[1] STKPHKN GROOMBRIDGE. ROYAL OBSERVATORY, GREENWICH. NEW REDUCTION OF GROOMBRIDGE'S CATALOGUE OF CIRCUMPOLAR STARS. INTRODUCTION. I. STEPHEN GROOMBRIDGE. STEPHEN GROOMBRIDGE was born at Goudhurst, Kent, in the year 1755. At the usual age he was apprenticed to a linen-draper, to whose business he succeeded soon after the completion of his years of apprenticeship, and at first carried on the same business, but afterwards added that of a West Indian merchant, from which he finally retired in 1815. Having taken keen interest in astronomy from a very early age, he built for himself a small observatory at Goudhurst, where he generally resided, till his removal to Blackheath in 1802. It was not, however, till the year 1806, when 51 years of age, that lie began that series of observations which form the basis of this Catalogue by which his name is so well known to astronomers a series of observations that formed the laborious amusement of advanced age, and that constituted the outcome of a long deferred leisure which had been gained by his own untiring work. This series of observations extended from 1806-1816, and seems to have been entirely made by himself. Colonel Colby of the Royal Engineers, director of the Trignometrical Survey of Great Britain and Ireland, writes as follows : " I never was in his observatory except once, and I remember perfectly his making some multiplications of numbers consisting of three or four places of figures in a peculiar manner, setting down only the product without the .intervention of the intermediate lines to show the product by each digit separately. From these calculations he obtained the mean result to set down for the readings of the microscopes corrected for some instrumental purposes. I also remember remonstrating with him on the advantage of setting down the readings of the microscopes in their simple form, as a security against error, and I also then recalculated some of the means he had taken, using the ordinary method for multiplying, and in these cases I found him perfectly ii INTRODUCTION TO GROOMBRIDGE CATALOGUE. correct. He was so extremely anxious to make all his observations and reductions as accurate as possible that I should place great reliance on a catalogue compiled from them." Dr Firminger of the Royal Observatory, Greenwich, writes : " I saw very little of Mr Groombridge after I left the Observatory in 1807, July, and all my information of his astronomical labours has reference to a period prior to that time. His uniform practice was to write down his observations, after reading off the microscopes, upon a slate, and he usually kept two or three slates by him for that purpose, carefully examining his observations and registering them at his leisure. His observatory being close to his parlour, he frequently left his dinner, stepped into it, made his observation, noted it down on his slate, and then returned to his family and friends. He had a most accurate eye both in observing and in reading off his observation, and was one of the most accurate and expeditious men I ever saw in the manipulation of his instrument. I do not recollect him ever to have made a mistake or to have entertained a doubt on the accuracy of his observation, so far as reading off or time was concerned. With respect to the microscopes, I do not recollect anything particular in their construction, but I am certain that Mr Groombridge never asked me any question on the method of applying their readings, which he would have done had any difficulty arisen in the management of them. I have therefore no doubt but that he understood the manage- ment of them well, and that had they read off complements he would have either reduced them at the time to their first quantities or have noticed the contrary in the books wherein he has registered his observations. I do not recollect whether the micrometer heads had a single or double line of divisions. The meridian mark by which Mr Groombridge used to adjust his instrument was on the south wall of Greenwich Park ; it was too near and not well adapted for the purpose. He had not one to the south of his observatory." Mr Groombridge died at Blackheatb. on 1832, March 30, in the 78th year of his age, and left a widow, who only survived him a few years. His only child, a daughter, who was married to the Rev. Newton Smart of Farley Hospital, near Salisbury, died before her father, leaving one son, Newton Groombridge Smart. II. INSTRUMENT. Groombridge's Transit Circle was constructed by Troughton. Descriptions, illustrated by engravings, will be found in Rees's Cyclopaedia, article " Circle," and in the second volume of Pearson's Introduction to Astronomy. The telescope, 5 feet long, with an object-glass of 3^ inches aperture, crossed the middle of the axis, 3 feet wide, and passed between the two circles, which were GROOMBRIDGE'S TRANSIT CIRCLE. Ki-es's Cyclopaedia Astronomical Instruments, Plate X. ) INSTRUMENT. iii 4 feet in diameter, to the bodies of which it was attached. The axis was supported at cither end on stone piers 5 feet 4 inches high, the pivots resting in angles formed in brass work and cemented into the stone. The circles were formed principally of hollow cones fastened together by many braces of the shape of the letter X. Each of the circles had a hoop or edge bar at its back to give it strength, and was further braced by many parts which tended to unite the two together. The circles were divided into 5' divisions, and, according to Groombridge (R.A.S. Mems., vol. ii., p. 432), " having both the faces thereof divided into quadrants from to 90, the zero points being parallel to the telescope." The instrument was reversible in its Y's. Each circle was read by two microscope micrometers fixed at the extremities of two horizontal arms attached to the stone piers exactly in the horizontal diameters of the circles ; these subdivided the divisions of the limbs to single seconds, and were tin- indices by which the values of the observations were read off. Another microscope in a vertical radius of the circle passed through the lower part of one pier, and was useful for examining the accuracy of the divisions, and for detecting small motions in the more exposed parts of the instrument. The circles are divided by Trough ton as described by him in Phil. Trans., 1809, p. 115. "The operation," he says, "took place when the season of the year and the smoke of London had reduced the day to scarcely six, hours of effective light, and rather than confine my labours within such narrow limits, I determined to shut out the daylight altogether. I think I never saw my work better nor entirely to so much advantage as in this instance, owing perhaps to the surrounding darkness allowing the pupil of the eye to keep itself more expanded than when indirect rays are suffered to enter it. Now the whole of my method of dividing being performed by taking short measures with instruments which cannot themselves err in any sensible degree, and inasmuch as these measures are taken not by the hand but by vision, and the whole performed by only looking at the work, the eye must be charged with all the errors that are committed until we come to cut the divisions, and as in the last operation the hand has no more to do than to guide an apparatus so perfect in itself that it cannot be easily made to deviate from its proper course, I would wish to distinguish this from other methods by denominating it dividing by the eye." For the purposes of adjustment two screws were attached to the angles in which the pivots of the axis rested, one giving a very slow motion vertically, for the purpose of adjusting the axis to a horizontal position, and the other at the other end giving a similar motion for bringing the plane of the circle into the meridian. There also passed iv INTRODUCTION TO GROOMBRIDGE CATALOGUE. through the axis a second tube at right angles to the telescope, which contained the plumb line, by the use of which the axis was set truly level, and the reading micro- scopes were brought to show true zenith distance. . The eye-piece was movable in a horizontal or vertical direction, and readily set opposite any of the wires in a transit, or the special wires used for the observations of the vertical diameter of the sun or moon. The illumination of the wires by night was made by a lamp placed at one end of the axis, which was perforated for the purpose, and the light reflected to the eye by an illuminator placed at the proper angle in the centra ; the amount of light was regulated by varying the colour of the glasses through which it passed. There were five vertical wires, and one fixed horizontal wire for general use. That Groombridge thoroughly understood the adjustment of his instrument is manifest from the paper he communicated to the Royal Astronomical Society on the colatitude of his observatory, and which is printed in Mems. R.A.S., vol. ii., p. 432. The first object of the observer, he says, is to bring his transit instrument into the meridian, which may be effected by observations of Polaris or of other circumpolar stars, and by adjusting until they pass above and below the pole respectively at intervals of twelve sidereal hours each. This being only an approximation, the instrument may then be reversed, and the centre wires adjusted for collimation, as shown by some assumed mark at a convenient distance, by moving- the instrument in azimuth one half of the error, and the wires the remaining portion of the error. The same course of observations may then be repeated and the instrument be again reversed until the errors shall disappear in both positions, care being always taken that the axis is correctly adjusted by the level or plumb line. From the observations of high and low stars the position of the instrument as it regards the meridian may also be put to a further test, and the errors between the observed and computed right ascensions affecting both methods may be reduced to the horizon by the formula annexed to this memoir. When a transit instrument has a large circle attached thereto by means of which the zenith distance may be measured, and thence the elevation of the pole or latitude of the observatory found, the same course of reversing the instrument may be made to obtain the error of the vertical collimation, and to adjust the microscope at 90 from the plumb line, the telescope being in the horizontal position. That the adjustment of the instrument must have been carefully attended to by Groombridge on these lines is shown by the consistency of the values of "n" and of the polar point corrections. No records, however, exist of the adjustments themselves or of the times at which they were made. OBSERVATIONS. III. OBSERVATIONS (GENERAL). Roughly speaking, the number of observations made by Groombridge during the period over which the Catalogue extends is 27,000, divided as follows : 1806 I ZOO 1812 3400 1807 2050 1813 3600 1808 2400 1814 1750 1809 2950 1815 900 1810 3900 1816 zoo 181 1 4400 The Groombridge stars found in Newcomb's Fundamental Catalogue number 337, but there were very few observations of Right Ascension of these stars after the middle of 1809. There are 720 stars common to Groombridge's and Bradley's Catalogues, and these were nearly all observed before the middle of 1810. Most of the stars within 10 of the pole were observed within the first two years, and, generally speaking, it seemed as though Groombridge from time to time made lists of say a hundred stars or so, which, as soon as he had obtained some five observations, he struck off and never reobserved again. This, of course, largely increases the difficulty of making the reduction of the transits homogeneous in character. It would appear that Groombridge, when he first set up his instrument, observed transits of all stars over all the wires, the well-known polars, plenty of clock stars, and what we now call fundamental stars, and evidently satisfied himself of the general excellency of the state of his instrument and clock. After assuring himself on these points, it would appear that he mainly relied on keeping his instrument in the meridian by frequent adjustments, as to the nature and time of which there are no records whatever. With regard to the transits, we find that during the years 1806 and 1807, the majority of the transits were over all the wires; for 1808 to the middle of 1809 the transits were symmetrical, either over all wires, middle three, or the centre only ; from the middle of 1809 to the middle of 1811 either over the centre wire only or two unsymmetrical wires, generally wires 2 and 3, or 3 and 4 ; from the middle- of 1811 to the end of 1812, either over the centre wire only, or two wires, generally 1 and 2 ; and for the rest of the period generally two of the outside wires or the centre only. The clock stars throughout were nearly always observed on all the wires. Thus it will be seen that the large number of broken transits makes the accurate determination of the wire intervals important. The reduction of the North VI INTRODUCTION TO GROOMBRIDGE CATALOG-UE. Polar distances is homogeneous throughout, for it was evidently Groombridge's plan to make them differential, and for this purpose he adopted a list of stars, nearly all of which are included in modern fundamental catalogues, and some of which were always observed in the course of each night's observations. ^ The material which forms the basis of the Catalogue is contained in two books headed The Transit Book and The Zenith Distance Book respectively. In The Transit Book are entered the original times of the clock corresponding to the different wires, and these clock times are the starting point from which the new transit reductions have set out. In The Zenith Distance Book the separate readings of the four microscopes as entered by Groombridge (but which are not the original readings of the microscope micrometer heads as read by him and entered on his slates, and of which there are no records) constitute the starting point of the North Polar distances. There are no records whatever as to observations of a mark, as to the errors of collimation, level, or azimuth, or as to the times when the instrument was adjusted, or as to the occasions when a transit wire was broken. On one occasion only a note referring to the state of the instrument reads as follows: 1808, Nov. 30. "Having struck and moved the axis in azimuth l" - 341, the correction of the error in E. A. is calculated for each star." The following dates of the reversal of the instrument appear sometimes in both the books called The Transit Book and The Zenith Distance Book, sometimes in one or the other, and from the evidence of the wire intervals seem to be complete. The conven- tion adopted is "East" for the illuminator to the east, and " West" for the illuminator to the west of the instrument. 1806 June 1 1 East June 27 West July 14 East September 29 West 1807 January 12 East February 23 West May 1 1 East Juue z West 1807 September 19 East 1808 May 4 West 1809 February 22 East November 27 West 1810 November 23 East 1812 May 13 West 1813 May 8 East Between 1813, May 8, and the last date of observation for the Catalogue the position of the instrument remained unchanged. The dates given above for the change of the position of the instrument correspond to the first date when there were any observa- tions after the reversal. For the reduction of the observations the positions of the clock stars, standard polars and stars used for polar points have been derived from Professor Newcomb's OBSERVATIONS, vii Catalogue of Fundamental Stars for the epochs 1875 and 1900. In the ledgers and catalogue from Groombriclge's observations, owing to the short extent and small number of the groups, the Right Ascensions of the clock stars have not been kept for place. The place of Polaris depends on consecutive double transits only, and the places of the other standard polars depend on the ob3ervations only of those nights on which Groombridge made observations of Polaris or Polaris S.P. on the same day, and when necessary the error so derived is specially applied. As the observations of the standard polars were insufficient to give azimuth errors for every day's observations, supplementary lists of stars, whose places depend on observations on days on which some of the standard polars were also observed, were drawn up, and these stars, where necessary, have been used for the determination of azimuth error. . In this way, as far as possible, the Right Ascensions were made fundamental for as long as possible. As the number of observa- tions of the standard polars fell off, and it became more and more difficult to get material to determine the azimuth error, any Newcomb star that happened to be observed on any night was taken for the purpose, and the place derived from Newcomb's Catalogue used. Then generally as the material got more and more scanty extended lists of stars were made ; stars which had been observed on previous nights, and for which some sort of place could be obtained had to be used, but no observation of a star was kept for place in the Catalogue if it had been in any way used for determination of the night's errors, unless it was one of three or more. The attempt to make the Groombridge Right Ascensions practically fundamental could not be sustained for long, but a comparison 1 xt ween the adopted places which are given below as derived from Groombridge's observations (for the year 1807 principally) and which were used for azimuth .error, and the Newcomb Catalogue derived place, shows that no systematic error can have been introduced into the reductions by this premature effort to make the observations as fundamental as possible. The North Polar distances are strictly differential, and the polar points are derived from all Newcomb f-tars observed on any night. It was at first considered that a polar point depending on six Newcomb stars would give good results, but a comparison of the first three years' resulting places of the Newcomb stars with the places derived from Newcomb's Catalogue showed discordances varying with the N.P.D. and the position of the instrument. Accordingly a recomputation of the polar points was made for all days on which ten or more Newcomb stars were observed, and which stars extended over an arc of at least 30, and these observations of the Newcomb stars observed on such days were ledgered, and a fresh comparison made with the places derived from Newcomb's Catalogue. The comparison arranged for every degree of N.P.D. was of such a character as to leave no doubt of the necessity of the application of a correction of the nature of a division error. The internal evidence derived from the agreement viii INTRODUCTION TO GROOMBRIDGE CATALOGUE. of the two faces East and West, as also from the large error indicated for the arc 15- 18 Face West, afforded additional proof that the error could not be due to Newcomb's Catalogue places. The following stars in Newcomb's Catalogue were not used for polar points Newcomb, NOB. 424, 578, 886, and 1464, corresponding to Groombridge, Nos. 1159, 1513, 2078, and 3716. The following numbers, which were originally in the Groombridge Catalogue, are now left blank, as there are no stars in the positions originally given Groombridge 805, 812, 2144, 2661, 2795, 2940, 3647, 3932, and 4018. The following additions have been made to the original Catalogue Groombridge 2661a, 26616, 3192a, 3320a and 4l7la. The observations having been made with a reversible instrument, the two faces are kept separate in the ledgers. The revision of an old catalogue must always be a source of anxiety to those responsible for the revision, and is, in fact, only to be justified by the final results. As to the value of this series of observations, made at a time when observations are scarce, with an excellent instrument, and with laborious care, there can, it would seem, be no question. The only question was whether the data which would be found would supply sufficient material to carry out the revision, and give results in accordance with modern ideas of accuracy. The revision has been complete, for the computations have been made de novo, and the material available for instrumental adjustments, though not by any means all that could be wished for, and which at times has caused serious anxiety, has, it may be fairly claimed, afforded a substantial basis for the determination of the proper motions of some 3000 to 4000 stars, as additional material for the discussion of the value of the constants of precession and of the position of the apex of the solar motion. IV. RIGHT ASCENSIONS. The Right Ascensions are deduced from the clock times as given by Groombridge in The Book of Transits, reduced to the centre wire corrected for n tan S, clock error and clock rate, and star correction. Wire. Intervals. As has been mentioned before, Groombridge mostly observed broken transits, and consequently the wire intervals are of considerable importance. These have been RIGHT ASCENSIONS. IX carefully rediscussed from the original clock times and were adopted from time to time during the progress of the work. The material for the computation after the first year or so is mainly confined to clock stars, and as there are no records of broken webs, the difficulty of distinguishing between what may be considered as legitimate differences of observations and a really new wire are considerable. The following values for reduction to centre wire were adopted for Face East : Years. Wire I. Wire II. Wire III. Wire IV. Wire V.

The chief difficulty felt in reducing the transits has been the absence of sufficient material' for deducing a correction of the form n tan $ + c sec , There are a few S.P. observations, and on occasion some high and low stars, but the material was so scanty that no reliable information could be obtained. On nights when there were a good many stars for which reliable places could be obtained comparisons were made between the tabular and observed places, and the results treated by least squares, but the deduced corrections were of such a character, and the material so faulty that it was apparent that no useful or reliable correction could be got. From a general consideration, however, of the small limits of N.P.D. within which Groombridge usually chose his stars for a night's observa- tions, the residual collimation error would to a large extent be compensated by the adopted values of n and clock error. To make the mean N.P.D. of the stars used for clock error accord more nearly with the general body of the stars observed, all stars between 35-52 N.P.D. for which reliable places could be found were used as adjuncts to the clock error, with the same weight as though they were the regular clock stars. The value of " n" has been derived in the ordinary way: (1) from the regular polars wherever possible ; (2) from other Newcomb stars ; and (3) from Groombridge stars, the places of which had been observed on nights on which reliable values of "n" were obtained. The tabular places, except during the year 1807, when, as mentioned above, p. vii., effort was made to make the Right Ascensions fundamental, were in all cases, whenever possible, derived from Newcomb's Fundamental Catalogue. The re- duction to apparent place was made from Tabula Quantitatum Bessilianarum pro annis 1750 ad 1840 Computatse. Otto Struve, Petropoli, 18G9. As long and as much aa possible the value of " n " derived from each day's observations has been kept separate, and used for that day's obervatious, simply because there are no records of when or how the instrument was adjusted, but as the material for " n " became less and less it became necessary to combine groups of " n" over longer intervals. HICHT ASCENSIONS. The data on which the values of " n " depend are given in the following tables. The first table gives for each year the adopted place for the year of all the stars used for "n," the approximate N.P.D., and the value of tan $, and the second table gives the observed and adopted " n " for each day's observations. The column headed " authority " signifies whether the place is derived from Newcomb's Catalogue (N) or from Groombridge's observations, in which latter case the number refers to the number of observations on which the adopted place depends.

XXXV Clock Error. The clock error cannot be described as well determined by Groombridge. He adopted thirty-six standard stars, six of which constituted a good night's determination, but more often than not there were only two or three, and as some of these stars, as Sinus, Spica, a Librae, Autares, a Capricorni, and Fomalhaut were of very different N.I'.D. to that of the Catalogue stars, the effect of any error of collimation might appreciably affect the Right Ascensions. Generally speaking, the range of the clock errors deduced from separate stars was considerably larger than what would be shown by present observations. The clock errors have been deduced from a comparison of the observed transits corrected to the centre wire and for n tan $ with apparent places derived from Newcomb's Fundamental Catalogue. From a careful discussion of the results of each night's observations when reliable material was available, it was evident that an improvement in the observed places would be effected by extending the stars used for clock error so as to make them as nearly as possible of the same N.P.D. as the Catalogue stars. Accordingly, stars of N.P.D. 30 to 52 for which reliable places could be obtained, that is practically Newcomb and Bradley stars, were taken on every night on which they were observed, and the following corrections to the adopted clock errors were obtained by giving equal weights to every star, whether an original clock star or a new one. The material for such a correction extends practically only to the summer of 1810. After this date the comparison of the separate days in the ledgers indicated a few days with systematic discordances from the mean, and the corrections are given which were adopted for ten such days from 1810, Oct. 8. For this purpose the Right Ascensions of the Bradley stars for 1810 were taken from Kobold's paper, " Untersuchung der Eigenbewegungen des Auwers-Bradley-Catalogs," corrected by 8 '04 for equinox.

All star corrections have been recomputed from Tabulse Quantitatum Besselianarum pro annis 1750 ad 1840 Computatse Otto Struve, Petropoli, 1869. For all stars used for instrumental purposes proper motions have been used. These stars are marked with an asterisk * in the ledgers, and a list of the proper motions so used will be found under the section Ledger, pp. xlii.-xliv. V. NOETH POLAR DISTANCES. The North Polar Distances are deduced from the microscope-micrometer readings as given by Groombridge in The Book of Zenith Distances by taking the simple mean and adding corrections for refaction, polar point, and star corrections. The material for the polar points is uniform throughout, and though it is much more abundant up to the middle of 1810 than for the remaining period, it may be considered as sufficient throughout, a fact which makes the North Polar Distances homogeneous. The chief difficulty felt in dealing with them has been as to what to do with discordant results. Owing to the fact that the figures set down for the individual microscope readings could not have been always the original readings of the micrometer heads, and that Groombridge was known to have manipulated the original readings by certain calculations which are not known, it was considered best to bracket discordant observa- tions rather than make what appeared to be probable corrections. The computations have been carried to two places of decimals. Refraction. The refractions have been computed from the Pulkowa Tables for the readings of the barometer and thermometer given by Groombridge, the readings of the exterior thermometer when available being always used. As these readings were not very frequent, interpolations when advisable were made. Polar Points. These were obtained by comparing the observed zenith distances corrected for refraction and division error with the places derived from Newcomb's Fundamental Catalogue reduced to apparent place with star corrections deduced from Struve's tables referred to above. The observations of these fundamental stars were not kept for place, unless there were at least four. Division Errors. As most of the Newcomb stars were observed by Groombridge between the years 1806-1810, a comparison of the resulting N.P.D.'s from this period was made, the result of which was to show that there were considerable systematic errors, which ranged them- selves in order when grouped according to N.P.D. and the position of the instrument. NORTH POLAR DISTANCES. xxxix The original computation had been made on the assumption that six Newcomb stars would give a good result for the polar point, but in view of these systematic differences a recomputation of the polar points was made on all days on which there were at least ten Newcomb stars extending over an arc of 30 of N.P.D. Corresponding corrections having been applied for these new polar points, a fresh comparison was made with Newcomb's adopted places, and these new differences grouped according to the position of the instrument for every degree of N.P.D. As the instrument was reversible and there were two circles, the two positions of the instrument gave independent corrections for the same distances from the zenith, that i.-, covering the arc 25 to 51 of N.P.D. From the pole to 25 for the first ten degrees there was not sufficient material to give any reliable corrections, and from 11 to 25 the corrections could only be obtained from one position. Preliminary corrections thus obtained were then applied to all stars used for polar points, and the polar points were ba^cd on the use of all Newcomb stars observed on each night. The final values of the following division errors depend on the use of all Newcomb stars on all nights, and do not materially differ from the preliminary values. The following tables show the correc- ti nis for division error, and the residual errors for face east and west. The quantities for the correction to any degree depend on stars whose N.P.D. falls strictly within that degree, and the corrections have been so applied ; for instance, the correction for 38 is the correction for all stars between 38 and 39. It should also be remembered that the correction for the two circles at the same distance from the zenith in opposite directions is the same with the sign reversed ; for instance, 39 East is the same as 37 West, and so on. The detailed comparison from each star will be found in the section Comparison of Catalogues (pp. IL-lix. I. Table of Corrections fur Division Error. N.P.D. Bmt ffMt, x.r.D. East. Wet. N.P.D. East.

The Right Ascensions and North Polar Distances, with the days of observation, entered in this section are derived from the daily results reduced by the methods described above. As the instrument was a reversible one, each face is given separately with a corresponding mean. The observations are all reduced to the epoch 1810'Q with the precessions and secular variations embodied in the Catalogue. In this section the great majority of the stars are reduced without proper motion. Those stars LEDGERS. xli marked with an asterisk * were reduced with the proper motions given in the list pp. xlii.-xliv. No correction for division error has been applied to the results in this section. As a general rule no hypothetical corrections have been applied to discordant rvutions, but observations which stand out from the mean 4" either in R.A. or N.I'.D. have generally been bracketed. The number bracketed in R.A is 75, that in N. P.D. is 214, slightly over one per cent, of the total number of observations. No observations of R.A. made below pole except those of Polaris have been em- bodied in the Catalogue places, though printed in the ledgers. They are, however, few in number. Observations of N.P.D. made below pole have been used in forming the Catalogue place of stars within 10 of the pole. Beyond 10 the observations below pole have not been used for the Catalogue place. The stars in this section are named according to the original numbering of Groombridge. Blanks are left where the original number now has no corresponding star position, and additional stars are inserted in their proper order with a small Roman letter added to the number of the preceding star. The following Nos. are blank 805, 812, 2144, 2661, 2795, 2940, 3647, 3932, 4018. The following are additional stars 2661a, 26616, 3192a, 3320a, 4171. The star called 331 la in the ledgers is restored in the Catalogue section to its original No., 3297. The mean places of the following stars are considered discordant, and have not been used in the section of proper motions. In R.A. In N.P.D. In N.P.D.

CATALOGUE. The Right Ascensions and North Polar Distances for 1810'0 have been reduced as described above. The clock stars, standard polars, and the places of stars used for polar points have been derived from Professor Newcomb's Fundamental Catalogue, and the computation of refraction has been made by the use of the Pulkowa Tables. The results here given are derived from the ledgers by combining the different faces with weights equal to the number of observations. Corrections have been applied where necessary to reduce the observations to 1810D, for the values of proper motions specially deduced in the following section, and further in the case of the North Polar Distances for the corrections for division error given on p. xxxix. No observations of RA. below pole (except in the case of Polaris) have been used in the Catalogue place. In N.P.D. observations below pole for stars within ] of the pole have been used with full weight. CATALOGUE. xlv Explanation of the Separate Columns. The reference No. is that given in the original catalogue. Where, for reasons in the footnotes, there is no corresponding star position, the No. is left blank. Additional stars are inserted in their proper order of R.A. with the reference No. of the previous star, followed by a small suffix Roman letter. The No. in Auwer's Bradley sufficiently explains itself. The No. in Greenwich Catalogues gives the reference to the Catalogue from which the star's place has been taken for comparison with the Groombridge result, and which has been used in the following section of deduced proper motions. The No. without an asterisk refers to the second Ten Year Catalogue for 1890. The No. with an asterisk * refers to the First Ten Year Catalogue for 1880. The No. with a dagger t refers to the Nine Year Catalogue for 1872. In cases where the Greenwich place has been taken from observations since 1897, a footnote gives the year or years in which the observations used for the place were made. The star's name follows the rules of nomenclature usually adopted at Greenwich. The magnitudes arc taken from the following sources in the order given. The Harvard Photometric Durchmusterung (Annals of Harvard College, vol. xlv.), the Catalogues of the Astronomische Gesellschaft (marked *) or the Bonn Durchmusterung (marked t). Type of Spectrum is taken from the Draper Catalogue of Stellar Spectra (Annals of the Astronomical Observatory of Harvard College, vol. xxvii.). The character of the spectra of the different stars is there indicated by the letters of the alphabet. The varieties of Type I. are indicated by the letters A to D ; those of Type II. by the letters E to L (pp. 2-4, Introduction). No reference is given except to stars of Types I. and II. The mean date is expressed in years and decimals of a year reckoned from 1800, corresponding to the days of observation. The number of observations gives the aggregate number of all the observations in the different years upon which the star's place depends. The precessions and secular variations for ISIO'O have been computed from the Struve Peters' constants of precession by the use of Folie's Tables Douze Tables pour le calcul des Reductions Stellaires. The R.A. and N.P.D. have been taken for ISIO'O correct to I 8 and 2" respectively. xlvi INTRODUCTION TO GROOMRRIDGE CATALOGUE. The annual proper motion which is the value derived from the discussion of the Groombridge observations, details of which are given in the following section, has been used in this section to reduce all observations to the epoch 181 0'O. VIII. PROPEE MOTIONS. The proper motions given here are derived in the main from a direct comparison of the results of the new reduction of Groombridge's observations with those of recent Greenwich Catalogues and are deduced for the epoch 1850. They arc embodied in the Catalogue without any corrections for secular variation. The proper motions marked with an asterisk * are those which are not derived solely from a comparison between the Groombridge and Greenwich results. The great majority of these are cases where the Groombridge results depend on only one or two observations. Where discordances were considerable, and seemed to be fairly divided between Groombridge and Radcliffe, the resulting proper motions derived by comparing Greenwich and Groombridge and Greenwich and Radcliffe, were combined according to the relative number of their observations, after giving double weight to those of Groombridge. In a few cases the adopted proper motion has been derived solely from the result of the comparison between Radcliffe and Greenwich. The object of comparing the results of the Groombridge, Radcliffe, Astronotnische Gesellschaft, and Greenwich Catalogues side by side was that while the Radcliffe and Astronomische Gesellschaft Catalogues would be a useful check on the proper motions derived from the Groombridge and Greenwich results, the residuals derived from the comparisons would afford valuable material for a discussion of the systematic errors of the Radcliffe and Astronomische Gesellschaft Catalogues. The Greenwich Right Ascensions and North Polar Distances for 1890'0 are mainly derived from the Second Ten Year Catalogue for 1890'0. Of the 605 Groombridge stars not to be found in this Catalogue, the places of 104 are derived from the Nine Year Catalogue for 1872, of 408 from the First Ten Year Catalogue for 1880, and of 93 from the results of observations made since 1896. Numbers representing blanks, additional stars, or discordant results will be found on p. xli. Reduction to 1890U The Groombridge Right Ascensions and North Polar Distances given in this section for 1890'0 are the same places as those given in the section "Catalogue," but without PROPER MOTIONS. xlvii any correction for proper motion. The reduction from 1810'G to 1890'0 was made by means of the Struve Peters' constants of precession from Folie's Tables. For stars Ix'yond 5 from the pole the reduction has been effected by taking the mean of the pre- cessions for 1810'G and 1890'0 and by applying the additional correction for the third term where necessary. For stars within 5 of the pole the reduction has been made by the following formula : R.A. l8lo + 80 x />,s 50 + 18-67 (jj, 8lo + p l890 - 2 j>,8 5 o) + 1-07 (sec. var n -, 8lo - sec. var n - l890 ). The Radcliffe Right Ascensions and North Polar Distances for 1890'0 are the places deduced from the Radcliffe Catalogue, 1845, without any correction for proper motion. The reduction from 1845 to 1890 was made by means of the Struve Peters' constants of precession from Folie's Tables. For stars beyond 5 from the pole the reduction has been effected by taking the mean of the Struve Peters' precession for 1845 and 1890 and by applying the additional correction for the third term if necessary. For stars within 5 of the pole the reduction has been made by the following formula : (R.A.,s 4S + 5 />, 350 | sec. var n -, 850 ) + (total procession from 1810 to 1890) + 10 (/>, 890 Pis, ) '-. (sec. var n - l890 + sec. var n -, 8lo 2 sec. var n -, 8so ). The Right Ascensions and North Polar Distances have been further corrected for .systematic errors which are given below. The Right Ascensions and North Polar Distances for 1890'0 of the various Astronomische Gesellschaft Catalogues are the places deduced directly from the Catalogue for 1875. The reductions from 1875 to 1890 are made by taking the means of the precessions at the two epochs. Those stars which are marked as fundamental in these catalogues have not been used in this comparison. The reductions to 1890'0 for the Greenwich Catalogues arc made by taking the mean of the precessions at the two epochs. No corrections have been applied for proper motion. Systematic Corrections. As the new reduction of Groombridge's observations is based on the system of Professor Newcouib's Fundamental Catalogue for 1900, and as the main difference between this Catalogue and the modern Greenwich Catalogues (Introduction to Greenwich Ten Year Catalogue, 1890, pp. 44-46) consists, in the case of the Right Ascensions, of different epoch corrections, and in the case of the North Polar Distances of the use of different xlviii INTRODUCTION TO GROOMBRIDGE CATALOGUE. refraction tables, all the Greenwich Right Ascensions referred to 1890'0 have been corrected as follows : Nine Year Catalogue, 1 872 First Ten Year Catalogue, 1880 Second Ten Year Catalogue, 1890 ) Stars observed since 1896 . J + 0-03 + 0-04 +0-05 and the use of Pulkowa Refraction Tables has been substituted for those of Bessel in the reduction of the North Polar Distances by means of the following table. In applying these corrections it must be borne in mind that for observations below pole full weight is given as far as N.P.D. 15 ; from 15 to 36, f weight ; from 36 to 41, 5- weight ; and below 41 the observations below pole are not used. The North Polar Distances of the 1872 Catalogue have been specially corrected by the use of the table published on p. 27 of the introduction to that catalogue.

In the following comparisons the Struve Peters' value of precession, and the proper motions deduced in this work, have been used. The Groombridge Catalogue places, as has been explained above, depend on Newcomb's Fundamental Catalogue, and the modern Greenwich places, as has also been explained above, have been INTRODUCTION TO GROOMBHIDGE CATALOGUE. brought into line with Newcomb's Catalogue (see Introduction, Greenwich Ten Year Catalogue, 1890, pp. 44-46) by applying an epoch correction to the .Right Ascensions, and by reducing the North Polar Distances with Pulkowa refractions from the table given on p. xlviii. Consequently, the comparisons are made with an adopted Groombridge-Greenwich system of R.A. and N.P.D., depending at one end on the Groombridge Catalogue for 1810'0, and at the other in the main on the Greenwich Ten Year Catalogue for 1890. Comparisons are made with the following Catalogues : 1. Professor Newcomb's Fundamental Catalogue for 1875 and 1900. 2 Professor A.uwer's Bradley Catalogue from the places given by Dr. Herman Kobold for 1810 in his paper Untersuchung der Eigenbewegungen des Auwers- Bradley Catalogs nach der Bessel'schen Methode. 3. Professor Struve's Catologus generalis continens positioned medias ad 1830'0 reductas ex observationibus meridianis annis 1822 ad 1843 in specula Dorpatensi institutis. 4.

The places of Newcomb's Catalogue were reduced to 1810'G by means of the formulae given in his Catalogue, and of the values of the precessions and proper motion adopted by him. The separate results of Groombridge's observations for face East and West are those given in the section "Ledgers," reduced to 1810'G with the proper motions used in the Ledgers, pp. xlii.-xliv., and not with those given in the final Catalogue. The resulting differences in N.P.D. constitute the basis of the division errors given on p. xxxix. For combining the resulting differences for the two faces, the following weights were used : No. of Observations. 1 2-4 5-9 10 and over Wi-ight.

This comparison having been made at a later date of the reductions than that with Newcomb's Catalogue, the Groombridge Eight Ascensions and North Polar Distances given in the Ledgers for faces East and West have been corrected for the proper motions given in the Catalogue section, and in the case of the North Polar Distances for division error. As these latter results are not immediately available for comparison, the results themselves are given in the following table. The comparison with Bradley is effected by using the places of the Auwer's Bradley stars reduced to 1810'Q by Dr. Kobold in his paper for the determination of the solar motion, entitled Untersuchung der Eigenbewegungen des Auwers- Bradley Catalogs nach der Bessel'schen Methode. The quantities East-Bradley and West-Bradley are the differences found by comparing the Groombridge results for faces East and West with the corresponding R.A. and N.P.D given by Kobold in the column headed 1810'G. In the course of the computations the following errata, obtained by recomputing the data, were found from the anomalous results given by the printed result. Errata used in Dr. Kobold's Paper.

Attention may again be called to the agreement in Right Ascension between the two faces East and West. COMPARISON OP CATALOGUES. Ixiii Comparison between Groombridge and Bradley. N.P.D.

The following tables are derived from the results given in the section of proper motions under the heading Residuals C 0. The residuals have been cleared of the systematic corrections, p. xlviii-xlix, applied to the original catalogue places, and there- fore represent the systematic corrections to the Radcliffe Catalogue from a direct com- parison between Groombridge and the Greenwich modern catalogues referred to the equinox of Newcomb's Catalogue in R.A. and reduced with Pulkowa refractions in N.P.D.

Ixxxv Comparison ivith the Astronomische Gesellschaft Catalogues, The following Catalogues of this series have been used : Catalogue. Limits of N.P.D. Kasan Christiania . HelsingfoH Harvard Bonn 10 to 15 1869-1892 20 ,, 25 1870-1881 25 35 1869-1880 35 40 1870-1884 40 50 1869-1891 T , < 1870-1882 Lund 5 55 { ,892-1895 The results of the present comparison are derived from the section Proper Motions, under the heading Residuals C 0, and as no systematic corrections were applied to the original catalogue places, they, therefore, represent the systematic corrections to each catalogue of the series, from a direct comparison with Greenwich modern catalogues referred to the equinox of Newcomb's Catalogue in R.A., and reduced with Pulkowa refractions in N.P.D. by the use of the Groombridge proper motions for the average interval of about twelve years. A previous comparison of the first five of these catalogues with the Greenwich Ten Year Catalogue for 1890 was published on p. 47 of the introduction to that catalogue. Correcting the quantities there given, in R.A. to the equinox of Newcomb's Catalogue, and in N.P.D. to Pulkowa refractions, the two sets of comparisons are made comparable. The Lund Catalogue has been published since the Greenwich Ten Year Catalogue of 1890 was completed. Part of the differences between the two sets of comparison may be due to the reason that in this new comparison the stars marked as fundamental in the various Astronomische Gesellschaft catalogues have not been used and that some additional Groombridge stars which were not observed in the Ten Year Catalogue for 1890 have been included ; the chief cause, however, for the difference between the two results is that all the stars in tlus new comparison have been reduced from the epoch of observation to 1890 with proper motions, whereas in the previous comparison given in the introduction to the Ten Year Catalogue, 1890, there were only a limited number of stars, mostly those with large proper motions, for which proper motions were determined. The importance of the general result of this discussion on the amount of the systematic errors which may be introduced into star places through unknown proper motions is sufficient excuse for the following details. rxxxvi INTRODUCTION TO GROOMBRIDGE CATALOGUE. In the following tables are given for each hour of Right Ascension the results of these two comparisons, the differences between them called R and R' (columns 4 and 7 respectively), and the number of stars in each comparison. In the case of the Lund Catalogue the results of the new comparison only are given, as it has been published since the Ten Year Catalogue, 1890, was printed. Now, taking the values of R and R' as given in columns 4 and 7 for each 3 h of R.A., and assuming that A sin a + B cos a + C = E A' sin a + B' cos a + C' = R' the following values are found : Catalogue.

If we assume that the observations of these five catalogues are fairly distributed over the periods during which the observations extended, then the following table roughly represents the mean date and the number of years for which solar motion was required.

DISCUSSION OF PROPER MOTIONS. The Groombridge proper motions are in some ways very suitable for a determina- tion of the constant of precession and of the solar motion. The stars are of mean magnitude 7 m% 0, and therefore such as might well have been observed without any large errors depending on magnitude, and on the other hand they do not consist of too exclusively bright stars. The constant of precession and direction of the solar motion have been obtained from frequent discussions of the proper motions of Auwers' Bradley DISCUSSION OF PROPER MOTIONS. xci and a determination made from the proper motions of the stars used by Groombridge is largely fresh material, which, however, is confined to a very limited region of the sky. As the question of want of uniformity in the distribution of the stars themselves or of their proper motions directly affects the question of precession and solar motion, the following analysis has first been made. Distribution of the Stars according to (i.) Magnitude, (ii.) Magnitude of Proper Motion, and (iii.) Type of Spectrum. (i.) Distribution of Stars according to Magnitude. The stars observed in Groombridge's Catalogue lie within 52 of the North Pole, and are, generally speaking, the brighter stars in this part of the sky ; it is only very occasionally that a star as faint as 9 m- is observed. The mean magnitude is exactly 7 m '0. The magnitudes are taken from the Harvard Durchmusterung where possible, and in other cases from the catalogues of the Astronomische Gesellschaft or the Bonn Durchmusterung. The following table is an analysis of the stars' magnitudes in each octant of right ascension : Limits of R.A.

This peculiarity in the distribution of the stars is in no way attributable to Groombridge's habits of observing, but is entirely due to the actual differences of star-density in different parts of the area covered by the catalogue. Comparison with Seeliger's counts of the total number of stars of different magnitudes shows that XC11 INTRODUCTION TO GROOMBRIDGE CATALOGUE. Groombridge observed the same percentage of stars of the same magnitude throughout the 24 h of Eight Ascension. In the portion of the sky observed by him his catalogue contains : 70 per cent, of the stars from i-o to 6-5. 35 6 ' 6 .. 7'0. '5 ,, 7' ,, 7'9- and 3 ,, , s ,, 8 '9- The large differences in the number of stars in different parts of the sky, suggesting the probability of systematic differences in the mean distances of groups of stars in different parts of the sky, make it desirable in some cases to make two solutions for the direction of the solar motion, one giving equal weights to equal areas of the sky, and the other to each star. As will be seen in the section headed Solar Motion, when the weight is according to area the position of the solar apex is some degrees further south than when the weight is according to the number of stars. (ii.) Distribution of Stars according to Magnitude of Proper Motion. The stars were divided into groups according as the total proper motion per century fell between the limits 0" to 5", 5" to 10", 10" to 20", or was greater than 20". The following table gives the numbers and percentage of stars belonging to these groups for different magnitudes : Number of Stars. Percentage of Stars. Centennial Proper Motion.

Nearly 60 per cent, of the bright stars have a proper motion of less than 5" a century, and more than 25 per cent, of the faint stars have a proper motion of more than 5" a century. (iii.) The tables of percentages show the large relative preponderance of stars of large proper motion about 12 h of right ascension. Taking the proper motions as a gauge of the distances of the stars, there is here shown a want of symmetry in the * It will be noticed that these numbers do not exactly tally with those given above. A few stars have probably been omitted accidentally in the second table. XC1V INTRODUCTION TO GROOMBRIDGE CATALOGUE. distribution of the stars which may well affect the determination of the position of the solar apex. (iii.) Distribution of the Stars and their Profer Motions according to Type of Spectra. It has been shown by Kapteyn, from a discussion of the proper motions of the Bradley stars, that in general stars of Type II. have larger proper motions than those of Type I. It will be seen that this result is borne out by the following analysis of the stars common to the Groombridge and the Draper Catalogue (Harvard Annals, vol. xxvii.) under the headings of Type I. (classified by Professor Pickering as A, B, C, or D) and of Type II. (classified by the letters E to L).

The stars of Type II. are distributed with extreme regularity in the different octants. On the other hand, the stars of Type I. have a ver} r marked condensation between 18 h and G h where the Milky Way passes through the observed area, and this is especially the case with the stars of smallest proper motion (0"-5") Since the above tables were prepared, vol. IvL, No. 1 of the Annals of the Harvard College Observatory has been received, in which Professor Pickering gives an analysis of the distribution of the stars of different types in the whole of the Draper Catalogue, and concludes as follows : " The Universe is thus shown to consist of two portions, first, the stars of the first type, which though frequent in all parts of the sky, pre- dominate along a certain plane, thus forming the Milky Way. . . . The stars of the second and third types show no concentration in the Milky Way, but are, in general, uniformly distributed in all parts of the sky. These two portions should be treated separately in all discussion of the structure of the Universe, such as studies of proper motion, parallax, motion of the Sun in space, etc." The tables given above entirely confirm Professor Pickering's statements, and extend them in that they show that the uniformity of distribution of stars of Type II. holds good when they are subdivided according to the magnitude of their proper motions. The relatively large proper motion of stars of Type II. has been pointed out by Kapteyn from a discussion largely of Bradley proper motions ; and this peculiarity is borne out by the following comparison of the present results with those given by Kapteyn. A number of the stars, enpecially those of large proper motion, are common to the two lists; but as only 16 per cent, of the Groombridge stars are also Bradley stars, the two lists are essentially independent.

Their distribution XCV1 INTRODUCTION TO GROOMBHIDGE CATALOGUE. in space appears to be the same in all directions from the Sun, their proper motions to show that their mean distance from the Sun and distribution with respect to this mean is the same in all directions, and, further, their distances to be such that the effect of parallactic motion is considerable. The stars of Type I. on the other hand appear to be condensed near the Milky Way, and this is especially the case with the stars of small proper motion. It would thus seem that the mean distances of these stars are different in different directions, and the determination of the solar motion from them to be a matter of increased difficulty. XI. DETERMINATION OF PEECESSIONAL CONSTANT. The Precessional Constant m. In this section the mean proper motions are given for each three hours of right ascension, and the material is arranged for discussion of (a) the magnitude equation of Groombridge as compared with the modern Greenwich observers, (b) a determination of the processional constant m. The advantages of an arrangement in groups of three hours are that the data are compressed into small compass, and their general character is more readily perceived than in more extended tables. (a) Mean Proper Motions of Stars of Different Magnitudes for each Octant. The proper motions in right ascension having been first converted into arc of a great circle, the means were taken for all the stars between the limits 15-52 of N.P.D. for each three hours of right ascension. No stars were omitted, and the results are shown in the following table : Mean Centennial Proper Motions of all Stars between the Limits, 15-52N.P.D. RiKht Ascension. North Polar Distance.

Taking the results of the latter table as being more free from accidentally large proper motions, the means in R.A. are as follows : Mags. 1-0-4-9 5-0-5-9 6-0-6-9 7-0-7-9 8-0-8-9 -0-31 -0-65 -0-41 -0-29 -0-55 No. of Stars. 200 454 1003 1239 811 The effect of solar motion in Right Ascension being eliminated by taking simple means, the general agreement of the results for all magnitudes shows that Groombridge's magnitude equation was substantially the same as that of the modern Greenwich observers. While the resulting quantities in R.A. may arise from systematic errors, erroneous pre- cession, or an accumulation of large proper motions about 12 h , those in N.P.D. are mainly to be attributed to the solar motion. Detailed consideration of these points follows. (b) The Precessional Constant m.

The question arises whether it is due to systematic error in the Groom- bridge Catalogue at this N.P.D. or whether it may be attributed to those inequalities in the distribution of the stars and their proper motions to which attention was drawn in the last section. At O h this zone is very near the Milky Way, and at 12 h a long way from it, and an analysis of the mean proper motions in this zone from stars whose total proper motions lie between certain limits shows the following differences : Analysis of Mean Proper Motions for Zone 45 52.

Thus, between 21 h and 3 h , where the solar motion gives positive motion in right ascension, the numbers of stars are in the ratio 77 : 16 : 7, while between 9 h and 15 h , where the solar motion gives negative motion in right ascension, these numbers are in the ratio 48 : 23 : 20. DETERMINATION OF PRECESSIONAL CONSTANT. XC.1X The large negative proper motions at 12 h thus have a very considerable effect on the mean, and tables corresponding to the one on p. xcviii. have been formed for the other zones in which the stars chosen are limited to those with proper motions of less than 10" a century and 5" a century respectively. The former appears to be a sufficiently ample limit, but the latter is probably too small.

It would seem that the differences in the mean values for the different zones shown in the table on p. xcviii may be partly ascribed to the inequalities in the distribution of stars with large proper motions, and therefore the adopted values given in the last line have been taken as the resulting mean proper motions for these zones. These adopted values, when corrected for the systematic errors of Groombridge's Catalogue, form corrections Am cos $ o to the adopted centennial value of the precessional constant m, $ o being the mean declination for each group. The following table gives the corrections to reduce Groombridge's Catalogue to the systems of Newcomb, Auwers, and Boss. The comparison with Newcomb has been made directty, that with Auwers is derived from his recently published tables* (the results of the new reduction having been sent to him in advance), and that with Boss by applying the corrections Boss-Newcomb for 1810, derived from Ast.

DETERMINATION OF PRECESSIONAL CONSTANT. ci The solution of the above equations gives Am = +"'13 as the centennial correction to the Struve- Peters' value of m, or +"'65 to Newcomb's value. If the right ascensions of Groombridge had been reduced to Auwers's system by the corrections given by him, the deduced value of m would have been about 0"'2 per century larger, and reduced to Boss's system about 0"'4 smaller. The Precessional Constant n. To determine the value of the precession, we should, if we could pick them out, use stars so distant that they are unaffected by the solar motion. Let X, Y, Z be the centennial displacement of the Sun relative to any class of stars, and let An be the correction required by the precessional constant n. Then m will require a correction, An cot e, where e is the obliquity of the ecliptic, and each star will give rise to two equations : X sin a Y cos a + An (cot < cos 8 + sin a sin 8) = yu, i (i.) and X cos a sin 8 + Y sin a sin 8 Z cos 5 + An cos a = // J (ii.) If the stars were so distant that the displacement of the Sun relative to them were zero, X, Y, and Z would vanish, and the above equations would give A. Apart from errors of observation, M and M' would be entirely resolved into corrections to the adopted precession. If, on the other hand, we are dealing with a class of stars near the Sun, the displacements X, Y, Z will be large, and only a trifling part of the proper motions M and M' will be due to error of precession. In this section the stars are divided into groups according to the magnitude ' of their proper motion, and the value of the precessional constant n is deduced from the consideration that stars of small and large proper motion should give the same value of the ratio X : Y. The limitation of Groombridge's observations to within 52 of the pole would make the normal equations derivable directly from equation (ii.) unsatisfactory, and also, though not quite to the same extent, the equations derivable from (i.). In both cases X and An would be difficult to separate. Instead of treating ATI as an unknown quantity to be determined directly, equations have been formed giving the coordinates of the apex of the solar motions for stars with proper motion (l) between 0" and 5"; (2) between 5" and 10"; (3) between 10" and 20"; and (4) > 20" on two suppositions: First, basing the proper motions on the centennial value of the Struve-Peters' constants of precession, viz. : >n = 4607' "63 en INTRODUCTION TO GROOMBRIDGE CATALOGUE. Second, basing the proper motions on the centennial value of Newcomb's constants of precession, viz. : m 4607"' 1 1 n = 2005 - i i. This latter object was affected by applying a correction of + //< 52 cos S + 0"'53 sin S sin a to the centennial proper motions derived from the right ascensions and of + 0"'53 cos a to those derived from the declinations. Roughly speaking, this change in the precession adds + 0"'04 to the value of X derived from the right ascensions and + 0"'65 to the value derived from the declinations. The actual values found for X and Y are as follows : Right Ascensions. Declinations. Limits of P M. Struve-Peters. Newcomb. Struve-Peters. Newcombe.

DETERMINATION OF PRECESSIONAL CONSTANT. ciii From inspection of the above table it will be seen that whereas the values of A based on the Struve-Peters' constants of precession diminish with the magnitude of the proper motions, especially those depending on declination, the values of A depending on Newpomb's constants increase with the magnitude of the proper motions. Thus a correction of about one-third of the difference of the two values will make a very good agreement between the stars of large and small proper motions both for the right ascensions and declinations. In the last section a correction of +0"'65 was found to Newcomb's centennial value of m (4607"'ll) which implies a correction to n of $ x 0"'65 or + 0"'28, and the present reasoning requires a correction to the same constant of about ^ x 0"'53 or + 0"'17. We have adopted as the correction to n, + 0"'20 and to m, + 0"'46, giving for the centennial values of the precessional constants m and n for 1850 M=2005 '31 that is an increase to Newcomb's value of The following values of A corrected for this new value of the precession and the systematic correction Aa a (p.c.) as explained above, may be compared with the corre- sponding quantities on the opposite page.

XII. THE SOLAR MOTION. The difficulties which are inherent in the determination of the direction of the solar motion are illustrated to some extent in the statistics of the distribution of the stars, pp. xci-xcv. We found there (i.) Want of uniformity in the distribution of the stars, (ii.) Want of uniformity in the distribution of the proper motions. To elucidate the extent of the uncertainty of the result which might be expected from these indications of systematic differences in the distances of the stars in different parts of the sky, separate determinations of the direction of the solar motion are made in this section for (i.) Stars between definite limits of proper motion, (ii.) Stars of different magnitudes, (iii.) Stars whose spectra are of Types I. and II. As regards the formulae to be used, the simple and convenient method introduced 'by Airy has been employed. If X, Y, Z are the co-ordinates of the solar apex, then each proper motion in right ascension leads to an equation of the form X sin a Y cos a = fJ. ; and each proper motion in north polar distance to an equation of the form X cos a sin 6 -\- Y sin a sin 8 Z cos 8 = //.'. Also if M = the parallactic motion of a star 90' from the apex of the sun's way, A = the Right Ascension of the solar apex, D = the declination of the solar apex, then X = M cos D cos A. Y = M cos D sin A. Z = MsinD. The data on which the solutions are based are as follows : Nine stars of extremely large proper motion have been entirely omitted. All the stars whose proper motions are greater than 20" per century have been treated separately, equations of condition being obtained for each star, and normal equations formed and solved in the usual way. For stars whose proper motions are less than 20" a century means of the proper motions in right ascension and north polar distance have been formed for all the stars in areas approximately 10 square according to the following scheme : THE SOLAR MOTION. cv Limits of N.P.D.

When two stars appear to have a common proper motion they have been treated as one star. There will be found at the end of this section a list of the nine stars with proper motions too large to be used, a list of the stars with proper motions greater than 20" a century, also the mean proper motions in right ascension and declination, omitting the stars of large proper motion, for each of the 132 areas into which the sky from the pole to N.P.D. 52 has been divided. The data for the further subdivisions (e.g., Types I. and II. stars, &c.) are not given for each group, but mean proper motions for every 3 h of R.A. for the separate zones are given for stars of Types I. and II. All these proper motions are based on the Struve-Peters' constants of precession. The following solutions, however, depend on proper motions deduced with the new value of the precession (p. ciii.) and corrected further by the systematic correc- tions in R.A. given on p. c. All the proper motions in the following solutions are centennial proper motions. The general character of the normal equations is shown by the following example found for the 4001 stars whose proper motions are <20", giving equal weight to each star : From Rigid Ascensions. 195-8 X+ 24-6 Y= - 6*3 i 24-6 X + 205'2 Y= 4390) From Dei-lina/inn*. 133-8 X- 12-9 Y- 43-2 Z=-"iS'4i 12-9 X+ 122-6 Y + 16-9 Z= 202-9 43-2 X + 16-9 Y+144'4 /= +168-1 J from RiijJtt Axr'.-itsions anil Declinations. + 329-6 X + 11-7 Y- 43-2 Z=- 24-7 + 117 X+3277 Y+ 16-9 Z= -641-9 - 43-2 X+ 16-9 Y+144'4 Z= +168-1 CV1 INTRODUCTION TO GROOMBRIDGE CATALOGUE.

The proportion of stars between different limits of proper motion is also very regular. On this account these stars would seem to be very suitable for a determination of the direction of the Sun's motion, as the natural inference from their symmetrical distribution both in numbers and proper motions is that they are actually in space distributed symmetrically with reference to the Sun.

The progressive values of D under the groupings arranged according to magnitude. 4. Large as compared with small proper motions give a small value of D. 5. The small value of D given by the group of stars limited to 10"-20". In the following table all these different values of the position of the apex are collected together. ex INTRODUCTION TO GROOMBEIDGE CATALOGUE.

From a general consideration of these values of the solar apex the concluded value from this discussion is A = 275 D = + 37 Before leaving this subject, it may be well to set down the actual effects caused by the alteration in precession, and by systematic corrections on the values of the co- ordinates of the position of the apex of the sun's motion, and for this purpose we will take the general solution of 4001 stars with centennial proper motions ranging between 0" to 20". 1. If Newcomb's precession had been used the value of A would have been 279 and D would be unaltered. '2. The systematic corrections in R.A. given on p. c. diminish A between 2 and 3 and D bv 1. THE SOLAR MOTION. cxi 3. As a guide to the effect of a possible systematic error in N.P.D. it may be stated that for the mean Groombridge N.P.D. a constant correction of 0"'l would alter Z by 0""2 and the value of D by 4. XIII. LISTS OF PROPER MOTIONS. The following are the lists referred to on p. cv., and represent proper motions in arc, in R.A., and N.P.D. deduced directly from a comparison between the Groom- bridge and Greenwich Catalogues (the latter corrected to Newcomb's system) using Struve-Peters constants of precession.

ROYAL OBSERVATORY, GREENWICH NEW REDUCTION OF GROOMBRIDGE'S CATALOGUE OF CIRCUMPOLAR STARS MEAN RIGHT ASCENSIONS AND NORTH POLAR DISTANCES OF STARS OBSERVED BY STEPHEN GROOMBRIDGE, F.R.S., RR.A.S. AT BLACKHEATH FROM 1806, JUNE 16, TO 1819, APRIL 5 REDUCED TO 1810-0 NOTES As the Transit>circle used by Groombridge was a reversible instrument, the observations in the two positions have been kept separate in this section, East and West referring to the position in which the illuminator was to the East and West respectively. Proper motions (the adopted values of which are given in a list in the Introduction) have been applied to the daily results for those stars whose Groombridge No. is marked with an asterisk. All other stars in this section are reduced without proper motion. No correction for Division Error has been applied in this section. For the reduction to 1810-0 the Struve-Peters constants were used. LEDGERS OF GROOMBKIDGE'S OBSERVATIONS OF CIRCUMPOLAR STARS. Groonibridge No. Mean K.A. iSio'o. Mean X.I 1 . 1). iSio'o.

The miniler is left blank. The observation corresponding to the star's place in the original catalogue was made on 1810, Jan. 14, and has been rightly reduced, but no star can be found in this place. The R.A. is the same as No. 806, and has been assumed to belong to that star. The observation in N.P.D. has been rejected as erroneous. 807. The proper motion has been derived by comparison with observations made at Greenwich in 1897 and 1898. 812. This number is left blank. The observation corresponding to this star's place in the original catalogue was made on 1812, Dec. 13, and appears to have been really an observation in R.A. of 813, and in N.P.D. of 816.

NEW REDUCTION OF GROOMBRIDGE'S CATALOGUE OF CIRCUMPOLAR STARS. DEDUCED PROPER MOTIONS. 2 X NOTES. THESE Proper Motions have been derived solely from the comparison of recent Greenwich Catalogues with the Groombridge Catalogue, except in cases denoted by an asterisk, where the Radcliffe Catalogue has also been used. The references to the Greenwich Catalogue used are given in the third column of the previous section. The hours and minutes of Right Ascension and degrees and minutes of North Polar Distance for 1890'0 are given in the first column. Corresponding seconds for each of the catalogues are given in the columns headed R.A. and N.P.D. In the reduction to 1890'0 systematic corrections, but no proper motions, have been applied. The adjacent columns give the residuals of the different catalogues after the corrections for proper motion have been applied. The deduced proper motions are given for each star at the end of each group of positions and residuals. GROOMBRIDGE CATALOGUE DEDUCED PROPER MOTIONS. [3] Star's N, Una, and Approximate it. A. and N.
