducing to sea level readings of the metric barometer, the baro-
metric formula in metric measures derived on page xxii is treated in the
same manner as the formula in Bnglish measures just described in detail,
and the method of construction of the tables is the same.
Table 17 gives values of 2000 m.
Z i

18444 + 67.53 + 0.003 Z'l
The temperature & varies by intervals of 2 from 16 C. to -f 36 C.
except near the extremities of the table where the interval is 4. The alti-
tude Z varies by 10 metres from 10 to 3000 metres. The values of 2000 m
are given to one decimal.
Table 18 gives the small correction to 2000 m for latitude. The argu-
ments are 200am, which varies by tens from 10 to 350, and the latitude
which varies by 5 from o to 90 The correction is to be subtracted for
latitudes below 45 and added for latitudes above 45. The tabular values
are given to one decimal. The value of 2000 m thus corrected is then used
in entering Table 19.
Table 19 gives the correction which must be applied to the barometric
reading B (corrected for temperature) to reduce it to sea level. The argu-
ments are B, which varies by lomm. from 790 mm. to 480 mm., and values
of 2000 m which vary by units from i to 345. The tabular values B B
are given to o. i mm.
Example :
I/et B= 648.7mm. be the barometric reading observed and corrected
for temperature at a station whose altitude is 1353 metres and latitude
32. Suppose the mean temperature of the air column 0= i4?3 C.
Table 17 gives (p. 83) for = 14 and Z 1353, 2000 m = 138.6
The proportional part for 0^3 is .15
Hence the approximate value of 2000 m is 138.45
Table 18, with 2000 m 138 and latitude 32, gives the subtract! ve
correction 0.15. Hence the corrected value of 2ooom is 138.3. With this
value and B 649 mm. as arguments, Table 19 gives # B = 112.0 mm.
Accordingly the barometric reading reduced to sea level is
B 648.7 + 1 12.0 = 760. 7 mm.

in which A' (log -# log B} is an approximate value of Z and the factors
in the brackets are correction factors depending respectively on the air
temperature, the humidity, the variation of gravity with latitude, the varia-
tion of gravity with altitude in its effect on the weight of mercury in the
barometer, and the variation of gravity with altitude in its effect on the
weight of the air. With the constants already given, the formula becomes
in English measures :
Z (feet) = 60368 (log B - log B)
[i +0.002039(0 32)]
(*+ffl
(l + O.002662 COS 2<) (l + 0.00239)
In order to make the temperature correction as small as possible for
average air temperatures, 50 F. will be taken as the temperature at which
the correction factor is zero. This is accomplished by the following trans-
formation :
i + 0.002039 ( 3 2 ) = C 1 + 0.002039 (0 50)] [i + 0.0010195 x 36].
The second factor of this expresssion combines with the constant, and
gives 60368 (i +0.0010195 x 36) = 62583.6.
The first approximate value of Z is therefore
62583.6 (log B - log B).
In order further to increase the utility of the tables, we shall make a
further substitution for log B log B, and write
- log
62583.6 (log B - log B) = 62583.6 log
Table 2O contains values of the expression
62583.6 log ^
for values of B varying by intervals of o.oi inch from 12.00 inches to 30.90
inches.
The first approximate value of Z is then obtained by subtracting the
tabular value corresponding to B from the tabular value corresponding to
B (B and B being the barometric readings observed and corrected for
temperature at the upper and lower stations respectively).
xxviii INTRODUCTION.
Table 21 gives the temperature correction
Zx 0.002039 (0 50).
The side argument is the mean temperature of the air column (0) given
for intervals of i from o to 100 F. The top argument is the approximate
difference of altitude Z obtained from Table 20.
For temperatures above 50 F. , the correction is to be added, and for
temperatures below 50 F., the correction is to be subtracted. It will be
observed that the correction is a linear function of Z, and hence, for example,
the value for Z 1740 is the sum of the corrections in the columns headed
1000, 700, and 40.
In general, accurate altitudes can not be obtained unless the temperature
used is freed from diurnal variation.
Table 22 gives the correction for latitude, and for the variation of gravity
with altitude in its effect on the weight of the mercury. When altitudes
are determined with aneroid barometers the second factor does not enter the
formula. In this case the effect of the latitude factor can be obtained
by taking the difference between the tabular value for the given latitude and
the tabular value for latitude 45? The side argument is the latitude of the
station given for intervals of 2. The top argument is the approximate
difference of height Z.
Table 23 gives the correction for the average humidity of the air at
different temperatures; the values of the factor (i + ft) adopted by Prof.
Ferrel and given on page xxiii have been used. This correction could have
been incorporated with the temperature factor in Table 21, but it is given
separately in order that the magnitude of the correction may be apparent,
and in order that, when the actual humidity is observed, the correction may
be computed if desired, by the expression
Z (0.378 f
where e is the mean pressure of vapor in the air column, and b the mean
barometric pressure.
The side argument is the mean temperature of the air column, varying
by intervals of 2 from 20 F. to 96 F., except near the extremities of the
table where the interval is 4. The top argument is the approximate
difference of altitude Z.
Table 24 gives the correction for the variation of gravity with altitude
in its effect on the weight of the air. The side argument is the approximate
difference of altitude Z, and the top argument is the elevation of the lower
station h .
The corrections given by Tables 22, 23 and 24 are all additive.

Example :
the barometric pressure observed, and corrected for temperature,
at the upper and lower stations be, respectively, B = 23.61 and
B = 29.97. Let the mean temperature of the air column be 35 F.,
and the latitude 44 16'. To determine the difference of height.

Table 24, with Z= 6300 and k = o, gives + 2
Final difference of height (Z) = 6321
If in this example the barometric readings be observed with aneroid
barometers, the correction to be obtained from Table 22 will be simply the
portion due to the latitude factor, and this will be obtained by subtracting
the tabular value for 45 from that for 44, the top argument being Z 6300.
This gives 16 15 = i.
TABLES 25, 26, 27, 28, 29. Metric Measures.

The approximate value of Z (the difference of height of the upper and
lower station) is given by the factor 18400 (log B log B}. This expression
is computed by means of two entries of a table whose argument is the
barometric pressure. In order that the two entries may result at once in an
approximate value of the elevation of the upper and lower stations, a
transformation is made, which gives the following identity:
18400 (log B - log B) = 18400 (log ^ - log ^?) -

Table 25 gives values of the expression 18400 log-^- for values of B

gives an approximate value of the elevation of the upper station above

value of the elevation of the lower station.
Table 26 gives the temperature correction : 0.00367 C. x Z.
The side argument is the approximate difference of elevation Z and the
top argument is the mean temperature of the air column. The values of Z
vary by intervals of 100 m. from 100 to 4000 metres and the temperature
varies by intervals of i from i C. to 10 C. with additional columns for 20,
30, and 40 C. Attention is called to the fact that the formula is linear
with respect to 0, and hence that the correction, for example, for 27 equals
the correction for 20 plus the correction for 7 When the table is used for
temperatures below o C., the tabular correction must be subtracted from,
instead of added to, the approximate value of Z.
Table 27 (pp. 1 12 and 113) gives the correction for humidity resulting
from the factor 0.378 -r x Z= ft Z.
g
Page 112 gives the value of 0.378-7 multiplied by icooo. The side
argument is the mean pressure of aqueous vapor, e, which serves to repre-
sent the mean state of humidity of the air between the two stations.
e = -J (/+/ ) (/and/ being the vapor pressures observed at the two stations)
has been written at the head of the table, but the value to be assigned to e
is in reality left to the observer, independently of all hypothesis. The top
argument is the mean barometric pressure \(B-\- B^) .
The vapor pressure varies by millimetres from i to 40, and the mean
barometric pressure varies by intervals of 20 mm. from 500 mm. to 760 mm.
The tabular values represent the humidity factor ft or 0.378-7, multiplied by
10000.
Page 113 gives the correction for humidity, with Z and 10000 x 0.378 -?
(derived from page 112) as arguments.
The approximate difference of altitude is given by intervals of 100
metres from 100 to 4000 metres, and the values of icooo/2 vary by intervals
of 25 from 25 to 300. The tabular values are given in tenths of metres to
facilitate and increase the accuracy of interpolation.
Table 28 gives the correction for latitude, and for the variation of
gravity with altitude in its effect on the weight of the mercurial column.
When altitudes are determined with aneroid barometers, the latter factor
does not enter the formula. In this case the effect of the latitude factor
can be obtained by subtracting the tabular value for latitude 45 from the
tabular value for the latitude in question.
The side argument is the approximate difference of elevation Z, varying
by intervals of 100 metres from 100 to 4000. The top argument is the
latitude varying by intervals of 5 from o to 75.

Table 29 gives the correction for the variation of gravity with altitude
in its effect on the weight of the air.
The side argument is the same as in Table 28 ; the top argument is
the height of the lower station varying by intervals of 200 metres from o to
2000, with additional columns for 2500, 3000 and 4000 metres.
Example :

TABLE 30. Difference of height corresponding to a change of o.i inch in
the barometer English measures.
If we differentiate the barometric formula, page xxvii, we shall obtain,
neglecting insensible quantities,
dZ 26281 g- (i + 0.002039 (0 32)) (i+#)-
in which B represents the mean pressure of the air column dZ.
Putting dB o. i inch,
dZ = -j^ (\ +0.002039 (# 32)) (i+/3)
The second member, taken positively, expresses the height of a column
of air in feet corresponding to a tenth of an inch in the barometer on the
parallel of 45 latitude. Since the last factor (i -f /3), as given on page xxiii,
is a function of the temperature, the function has only two variables and
admits of convenient tabulation.
Table 30, containing values of dZ for short intervals of the arguments
B and 0, has been taken from the Report of the U. S. Coast Survey, 1881,
Appendix 10, Barometric hypsometry and reduction of the barometer to sea
level, by Wm. Ferrel.*

Ferrel's formula, upon which the table is computed, is

XXXii INTRODUCTION.
The temperature argument is given for every 5 from 30 F. to 85 F.,
and the pressure argument for every 0.2 inch from 22.0 to 30.8 inches.
This table may be used in computing small differences of altitude, and,
up to a thousand feet or more, very approximate results may be obtained.
Example :
Mean pressure at Augusta, October, 1891, 29.94 ; temperature, 6o.8 F.
Mean pressure at Atlanta, October, 1891, 28.97 J temperature, 59.4
Mean pressure of air column, .# = 29.455; # = 6o.i
Entering the table with 29.455 an( i 6oi as arguments, we take out 94.95
as the difference of elevation corresponding to a tenth of an inch difference
of pressure. Multiplying this value by the number of tenths of inches
difference in the observed pressures, viz. 97, we obtain the difference of
elevation 921 feet.
TABLE 31. Difference of height of air corresponding to a change of i
millimetre in the barometer Metric measures.
This table has been computed by converting Table 18 into metric units.
The temperature argument is given for every 2 from 2 C. to + 36 C. ; the
pressure argument is given for every millimetre from 760 to 560 mm.
TABLE 32. Babinet "s formula for determining heights by the barometer.
Babinet's formula for computing differences of altitude* represents the
formula of L,aplace quite accurately for differences of altitude up to 1000
metres, and within one per cent for much greater altitudes. As it has been
quite widely disseminated among travellers and engineers, and is of con-
venient application, the formula is here given in English and metric measures.
It might seem desirable to alter the figures given by Babinet so as to con-
form to the newer values of the barometrical constants now adopted ; but
this change would increase the resulting altitudes by less than one-half of
one per cent without enhancing their reliability to a corresponding degree,
on account of the outstanding uncertainty of the assumed mean temperature
of the air.
The formula is, in English measures,
Z (feet) = 5*494
and in metric measures,
in which Z is the difference of elevation between a lower and upper station
at which the barometric pressures corrected for all sources of instrumental
error are B and B, and the observed air temperatures are / and t, respectively.
* Comptes Rendus, Paris, 1850, vol. xxv., page 309.
BAROMETRICAL TABLES. XXxiii
For ready computation the formula is written
Z=Cx|^|,
and the factor C, computed both in English and metric measures, has been
kindly furnished by Prof. Cleveland Abbe. The argument is -J (t + /)
given for every 5 Fahrenheit between 10 and 100 F., and for every 2
Centigrade between 10 and 40 Centigrade.
In using the table, it should be borne in mind that on account of the
uncertainty in the assumed temperature, the last two figures in the value of
C are uncertain, and are here given only for the sake of convenience of
interpolation. Consequently one should not attach to the resulting altitudes
a greater degree of confidence than is warranted by the accuracy of the
temperatures and the formula. The table shows that the numerical factor
changes by about one per cent of its value for every change of five degrees
Fahrenheit in the mean temperature of the stratum of air between the
upper and lower stations ; therefore the computed difference of altitude will
have an uncertainty of one per cent if the assumed temperature of the air
is in doubt by 5 F. With these precautions the observer may properly
estimate the reliability of his altitudes whether computed by Babinet's
formula or by more elaborate tables.
Example :
Let the barometric pressure observed and corrected for temperature at
the upper and lower stations be, respectively, B = 635 mm. and
BO 730 mm. Let the temperatures be, respectively, ^=15 C,
to 20 C. To find the approximate difference of height.
With i (/ + f] = i7?5 C., the table in metric measures gives
C= 17120 metres.
-

The approximate difference of height = 17120 x -*~- = 1191.5 metres.
THERMOMETRICAI, MEASUREMENT OF HEIGHTS BY OBSERVATION OF THE
TEMPERATURE OF THE BOILING POINT OF WATER.
When water is heated in the open air, the elastic force of its vapor
gradually increases, until it becomes equal to the incumbent weight of the
atmosphere. Then, the pressure of the atmosphere being overcome, the
steam escapes rapidly in large bubbles and the water boils. The tem-
perature at which water boils in the open air thus depends upon the
weight of the atmospheric column above it, and under a less barometric
pressure the water will boil at a lower temperature than under a greater
pressure. Now, as the weight of the atmosphere decreases with the
elevation, it is obvious that, in ascending a mountain, the higher the
XXXIV INTRODUCTION.
station where an observation is made, the lower will be the temperature of
the boiling point.
The difference of elevation between two places therefore can be deduced
from the temperature of boiling water observed at each station. It is
only necessary to find the barometric pressures which correspond to those
temperatures, and, the atmospheric pressures at both places being known,
to compute the difference of height by the tables given herein for com-
puting heights from barometric observations.
From the above, it may be seen that the heights determined by
means of the temperature of boiling water are less reliable than those
deduced from barometric observations. Both derive the difference of alti-
tude from the difference of atmospheric pressure. But the temperature of
boiling water gives only indirectly the atmospheric pressure, which is
given directly by the barometer. This method is thus liable to all the
chances of error which may affect the measurements by means of the
barometer, besides adding to them new ones peculiar to itself, the prin-
cipal of which is the difficulty of ascertaining with the necessary accuracy
the true temperature of boiling water. In the present state of ther-
mometry it would hardly be safe, indeed, to rely, in the most favorable
circumstances, upon quantities so small as hundredths of a degree, even
when the thermometer has been constructed with the utmost care ; more-
over, the quality of the glass of the instrument, the form and substance
of the vessel containing the water, the purity of the water itself, the position
at which the bulb of the thermometer is placed, whether in the current of
the steam or in the water, all these circumstances cause no inconsiderable
variations to take place in the indications of thermometers observed under
the same atmospheric pressure. Owing to these various causes, an obser-
vation of the boiling point, differing by one-tenth of a degree from the true
temperature, ought to be still admitted as a good one. Now, as the tables
show, an error of one- tenth of a degree Centigrade in the temperature of
boiling water would cause an error of 2 millimetres in the barometric
pressure, or of from 70 to 80 feet in the final result, while with a good
barometer the error of pressure will hardly ever exceed one-tenth of a
millimetre, making a difference of 3 feet in altitude.
Notwithstanding these imperfections, the hypsometric thermometer is
of the greatest utility to travellers and explorers in rough countries, on
account of its being more conveniently transported and much less liable
to accidents than the mercurial barometer. A suitable form for it, designed
by Regnault (Annales de Chimie et de Physique, Tome xiv, p. 202), consists
of an accurate thermometer with long degrees, subdivided into tenths.
For observation the bulb is placed, about 2 or 3 centimetres above the
surface of the water, in the steam arising from distilled water in a cylin-
drical vessel, the water being made to boil by a spirit-lamp.

PRESSURE OP AQUEOUS VAPOR IN SATURATED AIR.
Tables 35, 36, and 43, giving the pressure of aqueous vapor in saturated
air, are based upon Dr. Broch' s reduction of the observations of Regnault
{Travaux et Memoires du Bureau international des Poids et Mesures, t. I,
p. A 19-39). This reduction assumes that the observations may be repre-
sented by the empirical formula
in which F is the pressure of aqueous vapor expressed in millimetres of
standard mercury, that is at o C. and at latitude 45 and sea
level, its density being 15.59593.
t, the temperature expressed in normal Centigrade degrees.
= 0.003667458
By using the simultaneous values of F and t given by Regnault's
observations, Dr. Broch obtained a series of observation equations whose
solution by the method of least squares gave the following values for the
coefficients :
A= 4.5686859

From this formula Broch' s tables of vapor pressure were computed.
XXXVI INTRODUCTION.
TABLE 35. Pressure of aqueous vapor English measures.
This table is a conversion into English measures of Table 36. It gives
the vapor pressure in saturated air for temperatures varying by o?2 from
20.o to 2i4o Fahrenheit.
The tabular values are given in inches to four decimals.
A column of differences for o.i is added for convenience in interpolating.
TABLES 36, 43. Pressure of aqueous vapor, Metric measures.
These tables, taken from Broch, give the pressure of aqueous vapor to
hundredths of a millimetre for temperatures varying by o.i C. from 29^0
to 100^9 Centigrade. The values for temperatures between o C. and 45 C.
are given in Table 43, the remainder in Table 36.
TABLE 37. Pressure of aqueous vapor at low temperature. (C. F. Marvin.']
Broch's vapor pressures at temperatures below o C. (32 F.} as given in
Tables 35 and 36, when compared with the actual observed values of Reg-
nault are found to be systematically too large. This discrepancy signifies
that the empirical formula adopted by Broch fails to represent accurately
the law of variation of vapor pressure for temperatures both above and
below the freezing point. Moreover, the failure in the application of the
formula might be inferred from the laws of diffusion following from the
kinetic theory of gases, for these give no reason to suppose that the function
expressing the relation between vapor pressure and temperature is continuous
between the two states of water and ice.
Under proper conditions water can be cooled far below o C. (32 F.}
before solidifying, so that at the same temperature we may have it either
in the liquid or the solid state, and experiments confirm the theory of
diffusion in showing that the pressure of the vapor is different according as
it is in contact with its liquid or its solid at the same temperature. The
method hitherto employed of combining vapor pressures above and below
freezing, and attempting to represent them by a single continuous function,
must therefore be considered as radically erroneous.
Recognizing the systematic errors of the vapor pressures given by
Broch's formula for temperature below freezing, the Chief Signal Ofiicei
lately authorized a new determination by direct observation. This experi-
mental investigation has been carried out by Prof. C. F. Marvin, from the
results of which (Annual Report Chief Signal Officer, 1891; Appendix No.
10,) Table 37 is reproduced. The interpolation between the observed press-
ures which were noted at intervals of about 5 F., was effected graphically
and not by mathematical formula.
The vapor pressures were determined for the case of the vapor in con-
tact with ice and not a water surface. For the temperature of melting ice
(o C. or 32 F.) all values agree. Below this temperature Marvin's vapor
pressures are slightly smaller than Regnault's, but differ from the latter less
than any other tabular values.

REDUCTION OF OBSERVATIONS WITH THE PSYCHROMETER AND
DETERMINATION OF RELATIVE HUMIDITY.
The psychrometric formula derived by Maxwell, Stefan, August,
Regnault and others is, in its simplest form,
f=f t -AB (/-/,),
in which / Air temperature.
/, = Temperature of the wet-bulb thermometer.
/= Pressure of aqueous vapor in the air.
yj Pressure of aqueous vapor in saturated air at temperature t r
B = Barometric pressure.
A = A quantity which, for the same instrument and for certain
conditions, is a constant, or a function depending in a
small measure on ^ .
The important advance made since the time of Regnault consists in
recognizing that the value of A differs materially according to whether the
wet-bulb is in quiet or moving air. This was experimentally demonstrated
by the distinguished Italian physicist, Belli, in 1830, and was well known
to Espy, who always u.sed a whirled psychrometer. The latter describes
his practice as follows : ' ' When experimenting to ascertain the dew-point
by means of the wet-bulb, I always swung both thermometers moderately
in the air, having first ascertained that a moderate movement produced
the same depression as a rapid one."
The principles and methods of these two pioneers in accurate psychrom-
etry have now come to be adopted in the standard practice of meteor-
ologists, and psychrometric tables are adapted to the use of a whirled or
ventilated instrument.
The factor A depends in theory upon the size and shape of the ther-
mometer bulb, largeness of stem and velocity of ventilation, and different
formulae and tables would accordingly be required for different instruments.
But by using a ventilating velocity of three metres or more per second, the
differences in the results given by different instruments vanish, and the same
tables can be adapted to any kind of a thermometer and to all changes of
velocity above that which gives sensibly the greatest depression of the wet-
bulb temperature; and with this arrangement there is no necessity to
measure or estimate the velocity in each case further than to be certain that
it does not fall below the assigned limit.
*The table has been computed with the factor 11.7449-, which results from Clarke's
value for the conversion of the metre, instead of with the value 11.7459 above derived.
HYGROMETRICAI, TABLES. Xxxix
The formula and tables here given for obtaining the vapor pressure and
dew-point from observations of the whirled or ventilated psychrometer are
those deduced by Prof. Wm. Ferrel {Annual Report Chief Signal Officer,
1886, Appendix 24) from a discussion of a large number of observations.
Taking the psychrometric formula in metric units, pressures being
expressed in millimetres and temperatures in Centigrade degrees, Prof.
Ferrel derived for A the value
A = 0.000656 (i + 0.0019 O
In this expression for A, the factor depending on /, arises from a similar
term in the expression for the latent heat of water, and the theoretical value
of the coefficient of /, is 0.00115. Since it would require a very small
change in the method of observing to cause the difference between the
theoretical value and that obtained from the experiments, Prof. Ferrel
adopted the theoretical coefficient 0.00115 and then recomputed the obser-
vations, obtaining therefrom the final value
A = 0.000660 (i + o.ooi 15/0.
With this value the psychrometric formula in metric measures becomes
f=fi o.ooo66o.# (t t^) (i + O.OOH5/,)
In order to adapt the formula to convenient tabulation, Prof. Ferrel
substituted t t^ for /, in the last factor, a modification which produces
appreciable error only in extreme cases. The error in the computed vapor
pressure will be
^ = 0.00000076 #(*/,) (/ 2/,)-
Expressed in Knglish measures, the formula is
/=/i- 0.000367 B (/-/O [i +0.00064 (/ I - 3 2)]
and with the same modification in order to render the formula more con-
venient for tabulation, we have
/=/ -0.000367^ (t- /,) (i + 0.00064 (/- /,)),

xl INTRODUCTION.
Table 40, with the wet-bulb temperature ^ as an argument, gives the
value of / , the first term of the formula for the vapor pressure / given
above. It is simply an abbreviation of Table 35 for temperatures above
32 F., and of Table 37 for temperatures below 32 F., reprinted for
convenience.
Table 41, with t /, and B as arguments, gives the value of the second
term of the formula, viz :
0.000367 *.(/-
The top argument is given for every half inch from 30.5 to 18.5 inches;
the side argument, t /,, is given for every whole degree up to 40 F.
Tabular values are given to thousandths of inches.
With the two tables we then have,
f (vapor pressure) = Table 40 Table 41 .
The value of / in Table 40, corresponding to the vapor pressure thus
obtained, is the dew-point.
Examples :
1. Given / = 84! > 3; ^ = 667, and B = 30.00 inches, to find the vapor
pressure and dew-point.
Table 40, with ^ 66^7, gives / = 0.654 inches.
Table 41, with t ^ = 84$ 66.y = i76 and B 30.00 inches
as arguments, gives 0.196 inch as the value of the last term
of the expression above. Hence we have the vapor pressure
/ = 0.654 0.196 = 0.458 inch. The temperature (Table 40)
corresponding to this value of/ is the dew-point, d 56^6 F.
2. Given t = ^^\ /, = 29^4, and #-=-22.3 inches, to find the vapor
pressure and dew-point.
Table 40, with /, = 29^4, gives/, = o. 162 inch.
Table 41, with / /, 34^5 29^4 = 5^1 and B= 22.5 inches (the
nearest value in the table to 22.3 inches) as arguments, gives 0.042
inch as the value of the second term of the expression for/. Hence
we have the vapor pressure/ = o. 162 0.042 = o. 120 inch.
The temperature in Table 40, corresponding to this value of/ is the
dew-point, d=22o.
NOTE In using Table 40, the proportional part for tenths of the argument, t /,,
may be easily obtained by taking one-tenth of the tabular value belonging to the same
number of degrees ; for instance, in the first example, the tabular value for 17 is 0.189,
and the proportional part for o?6 is one-tenth the tabular value for 6?o, viz., one-tenth
of .066, or .007. Hence we get o. 189 -f 0.007 = - J 96.

f and F are the maximum pressures of vapor corresponding respectively to

The top argument is / d, extending by half degree intervals from o to

The side argument is the air temperature /, given for intervals of four
degrees from 32 to 120 F.
Example :
L,et the air temperature be 62 F. and the dew-point 51 /*"., to find the

With t d = 1 1 for the top argument, and t = 62 for the side argument,
the table gives 67.5 per cent as the relative humidity.

It gives the vapor pressure to hundredths of a millimetre from 30^0 C.

temperatures above o C.
Table 44, with the depression of the wet-bulb / /,, and the barometric

The top argument is given for every 10 millimetres from 770 to 460 mrn, ;

obtained, is the dew-point.

Given t= io.4 C. ; ^ = 8?3 C. and B = 740 mm. , to find the vapor pressure
and dew-point.
Table 43, with the argument /, = 8.3 C, gives/, = 8. 15 mm.
Table 44, with t t^= 2.i and B 740 as arguments, gives 1.03 mm. as
the value of the last term of the expression for/. Hence we have the vapor
pressure, /= 8.15 1.03 = 7. 12 mm. The value of the temperature in Table
40, corresponding to this vapor pressure, is the dew-point d = 6.3 C.
TABLE 45. Relative humidity Temperature Centigrade.
Table 45 gives the relative humidity of the air in hundredths, having
given the air temperature t and the dew-point d in Centigrade degrees.
It is computed by the formula
Relative humidity = ~,
r
f and F being the maximum pressures of aqueous vapor corresponding to
the temperatures d and t as given in Tables 36 and 43.
The top argument is the dew-point d, extending by 5 intervals from
- 15 to 30 C.
The side argument is the depression of the dew-point t d, given for
every o.2 C. from oo to ioo ; for every o.5 from ioo to 20^0, and for every
i from 2oo to 3O.o.
Example :
Given the air temperature 21" C. and the dew-point 17 C, to determine
the relative humidity.
With / d = 4 C. for the side argument, and d 17 C. for the top
argument, the table gives 78 per cent as the relative humidity.
TABLE 46. REDUCTION OF SNOWFAU, MEASUREMENT.
The determination of the water equivalent of snowfall has usually been
made by one of two methods : (a) by dividing the depth of snow by an
arbitrary factor ranging from 8 to 16 for snow of different degrees of com-
pactness ; () by melting the snow and measuring the depth of the
resulting water. The first of these methods has always been recognized as
incapable of giving reliable results, and the second, although much more
accurate, is still open to objection. After extended experience in the
trial of both these methods, it has been found that the most accurate and
most convenient measurement is that of weighing the collected snow,
and then converting the weight into depth in inches. The method is
equally applicable whether the snow as it falls is caught in the gage, or a
section of the fallen snow is taken by collecting it in an inverted gage.

TABLE 46.
TABLE 46. Depth of water corresponding to the weight of snow (or rain)
collected in an 8-inch gage.
The table gives the depth to hundredths of an inch, corresponding to
the weight of snow or rain collected in a gage having a circular collecting
mouth 8 inches in diameter this being the standard size of gage used
throughout the United States.
The argument is given in avoirdupois pounds, ounces and quarter
ounces in order that it shall be adapted to the customary graduation of
commercial scales.
Example :
The weight of snow collected in an 8-inch gage is 2 Ibs. 2^ oz. To
find the corresponding depth of water.
The table gives directly 1.18 inches.
TABLE 47.
TABLE 47. Rate of decrease of vapor pressure with altitude.
From hygrometric observations made at various mountain stations on
the Himalayas, Mount Ararat, Teneriffe, the Alps, and also in balloon
ascensions, Dr. J. Hann (Zeitschrift fur Meteorologie, vol. ix, 1874, p. 193-200)
has deduced the following empirical formula showing the average relation
between the vapor pressure f at a lower station and/ the vapor pressure at
an altitude h metres above it :
/ -
-~p- I0 6 5 T 7'

This is of course an average relation for all times and places from which
the actual rate of decrease of vapor pressure in any individual case may
widely differ.
Table 47 gives the values of the ratio -y- for values of h from 200 to
6000 metres. An additional column gives the equivalent values of h in feet.

CALCULATION OF THE MEAN DIRECTION OF THE WIND BY LAMBERT'S
FORMULA.
Lambert's formula for the eight principal points of the compass is
E - W + (NE+SE-NW- SW} cos 45
N-S+(NE + NWSE SW)co&4$ 9 '
a is the angle of the resultant wind direction with the meridian.
E, NE, N, etc. , represent the wind movement from the corresponding
directions Kast, Northeast, North, etc. In practice instead of taking the total
wind movement, it is often considered sufficient to take as proportional
xliv INTRODUCTION.
thereto the number of times the wind has blown from each direction, which
is equivalent to considering the wind to have the same mean velocity for all
directions.
If directions are observed to sixteen points, half the number belonging
to each extra point, should be added to the two octant points between
which it lies ; for example, NNE = 6 should be separated into N= 3 and
NE = 3 ; ESE = 4 into E 2 and SE 2 . The result will be approximately
identical with that obtained by using the complete formula for sixteen points.
TABLE 48. Multiples of cos 45 ; form for computing the numerator and
denominator.
TABLE 49. Values of the mean direction (a) or its complement (90 a).
Table 48 gives products of cos 45 by numbers up to 209, together with
a form for the computation of the numerator and denominator, illustrated
by an example. The quadrant in which a lies is determined by the follow-
ing rule :
When the numerator and denominator are positive, a lies between
A^ and E.
When the numerator is positive and the denominator negative, a lies
between S and E.
When the numerator and denominator are negative, a lies between
5 and W.
When the numerator is negative and the denominator positive, a lies
between A^ and IV.
Table 49 * combines the use of a division table and a table of natural
tangents. It enables the computer, with the numerator and denominator of
Lambert's formula (computed from Table 48) as arguments, to take out
directly the mean wind direction a or its complement.
The top argument consists of every fifth number from 10 to 200.
The side argument is given for every unit from i to 50 and for every two
units from 50 to 150. Tabular values are given to the nearest whole degree.
Rule for using the table :
Enter the table with the larger number (either numerator or denomi-
nator) as the top argument.
If the denominator be larger than the numerator, the table gives a.
If the denominator be smaller than the numerator, the table gives
90 a.
a is measured from the meridian in the quadrant determined by the rule
given with Table 48.

NOTE. If the numerator and denominator both exceed 150 or if either exceeds
200, the fraction must be divided by some number which will bring them within the
limits of the table. The larger the values, provided they are within these limits, the
easier and more accurate will be the computation. For example, let tan a = ! .

TABLE 57. Beaufort wind scale and its conversion into velocity.
The personal observation of the estimated force of the wind on an
arbitrary scale is a method that belongs to the simplest meteorological
records and is widely practiced. Although anemometers are used at meteor-
ological observatories^ the majority of observers are still dependent upon
estimates based largely upon their own judgment, and so reliable can such
estimates be made that for many purposes they abundantly answer the
needs of meteorology as well as of climatology.
A great variety of such arbitrary scales have been adopted by different
observers, but the one that has come into the most general use and received
the greatest definiteness of application is the duodecimal scale introduced
into the British navy by Admiral Beaufort about 1800.
The definitions of the successive grades of the Beaufort scale were
made in terms of the effect of the wind on the sails of a full-rigged ship, so
that navigators of all nations have generally acquired a very uniform and
definite idea of their meaning and a very considerable expertness in the use
of the scale. The Table gives the designations of the 1 2 grades together
with several conversions of the scale into wind velocities as made by
different meteorologists. A committee appointed by the Royal Meteoro-
logical Society to establish a conversion of the Beaufort scale into wind
velocity made a preliminary report (Quart. Journal Roy. Meteorological Soc. ,
vol. 13, 1887), but did not consider their work sufficiently complete to present
a definite conversion table, f

LENGTH OF A DEGREE OF THE MERIDIAN AND OF ANY PARALLEL.
The dimensions of the earth used in computing lengths of the meridian
and of parallels of latitude are those of Clarke's spheroid of 1866.* This
spheroid undoubtedly represents very closely the true size and shape of the
earth, and is the one to which nearly all geodetic work in the United States
is now referred.
The values of the constants are as follows :
a, semi-major axis = 20926062 feet ; log a = 7.3206875.
d, semi-minor axis = 20855121 feet ; log = 7.3192127.
a 2 b*
<? 2 = = 0.00676866; log <? 2 = 7.8305030 10.
With these values for the figure of the earth, the formula for computing
any portion of a quadrant of the meridian is
Meridional distance in feet= [5. 561828 4] A < (in degrees),
[5.0269880] cos 2$ sin A <,
-f [2.0528] cos 4$ sin 2 A <,
in which 2<j> = <f> 2 -f- ^ , A< = < 2 ~~ <i > 0i > < 2 = en d latitudes of arc.
For the length of i degree, the formula becomes :
i degree of the meridian, in feet = 364609.9 1857.1 cos 2< -f 3.94 cos 4<.
The length of the parallel is given by the equation
i degree of the parallel at latitude <, in feet =
3 6 553 8 -4 8 cos < 310.17 cos 3^ + 0.39 cos 5<.
TABLE 59.
TABLE 59. Length of one degree of the meridian at different latitudes.
This gives for every degree of latitude the length of one degree of the
meridian in statute miles to three decimals, in metres to one decimal, and
in geographic miles to three decimals the geographic mile being here
defined to be one minute of arc on the equator. The values in metres are
computed from the relation : i metre = 39.3700 inches. The tabular values
represent the length of an arc of one degree, the middle of which is
situated at the corresponding latitude. For example, the length of an arc
of one degree of the meridian, whose end latitudes are 29 30' and 30 30^ is
68.879 statute miles.

Table 61 has been computed for this volume by Prof. Wm. L,ibbey, jr.
It is a table of double entry with arguments 8 and <. For north latitudes
northerly declination is considered positive and southerly declination as
negative. The table may be used for south latitudes by considering
southerly declination as positive and northerly declination as negative.
The top argument is the latitude, given for every 5 from o to 40, for
every 2 from 40 to 60, and for every degree from 60 to 8o.
The side argument is the sun's declination for every 20' from 6" 23 2 7'
to N 23 27'.
The duration of sunshine is given in hours and minutes.
To find the duration of sunshine for a given day at a place whose
latitude is known, find the declination of the sun at mean noon for that day
in the Nautical Almanac, and enter the table with the latitude and declination
as arguments.

TABLE 62. Declination of the sun for the year 1894.
This table is an auxiliary to Table 61, and gives the decimation of the
sun for every third day of the year 1894. These declinations may be used
as approximate values for the corresponding dates of other years when the
exact declination can not readily be obtained. Thus, in the preceding
example, the declination for May 18 may be taken as approximately the
same as that for the same date in 1894, viz. 19 37'.

TABLE 65. Millimetres into inches.
From o to 400 mm. the argument is given to every millimetre, with
subsidiary interpolation tables for tenths and hundredths of a millimetre.
The tabular values are given to four decimals. From 400 to 1000 mm.,
covering the numerical values which are of frequent use in meteorology
for the conversion of barometric readings from the metric to the English
barometer, the argument is given for every tenth of a millimetre, and the
tabular values to three decimals.
Example :
To convert 143.34 mm - to inches.
The table gives

Table 66 gives the value in metres and thousandths (or millimetres)
for every foot from o to 99 feet ; the value to hundredths of a metre (or
centimetres) of every 10 feet from 100 to 4000 feet ; and the value to tenths
of a metre of every 10 feet from 4000 to 9090 feet. In using the latter
part, the first line of the table serves to interpolate for single feet.
Example :
To convert 47 feet 7 inches to metres. 47 feet 7 inches =47.583 feet.

is computed from the fraction - - . The corresponding value in angle
obtained by multiplying this fraction by 360, is given to the nearest minute.
Two additional columns serve to enter the table with the day of the
month either of the common or the bissextile year as the argument, and
may be used also for converting the day of the month to the day of the
year, and vice versa.
Example :
To find the number of days and the decimal of a year between February

December 15, 1891.
The table gives for December 16, n h 56. By interpolating, it is seen
that the change to December 15 would be less than one-half minute ;
the correct clock time is therefore 4 minutes before 12 o'clock noon.

In English measures, the formula becomes
g = 0.00129305 / 0.378 e\
~ i x 0.0020389 (/ 32) \ 29.921 /
where 8 is denned as before, but b and e are expressed in inches and t in
Fahrenheit degrees. Thus by the use of tables based on these two formulae,
lines of equal atmospheric density may be drawn for the whole world
(neglecting slight variations in gravity), whether the original observations
are in English or metric measures. Prof. Cleveland Abbe has kindly fur-
nished for the present volume the logarithms of the density given in the
accompanying tables (81 to 86).

Table 85 gives values of 0.378^ to hundredths of a millimetre for dew-
points extending by intervals of i from 30 C. to 50 C. The values of
Broch's vapor pressures (e) corresponding to these dew-points are given in a
second column to hundredths of a millimetre. The table is thus conveniently
used when either the vapor pressure or the dew-point is known.
Table 86 gives values and logarithms of - - ~- for values of

obtained from Table 85. The logarithms are given to five significant figures
and the corresponding numbers to four decimal places.
TABLE 87. Conversion of avoirdupois pounds and ounces into kilogrammes.
The latest comparisons made by the International Bureau of Weights
and Measures between the Imperial standard pound and the "kilogramme
proto-type ' ' result in the relation :
i pound avoirdupois 453.592 427 7 grammes.
This value has been adopted by the United States Bureau of Weights
and Measures and is here used.
For the conversion of pounds, Table 87 gives the argument for
every tenth of a pound up to 9.9, and the tabular conversion values to
ten-thousandths of a kilogramme.
For the conversion of ounces, the argument is given for every tenth of
an ounce up to 15.9, and the tabular values to ten- thousandths of a kilo-
gramme.
TA B LE 88. Conversion of kilogrammes into avoirdupois pounds and ounces.
From the above relation between the pound and the kilogramme,
i kilogramme = 2.204622 avoirdupois pounds.
= 35.274 avoirdupois ounces.
MISCELLANEOUS TABLES. Ivil
The table gives the value to thousandths of a pound of every tenth of
a kilogramme up to 9.9 ; the values of tenths of kilogrammes in ounces to
four decimals ; and the values of hundredths of a kilogramme in pounds and
ounces to three and two decimals respectively.
TABLES 89, 90.
TABLE 89. Conversion of grains into grammes.
TABLE 90. Conversion of grammes into grains.
From the above relation between the pound and the kilogramme,
i gramme = 15.432356 grains.
i grain = 0.06479892 gramme.
Table 89 gives to ten-thousandths of a gramme the value of every
grain from i to 99, and also the conversion of tenths and hundredths of a
grain for convenience in interpolating.
Table 90 gives to hundredths of a grain the value of every tenth of a
gramme from o. i to 9.9, and the value of every gramme from i to 99. The
values of hundredths and thousandths of a gramme are added as an aid to
interpolation.
The computation of these two tables has been furnished by Professor
William L,ibbey, who has used the relation, i gramme = 15.432 531 grains.
This value is practically identical with the relation above adopted, differing
from it by about i part in 3,000,000.
TABLE 91
TABLE 91. Conversion of units of magnetic intensity.
This table gives the conversion factors from i to 9 for converting
Hsh measures of magnetic intensity into C. G. S. measures, and vice versa.
The English unit of magnetic intensity is the force which, acting for
i second on a unit of magnetism associated with a mass of i grain, produces
a velocity of i foot per second.
The C. G. S. unit of magnetic intensity is the dyne the force which,
acting upon one gramme for i second, generates a velocity of i centimetre
per second. The Gaussian unit of magnetic intensity, which has been
extensively used, is a force which, acting upon a mass of i milligramme for
i second, generates a velocity of i millimetre per second.
By using the dimensions of magnetic intensity [M^/I^T], the inter-
conversion of these units is easily made.

TABLE 93. Dates of Dove^s pentades.
For tabulating and averaging meteorological data, Dove divided the
year into seventy-three intervals of five days each, which have been called
Dove's pentades, and this system of averaging has been used in the
publication of a very considerable amount of meteorological data. Table
93 gives the initial and terminal dates of each pentade throughout the year.
TABLE 94. Division by 28 of numbers from 28 to 867972.
TABLE 95. Division by 29 of numbers from 29 to 898971.
TABLE 96. Division by 31 of numbers from 31 to 960969.
The frequent occasion in meteorological work to divide by the numbers
28, 29 and 31 renders useful the division tables compiled by Mr. H. A.
Hazen {Handbook of Meteorological Tables, Washington, D. C., 1888), the
use of which has been kindly granted.
As here printed, the dividend is given in plain type and the quotient in
heavy-face type, and in order that one shall never be mistaken for the other, a
column is given containing the letters D and Q successively, which
designates that all figures on a line with D are dividends, and all on
a line with Q are quotients. The four columns to the right of this D-Q
column give the last two figures of the dividend and of the quotient,
namely, the units and tens. The ten columns to the left side of the
D-Q column give the preceeding figures of the dividend, namely, the
hundreds, thousands, and tens of thousands. These two parts of the
dividend to the left and right of the D-Q column are always to be taken
on the same horizontal line.
Each dividend is an exact multiple of the divisor, hence each quotient
is exact or without remainder.
For example, the dividend 17360 in Table 94 is found in two parts ;
173 is found in the column headed 600 on the left-hand side of the D-Q
column, and 60 in the same horizontal row in the third column on the right-
hand side.
The hundreds figure of the quotient is given in bold-face type at the
top, middle and bottom of the page, and each one obtains for all the dividend
figures in its own column. The units and tens figures of the quotient are
found, as already stated, on the right side of the D-Q column directly under
the last two figures of the dividend. Thus in the above example, for dividend
17360 the hundreds figure of the quotient is 6 and the units and tens will be
20, or the quotient of 17360 divided by 28 is 620. When any given dividend
MISCELLANEOUS TABLES. lix
is not an exact multiple of the divisor, the nearest even multiple as given in
the table must be used.
For example, 23979 -5- 28 = 856 ; the 8 is in the 9th column above 239
and the 56 is under 68, the nearest figure to 79 in the right-hand part of
the table.
The last column, which is separated from the rest of the table by a
triple line, is to be used when the quotient exceeds three figures, or 999.
The bold-face figures in this column give the thousands and tens of
thousands figures of the quotient, and the plain figures are the multiples
thereof by the divisor. To use the column, find in it the number which,
with three ciphers added, comes nearest to (but is less than) the dividend ;
the heavy-face figures beneath it will be the first figures of the quotient.
Subtract this multiple number from the given dividend, and with the
remainder enter the main body of the table to obtain the last three figures
of the quotient as already described.
For example : Divide 833885 by 28. The nearest figure to 833000 in the
last column is 812000 and the quotient 29000. 833885 812000 = 21885.
Under 218 we have 7, and under 96, the nearest figure to 85 on the right,
we find 82. 833885-^-28 = 29782.

TABLE 100. List of meteorological stations.
This list of meteorological stations has been compiled for this volume
from data furnished by the United States Weather Bureau.
A geographical arrangement has been adopted as being most serviceable
for the purposes for which the table will most generally be used.
In making the selection of stations from the vast number available, the
object has been to choose such of the higher order stations as will fairly
represent the varied climatic conditions of each country. With few excep-
tions, the stations are active ; in all cases there are published observations,
which may generally be found in the monthly and annual reports of the
national meteorological services of the countries in which the stations are
situated, or by which they are politically controlled.
So far as known, the list contains all first order stations, i. <?., those at
which the principal meteorological elements are either recorded continuously
and automatically, or are observed at hourly or bi-hourly intervals ; such
stations are designated by an asterisk (*).
The names of the stations have been given in the native orthography,
which is in all cases the form adopted by the national meteorological service
hi its official publications.

a is the angle between the mean wind direction and the meridian.
The signs of the numerator (n) and denominator (d) determine the quadrant in which a lies.
When n and d are positive, a lies between N and E : - = NE.
When n is positive and d negative, a lies between S and E : ~ = SE.
When n and d are negative, a lies between S and W : - = SW.
When n is negative and d positive, a lies between N and W : J = NW.
