Introduction. 11 These quantities have been laid down in the last two diagrams of the Plate, and the corresponding curves drawn, representing the systematic discordance between the R.A.'s above and below the Pole, as depending on the R.A. and IST.P.D. of the star respectively. II. Formation of Mean North Polar Distances. In the first place the mean N.P.D.'s of the several Annual Catalogues 1877-1882 have been corrected to reduce them to the standard flexure, R — D, and thermometer corrections, used in the years 1883-1886. (1.) Corrections have been apphed to the refi-actions in the years 1877 and 1878 on account of an index error of — 0°'7 in the exterior thermometer (as determined by comparisons with the Standard on 1879 April 3). The Thermometer readings from 1879 January 1, had already been corrected for this error, although it might appear from the Introduction to the Greenwich Observations for 1879, p. Ixxvi., that this correction had not been applied to the observations before 1879 April 3. (2.) Corrections to eliminate ■ the flexure correction applied in 1877, 1878, and in the first four months of 1879 (to April 19") have been applied to the N.P.D.'s. (3.) Corrections have been applied to the N.P.D.'s in the years 1877-1882 to reduce them to the same system of R — D as that used in the years 1883-1886. A change in the mounting of the Collimators, made in 1882 June, considerably extended the range of stars available for observation by reflexion : and the results for R — D in subsequent years have shown a close accordance. The following are the formulae found in the separate years 1877-1886 as given in the Annual Volumes : — Year.

It has been assumed that the constant term is in each case applicable to its own year both for the four years 1883-1886, and for the earUer years 1877-1882. But as regards the variable term, it is assumed that the mean of the closely accordant results for 1883-1886, viz., + l-"225 x sin Z.D., is applicable to the whole ten years 1877-1886. In support of this view it is to be remarked that no constructive change was made in the instrument itself during the ten years : and that the mean value of the co-efficient of an assumed variable term depending on Sine Zenith Distance simply is + 0"-69 for the years 1877-1881, while that deduced from observations of stars in the years 1883-1886 within the limits of zenith distance available in the earher years is -f- 0"'89, not very different from the former, especially when it is remembered that the extension of the available range of stars in 1882 (consequent on the alteration in the mounting of the collimators) probably affected the distribution of stars observed at small zenith distances. For the convenient application of these three sets of corrections, tables have been formed for each year, with argument N.P.D., representing the sum of the corrections applicable to the observations in that year. The mean N.P.D.'s. of the various printed Annual Catalogues were then corrected by the help of these tables. Another set of corrections, affecting indiAddual stars only, has been apphed to the refractions, in cases where the exterior thermometer had not been read sufficiently near the time of observation of the star, and where a correction to the adopted reading could be advantageously inferred from the photographic registers of the Meteorological Department. A complete list of these alterations and of the resulting corrections to refraction, which are in general small, is given in Appendix III. to the Greenwich Observations for 1887. The finally corrected Annual Means have been used in the formation of the " Mean N.P.D. 1880-0," to which the same statements apply generally as have been made for K..A., omitting all that relates to correction for equinox. The adopted Co-latitude is 38° 31' 21"-90 throughout. The corrections required for orbital motion in the case of Sinus and Procyon are given in the Errata. A discussion of 6,749 observations above, and 4,649 below the Pole of 690 stars, is printed in Section IV. of this Introduction. All such observations of stars whose N.P.D. does not exceed 41° 30' are considered available for determining the correction to Co-latitude. In the following table the means of groups of every 50 stars, to N.P.D. 41° 30', have been taken (that is of every 5 groups of the Table in Section IV.), except for the last group, which consists of 30 stars only. The Introduction. 13 ^' Mean N.P.D. of group " is the simple mean of the N.P.D.'s of all the stars in the group ; but the " Mean Excess of N.P.D." is the weighted mean, weights beiilg assigned according to the Table in Section IV.

Explanation of the Separate Columns of the Printed Catalogue. The formulae by which the various numbers have been prepared will be described under these explanations. The " No." is the ordinal number of this Catalogue, the stars being arranged in order of R.A., 1880*0. The " Star's Name " is taken from one of the following authorities, the order of preference being the order of mention of the authority below : — 1.

C." ; in the Cape Catalogue for 1880 ; or in the Harvard " General Catalogue of 4,260 Stars, with their Approximate Magnitudes, reduced to the Epoch 1880," referred to as " H. P." The " Magnitude " is taken from the Harvard Photometry for stars contained in that vfork, and for other stars (marked *) from the Bonn Durchmusterung. For the few remaining stars (marked f ) the authority for the magnitude is given in the Notes. The magnitude in the Uranometria Nova Oxoniensis is given in the Notes for all cases in which it differs by more than 0"2 magnitude from that in the Harvard Photometry. The magnitudes of the components of double stars, taken from Struve's Mensuroe MicrometricoB or other authority, are given in the Notes. In the case of Variable Stars, the limits of magnitude and the period given in the Notes are taken from Mr. Chandler's Catalogue in the Astronomical Journal Nos. 179, 180. The formation of the " Mean R.A., 1880-0," has already been explained. The computations were made singly, and carefully examined. The " Mean Date " is expressed in years and decimals of a year reckoned from 1800. The " Number of Observations " gives the aggregate number of all the observations in the different years, above and below the Pole respectively, these being combined with equal weights to form the Mean Right Ascension last mentioned. Introduction. 15 The " Annua;! Precession, 1880-0," and the " Secular Yariation 1880'0," have been computed by the help of Fohe's " Douze Tables pour le calculdes reductions etelMires," in which Struve's Constant of Precession is used. The Precession is given by the formula — 38-0723 + i''3369 [log. = 0-12611] sin R.A. cot. N.P.D. and the Secular Variation by the formula — A + B cot N.P.D. + C cot^ N.P.D. where — A = 0^-00190 + 0^-00650 sin 2 R.A. B = —0^-00057 sin R.A. + 08-02987 cos. R.A. C = +0^-01300 sin 2 R.A. The second term of the precession is readily computed from these tables, and the quantities A, B, C, are therein tabulated for every minute of E.A. These formula correspond essentially with those used in previous Catalogues,' but the method of computation is simpler. The R.A. and N.P.D. are taken for I880'0 to 1^ and 0'*1 respectively, except for stars within 10° of the Pole, for which more accurate places were computed. The calculations were made in duphcate and carefully compared. The " Annual Proper Motion, 1880-0," has been taken from Auwers' " Neue Reduction der Bradley schen Beobachtungen " or his " Catalog der Fimdamental Sterne," for stars contained in either of those works. The authority for other proper motions is given in the Notes. The process for forming the " Mean N.P.D., 1880-0 " has been explained. The , numbers were computed singly and carefully examined. The " Mean Date " is expressed in years and decimals of a year reckoned from 1800. For Circumpolar Stars the weights mentioned in the next paragraph were used in forming this mean. The " No. of Observations " is the aggregate of all the observations in the different - years, above and below the Pole respectively, these being combined to form the Mean N.P.D. just mentioned, with weights as follows : For stars whose N.P.D. does not exceed 15°, the observations above and below the Pole are considered equally good; from J^.P.D. 15° to N.P.D. 36°, those below the Pole have the weight f for 16 Greenwich Ten-Year Catalogue of Stars for 1880. each observation ; from N.P.D. 36° to N.P.D. 41°, those below the Pole have the weight ^ ; beyond 41° N.P.D. the observations below Pole are not used, and in the case of stars observed below Pole only, the mean result is enclosed withim brackets. The " Annual Precession, 1880-0," and the " Secular Variation, 1880-0," have been computed by the help of FoHe's Tables referred to above. The precession is given by the formula — — 2o"-o542 cos R.A. which is taken directly from the Tables, and the Secular Variation by the formula — A' + Bi cot N.P.D. where — A' = + o"-oo86 cos R.A. + o"-4.48o sin R.A. B' = + o"-i95o sin- R.A. The quantities A-' and B^ are given directly in the tables for every minute of R.A. The R.A. and N.P.D. are taken for 1880-0 to 1^ and O'-l respectively, except for stars within 10° of the pole, for which more accurate places were computed. The calcu- lations were made in duplicate and carefully compared. The last two columns contain references to two other Catalogues of Stars, viz. : Auwers' edition of Bradley, and the British Association Catalogue. It is to be remarked that the date given in the heading refers to the Epoch of the Catalogue, and not to the year of publication. The titles and places of publication of the Catalogues adopted for reference are as follows : — AuwBES' Bradley. — "Neue Reduction der Bradleyschen Beobachtungen, Erste Abtheiltmg, Catalog von 3268 Sternen ftir das .^quinoctium und die Epoche 1755-0.

British Association Catalogue.— The Catalogue of Stars of the British Association for the Advancement of Science, containing the Mean Right Ascensions and North Polar Distances of 8,377 Fixed Stars, reduced to January 1, 1850, together with their Annual Precessions, Secular Variations, and Proper Motions, as well as the Logarithmic Constants for Computing Precession Aberration, and Nutation. With a Preface explanatory of their Construction and Application, by the late Francis Baily, Esq., D.C.L., &c., London, 1845. As a security against mistakes of a large amount, the R.A. and N.P.D. of tlie Catalogue have been compared with the approximate R.A. and N.P.D. for 1880, computed from former Catalogues to 1^ and O'-l respectively, for use in the Calculation of the Precessions. The proof sheets have nlsu been compared with the Radcliffe Annual Catalogue for 1880 ; the Washington Annual Catalogue, 1880 ; and witli Stone's Cape Catalogue, 1880. Introduction. 17 IV. — Comparison of the Places of Circumpolar Stars as observed above and below the Pole, from Observations made in the Years 1877 to 1886. The following tables show the mean excess of E.A, and of N.P.D. above Pole for all stars in the Ten- Year Catalogue of which observations were made both above and below the Pole. The star is designated by its No. taken from the Ten- Year Catalogue. The figures on the same line as the No. refer to the observations above Pole ; those on the next line to the observations below. The excess of E.A. is multiplied by Sin N.P.D. in all cases, to reduce it to equatorial interval. The weights assigned to each star are computed as follows : — For R.A. if TO and n be the number of observations above and below the Pole respectively the weight assigned is -^ The maximum weight for any star is thus 20, which corresponds to an infinite number of observations above and below the Pole ; and the expression is equivalent to that for N.P.D. for stars at about 30° from the Pole. . '■ For N.P.D. the weights used are determined by use of the " Probable Errors of Greenwich Observations in Zenith Distance," given by Mr. Stone in the Monthly Notices of the Royal Astronomical Society for 1869 June 11, page 324. Putting n for the number of observations of a star above pole, e for the probable error of one observation ; Wi and e^ the similar quantities for the observations below pole ; e^ the probable systematic error afi'ecting aU observations of the same star, and depending on outstanding division error, uncertainty in the constant of refraction, &c. ; the formula employed to determine the weight to be given to that star is ^ „ , ^^2,9^^ ^a or assuming eo^ = fV ^^) which would make Cq = 0"*16, the weight becomes — j — ^^\ J which has been adopted for use in the investigation.
