Price Six Shillings and Sixpence, . tr? ASTRONOMY INTRODUCTION TO THE GREENWICH SECOND TEN-YEAR CATALOGUE OF 6892 STARS, FOR THE EPOCH 1890-0. THE results contained in the following Catalogue are derived from observations made with the Transit-Circle in the years 1887 to 1896. The year 1890 has been adopted for the epoch as being near the mean year of the observations, and more convenient for reduction to other epochs than the actual mean year. The stars contained in the Catalogue may be classified as follows : (i.) Fundamental Stars. These include Greenwich Clock Stars, 9 Azimuth stars, and the stars in the Nautical Almanac and other Ephemerides. Altogether, 843 stars of Professor Newcomb's Catalogue of Fundamental Stars for 1875 and 1900 are contained in the present Catalogue. These stars have been generally well observed, especially those of the Greenwich Clock Star list, of which the number of observations is usually 50 or more. (ii.) Stars contained in Groombridge's Circumpolar Catalogue, 1810. Of the 4243 stars in Groombridge's Catalogue, 3645 are contained in this Catalogue, and the remainder, with-few exceptions, have been observed in the preceding Ten-Year or Nine- Year Catalogues. (iii.) About 1500 stars, brighter than the 7th magnitude, and beyond the limits of N.P.D. of Groombridge's Catalogue. These include Zodiacal stars, Southern stars observed for refraction, and stars used for determination of zenith point. With these may be included 340 Piazzi stars. (iv.) About 700 or 800 stars, mostly faint. The positions of these stars were required as guiding stars for the Astrographic Equatorial, comparison stars for Comets, or stars which had been occulted by the Moon. The total number of Bradley stars observed is 1817, of which number 466 are also Groombridge stars. 701273 GREENWICH SECOND TEN- YEAR CATALOGUE or STARS FOR 1890. Attention is drawn in this Introduction to various observations made chief}} 7 during the years 1887 to 1896, with the view of investigating the peculiarities of the instrument ; and the results are collected as showing to what extent the Catalogue is free from, and to what extent it may be liable to, systematic errors. I. RIGHT ASCENSIONS. Collimation Error. The position of the line of collimation is determined each day by observations on the collimators, the reading of the micrometer of the north collimator for coincidence of its nearly vertical wire with that of the south collimator being obtained by observations made through the central cube of the transit-circle. The mean of the observations is taken for each week, and a correction of + r- 008 ( = 0"'30), determined from observations made in the years 1871 to 1880, has been applied in forming the adopted reading of the line of collimation on account of the difference of the readings for coincidence of the collimators, according as they are viewed through the central cube or with the instrument raised. The readings for coincidence of the collimators are given in the Greenwich Obser- vations in the section " Transits." Once each week these observations are made both through the central cube and with the instrument raised, the latter being marked with the letter R. The differences between these nearly simultaneous readings for coinci- dence, as obtained by all the observations of each observer, give the following corrections to the collimation error derived from observations through the central cube for each of the years 1887 to 1896: Excess of Collimation Error ivhen the observation for coincidence of collimators is made with the instrument raised, over that obtained when the observation is made through the central cube.

(See discussions by Professor Turner in the Monthly Notices of the Royal Astronomical Society, vols. xlvi. and lii.) In order to eliminate personality depending on the direction of measurement, a reversion prism, eye-piece has been frequently used in determining the readings for collimation, three bisections being taken with the direction of increasing readings apparently towards the right (r), and three towards the left (1).

The error of level has been determined by observations on the nadir, using the value of the collimation reading adopted for each week. The observed and adopted values are given in the Greenwich Observations. The apparent correction to the adopted level errors derived from reflexion observations of right ascension are collected for each year in the "Transit-Circle tables" in the Greenwich Observations. These corrections for the ten years 1887 to 1896 are : 6 GREENWICH SECOND TEN- YEAR CATALOGUE OF STARS FOR 1890.

The apparent errors of the pivots given in the annual volumes, taken over the mean range of Z.D. in which reflexion observations are made, would give corrections to the level of + 0"'12 for north stars, and +0"'03 for south stars. Diurnal Variations of the Level Error. Observations taken in the years 1895 to 1899 show a diurnal change in the level error, the level error within three hours of noon or midnight being greater than that determined about 6 p.m. The following tables, derived from observations on all days on which three or more determinations of level were made, have been found by grouping the observations made between 21 h and 3 h , and 9 h and 15 h , and exhibit the apparent corrections to level about the time of sunset.

The stars Polaris, S Ursae Minoris, Cephei 51, and X Ursse Minoris were used for determination of azimuth error. The observations of these four stars were only kept for place when the azimuth error was determined by consecutive transits of one of the stars at upper and lower culmination. As consecutive transits of Polaris at upper and lower culmination are observed much more frequently than those of the other polars, the right ascensions of these stars depend essentially on double transits of Polaris. This absolute method of determining the azimuth error assumes the stability of the instrument for 12 hours; but the diurnal change in the level error (p. 6) and the discordances between the right ascensions of the close polars, determined from observa- tions at upper and lower culmination respectively, exhibited in the following table, indicate that there is a diurnal variation in the position of the pole of the instrument.

Clock Error, The right ascensions of the clock stars adopted each year are given in the Introductions to the Greenwich Observations. For the years 1887 and 1888, the right ascensions of the clock stars depend on the Standard Right Ascensions of the 1872 Catalogue, for the years 1889 to 1B92, on the Standard Right Ascensions of the 1880 Catalogue, and for the years 1893 to 1896, on the right ascensions of tie 1890 Five- Year Catalogue, using Struve-Peters' value of the constant of precession, and the Auwers'-Bradley proper motions. Equinox Correction. From the discussions of the position of the ecliptic in the Greenwich Observations, it appears that the right ascensions of the Clock Stars in the ten years 1887 to 1896 require the following corrections : s 1887 0-046 1888 +0-072 1889 +0-024 1890 +0-093 1891 +0-088 1892 +0-040 1893 +0-090 1894 +0-042 1895 +0-027 1896 +0-040 The mean of these is + 8> 047, but no correction has been applied, as the uncertainty of the system of proper motions based on Bradley's equinox, and of the observations of the Sun due to the personality of the observers, leaves the determina- tion of the equinox somewhat arbitrary. The equinox of this Catalogue, therefore, is that of the 1872 Catalogue carried on by the use of Struve-Peters' precessions and Auwers'-Bradley proper motions. As in the Nine-Year Catalogue (1872), and the Ten-Year Catalogue (1880), a separate determination of the right ascensions of the clock stars has been made, in which only those observations are included where the group of clock stars extended over 12 hours at least. The total number of observations of clock stars (from Six-Hour groups) is 12,599, and of this number 6128 are derived from Twelve-Hour groups. From these data corrections have been determined to reduce the right ascensions of the Catalogue to those of the Twelve-Hour groups taken as standard. The following table exhibits the excess of the R.A. from the Twelve-Hour groups above that of the Catalogue for each star, together with the number of observations. The weights are computed from the formula ^T^> where m and n are the numbers of observations in the Twelve-Hour groups and in the Catalogue respectively. INTRODUCTION.

In the column " Adopted Correction " of the above table is given a smoothed coTre-c- tion derived from the mean excesses for each hour. This correction has been applied to the right ascensions of the Catalogue to obtain the Standard Right Ascensions of the clock stars for 1890-0. In forming these Standard Right Ascensions, no correction has been applied for the differences depending on north polar distance. Neither of these corrections has been applied to the right ascensions of the Catalogue itself. The practice of basing the right ascensions of the clock stars on the Twelve- Hour groups was introduced at Greenwich in the Nine-Year Catalogue for 1872. The following tables and the corresponding diagrams of the frontispiece show the effect of this process in eliminating the systematic errors of the places of clock stars derived from the earlier catalogues. The mean corrections to the right ascensions of the First Seven-Year Catalogue (1860) and of the Second Seven-Year Catalogue (1864) are obtained from the introduction to the Nine-Year Catalogue (1872), p. 8, and to the other Catalogues from the direct comparisons with the Twelve-Hour groups given in the introduction of each Catalogue.

The Standard Right Ascensions of the clock stars for 1890-0 based on Twelve-Hour groups are given on p, 64. The differences between the Twelve- Hour and Six-Hour groups are now so small that they can no longer with certainty be attributed to errors in the Six-Hour groups. An independent verification of the accuracy of the Greenwich fundamental right ascensions is afforded by the following comparison between Newcomb's Fundamental Catalogue and the 1880 Ten-Year, 1890 Five-Year and Second Ten-Year Catalogues, the small differences in order of R.A. being entirely of an accidental character.

II. NORTH POLAR DISTANCES. Microscope-Micrometer Screws.- New steel screws were applied in 1886, and three of them were reversed to eliminate the effects of wear. The errors of the mean readings of the six microscope-micrometer screws, as determined in 1886 when the screws were new, in 1893, and in 1896 November, were as follows: Error of the Revolutions of the Screws.

Division Errors. Redetermination of the division errors for every 5 and every 1 were made in 1898, to supplement those made in 1851, 1856, and 1871. The discussion of these observations is given in the " Transit-Circle Tables " in Greenwich Observations (1897). The differences between the newly adopted values of the division correction and those previously in use were applied to the means in forming the N.P.D.'s of the Catalogue. The following table gives the values of the correction for division error resulting from the discussion in 189K, and also the corrections to the values previously in use.

Nadir Correction. The apparent correction for discordance between the zenith point, determined from observations of the nadir and from reflexion observations of stars in the years 1887-1896, are as follows : 1887 +0-01 1892 0-25 1888 0-12 1893 0'34 1889 +0-07 1894 0-27 1890 +O-08 1895 O-3I 1891 +O-07 1896 O'34 It may be noticed that the object-glass was repolished and a new telescope- micrometer screw introduced in 1891 October. No correction has been applied on account of these discordances. It should be observed that the adopted zenith points depend essentially on the reflexion observa- tions of stars, and that this discordance only enters into the observations on those nights when no reflexion observations are obtained. As will be seen in the next paragraph, there appears to be a diurnal variation in the nadir, and it was considered possible that, as the reflexion observations were usually made soon after sunset, while the observations of the nadir were made at all hours, such a diurnal variation would to some extent account for the above discord- ance, but this was not found to be the case. Diurnal Variations of the Nadir. Observations taken in the years 1895 to 1899 show a diurnal change in the position of the nadir, the observations taken about noon and midnight giving positive corrections to the observations made near the time of sunset. The observations were grouped as in the case of the levels (see p. 6), and the results for each month from 1895 July, from which date three observations of nadir were taken regularly on fine days, to 1899 December, are given in the following tables, and exhibit the apparent corrections to the nadir about the time of sunset.

A number of special observations have been made to obtain information as to the cause of this discordance. A series of observations were made between 1893 December 3 and 1894 April 22, in which the direct observation was taken immediately before the observation by reflexion instead of after it. A discussion of these observations and of others relating to the R D discordance by Professor Turner and Mr Thackeray is given in the Memoirs of the Royal Astronomical Society, vol. li. The following table showing the results of this series of observations is taken from the Introduction to Greenwich Observations, 1894, p. cxli., where the results of the separate observations are given.

Another series of observations was then made from 1895 to 1898, in which the R and D observations of pairs of stars were made alternately on alternate nights. The results of these observations which are given in the following tables do not support the previous conclusion, but show a fair agreement with the observations made in the usual way, both when the discordance was large, as in the years 1895-1896, and when it was small, as in the years 1897-1898.

These observations, arranged according to the reading of the thermometer at the time of observation, show a variation in the flexure corresponding generally to the annual variation in the R D discordance (see Monthly Notices, R. A. S., vol. Hi. p. 374). 22 GREENWICH SECOND TEN-YEAR CATALOGUE OF STARS FOR 1890. Value of Flexure found from observations in 1893, arranged according to Temperature at the time of observation.

The resulting values of the flexure were + 0"'05 and + 0"'24 respectively. (Greenivich Observations, 1894, pp. cxxviii.-cxxx.) No correction for flexure has been applied, the flexure correction being virtually included in the R D correction. Thermometer. The thermometer used throughout the ten years 1887-1896 as the exterior thermometer is Negretti and Zambra No. 45357. It is mounted on the north front of the Observatory, where it is carried by an arm projecting from the wall at a distance of 4^ feet, at a height of nearly 7 feet from the ground. It has been compared at intervals with the Standard Thermometer, and as a result of these comparisons, a correction, 0'l, was applied to its readings from 1887 to 1894, and 0- 2 for 1895 and 1896. On 1896 July 18 a thermometer was mounted in the Front Court in a screen allowing a free circulation of air. Comparisons of this thermometer with Negretti and Zambra No. 45357, given in the Transit-Circle Tables of the Greenwich Observa- tions, 1896 and 1897, show that the mean readings of these two thermometers agree closely for the times when the observations of stars are generally made. Barometer. The barometer in use is one made by Home and Thornthwaite marked No. 389, with metallic scale and graduation modified for change of mercury surface in the cistern. From comparisons with the Standard Barometer, it is found unnecessary to apply any index correction to the readings of this barometer. Colatitude and Refraction. The value of the colatitude adopted in the formation of this Catalogue is 38 3l'2l"'90. The refractions used are those of Bessel's Tabulse Reyiomontanse. By adopting this colatitude and refraction, continuity with the Ten-Year Catalogue for 1880 has been preserved. The material of this Catalogue is well suited for the discussion of refraction owing INTRODUCTION. to the large number of circumpolar observations, and the number of stars it contains in common with the Cape Catalogue for 1890. Taking the observations of Greenwich circumpolar stars first, and using the results given on p. 32, the following table exhibits the discordances in order of N.P.D. of the circumpolar observations with Bessel's and the Pulkowa refractions respectively. A comparison of columns 2 and 8 shows, on the whole, a better accordance when the Pulkowa refractions are used. Comparison of North Polar Distances from Observations above and below Pole.

With regard to the comparison with the Cape Catalogue for 1890, those results for the Cape were used which are given under the heading of "Sees, of Final Dec.," and depend on the following basis : (Cape Catalogue, 1890, p. xxiv.) (i.) Colatitude, - 33 56' 3"'45. (ii.) Refractions of the Tabulte Regiomontanse diminished in the ratio 1 '00218. (This diminution of the constant makes the refractions used agree nearly with those of the Pulkowa tables.) (iii.) A flexure correction of 0"'30 sin z obtained by observations on the collimators, but not supported by the R D observations. 24 GREENWICH SECOND TEN- YEAR CATALOGUE OF STARS FOR 1890.

The repetition at 60 apart would seem to point to division error remaining in the Greenwich or Cape Observations. INTRODUCTION. 25 To these data for the discussion of refraction should be added the observations of the Sun at Greenwich. The corrections to the adopted colatitude 2l"'90, using Bessel's refractions (the values of z found in the ecliptic investigations in the Greenwich Observations), are as follows for the years 1887 to 1896 : 1887 +0-08 1888 +0-09 1889 +0-06 1890 o-io 1891 o - oy 1892 +0-20 1893 0-05 1894 0-32 1895 +0-14 1896 o-oi The mean of these corrections is zero, giving a colatitude of 21 //- 90, while the circumpolars from to 40 give a colatitude 2l"'92. Had the Pulkowa refractions been used ; the colatitude derived from the observations of the Sun would have been 22"'14, while the circumpolar stars would have given 21 //> 75. (Memoirs R. A. S., vol. liii. pp. 159-161.) From this discussion it is apparent that the Pulkowa refractions, as compared with Bessel's refractions, produce greater accordance between the Greenwich circumpolar observations and, what is of very great weight, a remarkably good agreement between the Greenwich and Cape observations : they introduce, however, an unexplained dis- cordance into the Sun observations. The following table is given to enable those who may wish to do so, to substitute the Pulkowa refractions in the north polar distances. In the case of circumpolar stars, the corrections above and below pole should be combined according to the number of observations above and below pole, remarking that for observations below pole full weight is given as far as N.P.D. 15 ; from 15 to 36* N.P.D. f weight; from 36 to 41 \ weight; and below 41 N.P.D. the observa- tions below pole are not used.

The probable error of the Greenwich observations in right ascension is given in a paper by Dr Downing in the Monthly Notices, R. A. S., vol. xlix. p. 359. This table, supplemented by a determination from the star ledgers for the year 1894, shows that the probable error of an observation of right ascension is O s> 033 cosec. N.P.D. between the limits of 70 and + 70 Z.D., except near the pole where it is somewhat less. At greater zenith distances than 70, the probable error increases from O s '033 to 8 '043 at 86. The probable error of the north polar distances is given in a paper by Mr Stone in the Monthly Notices, R. A. S., vol. xxix. p. 324. The results of a redetermination made INTRODUCTION. 27 from about 3500 observations from the 1894 ledgers, supplemented by the ledgers 1887 to 1896 for low stars, together with a comparison of the values previously found by Mr Stone, are given in the following table, from which it appears that the later observations have a smaller probable error. The results have been smoothed by taking means and means again of each consecutive pair. Probable Error of an Observation of N.P.D. Z.D. N.P.D. P.E. 1894. P.E. 1869. Stone. P.E. 1894 -P.E. 1869. Z.D.

The table on pp. 39 to 44 of the Excess of N.P.D. as obtained from observations above pole, may be used to indicate the amount of error, systematic and accidental, of the observations of N.P.D. Within the limits to 30 of N.P.D., a range which involves all the division errors and a considerable change in the correction for R D discordance, the discordances have been arranged in groups corresponding to their weights. The weights are computed by the formula 2 tin. where e and e-. . ' + ne i + 2 nn-L v are Mr Stone's values taken from the fourth column of the preceding table, and e has been assumed arbitrarily as //- 16. The maximum weight given by this formula is 39. At 20 from the pole the weights given by the formula are as follows : No. of observations above pole . ,, below pole .

In the following table the weight is given in the first column, the corresponding 2 mean discordance obtained by dividing ,J by '845 (the factor for changing from mean to probable error) in the second, and in the third column the actual mean discordance obtained from the table on p. 39, the number of stars on which the determination depends being given in the fourth column.

The observa- tions with a large weight show that the systematic error is about 0"'10, instead of 0"'16 as assumed in the formula, and those with smaller weights show diminution of the accidental errors in fair accordance with the determination on p. 27. Discordances from Prof. Newcomb's Fundamental Catalogue. Before a com- parison was made between the two Catalogues, a correction of O s- 054 for difference in the adopted equinox was applied to the right ascensions of the Greenwich Catalogue, and corrections to reduce to the Pulkowa refractions and to colatitude 38 31' 21/''80 were applied to the north polar distances. The differences of right ascension are multiplied by sin N.P.D. The discordances were arbitrarily grouped in 5 classes according to the number of observations in this Catalogue, and the results are shown in the following table.

A superior limit of the systematic errors of the Catalogue is readily found by making the extreme assumption that Prof. Newcomb's Catalogue is entirely free from error, whether systematic or accidental. Taking the stars observed more than 50 times, the probable errors obtained in this way are O s '009 and 0"'12; and allowing for the accidental error of 70 or 80 observations by the table on p. 27, the systematic errors are seen to be less than O s- 008 and 0"'10 in R.A. and N.P.D. respectively. The probable error of a result derived from n observations may be taken as O s '033 2 8 '008 2 n x cosec. N.P.D. for the right ascensions, and 0"'10 2 + ~ for n the north polar distances, where e is taken from the third column of the table on p. 27. The following table giving the mean discordances between the Greenwich Ten- Year Catalogue, 1890, and those of the Aatronomische Gcsellschaft, is of interest as showing 30 GREENWICH SECOND TEN- YEAR CATALOGUE OF STARS FOR 1890. the relative accuracy of these Catalogues, as the accuracy of the Greenwich Catalogue may be considered nearly the same throughout.

CIRCUMPOLAR STARS. The full tables printed pp. 34 to 44 show the mean excess of R.A. and N.P.D. above the pole for all stars in the present Catalogue of which observations have been made both above and below the pole. In the first table the excess above pole for the right ascensions is arranged in order of right ascension. In the second table the excess above pole for the north polar distances is arranged in order of north polar distance. In each table the star is designated by its number taken from the body of the Catalogue. The weights assigned to each star are computed as follows : For R.A., if in and n be the number of observations above and below the pole respectively, the weight assigned is 4 mn The maximum weight for any m + n + i mn 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, R. A. S., vol. xxix. p. 324. Putting n for the number of observations of a star above pole, e for the probable error of one observation, n^ and e^ the similar quantities for the observations below pole, e the probable systematic error affecting all observations of the same star, and depending on outstanding division error, variation of latitude, etc., the formula employed to determine the weight to be given to that star is 4- ne? + 2 ., or assuming e 2 = A- e 2 , which would 2 make e = 0"'16, the weight becomes tv) 0& use in this investigation. + -, which has been adopted for & INTRODUCTION. 31 Mean Excess of R.A. and N.P.D. above Pole, arranged in Groups of One Hour of R.A.

Possible explanations of this are : (i.) Pivot error ; (ii.) Different character of the observation of the close polars ; (iii.) Diurnal changes in the position of the instrument. The discordances in N.P.D. for the groups of 1 indicate that the systematic errors (in which residual division errors are included) are very small, the mean value of the discordance (taken without regard to sign) for the groups from the pole to N.P.D. 30 being zt 0"'105, from which it results that the probable value of the systematic error for a zone of 1 of N.P.D. is it 0"-06 The mean value of the discordances in N.P.D. for groups of 1 hour of R.A. (taken without .regard to sign) is O'^IW, which is somewhat larger than the value for groups of 1 of N.P.D., though the weights and numbers of the stars are much larger for the R.A. groups.

COMPAEISONS WITH OTHEE CATALOGUES. Comparisons have been made between the Second Ten-Year Catalogue and the following Catalogues : The Greenwich Ten- Year Catalogue, 1880. The Greenwich Five- Year Catalogue, 1890. The Cape Catalogue for 1890. The Radcliffe Catalogue for 1890. Professor Auwers' Fundamental Catalogue for 1875. (Berliner Jahrbuch, 1890.) Professor Auwers' " 303 " Stars. (Astronomische Nachrichten, No. 2890-91.) Professor Newcomb's Fundamental Catalogue for 1875 and 1900. The Catalogues of the Astronomische Gesellschaft (as far as published). Groombridge's Catalogue, 1810. The Radcliffe Catalogue, 1845. The differences are given in the following tables, except for Groombridge's and the Radcliffe (1845) Catalogues, which will be discussed more fully at some future period with a view to the determination of the proper motions of the stars in Groombridge's Catalogue. In each of these comparisons, Struve's precession and the proper motions adopted in the body of this Catalogue have been used. The mean difference in the sense Greenwich 1890 Catalogue compared is given at the top of the comparisons in order of right ascension, and the difference for any hour is obtained by adding this quantity to the discordance for that hour. The comparisons in order of right ascension are limited to the stars within the Greenwich Clock-Star Zone i.e., 50 to 120 N.P.D. except in the case of the Zone Catalogues of the Astronomische Gesellschaft. In the case -of Professor Newcomb's Fundamental Catalogue for the comparison of the north polar distances in order of right ascension, and for the second table in order of N.P.D., as Professor Newcomb has adopted the Pulkowa Refractions for his Standard Catalogue, the Greenwich observations have been reduced with Pulkowa Refractions and the corresponding value of Colatitude 21 "'80 in order to make the observations directly comparable.

YIIL EXPLANATION OF THE SEPARATE COLUMNS OF THE PRINTED CATALOGUE. The No. is the ordinal number of this Catalogue for the stars arranged in order of Right Ascension. Columns 2 and 3 contain references to two other Catalogues of stars, viz., Auwers' edition of Bradley and the Groombridge Catalogue, 1810. The star's name is taken from one of the authorities given on the back of the title-page facing the Catalogue, the order of preference being the order of mention of the authority. The magnitudes are taken from the following sources in the order given : the Harvard Photometry (marked *) ; the Catalogues of the Astronomische Gesellschaft or the Bonn Durchmusterung (unmarked) ; Struve's Stellarum Duplicium Mensurse Micrometricss for double stars (marked t) ; the Uranometria Argentina, the Southern Meridian Photometry (Harvard), the Argentine General Catalogue, 1875, and the Cape Catalogue for 1890, and for a few stars from other authorities (marked j), the authority in each case being 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 Third Catalogue of Variable Stars (Tlie Astronomical Journal, vol. xvi. No. 379). The names of double stars the usual designations in double star catalogues are given in the notes for double or multiple stars, whether separated or not in the Transit-Circle. The Mean R.A. 1890'0 has been found by combining the results given in the Annual Catalogues of Greenwich Observations from 1887 to 1896. 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, which are combined with equal weights to form the mean right ascension. The "Annual Precession 1890'0" and the "Secular Variation 1890'0" have been computed by the help of Folie's Douze Tables pour le Calcul des Reductions stellaires, in which Struve's constant of precession is used. The precession in R.A. is given, by the formula, 3 S -0725 -f- i"-3369 [log. = 0-12611] sin R.A. cot N.P.D. ; and the secular variation by the formula, A + B cot N.P.IX + C cot 8 N.P.D., INTRODUCTION. 63 where A = c^'ooigo + o s< oo65o sin 2 E.A. B =* o s -ooo57 sin E.A. + o^ozgSy cos E.A. C = +o s -oi3OO sin 2 E.A. The second term of the precession is readily computed from these tables, aud the quantities, A, B, C, are therein tabulated for every minute of R.A. These formulae correspond essentially with those used in previous Catalogues. The R.A. and N.P.D. have been taken for 1890'0 to 1 s and 2"'0 respectively. The calculations were made in duplicate and carefully compared. The Annual Proper Motions are taken from the authorities given on p. 48. To the columns relating to N.P.D., the same remarks apply generally as in the case of R. A., except that, in combining observations above and below the pole, the following weights are used. For stars whose N.P.D. does not exceed 15, the observations above and below pole have equal weights. From N.P.D. 15 to N.P.D. 36, those below pole have the weight f for each observation ; from N.P.D. 36 to N.P.D. 41, those below pole have the weight ^ for each observation ; beyond 41 N.P.D., the observations below pole are not used in forming the Mean N.P.D. 1890'0. The "Annual Precession 1890'0"and the " Secular Variation 1890'0" have been computed as explained in the case of the Right Ascensions. The precession in N.P.D. is given by the formula, 2o"-o542 cos E.A., which is taken directly from the tables ; and the secular variation by the formula, A 1 + Bi cot N.P.D., where A 1 = +o"-oo86 cos R.A. +o"'448o sin E.A. B 1 = +o"- 1 950 sin 2 E.A. The quantities A 1 and B 1 are given directly in the tables for every minute of R.A. 64 GREENWICH SECOND TEN- YEAR CATALOGUE OF STARS FOR 1890.
