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) * Dun Echt publications, vol. ii. f Memoirs of the R.A.S., vol. xlvi., pp. 1-172. o 12309. Wt. 1124. a 2 701 161 IV 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.

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.* * No. 2 has been selected because there is a misprint in No. 1, vide list of errata.

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.* Scale B. Corr. for Screw-error. r r r r + o*oo3 + O'OOI + o'oo8 + O'OOI '010 ooi ooo *OOI '010 ooo + '007 ooo + '019 ooi *oo8 ooi + '012 *OO2 'oo3 ooi ooo 002 - -oo5 '002 + '012 002 + '002 002 + -on ooi + '004 ooi + -012 on + 'OIO ooi - -009 ooo + 'oo3 ooo - -oo3 ooo -f '010 ooo ooo ooi + 'Oi5 ooi + "019 002 + *OOI ooi -1- 'oiS '002 '001 002 + "017 *002 - -oo3 002 + "013 ooi ooo + '001 Sum + 'ioi + '019 + -o56 f '017 * 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 : r r r r 0*00021 cos u 0*00165 sin u 0'00017 cos 2u + 0*00043 r r sin 2 tt + 0'00097 n-0*00024 n 2 r where u is th reading of the screw-head, and n the number of revolutions from 0*00.

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 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 : . Star. Observer. Parallax. Probable Error.

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.
