PREFACE.
The general course of observations, and the principle and arrangement
of the reductions, for the year 1835, differ in no respect from those of
preceding years.
On the 1st of October I commenced the general superintendance of
the Royal Observatory at Greenwich. My residence at Greenwich, how-
ever, did not begin till the latter part of December. In the interval
between these times, my attention was divided between the two Obser-
vatories. The reductions, therefore, which were made in the last three
months of the year, have not received so much of my personal examina-
tion as those of the earlier parts. T believe, however, that the measures
which were taken for verifying the computations will be found to have
ensured their general correctness. The final arrangement of the results
was entrusted in a great degree to Mr Glaisher : who had then taken
the situation of Assistant at the Royal Observatory, but was indulged
with leave of absence by the Lords Commissioners of the Admiralty for
this express purpose.
The reductions for Halley's Comet were also made by Mr Glaisher :
but as these appeared peculiarly liable to errors, I have myself examined
every part of them.
A few observations of various kinds, made under my direction, and
on the same general plan in the year 1836, are included in the present
Volume.
In finally quitting the connexion with an Institution, whose efficiency
has been for several years the first object of my wishes, and whose fair
reputation has been my pride, I must congratulate the University, and
the friends of the Observatory, on its immediate prospects under the
direction of Professor Challis. And I tnist that nothing will at any
distant time occur to disable an Observatory, which, though necessarily
limited in personal establishment, yet from the excellence of its instruments
and the peculiarity of its connexion with the University, may compete, in
regard of general utility, with any similar institution.

CAMBRIDGE OBSERVATIONS.
INTRODUCTION.
The Transit Instrument was constructed by DoUond in 182J^. Its focal
length is nearly 10 feet, and the aperture of the object glass is 5 inches. In
general, the whole aperture is employed in observing. During the whole
of 1835, the instrument has been covered with a covering of oiled silk ;
and the Sun has never been allowed to shine upon it before the observation
commenced. It is presumed therefore that the transits in the following
pages are free from all effects of solar heat. The piers are very massive.
The pivots of the transit are of beU metal, turning in brass Y's which have
the usual adjustments ; no alteration has been made in the screws for either
vertical or horizontal adjustment in the year 1835. The Y's are somewhat
worn and scratched, but the pivots are in a very good state. The wires
are of silk from the silk-worms ball, and they subtend an angle of less
than 1" (their thickness being less than —^ of an inch). The present system
of wires was fixed at the end of 1832: no alteration has been made in their
position during the year 1835. The power usually employed is about 140.
The clock was constructed by Hardy, with Hardy's escapement: its beat
is remarkably loud and distinct. The only alteration which has been made
in the clock is the occasionally putting forward the minute hand.
The original observations with the transit (as well as with the other
instruments) are entered in small memorandum-books, in which the writing
cannot easily be effaced : these are carefully preserved for future reference.
The following is the explanation of each of the columns in the tabular
part of the work, and of the methods by which the numbers in those columns
have been obtained.

page (1) to (79).
b
VI INTRODUCTION.
The first column on the left hand contains the day of the month in
apparent solar time.
The second column contains the names of the objects observed. With
regard to the nomenclature of stars, the following is the order of preference
in which the names have been taken.
1. The propel- name of the star (as used in the Nautical Almanac
1834, 2d Edition).
2. The Greek or Roman character, with the name of the constellation,
(as given in the Royal Astronomical Society's Catalogue).
3. Flamsteed's number.
4. The number in the Royal Astronomical Society's Catalogue.
5. Piazzi's number.
6. The approximate N.P.D., which may be erroneous 3' or 4'.
In the observation of a double star it is always to be understood (if
not otherwise expressed) that the brighter star was observed. 7 Virginis
is observed as a single star.
The seven succeeding columns contain the times of transit over the seven
wires. It is to be remarked that it is the practice to look at the clock-face
before the transit over the first wire, to take a second, and then to count
(listening to the beats), and not to look again at the clock-face till the object
has passed all the wires. Thus it can rarely happen that any one wire is
affected by an error which is not common to all. Errors in the minutes are
very common, and are not noticed in the notes : errors of 5 or 10 seconds
sometimes occur : and very rarely errors of V; occasionally also there seems
reason to alter a single wire by V. All alterations of the seconds are care-
fully mentioned in the notes. The hour and minute are always those
corresponding to the wire last observed.
A micrometer wire in the eyepiece of the transit (parallel to the fixed
wires, and moveable in a horizontal direction by means of a screw of which
one turn = 17",06 nearly) is sometimes used for transits of Polaris and
5 Ursas Minoris. The reading of the micrometer on coincidence with the
middle wire is first found by taking the mean of the readings when it
INTRODUCTION. VU
touches the middle wire, three times on each side: then the micrometer is
turned 1, 2, and 3 revolutions on each side of that position, and used as so
many distinct wires. The mean of the transits represents therefore an ob-
servation on the middle wire. The readings of the micrometer are given
in the notes : and the transits over the micrometer wire are printed in a
smaller type than those over the fixed wires.
The tenth column contains the correction to be applied to the mean of
the wires actually observed, in order to obtain the mean of the transits over
the seven wires (errors of observation excepted), supposing all employed.
The intervals of the wires are deduced from 12 observations of Polaris and
19 observations of S Ursse Minoris, between Jan. 4 and Feb. 27, 1833. The
following are the tables used in the calculation of the numbers of the 10th
column. The wires are distinguished by the letters A, B, C, Z>, E, F, G:
and stars above the pole pass them in this order when the illuminated end
of the axis is East.

For the planets, besides the secant of declination, a factor is used,
depending on the daily increase or diminution of right ascension : for the
Sun, the factors are used which are given in the Supplement to the Nau-
tical Almanac for 1 833 : for the Moon, the factors are calculated by the
formula

factor = — ^-.^^ — X —. — =r-f -s X secant Moon s declination,
3600 sin Moon s apparent ZD
where / is the increase of the Moon's M in passing over 1" of terrestrial
longitude, given in the Nautical Almanac, page 410.
In the observation of Jupiter and Saturn, it is usual to observe the first
limb over A, C, E, and G, and the second limb over JB, D, and F. The
mean of each of these sets coincides so nearly with the mean of the whole,
that it has not been thought worth while to apply any correction.
The eleventh column contains the concluded time of transit over the
imaginary line which is the mean of all the wires.
The twelfth column contains the initial of the observer's name. Those
marked A are by myself, those marked B by Mr Baldrey, and those
marked G by Mr Glaisher.
The first column on the right hand page contains the error of coUimation,
which is determined by the following process : A mark on Grantchester steeple
(about 2^ miles to the S.) and a wire in a coUimating telescope (supplying
the place of an object infinitely distant on the N. side) are observed with
the transit, the micrometer wire being employed to measure the distance of
INTRODUCTION. IX
each from the middle wire. The same measures are made when the transit
has been reversed. Each mark gives a value for the error of coUimation :
and the mean of the two values is free from the effect of displacement of
the axis by reversion. This mean is corrected for the difference between the
middle wire and the mean of the seven wires. It is considered positive when
it implies an additive correction to the time of transit of an object above
the pole. The quantity — 0",2 is then applied algebraically, to take account
of diurnal aberration. The result of these operations is the quantity in the
tables.
The following are the observations by which the error of collimation has
been determined in the year 1835 (that used for Jan. 1 having been taken
from the observations of 1834, Oct. 9).
Jan. 2, 0*". Observed the cross and collimator as usual. The cross rather
faint, but steady : a very small motion perceptible when the wire was on
it. The wire of the collimator very well seen : a very small motion apparent
in it.

well. The cross unsteady, though the Sun was not shining.

Hence the apparent error of coUimation for D, illuminated end West,
is O^OSO = 0",85. As the micrometer readings increase when the wire is
moved from the illuminated end, the negative sign is to be attached to
this quantity. Correcting it for diurnal aberration, the error of coUimation
for Z> is — 1",00, and that for the mean of the wires — 1",07, the illuminated
end being West.

INTRODUCTION. XI
The apparent error of coUimation for D is therefore O^OSS = 0",54 with
negative sign (illuminated end East). Corrected for diurnal aberration and
for the distance of D from the mean of the wires, this gives error of coUi-
mation for the mean, illuminated end East, = - 0",6.
The numerical correction to each transit, in seconds of time, is -7- x error
of collimation x cosec N.P.D.
The second column contains the value, in seconds of space, of the eleva-
tion of the western end of the axis (considered negative when the eastern
end is the higher). It is always ascertained by six applications of the spirit-
level, reversing the level on each application : the excess of the sum of the
six western readings of the bubble over the sum of the six eastern readings
is divided by 12, and + 0^,15 is added to the quotient if the illuminated
end is East, or - 0^,15 if the illuminated end is West. This quantity de-
pends on the difference of the diameters of the pivots, as found in Vol. i.
and II. The operation of levelling is commonly performed once in a week.
It was found in 1834 (see the Observations for 1834, page xii.) that
one part on the level-scales = 1",3. By this factor the error of level, as
expressed in divisions of the scales, has always been multiplied to obtain
the result which is set down in the second column of the right-hand page.
The numerical correction to each transit, in seconds of time, is -— x level
15
error x cos (N.P.D. - 37". 47') x cosec N.P.D.
The third column contains the seconds of the transits of those stars by
which the meridian error is ascertained (the transits being corrected for
error of collimation and level error). These are therefore the times at which
those stars would pass the vertical great circle whose azimuthal deviation
is the same as that of the inclined small circle described by the axis of
the transit-telescope.
The fourth column contains the value of the Meridian Error or azimuthal
deviation in seconds of space, considered positive when the telescope points
to the E. of the S. point, and to the W. of the N. point. It is always
determined by consecutive opposite passages of Polaris or ^Ursee Minoris,
XU INTRODUCTION.
in this manner. If the clock had no rate, and if the star's right ascension
did not alter, the meridian error, in seconds of space, would be found by
subtracting the time of transit below the pole from that above the pole
(removing 12'' from the difference) and dividing the difference in seconds
of time by 2,94 for Polaris or by 1 ,37 for <5 Ursas Minoris. The only
modification introduced by the clock's rate and by the alteration of right
ascension is, that the clock's loss and the decrease of right ascension in 12"
must be added to the second transit, whether above or below the pole. If
three consecutive passages have been observed, there is no need to consider
the clock rate, &c., inasmuch as these quantities will increase the difference
between the first two, and will as much diminish the difference between
the second two, or vice versa, and therefore the mean of the differences
will be free from the effects of these quantities. If several consecutive
passages have been observed, I have commonly taken the differences, have
taken the mean of each pair of adjacent differences, and have considered
this mean as the quantity proper for giving the meridian error applicable
to the transit separating the two differences of that pair: the first and last
transits are commonly corrected by the meridian error corresponding to the
first but one and the last but one.
The correction in seconds of time to be applied to each transit is
— - X meridian error x sin (N.P.D. - ST". 47') x cosec N.P.D.
15
The limits between which each of these errors is used are marked by
the bars across the column.
The fifth column contains the seconds of every transit, as corrected for
the three errors of coUimation, level, and azimuth. The numbers corre-
sponding to the Sun, Jupiter, and Saturn (when both limbs are observed),
have a bracket before them : it is to be understood here, that the mean
of the uncorrected transits of the two limbs has been corrected in the same
manner as other transits. In the corrections for the Moon, no allowance is
made for the Moon's motion in right ascension.
The sixth column contains the seconds of the calculated apparent right
ascensions of the stars used for determining the clock error. Among these

Polaris and ^ Ursas Minoris are always included, not in order to give a
clock error which can be used with the others, but in order to give the
reader the means of judging of the instrument's position when there is no

The right ascensions of these stars were originally taken from the Nau-
tical Almanac of 1829: they have been corrected by the observations of
the succeeding years according to the methods explained in the different
volumes of the Cambridge Observations, leaving the mean of all (except
Polaris and S Urs« Minoris) nearly unaltered ; each place corrected by a
sufficient number of observations in one year being adopted as the funda-
mental place for the next year. The mean exceeds the mean for the same
stars in Mr Pond's catalogue of 1112 stars by 0^11, and exceeds the mean
for the same stars in Bessel's catalogue {Tabulce RegiomontancB) by 0^19. It
appears from a discussion of the observations of the Sun made with the
Transit and the Mural Circle in the year 1833, {Memoirs of the Royal
Astrottomical Society, Vol. viii.) that the right ascensions ought to be dimi-
nished by 0^18 : and by a similar discussion of the observations made in
the year 1834, {Memoirs of the Royal Astronomical Society, Vol. ix.) that
c
XIV INTRODUCTION.
they ought to be diminished by 0%15: thus making the mean of the cata-
logue to coincide ahnost exactly with the mean of Bessel's catalogue. But
for the sake of using the same place of the equinox, and the same catalogue
(in all fundamental points) which has been used in the Cambridge Observ-
ations since their commencement in 1828, I have deemed it not yet advisable
to alter the right ascensions of the fundamental stars.
The apparent right ascensions are found by adding to the apparent
right ascensions of the Nautical Almanac 1835, the excesses given in the
table above. Thus the corrections adopted are the same as those of the
Nautical Almanac. They assume the constant of aberration = 20",36, and
that of lunar nutation = 9",25. For the stars whose passage below the
pole is observed, the right ascension is interpolated between those for the
preceding and following passages above the pole. For Polaris and ^Ursee
Minoris the corrections are applied which depend on the Moon's longitude,
and which are given in the Nautical Almanac, page 408.
The seventh column contains the clock error as shewn by each star: it
is the excess of the apparent right ascension over the corrected time of
transit.
The observations are divided into groups, whose limits are marked by
the bars across the eighth and ninth columns. The mean of the clock errors
in each group (excluding those given by Polaris or ^ Ursse Minoris) is
considered to correspond to the mean of the times of transit of the stars
furnishing the clock errors; by comparing this with the mean of the
preceding group and the mean of the following group, a preceding and a
following clock rate are obtained: from these a rate is determined which
is assumed to hold uniformly through the group (for the method of deter-
mining which no general rule can be given), and this rate is set down in
the eighth column. This rate is applied backwards to the mean clock error
just mentioned, so as to give the clock error when the clock shewed 0\
and this quantity is set down in the ninth column. As the observations
frequently extend into more than one sidereal day, the error is set down
which corresponds to the O'' preceding each observation of the group.
INTRODUCTION. XV
The apparent right ascension in the tenth column is formed by adding to
the corrected transit (column 5) the clock error at 0" (column 9) and the
proportional part of the rate (column 8). No apparent right ascensions are
given for Polaris or 5 Ursae Minoris, unless one of those stars has been
observed at consecutive passages: and none are given for other fundamental
stars, unless three at least, excluding Polaris and ^ Urs£e Minoris^ are con-
tained in the group.
Sidereal Times occupied by the passages of the diameters of the Stin, the
Moon, Jupiter, and Saturn, over the Meridian, pages (80) and (81).
These numbers for the Sun, Jupiter, and Saturn, are merely the differences
of the " Concluded Transit over the mean of the Seven Wires" for the first
and second limbs. For the Moon a small correction is necessary, as it is
hardly possible that both her limbs can be quite full. This correction is
investigated by ascertaining the Moon's distance (in M) from the point of
opposition to the Sun : this distance multiplied by the cosine of the Sun's
declination is the length of the arc of a great circle drawn perpendicularly
from the Sun's place upon the meridian passing through the Moon's place;
and the correction required is the versed sine of this arc, on the Moon's
surface : always additive to the observed diameter. In two of the instances
in the table the correction is 0',04 : in the third it is insensible.
Apparent Right Ascensions of Polaris and S Ursce Minoris, and Mean
Right Ascensions of Stars observed in the year 1835; page (84) to (94).
The apparent Right Ascensions of Polaris and ^Ursse Minoris are merely
extracted from the tenth column, right-hand page, in the " Transits as observed
&c." It has been mentioned that none are retained except when consecutive
passages of one of these stars were observed, and when consequently the
meridian error was well known. With one exception also, none are retained
in which the observation was made over less than three wires. The process
of determining the meridian error, as explained above, takes account of the
variation of right ascension between the two passages. Nothing is omitted
therefore in these determinations : and I believe that they are worthy of
great confidence.

XVI INTRODUCTION.
The mean right ascensions of these and all the other stars are formed
by subtracting the corrections from the apparent right ascensions in column
10 of the " Transits as observed, &c." For the stars in the list of the
Nautical Almanac, the requisite corrections are found by subtracting the
mean right ascensions of that work from the apparent right ascensions of
the same work (those of Polaris and 5 Ursee Minoris being affected with
the corrections depending on the Moon's longitude). For the stars in the
Royal Astronomical Society's Catalogue not included in the list of the Nautical
Almanac, the corrections are calculated by the formula Aa + Sb + Cc+ Dd;
log A, log JB, log C, and log JD, being taken from the Nautical Almanac
without alteration, and log a, log b, log c, log d, being taken from the Royal
Astronomical Society's Catalogue. For the stars not included in that Cata-
logue, the corrections are calcidated by the formula — A . cos M cosec N.P.D.
+ --B .sin M cosec N.P.D. + t^ C x (n° log = 1,3020) x sin M cotan N.P.D.
+ ^D.cos M cotan N.P.D. + C x (n° log = 0,4869).
The Catalogue given in pages (93) and (94) contains the mean of all the
different values of mean R.A. of each star. It must be remembered that
these are subject to the same error, from error in the place of the equinox,
as the mean R.A. in the Nautical Almanac for 1829- The annual varia-
tions are taken from the Astronomical Society's Catalogue, or are computed
by the same formula which is used there.
Zenith Distances observed with the Mural Circle, and Calculation of
Geocentric North Polar Distances, page 1 to 105.
The mural circle with which these observations were made was con-
structed by Troughton and Simms. It is 8 feet in diameter, but in all
other respects is similar to the mural circles of the Greenwich Observatory.
The limb is connected with the center piece by 16 spokes (hollow cones) :
and these spokes are connected at about the middle of their lengths by
bars forming a circle whose diameter is about half that of the exterior
circle. The limb was cast in several pieces, which were afterwards united
by the process technically called burning together; a process which, when
INTRODUCTION. XVll
skilfully performed, makes a connexion as perfect as if the whole had been
cast at once. The axis on which the circle turns is a hollow cone i^ feet
long, passing through a very massive stone pier (the circle being on its
eastern face) : both bearings of the axis are on the same side of the circle.
At both bearings the axis is armed with a steel ring, which turns within
a steel cylinder. A considerable part of the weight at the bearing of the
large ring (or that near the circle) is supported by lever counterpoises.
The divisions of the limb are on the external edge, so that the microscopes
by which they are read are in the same plane as the circle: the intervals
of the divisions are 5'. The divisions were cut after the circle was mounted
on the pier. The microscopes are attached to the stone pier by brass sup-
ports, the height of which above the point of attachment is intended to
supply a thermometrical expansion nearly equal to the upward expansion
of the central support. The eyepieces of the microscopes are fitted with
micrometers, by which the intervals of the divisions are subdivided: in ob-
servation the subdivisions are always read to tenths of seconds. The tele-
scope is carried by a steel rod passing through the center of the conical axis :
it is however fixed in its position by frames which are clamped to the limb
at both ends of the telescope. One of these frames is as near as possible
to the object-glass-cell, and the other as near as possible to the wire-frame.
In the eyepiece there is one fixed horizontal wire, of spider's web, adjustible
by a screw to horizontality, and one wire parallel to it moveable by a mi-
crometer screw : there are also five vertical wires. The instrument is fixed
or moved slowly by five clamps, with tangent screws acting immediately
on the limb ; two of these however have been taken off (to diminish the
friction), but can be restored in a few minutes.
That the radiation of the Sun may produce no injurious effect in observ-
ations of the Sun or of bodies near the Sun, a wooden screen is provided,
consisting of three parts: two of which are designed to screen all those
parts of the limb which are beyond the zenith distances corresponding to
the solstitial points, and the third (a sliding board with a hole little larger
than the object glass of the telescope) protects all those parts of the limb
between the two solstitial points. It is impossible that the Sun's warmth can
have produced the least effect on any of the succeeding observations.
XVIU INTRODUCTION.
When there is no reason for departing from the usual practice, the circle
is set approximately for the object to be observed, it is fixed by the clamp
nearest to the observer's hand, and then by the tangent screw it is moved
till the fixed wire bisects the star or touches the planet under observation
(an attempt is always made to bisect the thickness of the wire by the limb
of a planet). The heads of the tangent screws have been notched in such
a way that the observer, without looking to them, can tell whether he is
moving the circle by the screw in opposition to the spring of the clamp
(which is preferred to the contrary motion, as less liable to be followed by
a slip of the circle). When two observations follow each other very closely,
the circle is clamped nearly in the proper position, the microscopes are all
read, and then (without moving the circle or telescope) the object is bisected
or touched by the micrometer wire : this operation requiring very little time,
allows the next observation to be taken very soon after the first. This method
is ahvays used for the observation of a quick-moving star (and sometimes
for that of a slow-moving star) by reflexion and directly at the same passage :
it is also used for the observation of both limbs of the Sun or Moon.
When there is no reason to the contrary, the bisection is always effected
(as nearly as possible) when the object passes the middle vertical wire; but
in such cases as those mentioned above, one observation is generally made
a little before and the other a little after passing the middle wire : if their
alteration of zenith distance in this time has been perceptible, it is allowed
for by numerical correction. The Moon's limb is frequently observed several
times with the micrometer wire; a correction is then necessary for the
change of polar distance at each observation.
The following tables contain the particulars of two examinations of the
divisions of the circle in the year 1835. The sum of opposite readings only
is used (so that the effect of this examination is to determine diametral
errors only). The sum of the readings of A ■{- B, C + D, E -{■ F, being di-
vided by 3, and A + B being diminished by this quantity, it is clear that
the accidental position of the division in the field of view is eliminated
from the remainder. Thus A + B - - sum may be supposed to depend only
on the position of the microscopes A and B, the error of division, and the
INTRODUCTION. XIX
error in reading the divisions (whether produced by a change in the figure
of the circle or by any other cause). Assuming the values of the two
latter quantities to be periodical, the mean of all the quantities A + B — - sum
o
is the error in the position of the microscopes: this being applied with
sign changed to each particular value in that column, leaves a quantity
A + B — - sum — constant, which depends only on the error of division and
o
the error in reading the divisions. Selecting all those values for which the
same divisions are observed (remarking that the divisions which were under
A and B with the pointer-reading 10" are also under A and B with the
pointer-reading 190°, and are under C and D with the pointer-reading 70"
and 250", and under E and F with the pointer-reading 130" and 310", &c.)
and taking the mean, the errors of division are found. Applying these with
sign changed to A + B — - sum — constant, the variations of the readings
of the same divisions in different positions of the circle are found.
The general coincidence of the results, as to error of division, witli eacli
other and with those of the two preceding years, gives strong reason for
thinking that reliance may be placed on this method of examination, and
that the anomalous errors of division are trifling in comparison with the
very small error which appears to follow a law.

XXIV INTRODUCTION.
I shall now proceed with the explanation of the different columns in the
Zenith Distances observed with the Mural Circle, &c.
Column 1 contains the day, beginning always with the Sun's passage.
Column 2 contains the name of the object observed, with letters indi-
cating the method of observation. R denotes that it is observed by reflexion
in a trough of mercury : M that it is observed with the micrometer wire
(the reading of which is given in column 10). The limb of a planet which
is mentioned in column 2 is that which is observed with the fixed wire : the
other limb is commonly observed with the micrometer wire (the reading for
which is set down in column 8 of the right-hand page). The rules for the
nomenclature of the stars are the same as in the Transits observed, &c.
except that when other references fail the star's place is described by its
approximate M., which may be erroneous 3' or 4\
Column 3 contains the indication of the pointer. This is merely a pointed
index fixed to the stone pier; and column 3 contains only the degrees and
the whole number of divisions (of 5' each) which it marks.
The position of the pointer is such that its reading is greater than the
division under Microscope A by 10" . 40'. The pointer reading, as first set
down, is frequently erroneous by some multiple of 5': no mention is made,
in the notes, of these alterations.
Columns 4 to 9 contain the readings of the six microscopes (the minutes
being set down in column 4 only). It must be remarked that the microscopes
are lettered in the following order :
E C
B A
D F
so that the readings of A and B are those at opposite ends of one diameter,
the readings of C and Z> are at opposite ends of a diameter inclined 60' to
the former, and the readings of E and F are at opposite ends of a third
diameter inclined 60° to each of the others. Once or twice the minute
INTKODUCTION. XXV
has been set down wrong, but other observations of the same object (inde-
pendent of catalogues) have given the means of correcting it : and no mention
is made in the notes. The seconds are sometimes set down wrong, but every
alteration of them is carefully recorded in the notes.
Column 10 contains either the reading of the micrometer for the body
or limb mentioned in column 2, or the time shewn by the clock near the
circle at the instant of bisection, or, in a few instances, both these quantities.
To reduce an observation of the micrometer wire, the micrometer reading
in column 10 must be subtracted from the reading at coincidence with the
fixed wire (given at the bottom of the right-hand page), and the difference
(considered negative if the reading in column 10 is the greater) must be
converted into arc at the rate of 20",833 for one revolution. When the
reading is negative, it must be added to the reading at coincidence with
the fixed wire. The value of the revolutions was obtained in 1833 by
observing a pretty well-defined aperture on Grantchester steeple (under the
meridian mark of the transit) with the micrometer wire successively at the
revolutions 0 and 20, and reading the circle microscopes.
The times given in column 10 are generally for the observations of
Polaris and 5 Ursaj Minoris (whose path within the field of view is A'ery
much more curved than that of any other star). This time being reduced
to time by Hardy (the transit-clock) by the comparisons at the bottom of
the right-hand page, and compared with the observed time of transit, gives
the distance in time of the star from the meridian : by means of which,
with special tables, the correction to the meridian is easily found. When
no time is given for these stars, it is to be understood that they were
observed on the meridian. When any star or planet whose declination is
considerable is observed at a distance from the middle wire, a correction is
generally applied for the curvature of its path. This is calculated by di-
viding ten times the log secant of the distance from the middle wire
(considering the intervals of the wires 4' each, the distance of the micro-
meter-comb from the 5th wire as 4', and the distance of the edge of the
field from the 5th wire as 7') by the difference of log cos N.P.D. as
given for 10" in Callet's Logarithms: or it is calculated by the proper
formula.
XXVI INTRODUCTION.
Column 11 contains the correction for the micrometer reading (which is
always placed before any other) and the correction for curvature of path :
it contains also (for the Sun, Moon, and Planets whose polar distance varies)
the correction depending on the difference between the time at which the
body passed the middle wire and the time at which it was observed. Of
the calculations for the Sun and Planets, no explanation is necessary. But
the rapid change of the Moon's N.P.D. makes it requisite to shew that due
accuracy has been preserved. The calculation is thus made. As the Moon
is commonly observed at the instant of passing some one of the vertical
wires, or her distance from the middle wire at the time of observation is
fioted in terms of the interval between two wires, a knowledge of the in-
tervals of the wires is necessary. By transits of six stars, the interval was
found to be nearly 16\6 for equatoreal stars. The time occupied by the
Moon in passing from one to another is therefore 16\6 x F nearly, where
F is the lunar factor in the Bologna Ephemeris : and hence the log varia-
tion of the Moon's N.P.D. in passing from one wire to the next is
= 8,44196 + log i^ + log variation in 10™ (the last term of which is taken
from the Nautical Almanac). The circle reading thus corrected is therefore the
reading corresponding to the body's passage over the middle vertical wire.
When both limbs of the Moon are observed, one of them in general is
a little defective from want of illumination. A numerical correction is thus
investigated. The Moon's place, on a common celestial globe, is brought
to the horizon at the meridian : and the number of degrees by which the
Sun's place is then above or below the horizon is measured. In the former
case the reading for the S.L. requires the correction, + Moon's semidiameter
X versed sine of Sun's elevation : in the latter, the reading for the N.L.
requires the correction, — Moon's semidiameter x versed sine of Sun's depres-
sion. This supposes the Moon to be gibbous, as is almost always true in
these observations.
Another correction is applied to every observation (not explicitly stated
in any of the columns) depending on the consti'uction of the micrometer
microscopes. When two adjacent divisions are viewed with a microscope,
five turns of the micrometer ought to carry the micrometer wire from the

adjustment with accuracy, both because it is one of much deUcacy, and be-
cause it is continually altered by the expansion or contraction of the circle.
From time to time therefore (especially when there has been a considerable
change of temperature) the observer carefully reads the micrometer of each
microscope for the divisions which happen to be on both sides of the
center of the field. The excess of the seconds read for that division which
is commonly registered, over the seconds read for the next division on the
negative side (with reference to the micrometer reading), is the error which
would be committed in excess (if not corrected), supposing the reading of
that microscope to be nearly 5'. For a smaller reading, the eiTor would
be smaller in the same proportion. The sum of the excesses for all the
microscopes is therefore the error in excess of the sum of the microscope
, readings (if not corrected), supposing the readings nearly 5', and therefore
the sum of the microscope readings, before being divided by 6, requires,
for correction, that sum of excesses with its sign changed: the whole to be
taken if the reading is nearly 5', but to be diminished in proportion if the
reading is smaller. The sum of the excesses with changed sign is given
at the bottom of the right-hand page as the " Correction for Runs."

Column 12 contains the mean of the microscopes corrected for the
three quantities just described: and it is therefore the reading of the circle
supposing the microscopes to have been in accurate adjustment for runs,
and supposing the body to have been observed with the fixed wire when
it passed the middle vertical wire; or (for Polaris and S U. Minoris) at
the time of true transit.
Column 13 contains the initial of the observer's name. The observations
marked A are by myself, those marked G by Mr Glaisher, and those
marked J.G by his brother, Mr John Glaisher.
Column 1 on the right-hand page contains the seconds of the zenith
point as determined from each star which has been observed at the same
passage by reflexion and directly. The mean between the two readings in
those positions corresponds to the reading when the telescope is horizontal:
and this altered in the proper direction by 90" gives the reading when the
telescope is vertical. The zenith points thus determined from different stars
ought to agree: their disagreement will be noticed presently. The zenith
point which is adopted for the formation of all the zenith distances is given
at the bottom of the page. It has generally been found by dividing the
stars observed by reflexion and directly into three groups, one comprehending
stars near the zenith, and the others comprehending the stars far from the
zenith north and south respectively: the mean of the zenith points given
by each group is considered as one result, and the mean of the three results
is adopted for the zenith point.
INTRODUCTION. XXXI
Column 2 contains the difference between the reading of the circle for
the object observed and the reading for the zenith point. It is therefore
the zenith distance of the object, on the supposition that the zenith point
is correctly found, and that the circle measures angular distances in the
meridian without error. The negative sign denotes that the object is North
of the Zenith.
The four next columns contain the materials for the calculation of re-
fraction. Column 3 has the height of the barometer as shewn by a cistern
barometer constructed by DoUond and attached to the circle pier: the lower
surface of the mercury is raised by a screw pressing the bag till the light
seen below a brass edge is excluded : and a brass slider is brought to the
upper surface to shut out the light in the same way. Column 4 has the
reading of the thermometer whose bulb is plunged in the cistern of the
barometer.
In an Addendum to the Observations for 1834, it was stated that there
was reason to think that the barometer-reading was too small by 0,1 inch
nearly. This determination was founded upon a number of comparisons,
of which the following is an abstract.
DoUond's barometer was compared immediately with a similar barometer
by Troughton and Simms in the possession of Mr Sheepshanks, and with
a syphon barometer by Robinson in the possession of Professor Miller. The
former of these was compared with Mr Simms' standard barometer : and
with Newman's standard barometer, Daniel's barometer, and Schumacher's
barometer, at the apartments of the Royal Society. The result was, that
DoUond's read less than
Troughton and Simms's by 0,086
Robinson's ,127
Simms' standard ,128
Newman's standard ,112
Daniel's ,065
Schumacher's , ,095
The bore of DoUond's tube is much smaller than either of the others.
e2
XXXll IKTRODUCTION.
In consequence of this determination, the registered height of the ba-
rometer has always been increased by O'^JO for the calculation of refraction.
The height recorded in column 3 is, however, that which is read imme-
diately from the barometer.
Column 5 has the mean of the readings of the two free thermometers.
These thermometers are carried by jointed arms attached to the top of the
circle pier (one at the north and one at the south end), and therefore at
the level (nearly) of the upper limb of the circle. The bottoms of the
thermometer-scales are cut off, so that the bulbs are perfectly free : the
middle of each thermometer-scale is screwed to a piece of tin-plate which
crosses a tube of tin-plate about 4 inches in diameter : and this tube is
carried by the jointed arms. The top of the tube, as well as the bottom,
is protected by a flat disk 6 inches in diameter and 2 inches from the
extremity of the tube. It is presumed that this construction insures the
free passage of air by the thermometer bulb, and that it is well protected
from radiation ; and that the thermometers therefore give the true tem-
perature of the air. The shutters (except the lowest) are always kept open,
and thus there is generally a strong current of air past the thermometers :
no lamp is allowed to burn near them longer than is absolutely necessary.
When the Sun is near the meridian, the thermometers are turned from its
rays by means of the jointed arms. For reading the thermometers, doors
are provided in the sides of the tin tubes. With the view of ascertaining
more certainly the relations of the exterior and interior thermometers, a
thermometer, exactly similar in construction and mounting to those fixed
upon the circle piers, was attached to a moveable stand about 5 feet high
on the N. side of the Observatory, which was kept as far from the building
as could be done without exposing it to the direct rays of the Sun. Before
the commencement, and after the conclusion, of the experiments, the ther-
mometer was compared with those fixed on the pier, and found to give
precisely the same reading. The following is an abstract of the results :

The reading used in the calculation of the refractions is always that of the
interior thermometer.
Column 6 has the refraction, calculated by BesseVs tables in page 538, &c.
of the Tahulte Regiomontance. The form of these tables has been altered
so as to dispense with the necessity of change of signs : and they have
been expanded so as to avoid the necessity of interpolation.
Column 7 contains the parallax. For the Moon, the horizontal equatoreal
parallax is interpolated with second differences from the Nautical Almanac :
it is then altered by the quantity given in the following table (for the
calculation of which see Cambridge Observations, Vol. iv. for 1831, p. 147).

XXXIV INTRODUCTION.
The true parallax is then accurately computed (without assuming the
sine equal to the arc), considering the angle of the vertical = 11'. 12", and
the log radius for Cambridge = log equatoreal radius + 9,9990916. For the
Sun and planets the log horizontal parallax is found by adding 0,9325 to
the ar. comp. log distance: and the true parallaxes are computed with the
same angle of the vertical. These numbers suppose that the proportion of
the Earth's axes is 297 : 298 : and that the Sun's horizontal equatoreal
parallax at mean distance is 8",5776.
Column 8 contains the micrometer reading for the limb of a planet
opposite to that observed with the fixed wire: and column 9 contains the
semi-diameter. The Sun's semi-diameter is taken from the Nautical Al-
manac: the Moon's is interpolated from the Nautical Almanac with second
differences. For the planets, the micrometer reading (treated as has been
described for the micrometer readings in the left-hand page) gives the ap-
parent diameter of the planet in the vertical direction. For Mercury, Mars,
Jupiter, and Saturn, the diameter is merely divided by 2 to obtain the
semi-diameter in column 9- But for Venus it is necessary to take account
of the apparent figure. This is done, when she is horned, by bringing her
geocentric place on a common celestial globe to the zenith, and then by a
quadrant of altitude finding the azimuth of the Sun's geocentric place: its
distance from the East or West point' measures the inclination of the horns
of Venus to the vertical. When she is gibbous, her geocentric place is
brought to the horizon at the meridian, and the Venero-centric place of
the Sun being marked on the globe, its distance from the horizon is the
same as the distance of the highest or lowest point of the illuminated disk
of Venus from the highest or lowest point of her true circular disk. In
both cases, the measured diameter is divided by 1 + cosine of angle so found,
to obtain the semidiameter : and this, or the diflference between this and the
measured quantity (according as the full limb or the imperfect limb has
been observed with the fixed wire) is used for the semidiameter, and is in-
serted in column 9. It is presumed that the determination of the place of
the center by these methods is very much more accurate than if any tabular
semidiameter had been used.
INTRODUCTION. XXXV
Column 10 contains the geocentric N.P.D. of center from each observa-
tion, supposing all the above-mentioned corrections applied, and assuming
the colatitude of the Observatory to be 37" • 47' . 8",28. The negative sign
denotes that the object is below the pole. It must be noticed therefore
that this is the N.P.D. of the center of the object as viewed from the
Earth's center, at the time of passing the middle wire, assuming the adopted
zenith point to be correct, assuming the circle to measure angular distances
correctly, assuming the correctness of the refractions, assuming the correct-
ness of the Moon's semidiameter and of all the parallaxes, and assuming
the colatitude of the Observatory. Most of these quantities require cor-
rection ; and this therefore must not be considered as a final result.
Stars ohserved with the Micrometer, &^c. page 105.
The three observations of Castor given here were made with the mi-
crometer, and are calculated in the usual way.
Vertical diameters of the Sun and Moon, page 106.
These diameters are freed from refraction and parallax (the application
of parallax separately to the two limbs having the same effect as applying
with changed sign the augmentation of semidiameter). For the Moon, when
either limb is imperfect, a correction is applied as above-described. These are,
therefore, true geocentric semidiameters. It has not been thought necessary
to give those of the planets, as they may be taken without subtraction
from column 9, right-hand page, of the Zenith Distances ohserved, &c.
Mean North Polar Distances of Stars, &p. page 108 to 118.
These mean N.P.D. to the beginning of the year are reduced from the
apparent N.P.D. in column 10, right-hand page, of the Zenith Distances
observed, &c. by the following methods. For the stars included in the list
of the Nautical Almanac, the corrections are found by subtracting the mean
place in that work from the apparent place (noticing that the corrections
thus obtained are of declination, whereas the elements used in this volume
are always N.P.D.) For other stars, included in the catalogue of the Royal
Astronomical Society, the corrections (with the same notice) are calculated
by the formula Aa' + BV + Cd + Dd' . For stars not included in that
catalogue, the correction (also for apparent declination) is calculated by
XXXVl INTRODUCTION.
the formula A x (N°. log = 9,6375) x sin N.P.D. - ^ . sin M . cos N.P.D.
+ B.COS JR. cos N.P.D. -f C x (N°. log = 1,3020) xcos JR- I). sin JR. Log A,
log B, log C, and log D, are taken from the Nautical Almanac. The results
included in brackets are those of which no use is made in taking the mean.
The results of each star, as observed directly or by reflexion, above the
pole or below the pole, are kept in separate groups: because one comparison
indicates a discordance of a very remarkable kind ; and the other indicates
any error in the assumed colatitude.
The nature of the discordance above alluded to is this. The zenith point
determined by a northern star is generally greater than that determined by
a southern star : or if a mean zenith point be determined as has been de-
scribed, the N.P.D. of a star N. of the zenith and above the pole is generally
greater by direct observation than by reflexion (if below the pole, it is less),
while the N.P.D. of a star S. of the zenith is generally less by direct ob-
servation than by reflexion.
For a more detailed statement, and for an account of the difficulties
which I find in offering any explanation, I beg to refer to the volume for
1833. I shall only remark here, that I am as little able as ever to offer
a conjecture as to its cause.
As the only circumstance that I can consider likely to affect this dis-
cordance is the position of the telescope on the circle, I thought it best (as
in 1833 and 1834) to group together all the observations in each position of
the telescope. Then (as the adopted zenith point is determined by a method,
already described, which is likely to give results related at all times to the
state of the circle in a tolerably uniform manner), the amount of the dis-
cordance for any star when observed both directly and by reflection on any
night would be found, with reference to a determinate method of obtaining
the zenith point, by subtracting the direct zenith distance from the reflected
zenith distance, or the direct mean N.P.D. from the reflected mean N.P.D.
And the mean of the numbers found for each star, in one position of the
telescope, would shew more accurately the amount of the discordance for
that particular zenith distance. The following tables, therefore, have been
formed by subtracting algebraically (considering N.P.D. below the pole as
negative) the N.P.D. given by direct observation from the N.P.D. given
INTROBUCTION.

by reflection at the same transit, and taking the mean of all the differences
so found.

and Reflected Observations.
I^The N.P.D. is considered negative when the Star is below the Pole, and the Difference is
taken with a regard to the Algebraic Signs.]

A line of abscissae being taken on which the zenith distances were
laid down, the values of D ~ B were used as ordinates to determine the
position of points : and among these points I drew by hand a curve,
endeavouring to make its proximity to any point depend (as well as in
a simple curve could be done) upon the number of observations by which
that point was determined. The ordinates of this curve were then mea-
sured, at the points where they would be most convenient for use; and
half these ordinates were considered to be the correction for the N.P.D., to
be applied with one sign to the direct determinations and with the opposite
sign to the reflection-determinations. This operation was performed for both
positions of the telescope : but it appeared that the same numbers would
extremely well represent the corrections for both positions.
In the Addendum to the Volume for 1834, it was remarked, that (in
consequence of the error in the refractions depending on the error of the
barometer) the colatitude ought to be increased by 0",15. This correction

Right Ascensions and North Polar Distances of the centers of the Sun,
Moon, and Planets, observed in the year 1835, with the Greenwich Mean
Solar Time of Observation, and compared with the places interpolated from
the Nautical Almanac or the Meridian Ephemeris of the Roycd Astronomical
Society, page 124 to 136.
In all cases the Right Ascensions of the planet's limb (if one limb only
was observed) have been taken from the column Appfirent M. from the
observation in the Transits as observed, <|c., and have been corrected for
the semidiameter in the manner that will be explained for each. If both
limbs were observed, the right ascension of the' center is taken from the
same column, and is not altered in any manner. The Geocentric N.P.D.
INTRODUCTION. xli
of the Center in the Zenith Distances observed, <§c. have been corrected by
means of the table just given.
The Greenwich Mean Solar Time is found from the Right Ascension
by adding the next preceding Mean Time of Transit of the first point of
Aries, from the Nautical Almanac, (diminished by 23',48, because Cambridge
is 23',54 East of Greenwich) to the equivalent, in Solar Time, of the Sidereal
Time representing the Right Ascension.
The right ascension of the Sun's center, when one limb only has been
observed, is formed by applying to the observed right ascension of the
limb, the sidereal time occupied by the transit of the semidiameter as
given in the Nautical Almanac. From this right ascension of the center,
the Greenwich Mean Solar Time is deduced by the method just explained.
For the days on which the N.P.D. was observed and the ^R not observed,
the Mean Solar Time is found by the same process, using the M. for ap-
parent noon of the Nautical Almanac, corrected for difference of longitude.
The tabular places both in M. and in N.P.D. are taken from the places at
apparent noon in the Nautical Almanac, applying (with the sign changed)
Y^g of the hourly variation. It is always to be understood that both limbs
are observed, (the 1st and 2nd with the transit and the N. and S. with the
circle) unless one limb is specified in the column of Limb observed.
For the Moon's yR, the Greenwich Mean Solar Time is always the time
of transit of the limb observed, the name of which is given in the second
column. The M. is the M. of the center, which is deduced from that of
the limb (in the column of Apparent iR from the Observation in the

being interpolated with second differences from the Nautical Almanac, and
the declination at transit being taken from the section of Moon-culminating
Stars in the same. The tabular M. of the center has been found by taking
the yR of limb from the section of Moon-culminating Stars in the Nautical
Almanac, applying with sign changed j^ of the difference for 1" of longi-

therefore, in fact, the observed M of the limb with the M of the limb
given in the Nautical Almanac (the same correction for semidiameter in
jR being applied to both) : but it has been thought that the exhibition in
the form of M of the center would be more convenient for further uses.
On three or four occasions the tabular M of the center has been computed
by second diiferences from the hourly ephemeris in the Nautical Almanac :
the greatest difference between the M of the center thus directly computed
and that indirectly computed from the process above described is 0',03.
When a limb was observed whose M was not given in the Moon-culminating
Stars of the Nautical Almanac, the tabular M of the center for that time
is computed with second differences from the hourly ephemeris.
The Greenwich Mean Solar Time for the observation in N.P.D. or for
the transit of the center, is found by applying to the time for the limb,
the solar equivalent for the duration of transit of semidiameter in the
Nautical Almanac. On those days in which the transit was not observed,
the JR of the limb in the Nautical Almanac has been altered for the dura-
tion of transit of semidiameter, and the Greenwich Mean Solar Time
calculated from it in the usual way. With this the tabular N.P.D. has
been computed with second differences from the hourly ephemeris of the
Nautical Almanac.
The apparent N.P.D. of the Moon's center, besides the correction for
the discordance of Zenith points, is affected with another correction which
in every other case is insensible. The N.P.D. in the Zenith Distances ob-
served, &jc. is that for the time of passing the middle wire : this does not
coincide with the meridian : and a correction is necessary for the Moon's
change of N.P.D. By numerous transits of several principal stars observed
with the circle and Molyneux, and referred by comparison of clocks to
Hardy, its errors of position at various polar distances were found. It was
found that these might be represented with sufficient accuracy by assuming
the transit over the middle wire, from January 1 to July 9, to be too late
by 5',5; and from July 10 to the end of the year, to be too late by &,0.
The variation of N.P.D., in the interval between passing the middle
wire of the telescope and passing the meridian, is calculated with these
INTRODUCTION.
xUii
numbers and with the variations for 10" in the hourly ephemeris of the
Nautical Almanac; and this correction is applied to the observed N.P.D.
The columns of Errors of Tables contain the effects on the Errors which
would be produced if the Moon's tabular semidiameter were increased by
_J^ part: those for the N.P.D. contain also the effect of increasing the
tabular parallax by j^ part, and the effect of supposing the Earth spherical
with the same equatoreal radius (to give the reader the power of easily alter-
ing the proportion of axes, viz. 297 : 298, with which the parallaxes have
been computed). For the formation of the last-mentioned column, the
parallax has always been calculated on both suppositions.
For Mercury, Venus, and Mars, the Greenwich Mean Solar Time is
the time of transit of the limb, but the M is the jr of the center, found
from that of the limb by applying the semidiameter in j^ which is given
in the Meridian Ephemeris circulated by the Royal Astronomical Society.
As the semidiameter used for correcting the M is calculated from an as-
sumed semidiameter, while that used for the N.P.D. is inferred from each
observation, it is thought proper to mention the limb observed in M, but
not that observed with the fixed wire in N.P.D.
For all the other planets, the Greenwich Mean Solar Time is the time
of transit of the center.
The tabular M and N.P.D. have been computed, as far as possible,
from the M and N.P.D. in the Meridian Ephemeris, applying j^ of the
hourly variation with sign changed. As this work is calculated from the
data of the Nautical Almanac, and under the immediate direction of its
Superintendant, it is considered to be in all cases an accurate representation
of the results of the Nautical Almanac. In a few instances, where observa-
tions have been made beyond the limits of the Meridian Ephemeris, the
tabular places have been calculated, with second differences, from the daily
ephemeris in the Nautical Almanac.
As the accurate ephemeris of the small planets in the Nautical Almanac
extends only to a certain time before and after opposition, the tabular
xliv INTRODUCTION.
place cannot be accurately given beyond these limits, and therefore no
attempt is made to exhibit it collaterally with the observed place.
The reductions for Halley's Comet are made in the same manner, in
all respects, as those for the planets. At the time of sending the observa-
tions to press (in the sections Transits observed, 8f,c. and Zenith Distances
observed, &f:.) there existed no accurate means of computing the parallax
of the Comet. Since that time, an ephemeris (computed on very approxi-
mate elements, vmaffected with perturbation) has been circulated by the
Superintendant of the Nautical Almanac, and from this the log. distance
has been taken for the computation of parallax : which is applied to form
the Apparent N.P.D. from observations given here. The Tabular R.A. and
Tabular N.P.D. are interpolated from the same ephemeris. The elements
of the orbit assumed in the ephemeris are the following :

It must be borne in mind, that all the errors of tables in M are affected
by any error in the assumed M of the fundamental stars.
Comparisons of Clocks and Chronometers, pages 138 and 139-
The comparisons of the clocks with the sidereal chronometer U, are made
by merely estimating the second and fraction of a second indicated by one
at the beat of the other.
The comparisons here given are necessary for the reduction of the ob-
servations with the equatoreal and the detached telescopes.
Observations of the Elongation in Right Ascension of Jupiter s Fourth
Satellite, with the Equatoreal and the Clock Graham, page 142.
INTRODUCTION. xlv
A description of the Equatoreal with which these observations were
made, may be found in the Observations of 1832. It will be sufficient for
the present purpose to remark, that in all observations it is considered as
an instrument which is essentially incapable of giving absolute places with
accuracy, but which is capable of giving differences either of M or of
declination with considerable accuracy.
The screws for adjusting the Equatoreal had not been touched since the
observations of 1833. The observations of 1833 and 1834 appeared to shew
that the adjustments were not liable to change : and as a small error in
adjustment produces no sensible error in the results of comparative observa-
tion, it has not been thought worth while to examine the adjustments in
1835.
In observing Jupiter and his 4th satellite, the declination circle is never
clamped, but as soon as the transit of one object is finished, the circle is
moved by hand, so that the transit of the other may be observed on the
same parts of the wires as nearly as possible. When the observation of
both objects is completed, the hour circle is released from its clamp, and
the instrument is turned round the polar axis to prepare it for another
observation of both objects. During the course of each double observation
the hour circle is held by its clamp, and is not touched by the observer :
and the eye-piece is not moved in its sliding frame. The observations
included between any two horizontal black lines are those made with
unaltered position of the hour circle.
At the termination of the observations, the hour angle of the Equatoreal
is noted : from which the hour angle at the middle of the observations is
found. The difference of the polar distance of the planet and satellite is
also roughly observed. The whole of these observations are made by Mr
Glaisher.
The effect of refraction on the apparent M of each body at passing the
same wire is computed, supposing that vertical refraction may be repre-
sented by 57" X tan zen. dist. The difference between the computed refractions
is to be applied, with the proper sign, to the mean of the observed differences

of right ascension (being additive when the N.P.D. of the following body
is the greater and the objects are East of the meridian). The effect of
refraction, in the present instance, is insensible.
The difference of right ascension, so corrected, is multiplied by a factor
depending on the motion of the Jovial system in M (which factor is
greater than 1 when the motion is retrograde and less than 1 when the
motion is direct). This factor is the reciprocal of the factor used for com-
pleting imperfect transits, under similar circumstances.
The times by Graham are converted into times by Hardy, by means
of the table of comparisons of Clocks and Chronometers : the clock error
and clock rate are applied to Hardy, and the Greenwich Mean Solar Time
found, in the same manner as for the meridional observations of Planets.
These observations were made in the commencement of the year 1836,
and ought in strictness to have been retained for a future volume. But
as the direction of the Observatory has since that time been changed, it
was thought better to preserve them in the volume to which they are
more closely related, both in similarity of plan and in proximity of time.
Observations of a Spot on Jupiter's Disk, with the Eqiiatoreal, p. 144.
These observations were made with the view of obtaining data for the
time of rotation of Jupiter. The spot observed was one of two on the
lower edge of the lower broad belt (as seen with an inverting telescope) : it
is the same on which observations were made in 1834 (see Vol, vii. p. 188,
&c.).
As the axis of Jupiter was sensibly inclined to the meridian, these ob-
servations do not give accurately the position of the spot with regard to
its arc of rotation ; but the correction required would be so nearly the
same in all the observations, that for determining the periodic time this
consideration may be safely neglected.
Differences of N.P.D. of Mars and Stars near him, observed with the

followed. The stars compared with Mars are principally those of the
ephemeris contained in the Nautical Almanac 1835, p. 480, &c.
In some of the comparisons, the objects which were compared passed in
the same field of view, and could be observed with the micrometer wire
(the declination circle being clamped). The value used for the micrometer
divisions is that given in the Observations for 1833, p. 156, namely,
l'^ = 33",429. The wire of micrometer a is pretty exactly parallel to the
fixed wire, and the reading of the micrometer a at coincidence was found
in December 1834 (confirmed by observations in March 1835) to be 0'',054.
The wire of micrometer b is not quite parallel to the fixed wire: its reading
at coincidence, as found in December 1834 (and confirmed in March 1835),
is O^lOO at the first wire (graduated face of circle East), 0',085 at the
center wire, and O^OOO at the fifth wire. The micrometer a is that whose
graduated head is upwards, and which has the greatest range in the upper
part of the field, when tlie graduated face is East.
In other comparisons, the objects are too widely separated in N.P.D. to
pass in the same field : and then it is necessary to move the telescope and
attached declination-circle, and to read the divisions of the declination-circle
with the two microscopes A and B, carried by arms attached to the frame
of the polar axis.
In the volume of 1834, p. xlix. &c. I have fully stated the nature of
the examination to which the divisions of the declination-circle have been
subjected, with a table of the errors of 96 principal divisions (page Iv),
and a description of the method used for the errors of subordinate divisions
employed in the series of observations there alluded to. For the subordinate
divisions employed in the present series the same method was used : con-
sisting merely of a measurement, by means of the micrometers in the mi-
croscopes A and B, of each of the 45 intervals between two of the principal
divisions : from which, as the errors of the first and the last are known,
those of the intermediate divisions are easily found. The opposite sets of
divisions were examined at the same time, one with A and the other with
B. The operation was repeated: and the mean of the results of the two
operations was adopted. The greatest discordance in the two results for a

lowing are the resulting corrections to be applied to the readings of the circle.

INTRODUCTION. xlix
The whole correction for A's run of 5', in the arc 240" — 243° . 45', ap-
peared to be - 4",5, and in the arc 116". 1.5'— 120", it appeared to be -3",5.
That for J?'s run, in the arc 60" — 63" . 45', appeared to be - 2",0, and in
the arc 296". 15' — 300°, it appeared to be — 0",5. These are the quantities
used in computing the corrections in the observations of Mars, &c.
Little explanation is necessary for the rest of the calculations and
results with regard to Mars. The times are converted by the same suc-
cessive steps as for Jupiter's fourth satellite: the place of INIars is calculated
with second differences from the daily ephemeris in the Nautical Almanac:
the refraction is computed on the same supposition as for Jupiter's fourth
satellite: the parallax with the assumed horizontal equatoreal parallax from
the Nautical Almanac, and with the supposition that it varies as sin. distance
from geocentric zenith (the formulas used for the two latter being easily
found in parts of the spherical triangles formed by drawing an arc of great
circle from the astronomical or geocentric zenith perpendicular to the
meridian passing through the body observed). The form in which the
results are exhibited will enable the reader to correct them for an alteration
in the assumed place of the stars compared, and in the inagnitude of the
parallax. As this course of observations is in every respect a continuation
of that of 1834, the numeration of the series is continued.
Might Ascensio7is and North Polar Distances of Halleys Comet and Stars,
observed with the Eqtiatoreal and the clock Graham, 1835 and 1836, p. 170.
In the observation of Halley's Comet, it appeared necessary to secure,
if possible, both the following objects. First, to effect a series of accurate
comparisons of the Comet with any stars which might be found so near
to it, as to be similarly affected by the errors of adjustment, flexure, and
other defects of an equatoreal. Secondly, to observe well-known stars whose
distance would make the comparison less accurate, but which would give
approximate places of the small stars for their future identification.
For these reasons, it has been thought desirable to deduce from every
transit the apparent M. of the object observed, subject to the index-
error of the hour circle, the error of the clock, and the errors of observation,
of adjustment, those arising from flexure, &;c. The latter, though sensible,
are so small, and the clock rate is so small, that the combined error of the
I INTRODUCTION.
hour circle and the clock, deduced from the well-known stars, will apply-
nearly for other positions of the instrument in the observations of the
Comet and small stars, at least nearly enough to give very approximate
places. The most accurate places of the Comet must rest upon the com-
parisons made in unvaried positions of the instrument : nearly the whole
of which will require future meridional observations of the small stars.
The whole of the observations recorded here were made by Mr Glaisher.
The whole were also made with the graduated face of the declination-circle
West. By this expression it is not to be understood that the graduated face
was turned towards the West when the object observed was more than six
hours from the upper meridian, but that the position of the instrument was
related to the place of the object in the same manner as it would have been
if the body had been on the meridian above the pole, and if the graduated
face had then been West.
The first column on the left-hand page, in the section of Right Ascen-
sions, contains the day of the month. The second column contains the
number of the series (where by a series, as in the observations of Mars, is
meant the set of observations made without varying the position of the polar
axis). To prevent the possibility of confusing the series of Comet-obser-
vations with those of the observations of Mars, the numeration is here
begun from 100. Two or three series have been rejected (a wrong object
having been observed), and the numeration is therefore a little irregular.
The third column contains the name of the object : the small stars being
distinguished by letters. The letter M denotes that the object is observed
with a micrometer wire.
The fourth column contains the time of entrance (as shewn by the clock
Graham) into the field. This mode of observation was employed only when
the Comet was so faint as to bear no illumination in the field, or before
thick wires had been mounted in the wire-frame. The observation of
entrance was by no means accurate, as, in entering, the body emerged from
behind the comb, and its time would therefore be different according as it
emerged from a tooth or from a hollow. The error, however, was probably
not greater than that to which every observation of the Comet was liable
before its disk was seen pretty well defined.
INTRODUCTION. U
The five following columns contain the times of passing the five transit-
wires of the Equatoreal. At the commencement of the observations the
wires mounted in the wire-frame were of cobweb and very delicate: their
position with regard to the equator was very well adjusted. It soon ap-
peared desirable to change these for thicker wires : and the latter were
mounted on October 13, and were used for several days without adjust-
ment. On examination it was found that their position was very erroneous.
The transits were not affected by this error when the objects were ob-
served on or very near to the wire parallel to the equator : and it is
always to be understood that this condition holds with regard to those
observations in which the micrometer was not read : such being the in-
variable practice of the observer. For correction of the transits observed
at a distance from the equatoreal wire, it was remarked that (as nearly as
could be observed) the error of the meridional wire, at the distance of 10 revo-
lutions of the micrometer from the equatoreal wire, was ith of an interval
of wires, and that the objects whose N.P.D. was greater than that of the
equatoreal wire, passed the wires too early. The correction corresponding to
this error has accordingly been applied from Oct. 17 to Oct. 19 (both days
included). On Oct. 20 the position of the wires was accurately adjusted.
The tenth column contains the time of departure from the field. The
boundary of the field of view, on the departing side, is a straight line,
much better defined than that on the entering side : and the observations
of departure are much more accurate than those of entrance.
The eleventh column contains the correction for imperfect transits. The
mean of the five wires is assumed to coincide with the 3d wire. This
is not accurately true : but it is nearly enough true for the Comet ob-
servations. The distances from the middle wire (for an equatoreal star)
used in the reductions from Sept. 2 to Jan. 10, are the following :
s
Entrance + 51,54
1 Wire + 25,79
2 + 12,91
4. - 13,22
5 -26,05
Departure — 67,97
lii INTRODUCTION.
It has been mentioned, that in the month of October thicker wires
were inserted; but they were fixed as nearly as possible in the same
notches as the old ones, and it does not appear necessary to make any
change in the assumed distances of the wires.
In the month of January 1836, a new system of fine wires was
mounted, and the following are the intervals used for their reduction :
s
Entrance + 49,55
1 Wire + 20,98
2 + 10,33
4 - 10,55
5 - 21,11
Departure — 69,96
It is probable that the assumed intervals, for both systems of wires,
are not very accurate, but there is no doubt that they are much more
accurate than any Comet-observations. In the computations for the Comet,
allowance is made for the Comet's motion in M.
The twelfth column contains the correction for the position of the
wires. This is computed on the principle already described.
The first column on the right-hand page contains the time of transit
over the middle wire, as inferred from the mean of all the observed
passages affected with the corrections in the two last-mentioned columns.
The second column contains the reading of the hour-circle-pointer.
This is merely a brass index touching a circle roughly divided into
minutes of time. It is not very firmly fixed: and some confusion was
introduced in a portion of the observations by its disturbance. This,
however, is completely removed in the printed sheets.
The third and fourth columns contain the readings of the microscope-
micrometers of the hour circle. These are fixed so as to read opposite
divisions. The band to which their view is directed is divided into spaces
of 20', and these are subdivided by the micrometer reading to 0',1. One
turn of the micrometer corresponds to 4' on the limb. In some of the
INTRODUCTION. liii
observations the microscopes were not read, or their readings merely guessed
at. As in all these instances the observations are strictly differential, the
omission is of no importance. The hour-circle-reading is the hour-angle
East of the Meridian.
The fifth column contains the Apparent Right Ascension, found by
adding the reading of the Hour Circle to the Clock Time of Transit.
It is of course subject to Instrumental and Clock Errors, as well as to
refraction and parallax.
The sixth column contains the approximate N.P.D., which is necessary
for the calculation of the two following columns.
*&
The scA'enth column contains the refraction in M. It is generally com-
puted on the supposition that the vertical refraction will be represented
with sufficient accuracy for differential observations by the formula 57" x
tan. zen. dist. On the 15th and 18th of November, however, not only the
refraction but also the difference of refraction being considerable, it was
thought necessary to calculate with much greater attention to accuracy.
The following is the niethod used on those days. The reading of the
hour circle is increased by 10'; which appears, from comparing several
resulting right ascensions (corrected for clock error) with tabular right
ascensions, to be nearly the index error. The true apparent hour angle
is thus obtained. The apparent N.P.D. given by the declination-circle is
corrected very approximately for the index error of the declination-circle,
and thus a true apparent N.P.D. is obtained. With these values and the
colatitude 37° . 47' the apparent zenith-distance is computed. With this,
log a is taken from Bessel's tables of refraction : or when the zenith-distance
is beyond the limits of his first table, log a is found from his supple-
mentary table by the formula log a — log refraction + log cotan zen. dist.
57
The value of log a thus found is used instead of log — in the calculation
X o
of refractions by the usual formula.
The refraction is computed for the fundamental stars whose observation
was intended to give information as to the index-error, &c., of the , instru-
ment. It is also computed for the Comet when it has appeared probable
h
liv
INTRODUCTION.
that the absolute instrumental determinations may be needed. For strictly
difFerential observations it has been computed only when the difference of
the refractions was sensible.
The eighth column contains the Comet's parallax in M. This is com-
puted supposing the vertical parallax to be proportional to the sin. zen.
dist., and taking the log. horizontal equatoreal parallax from the formula
0,9334 + ar. comp. log. Comet's distance : the log. distance being taken from
the Ephemeris dated Dec. 30, 1835, circulated by the Superintendant of
the Nautical Almanac.
The ninth column contains the apparent right ascension of every object
observed, subject to instrumental error and clock error, and in certain in-
stances to the omission of refraction, but always corrected for parallax. It
is formed by applying the numbers in columns 7 and 8 to those in
column 5.
The arrangement of the section of North Polar Distances of Halley's
Comet, 8ff. proceeds upon the same general principles as that of the section
of Right Ascensions, with this difference only, that the refraction in N.P.D.
is computed in every instance. The following explanation of the different
columns will probably be sufficient.
The first, second, and third columns give the day, the number of the
series, and the name of the object, in the same manner as in the M.
The series of observations of N.P.D. sometimes correspond with those of
M and sometimes do not. The letter M denotes that the object has been
observed with the micrometer wire.
The fourth column contains the reading of the fixed pointer. The
division indicated by this is supposed to be the same as that read by
Microscope A. There appears reason to think that between Oct. 24 and
Oct. 26 the pointer was disturbed so as to make its reading in a given
position of the circle 5' greater than before. The only error which this
change would introduce would be that the corrections for the wrong di-
visions would be used : but as there is no remarkable change between the
INTRODUCTION. Iv
corrections for adjacent divisions in the arc of the circle employed here,
this is of small importance.
The readings of the microscopes in columns 5 and 8 require no ex-
planation. The corrections for runs in columns 7 and 10 are computed
on the supposition that the error of run of A was + 4",9, and that of
B — 0",2, in the five-minute spaces.
Columns 6 and 9 contain the errors of division of the circle. The
methods by which the errors of division of 96 fundamental points were
found, and the results for these points, are fully explained in the Intro-
duction to the Volume for 1834. These 96 determinations, it is to be
observed, are assumed as foundations for every succeeding investigation of
the errors. In the Introduction to the Volume for 1834, and in the pre-
ceding part of this Introduction, will be found a description of the method
by which the errors of individual points were found from the 96 funda-
mental points, for the observations of Mars. It consisted in merely running
over every space with the microscope-micrometer. To avoid the accumu-
lation of possible errors thus produced, and to diminish the labour of the
process, the following method was now used. Two microscopes were con-
structed under my directions by Mr Simms, of nearly the same length
as the micrometer-microscopes, but so small that they could be placed side
by side, to view two divisions separated by 15 spaces or I^.IS'. They
are, in fact, included in the same prismatic tube. One of these has a
fixed X wire : the other has one fixed x wire and one similar wire moved
by a micrometer. This double microscope is fixed firmly to the pillars of
the instrument, and in the first place it is used to trisect the spaces of
3° . 45', by spaning the three arcs of 1° .15': one division being placed
under the fixed wire of one microscope, and the moveable wire of the
other being then placed upon the other division and its micrometer being
read. The value of the revolutions being found, the difference between
the successive spaces of 1*'.15' and consequently the error of each of these
divisions is easily and accurately found. Then the microscope which has
one fixed and one moveable wire is used alone ; the wires being placed
nearly 5' apart, and a division being brought to the fixed wire, the
micrometer-wire is placed on the next division. In this manner the error
A2

INTRODUCTION.
of each of the divisions is found with the accumulation which belongs to
an arc of 15 spaces only instead of 45, as in the method previously used :
and with greater ease and accuracy in every individual measure. The
errors being thus found, and their signs changed, and 80" added to
make them all positive (as before), the following table of corrections is
formed.

It will be seen that a small part of the arc examined here had also
been examined in the former method for the observations of Mars at
opposition : and near the middle of the arc of 3" . 45' the discordance is
very sensible. This arises entirely, without doubt, from the accumulation
of errors in the former method. The printing of the Volume had how-
ever proceeded too far, when the second examination was made, to enable
me to avail myself of the more correct determinations.
The eleventh and twelfth columns have the same meaning as in the
Observations of Mars, &c. : and the thirteenth column contains the equi-
valent correction in sexagesimal divisions. One revolution of the micrometer
is always considered = 33",429 ; and the readings at coincidence are sup-
posed to be as follows : •»

The fourteenth column contains the correction for the position of the
wires, which between Oct. 10 and^ Oct, 21 (as already mentioned) were
misplaced in such a direction that a star passed apparently above the
wire before it reached the center, and below it afterwards. It appeared
that the following corrections were necessary to the observed polar distance :
When the observation was made at the 1st wire, - 14",5
2d - 7",2
4th + 7",2
5th + 14",5.
Before the observations of Oct. 21 the wires were well adjusted.
The first column on the right hand page contains the circle reading
as affected with the corrections for error of divisions, error of runs,
micrometer reading, and position of wires, and diminished by 180°. This
quantity is always near to the polar distance of the body observed (the
face of the circle having been West during the whole suite of obser-
vations). In a few instances the circle-microscopes have not been read,
and no quantity can be set down for the polar distance.
The second column contains the approximate hour-angle, which is
necessary for the calculation of the two next columns.
INTRODUCTION. Ixiii
The third column contains the refraction in N.P.D. This is always
computed on the supposition that the vertical refraction = 57" x tan zen.
dist, except on Nov. 15 and 18, when instead of 57" a different multi-
plier has been vised for every different calculation, as has been already
described in speaking of the Right Ascensions.
The fourth column contains the parallax in N.P.D. The log. horizontal
equatoreal parallax has been fovmd from the log. dist. in Mr Stratford's
Ephemeris, dated Dec. 30, 1835, and the log. hor. par. for Cambridge is
found by diminishing this by ,0009.
With regard to the formula and tables used for the computation of
extrameridional refraction and parallax from the erection of the equatoreal,
the following explanation will be sufficient. Join P the pole with S the
place of the celestial body, and from Z the astronomical zenith draw ZQ,
perpendicular to PS. Then, if vertical refraction = A . tan ZS, the refrac-
tion in iR >
_ A tnn 7^ .in 9 ^ - A ^an ZQ A tan ZQ
- ^^ . wn Z.O . o . ^.^ p^ j^ . ^.^ pg ^^^ Q^ - 15- sin PS. cos (PS ±PQ)'
And the refraction in N.P.D.
= A.tan ZS. cos S = A .tan QS = A . tan {PS ± PQ).
The quantities ZQ and PQ depend only on the colatitude of the place and
the hour angle. Tables being prepared therefore which give log. tan. ZQ
and PQ, with the hour angle for argument, it remains only to substitute
the value of the polar distance in the formula, and the refractions are
easily found.
In like manner for the parallax ; taking Z' the geocentric zenith, and
drawing ZQ perpendicular to PS, the parallax in M
= -^ X sin ZS X sin aS* x -. — =^ = -^J- x ^^^ — ^ .

And the parallax in N.P.D.
= h.p.xsinZAS'xcos*S'=b.p. x cosZQ'.sin Q'»S'=h.p. x cos Z'Q'x sin (Pa^iPQ').

Ixiv INTRODUCTION.
Tables therefore being prepared containing log. sin Z'Q', log cos Z'Q', and
PQ', with the hour angle for argument, the compvitation of the parallaxes
is easy.
The fifth column contains the N.P.D. from the circle affected with
the corrections for refraction and parallax : it is therefore the true N.P.D.
from the observation, subject only to the index error of the circle and
the error in the position of the polar axis. The refraction has been
applied in every instance.
The two following columns contain the times of observation of the
Comet as noted by Graham, and as reduced by the Comparisons to the
time by Hardy. They will facilitate the reduction of the times by Gra-
ham to times by Hardy for the Right Ascensions also. In many instances
the observation in N.P.D. was not made at the middle wire, and the
time for the N.P.D. observation is therefore not the same as that for
observation in JR.
The table of the approximate places of the stars of comparison is
founded upon the observations. The stars for the most part are ano-
nymous and very small; it will be necessary that they should be oberved
with meridional instruments before the Comet-observations can be made
available.
The time by Hardy is converted into Cambridge Sidereal Time, and
this into Greenwich Mean Solar Time, in the usual way. With this, the
Comet's place is interpolated from the Ephemeris so often referred to,
using third differences whenever their effects are sensible. This Ephemeris
is not affected with planetary perturbations nor (it appears) with aberration.
But it will readily be understood that when the stars shall have been
observed and the observations of the previous pages shall be completely
reduced, the comparison of them with places accurately interpolated from
this very approximate Ephemeris will give a series of Normal Places pos-
sessing great accuracy : and that when (as is expected) an Ephemeris
shall be published, comprising the effects of perturbation and aberration,
it will be the work of a few minutes to apply the difference of the two
Ephemerides, either to the interpolated places given here, or to single
INTRODUCTION. Ixv
places of the old Ephemeris comparable with the Normal Places ; and
that, with the factors of errors of elements in the equations of condition,
a series of such equations may immediately be formed, the solution of
which will give, with great accuracy, the whole of the elements of the
Comet's orbit. >
A place has been interpolated from the Ephemeris corresponding to
every observation of the Comet. It is not meant by this that every
observation will be available.
The Transits with the Mural Circle require no explanation. The Phy-
sical Observations comprise every remark made by me, or by Mr Glaisher,
during the visibility of the Comet.
The Eclipses, <|c., of Jupiter's Satellites, and the Occultations of Stars
by the Moon, are arranged in the same manner as in previous years, and
require no particular explanation. The Calculation of the Occultations is
performed in the same manner as in several past years : the method of
calculation is described in the Volumes for 1830 and 1831.
The Meteorological Observations, on June 22 and Sept. 21, were made
in conformity with a plan suggested by Sir J. Herschel, and which, it is
probable, may be extensively followed, and may offer those prospects for
advance of this science which simultaneous observations alone can give.
The observations of Dec. 21 were omitted from mere inadvertence.

Illuminated end of Axis East. Order of Wires, for Stars above the Pole, ABCDEFG.
(a) The intervals of the wires are irregular.
(6) It seems possible that there may be some error in
the IV and VII wires.
(c) The II wire was set down 9,1.
{(1) The right ascension from this transit is evidently
1' too small : it is increased by V in the tables of
Saturn's right ascension, &c., at the end of the ob-
servations.

Illuminated end op Axis East. Order of Wires, for Stars above the Pole, ABCDEFG.
(a) The 4th wire was set down 57,2 : it is altered con-
jecturally. With regard to this and other conjectural
corrections of Pallas and Ceres, it must be remarked
that they are extremely doubtful : the excessive faint-
ness of the planets making it probable that errors of
1' or 2' may have been committed in the actual ob-
servation.
(b) The 2d wire was set down 20,1.
(c) The 4th wire was set down 27,4. Excessively faint.

From July 9, Illuminated end ok Axis West. Order of Wires, for Stars above the Pole, GFEDCBA.
(a) The II wire was set down 27,1: probably a mistake
in writing.
(6) The wires were all set down greater by V, but the
observer found his counting at the end 1' fast on the
clock: all are therefore diminished by 1".
(c) The wires were all set down greater by 1'.

Very cloudy : the last wire a mere guess.
Very cloudy and faint : some wires uncertain.
The II wire was set down 51,5, which is undoubtedly wrong.

(a) Cloudy.
(A) The observer believed that this was 1' too great. The
intervals of wires are too large: it seems likely that
1" has been lost in the middle of the transit, perhaps
after the 3d or 4th wire.
(c) The 2d wire was set down 21,1, which is undoubtedly
wrong. (rf) Rain.
(e) The last wire was set down 33,1, which is undoubtedly
wrong.
(y) a^ Capricorni was not visible.

(a) Cloudy.
(6) Not good.
In consequence of the unsteadiness of the Zenith (c)
Point during January and February, the screws
connecting the telescope with the circle, the
mounting of the object glass, and the screws (</)
fixing the microscope to the pier, were examined
on Feb. 27 and 28 : all appeared quite firm.
The wrong divisions were read with the micro-
scopes: the correction for runs is therefore positive,
corresponding to 22".
No correction for runs.

(c) Without coloured glass.
(d) At the 4'" wire.
le) One-third of an interval after the 4"" wire.
(/) At the 5"" wire.
(g) Observations at the five wires.
(h) After this observation the circle was taken down
and cleaned, and the telescope shifted. It was
found that the micrometer wire was not perfectly
parallel to the fixed wire: and from July 10 to
August 22 the coincidence at the different wires
is found from that at the middle wire by applying
the following quantities: 1" wire, -,025: 2" wire,
-,013: 4"" wire, +,003: S"" wire, +,012: comb,

(n) Very bad. (6) Blur: very bad.
(c) Not good. {d) At the comb: cloudy and bad.
(e) Rather faint and ill defined : the observations were
made about 3' after passing each wire.
{/) Very unsteady and ill defined: impossible to ob-
serve a limb. (g) Bad limbs. (A) Very good.

(P)
The star beautifully divided : I omitted to read
microscope D, but have supplied it by comparing
C + D with the mean of A + B and E + F in other
observations of the same star.
At 5* wire. (m) Unsteady.
Hasty, among dark clouds. (o) At 3'' wire.
Between 5"' wire and comb : heavily clouded : ob-
servations hurried : limb very faint. (q) Good.

(a) At the five wires: both limbs so nearly full that
the correction is insensible.
(6) Observed at the five wires. About 2° of the S.L.
was not illuminated, and the correction +0",56 is
therefore applied,
(c) Faint.
{dt) Doubtful observation at 5"" wire: the correction
for change of N.P.D. is +0",05, and that for curv-
ature of path + 0",22.
(e) Great undulatory motion.
(/) Not good.
is) Very faint : at 5'^ wire : the correction for change
of N.P.D. and curvature of path nearly destroy
each other.

(a) Very great motion. (6) Blazing.
(c) Not good.
(d) Faint and doubtful. (e) Cloudy,
(y) At 4"" and 5* wires : scarcely visible : observations
far from good. (The limb appears to have been
so faint that the observer was mistaken as to the
direction in which the change of N.P.D. took
place.)
(g') Observed at the 5"" wire and comb.
{h) At 5"" wire: the change of N.P.D. insensible:
faint and unsatisfactory.
Very unsteady.
Between 5"' wire and comb: the correction for
change of N.P.D. is -0",66, and that for curv-
ature of path is +0",31. (/) Very good.
(m) At 4'* and 5"* wires: not good.

(a) Pretty good,
(ft) A blur.
(c) After this observation, the parallelism of the mi-
crometer wire with the fixed wire was adjusted,
and the reading at coincidence may now be con-
sidered to be the same at every part.
(d) Very good.
(e) Extremely faint.
If) Very bad: the observations made at the 3* and
5th wires: both are corrected for the change of
declination in I6'.
(g-) Observed at the five wires: very faint: all the
observations doubtful.
(A) Too much wind : not good.

(a) A bad blur : the direct observation at the 5"" wire.
(b) Observations at the five wires: great motion.
(c) Very good. (rf) At 4"' wire,
(e) Observations at the five wires.
(,/■) At 5"" wire and comb : difficult, (g) Not very good.
(h) Observations at the 5'" wire and comb: the S.L.
has the correction +0",53, as it appears that about
2j was not illuminated.
(£) Observed at or near the 4"' wire, with power of
50: cloudy: the nucleus so small as to make
the observation extremely accurate: the correction
-6",30 is applied for change of N.P.D. in 35",
and -0",23 for curvature of path. The correc-
tion for parallax is not applied: the factor for
hor. eq. parallax is 0,9382.

(a) Veiy good.
(4) The micrometer wires placed on the next divisions.
(c) Observed with power 50 : the second observation at leaving the
field: the correction - 18",87 is applied for change of N.P.D.
in 2™ .56', and - 6",97 for curvature of path : the factor for
paraUax is 0,9143.
(d) The S.L. near 4'^ wire, and the N.L. between 41I' and S"" :
both are corrected for change of N.P.D. in 20".
(e) The observations were taken at the 1" and 4* wires and at leav-
ing the field: the change of N.P.D. insensible: the power used
was 50, and the observations not very good : the factor for
paraUax is 0,8993. (/) The factor for parallax is 0,9131.
(ff) In this and the next few observations the differences of the
microscopes do not agree with the differences before this time :
but they seem to return afterwards to their several magnitudes.
(A) Without dark glass : neither limb good.

best kind.
t The circle in the same position as in series 51,
the clamp not being touched.
II The circle in the same position as in series 53.
§ The planet pretty well defined: occasional passing
clouds. Graham had stopped, and was set going about
56' behind Hardy: it stopped again after series 56: the
times in series 56 are by Graham, and those in the
other series by U. The star (;y) is much brighter than
(z), and the observations mucli more satisfactory.
U Very faint.

Apparent N.I\D. of small Stars, observed with Mars.
(The letter M. denotes that the Comparison is made with the Micrometer only. The R.A. are inferred
from the time of passing the middle wire, compared with the time of passage of the Index-error Star :
it is probable that the wrong wire has sometimes been noted, and that the 2R. is l6^ in error. The
wires mentioned conjecturally in the Notes to the Observations are adopted here.)

* From a defect in the apparatus for moderating
the illumination, the Comet could not be observed on
the wires till late in the evening. The nucleus well
defined with various powers.
t The observations difficult and unsatisfactory. No
nucleus visible till near the last series.
J The Star and the Comet appeared to coincide
exactly. The hour circle was not read.
II The Comet appeared as a blur, three or four
minutes in diameter.
§ The nucleus sharp and well defined, bearing il-
lumination well : appeared like a star of the 7th mag-
nitude, and the observations are as good as could be
made on a star.
Observed with the Equatokeal and the Clock Graham. 1835.

* The Comet near a Ursae Majoris, and about equally
bright. The light of the Comet filled 3-4ths of the
field, but its nucleus was not more than 40" in
diameter. The illuminating apparatus is improved.
t Before these observations, thicker wires had been
inserted in the wire-frame, in the same places (as
nearly as possible) as those used before. The wires

were not properly adjusted in position. Observations
made among clouds: sometimes a brilliant and sharp
nucleus visible, but generally the observations are not
good.
% The observations on the whole are very good :
the wires too thick. The sky clear.

* The observations generally good.
t From later observations of this star, there is
reason to think that the transit here ought to be in-
creased 1"".
X The nucleus bright: the Comet visible with the
telescope before any stars could be seen with the naked
eye. About as bright to the eye as ft Aquilas. The
pointer of the hour circle seems to have been disturbed,
and to read too much by 30'.
Observed with the Equatoreal and the Clock Graham. 1835.

• Observations made before dark, and interrupted
by clouds.
+ The two first observations made shortly after
sunset, and the Comet too faint. The other observ-
ations are pretty good. No illumination used. For
the observations of this day and Nov. 18, the refrac-
tion is computed with great accuracy.
X Observations not very good: the Comet very
faint, and the wind so loud as sometimes to drown
the beats of the clock completely.
Observed with the Equatoreal and the Clock Graham. 1835.

* The observations of Sept. 2 very doubtful, from
the extreme faintness of the Comet. Series 103 is the
best.
+ The Comet was observed on Sept. 20, by making
it pass through the great notch of the comb-plate, as
its faintness prevented the use of illumination for the
wires. The observations good.
i The Comet observed as on Sept. 20.
II On Sept. 27 the Comet was bisected with the
fixed wire. The observation of the star G very un-
satisfactory : the instrumental absolute determination of
the Comet's place is probably as good as the differential
determination.
Observed with the Equatoreal. 1835.

* No star could be found within a considerable
distance of the Comet.
t The observations difficult, but not very bad. The
micrometer for P in series 145, was not read till the
morning following the observations : there is not, how-
ever, any reason to think that it had been disturbed.
It seems probable that in series 143 the micrometer
was read wrong by two revolutions, or 1'.7" nearly.
X On Oct. 5 the Comet was observed by making
it pass through the deep notch of the comb.
II Comet extremely faint, and observations made
with great difficulty.
Observed with the Equatoreal. 1835.

* The nucleus ill definedj and the observations
therefore unsatisfactory.
t Clouded immediately after the first observation :
all the others pretty good.
J It appears that there is some error in this ob-
servation.
II Comet ill defined: observations taken with diffi-
culty. It seems that the pointer is shifted so as to
increase the readings by 5'.
§ Every circumstance favourable: the observations
beautiful.
Observed with the Equatoreal. 1835.

* A new set of wires inserted. The Comet had
nearly the same appearance as on Sept. 2, or was
even more faint. The observations made by throwing
in light enough to enable the observer to see the
comb; then excluding it and endeavouring to bring
the Comet to the parallel of the great notch.
t The micrometer placed on the next division,
t The Comet seen several times among clouds, but
no further observations could be made.
Observed with the Equatoreal. 1835 and 1836.

The Greenwich Mean Solar Time and the Interpolated Right Ascension may be supposed
the same as those for the observations with the Transit in page 136.
The following Physical Observations on the Comet were made
at different times of its appearance.
Sept. 25. 9" . 45". to IS*". During the whole time the Comet (seen with the
Equatoreal, 3 f -inch aperture,) appeared to continue changing its figure: it passed
over three stars (the nucleus covering one), which were distinctly visible during
the whole time. About 11'' I thought that I could discern its nucleus. The
state of the atmosphere afterwards became so bad that it looked like a faint
misty patch. The power generally used was 46. (G.)
Sept. 27. The stars in the measure of polar distance (Series 130 and 131)
are about 8,9 magnitude. I saw the Comet when I could not see the stars;
therefore the Comet must be about as bright as stars of the 7th magnitude.
Clouds were collecting about the place when I began to observe, and kept
closing about it, so that I merely had time to get its place, without observing
whether it had a nucleus or not, or whether it kept changing its figure as
before. (G).
Sept. 30. 10\ The Comet is very much increased in brightness: the nucleus
appears nearly in the center of the nebulous matter: its general appearance
is smaller : in the course of the evening I saw it very plainly with the naked
eye, nearly as bright as 9 Geminorum. {G.)
Oct. 2. 9''. Clouds thinner about the place of the Comet than in other
parts of the sky : the Comet had the appearance of a pretty good star of 7,8
magnitude when clear: it continued in this state till 12\ merely visible by
glimpses ; about 12*" the sky became very clear : the Comet now had the appear-
ance of a star with a planetary disk surrounded with a dense halo: the Moon's
light made it appear small, altogether not 1' in diameter, and to the naked
eye a little brighter than 6 Geminorum. {G.)
Oct. 5. 12''. Sky very clear, and deep blue: the Moon shining brightly.
I scarcely think the Comet has decreased in size: occasionally I saw a large
Physical Observations on the Comet. 217
quantity of nebulous matter. I examined it with the powers 30, 46, 70, 100,
120, 180: its nucleus was well defined in all: it bore the power 180 very
well: about 13". 30"". I saw it with the naked eye, but I could not see
9 Geminorum. (G.)
Oct. 7- 11''. Comet excessively faint, and no nucleus: at first appearing
as a little mist, which would not have attracted any notice had we been
ignorant of its being a Comet : it afterwards became brighter, but till after
13"' no nucleus was visible: from 12^ to IS"" it appeared like a large bad blur,
or as stars appear by reflexion under bad circumstances. {G.)
Oct. 8. S*". The Moon is shining very brightly, and the Comet is visible
to the naked eye. On examining it, the nucleus was sharp and well defined,
enabling me to illuminate the field, when it appeared as a star of the 7th
magnitude. During the time that I was observing, it did not appear to
change, but kept a more uniform appearance than I have seen before. (G.)
Oct. 9- 7*". The Comet as bright as /3 Ursae Majoris, or rather brighter,
but not so sharp or with such shining light as that of a star, appearing larger
than a star. {G.)
Oct. 10. 7^- The Comet is as bright as a Ursae Majoris, to which it is
near. With the Equatoreal telescope the light of the Comet filled f or more
of the field : the nucleus but 30" or 40" in diameter (estimated by the teeth
of the comb). On the Moon rising, this lessened very much. At 11" nearly
the Comet appeared through the Northumberland telescope (20 feet focal length,
11 f inches aperture) with a nucleus, in the center of which was a sharp bright
point (which none of the other telescopes would shew) : the nucleus was extended
up and down, or had a tendency to an elliptic form : no appearance of a tail,
the only visible inequality of light seeming to be in the opposite direction. In
DoUond (3f inches aperture) and the Equatoreal, the nucleus was circular: no
point in it. (G.)
Oct. 10. 7". &c. The Comet near a Ursae Majoris. When the eye was
assisted by a lens which made the star appear like a point of light, the star
appeared the brighter: but when both were viewed by tht unassisted eye of

a very short-sighted person, so as to give to the star a diiFused Cometary ap-
pearance, the light of the Comet clearly preponderated. At about 11" directed
the Northumberland telescope to the Comet : with a low power (supposed to be
80) the nucleus appeared sharp, but in the judgment of all the observers
(^, G, and two others) it was apparently elongated upwards to the right, and
ill-defined there : in fact, as if it had a rudiment of a tail really turned
toward the Sun. With a higher power (about 200) the nucleus had no
boundary at all : it was quite impossible to say where were its limits. {A.)
Oct. 11. 9''. To the naked eye the Comet appeared to have a tail, but
in the telescope nothing of this kind could be made out : its nucleus and its
general appearance are the same. (G.)
Oct. 14. 6''. The Comet once seen well with the naked eye: it had a
tail in the right direction. {G.)
Oct. 17. 6''. Sky clear and cloudy. At times a nucleus sharp and very
brilliant : I thought I saw a tail, but could not be confident. {G.)
Oct. 18. 7'' &c. Sky quite clear as the evening advanced: the Comet had
a tail of 3° to 5", or perhaps more, in length, directed from the Sun : its
nucleus pretty well defined, but by no means so well as I have seen it:
much light above the nucleus, and much below it, as it appeared in the
telescope. (G.)
Oct. 18. 9''. Observed the Comet with the Northumberland telescope, and
the same low power (80) as before. The nucleus bright, but no distinct sharp
boundary. In the opinion of all the observers {A, G, Mr Whewell, and four
others) the strongest light was defined by a line nearly vertical, the line pro-
ceeding upwards from the right-hand side of the nucleus, and the light to the
right being fainter. A thought that there was a sort of horn projecting up-
wards (its right-hand boundary being the line above mentioned) : Mr Whewell
thought that the light was bounded by an obtuse angle, one side being the
above-mentioned line, and the other a line sloping downwards to the left. The
above appearances are as seen in the inverting telescope. The Comet was
about as bright as a Aquila;. {A.)
Physical Observations on the Comet. 219
Oct. 19- 6''. With Equatoreal. The Comet nearly as last night. It was
impossible to determine the limits of the nucleus, which appeared only as a
condensation of light gradually shading off. Sometimes it appeared merely as
a blur. Its tail not so long as last night. The nucleus appeared at times
better defined on the apparent right than on the left. (G.)
Oct. 22. 6'\ The nucleus bright- The Comet seen with the Equatoreal
long before dark, and before any stars were visible: it was tolerably well defined
on the apparent right, but on the left it shaded off so gradually into the
nebulous matter, that I could not define its limits. It appears to consist of
three different degrees of density : 1st. The nebulous light, whose limits cannot
be made out : 2d. The nucleus : 3d. A very bright spot near the apparent
lower edge of the nucleus, appearing at times brilliant and sparkling. To the
naked eye the Comet is about as bright as /3 Aquilse, with a tail about 1° or
li" in length. (G.)
Oct. 23. 6^- The Comet blurred, no distinct nucleus : the sky not clear
more than half an hour. (G.)
Oct. 24. 6''. The Comet better defined on the right than on the left, ap-
pearing much as usual : the tail about 2° long. The tail seemed to be supplied
with light from the nucleus : several issuings of light from the nucleus were
seen, having much the appearance of small streamers in an Aurora Borealis.
No appearance of a second tail. {G.)
Oct. 26. 6^. Many clouds : when clear no tail of the Comet could be
seen. {G.)
Oct. 27- 6''. The Comet very clear: the nucleus sharp and pretty equally
defined on the right and on the left side: it was more nearly in the center
of the nebulous matter than it has been lately. The Moon's light nearly ob-
scured the tail : about 2° of length visible with the naked eye. In successive
trials with the Equatoreal, the tail (as seen in the telescope) appeared to occupy
3"", 5™, and 6" of right ascension. (G.)
Oct. 29. B*". The nucleus best defined at the upper right-hand side : no
sharp boundary at any other part. The nucleus elongated up and down ; the

at the right-hand extremity of the axis minor was a very sharp and well-
defined spot, often brilliant and sparkling. The Moon was shining brightly,
and very little light visible about the Comet : no tail visible either to the
naked eye or with the telescope. {G.)
Nov. 1. 6^. Sometimes clear and sometimes cloudy. The Comet appeared
about as bright as stars of the 3d magnitude : very little nebulosity : no tail.
It appears probable that we shall not again see a tail, therefore I may remark,
that I have never observed any curvature in it : it has always been directed
from the Sun, and has gone round with the Sun : I have never seen a second
tail in any direction : nor any thing to suggest the notion that it revolves on
an axis : but from the attention with which I have watched it, I think, if such
things had been, I should have seen them. {G.)
Nov. 8. 5\ Sky clear: the Comet about as bright as stars of the 5th
magnitude : when the Comet was visible with the telescope, 47 Ophiuchi could
not be seen with the telescope : v Serpentis was a little brighter than the Comet.
It appears that the part of the Comet now seen, is the spot mentioned as im-
bedded in the nucleus on Oct. 29, &c. There was a little luminosity round it :
sufficient to give warning of its approach to the field 7* or 8' before it entered.
(G.)
Nov. 12. 5^. Comet seen for a few minutes only: probably as bright as
stars of 6 mag. or 6,7 mag. under the same circumstances. (G.)
Nov. 15. S*". I judged the Comet to have as much light as stars of the
5th magnitude, but it was a diffuse misty light: the impression on the eye
was about equal to that of a star of the 6th magnitude. No stars could be
seen iii its neighbourhood, except tj Ophiuchi and v Serpentis. I examined the
sky for a considerable distance round the Comet's place: and therefore if there
are stars, the Comet must be brighter than they are. A rudiment of a tail
seen in the right direction. Twice during the observation, for a moment, a
point of the Comet was as bright and with light as sharp as stars of the 2d
magnitude when well defined and clear. {G.)
Physical Observations on the Comet. 221
Nov. 18. 5". The Comet about as bright as stars of the 9th magnitude
under favourable circumstances. (G.)
Dec. 10. 19". The sky very clear about the Comet's place, but the Comet
could not be seen. (G.)
1836. Jan. 15. 18*". A nebula observed instead of the Comet: no other
object visible. {G.)
Jan. 16. 18". The same nebula seen. The Comet had nearly the same
appearance as on Sept. 2, or if there was any difference it was fainter and
not so large, appearing as a very faint mist. J. G. said that it appeared occa-
sionally to him like a very faint star, which then spread itself into a mist. (G.)
[The last-mentioned phenomenon is undoubtedly an ocular illusion, arising from
the over-exertion of the eye. (^.)]
Jan. 27- IT*". The Comet seen several times between clouds : its appear-
ance is much altered : it appears elliptical, the axes of the ellipse being about
1' and f of 1': the longer line being parallel to the horizon, or the preceding
part perhaps a little higher in the field. (G.)

METEOROLOGICAL OBSERVATIONS.
The following Observations were made in conformity with the rule laid down by
Sir J. Herschel in a notice circulated by him from the Cape of Good Hope. The
observations could not be commenced on June 21, 18", as the notice was only received
on June 21, about 21". The observations of Dec. 21. were inadvertently omitted in the
general confusion which my departure occasioned in the Observatory. The error of a
chronometer had been previously computed, and by means of this the observations were
made pretty accurately at the time indicated: as the error of time in no case amounted
to one minute, it has not been thought necessary to mention the exact time. The direction
of the wind was judged by personal sensations, as there is no vane on the Observatory.
From 16" to 20" inclusive, the observations were made by me : the rest are by Mr Glaisher.
