GENERAL CATALOGUE OF STARS
FOR
1885'0,
INTRODUCTION.
The results given in the following Catalogue are based upon observations made
with the Cape Transit-Circle from 187!) June 1, to 1885 February 8. They
represent the Mean Right Ascensions and Declinations of the Stars at the Mean Epoch
of observation, reduced without Proper Motion to the Equinox 1885'0.
The necessity which had arisen for repolishing the object-glass of the Transit-
Circle, and of replacing the easily worn gun-metal screws of the micrometer-
microscopes by steel screws, compelled the interruption of meridian observations
in February 1885. As the programme for the observation of the Fundamental Stars
of Schonfeld's Durchmusterung was completed, it seemed desirable to prepare the
Catalogue for the use of Astronomers, particularly as the whole work would then
depend upon observations with the instrument in an unaltered condition.
The MSS. of the Catalogue has been for some time ready, and was only withheld
from press in the hope that the question of change of Astronomical Latitude would
be sufficiently settled to permit the application of definitive corrections for the
elimination of its effect, and that the Leiden observations would be ready for
discussion of the Refraction. These matters, however, seemed to ripen slowly, so that
it was at last decided to publish the Catalogue in its original form rather than impair
its usefulness by farther delay.
The working list for this Catalogue was formed originally of the following classes
of Stars :
Fundamental Stars for the meridian observation of the Stars of Schonfeld's
Durchmusterung.
VI
Stars suitable for determining the errors of the Refraction Tables by observations
at Greenwich, Leiden, and the Cape.
Southern Circumpolar Stars.
Stars employed in connection with Heliometer observations for scale-value and
Stellar Parallax.
Special observations of a and /3 Centauri.
To this list there were subsequently added :
Stars employed in the Longitude operations connecting Aden and the Cape.
Stars employed in the Latitude and Longitude operations connected with the
Geodetic Survey of South Africa.
Comparison Stars employed in the observations of Comets and Minor Planets.
Stars whose occultations by the Moon had been observed.
In 1884 a new working list was prepared containing, in addition to Stars of the
above-mentioned classes, all Stars of the 4th Magnitude or brighter which could be
observed at the Cape, and any Stars additional to these that were to be found, or of
which more accurate places were required for future use, in any of the National
Ephemerides. Observations of Stars of the latter classes are necessarily very
incomplete in consequence of the interruption of the work in February 1885.
Complete series of observations of all these Stars wilr be found in the next Cape
General Catalogue, in which it is proposed to include the results of the Cape meridian
observations from March 1885 to 1895.

the Star is one of the Fundamental Stars for the zones of Schonfeld's Durch-
mustencny (Ast. Nach. 2890-91) ; a dagger (f), that the Star is one of the
Fundamental Stars for subsequent meridian observation of the zones of the
Cape Durchmusterung, between 20 and 80 of South Declination. (Auwers
Monthly Notices R.A.S., Vol. XLVIL, pp. 455-473.) When the Star belongs
to both these lists the asterisk only is affixed, and the note " Fundamental
Star for Southern Zones " is printed at the bottom of the page,

" Bradley or Lacaille." This column gives the corresponding number in Auwers'
" Neue Reduction tier Bradleyschen Beobachtungen," or that in the British
Association Catalogue of Lacaille's observations ''''Catalogue of 9766 Stars
in the Southern Hemisphere."
When the Star is in one of these Catalogues only, the numeration alone
is sufficiently distinctive, when it is in both Catalogues the Bradley Number
is given with an asterisk attached.
" Piazzi." This column gives the Hour and Number in Piazzi's Catalogue (Edition of
1814).
" B.A.C." The number in the British Association Catalogue of 8377 Stars.
" Star's Name." For Stars contained in Auwers' Bradley the nomenclature of that
work has been retained, only substituting Argus or Puppis for Navis. For
Stars not in Auwers' Bradley the nomenclature of the Fundamental list
(Ast. Nach. 2890) was adopted. For all other Stars between the South
Pole and Declination 23 the nomenclature of the Argentine General
Catalogue was employed, and for Stars North of Declination 23 that of
the British Association Catalogue. The only exceptions to these rules are
a very few close Circumpolar Stars which are designated by letters long in
use at the Cape.
For otherwise unnamed Stars the Catalogue number is referred to in the
following order of preference :
(1.) Auwers' Bradley, referred to as Bradley.

RIGHT ASCENSIONS.
The Clock- Stars employed are those of the Fundamental Catalog fur die Zonen
Beobachtungen am Nordlichen Himmel, which are situated between the limits of + 10
and 10 of Declination.
The Right Ascensions of Clock- Stars are not included as determinations unless at
least five observations of Clock- Stars have been obtained on the same night.
The Right Ascensions of Stars within 10 of the Pole have not been included
as determinations unless either the Star has been observed both at upper and lower
culminations, or the Azimuth has been otherwise strongly determined on the same
night, that is to say, by double transits of other circumpolars, or by transits of
at least four Circumpolar Stars whose places have been recently determined
fundamentally. The observations have been entirely made by the method of " Eye
and Ear."
Personal Equation.
The ordinary corrections for Personal Equation applicable to the determinations
of Clock-Error need not be here given in detail ; the results as determined from time
to time will be found in the Introduction to the Cape Meridian Observations 1879-81,
p. xxvi., and 1882-85, p. xxv. The Clock-Rates from day to day are corrected for
Personal Equation, but the Clock-Error as determined by the observer at the mean
epoch of each set of observations has invariably been employed in the reduction of all
observations of that set. The Right Ascensions are, therefore, practically unaffected
by Personal Equation, unless that equation varies for Stars different in Magnitude
and Declination from the Clock- Stars.
In order to determine the variation of Personal Equation for Stars of different
Declinations, a long series of observations was made in 1879. A list of Stars was
prepared, divided into zones of Declination ; two observers were on duty at the same
time, and each observed the transit of the same Star over several wires, changing
places at the eyepiece at the middle of the transit. Thus one observer, G, would
observe the first three wires, the other, F, the last three wires for the first Star, and
vice versa for the second. Then putting
Clock slow (true) = Clock slow (as observed by G-) + G-
= (as observed by F) + F
with similar notation for the other observers, and adopting
G + F + M + P + I = O s -000
a number of equations was obtained, from which the following values of G, F, M, &c.
were found.

The sudden variation in these results at the Zenith at once led to the suspicion
that there must be a considerable personality dependent on the apparent direction
of motion of the Star across the field of view. To test this point a list of Stars
culminating near the Zenith was selected. The observer, facing North, noted the
times of transit over the first three wires, and then, facing South, noted the times of
transit of the same Star over the last three wires, and vice versd for the next Star.
The results for the various observers were
G N -
G s = -
h 8 '076.
F N -
F a = -
F -079.
M N -
M s = -
r- -122.
IN ~
PS =
h -015.
IN -
Is = -
h -066.
Thus all the observers have a systematic error, similar in character, depending on
the apparent direction of motion across the field of view. It is perhaps worthy of
remark that the observer P, whose systematic error in this respect is smallest, and
almost insensible, is ambidextrous, as he handles tools, &c. with equal facility with
either hand. In consequence of this result I had a reversing prism mounted between
the eyepiece and the observer's eye.*
* The adjustment of the reversing prism ia a delicate operation requiring the greatest care and
nicety. The prism may not be made too large, otherwise the observer's eye is too far removed
from the eye-lens and the field of view becomes too limited. On the other hand, when the prism
is of the proper size, unless its neutral axis is rigorously parallel to and coincident with the optical
axis of the eyepiece, a part of the emergent pencil is cut off, and a non-symmetrical image of the
Star is the result. The only satisfactory test is to examine the emergent pencil with a lens or
dynamometer (in the manner usually employed to measure the magnifying power of a telescope)
and so ascertain whether the full image of the object-glass can be seen in full illumination in all
positions of the prism's rotation.
A 11907. b 2
Xll
This prism is capable of rotation about its axis, and consequently of reversing the
apparent direction of the Star's motion across the field of view. To prevent any
confusion on part of the observer in the use of the prism, the following simple device
was employed to define its position. The prism itself is mounted on a brass disc,
Fig. 1.
Fig. 2.
Fig. 3.
Fig. 4.
Fig. 5.
Fig. 6.
shewn in plan and section in the accompanying Figures 1 and 2. This disc can be
rotated by the observer with the greatest ease, without disturbing the focal adjustment
of the eyepiece ; the prism, as shewn in Figure 2, is mounted on this disc.
xirt
A portion of this disc is filed away to form a flat a b, Figs. 2, 3, 4, 5, 6. The
line a b is at right angles to the plane of the base of the reversing prism, therefore
when this line is placed vertically, as in Figures 3 and 4, the apparent motion in
Eight Ascension is not changed, but when the line a b is placed horizontally, as in
Figs. 5 and 6, the apparent direction of motion is reversed. These positions of the
prism are denoted in the observer's book by the letters V and H respectively. .
After November 1880 in every transit-observation the first three wires were
observed with the prism in position H, and then a like number with the prism in
position V, or vice versa ; thus, when the separate wires are reduced to the middle
wire, the mean result is free from personal error depending on the direction of motion.
Almost all the Stars observed before the adoption of the reversing prism were
within 30 of the Equator, hence practically the same correction would have to
be applied to the Clock- Stars as to the Stars observed for place, therefore no correction
for the V H discordance has been applied to the results 1879 to November 1880.
In all observations subsequent to the latter date the error depending on the direction
of apparent motion has been systematically eliminated by use of the reversing prism
as above described. After the reversing prism had been some time in use, the
following results were obtained from a discussion of the observations, by reducing
the observed times in the positions V and H to the middle wire.

Now position V gives for Equatorial Stars the same apparent direction of motion
with reference to the observer's right or left hand that position H does for Stars South
of the Zenith ; thus the above results for F, M, P and I agree in sign, and (with
the exception of M) in amount, with those derived from the observation of transits
of Zenith Stars in reversed positions of the observer with reference to North and
South. The agreement of the values of V H (except in the case of observer I)
for Polar Stars reduced to the great circle, is very close. For slow moving Stars
the observer I had always a considerable and rather variable Personal Equation
(Cape Observations 1871-75, p. ix.), and his observations seldom enter into the
determinations of the Right Ascensions of Circumpolar Stars.
XIV
It seems probable therefore, that, with the systematic use of the reversing prism,
the effect of Personal Equation depending upon Declination is to a great extent
eliminated.
In connection with the discussion of the Meridian Observations of the Mars
Comparison Stars in 1877 it appeared that observations by " Eye and Ear " were not,
in the mean, affected by magnitude (Memoirs, R.A.S., Vol. XLVL, p. 80). On this
account no special steps were taken to determine the Personal Equation depending
upon magnitude till the Meridian Observations of the Victoria and Sappho Comparison
Stars were under discussion by Professor Auwers, when, at his request, special
observations were made for the purpose.
The Right Ascensions of the Victoria and Sappho Stars were observed by the
" Chronographic " method ; the results were communicated to Professor Auwers, and
will be published in his discussion of the Meridian Observations of these Stars. At
the same time (1890 March to June) observations were made to determine the
personality depending on magnitude for "Eye and Ear" Observations, and, contrary
to expectation, the correction was found to be very marked.*
The work of preparing the Catalogue was then too far advanced to permit the
corrections to be applied without undue labour to the individual results, but the
corrections applicable to the different observers are so similar that the following means
may be adopted as applicable to all the Catalogue places.

observations to make them produce the same Clock-Error as the Direct observations.
M = + 8 -054 ; P = + 6 -008 ; C = + O s -<345.
No correction, however, has been applied in the Journals to the observations of Right
Ascension made by Reflexion, so that such observations are reduced on their own merits,
and with a Clock-Error derived solely from the Direct observations,

DECLINATIONS.
The reader is referred to the Introduction of the Cape Meridian Observations
1879-81 (pp. xiii-xxiv) for an account of the methods by which the errors of
graduation of the Circle were determined for each single degree of the Circle. These
corrections have been rigorously applied to the results given in the Annual Catalogues.
In the Introduction to the Cape Meridian Observations 1882-85 will be found an
investigation of the errors of the screws of the Circle-Microscopes, and of the effects of
their progressive wear since 1879. These results, as applicable to the Runs at various
epochs, are given in Table M 1? p. xviii., and, as applicable to the Circle-Microscope
readings, in Table M 2 , pp. xviii-xxi ; the corrections depending on the reading of the
eyepiece micrometer-screw are given in Table N, p. xxi loc. cii. The published results
of Cape Meridian Observations 1882-85 are corrected for these errors of the screws,
but those of 1879-81 are not so corrected, because the fact of rapid wear of the screws
XVI
had not been established when these observations were printed. The necessary
corrections for the Screw-errors previous to 1882 have however been since computed
and applied to the separate observations by the methods described, p. xvii. loc. cit. t
so that the positions of Stars given in the present Catalogue are free from the errors
in question.
The results for N.P.D. given in the annual Catalogues are formed on the
assumptions,
1. That the results are unaffected by instrumental Flexure.
2. That the Refractions of Bessel's Tabulae Regiomontance are rigorously
applicable.
3. That the Latitude is -- 33 56' 3"-20.
Flexure.
By observations of opposite horizontal Collimators, the half sum of the Horizontal
Flexures to North and South was determined seven times in January 1881 and eleven
times in February 1885, with the result that the upper semi-circle is measured
= 180 0' 0"-924, or that the correction for Mean Horizontal Flexure is = - 0"'462 ;
Probable Error 0"'020.
The separate results are given in the Introduction to the Cape Meridian
Observations 1882-85, p. xxviii. The negative sign indicates that the Instrumental
Zenith Distances require a negative correction, in other words the eye-end of the
telescope bends or falls more than the object-glass end.*
In preparing the Declinations of the present Catalogue the Flexure is assumed
to be
OM6 sin Z.D.
In 1 884 a large number of observations was made by reflexion. The results are
given in the Introduction to the Cape Meridian Observations 1882-85, p. xxx. In
the preparation of this Table the correction for the Latitude of the mercurial trough was
erroneously applied to the values of R D from the formula
0"'08 sin Z.D.
The proper correction is 0"'16 sin Z.D.
* The reader is requested to correct a mistake on p. xxix of the Introduction to the Cape
Meridian Observations 1882-85, where the erroneous conclusion is drawn that the excess of the
Instrumental Z.D. is due to greater bending of the object-glass end than of the eye end.

The figures in column 9 of Table I. are obtained on the assumption that the true
Flexure correction is
- 0"'46 sin
The resulting values of R D resemble the corresponding values for the Greenwich
Observations.
It is therefore important to decide whether the Reflex observations should be
reduced to the Direct observations (after the latter have been corrected for Flexure),
or whether both sets of observations should be reduced to the mean system - .
At Greenwich it has always been the practice first to apply the correction for
Flexure on the assumption that the true value of the Flexure-Constant is derived from
the observations of the Horizontal Collirnators, and that the Flexure varies as the sine
A 11907. CAPE OBSERVATIONS. '
xvm
of the Zenith Distance. This done, the values of R D are obtained, and an expression
is found to represent these values of the form
a + b sin
or, a + b sin cos 2
and corresponding corrections are applied to reduce both the R and D observations to
R + D
the system - .
m
This system of reduction obviously implies that the corrections first applied
represent the true Instrumental Flexure, and that the R D discordance has some
other origin than true Instrumental Flexure.
The practice is based on a Memoir by Sir George Airy (Memoirs R.A.S.,
Vol. XXXII., pp. 9-17), in which its distinguished author comes to the conclusions
1. That "the origin of the discordance expressed by R D lies in some con-
" formation of the warmer and cooler strata of the atmosphere in the
" immediate neighbourhood of the circle."
2. That " the means of the R and D results are more reliable as absolute
" measurements of Zenith Distance than those of R or D only," and
that " no Colatitude of an observatory where direct observations alone
" are used is certain to a quarter of a second."
With the first of these conclusions one can readily concur. The second, however,
is hardly tenable in face of the first ; for it implies that the law of Refraction will be
better represented by the mean direction of two rays, one of which has traversed a
much longer space of air (admitted to be irregularly heated by radiation from the walls
and pier of the instrument) than by the direction of a single ray entering the object-
glass between the vertical shutters, where there is, or should be, a free draught of
outside air.*
The proof given by Sir George Airy in favour of his view is that, in the mean of the
R and D observations, the observed Latitude of the Greenwich Circle is found to be
the same, within narrow limits, during the three epochs 1836-41, 1842-48, and 1851-60;
whereas, if the Latitude is deduced from the D observations only, the resulting Latitudes
of the first and last of these periods differ from that of the middle period by 0* - 26
and + 0"'28 respectively.
' In the Greenwich and Cape Instruments the observer and the mercury trough occupy a pit or
well, and the latter, except for observations at considerable Zenith Distance, is below the level of
the floor.
XIX
But it is not difficult to find other reasons for these discrepancies. In those days
there were no investigations of the errors of the Screws of the Micrometer-Microscopes,
which, as has already been shewn at Greenwich, might alone readily account for the
discordances in question ; nor in the case of the Mural Circles employed in the first
two periods was there any effective determination of the division-errors. For these
two periods also the Zenith- Point was determined from observations of Stars D and K,
and all these determinations were assumed to be common to all Stars, and in computing
the D results the instrument was assumed to be free from Flexure for, indeed, there
were no independent means of determining it by Collimators. For the last group of
observations, 1851-60, the Transit-Circle was employed, the Zenith-Point was
determined by Nadir Observations, combined with D and R observations of Stars, and
in forming the D results the Flexure determined by the Horizontal Collimators was
applied ; but this determination (upon which the calcukted amount of the R ])
correction entirely depends) is apparently based upon the results of only five Flexure
determinations, which range in value from + 0"'20 to + 0"'88.
The observations in the mean of the two positions R and D do eliminate not only
the term of the Instrumental Flexure depending upon sin , but also errors of the
Nadir-Point, and diminish to some extent the effects of errors of division and errors of the
Micrometer- Screws. But if the R D discordance has the physical explanation which
Sir George Airy has given to it, then it is quite clear that the R results (however
much they may have the effect of smoothing mean values of the Latitude) are in
reality erroneous, unless they are reduced with a different law of Refraction, applicable
to the mean or special condition of temperature of the irregularly heated air within
the Observatory itself.
Mr. Christie, in his paper " On the systematic errors of the Greenwich North Polar
Distances'" (Memoirs H.A.S., Vol. XLV.) apparently takes the opposite view, for at
page 154 he argues as follows :
" The change in the R D and Flexure corrections on the piercing of the cube:
" (subsequently to the date of the Astronomer Royal's paper) was not accompanied
" by any change in the shutter openings, or in the general meteorological conditions
" of the room. There was, on the other hand, a change in the mechanical state v of the
' instrument, and in the method of making the Flexure determination. For the latter
il the observation of one Collimator by the other was made after 1866 through the
" pierced cube instead of with the Transit-Circle raised."
These words imply that the origin of the R D discordance is, in Mr. Christie's
opinion, due to instrumental causes, because, with the instrumental changes, and
without any change in the shutter openings, the signs of the Flexure and of the R D
discordance were changed.
A 11907. e 2

As a matter of fact, however, this change of sign is only apparent, not real.
If, for sake of simplicity, we take the epochs during which the corrections for
R D were assumed of the form
x + y sin
we have the following :

in the constant of the correction in the
result may appear to be due to the piercing of the cube, but having regard to the
fact that the flanges of the tubes are bolted near to the margins of the cube, the
mechanical conditions are against such a theory. The wider range of Reflex obser-
vations, after the new Collimators were mounted, combined with the employment of
a formula not truly representing the physical facts**, is apparently the cause of the
small apparent increase. Be that as it may, the unquestionable fact remains, that the
true Flexure of the Greenwich Transit-Circle follows practically the same law from,
first to last.
Professor Simon Newcomb calls attention to this fact in his paper on the North
Polar Distances of the Greenwich Transit-Circle (Astronomical Papers of the American
Ephemeris, Yol. II., pp. 414418), and asks the pertinent question, " How is it possible
" that a change in the Astronomical Flexure should have occurred without any change
" in the Zenith Distances measured with the instrument ? "
* Taken for 1851-61 from Mr. Christie's paper, p. 156, loc. cit., where, however, the values
have to be doubled and corrected for inclination of the vertical at the surface of the mercury the
results are then as here given.
** The true law of E D discordance, apart from Flexure, does certainly not follow the law
of sin { ; the proof is a reductio ad alisurdum, viz., that if Reflex observations could be continued
to the horizon, the calculated effect of R D would reach a maximum at the time when the
Reflex and Direct rays coincide.
XXI
The true explanation appears to be that suggested by Newcomb loc. aV., viz., that
since the Collimators were viewed through the triangular openings in the central cube,
the determinations of Flexure are erroneous.
This view is confirmed by the results given in Professor Turner's paper (Month/;/
Notices, Vol. LII. p. 146) " On observations for coincidence of the Collimntors
' throuqh the cube of the Transit- Circle at the Royal Observatory, Greenwich." This
investigation shews that considerable systematic errors are produced in the coincidence
of the Collimators u by viewing the South Collimator with the North one through
' ; 8 holes of sector form cut in the central cube of the Transit-Circle." Unfortunately
in Professor Turner's paper the investigation is restricted to the effect on Collimation,
and is not extended to the effect on Flexure, but the systematic error produced in
the coincidence of the Collimators is quite sufficient to form a possible vera causa for
the apparent change of Flexure.
It is much to be desired that a long series of observations should be made to
determine the Flexure of the Greenwich Transit-Circle both on the old plan and
on the new.
In the case of the Cape Observations I am convinced by many considerations, and
in part by the results of an unfinished investigation in which I have been for some
time occupied, that Airy's explanation of the R D discordance, originally suggested
by Faye, is the true one.
Although the vertical shutters of the Transit-Circle Room are always opened from
three o'clock in the afternoon, the thick outer walls of the Observatory heated as
they are by the strong sunshine at the Cape never acquire during the night the
temperature of the outer air. Thus for Reflex observations the rays from Stars enter
strata of air very irregularly heated. On the other hand the Direct observations are
made in the air-space between the open shutters, where (as the observations arc
always made with both the vertical and horizontal shutters fully opened) there is
a free draught of air, and the temperature is less different from that of the outer air,
than it is below the level of the axis of the Transit-Circle.
For these reasons, and having regard to the fact that the errors of the Micrometer-
Screws and of the Circle-divisions have been thoroughly investigated and the
corresponding corrections applied, I am fully convinced that the Direct observations
corrected for Flexure represent the true Zenith Distances far more accurately than
do the mean, of the Reflex and Direct observations.
In the Annual Catalogues the results are given without corrections for Flexure or
R D, and the Reflex results are not corrected for the position of the mercury-trough.
Taking the mean values of D R before the application of the correction 0"'16 sin ,
XX11
and sweeping a curve through the results, we obtain the following corrections to
reduce the Reflex N.P.D. 's of the Annual Catalogues to the system of those observed
Direct.

The range of 1'olar Distance is quite insufficient to allow an independent
discussion of the Refraction., and, therefore, we assume in the first place that thi"
adopted Tabular Refractions (those of Bessel's Tabulas Pet/iomontance) require no
correction. On this assumption, having regard to the weights, we obtain :
Correction to the assumed Colatitude = + 0"'lo.
The following Table III. gives the combined effect of the corrections for
Colatitude and Flexure :

In forming the N.P.D.'s for the General Catalogue the Reflex observations
of N.P.D. were first reduced to the system of Direct observations by the corresponding
corrections taken from Table II. The mean of the observations R and D so corrected
was then taken, having regard to the number of observations of each, and the result
was corrected for Flexure and Error of Colatitude by Table III. The N.P.D.'s thus
found were transformed into the Declinations which are printed in the present
Catalogue.
D
The Catalogue as it stands therefore represents the Declinations which would
result from the following conditions :
1. That the true Zenith Distances are obtained from the Direct observations
corrected for Flexure by the formula
- 0"-46 sin K.
2. That the Refractions of Bessel's Tabulae Regiomontancc represent the true
Astronomical Refractions at the Cape.
The resulting Latitude is -33 56' 3"'35.
It remains for discussion whether subsequent data obtained at the Cape and
comparison with the Greenwich observations shew that the Declinations of the
Catalogue require further systematic corrections.
Discussion of Flexure depending on cos .
The general law of Flexure may, from mechanical considerations, be expressed
with considerable certainty by
a sin + b cos .
Observations with the Horizontal Collimators give directly the values of 2a, but
there are no data to determine b unless it be assumed that the irregular Meteorological
conditions in the interior of the Observatory which give rise to the discordance R D
are symmetrical North and South of the Zenith, and the accuracy of the discussion in
this way is also vitiated by the uncertainty as to the law of the R D discordance.
In order to obtain an entirely independent value of b a number of pairs of Stars
were observed in 1887-90, both with the Transit -Circle and the Zenith-Telescope.
The Stars were selected in pairs like those employed for determining Latitudes by
A 11907. CAPE OBSERVATIONS. d
XXVI
Talcott's method, the components of each pair having a small difference of opposite
Zenith-Distance, and differing sufficiently in Right Ascension to be both capable of
observation with the Transit- Circle on the same night. Unfortunately, owing to the
pressure of other work, it was not possible to make the observations simultaneously
with both instruments ; but in every case only those Transit- Circle observations have
been used in which both components of the pair were observed on the same night.
To eliminate as far as possible the inaccuracy which might arise from difference
in the epochs at which the observations were made with the two instruments, the
corrections for Proper Motion have, where possible, been determined and applied, and
corrections have also been applied to the results for change of Latitude according
to Chandler's formula}.
The adopted value of a in the expression for the Flexure depends upon the
following results, which represent the means of the weekly determinations of Flexure
made with the Horizontal Collimators during the period over which the observations
extend :

There is ;i distinctly marked tendency to periodic change throughout the year,,
for we have
a
May to October (cold and wet) - 0"'340.
November to April. (warm and dry) 0"'26(>.
It seems probable that this small change is the result of a sagging of the
horizontal web, produced by the great increase of moisture in the winter months,
rather than of a change in the rigidity of the metallic parts of the instrument,
due to temperature.
The mean value of a is quit? constant within the limits of the probable error of
its determination, but differs markedly and persistently from the values of Horizontal
Flexure found for the period 1881-85.
In 1885, however, after the observations of the present Catalogue were finished,
a good many instrumental changes were made. The object-glass was sent home
and re-polished, new steel screws were made to replace the easily worn gun-metal
screws of the Circle -Microscopes, a new screw was also made for the eyepiece-
micrometer, and the latter was thoroughly overhauled and put in order. The finder
telescope was also removed (as it interfered with the symmetry of the instrument
and was practically never used), and the counterpoising of the instrument was
correspondingly re-adjusted.
These mechanical changes sufficiently account for the change of Flexure. For
these reasons the observations made previous to 1885 February 6 are reduced with the
Flexure Correction 0"'462 sin , those subsequent to that date with - 0"'303 sin .
The results of the comparisons of the Zenith-Distances as measured with the
Transit-Circle and with the Zenith-Telescope are given in the following Table.
The observations in question were all made before the Zenith-Telescope was
placed in Messrs. Repsold's hands for extensive alteration ; the results since
obtained are very much more accurate. But the faults of construction, which
were detected and have been remedied, were of a kind only to produce accidental
and not systematic errors.

It is obviously unnecessary to discuss these observations further, the factor of the
term of the Flexure depending on cos being nearly 2, the term b would be = O'^OS
if Chandler's terms for change of Latitude are neglected, or = 0"'00 if they are taken
into account. The Flexure is therefore quite symmetrical with respect to the Zenith.
It may be, however, of some interest to discuss the Cape Observations on
precisely the same plan as the Greenwich Observations, that is to say, to find an
expression of the form
x + y sin
representing the R D results, after the latter have been corrected for Flexure as
found by the Horizontal Collimators.
XXIX
The observations of R D from Z.D. to 20, however, are excluded, because
within that zone the full aperture of the telescope is not available.
We have, therefore, the following equations to determine x and y, the absolute
terms of the equations being taken from Table I., Column 9 :
Group. R-D. Weight. 0-C.
I. x - 0-84 y = 1-05 11-0 - 0-37
II. x - 0-79 y = 1-15 28-3 - 0'52
III. * - 0-74 y = - 0-59 30-9 O'OO
IV. x - 0-67 y = - 0-41 35'4 + O'll
V. x - 0-61 y = - 0-17 42-2 + 0'30
VI. x - 0-54 y = - 0-26 50'9 + 0'14
VII. x - 0-46 y = - 0-29 63-0 + 0'04
VIII. * - 0-39 y = - 0-35 45-6 - 0'09
XIV. x + 0-39 y = + 0-50 27'1 + 0'03
XV. y. + 0-47 y = + 0-69 15'5 + O'lo
XVI. x + 0-54 y = + 0-44 27'1 - 0'17
XVII. * + 0-60 y = + 0-34 19'2 - 0'32
XVIII. x + 0-69 y = + 0-76 37'2 + 0'02
XIX. x + 0-74 y = + 1-04 15'4 + 0'25
Having regard to the weights the Normal Equations are
447-53 x - 96-66 y = 44-52
96-66 x + 157-01 y = + 136-36
and
x = + 0-102 weight 388
y = + 0-931 136
The corresponding corrections applicable to the observed Zenith-Distances are
therefore
+ 0"-05 + 0"-47 sin 2.
From the evidence of the Zenith- Telescope observations, however, it appears
that the apparent dissymmetry of the measured Zenith Distances implied by the
term + 0"'05 is more probably due to the irregular distribution of the heated air in
the Observatory than to any instrumental error.
Discussion of the errors of the Refraction Tables.
For this discussion we have the following data :
A. Observations of N.P.D. of Circumpolar Stars at Greenwich (Ten- Year Catalogue

Introduction to the present Catalogue, pp. xxii-xxiv).
C. Observations of Stars mutually visible at Greenwich and the Cape. (Greenwich
Ten-Year Catalogue 1880, and Cape Catalogue 188.5.)
Let A u and \ denote the observed N.P.D. at either observatory for upper and
lower Culmination respectively,
A g and A the observed X.P.D. at Greenwich and the Cape respectively
(the latter being corrected by + 0"'lo for error of Colatitude),
R u and Rj the Tabular Refraction at either observatory for upper and
lower Culmination respectively,
R g and R c the Tabular Refraction at Greenwich and the Cape respectively.
Then assuming
Colatitude of Greenwich = 38 31' 21"-90 + X.
True Refraction at Greenwich = (Tabular Refraction) x (1 Y).
Colatitude of Cape = 123 56' 3"'3o + x.
True Refraction at Cape = (Tabular Refraction) x (1 y).
The three classes of observations afford equations of the following forms :
A 2X + (R u + R,) Y = A, - A u
B 2x - (R u + R,) y = A, - A u
C x - X + R,,y + R g Y = A, - A
GREENWICH N.P.D.
In discussing the observations it was intended to form the absolute terms of the-
'&
equations on two distinct plans.
R -f-' D
1. To assume that the N.P.D.'s should be reduced to the system ^ .
XXXI
2. To reject the Ileflex observations and reduce the results entirely on the assumption
that the true Nadir- Point is given by the Nadir observations alone, and that the Flexure
is represented by a sin + b cos , where a is determined by the Horizontal
Collimators.
The Greenwich Ten- Year Catalogue represents the former assumption except in so
far (as Professor Turner lias shewn, Monthly Notices, Vol. LIL, p. 374) that the
combined effect of Flexure and R D cannot be exactly represented in mean conditions
by a term depending only on sin . The results are however accepted as they stand.
The Greenwich Nadir-Point determinations are almost completely masked by
combining them with Nadir- Points derived from Reflex and Direct observations of Stars ;
but it appears, from a discussion made at Greenwich in 1877 (Introduction to Greenwich
Observations 1887, p. xlvii), "that the mean apparent correction to the Nadir
observation as found from Reflexion observations of Stars is only + 0"'01." This may
be accepted as a proof, in conjunction with the general result of Prof. Bakhuyzen's
discussion (Monthly Notices, Vol. LI., p. 288) that the term of the Flexure depending on
cos is insensible.
The only existing determinations of the term a of the Flexure of the Greenwich
Transit- Circle, previous to the perforation of the cube, are the following :

In addition to the proofs already quoted that the subsequent apparent change of
sign of the Flexure has been produced solely by viewing one Collimator by the other
through the 8 holes of sector-form cut through the tube of the Transit-Circle, Professor
Bakhuyzen's paper on "Variations of Latitude deduced from the observations of Polaris
made at Greenwich 1852-89 " (Monthly Notices, Vol. LI., p. 286 etseq.*) may be regarded
as conclusive, for he shows beyond doubt, loc. cit. " that the piercing of the cube in 1865
had no appreciable influence on the results."
XXX11
For the period covered by the Ten- Year Catalogue, and apart from small constant
quantities applied in different years, which in the mean are nearly zero, the corrections
depending on sin , in the name of R D, were (1880 Catalogue, p. 12)
+ 1"'225 sin .
This corresponds in effect to a Flexure correction expressed by
+ 0"'613 sin
which agrees almost exactly with the mean of the only known reliable Flexure deter-
minations, viz., those of 1850-64, quoted on p. xxxi, which give
+ 0*-62 sin ?.
Thus, whether the Greenwich observations are reduced to the system ^
(neglecting the departure of the true E, D curve from the law of sin ), or whether
they are reduced by the best independently known value of the Flexure, the results
are practically the same.
The Greenwich N.P.D. observations are therefore taken as they stand from the
Greenwich Ten-Year Catalogue.

In Tables B and C the figures in Column I. represent for the Cape the unchanged
N.P.D.'s of the present Catalogue. The figures in Column II. are' formed on the
ff i T\
assumption that the Cape N.P.D.'s should be reduced to the system - , that ; s to
say, the further correction
+ 0"'05 + 0"-47 sin
has been applied to the Cape N.P.D. 's of the present Catalogue.

Before forming the definite equations, however, it seemed desirable to examine
the question of the Tabular Refraction.
.
The Refraction Tables employed at Greenwich are those of Bessel's Tabulae
Regiomontance^ which are based on the Refractions of his Fundamenta. The theory of
the latter is essentially that of Laplace, but the constant of Refraction employed by
Laplace was increased by Bessel in the Tabulae Regiomontanoe in the ratio of
1 : 1*003282, in accordance with the result of his discussion of Bradley 's observations.
Below 85 Z.D. the Refractions of the Fundamenta (increased as above) were found
to be too great, and were empirically reduced in the Tabulae Regiomontance to make
them correspond with the results of observations of Stars at low altitudes made by
Argelander at Abo. .
The theory of Refraction has been more completely developed on various hypotheses
since the days of Bessel. Radau in his " Recherches sur la theorie des Refractions
" Astronomiques " (Annales de T Observatoire de Paris, Memoires Tome XVI.) shews
(p. B 64) that the best modern Tables, though based on very different theories, are in
close accord for Zenith- Distances less than 80. Radau also shews (loc. cit.} that,
within the same limit of Zenith-Distances, the Refractions according to his own theory
are practically independent of At (the decrease of temperature per 1000 metres), at
least within the most reasonable and probable limits of At. He also shews that,
if in his theory At be assumed = 5 Cent., his Tabular Refractions agree for all
Zenith-Distances with those of Gylden.
The Pulkowa " Tabidai Refractionum " are based on Gylden's " Untersuchungen uber
die Constitution der Atmosphdre und die Constitution der Atmosphdre und die Strahlen-
brechung in derselben, St. Petersburg 1866 ?" but Gylden's original Refractions have
been diminished in the proportion of 1 - 0'00124 : 1. It seems therefore desirable
1. To confine the investigation, as we have done, to Zenith Distances not
exceeding 80 ; and then, if the results of both observatories can be
satisfactorily reconciled by reasonable corrections to the constant of
Refraction, to use the corrected places as common points of reference for
the discussion of Refractions at greater Zenith Distances.
2. To compare the observations, with the Pulkowa Tables as well as with the
Tabulae Regiomontance.
For the latter purpose a comparison between the two Tables has been made with
the following results, and the absolute terms of the equations are given both for the
Tabulae Regiomontance and the Pulkowa Tables :

It will be observed that the difference between the two Tables cannot be rigorously
represented by a simple multiple of the Refraction.
The absolute terms of the equations are thus given under four columns, viz.
I. Refractions from Tabulae Regiomontanae : Cape Observations not corrected
for R - D.
II. Refractions from Tabulae Regiomontanaj : but Cape Observations corrected
for R - D.

Thus, according to solutions I. and III.
The Refractions of the Tabulce Reyiomontance yn.t Greenwich by (1 Q'00217)
require to be multiplied 5 at the Cape by (1 0*00218)
The Refractions of the Pulkowa Tables } at Greenwich by (1 + 0-00018)
require to be multiplied j at the Cape by (1 + 0*00065)
On the other hand, according to solutions II. and IV.
The Refractions of the Tabula Reyiomontance \ at Greenwich by (1 0*00264)
require to be multiplied 5 at the Cape by (1 0'00585)
The Refractions of the Pulkowa Tables 7 at Greenwich by (1 - 0'00024)
require to be multiplied ^ at the Cape by (1 0*00303)
But as the density of the air is measured by Mercurial Barometers, and as the
effect of gravity on the mercurial column varies with the Latitude, it is necessary in
comparing the corrections of the same Refraction Tables obtained at different
observatories to take this variation of gravity into account. Professor Cleveland Abbe
has drawn attention to this (Ast. NacK. 2761), and he gives a convenient table for
the value of g at different ktitudes.
XXXV111
Taking the value of g at Pulkowa as unity we derive for
o /
Greenwich = + 51 2S'6 ; g = 0'99928
Cape ^ = - 33 56'1 ; g = 0'99775
Let r be the mean Tabular Refraction computed from the readings of a Mercurial
Barometer at any observatory.
E the Mean Tabular Refraction computed from the readings of an Aneroid
Barometer, which, if compared at Pulkowa, would be without error.
Then, if the Pulkowa Tabular Refractions are correct, the true Mean Refraction at
any other observatory will be
r = Rg,
that is to say
For Greenwich, r = R (1 - O00072).
For the Cape, r = R (I - 0-00225).
According to solution III. the above Refractions have to be increased, so that the
true Refractions become
For Greenwich, r (1 + O'OOOIS) = E (1 - 0'00054).
For the Cape, r (1 + O'OOOGo) = R (1 - 0-00160).
Similarly, according to solution IV., the true Refractions are
For Greenwich, r (1 - 0'00024) = R (1 - 0'00096).
For the Cape, r (1 - 0'00303) = R (I - 0'00528).
Thus, if solution IV. were correct the Refractions of the Pulkowa Tables require
to be diminished -j-^ - part to represent the Refractions at Greenwich, and ^-J- T part to
represent the Refractions at the Cape.
This most improbable result is due to the employment of the correction -
Z
applied experimentally to test' the legitimacy of the process.
On the other hand, when the Cape observations are reduced so that (by the
results of a curve drawn through the values of D R) the R observations are corrected
to D, and the latter are then corrected for Flexure as determined by the collimators,
XXX IX
we obtain corrections to the Pulkowa Tables for the Refractions at Greenwich and the
Cape which agree with each other within limits that may be explained by local causes,
such as the difference of the mean excess of the temperature of each observatory over
that of the outer air.
But the reasons for rejecting the method of reducing the observations to the
mean of the II and D results do not rest alone on the result of this discussion.
For the Cape observations
the Flexure correction is 0"'46 sin
R D
the conventional - - correction is + 0"'0o + 0"'47 sin
The sum of these corrections is + 0"'05 + 0"''01 sin
In other words, the reduction by the Greenwich method corresponds for the Cape
Transit- Circle with an assumption that its true Horizontal Flexure is zero, whereas it
is shewn by the collimators to be 0"'46 0"'02.
In the Cape Transit- Circle the collimators view each other through a clear
aperture in the cube, so that the instrumental result for Horizontal Flexure is
unquestionably correct within insignificant limits.
At Greenwich the correction - - sin (when the Flexure is assumed zero)
corresponds exactly with the mean of the only existing unobjectionable determinations
of Flexure, although there is also a true *R D correction of a persistent mean
character which, as Professor Turner has shewn (Monthly Notices R.A.S.,
LIL, pp. 374-78), has also a periodic variation depending on the season of the year.
This variation points still more clearly to the true origin of the R - D
discordance, viz. : the arrangement of the layers of air of different temperatures
within the Transit- Room. The far greater, amount of the R D discordance at the
Cape seems to be due' to several causes :
1. The shutter openings are only 2 feet wide, instead of 3 feet as at
Greenwich.
2. The walls are much thicker, and thus probably retain heat much longer.
3. The walls and roof are more heated by sunshine, which is far stronger and
more persistent than at Greenwich.

It should be mentioned, however, that the residuals of the four solutions are very
nearly the same, as will be seen from the following Tables :

From these residuals we have :
I. II. III. IV.
-27 3-02 -">-~ fi 4-78
Probable Error of one )
observation of weight V 1"'53 l"-49 1"'60 l"-4(i
)
Now weight unity was computed to correspond with an estimated probable error
of O y '50, whereas the value comes out in all cases about three times as great.
This points clearly to large systematic errors of which no account has been taken ;
indeed, apart from such errors, very few of the residuals ought to exceed 0"'10, as
the theoretical probable error of most of the equations, derived from the agreement
of the results inter se, is less than 0"'05.
Having regard to the accuracy with which the division-errors of the circles have
been determined both at Greenwich and the Cape, it is impossible to explain the origin
of the change of sign in the absolute terms of the equations from No. 3 onwards to
No. 7, and the succeeding change of sign at; No. 8 in the Greenwich observations of
Circumpolars, or the change of sign of No. 15 in the Cape observations of Circurn-
polars by any unknown error of graduation.
A far more probable origin of these discrepancies is to be found in the effect of
the heated air in the interior of the Observatory. At Greenwich, for example, the
rays of most Stars of the two first groups enter the Transit-Room by the horizontal
shutters ; for groups 3 to 7 the rays at upper transit enter the horizontal shutters,
but at lower transit the vertical shutter ; from group 8 onwards, the rays at lower
transit enter the vertical shutter below the level of the brick walls, where the interior
air is probably warmer than that included between the sloping part of the roof. At
the Cape the rays of Stars included in group 14 enter the horizontal shutters both ut
upper and lower transit, whilst in group 15 the rays from Stars at upper transit enter
the horizontal shutters, and at lower transit the vertical shutter. If, therefore, the
temperature of the air inside the Observatory be different from that of the external
air, we have, in the different angles of incidence into this heated medium, a sufficient
explanation of the systematic errors in question.
xliii
To enable the reader to judge of the relevancy of these remarks the following
discussion of the Cape Thermometer readings may be useful :
During the directorate of Sir Thomas Maclear and Mr. Stone, the thermometer
used for the computation of Refraction was placed in a crib fixed outside the S.W.
window of the Transit-Room, so that it could be read through the window. By
comparison with thermometers in a properly ventilated screen placed on the
lawn at the height of the pivots of the Transit- Circle, and 65 feet to the South of
the Southern Transit opening, it was found that, in consequence of radiation from
the walls of the Observatory, the thermometer readings of the window-crib were, on
the average, 1 0> too high at 10 p.m. (See Quarterly Journal of the Royal Meteoro-
hxjical Society for October 1882, and Introduction to the Cape Meridian Observations
1879-81, p. xxix.) The thermometers, both in the window-crib and screen, were
regularly recorded in order to ascertain their systematic differences.
In May 1884 a thermometer was mounted to the South-west of the Observatory
building on a site where a still more perfect circulation of the air could be secured
(at the Cape the winds are almost invariably either S.E. or N.W.). In September 1884
thermometers were also suspended at points in a plane 2 feet East of that described
by the col limation- axis of the Transit-Circle, and at the same distance and altitude
from the axis as the object-gla.ss when the instrument is directed to 70 Z.D. North,
to 70 Z.D. South, and to the Zenith. These thermometers are subsequently described
as North, South, and Top, respectively.
The separate readings of the thermometers will be found in the Introduction to
the Cape Meridian Observations 1882-85, pp. 84-135, for the whole period covered
by the N.P.D. observations of the present Catalogue, viz., 1880 March 31, to 1885
February 3.
To render the discussion more complete, the thermometer readings 1886-88 have
been included, and the results are given below. All observations made by day
are excluded, because the Catalogue places depend almost entirely on observations
made by night, and the relation of external to internal temperature is reversed
by day.
The Barometer is fixed to the south wall of the Transit-Room, the bulb of its
attached thermometer is plunged in the mercury-cistern of the Barometer, and is
4 feet west of the centre of the transit-opening, and 2 feet below the level of the
transit-axis.

These results are all corrected for the index-errors of the thermometers employed.
It is evident from the above
1. That for observations at night the temperatures recorded in the window-crib
are in the mean too high by 1'0, in consequence of radiation of heat from
the walls of the building.
2. That the temperature of the air in the immediate neighbourhood of the object-
glass, notwithstanding the free draught of air in the room, is on the average,
for night observations, about 2'2 higher than that of the external air.
3. That this excess of internal temperature is rather greater towards the North
than towards the South, probably because the North wall is exposed to the
direct rays of the Sun, and it thus absorbs more heat during the day than
the South wall.
4. That below the level of the bottom of the vertical shutter opening, the internal
temperature (as shewn by the attached thermometer) is on the average
3'4 higher at night than the external temperature.
5. That there is no practical difference between the temperature of the air at
night, as shewn by the external thermometer, whether it is mounted on the
lawn or at the South- West corner of the Observatory.
xlv
That somewhat similar conditions exist at Greenwich is shewn by Table III. of
Professor Turner's paper, On the distribution of Temperature in the, Transit-Circle
Room at the Royal Observatory Greenwich (Monthly Notices, Vol. LIL, p. 426). Having
regard to these facts it is not difficult to assign a probable source of the systematic
eiTors in the observations both at Greenwich and at the Cape on the grounds already
stated. To this source of error may be added the possibility of small errors of Flexure
of the tube and circle which do not follow the adopted law of sin , and for the
detection or elimination of which no means exist at either observatory.
Rejecting, therefore, the system of correction to
4- D
, and adopting as definitive
the results of solution L, and dividing the results according to Right Ascension as
well as Declination, we get for the Stars observed both at Greenwich and the Cape
the following results, which do not exhibit any well marked periodic character in
the Refraction depending on the seasons :

As an independent control on the system of Declinations a number of pairs of
Stars was selected for observation with the Zenith-Telescope, and a list of these pairs was
forwarded to Dr. Otto Struve with a request that the Northern Stars of the list should
be observed at Pulkowa, either by referring them to the Pulkowa Standard Stars with
the Transit-Circle, or observing them fundamentally with the Vertical-Circle.
xlvi
Dr. Struve expressed the opinion that for such work he considered the Vertical
Circle should be employed, that Dr. Nyren was unable to undertake observations of the
complete list with the Vertical Circle, but had promised to observe a list of 22 Stars of
special importance, and he hoped that Dr. Romberg would be able to observe the others
with the Transit-Circle.
These 22 Northern Stars were selected in such a way that for each of eleven Southern
Circurnpolars there should be one Northern Star forming a Talcott-Latitude pair with
it at upper and another at lower culmination. The 22 Talcott pairs * thus formed
were observed with the Zenith- Telescope at the Cape, and the 22 Northern Stars were
observed by Dr. Nyren with the Vertical- Circle at Pulkowa. The results of Dr. NyreVs
observations were kindly communicated by him on the 9th March 1889, and are also
published in the Astronomische Nachrichten, No. 2904.
In the mean of two Latitude pairs, in one of which the South component is a Cir-
cumpolar Star at upper transit and in the other pair the Southern Star is the same
circumpolar at lower transit, it is clear that the mean Declination of the South Stars
(apart from change of Latitude between the observation of the two pairs) must be
rigorously = 90. The deduced Latitude from pairs thus combined will therefore
rest entirely on the Pulkowa Declinations, and be independent of errors in the assumed
places of the Southern Circunipolars.
The following are the mean results ; they are based on four observations of each
Northern Star at Pulkowa, and on 10 to 12 observations of each pair with the Zenith-
Telescope at the Cape. The Cape Observations extend from 1886 to 1891, and the
effect of change of Latitude is practical ly eliminated, as is shewn by the results with and
without Chandler's corrections for change of Latitude :

This discordance of 0"'ll between the Latitudes of the Cape deduced on the one
hand by Zenith-Telescope observations at the Cape, combined with Vertical Circle
observations at Pulkowa, and on the other hand from Transit-Circle observations at
Greenwich and the Cape, may be due in great part to the accidental errors of the
various operations involved. But as the Pulkowa observations extend over a short
period of time, it is possible that the results may, to a sensible extent, be affected,
even in the mean, by change of Latitude. It is also possible, having regard to the
considerable systematic errors exhibited by the residuals in the circumpolar
observations, both at Greenwich and the Cape, that the mean values of the Latitudes
of both Observatories may be sensibly affected by the systematic difference between
the external and internal temperature, and by the irregular distribution of temperature
within the Observatory itself.
The general conclusions which result from this discussion are :
1. That no results of the highest refinement, either in Right Ascension or
Decimation, can be obtained with a non-reversible instrument.
2. That if the errors of the micrometer-screws and the division-errors of circles
are accurately known, the employment of Reflex observations tends to increase the
systematic errors of the resulting Declinations, unless the external and internal
temperatures are perfectly equalized.
3. That even Direct observations are materially affected by the difference between
internal and external temperature, for in no other way can the outstanding errors of
the Greenwich and Cape Circumpolar observations be explained.
4. That to minimize such errors the construction of the observatory should be
perfectly symmetrical with the instrument, that is to say, the roof should be a semi-
cylinder whose axis is concentric with that of the Transit-Circle. The roof and walls
of the observatory should be made of double sheets of iron, with a well ventilated
air-space between the sheets, and the whole should be protected from direct sunshine
by louvres (say of sheet-iron, painted white). The observing opening should be
as large as can be conveniently employed. The observatory should be raised by
pillars a few feet from the ground to allow free circulation of air underneath, and the
floor be made of thin ribbed iron plate, such as is used in the engine-rooms of steam
ships.
Several of these conclusions have been already anticipated in the Introduction to
the Cape Meridian Observations 1879-81, p. xxx.
The systematic corrections contained in the Tables facing page 1 should be applied
to the Catalogue, but except for the discussion of Refractions at low altitudes, it is not
desirable to use the Catalogue places North of Declination + 40.

INTRODUCTION TO APPENDIX I. (p. 101).
Results of Fundamental Observations of Southern Circumpolars.
In the Southern Hemisphere the nearest Star to the Pole which can be observed in
daylight at lower transit is ft Hydri, and its Polar Distance of 12 is much greater
than is desirable for the accurate determination of fundamental Azimuths It is
therefore necessary, during the winter months, to begin observing Circumpolar Stars us
early as possible in the evening twilight, and again to observe the same Stars at opposite
culmination in the early morning. This was done in the years 1881, 1882, 1884,
1886 and 1887.
Except for a Octantis it was not found possible to obtain double transits of close
Circumpolars between o h - to 7 h - of R.A. and between 17 h - and 19 h - of R.A. In 1888
observations were made to determine the positions of the outstanding Circumpolars by
single transits, the Azimuth of the Transit-Circle being derived from observations of
four Circumpolar Stars on each night (two above and two below pole) whose places had
been fundamentally determined in the immediately preceding years.
The results of all the Fundamental observations of Circumpolar Stars thus obtained
are given in this Appendix, and they have been employed as the basis of the Azimuths
of the Meridian Observations for the Cape General Catalogue 1890. In general, the
N.P.D.'s of this Catalogue are independent of error of Latitude, because they rest on
an equal number of observations at upper and lower transit (in some cases on three or
more consecutive transits). When theN.P.D. does not rest exclusively on consecutive
upper and lower transits, the result is given to one place of decimals only and the
Mean Date is included in brackets, and is merely taken from the General Catalogue.
INTRODUCTION TO APPENDIX II. (p. 105).
Meridian Observations of a and ft Centauri.
These observations were made solely for the purpose of providing data to determine
the motions of a. 2 and ^ Centauri relative to /3 Centauri. The observations have
simply been abstracted from the journals and reduced to 1885'0 without corrections
for Orbital Motion, Proper Motion, Parallax, Flexure, or error of Latitude.

* For most practical purposes the corrections to the Catalogue places for Stars between Dec. 70 and 90 may
be taken as the mean of the corrections for Upper and Lower Transit. Rigorously, of course, these corrections should
be combined in proportion to the number of Upper and Lower Transits.
