INTRODUCTION. 
 
 Soon after I had the honour of being appointed Her Majesty's 
 Astronomer at the Cape, in 1879, I directed the attention of the 
 Lords Commissioners of the Admiralty to the fact that no 
 adequate equipment for refined extra meridian observations 
 existed at the Observatory. Before making further official 
 proposals to remedy this defect I had the good fortune to 
 procure, by private purchase, the Heliometer which I had used 
 at Dun Echt, and in connexion with the expedition of Lord 
 Lindsay (now the Earl of Crawford and Balcarres) to the Island 
 of Mauritius in 1874, when I observed with it the opposition of 
 the minor planet Juno,* and which I afterwards employed by 
 Lord Lindsay's kind permission, in the Royal Astronomical 
 Society's expedition to the Island of Ascension to observe the 
 opposition of Mars in 1877.t 
 
 The instrument as employed at Mauritius and Ascension is 
 fully described in the Dun Echt publications, Vol. II. For use 
 at the Cape I could not obtain the original equatoreal mounting, 
 and therefore ordered a new stand for the Heliometer tube and 
 cradle from Sir H. Grubb of Dublin, taking advantage of 
 the opportunity thus offered to have some alterations made on 
 the instrument which previous experience had proved to be 
 desirable. These alterations were chiefly in connexion with the 
 slow motion of the tube in position-angle. In the original 
 instrument the quick motion in position- angle was accomplished 
 by turning a rod, which carried a pinion which acted on a wheel 
 of which the Heliometer tube formed the axis. Slow motion 
 was given by rotating this rod very slowly by means of a 
 toothed wheel acted on by a tangent screw, but the effect was 
 to create a certain amount of torsion of the rod before any 
 rotation of the tube took place, so that there was wanting that 
 immediate and precise response to the observer's action which is 
 essential for easy and accurate measurement. I therefore planned 
 the following arrangement. 
 
 At the end of the cradle next to the observer, there is fitted 
 on the tube (or rather on one of the collars attached to the tube)

 a ratchet wheel with square cut teeth. This wheel is so fitted 
 as to turn smoothly on the collar, but, when the observer so 
 desires, it can be clamped firmly to the tube by a handle coming 
 down to the eye-end. A steei screw with a square-cut thread 
 (such as Grubb uses for the driving screws of his Equatoreals) 
 acts on the teeth of this wheel, whilst the pivots of this screw 
 rest in bushes in a frame attached to the cradle. The screw is 
 turned by bevel wheels acted on by a handle coming down to 
 the eye-end. When the observer turns the handle the wheel 
 slowly rotates; and, if the tube is clamped to the wheel, a 
 smooth easy rotation is communicated to the tube. This slow 
 motion as well as the Equatoreal mounting, and the driving 
 clock were admirably constructed by Sir. H. Grubb and the 
 instrument was in every respect efficient, stable, and convenient. 
 
 During a visit to some of the principal European observatories, 
 before my departure for the Cape, I met Mr. W. L. Elkin, a 
 student under Professor Winnecke, who was then engaged in 
 preparing his " Inaugural Dissertation " for the Degree of 
 Doctor of Philosophy at the University of Strasburg. The 
 subject he had selected was the orbit and parallax of a Centauri 
 and he applied to me for any observations of Centauri as a 
 double star, or any unpublished meridian observations of a )3 
 Centauri which I might find on the records of the Cape 
 Observatory.* In the course of conversation I informed Mr. 
 Elkin of my purchase of the Heliometer, and of the purposes to 
 which I intended to apply it. He expressed much interest in 
 my programme and his keen desire to take part in such work, 
 It was finally arranged that, on the completion of his curriculum 
 and on the arrival of the Heliometer, Dr. Elkin should come to 
 the Cape and share my labours. 
 
 The Heliometer reached the Cape in the end of December 
 1880 (the Lords Commissioners of the Admiralty having 
 defrayed the cost of transport), and I proceeded at once to erect 
 it in an old observatory which had been built by Sir Thomas 
 Maclear in 1847, to cover a small telescope by Dollond. This 
 observatory is described in Mem. R.A.S., vol. xx., pp. 31-34. 
 I had duly completed the necessary alterations of the building, 
 and the adjustments of the instrument when Dr. Elkin arrived 
 at the Cape, on 1881, January 31. The following month was 
 spent in preliminary experiments, in the selection of stars of 
 comparison, and in the preparation of a programme. 
 
 * These observations I supplied soon after my arrival at the Cape, and they are 
 incorporated in his Dissertation " Ueber die Parallaxe von a Centauri." Karlsruhe, 
 1880. 
 
This settled, I was en the point of leaving for Durban and 
 Aden to carry out the longitude operations connecting these 
 places with the Cape, when I was suddenly recalled to England 
 on urgent private affairs. I made new arrangements for the 
 longitude work, so that when I returned to the Cape on 1881, 
 June 30, I was enabled to take up the programme of the Helio- 
 meter observations at an earlier date than I originally intended. 
 Dr. Elkin occupied my house in my absence, and remained as my 
 guest, and as a member of my family circle until the completion 
 of our programme. He sailed from the Cape on 1883, May 16. 
 His work from first to last was a labour of love. 
 
 The results of the observations contained in this volume have 
 been published in the Memoirs of the Royal Astronomical Society, 
 vol. xlviii. ; but in connexion with such work it is usual and 
 desirable to publish sufficient details of the original observations 
 to enable other Astronomers to verify the subsequent com- 
 putations. 
 
 In the selection of comparison stars the conditions aimed at 
 were : 
 
 1. Symmetrical situation with respect to the star whose 
 
 parallax is to be determined, that is to say, nearly at 
 equal distances from it, and different in position-angle 
 nearly 180. As far as possible these position-angles 
 should nearly coincide with the position-angle of the 
 major axis of the parallactic ellipse, but when several 
 pairs of comparison stars are employed this condition 
 cannot of course be fulfilled. 
 
 2. Both comparison stars should be nearly of equal mag- 
 
 nitude. 
 
 3. They should be stars having little or no proper motion. 
 
 The following are the positions of the comparison stars as 
 determined with the Cape Transit Circle, and the adopted 
 position-angle and distance from the principal star ; the other 
 existing observations reduced to the same equinox will be found 
 in the Mem. R.A.S., loc. cit.

 A complete observation consists of the following processes : 
 
 1. The Position Circle is set to the required position-angle 
 
 and the segments separated in distance the requisite 
 amount. 
 
 2. The axis of the tube is directed, by means of the Hour and 
 
 Declination Circles, to the middle point between the stars 
 to be observed, when the images of the two stars are seen 
 together in the field of view. 
 
 3. The observer, by slow motion in position-angle and distance, 
 
 now brings the images to near contact, especially adjust- 
 ing the distance as nearly as possible. This latter adjust- 
 ment cannot be accurately made by superposing the 
 images ; the best practical method is to first place the 
 images of the two stars so that, while the discs are nearly 
 in contact, the line joining their centres shall be at right 
 angles to the direction of measurement. The estimation 
 of this condition is facilitated in two ways : 1st, the 
 images formed by semi-lenses are not circles but ellipses, 
 and when the definition is good and the stars are suffi- 
 ciently bright, the most accurate plan is to make the 
 major axes of the two ellipses coincident. The accuracy 
 of this estimation is greatly enhanced by immediate and 
 frequent interchange of the two images by use of the 
 slow motion in position-angle. The symmetrical emer- 
 gence of the elliptical discs from behind each other in 
 alternate opposite directions forms the most refined 
 method of " pointing " known to astronomers. When 
 the images are very faint or ill-defined, the power of 
 estimating distances in this way is not available, because 
 the major axis of the ellipse cannot be precisely distin- 
 guished. To provide for this, four flat intersecting wires 
 were inserted, in the common focus of the object glass and 
 eye-piece, forming a square, in the centre of the field, two 
 gides of the square are parallel to the direction of motion 
 in distance, and two at right angles to this direction. 
 The observer takes the latter pair of wires as his guides, 
 and by motion of the " distance-handle " adjusts the 
 position angle of the artificial close double star parallel 
 to the direction of these wires. This observation is 
 analogous to that, in which an observer with a parallel- 
 wire micrometer adjusts the wires parallel to the line 
 joining the centres of the double star whose position 
 angle he is measuring, but with this difference, that the 
 latter moves the position-angle of his micrometer till the 
 
Vlll 
 
 wires are parallel to the stars under observation, whilst 
 the Heliometer observer changes the apparent position- 
 angle of the artificial double star by motions of his 
 " distance-handle " until the line joining the components 
 is parallel to his guiding wires. Immediately " crossing 
 through " (i.e., exchanging the relative positions of the two 
 stars), he verifies his former observation, and, if he finds 
 it confirmed, proceeds to read the scales. The eye is 
 very sensitive to the symmetrical crossing of the stars and 
 readily detects any apparent change of parallelism in the 
 guiding wires as such error in the first pointing is doubled 
 after " crossing through." 
 
 The accuracy in pointing by either of these methods is greatly 
 enhanced when the two images are precisely similar, hence the 
 great attention paid to the construction of the screens employed 
 to equalize the images. These screens were constructed of one, 
 two, and three thicknesses of wire gauze of different mesh, and 
 by careful selection and trial little difficulty was found in pro- 
 curing satisfactory equalization of the images ; the light of 
 Sirius, for example, being reduced to such perfect equality with 
 that of the comparison stars and @ (7th magnitude) that it was 
 impossible to distinguish the image of Sirius from that of the 
 comparison stars, either by the difference of brilliancy or by the 
 appearance of the disc, when both were viewed near the centre 
 of the square. If the images of the comparison stars differed in 
 magnitude the screen was, as a rule, adjusted so as to reduce 
 the brilliancy of the principal star to the mean brightness of the 
 comparison stars. 
 
 When the observer has completed a " pointing " in the manner 
 described, he reads the scales as already mentioned. 
 
 The " scales " are of silver, attached to the two slides which 
 carry the halves of the object-glass and are divided into 150 
 divisions figured at each tenth division. The microscope views 
 both scales at once and (approximately) when the readings of 
 the scale are identical the optical centres of the segments are in 
 coincidence. If this condition could always be realised, the 
 difference of the readings of the two scales would give directly 
 the distance measured in terms of the scale. 
 
 In practice it is of course necessary to find accurately the 
 difference of the readings when the optical centres are in coin- 
 cidence ; this difference is termed the " Index-error." 
 
 Two turns of the micrometer-screw correspond very nearly 
 with one division of the scale. 
 
IX 
 
 An account of the investigation of the division-errors of the 
 scales is given in Dun Echt publications, Vol. II., pp. 11-51. 
 
 As the object throughout the following series of observations 
 was to determine not the absolute distance of the primary star 
 from its comparison stars but the change of these distances as 
 produced by proper motion and parallax, the same divisions 
 were employed throughout the whole of the observations of the 
 same distance, and no corrections for division- error have been 
 applied except for determining the Runs. 
 
 In reading the scales a pointer marks the centre of the field 
 of view of the microscope, and the division preceding and 
 following the pointer is read on each scale. 
 
 The segments and screen are reversed after each observation, 
 a second pointing is made, and the scales again read. 
 
 The instrument is then set for the position-angle and distance 
 of the second comparison star and directed by the circles to the 
 middle point for the new pair, a pointing made, the scales read, 
 the segments and screen reversed, the stars again pointed and 
 the scales read. 
 
 Thus the distance of each of the two opposite comparison stars 
 is measured once in each of the two opposite positions of the 
 segments, and so also the effect of Index-error is eliminated. 
 But such an observation is not complete, because it is non- 
 symmetrical a progressive change in the relative temperatures 
 of different parts of the instrument may, as a matter of fact 
 frequently does, create a change of scale-value which can only 
 be eliminated by arranging the observations in symmetrical order. 
 Therefore the same observations are repeated in the reverse 
 order, that is to say, if the first pair be made in the order a b> 
 the second pair would be in the order b a. The instrument 
 having been reversed 180 in position-angle similar observations 
 are made in the order abba. To complete the symmetry of 
 the work, care was taken on the following night of observation 
 to arrange the order b a a b. 
 
 The following is a copy of the form in which the observations 
 were entered with the original record as entered by the 
 observer.*

 The times entered are those of the Sidereal Chronometer 
 employed. In the block of " Readings the left-hand column 
 gives the reading of the scale division on the further side of the 
 pointer from the micrometer head, the webs approach the head 
 with increased readings of the head. 
 
 The middle column gives the division which is read on the 
 side of the pointer next the micrometer head, and the right- 
 hand column the micrometer reading on the named division. 
 
 The scale readings increase as the micrometer readings de- 
 crease ; therefore, if we refer the scale readings to the zero of the 
 micrometer, it is clear that were there no index-error, no error 
 of Run, and no error of the micrometer-screw, the true reading 
 for scale A. would be 105 divisions = 210 revolutions -f 1 * 600 
 revolutions. But if we suppose for the moment that the 
 division-errors are insensible, the error of Run on scale A. is 
 603 - 600 = + 003 rev. over two revolutions, or + 0015 per 
 revolution ; because if the pointings were exact, and there were 
 no division-error, both readings should agree or rather should 
 differ exactly 2 rev. But since there are accidental errors of 
 pointing in reading the micrometer scales, it is better to deduce 
 the Run from all the scale readings made in the same complete 
 observation, and this is accordingly done. In the example in 
 question we have the following differences in order : 
 
 Scale A. 
 
 Corr. for 
 Screw-error.*

 * The corrections for screw-error result from a very thorough investigation of the 
 screw made independently by Gill and Elkin, the two results being in close agree- 
 ment :

 where u is th reading of the screw-head, and n the number of revolutions from 0*00.

 Mean correction for Run - + * 0030 per rev. 
 
 Having thus determined the correction for Run for one revo- 
 lution, the corresponding correction is to be applied to the 
 readings. These corrections might be applied only to the 
 reading of the division next the micrometer-head, but in this 
 way some accuracy would be lost. It is more exact to suppose 
 that our point of reference is the middle point between the 
 two divisions, and to shift our reference point in imagination, 
 one revolution farther from the micrometer-head. The 
 reduction is then precisely the same as if we used only one 
 division and a known Run, except that the mean of the readings 
 of the two scales is entered instead of the reading of only one. 
 
 Tables were prepared which give the correction for screw- 
 error applicable to the mean of the readings of the two scales 
 with the argument " lower reading." 
 
 The computation of the distances is then effected as follows : 
 Where the sign of B-A refers only to the sign of the 
 correction for index-error.

 The correction for chronometer error on July 6, derived from 
 comparison with the transit-clock, was +5 '8 m. which applied 
 to the mean of each pair of chronometer times of observation 
 gives the sidereal time for each pair of pointings as printed in 
 the results. 
 
 The refraction is computed, having regard to the readings of 
 the meteorological instruments, for each of these epochs ; and 
 being applied the result is the true observed distance free from 
 index-error. The mean of four such determinations of each 
 pair constitutes a complete observation for parallax. The reader 
 who may desire to verify the refraction corrections has only to 
 take the sum of the two distances marked r, the difference 
 between this sum and the column marked R is tlie refraction. 
 The figures in the column marked R give the distance in semi- 
 revolutions of the micrometer-screw. In computing the effect 
 of proper motion and aberration, and in the deduction of the 
 parallaxes, a semi-revolution (R) of the micrometer-screw has 
 been taken : 
 
 R = 12"-865. 
 
 The mean results of these observations and all details of their 
 subsequent discussion are given in the Memoirs of the Royal 
 Astronomical Society, vol. xlviii., and need not, therefore, be 
 repeated here. The concluded results are : .

 On the publication of these results (loc. cit), I submitted to 
 the Lords Commissioners of the Admiralty a proposal to acquire 
 a new Heliometer, of seven inches aperture, for the observatory 
 to continue the work on stellar parallax thus begun, and to 
 determine the Solar Parallax by observations of Minor Planets. 
 Their Lordships responded favourably to this appeal. The 
 instrument was ordered from Messrs. Repsold and Sohne of 
 
xvii 
 
 Hamburg ID 1884, was completed early in 1887, slightly modified 
 in a few details after inspection by me in Hamburg, and was 
 erected, and at work at the Cape before the end of ths same 
 year. This instrument has in every respect fulfilled the high 
 expectations which I had formed of its powers, and the results 
 already obtained, and which will shortly be published, will, I 
 trust, be found to have amply justified the liberality of the Lords 
 Commissioners of the Admiralty.
