INTRODUCTION. 
 
 General Historical Survey of Astrometry. 
 
 IN the present volume is condensed the record of three years' labour on 
 the Photometry of the stars visible to ordinary and unaided eyes, from the 
 North Pole, to about ten degrees South of the Equator. Estimations of the 
 relative brightness of these stars have been made from time to time by 
 various astronomers, but by none more successfully than by the illustrious 
 Argelander, who gave the results of his survey in the Uranometria Nova, 
 published at Berlin in 1843. It may not be too much to say of these 
 estimations that, taken as a whole, and viewed as estimations made without 
 the aid of graduated instruments, they are not likely to be surpassed in 
 point of precision ; yet it is not any disparagement of their intrinsic value 
 to add, that the requirements and progress of modern astronomy demand 
 greater exactitude than that which Argelander' s work justly claims, and a 
 precision exceeding any that can be expected from observations made with 
 the unaided eye. 
 
 In the place of these estimations, I now propose to substitute instru- 
 mental measures, made at the University Observatory in Oxford, with the 
 aid of a Photometer devised for the purpose by myself, and in which a 
 long and varied experience warrants me in placing a high degree of 
 confidence. 
 
 From time immemorial, reaching probably even far beyond the Homeric 
 epoch, the configuration of the stars in the heavens served, mainly through 
 their risings and settings, as a rough calendar for the regulation of the 
 dates of civil and religious proceedings, and for the purposes of agriculture 
 and navigation. There is a record that such configurations were depicted 
 on a Celestial Globe, constructed by Eudoxus four centuries before the 
 Christian Era ; and there can be no doubt that some method was at the 
 same time devised for the designation thereon of their relative brightness. 
 A copy or modification of this ancient Globe, supported on the shoulders of 
 a marble Atlas, was dug up from the ruins of Rome, and now furnishes one 
 of the most interesting objects of antiquity in the Royal Museum at Naples, 
 placed there by the munificence of Cardinal Farnese. It may be mentioned in 
 passing that the configurations of the constellations on this Globe are 
 substantially the same as those recognised at the present day.

iv Introduction. 
 
 But it is to Ptolemy, in his immortal work the MeyaArj 2wrats, or 
 Almagest as it was termed by his Arabian translators, that we are indebted 
 for a record, not only of the celestial co-ordinates of the stars visible in his 
 day (cir, A.D. 150), at Alexandria, but also for a catalogue of their relative 
 brightness, such as he had himself probably received from Hipparchus and 
 his predecessors more remote. It is a remarkable instance, among many 
 others, of the incisive intellect of the ancient Greeks, that they adopted not 
 only an admirable nomenclature for stellar brightness, which has remained 
 substantially unaltered to the present day, but one which even in its 
 minuter sub-divisions has been but slightly improved by modern astro- 
 nomers. It is still more remarkable that in this ancient and conventional 
 nomenclature, they practically but unconsciously anticipated an important 
 and fundamental law in Photometry, the first verbal expression of which 
 was brought into prominence by Fechner at so recent a date as I859 1 . 
 
 These ancient astronomers, as is well known, divided the brightness of 
 the stars, conceived by them under the thought of ' Magnitude ' (Me'yetfos) 
 into six classes. They assigned the ' first magnitude ' to a small group of 
 the brightest stars, and then proceeded step by step in successive groups to 
 the sixth, which included all stars shining with the feeblest lustre admitting 
 of appreciation by the naked eye. There was again in Ptolemy's catalogue 
 a sub-division of each magnitude into three, an amount of precision which 
 seems to have been subsequently abandoned for a long period by his 
 successors. It was, however, a nomenclature resumed by Flamsteed and 
 adopted by Argelander in his Uranometria Nova, and perhaps it is not too 
 much to say that a finer or more delicate sub-division of stellar lights, than 
 that denoted by the third of a magnitude, is not readily, and by direct 
 means, ordinarily appreciable by the human eye. 
 
 These tabulated magnitudes of individual stars, recorded in the 
 catalogues of Ptolemy, remained practically unimproved from his day 
 to that of the elder Herschel at the close of the eighteenth century. 
 Nevertheless the majority of those who flourished in the long line of 
 eminent astronomers between these distant intervals, did make some few 
 and feeble attempts to improve estimations, which they could not do other- 
 wise than feel, were not more than provisional. Among these the most 
 honourable place must be assigned to Abd-al-Rahman Al Sufi, who, about the 
 year 930, re-examined Ptolemy's work by a comparison with the heavens 2 . 
 Tycho (cir. 157) made no advance herein; the same remark applies also to 
 Hevel (cir. 1680). It might have been expected that Bayer, when, in A.D. 
 1 60 1, he bestowed on astronomers the memorable boon of a new nomen- 
 clature of the stars in their several constellations, through the application to 
 them of the letters of the Greek alphabet, would have availed himself of the 
 golden opportunity thus afforded him for a re-examination of the ancient

 magnitudes. Unaccountably, Bayer allowed the opportunity to pass, and 
 thereby laid himself open to the caustic remark of Delambre, as to the cheap 
 rate at which he had acquired immortality. 
 
 Finally, Flamsteed (cir. 1689), the first astronomer who applied the 
 telescope to systematic celestial measurements, re-introduced the sub-divisions 
 of a magnitude into thirds, by means of the notation now in general use ; but 
 in other respects exhibited either negligence or unconcern in his estimations 
 of relative stellar brightness. It was this disregard of precision on 
 Flamsteed's part which mainly induced Sir William Herschel l to turn his 
 own attention to the subject. 
 
 Penetrated with the importance of some record whereby obvious variations 
 in the brightness of stars could be ascertained ; important, not solely on the 
 side of inevitable curiosity, but from the consideration that our own star, 
 the Sun, might itself be variable in light and heat, William Herschel (cir. 
 1796) set himself to the task of forming that record, after his own manner 
 and from his own resources. With this view, he did not propose to verify 
 or improve Ptolemy's magnitudes, and still less those of Flamsteed, but he 
 adopted a more practical expedient, leading, as he rightly thought, both to 
 greater exactness and to greater utility in the direction of the variability 
 intimated above. Accordingly, he divided a constellation into small groups 
 of two, or three, or four stars of nearly equal brightness, and he then arranged 
 the stars in these small groups in the order of their lustre. One star might 
 in this way be found in more groups than one, and thus might furnish the 
 means also of connecting several groups together. Beyond this, he 
 attempted with much success to designate the degrees of the various 
 differences in lustre, not by numerical sub-divisions of magnitude as had 
 heretofore been the expedient, but by the introduction of symbols such as 
 dots, commas, semicolons, &c., placed between the stars whose brightness 
 was compared. For instance, in his nomenclature, a dot placed between two 
 stars would indicate all but absolute equality in brightness, the second star 
 however being, if anything, somewhat less bright than the star which 
 preceded the dot. A comma between them would indicate a somewhat 
 greater difference of brightness, and so on. It is due to the reputation of 
 this great practical astronomer to state that, on a photometric examination 
 of the small differences of light indicated by some of these symbols, there 
 is a precision and a consistency generally observable, which excite 
 admiration. 
 
 It was evidently no part of Sir William Herschel's intention to form, or 
 even to lay the foundation for forming a systematic catalogue of the 
 brightness of the stars ; but, as already intimated, it was his intention to 
 record the means of detecting any, the slightest, variation which might 
 occur at future periods in any of the stars forming any one of his groups. 
 These groups or short sequences are so numerous that they have not 
 unnaturally induced some astronomers to attempt the deduction therefrom

 of a complete catalogue of brightness systematically and numerically 
 arranged. Such an unavailing attempt has been made by the author of the 
 present volume, and, could it be successful, the value as a record would be 
 great indeed. But the groups are often so unconnected, the lacunae are so 
 numerous, and although the estimates of light between stars in the same 
 group are for the most part unimpeachable, nevertheless these considerations 
 render a complete catalogue of magnitudes, considered as Herschelian, 
 unattainable. The danger consists in the liability of importing so much 
 from the observations, whether photometric or otherwise, of other 
 astronomers, as would (and, in fact, do) render the final result, not so much 
 Herschel's unmixed production, as the reflection therein of other catalogues 
 formed by these astronomers. It must be here repeated, that these remarks 
 are not meant as the slightest disparagement of the illustrious astronomer's 
 work, for in this matter nothing was probably less in his mind, than the 
 formation of a systematic record of star magnitudes. 
 
 Sir John Herschel, however, during his busy life at the Cape of Good 
 Hope (1835-1838) did, in his mind, propose to complete the Astrometry of 
 the Heavens so far as was visible to the naked eye. His object appears to 
 have been, through loyalty to his father's memory, and for the permanent 
 advance of Sidereal Astronomy, to apply to the Southern Heavens that 
 same sort of scrutiny on which the latter had so long laboured at Slough, with 
 regard to the Northern. The process which he adopted was to divide the 
 stars visible to the unaided eye, into many sets of long and interlacing 
 sequences arranged in graduated lustre. These, when completed, he con- 
 sidered would furnish him with a systematic catalogue of magnitudes, 
 possessing far greater accuracy than any that had heretofore existed. 
 This plan, it will be observed, was generically different from that adopted 
 by the elder Herschel, whose aim was confined to the comparison of stars 
 divided into small sets of nearly equal brightness. While Sir John 
 Herschel was engaged in this project, and in the midst of others of 
 greater magnitude, he invented a photometer, by means of which he hoped 
 to arrive instrumentally at the same sort of results which heretofore he 
 and his predecessors had sought from estimations alone, though now with 
 far greater precision. The implement he devised was of rude construction, 
 such as could be arranged from the scanty resources of a distant colony, 
 but it was, in principle, sufficient for his purpose. Koughly described, it 
 consisted of a pole, a prism, a small lens of short focus, a few strings and a 
 graduated tape. With these materials properly arranged, he could obtain, 
 in the focus of the lens, a microscopic image of the moon, and this he 
 could view in any direction, and at any measured distance from the eye, 
 so that being brought into the same line of sight with any particular star, 
 he could alter the distance of the tiny image, until it and the star appeared 
 to be equally bright. In this way, the brightnesses of some sixty-nine stars 
 were compared with that of a Centauri, and the results were tabulated. 
 These relative light intensities, and the results of the sequence-observations 
 were then expressed in magnitude, in such a way and on such a scale as

 best to accord with the accepted magnitudes contained in the best catalogues 
 then extant. 
 
 The details of the process, at once ingenious and complicated, can be 
 mastered only by a reference to the original account given by the Author 
 in The Cape Observations. Unfortunately the entire project was not com- 
 pleted. An interesting comparison of some of the results with those ob- 
 tained by the Oxford Photometry will be found in Vol. XLVII of the Mem. 
 E.A.8., and more elaborate descriptions will be found in. the Photometric 
 Researches at Harvard College both by Mr. C. S. Peirce and by Professor 
 Pickering. 
 
 About the same time that Sir John Herschel was engaged in his astro- 
 nomical observations at the Cape of Good Hope, Argelander was at work 
 at Bonn, on the similar work of Astrometry ; but fortunately, with this 
 difference, that he was able to complete it. In 1843 he published his 
 Uranometria Nova, containing the estimated magnitudes of all the stars 
 visible to the naked eye in central Europe. This, in fact, is the first success- 
 ful attempt made by modern astronomers to arrange in an original and 
 independent catalogue, the relative brightness of the stars, and it must 
 ever remain a striking instance of what can be achieved by well-directed 
 perseverance and accurate discernment. Argelander has not recorded the 
 details of the method which he adopted to secure his results, nor is it 
 possible to say by what means or mental impressions, he preserved a fair 
 uniformity of scale, and a general conformity to the magnitudes recorded 
 by his predecessors. It may be sufficient to say that some not incon- 
 siderable variations of light-ratio do occur, depending on magnitude ; but 
 such variations are unavoidable, when the scale is the result of mental 
 impressions, rather than an instrumental measure. 
 
 Argelander's work was soon followed by another of still greater mag- 
 nitude and importance in which he, with the most able assistance of 
 Drs. Schonfeld and Kreuger, has recorded the approximate celestial co- 
 ordinates and the magnitudes of no fewer than 324,000 stars. In this case 
 the magnitudes are such as they are estimated to be, when seen through 
 the telescope, and not, as in the Uranometria Nova, observed with the eye 
 alone. If there are found some slight variations both in the magnitude of 
 individual stars, and in the light-ratios existing in the general estimate of 
 the larger intervals, the cause is to be sought in the same sources of imperfec- 
 tion as those just referred to in the case of the Uranometria Nova. 
 
 More recently, the heavens have again been scrutinized by Heis, at 
 Munster, who has re-examined Argelander's Uranometria Nova and has 
 added a considerable number of stars of a fainter lustre ; but many of these, 
 it is not too much to say, are beyond the vision of ordinary eyes. Houzea, 
 also by observations made during a residence for that purpose at Jamaica, 
 has rendered good service to astronomy, by publishing the results of his 
 own estimations. The same remark applies also to the astrometry of 
 M. Flammarion at Paris. Dr. Gould has recently enriched the resources 
 of astronomy by his astrometry of the southern heavens, with a degree of

 excellence such as to have been crowned by the bestowal of the Gold Medal 
 of the Royal Astronomical Society. 
 
 Instrumental Aids to Sidereal Photometry. 
 
 Contemporaneously with Herschel's invention of the rude, but ingenious 
 photometer at the Cape, Steinheil at Munich was arranging a more refined, 
 if not more accurate instrument, which was subsequently employed by 
 Seidel. It consisted of a small telescope, with a divided object-glass, each 
 of the halves of which was furnished with a reflecting prism, so that by 
 means of suitable mechanism, the images of two stars might be viewed side 
 by side in the telescope. The two halves of the object-glass were capable 
 of motion in the direction of the axis of the telescope, so that the images 
 of the two stars, when diffused into small discs, might be equalized in 
 brightness, by placing the respective object-glasses at different measurable 
 distances from the eye-piece. In this way, the intensities of a considerable 
 number of the brighter stars were compared. Seidel, however, did not 
 reduce his results to magnitude, but left them as logarithms of light, com- 
 pared with that of Vega, considered as unity. It is difficult to correctly 
 estimate the precision of Seidel' s results, but an interesting comparison of 
 his measures, set side by side with Herschel's, will be found in Vol. XLVII of 
 the Roy. Ast. Soc. Memoirs. Seidel also used his instrument successfully, in 
 measuring the amount of light lost by a star, through absorption in 
 passing through the Earth's atmosphere. Practically he verified Bouguer's 
 results obtained in 1725 ; he expresses some surprise at the comparative 
 exactness of the verification : but subsequent researches, and among others 
 those of the author of this volume, have confirmed the substantial accuracy 
 of their determinations. 
 
 Zbllner also devised a Photometer in which he successfully applied 
 Arago's suggestion 1 of the method of polarization. The comparison star in 
 Zollner' s instrument was formed artificially by means of a lamp, the light 
 of which could be reduced by double refraction through a measurable 
 quantity, until it was judged to have the same intensity as that of any 
 required star, in the same field of view as the artificial star itself. This 
 form of photometer has been in considerable use, chiefly by Zollner 2 himself, 
 by Pierce 3 , Wolff 4 , Miiller 5 , Lindemann 6 , and others. The unavoidable 
 want of uniformity in the light of the lamp, and the impossibility of imi- 
 tating exactly the appearance of an actual star, are fundamental difficulties 
 in the use of this otherwise convenient and ingenious instrument. Zollner 
 considered that he could imitate the colour also of a star, by the intro-

 duction of suitable polarizing apparatus, between his lamp and the eye-piece 
 of the telescope ; but the success of such an arrangement is doubtful. 
 
 An improvement both on Seidel's and Zollner's instruments has been 
 devised by Professor Pickering at Harvard, to which he has given the name 
 of Meridian Photometer, and in which he dispenses with the divided object- 
 glass of the former, and the lamp of the latter. There is a telescope tube 
 placed horizontally at right angles to the meridian in which is placed two 
 object-glasses, with their axes slightly inclined to each other. Each object- 
 glass is 4 centimetres in diameter, and is armed with an adjustable reflect- 
 ing prism. By these means, images of Polaris and of any star near the 
 meridian, may be formed in the common focal plane of the two object- 
 glasses, after having passed through a suitable combination of double 
 refracting prisms ; and then polarized images of the two stars may be 
 equalized, and their brightness ascertained. Pbr a fuller description of the 
 instrument recourse must be had to the original memoir of its inventor 
 forming Vol. XIV of the Annals of the Astronomical Observatory of Harvard 
 College. The construction is somewhat intricate, but if it be practicable to 
 bring all the light falling on the two object-glasses, effectively through the 
 double refracting arrangements, into the pupil of the eye, and then to afford 
 adequate time for the necessary repetitions of the equalizations, then this 
 form of photometer seems to offer very great advantages in stellar photo- 
 metry. By means of it, Professor Pickering and his assistants have 
 produced a catalogue of photometric measures, of all stars reputed to be 
 equal to or brighter than the sixth magnitude, visible at Harvard, for which 
 the permanent gratitude of astronomers will be accorded. Professor 
 Pickering has also applied the principle of polarization of light to the 
 photometry of double stars with success ; but the question of the equali- 
 zation of some of the more vividly coloured stars still remains of doubtful 
 solution, and it may be is beyond the reach of physical considerations 
 alone. 
 
 The method of photometry by means of varying the telescopic aperture 
 has received a new and practical development at the hands of Mr. Knobel. 
 By using the mirrors of a Newtonian telescope, one or both of them in an 
 unsilvered condition, he has contrived, on what appear to be unimpeachable 
 conditions, to extinguish the light of stars, well visible to the naked eye, 
 and thereby is enabled to compare their relative magnitudes ^

 The instrument with which the researches in this volume were made, 
 differs generically from all the preceding photometers, unless indeed the 
 eye itself be regarded as therein displacing or virtually , performing the 
 functions of Zollner's lamp and artificial star of comparison. It is con^ 
 structed on the principle that light in passing through a transparent homo- 
 geneous medium, loses an amount of intensity depending on the thickness

 of the latter. Hence it is easily shown, that if L represent the intensity of 
 a small pencil of light incident perpendicularly on a medium bounded by 
 parallel plane surfaces, such as a rectangular prism of neutral tinted glass 
 of the thickness r, it will emerge as a similar pencil with an intensity Z', 
 such that

 where K is some constant dependent on the material of the glass and the 
 nature of the light. 
 
 If then in passing from any one * magnitude ' to the next fainter, we 
 adopt a constant light-ratio of (p), and if L n , L n+x represent the intensity 
 of two lights whose magnitudes are n and n -f #, forming the incident and 
 emergent pencils, we shall have

 i. e., the light lost in passing through the medium^ measured by the alteration of

 which it has passed. 
 
 The above is the fundamental principle on which the wedge photometer 
 is constructed. This general principle had been applied by Mr. Dawes 1 
 and by others, but owing to various circumstances of misconception, and 
 the unavoidable difficulties in the earlier manipulation, no definite or 
 systematic results were then obtained. 
 
 The wedge photometer as employed at Oxford is a wedge of very nearly 
 neutral tinted glass GDF, six and a half inches long, an inch broad, and 
 0.145 i ncn thick, tapering off to D, where it is 0.02 inch. Cemented to it 
 is a similar wedge GDH, of white glass, placed the reverse way. The 
 whole forming a rectangular prism. This glass prism or * wedge ' as it will 
 henceforth be called, is enclosed in a brass cellular rim with bevilled edges, 
 one of which is divided into tenths of inches, the divisions being distinct 
 and white for visibility at night. It slides in a groove on the brass cap of 
 the eye-piece of any telescope, close to the achromatic eye lens, and is thus 
 placed between the eye of the observer and the telescope. In the focus of 
 the eye lens is a diaphragm, pierced with a number of small holes, which 
 vary from the hundredth of an inch to a quarter of an inch in diameter, and 
 in which small circular hole the telescopic image of a star is carefully 
 placed, and there viewed through the wedge. Further, the eye of the 
 observer is directed along the axis of the lens and of the telescope, by 
 means of an external eye hole, placed close to the wedge, and varying 
 from one-twelfth of an inch to a quarter of an inch. This direction of 
 vision is important. A fiducial mark is drawn on the brass cap of the eye- 
 piece, so that the position of the wedge can be distinctly marked and 
 recorded when the image of the star is just extinguished by the wedge. Usually 
 the position of the wedge, when the light of the star is just extinguished, is

 observed five times, and the mean of all the five readings is called the ' wedge 
 reading! The extinction of a second star is then observed in a similar 
 manner, and the difference between the two wedge readings is called the 
 ' wedge interval! This wedge interval is obviously a measure of the differ- 
 ence of the thicknesses of the neutral tinted glass of the wedge at the 
 points where the two stars are respectively extinguished ; and it will soon 
 be shown that this ' wedge interval ' is also a direct measure of the differ- 
 ence of the ' magnitudes ' of the two stars whose lights are respectively 
 just extinguished at the two points on the wedge. 
 
 Suppose J/j to be the magnitude (expressed as a number) of the star's 
 light incident at A, M and M" the magnitudes of these lights as reduced 
 by absorption in passing to C and B respectively. Then from the 
 preceding considerations 
 
 M^'-M^=K' .CB, 
 hence M^-M^ = K'(AB-^AC)+K .AC = K'AB + (K-K')AC 
 
 = constant + K"AD where K, K', K" are constants. 
 
 Next suppose the light of a second star incident at A' to be viewed 
 through the wedge and of which the incident magnitude is M 2 , then as 
 
 bef re M 2 "-M 2 = constant +K"A'D. 
 
 In the actual case of moving the wedge to such positions that the stars 
 are just extinguished M{' and M is the limit of vision of faint lights by 
 the observers, so that M^'= M and consequently 
 
 M 2 -M 1 = K"(AD-A'D) = K"AA'. 
 
 This is the fundamental equation of the wedge, expressing the law and 
 the amount of its action on light. It also follows, as already stated, that 
 if the wedge interval A A ' which corresponds to a reduction of light by one 
 magnitude, is found, then the constant K" is the reciprocal of the number 
 of inches in AA '. Or, in fact, if the wedge interval corresponding to the 
 reduction of any given number of magnitudes or portions of a magnitude 
 could be found, this would also give the value of the constant. 
 
 The first method which occurred for finding this constant was the 
 presumed property of light, that if the linear aperture of an object-glass be 
 
xii Introduction. 
 
 halved the light of a star would be reduced accurately and exactly to one- 
 fourth of its light, when viewed with the full aperture. In order to 
 exhibit this constant in a convenient numerical form, it is necessary to fix 
 upon some numerical value for the light-ratio (p). Several values have 
 been proposed, among others (2) was proposed by W. Struve 1 as, in his 
 judgment, fairly representing th6 sort of light-ratio which may be detected 
 in the ordinary estimations of magnitude. A much better ratio was pro- 
 posed by Mr. Pogson 2 , who in 1852 assisted Mr. Johnson, at the Radcliffe 
 Observatory, viz. p = 2.512 ... a number whose logarithm is .4, and this 
 ratio being at once convenient and fairly representing the ordinary tabu- 
 lated magnitudes, meets with a general acceptance among astronomers. 
 
 Now the result of an immense number of measures made with one of the 
 two wedges (designated as wedge A) in the present research was, that the 
 mean wedge interval required for the absorption of the light of one magni- 
 tude is 0.514 inch. But for various reasons, chiefly because an object-glass is 
 not uniform, either in thickness or in material, I was not satisfied with the 
 strict accuracy of the result. Accordingly, I proceeded to examine the wedge 
 A, (and subsequently the wedge B) by means of double refraction, or polariza- 
 tion of light, as explained in Vol. XLVII Mem. Eoy. Astr. Soc. The wedge was 
 examined for the amount of absorption at intervals of every tenth of an 
 inch from the one end to the other. A very slight, but not altogether 
 insensible, want of uniformity was discovered in the wedge itself, and the 
 inexactness of the method of apertures referred to above was confirmed. 
 In the mean it was found that the wedge interval corresponding to a 
 difference of absorption amounting to one magnitude on Pogson' s scale, was 
 0.539 inch, instead of 0.514 inch. As the result of a very extensive series of 
 comparisons the following table was drawn up. From this table it is to be 
 inferred, that at one inch from the thinner end, the difference of absorption 
 at the beginning and end of the inch amounts to i .93 magnitude, instead of 
 the mean amount 1.896. At two inches from the end, the difference of 
 absorption for an interval of two inches is 3.81 mag., instead of twice the 
 mean amount or 3.79 mag., and so on.

 This completed the theory of the wedge so far as ordinary white light 
 was concerned, and as applicable to the great majority of stars. But as a 
 not inconsiderable number of the latter exhibit colour more or less decided, 
 it seemed desirable to test the wedge in respect of such colours as could be 
 produced from coloured glass and coloured solutions of a definite optical 
 character, in regard to their spectra. The result was that in the case of 
 coloured lights not violently or very strongly pronounced, the wedge was 
 found to be equally absorbent throughout, and the mean wedge interval for 
 one magnitude of such light was found to be the same as for white light. 
 To this point it will be necessary to refer again, in considering the sources of 
 error that might be supposed to effect the results given in this volume. 
 
 It should be here noted that a second wedge (B) was examined in the 
 same manner as the former. (A). The material and general construction 
 are the same, with the exception that it was made a little steeper for 
 convenience and control over the other. This wedge was found to be 
 practically uniform throughout, and the wedge interval for one magnitude 
 was found to be 0.385 inch. 
 
xiv Introduction. 
 
 The Method of using the Wedge Photometer. 
 
 About ten stars were selected for a night's work, such that they could be 
 observed at nearly the same altitude as Polaris, in order that it might not 
 be necessary to correct the measures for absorption of light by the atmo- 
 sphere. The two Photometers A and B were attached to two telescopes, the 
 one of four inches, and the other of three inches aperture, each telescope 
 being in a separate dome ; the four-inch telescope being under the charge of 
 Mr. Plummer the Senior Assistant, and the other, under Mr. Jenkins the 
 Junior Assistant : each observer was independently to measure the several 
 stars specified. The complete plan was that Polaris should be extinguished 
 at the beginning, the middle, and the conclusion of the observations. The 
 readings of the wedge were taken five times with the full aperture of the 
 two telescopes. A cap was then placed on each object-glass, reducing the 
 linear aperture to one half, and five readings for extinction were again 
 made. The reason for thus altering the aperture was to establish thereby 
 a check on the former sets of five measures by means of a virtually new 
 instrument. 
 
 Each of the other stars whose magnitude was to be compared with that of 
 Polaris was then observed altogether with twenty extinctions, consisting of 
 four independent sets of five extinctions. The wedge readings were usually 
 brought to me on the following morning, and were reduced to magnitude by 
 the method shown in the example on page xxi, on the scale that the magnitude 
 of Polaris should be 2.05. If during the observations any suspicious cir- 
 cumstance had arisen regarding the clearness of the sky in the neighbour- 
 hood of Polaris or of the stars observed, the sky was scrutinized out of 
 doors and the observations if necessary discontinued. 
 
 The observations of a few nights, which in prudence might properly 
 have been rejected at the time, on account of an unfavourable sky, but 
 which have been inserted in the Memoirs of the Roy. Astr. Soc., have been 
 displaced in the present volume by the substitution of measures, taken under 
 more favourable circumstances : such cases are invariably mentioned in the 
 notes to each constellation. 
 
 In order that a correct judgment may be formed of the amount of 
 precision, which may on the average be expected to prevail in the results 
 given in this volume, I now append a tabular exposition of the individual 
 determinations of sixteen stars, each of which has been observed on at least 
 ten separate nights, and most of them with one hundred and twenty 
 extinctions in the aggregate. Each determination is derived from measures 
 made by both observers, with their separate instruments. The result will 
 be found to be, that provided the meteorological circumstances are favour- 
 able, little or nothing is gained in point of accuracy over a single night's 
 work of the twenty extinctions, by any multiplication of the measures. 
 From an inspection of the notes attached to the Catalogue, it will be 
 observed that this remark also is fully borne out in the case of a large 
 number of other stars, which have been more or less frequently observed.

 In explanation of the above table, the case of /3 Ursse Majoris may be 
 taken ; read in full it is virtually stated in the table that determinations of 
 the magnitude of this star were made on ten nights, extending from

Freedom of Measurements from influence of background, xvii 
 
 number of extinctions one hundred and ten. Similar explanations apply to 
 all the sixteen stars. I may observe in passing that /u Andromeda and 
 R. 204 Andromedse were observed for the purpose of watching the variations 
 of the Nova which broke out in the Nebula in September 1885. 
 
 This table contains many valuable elements for scrutinizing the amount 
 of reliance which may be placed on the Photometric records in this Urano- 
 metria. On comparing the results of twenty extinctions on one night with the 
 mean of those obtained from one hundred and ten extinctions on ten nights, 
 it appears that practically nothing has been gained in point of accuracy, 
 as far as these stars are concerned, by the multiplication of the observations. 
 
 The precision of the results, both as regards the capacity of the wedges 
 and as evidence of the care bestowed on the observations is, in every respect, 
 satisfactory. It will be noticed, that in the text, the magnitudes do not 
 exactly agree with the mean here set down. The differences are however 
 inappreciable, the reason of any slight disaccordance being, that the majority 
 of these observations were made, after the work had been sent to the press, 
 for the purposes of a stricter scrutiny than had hitherto been applied. I 
 have not selected these sixteen stars from a number of others, but I have 
 given all the records of stars so repeatedly observed. Many other stars 
 also have been frequently measured, but none so often as the above, and all 
 such cases of multiplied observations are given in the ' Notes.' 
 
 It will be observed that when ten extinctions have been made, the 
 results are not always quite so closely accordant with the mean as is the 
 case with twenty : but in general, and with few exceptions, the agreements 
 are highly satisfactory. An astronomer will not expect from photometric 
 observations that close accordance which he has a right to demand in 
 bisecting a division of a circle with a microscope, or in the transits of a 
 'Star across the wires of a meridian circle. It may also properly be 
 remarked that in stellar photometry the observer has no amplification 
 by lenses to assist him, but his attention is directed to the point of 
 disappearance of evanescent lights. Not only so, but the results here 
 given are differential, and dependent upon the errors of two fallible 
 measures. The circumstance, which though perhaps unexpected is not less 
 satisfactory, is the practical constancy of the physiological impression on the 
 organs Qf sight, which is unmistakably manifested by the accordance of 
 delicate measures, taken by two observers, using two instruments, under 
 varying circumstances, and during a considerable lapse of time. On ex- 
 amining the table, it will be found that the mean error of a single deter- 
 mination of magnitude, as given by ten or twenty extinctions, is under the 
 tenth of a magnitude. The mean error of a single extinction is .3 of a 
 magnitude. Of course, this is exclusive of any systematic errors, whether 
 of instrument or observation which might exist.

 notwithstanding the illumination of the background. In making this 
 remark, I wish it to be carefully noticed that I am here, and all along, 
 throughout these photometrical researches, confining myself to such dis- 
 criminations of variation of light as practically fall much within the limit 
 of the unavoidable errors of observation. I regard a variation of one- 
 thirteenth in the magnitude (or about seven per cent.) as the least intensity 
 of light which this instrument is capable of measuring when applied to stellar 
 photometry ; and, accordingly, in the remarks that I shall make, I shall 
 regard smaller variations of light than one-thirteenth of a magnitude as 
 practically not influencing the correctness of results ; and I know of no 
 measures of stellar light-intensity, excepting those made at Oxford, which 
 reach even this limit of accuracy. I admit that Fechner 1 has referred to 
 experiments on shadows, which show that the eye is, under special circum- 
 stances, capable of appreciating an alteration in the illumination of a sheet 
 of paper, arising from the introduction of about one-hundredth of the original 
 light. This experiment has been carefully repeated at the Oxford University 
 Observatory, and Fechner's result has been there verified by observations 
 also in an entirely different form. But it must not be overlooked that in such 
 researches, the comparison is made by means of the juxtaposition of illu- 
 minated surfaces of considerable extent. Moreover, the observation is made 
 with the use of both eyes. Independently of this, the method of shadows, 
 apparently so accurate, does not admit of application to the heavens. In 
 Steinheil's photometer, used by Seidel, the comparisons are indeed made 
 by the juxtaposition of stellar discs (or surfaces) not stellar points, as is the 
 case in the Zollner and in all adaptations of polarization to stellar photo- 
 metry, but in all these cases, including Steinheil's, the practical limit to the 
 discriminating power of the photometer, is from eight to nine per cent, of the 
 whole light 2 . 
 
 It is very necessary to bear these limitations in mind, in forming a 
 judgment of the reliability of the wedge photometer, when viewing stars 
 on faintly illuminated backgrounds, such as those which occur in practice. 
 This faint illumination arises from one of two causes, generically different 
 in character. The first is produced by the diffused or scattered light in the 
 atmosphere or sky ; the second arises from the presence of other stars in 
 the field of the telescope as limited in the photometer. Each of these 
 must be considered separately from the other. 
 
 When stars are viewed on moonlight nights with the wedge photo- 
 meter, it might probably be surmised (though not after due consideration) 
 that an effect would be produced on the measure of the light of a star 
 owing to this background. But, in the first place, it would be injudicious 
 to measure a star very close to the moon itself ; and in practice it would be 
 avoided. In the second place, it has been shown 3 practically, from the 
 examination of some five thousand extinctions of Polaris, made during 
 
 1 Leipzig, Abhandlungen der Mathematisch-Physischen Classe, p. 467. 
 
 2 See Wilsing, Astron. Nachrichten, vol. cix, p. 50, where, from experiment, he assigns a greater 
 probable error to the Zollner photometer than to the wedge.

 all phases of the Moon, that there is not the slightest trace observable of 
 effects due to moonlight or its absence. Nor indeed could it be otherwise ; 
 for the dispersed or scattered light of the atmosphere or of a blue sky, is not, 
 as in the case of stars, concentrated at the focus of the object-glass, but remains 
 very nearly as it would, if viewed with the tube alone from which the 
 object-glass and eye-piece are removed. Practically this scattered light is, on 
 a moonlight night, extinguished at one inch from the thinnest end of the 
 wedge, and long before a sixth magnitude star, or the faintest in this 
 catalogue, approaches extinction. 
 
 The second case contemplated is that in which other stars are present 
 in the same field of view with the star which is the subject of measurement. 
 The photometric field of view in the four-inch telescope is confined to a 
 circle of 0.02 inches diameter, equivalent to about 80". A reference to 
 Argelander's charts will indicate the fact, that in very few instances indeed 
 will so contracted a field, comprise, together with a sixth magnitude star, any 
 star ranging from the seventh to the tenth magnitude. A seventh magnitude 
 is very rare : if it be within (say) so" of the star to be measured, then it would 
 be placed in the category of double stars, and its character would be referred 
 to in the Notes. It would, if viewed as one point of light, coalesce with the 
 sixth magnitude, and the combined light would be of 5.6 magnitude. If, on 
 the other hand, the small star, or the two or three small stars in the field be 
 detached from the brighter star, they would produce distinct impressions on 
 the retina, and would be completely extinguished by the wedge long before 
 the extinction of the brighter, and could produce absolutely no influence on 
 its measure in the photometer. Precisely the same sort of reasoning applies 
 to the measurement of fainter stars in a larger telescope, say of twelve 
 inches or any greater aperture. The photometric field in such telescopes 
 is still more restricted, and the very faint stars possibly accompanying the 
 one to be measured, would either coalesce as a double or multiple star, and 
 be noted as such, or they would be extinguished by the wedge long before 
 the extinction of the brighter. 
 
 The effect of the coalescence of two stars upon the magnitude of the 
 brighter, is shown in the following short table :

xx Introduction. 
 
 These considerations are sufficient to indicate the practical freedom of 
 this photometer from the influence of the greater or less density of stars 
 illuminating various regions of the heavens (always within the limits of 
 accuracy prescribed). 
 
 So far, the above conclusions are drawn chiefly from abstract grounds. 
 Practically, a comparison of the photometric magnitudes of a large number 
 of stars between the fourth and six-and-a-half magnitudes has been made 
 with those given in the Harvard Photometry. Not a trace of any 
 systematic difference has been found in the magnitudes in the two catalogues, 
 so far as is due to the varying stellar densities of the regions where these 
 comparisons have been made l . 
 
 Another cause of conceivable error, and one to be guarded against in 
 the use of the photometer, arises from the possible fatigue of the eye during 
 any considerable series of measures on any single night, whereby the want 
 of constancy in the appreciation of faint lights, might operate unfavourably. 
 In order to assure myself of the non-existence of this sort of error, a 
 large number of extinctions of Polaris made on separate nights, have been 
 examined. These extinctions of Polaris are, as has been explained, made three 
 times on each night, viz. at the beginning, the middle, and the end of the 
 series. No trace of a systematic difference is found indicating symptoms of 
 varying sensitiveness of the observer's eye, depending on these sequences of 
 time. Moreover, as the measures are strictly differential, and as the mean of 
 the three sets of readings of the extinction of Polaris (which rarely differ 
 much inter se), is used for all the observations of the series, the mean condition 
 of the eye is represented throughout. In point of fact, relief is afforded by 
 continual breaks in the work of actual observation, connected with the 
 shifting of the domes, with the identification of the stars, and with the 
 recording the results ; the whole series also seldom occupies more than three 
 hours in the night. All these circumstances combine to prevent any undue 
 strain on the eye of the observer, during the limited time of his work. 
 
 The action of this form of photometer in relation to colour, seems to be 
 in pretty much the same category as any other photometer, not excepting 
 even Zollner's ingenious contrivance. The colours of the stars, with a few 
 well-known exceptions, are faintly marked. The action of the wedge on 
 such lights was carefully examined by means of coloured solutions and 
 coloured glasses, and by the spectroscope, as is detailed in the Memoirs of the 
 Eoyal Astronomical Society, vol. xlvii, pp. 395-6", and, as has been already 
 mentioned at p. xiii, no defect was discovered within the prescribed limits 
 of error of observations. The mat6rial of the wedge has a selective 
 absorption for the red part of the spectrum near to the line .Z?, and 
 every case of a star reported to have a red tinge, is referred to in 
 the notes appended to each constellation. It is, however, very remarkable 
 that out of all these numerous instances of stars of a more or less reddish 
 tint, there is very rarely any difference between the Oxford and the

 Harvard magnitude, greater than the mean difference for all the stars 
 examined in both catalogues. The question of colour seems to be, to a 
 very considerable extent, subjective and physiological, and, at present, out 
 of the domain of exact science. Possibly the arrangements described by 
 the present Astronomer Eoyal in the Monthly Notices, January 1874, may 
 be developed with success in this direction.

 The first column contains the date : the second is the record of the wedge 
 readings for each extinction of the star in the wedge A, with aperture four 
 inches, the mean reading of the five extinctions is 2.652 in. The second 
 column contains the three readings of the extinction of Polaris at the 
 beginning, the middle, and close of the observations. Their mean is 4.600 
 inches. The equivalent magnitude for 2.652 in Table I is 5.04, and the 
 magnitude for 4.600 in. is 8.60. Finally 8.605.04 = 3.56. This is the dif- 
 ference of magnitudes of the star and Polaris ; and as the latter is conven- 
 tionally 2.05 mag. the resulting magnitude of the star is, so far as this single 
 measure is concerned, 5.61. Similar wedge readings are then taken with 
 wedge A, after the linear aperture of the telescope to which it is attached 
 is halved. These measures, the mean of which is 1.862, are then combined 
 with the mean of the three wedge readings for Polaris with this aperture, 
 viz. 3.845. Kesort is then had to Table I, as before, for these two wedge 
 readings, whence the equivalent difference of magnitude of the star and 
 Polaris is derived, viz. 3.69, and the resulting magnitude of the star is 5.74. 
 In the remainder of the Table are given the details of the extinctions with 
 the wedge B, with apertures of 3 inches and i \ inches. The resulting mag- 
 nitudes of the star are 5.67 and 5.59. The final and tabular determination 
 
Observations taken at Cairo. xxiii 
 
 of the magnitude of 72 Tauri is 5.65. The mean deviation of the four 
 individual measures is .05 magnitude ; and if on several other nights the 
 determinations of the star's magnitude had been taken, there is little doubt, 
 judging by experience (see page xv), that the magnitude (5.65) would not 
 differ from the general mean of all by one-tenth of a magnitude. 
 
 Observations taken at Cairo. 
 
 It necessarily formed part of the scheme of photometric work at 
 Oxford to determine the amount of light absorbed by the earth's atmosphere 
 when a star is observed at any varying altitude. Without such deter- 
 mination, the research would have been incomplete, although, so far as the 
 stars in this Uranometria are concerned, a knowledge of the amount of this 
 absorption is rarely required, inasmuch as the stars are in general observed 
 at an altitude so near that of Polaris, that no correction is required for 
 absorption in order to obtain the zenithal magnitude of the star, because 
 the zenithal magnitude of Polaris is assumed at 2.05, and absorption would 
 act equally on the two if observed on the same night and under approxi- 
 mately the same atmospheric circumstances. The detail of the work for 
 the determination of the atmospheric absorption constant at Oxford is 
 all given in Memoirs of the Roy. Astr. Soc., vol. xlvii : the result being to show 
 the necessity of a correction to magnitude, of 0.253 sec ^ z - I was n t wholly 
 satisfied with this determination, excepting so far as it accurately represented 
 the local atmospheric absorption at Oxford, and I thought it desirable to 
 measure it again, in some other locality where the climate is more equable, 
 and the atmospheric circumstance in general more favourable, and more ac- 
 cordant measures might be anticipated. I was also desirous of ascertaining 
 what improvements might be effected in the determination of magnitude in 
 that climate. 
 
 Accordingly, I determined on a voyage to Cairo, taking thither Mr. 
 Jenkins, with the telescope and wedge A, hitherto used by Mr. Plummer. 
 I had carefully ascertained before making the exchange, that it was indif- 
 ferent which wedge was used by either of the two observers, notwithstand- 
 ing his habituation to the use of one particular instrument. In due time 
 the telescope and Mr. Jenkins were duly installed in the admirable ob- 
 servatory, belonging to the Khedive at Abbasseeyeh, within a stone's cast 
 of the English barracks in the desert. The atmosphere and climate proved 
 to be all that had been stated in their favour, and about three times as much 
 work was there effected in six weeks as was done, or in fact could be done 
 at Oxford: for it was a settled part of the plan, that Mr. Plummer in 
 Oxford was to make the same observations as Mr. Jenkins at Cairo. The 
 results of the expedition are all embodied in the measures recorded in this 
 volume, and greatly add to the confidence I feel in the general accuracy 
 of the work herein exhibited. The atmospheric absorption constant at 
 Cairo proved, as might be expected, slightly less than that at Oxford, but 
 
XXIV

 not so much less as I had anticipated. The climate during the time I was 
 in Egypt, February and March, was indescribably agreeable, and equable 
 to a degree unknown in England ; but its increased transparency was only 
 such as to admit of the partial visibility of stars exceeding those visible at 
 Oxford by about a fifth of a magnitude. Of course this addition to the 
 number of stars visible would be counted by the thousand rather than by 
 the hundred ; nevertheless the gain in transparency alone was in a telescopic 
 sense comparatively trifling ; in steadiness the advantage was enormous 
 during the time mentioned. Probably at other periods it is much less so, but 
 I speak here from conjecture. 
 
 The resulting values of atmospheric absorption expressed in magnitude

 I will only add that in the climate of Oxford and probably that of the 
 greater part of Europe the application of this formula is not safe beyond 
 60 or 65 from the zenith. In a climate such as Cairo it may probably be 
 trusted to 75 or 80 Z. D. But I have restricted the catalogue of this 
 Uranometria to such stars as it is possible to observe at a moderate distance 
 from the zenith or at the same altitude nearly as Polaris, and in this way 
 the difficulty is evaded. Generally speaking, when great accuracy of result 
 is needed it will be found necessary to restrict photometry to observatories 
 favourably situated for the purpose. 
 
 The result of the many fairly accordant determinations of the general 
 atmospheric absorption given above, obtained as they are by methods 
 widely different, leave no doubt of their approximate and practical accuracy, 
 with this reservation, that it may be admitted, they are not to be trusted as 
 representing facts anywhere near to the horizon. This remark may go 
 far to explain the doubts expressed by Professor Langley as to the general 
 untrustworthiness of the whole investigation from a theoretical point of 
 view. 
 
 Explanation of the Catalogue. 
 
 We are now arrived at the description of the Catalogue itself. The first 
 measure was made on Dec. 22, 1871 ; the last on Oct. 16, 1885. The stars 
 selected are strictly those in Argelander's Uranometria Nova, though but few 
 were measured in Oxford, below 10 south of the Equator, on account of the 
 uncertainty of the absorption correction for low altitudes, and of these few, 
 the adopted magnitudes are given in the Notes : not that the mean value of 
 this correction is so uncertain, but because my experience is, that it varies

 very sensibly from night to night. Where my work ends it may be more 
 properly continued at some Southern Observatory, and I trust I may be 
 permitted to hope, that as the precision of modern astronomy advances, each 
 observatory will confine its attention to that work alone, for which its 
 position and equipment especially fit it. With regard to celestial photo- 
 metry in Oxford, I should have preferred not to carry the observations 
 south of the Equator, but it seemed desirable to extend them to some 10 
 South, in order to provide an overlap for connecting the Oxford results with 
 those obtainable in some observatory in Southern Latitude. 
 
 I have adopted the arrangement of the stars in constellations, mainly 
 because the stars concerned are visible to the naked eye, and are more easily 
 cognizable than if the usual celestial co-ordinates alone were given. The 
 abbreviations made use of in the column of ' Star's designation,' and else- 
 where in the volume, are such as are generally recognised by astronomers 
 and consequently need no explanation. 
 
 I have given the estimated magnitudes of the Uranometria Nova, rather 
 than those in the Durchmusterung r , not only on account of the care which 
 Argelander bestowed on this special subject, but because the stars in the 
 larger catalogue were all observed telescopically, and therefore are derived 
 from the impressions of memory alone : nevertheless, I believe, the latter 
 represents faithfully the heavens as they are seen. The average deviation 
 from the mean of the usual twenty extinctions is given, rather than the 
 ' probable error,' because the latter term is liable to misinterpretation : 
 moreover, it must not be forgotten that this ' average deviation ' is a test, 
 rather of the general accordance of the individual extinctions with them- 
 selves, than of the actual accuracy of the final determination. This accuracy 
 may be better estimated from the inspection of the numerous measures on 
 different nights of the stars given on page xv of this Preface. 
 
 I have confined the Notes to calling attention to such features of the star 
 in question, which I considered worthy of notice, or likely to affect the 
 determination of magnitude. The spectra of stars are probably of far greater 
 importance and possess more significance than any indication of colour, 
 which not without some care is detectable by the naked eye : consequently 
 whenever there is anything remarkable in these spectra, I have directed 
 attention to the fact so far as the valuable observations of Dr. Vogel, as 
 given in the Publicatwnen des Astrophysikalischen Observatoriums zu Potsdam, 
 Nr. n, are concerned. Vogel's classes, described in his own words, are 
 
 CLASSE I, 
 
 Spectra, in welchen die Metalllinien nur ausserst zart auftreten oder gar nicht zu 
 erkennen sind und die brechbareren Theile des Spectrums, Blau und Violett, durch 
 ihre Intensitat besonders aufiallen. 
 
 (a) Spectra, in denen, ausser den sehr schwachen Metalllinien, die Wasserstoff- 
 linien sichtbar sind und sich durch ihre Breite und Dunkelheit auszeichnen. 
 
 (b) Spectra, in denen entweder einzelne Metalllinien nur ganz schwach ange- 
 deutet, oder gar nicht zu erkennen sind und die "Wasserstofflinien fehlen.

 CLASSE It. 
 
 Spectra, in denen die Metalllinien sehr deutlich auftreten. Die brechbareren 
 Theile des Spectrums sind im Vergleich zur vorigen Classe matter. In den weniger 
 brechbaren Theilen des Spectrums treten zuweilen schwache Banden auf. 
 
 (a) Spectra mit sehr zahlreichen Metalllinien, die besonders im Gelb und Griin 
 durch ihre Intensitat leicht kenntlich werden. Die Wasserstofflinien sind meist 
 kraftig, aber nie so auffallend verbreitert als bei Classe la. Bei einigen Sternen sind 
 die "Wasserstofflinien schwach, und bei solchen sind dann gewohnlich in den weniger 
 breehbaren Theilen schwache Banden zu erkennen. 
 
 CLASSE III. 
 
 Spectra, in denen ausser dunklen Linien noch zahlreiche dunkel Banden in alien 
 Theilen des Spectrums auftreten und die brechbareren Theile des Spectrums auffallend 
 schwach sind. 
 
 (a) Ausser dunklen Linien sind in den Spectren Banden zu erkennen, von denen 
 die auffallendsten nach Violett dunkel und scharf begrenzt, nach Roth matt und ver- 
 waschen erscheinen. 
 
 (b) Spectra, in denen dunkel, sehr breite Banden zu erkennen sind, von denen 
 die am starksten hervortretenden nach Roth scharf begrenzt und am dunkelsten sind, 
 nach Violett allmahlich erblassen. Sie erscheinen also nach der entgegengesetzten 
 Seite verwaschen, wie die Banden in den Spectren der vorigen Unterabtheilung, auch 
 ist ihre Anzahl geringer als dort. Das Blau und Violett ist gewohnlich iiberaus 
 schwach.

 Inasmuch as the photometry of stars exhibiting any salient colour 
 may be open to some doubt, I have noted all such cases, including all 
 Birmingham's stars, though the colours of many are often practically 
 not recognizable. 
 
 When the measures in this Uranometria were about three-fourths com- 
 pleted, the ' Harvard Photometry ' was published, and inasmuch as this 
 work is one of unquestionable importance, it became desirable to compare 
 the results there given, with my own. Wherever there was a difference 
 exceeding a third of a magnitude between the two catalogues, the stars were 
 re-measured at Oxford. In the great majority of instances, the previously 
 existing measures were re-obtained. Still, it may not be assumed that my 
 determinations are always free from error, and I have accordingly given the 
 Harvard magnitude, as well as the Oxford, but as all the stars in both cata- 
 logues are compared with Polaris, and as in the American Catalogue 2.15 is 
 assumed as its conventional magnitude, whereas 2.05 is assumed in this 
 Uranometria, it is necessary to subtract one-tenth of a magnitude from all 
 those to which H.P. is affixed in the Notes. I did not consider myself 
 warranted in taking the liberty of making the alteration in a more formal 
 manner. 
 
Explanation of the Catalogue. 
 
 xxvii 
 
 Until Sir John Herschel's photometric researches at the Cape had made 
 it possible to discriminate between the lustres of the brightest stars, these 
 were all grouped together as stars of the first magnitude, though in point 
 of fact they differed from each other enormously in respect of intensity of 
 light. When this fact became apparent a new nomenclature regarding such 
 stars became necessary. 
 
 The one adopted, that of the magnitude nothing, and still more the mag- 
 nitude minus, necessarily leads to confusion. I have therefore ventured to 
 propose another designation, to the effect that the symbol + placed before 
 a magnitude shall intimate that its lustre expressed numerically is so many 
 magnitudes or portions of a magnitude brighter than the first ; so that 
 + 0.4 and +1.3 shall indicate respectively, four-tenths of a magnitude, and 
 one and three -tenths of a magnitude, brighter than the first. In this way 
 the magnitude of Sirius is designated by + 1.95, indicating that it is very 
 nearly two magnitudes brighter than a star, such as a Aquilse or Spica, which 
 stars are very properly regarded as approximately of the first magnitude on 
 Pogson's scale. In connection with this I append the photometric 
 magnitudes of such stars as have heretofore been grouped together, as of the 
 first order of lustre.

 As a matter of fact, and not without some interest, it may be stated 
 that, on comparing the results of these photometric measures with the 
 telescope estimates of the same stars in the Durchmusterung, the mean 
 difference is found to be .06 in the magnitude of a single star. The two 
 catalogues, therefore, notwithstanding many individual discordances, may 
 in, the average, and on the whole, be regarded as in substantial agreement. 
 
 The researches in this volume, being the first that have been completed 
 on the instrumental photometry of the stars by an European astronomer, 
 must have historical relations. If, on examination, they shall also be found 
 to possess, as I confidently expect they will, an appreciable scientific value, 
 I desire to record that much of it is due to the skilful and unremitting 
 attention of my two assistants Mr. W. Plummer, F.R.A.S. and Mr. C. 
 Jenkins, F.R.A.S., by whom the necessary measurements, exceeding seventy 
 thousand, were made.

 No. 41. This magnitude (6.10) is the mean of two measures (6.12 and 6.08) observed with 
 twenty extinctions 1884.475, and with six extinctions 1885.327. H.P. = 5.84. 
 No. 44. This star is 2 1864, Dist. 6". The observation of 1882.370 is rejected. (See Note 
 to No. 5.) 
 No. 45. This star is 2 1865, Dist. i" '. The magnitude is consequently that of the combination. 
 The observation 1882.370 is rejected. (See Note to No. 5.) 
 No. 46. Gould suspects this star of variability. But the measure at Harvard, 4.99, accords 
 with the Oxford measure here given. 
 No. 48. Discovered by Schmidt to be variable in 1867, with limits of magnitude 5.2-6.1. 
 Schmidt's estimated maximum is too faint. 
 No. 50: Spectrum III a ! ! ! (Vogel.) 
 No. 51. This star is Birmingham No. 339 and 21877. The colours recorded vary from orange 
 to yellow. 
 No. 53. This star is 2 1884, Dist. i".2. Observed as one star. 
 No. 54. Gould's suspicion of the variability of this star is not supported by the Harvard and 
 Oxford observations, but the magnitude 6.95 seems too faint for its detection by Argelander. 
 No. 61. 2 1888, Binary. The larger component observed.

 The magnitudes of the stars in the Pleiades were compared directly with that of Me'rope, deter- 
 mined by measurement to be 4:30 on the scale of Polaris =2. 05 mag. 
 Other valuations of these magnitudes made by other Astronomers will be found in Memoirs 
 R.A.S., vol. xlviii, p. 272.
