Tux Navtican Aumanac and AstroxomicaL Ermemunis for the year 1838 has 
deen constructed upon the same plan as those of the preceding years, commencing 
with the year 1834, 

‘Tne Sun’s Longitude from the Mean Equinox, the Latitude, and the Earth’s Radius 
Vector have been deduced from the New Tubles appended to Kffemeridi Astronomiche 
di Mitano per U Anno 1833, (Milano, 1832), using a difference of Meridians =36" 45". 

‘The Perturbations of Longitude and Radius Vector produced by each of the Planets, 
Venus, Mars, Jupiter, and Saturn, have been computed accurately from the Tables for 
every 10th day of the year; the Sums then interpolated with second differences for 
every 5th day and thence the daily perturbations by simple proportion. The other 
parts of the calculations have been performed independently for every Mean Noon. 

The Latitude of the Sun, depending on the attractions of the Moon, was computed 
for every day, and that depending upon each of the Planets, Venus and Jupiter, was 
obtuined for each tenth day and interpolated. 

‘The Nutations of the Obliquity of the Ecliptic (A) and of Longitude (4 L), have 
been derived from MS, Tables constructed according to the following formule :

For Mars, the Heliocentric Longitude from the Mean Equinox, Latitude and 
Radius Vector were obtained independently for every twelfth day, and interpolated 
with fourth differences for each day, previously to the application of Nutation. The - 
Geocentric places were computed’ for every fourth day, and interpolated with fourth 
differences, 

For Jupiter, Sater, adit the Gagan, che Hfliocentrls Lone fers Bt Seon 
Equinox, Latitude and Railius Vector were computed direetly from the Tables at 
intervals of thirty days; and interpolated, for each day, with second differences, pre- 
viously to the application of Nutation. The Geocentrie places were obtained inde- 
pendently for every sixth day, and interpolated for every day, using differences to the 
fourth order. 

The whole of the calculations relating to the Minor Planets have, for the firet time, 
been performed at the Navricar Acmawac Office. 

Adopting as 2 basis the Elements of the Orbits given at pages vii and viii of the 
Navricar Atmawac for 1837, the Heliocentric Longituies have been first computed 
and the periods of the next Oppositions ascertained approximately. The only Oppo- 
sitions in 1838 are those of Vesta and Juno. For cach of these Planets the Variations 
of the Elements, caused by Venus, the Earth, Mars, Jupiter, and Saturn, have been 
computed for intervals of ight, days, for the whole period between the Oppositions, 
agreeably to the method described in Professor Ainy’s paper, “ On the Calculation 
of the Perturbations. of the Small Planets and the Comets of short period. — 
(Arrexprx to Navrican Ataranac, 1837, page 149).

With these Elements and their Variations for twenty days preceding and following 
the days of Opposition, the Ephemerides for Opposition were obtained. 

The Approximate Ephemeris for the year, of each of the Planets, Vesta, Pallas, and 
Ceres, was deduced from the Elements for 1837: for Juno the Elements for 1837 were 
used only to the period of opposition, and the new Elements for the remainder of the 
year. 

The Semidiameters of the Planets, for the Mean Distance of the Earth from the 
Sun, have been adopted es follow: e 


Mercury, Eq, Sem. 3°23 (Lindenau’s Tables of Mercury, page’S8) 
Venus, Eq. Sem. 8°25 (Delambre’s Astronomy, vol. ii. page 620)

Van 1802 (Paris, 1817), using the corrected Epochs given in the Navricat Aumanac 
for the Year 1832, and a difference of Meridians = 9™ 21". 

For the Configurations and Occultations of the Satellites, as well as the Transits 
of the Satellites and their Shadows over the disc of the Planct, Mr, Wootnovse’s 
Tables in the Arerxpix to the Navrtcat, Atmanac for 1835 have been used, 

The Mean Places of the 100 Principal Fixed Stars for Jan. 1, 1838, together with 
the Anoual Variations, have been deriyed from the fundamental Catalogue for 1930, 
contained in the Second Edilion of the Nauricar Ausanac for 1834, pages 362 to 
367, by means of the Formule at page xiv of the Parace to that Volume. 

The Logarithms of A, B,C, D, at page XXII. of each Month, have been com~ 
puted agreeably to the Formule at page 365, omitting only in the Values of C and I 
the terms — 0°004 sin 2 and — 0’"090 cos2 €; and for the only Stars that can be 
sensibly affected by the omission, viz. the five Polar Stars, a Table of

been computed from Busse1’s Formule, given at page $65, using the A, B,C, D, con- 
tained in this volume. 

The apparent places of 95 of the principal Stars have been deduced from the Mean 
Places for January 1, 1838, using the Variables A, B,C, D in the present volume with 
new constants computed for the year 1840, instead of the constants in the Astrono- 
mical Society's Catalogue for 1830. For the five Polar Stara the constants have 
been computed for 1838 and 1839, aud interpolated. The corrections were computed _ 
independently for every tenth day, with the exception of those for « and } Unsa 
Mrxonrts, which were interpolated, with second differences, from computations made 
for every third day of the year. 2 

A further correction of the right ascension for daily aberration is necessary, where 
extreme accuracy is required, and may be computed as follows: Let @ denote the 
latitude of the place, and 3 the declination of the Star, then the correction (in time) _ 
for the upper transit is, 

+ 0°°0206 cos p sec 3 


— 00206 cos sec 3 

The Lists of Moon-Culminating Stars and Occultations have been selected from 
‘Mr. Francis Baity’s Catalogue of Zodincal Stars. (London, 1827.) _ 

The Mean Places of the Stars for both Lists were taken in order of preference, 
1, From the Catalogue of the 100 Stars in this Work. _ 2. From Mr. Posp's printed 
Catalogue of 1112 Stars. 3. From the Astronomical Society’s Catalogue. The 
reduction of the Mean to the Apparent Places hus been performed by means of the 
Astronomical Society's Constants; the corrections for each star on the contiguous days 
being obtained by different computers for the Moon-Culminuting List, and those for 
the Occultations by duplicate computations, 

The calculations of the Elements of Occultations, the Occultations visible at Green- 
wich, and the Solar and Lunar Eclipses, have been made in duplicate, and in the 
manner described by Mr, Wootnovuse in the Appendix to the Naurican Arsrasac 
for 1836. 


The Elements at page 476, for determining the appearance of Suturn’s Ring, have 
been calculated by means of the formule: at page viii of the Naurican Aumawac for 
1836, adopting Brssex’s later determinations of the values of 8, ¢ anda’, viz, :— 

% = 166° 53’ 89 4 46462 (¢— 1800)

Bovyann’s Tables of Saturn, instead of 95421889, the value used by Brssus in the 
reduction of his observations,

E NAUTICAL ALMANAC AND ASTRONOMICAL EPHEMERIS 


FOR THE YEAR 1838, 









Axt the articles of the Ephemeris have been computed for Greenwich MEAN solar 
time; and where they are expressed for apparent solar or sidereal time, it has been 
chiefly for the convenience of astronomers. A day is the interval of time between the 
departure of any meridian from a heavenly body and its succeeding return to it, and 
derives its name from the body with which the motion of the meridian iscompared. The 
interval between the departure and return of a meridian to the Sun is called a solar 
day ; in the case of the Moon, the interval is called a /unar day; and in that of a Star, 
a sidereal day, The revolution of the Earth on its axis is always performed in the 
same time; and if the heavenly bodies preserved the same positions with respect to 
each other, the intervals between the departure and return of a meridian to ¢ach would 
be the same, and all days, consequently, of equal length. The San, (or, more strictly, 
the Earth in its orbit,) the Moon, and the Planets are, however, in continual motion 5 
and with velocities not only different from cach other, but varying in each partictilar 
body: the length of a day, as determined by any of these bodies, is therefore a variable 
quantity. 

| Astronomers, with the view of obtaining a convenient and uniform measure of 
| time, have recourse to a mean solar day, the length of which is equal to the mean or 
average of all the apparent solar days in 9 year, An imaginary Sun, called the mean 
Sun, is conceived to move uniformly in the Equator with the real Sun’s mean motion 
in Right Ascension, and the interval between the departure of any meridian from the 
mean Sun and its succeeding return to it is the duration of thé mean solar day. 
Clocks and Chronometers are adjusted to mean solar time; so that a complete revolution

A mere inspection of the columns of the Ephemeris is, of itself, suffic 
that the quantities are continually varying, and that some reduction i 
prlines nts are sfo tn gained ah By GS ee 
quantities are registered. Take, for instance, the Sun’s Right A

in all cases be required, even under the meridian of Greenwich, for which t] 
have been specially computed. Let a person be now supposed to be under 
15° West of Greenwich, The positions of the heavenly bodies, as referred to # 
of the Earth, are it of meridians, and are the same for all p 
same absolute instant; but the relative times at Greenwich and the assumed n 
would be different. If it were 1” from mean noon at the one place, it could 
from mean noon at the other; for when we speak of time, we mean, as Tega 
visible phenomenon, the distance of the Sun westward from a given meridian, 
the same absolute moment of time the Sun cannot be at the same distance (r: 
westward) from two meridians which are 15° distant from each other. Before we 
make use of the Ephemeris, it is therefore necessary to ascertain, in every insta 
distance of the Sun (in time) from the meridian of Greenwich, or what is con 


under the assumed meridian, increased or diminished by the difference (in time) 
two meridians, according as the assumed meridian is to the Weshoard or East 
Greenwich, In a mean Solar day, or 24 mean Solar hours, the Earth, by its rotati 
from West to East, has caused every meridian in succession from East to West to pass 
the mean Sun; and since the motion is uniform, all the meridians distant from each 
other 15° will have passed the mean Sun, at intervals of one mean hour; the meridian to 
the Eastward passing first, or being, as compared with the Sun, alwayseue mean hour 
in advance of the’ Westerly meridian. When it is 6" from mean noon place 15° 
‘West of Greenwich, it is therefore 7° from mean noon at Greenwich; and it is for this 
Greenwich time that we must deduce the quantities required from the 

Ifa chronometer adjusted to Greenwich mean time be at hand, the Greenwich time 
may be immediately obtained by applying a correction, deduced from the daily rate 
and interval elapsed, and this will be preferable in all cases for obtaining La id 
data from the Ephemeris. 

The day adopted in this Ephemeris is supposed to begin at mean acoenfeatiahthe 
instant when a clock or chronometer shows 0" 0" 0", Greenwich mean time, and is 
continued through the 24 hours, to the following mean noon, when another day begias. 
It may therefore be called the Mean Astronomical Day, although, in practice, astrono~ 
mere begin the day at the moment the true Sun’s centre is on their 

In the civil, or common, method of reckoning, the day is supposed to commence at 
the preceding midnight, and to be counted only to 12 hours or noon, when the 12 hours 
are reckoned over again to the next midnight. ‘The civil reckoning is therefore always

To cach month there are devoted twenty-two pages, distinguished by the Roman 
merals I. to XXII. 
Forconyenience of interpolation, the quantities that follow next in order of suc- 
ion have been added at the bottom of each page. Thus the quantities opposite 
February 1 will be found inserted also opposite to January 32, the number of the 
in cach month having been intentionally increased for such purpose. 


Page I. of each Month. 
The contents of this page are adapted to Apparent Noon, or the instant when the 
’s centre is on the meridian of Greenwich. The Sun’s Right Ascension, here given, 
Sore with Aberration, and reckoned from the true Equinox; it is therefore the 
Time at Apparent Noon, or the time which ought to be chown by a Sidereal 
Clock, at that instant. The Sun's Declination, at Apparent Noon, is the apparent 
@ngular distance of the Sun from the Equator, measured on the meridian, 

‘The columns entitled “Diff. for 1 hour” are intended to facilitate the reduction of 
‘the quantities from the meridian of Greenwich to any other meridian, The values of 
these quantities for any proposed mean time will, however, be more accurutely ascertained 
‘by means of the numbers on page II., from which, indeed, they have been derived. 

The Stdereal Time of the Sun's Semiidiameter passing the Meridian is useful for 
reducing a transit observation of cither limb of the Sun, when one only has been 
observed, to the transit of the centre. 

The Equation of Time is the difference between Apparent and Mean Time, and 
therefore serves for the conversion of either time into the other. The numbers here 
given, show, for Greenwich Apparent Noon, the distance of the mean Sun from the 
meridian, or the portion of time to be added fo, or subtracted from, (according to the 
precept at the head of the column,) Greenwich a Noon to obtain the corre-

in the Ephemeris which include the given distance, 
3. With the approximate interval and this difference, as arguments, take out the 
‘correction from the table. 
i. 4. If the Proportional Logarithms are decreasing, add the correction to the 
‘approximate time; ye ooong clam the result will be the accurate 
Greenwich mean time. 


Example 1.—Suppose it were required to find the Greenwich Mean Time, at which 
the true distance between the Moon and « Pegasi would be 42° 25’ 12” on May 15, 
1838. It appears, by inspecting the distances, that the time must be between XY" 
and XVIII": the nearest distance preceding, in order of time, the given distance is 
therefore the 





Distance at XV" - - 431153, and PLL. - = 3081

Difference - - - 04641 - - PL. + - 5861 
Approximate Interval - 1" 34" 54° - - PLL, = = 2780 


The difference between the Proportional Logarithms in the Ephemeris, at XY" 
and XVIII", is 46. Opposite to 1° 35” (or the quantity nearest to it, 1 30"), and 
under 46, in the Table, we have for the correction 14", which, subtracted from. the 
Approximate Interval, 1" 34” 54", because the Proportional Logarithms are increasing, 
gives 1" 34" 40°, for the true interval from XV": and hence the Greenwich Mean 
Time is 16" 34" 40", 

‘We see that, in the preceding Example, the omission of this correction would only 
produce an error of 3/5 in the Longitude. Cases may however occur, in which it 
would be 

Tt will sometimes happen, that the difference of the Proportional Logarithms will

with one-half or any fraction of the difference of the Proportional Logarithms and the 
Approximate Interval, and the corresponding correction increased in like proportion, 

Example 11.—Suppose it were required to find the Greenwich Mean Time, at 
which the true distance between the Moon and Aldebaran would be 17° 36" 16” on 
November 2nd, 1838. By inspecting the distances, it appears that the time must 
be between IX" and Midnight; therefore take the

Configurations of the Satellites of Jupiter, ; 

In addition to the explanation given at the foot of the page, it may 
that when two Satellites are in or near conjunction, instead of the usual s 
it has been thought better to place one above the other, without regard t 
latitudes, but merely to distinguish them in their relation of upper and lor 

‘The Satellites arc'in the superior parts of their orbits, or have Jup

in the former case Eclipses and Occultations occur, and in the latter

If an inverting telescope be directed towards Jupiter on March"17, 1

‘invert, Jupitér being always to the South of the zenith of Greenwich, the Satellites 
are here laid down on the left of Jupiter would appear to the West, and those on

‘As regards their positions to the east or west, the page viewed direetly, exhi- 
Dits the Satellites in an inverted order; but if the leaf be turned over, and the page 
‘Yiewed from the other side, they will appear in their real positions. The simplest 
mode of changing the position of a Satellite from apparent to real, and nice vers, 
is to draw a line from the Satellite through Jupiter’s centre, and to place the Satellite 

this line at the same distance from the centre as before, only on the opposite 
‘side. If this operation be performed upon the Contigurations as laid down in this 
volume, the Satellites will be reduced to their real positions. 

As the Configurations are given for Mean Astronomical time, which agrees with 
Civil time only from 0" to 12", or from noon to midnight, when the time exceeds 12” 
the excess will indicate the Civil time of the succeeding day of the month. 

Thus in November, 1838, the Configurations are given for 17° 30" mean time, but 
the 17th hour from noon is the same as the 5th hour from the following midnight, 
when a new Civil day has commenced. The appearances, therefore, relate to 5* 30" 
A.M. of the day following, according to the common mode of reckoning time; that is, 
the Configurations at 17" 30" on November the 26th relate to 5" 30" A.M. on 
November the 27th. 

‘The Configurations enable an observer to distinguish the Satellites from each other, 
and from Stars in the vicinity of Jupiter.

Eclipses of the Satellites of’ Jupiter. 

On this page are given the Mean and Sidereal Times of the Eclipses of the Satellites, 
together with diagrams exhibiting the position of each Satellite with respect to the 
disc of the Planet at the moment of Immersion or Emersion, as it will appear in an 
inverting telescope. ‘These diagrams have been laid down from calculations made for 
the eclipse nearest to the middle of cach month; but they will serve very well for the 
whole of the month, except near opposition, the change in the position of Jupiter and 
his Shadow in the interval being too small to be appreciable by the eye, as is 
evident by comparing the Phases for any two successive months. All the Eclipses 
which happen when Jupiter is 8° above, and the Sun 8° below the horizon of Green-

1, Logarithms of A, B, C, D, for correcting the Places of the Fixed Stars. 

Tn the formule which express the relation of the apparent place of a Star to its 
mean place, and reciprocally, there are certain factors which are independent altogether 
of the Star's place, and are therefore common to all Stars. These factors depend 
upon the longitudes of the Sun, Moon, and Moon's ascending Node. 

The Logarithms here given are the logarithms of these independent factors, conve- 

niently arranged for incorporation with other terms depending upon each particular 
Star, according to the method recommended by Professor Bessel. ‘They have been

2, Mean Time of’ Transit of the First Point of Aries. 

‘The time in this column shows the distance of the mean Sun from the meridian, 
the instant when the (rue point of intersection of the ecliptic and equator (called 
- the first point of Aries) is on the meridian of Greenwich ; and as the distance of the 
GRRL geil of Asste frtex the vaeridlins,-a( dhe tualant the ined Guise tw Gaiiiicadaaas 
‘is denominated Sidereal Time at Mean Noon, this may, by analogy, be termed the 
Mean Time at Sidereal Noon. It is the time which ought to be shown by & mean 
‘time clock adjusted to the Greenwich meridian, at the moment that a clock, adjusted 
to sidereal time, indicates exactly 0' 6” 0°. The use of this column is to facilitate the 
reduction of sideresl to mean solar time, with the help of the Table of Time Equiva- 
dents, given at pages 488 and 489, of this volume, as has been already explained at 
page 500. 





3. Mean Equinoctial Time. 


Mean Equinoctial Time signifies the Mean Time elapsed since the inetant of the 
Mean Vernal Equinox. The numbers in this column represent this time, at every 
Mean Noon, in Mean Solar days and fractional parts of a day; it is reckoned from 
the Mean Vernal Equinox of 1837, between Jannary 1‘ and March 227463822, but 
after March 22%-463822 from the Vernal Equinox of 1838; for the Equinoctial Year 
has been assumed, according to Bessel, (Conn. des Tems, 1831, Additions, page 154) 
equal to 365°242218 Mean Solar days; and as the Equinoctial Time corresponding to 
the Mean Noon of March 22, 1838, is 364°778395, it is evident that the 
Year of 1837-8 was completed, and that a new year commenced, at "463822 after 
Mean Noon of the 22nd, 

‘The fraction of the day at the head of the column is common to all the days of the 
Equinoctial Year. Thus, at Mean Noon of January 19, 1838, the Equinoctial Time 
is 302°-778395, and on January 20 it is 303/+779395, and so on until March 
224 463822, when the year terminates, and the fractional part of the day 
At Mean Noon of March 23, 1838, the Equinoctial Time is 0"*536178, and this 
fraction is to be annexed to all the numbers in the column of days, from the period 
of the change until the equinox of 1839. 

At the instant the Mean Sun arrives at the Mean Vernal Equinox, it must also be on 
some meridian, and this meridian will then have its Equinoctial time corresponding 
with its Mean Solar time, each of which will be 0° 0" 0°, and they will continue to 
correspond throughout the Equinoctial Year. At the end of the Equinoctial Year, 
the Sun will have passed this méridian 365 times, and have performed, besides, a 
certain portion of its 366th diurnal revolution, viz. 0* 242218 ; it will, therefore, have 
arrived at some other meridian, which will now, in its turn, reckon the Mean Equi- 
noctial and Mean Solar time from the same point, and remain constant for the year. 
Thus the meridian, from which the time is reckoned, is shifting its position at the 
end of every year by 0° 242218, or 5" 48™ 47°64, to the Westward. Between the 
Vernal Equinoxes of 1838 and 1839, this itinerant meridian corresponds to Longitude 
0° 536178 or 12° 52 5* 78 East of Greenwich, 

This species of time was first introduced in the Supplement to the Nautical Almanac 
for 1928, with very full explanation of its nature and use. It there appears, that 
the use of Equinoetinl Time is to afford an uniform date, which shall be mdependent 
of the different meridians, and of all inequalities in the Sun’s motion, and shall thus 
save the necessity, when speaking of the time of any event's happening, of mentioning

Obliquity of the Ecliptic. (Page 266.) 


‘The apparent inclination of the plane of the Ecliptic to that of the Equator is here 
given for every LOth day of the year, and continued to January 6 of the fol 
ing year, marked December 37 for the sake of convenience. This 
is ever varying, as well from the effect of its mean diminution, as of the nu- 
tation of the carth’s axis: it is an important clement in ‘positions 
of the heavenly bodies, with reference to cither of the planes, when we know 
their positions with respect to the other; as, for instance, in

quity in the ten days between Angust the 9th and the 19th, is 0"*10, or 001 for

Sun’s Horizontal Parallax. (Page 266.) 


‘The Sun's Horizontal Parallax is the greatest angle under which the equatorial 
emidiameter of the earth would appear at the Sun’s centre. It varies inversely 
as the distance, and the numbers in this column show the values for every tenth day 
of the year, 

‘The Parallax serves for reducing a Solar observation made at the surface of the 
earth to what it would have been if made at the centre. 


Sun's Aberration, (Page 266.) 


The progressive motion of light, combined with the motion of the Earth in ite orbit, 
‘causes the Sum to appear in a different position from that which he occupies, 
the true position being always in advance of the apparent. The numbers in this 
column indicate, for every 10th day of the year, the amount of Aberration, or the 
quantity to be applied to the true longitude of the Sun to obtain the apparent 
longitude. The longitudes derived from the Solar Tables include Aberration, and are 
therefore apparent longitudes, such as are contained in this Ephemeris. If the trae 
longitude of the Sun be wanted, as is the case in finding the longitude of the Earth 
for the calculation of the Geocentric place of a body, the aberration must be applied 
with a contrary sign, Thus, on June 9, 1838, at Mean Noon, by adding 20°05, 
the amount of aberration, to 78° 8° 11, the apparent longitude of the Sun, we 
obtain 78° 8’ 21/15 for the true longitude. 


Equation of the Equinores. (Page 266.) 


‘The Solar and Planetary Tubles furnish us with the places of the Heavenly Bodies 
referred to the Mean Equinox; but the true place of the Equinox at any time differs 
from its mean place, by a quantity which is termed the Equation of the ; 
and the numbers here given show the value of the Equation for every 10th day of 
the year. They are to be applied, with their proper signs, to the Longitudes reckoned 
from the Mean Equinox, to obtain the values with respect to the True Equinox.

‘The small figures on the right hand of the vertical columns of seconds represent the 
differences of the quantities above and below them on the left, or the variation of 
Right Ascension ond Declination in 10 daye, and serve to find, by interpolation, the 
values for any intermediate day. As in the case of the Planets before explained, a 
Star will sometimes arrive at the meridian twice in one Mean Solar day. Wherever 
this occurs, an asterisk is placed opposite to the interval, and it signifies that the Star 
has passed the meridian 11 times in the 10 Mean Solar days, and consequently that 
the Right Ascension or Declination on any intermediate day is to be determined in 
these particular instances by taking ,';th part, instead of y'yth, for the daily variation in 
the interval. Thus, at page $85, we find in the instance of « Argus, an asterisk 
opposite the interval between August J and 19, and a difference of 0°08 opposite to the 
interval between the seconds belonging to those dates; we therefore infer that 11 transite 
have taken place, and that the daily variation of the Right Ascension is 0*:007, 

When extreme accuracy is required, the apparent places of the 5 Polar Stars demand 
a further correction, depending on the terms which involye2¢. The apparent places 
do not include these corrections, on account of the rapid variation of the argument, 
viz. about 26° in a day, but they are given in a Table at pages 408, 409, for every 
degree of the Moon’s Longitude, and may he readily applied, agreeably to the precept 
at the foot of that Table. 

Formule for correcting for daily aberration are given in the Preface. 


Moon-Culminating Stars, (Pages 410 to 451.) 


‘Those Stars are denominated Moon-Culminating Stars, which being near the 
Moon’s parallel of Declination, and not differing much from her in Right Ascension, 
are proper to be observed with the Moon, in order to determine differences of meri- 
dians. ‘This is effected by comparing the differences of the observed Right Ascensions 
of such a Star and the Moon's bright limb at any two meridians. If the Moon had no 
mation, the diference of her Right Ascenslon from that of the Stax woul le eonetant at

of the Moon and the-times of High Water on full ancl days. They serve 
to determine the time of high water on any other day at places in the usual 
manner. The time of high water, however, at any of the places contained in this 
table, may be deduced for every day from the time of high water at) London Bridge, 
by taking the difference between the establishment of the port at each of these places, 
and the establishment of the port at London Bridge, viz. 2" 7", and considering this 
a a constant quantity, representing the difference of the tides between London Bridge 
and the place, to be added to, or subtracted from, London, Bridge tides, according as 
the establishment'of ‘the port ef the piace, {a Jaler, or earlier thaw et at Laniion 
Bridge. Thus the establishment Oe 12", and at Loudon 
Bridge 2" 7" ; the difference is 0" 55", and the Aberdeen. tide precedes that at Lendoni: 
therefore, by subtracting 0* 55" from the London Bridge tides, we obtain the Aberdeen 
tides in mean time. On February 19, 1838, the first high water at London Bridge 
occurs at 8" 35", which being diminished by 0" 55", gives 7" 40™ for the correspond 
ing tide at Aberdeen, and so for other places.
