The observations, of which a record is contained in this volume, were made at Fort Rae, on the Great Slave Lake, during the 12 months extending from September 1, 1882 to August 31, 1883. Fort Rae formed one of the series of circumpolar positions, occupied in accordance with the scheme proposed by the late Lieut. C. "Weyprecht, for concerted physical observations, to be carried on for at least a full year, at different stations situated around the Poles. The units of measure of the observations, the methods of reduction, the scales for graphical representation of the curves, and the form of publication, were fixed by the International Polar Committee at their meeting at Vienna in April 1884. The expense of the Expedition was defrayed by grants from the British Grovernment, and from the Government of the Dominion of Canada. The management of the undertaking was vested in the Royal Society, and by the Society was entrusted to a Committee consisting of the following Fellows : — The President ^ The Treasurer ^ex-officio The Secretaries J John Rae, M.D. Admiral Sir G. H. Richards. Robert H. Scott. The discussion of the magnetic observations has been carried out by myself, with the assistance of Mr. G. M. Whipple, of Kew Observatory. The meteorological discussions have been entirely carried out by Mr. R. Sti'achan and Mr. John A. Curtis of the Meteorological Office. (Signed) H. P. Dawson, March 1886. Captain, R.A. vn INTRODUCTION. Fort Rae is one of the posts of the Hudson's Bay Company. It is situated in Lat. 62° 38' 52" N., and Long. 115° 43' 50" W. on a bay on the northern shore of the Great Slave Lake, and was selected for occupation as being the most northerly of the Company's posts, from which return would be possible, after the termination of the observations, before the closing of the rivers. Had Fort Simpson been the station selected, the observers mio-ht not improbably have been compelled to spend two winters at their post, as the route for reti;rn might not have been open till the summer of 1884. Fort Rae is the nearest of all the Company's stations to the Magnetic Pole, and it presents another advantage of a very practical nature. Provisions at the post are usually plentiful, and this is by no means the case in all parts of the country. To have taken a year's full supplies for the party would have materially increased the cost and diflBculty of transport. It should here be stated that it is mainly owing to the interest taken in the undertaking by the Company's Directors in London, and to the co-operation cordially rendered by their officers in Canada that the Expedition was able to carry its appointed task to completion. The Expedition also received material assistance, in the way of free transport of baggage, from the following railroad and steamboat companies : — The London and North-western Railway, the Grand Trunk Railway, and the Allan Line of Royal Mail Steamers. It was not until the 3rd of April 1882 that the sanction of the Government was definitely obtained. It was at once decided that the organization should be military. Captain Henry P. Dawson, of the Royal Artillery, was appointed to command the party ; the observers were Serjeant J. English and Serjeant F. Cooksley, both of the Royal Horse Artillery, with Gunner C. Wedenby, of the Royal Artillery, as artificer. From the time of departure of the Expedition until its return, the conduct and discipline of these men was all that could be desired. They took great interest in the observations, and did their best to carry them out with accuracy and punctuality. They were always contented and cheerful, in spite of the inevitable discomforts of their winter quarters, and the occasional hardships of the journey. The following was the equipment provided Instruments : 2 mercurial barometers, Kew pat- tern (marine). 2 aneroid barometers. 2 cup-and-dial anemometers (small size). 4 minimum thermometers. 2 minimum (terrestrial radiation) thermometers. 2 hair hygrometers. 2 tubes for earth thermometers. 1 zinc thermometer screen (Wild's pattern). 10 mercurial thermometers. : 1 unifilar magnetometer. 1 rain gauge 'O' 7 spirit „ 2 bifilar „ 2 maximum ., 2 declinometers. 2 ,, (solar radiation) ther- 1 Lloyd's balance magnetometer, mometers. 1 dip circle. vin INTRODUCTION. > Lent by Royal Geographical Society.

Oil 10 gals. use in case of sickness ; and raisins, curry The following supplies were received at Fort Rae : — 2,300 lbs. fresh meat. 780 lbs. dried meat. 190 lbs. grease. 45 lbs. pemmican, for return journey. In addition to fish, ducks, geese, &c. Some of the above provisions were required for Indians in the employ of the Expedition. A small quantity of beads, needles, pocket knives, handkerchiefs, &c. were taken for barter with Indians, but flour, matches, tea, sugar, and tobacco were found to be quite as acceptable. Most of the above stores were, by the kindness of the Hudson's Bay officers, supplied at Winnipeg. Everything was strongly packed in cases, the weight of each package not exceeding 90 lbs. for convenience of handling at portages. The total weight of baggage instruments and provisions, on leaving Winnipeg, was between three and four tons. The above supply of provisions was found to be quite sufficient, in fact the 300 lbs. of bacon were kept as a reserve and were never used at all. It would, however, be unwise for a future expedition of similar strength to take less than the quantities above given. INTRODUCTION. IX Trusting to the country for supplies is not without risk, as in feome years provisions are very scarce, and instances of starvation are not unknown at the Hudson's Bay Company's posts. The time available for preparation (not quite six weeks) was so short that it was not possible to have any instruments specially made for the Expedition, all that could be done was to select the most suitable of those that were in stock at Kew and at the Meteoroloo-ical Office. The Expedition sailed from Liverpool on the 11th May for Quebec, and travelled thence via Winnipeg to Carlton on the Saskatchewan. At Carlton it took leave of civilisation and travelled northwards, for the most part by boat, for two months, I'eaching Port Rae on the 30th August. This latter part of the journey was not so trying to the instruments as might have been supposed, as at the portages (where owing to rapids the boats have to be carried overland) it was possible to see that cases containing fragile instruments were treated with care, but when travelling by rail they could not always be protected from rough usage at the hands of railway employes. Transport in springless bullock carts over exceedingly rough roads also exposed the instruments to many unavoidable concussions. On the Great Slave Lake, the crossing of which, owing to stormy weather, occupied eight days, the boat was stove in, and sunk in a gale ; some of the provisions were damaged and destroyed, and most of the cases of instruments were submerged. Longitude WtST Crecnwich, GREAT SL LAKE AVE A 17420. Fig. 1. Map of part of the G-reat Slave Lake. X INTRODUCTION. An arm of this lake, at first broad, lint afterwards contracting in places to a width of a few miles, extends in a nortli-westerly direction for about a hundred miles (Fig. 1, p ix.) It is continued by a chain of lakes for a long distance in the direction of Great Bear Lake ; in fact, a canoe meets with but few interruptions in passing from one lake to the other. This gulf appears to be the boundary between two different geological formations. To the south- west h a limestone tableland, elevated some 300 feet above the level of the lake, and extending to the Mackenzie River. At a short distance from the lake this tableland ends abruptly, and at the foot of the cliff a former beach of the lake is seen. This beach is now 20 or 30 feet above the present level of the lake, which appears to be gradually falling. On the north-east side of the gulf a plain only slightly elevated above the lake extends as far as the eye can reach. Granite hills rise here and there like islands from the plain, which evidently, at no very distant date, formed a part of the bottom of the lake. The surface is generally a fine white sand, sometimes rock (quartz or granite, rounded by the action of ice) and sometimes " muskeg " or swamp. Beyond this, at a distance of Q. 3 IN.TQ I MILE. ENVIRONS OF FORT RAE. ^h^^^Xff^. INTRODUCTION. xi 30 miles or so to tlio uortli and east the " barren lands " begin : a rocky country, destitute of trees, though not of vegetation, extending to the coast of the Arctic ocean. This is the home of the musk ox and the reindeer. It is the great hunting ground of the Indians and the source of the food supply of the district. Nearer the lake the country is covered with birch, willow, and pine, as a rule small and stunted, though in sheltered places the last-named trees sometimes attain a fair size. The peninsula of Nu-chie (the mountain island) as the Indians call it, projects from the north-east shore, and is the only locality where limestone appears on that side of the bay. It is almost an island, being only joined to the mainland by a small patch of swamp, and consists of a crescent-shaped hill of the height of about 220 feet, precipitous on the outside and sloping more gently to the lake on the inside (Fig. 2, p. x). At the south-west extremity of this peninsula, at the foot of the hill, is a small extent of level ground. Here is the Hudson's Bay Company's post cf Fort Rae, some half dozen log huts, with a large store for provisions, furs, and goods, for trading with the Indians. The lake at this place is shallow, and there is a constant current from the north-west, caused by two rivers that enter the head of the gulf. The gulf contains numerous islands, especially along the north-east shore. It was 10 p.m. on the 30th August when Fort Rae was reached. The 31st was occupied in unpacking the instruments and stores. The barometer, an anemometer, and the thermometer screen, with wet and dry bulb thermometers, were at once placed in position so as to enable observations to be commenced at midnight. There was most fortunately at the spot an un- finished and unoccupied building, admitting of conversion into a Magnetic Observatory. It was a log hut, built for a store, and a door and windows having been put in, a floor laid down and a fireplace built, it answered its purpose very well. The instruments, on the whole, had suffered little from the journey, one of the barometers and two thermometers were broken, a few screws had shaken loose from some of the magnetic instruments, and a mirror required to be re-silvered. These and other similar small repairs were executed whilst the Observatory was Ijeing prepared for their reception, and on the 3rd Septemlier the declinometer, on the 4th the bifilar. and on the 6th the balance magnetometer, were mounted in their places, and observations commenced therewith. The performance of the magnetic instruments was satisfactory, with the exception of the balance magnetometer, as mentioned hereafter, p. 119. Metallic suspension would have been preferable to silk for the bifilar magnet. These instruments were mounted on wooden pillars, sunk to a depth of more than three feet in the ground. Stone pillars would have been better for the purpose, but the only stone available would have required so much cutting that even had the necessary tools been at hand, so much time would have been consumed in the preparation of the pillars that the observations could not have been commenced until late in September. The latitude, longitude, and time were all determined with the transit theodolite. The longitude adopted is deduced from 10 observations of moon-culminating stars, the latitude from the prime vertical transit of a Ursse Majoris. The observations were timed by a chronometer watch Avhose going was frequently checked by the transit instrument, and its rate was found to vary but little throughout the year. The hourly observations were commenced at midnight on the 31st August, the hours were thus divided between the three observers : — A. was on duty from 6h. 30m. a.m. tc 6h. 30m. p.m., A 17420. • C Xll INTRODUCTION. B from 6h. 30m. to lOli. 30m. p.m., C from lOh. 30m. p.m. to 2h. 30m. a.m., A from 2h. 30m. to 6h. 30m.' a.m., and so on. The term days were the 1st and 15th of each month ; on these days the magnetic instruments were read every five minutes, and in addition the declinometer was read every 20 seconds, for a selected hour. The Magnetic Observatory was finished about the 14th September, and a new building for absolute magnetic observations was commenced and completed by the middle of October.

Arch. V. Patches, or undefined light. II. Streamers. VI. Dark segment. III. Stri^. YII. Polar light. IV. Corona. VIII. Sheaves. The brilliancy is shown by Arabic numerals on the scale 1 — 4, 1 being very faint, and 4 very bright, aurora. The letter A denotes that aurora was observed, but that it was more or less concealed by clouds. At hours when no aurora was recorded the state of the sky is shown by the letters b, c, 0. The dotted lines mark the beginning and end of twilight. 109 Port Rae. P.M. August 1883. 9 10 11 Midnight. Sums. 0 0 0 0 o o 0 0 o o c 0 o I. I I b b V. 2 b I o 0 0 o 2 c I. 3 II. V. 2 0 2 c I. II.

MAGNETICAL OBSERVATIONS. 118 MAGNETIC OBSERVATIONS. The Observations made on Terrestrial Magnetism were of two kinds, Absolute and Variation or Differential. ABSOLUTE OBSERVATIONS AND ADJUSTMENTS. The observatoi'j in which the absolute observations were made was a log hnt about 15 ft. (4'5 m.) X 8 ft. (2-5 m.) with a mud fireplace in one corner. No iron was used in its construction. Absolute observations were made in the neighbourhood of the observatory with satisfactory results, no sign of any local magnetic influence being observed. Horizontal Intensity (X). The absolute value of the horizontal component of the Earth's magnetic force was found by means of vibrations and deflections with the unifilar magnetometer No. 102, by Jones, London. During every observation the bifilar was read at short intervals, and the mean of these readings was assumed to correspond with the value of the horizontal force X found by means of the absolute observation. The following are the instrumental constants of the unifilar which were ascertained at Kew before its departure, and verified on the return of the instrument.

The mean of the values of X from the last column of table 1 is * 076604, which corresponds to 420 of the bifilar scale ; when the bifilar readings are corrected by Table 2, this mean becomes • 076577. 120 ABSOLUTE OBSERVATIONS AND ADJUSTMENTS. The bifilar scale reading 400 was accordingly assumed to be = • 076200, and with the scale value found from deflections as mentioned below, p. 124, table 3 was compu ted for the reduction of the variation observations. It appears from Table 1 that the value of on regularly decreased throughout the year, an assumption a priori probable, as the magnet was kept at a fairly even temperature, and never received any shock or blow. In order to utilise observations of vibration unaccompanied by au observation of deflection, and vice versa, so as to compare the observations with one another, and with the corresponding bifilar readings, the value of m was assumed to diminish uniformly, and the amount t (3 m) of the diminution after a time t, was obtained from the observed values of m, each value yielding an equation of condition, of the form m = M — / (o m). The probable values of M and o m having been found from these equations, a value of m was computed for every day on which an observation was made, and from it a value of X. derived. These values being reduced to the standard bifilar reading, the mean of 23 vibration observations was found to be • 076599, and of 19 observations of deflection -076621. Giving half weight to the deflection observations, on account of their greater liability to error, the mean amounts to • 076606. "When the corrections from Table 2 are applied to the bifilar readings, this mean becomes •076578, thus agreeing very closely with the value found above. The probable error of a single observation of vibration is • 000052, and of an observation of deflection • 00008. Table 3. Corrected Scale Keadincr. Absolute Horizontal Force, C.G.S.

Observations for absolute declination were made with the above-mentioned unifilar, the declinometer being read simultaneously. Each observation consisted of three or more readings of the collimator magnet with its "scale erect;" it was then turned 180° on its axis, and a like number of readings taken with the " scale inverted." The torsion was always removed from the suspension thread before commencing observations. The astronomical meridian was determined by star observations with the transit theodolite to within a few seconds, and then indicated by fixed marks both north and south. As the same pillar was used both for the transit instrument and the unifilar, the observed magnetic declination could be referred directly to the meridian. The following table gives the results of these observations, the readings being reduced to the declinometer scale reading 330. absolute observations and adjustments. Table 4. 121 Date.

Magnetic disturbance was observed to be in progress during these observations. A 17420. 122 ABSOLUTE OBSERVATIONS AND ADJUSTMENTS. The observations indicated tliat tlie zero value of the declinometer scale began to change slowly in April, and continued to move in the same direction until July. This was probably due to a movement of rotation in the wooden pillar caused by absorption of moisture in the spring. I noticed a movement in the same direction with the transit instrument, which, when directed to a fixed mark on one day, was often found on the following day to be pointing two or more minutes to the eastward of it. Inclination. Tor observations of inclination a dip circle by Barrow, London, with 3^-inch (9 cms.) needles was used. Table 5 gives the results of these observations. At every observation both ends of the needle were read in each of the usual four positions ; the poles were then reversed and the readings repeated. When the inclination was observed at Kew with this instrument, before leaving England, an almost identical value was afforded by needles 1 and 2, and no difference in the results obtained from them was observed at Fort Rae. The instrument was so much injured on its journey back that it was not possible to make any observations with it after its return to Kew. An inspection of the observations showed that the value of the inclination varied at different times of the day, and they were accordingly grouped by hours with the following results. Table 6.

It corroborates the fact of the great diurnal variation of the inclination, and the mean value for the month or year will probably be more accurately found from the mean values of the vertical and horizontal forces than from the observations of inclination, which are too few in number and are not fairly distributed over the 24 hours. ABSOLUTE OBSERVATIONS AND ADJUSTMENTS. 123 Vertical Intensity (Y"). The absolute value of the vertical component of the Earth's magnetic force Y corresponding to a given reading of the balance magnetometer, was found from each value of the inclina- tion 5, in conjunction with the corresponding value of the horizontal intensity X by the formula, Y = X tan. 9. These 61 values of Y were reduced to the same scale reading of the balance magnetometer ; five of them were rejected by Pierce's criterion, and the mean of the remainder, 0 • 6176, was adopted as corresponding to the scale reading 1500, and with the scale value found below. Table 11 was computed for the reduction of the variation observations. The probable error of this mean was found to be • 0004. VARIATION OBSERVATIONS. The observatory for the variation instruments was a log hut, 19 ft. 9 in. (6 m.) X 16 ft. 6 in. (5 m.), and from 7 ft. 6 in. (2-5 m.) to 15 ft. (4-5 m.) in height. The floor was fastened with wooden pegs, the windows with copper nails. The walls were of wood and mud, the fireplace of mud and stone, which latter had no effect on the magnets. The projection of the fireplace on either side screened the balance magnetometer and declinometer from the direct heat rays of the fire ; the bifilar was screened by a table, which was nailed to the floor. The accompanying plan shows these details and the ^Josition and distance apart of the diff'erent instruments, which were mounted on wooden pillars about 0'2 metre in diameter, sunk about 1 m. in the ground.

A transportable Weber magne- tometer with 3-inch (7 cm.) needle, hung in a loop of unspun silk fibre, was adjusted by placing the instrument with the telescope to the North, and in the magnetic meridian, the interval between the suspending threads being so regulated that when the torsion circle was turned through 138°, the reflection of the centre division of the scale coincided with the cross wire of the telescope. Although it was found that the instrument thus adjusted was slightly too sensitive, it was thought best to leave it untouched, rather than to break the continuity of the observations by altering the adjustment. Q 2 124 ABSOLUTE OBSERVATIONS AXD ADJUSTMENTS. The following deflections of the bifilar magnet with the unifilar magnet (N 5) were observed for the determination of the scale value of the instrument.

Declinometer. The declinometer, one on Lamont's principle, having a cylindrical magnet 2 '5 in (6 cm.) in length was adjusted by suspending the magnet by a bundle of unspun silk fibi'es and (after the instrument had been levelled and the torsion removed from the suspension thread) bringing the reflection of the central division of the scale into coincidence with the cross wire of the telescope. Each division of the scale was = 60" • 6, and since of the coefficient of torsion ^^ varied from • 00266 to • 0044, the value of one scale division ranged between 60" • 76 and 60" • 87. In the reduction of these observations the scale divisions have been taken as minutes ; the recorded deviations are therefore too small by about 1'3 per cent. Once finally adjusted, this instrument, like the bifilar, was left untouched until dismounted on the morning of the 1st September 1883. Balance Magnetometer. The instrument for observing the variations of vertical intensity was a Lloyd's balance magnetometer with 12-inch (30 cm.) magnet. It was adjusted by levelling the base slab and bringing the magnet into the plane of the magnetic meridian. It was soon found that the magnet was largely afi'ected by changes of declination, and required continual re-adjustment to bring it back into the meridian. The slow oscillation of this long magnet was a frequent source of error in reading off' its scale. The scale value was determined from the times of vibration of the magnet observed both in the vertical and horizontal planes, which were 16 (/') and 10 (t) seconds respectively. The value of the ratio -^ was therefore 2*56, and the resulting value of one division of the scale "0000093 Y. ABSOLUTE OBSERVATIONS AND ADJUSTMENTS. 125 The variation instruments were read at each hour of local mean time in the order, bifilar, declinometer, balance magnetometer, at one minute before each hour, at the hour, and at one minute past, until the 11th October 1882, but on and after that date the readings were made at two minutes' interval, i.e., at 58m., 0., 2m., as it was found that with only one minute's interval between the reading there was a certain amount of huiTy, and consequent liability to error, in recording the observations. The bifilar was read at the exact second, the declinometer 12 seconds later, and the balance magnetometer 40 seconds after each minute, but this latter instrument took more or less time to read according to the distance it was necessary to move the micrometer screw to obtain a correct setting. On days of disturbance observations wore also made at the Gottingen hours in the same manner. NOTES ON THE REDUCTION of the DIFFERENTIAL or VARIATION OBSERVA- TIONS ; BY G-. M. WHIPPLE, B.SC, Superintendent of the KEW OBSERVATORY. During the period of observation at Fort Rae all the diffei'ential or variation instruments were read three times at each hour, two minutes being allowed to elapse between the consecutive readings, and the mean of the three readings has been accepted throughout as the true value for the hour. This does not, however, obtain on term days when the tri-horary readings were not made, but the actual reading at the instant of the hour was only taken. The observations were all entered according to local time, care being exercised on term days to correct the readings for difference in time when transcribing them from the term day to the ordinary observation book. Declination. The values used in the reductions are given in the following table, one scale division of the declinometer being assumed to be equal to 60" of arc. {See p. 124.) Table 8. Date.

No calculation of means or difi'erences have been made from them. HORIZONTAL INTENSITY (BIFILAR MAGNETOMETER). {See p. 123.) The scale value of this instrument and the temperature corrections of its magnet were determined at Kew, and the latter was also re-examined on its return, but the corrections so found were seen, by a preliminary reduction of the readings, to be very inadequate for the purpose of reducing the observations made when the instrument was fixed in situ, and measures were taken to deduce the true corrections from the observations themselves. The first step in the reductions was to find the mean scale reading for the hour from the three observations, as in the case of the declination. These values were then extracted for the hours of 11 a.m., noon, and 1 p.m. (being the period of least variation) on such days as the magnets were fairly steady, with the ABSOLUTE OBSERVATIONS AND ADJUSTMENTS. 127 corresponding observed temperatures ranging from about — 15° to + 25° cent. From these the mean values for every change of 10° was computed, and corrected for change of zero of the instrument. The observations as corrected by this preliminary determination of the temperature effect were plotted in a curve, and irregular readings being then rejected, a new value was found. In this way a final temperature correction was arbitrarily determined, and the values given below adopted for the reduction of the observations to a common temperature. Table 9. Temperature. Cent.

Similarly daily, hourly, and monthly means have been computed, and the maximum, minimum, and diurnal range calculated. TEEM DAY OBSERVATIONS. The values of the horizontal intensity have been computed for every five minutes on the term days already referred to, and plotted as curves. (Plates 1-23.) Term hour observations of this instrument were not made. VERTICAL INTENSITY (LLOYD'S BALANCE MAGNETOMETER). The instrumental readings as recorded are those of a micrometer placed opposite the South end of the magnet, and are such that one division represents a change of "00001 C.G-.S. units of force, but on account of the instrumental defects already enumerated, p. 124, the last figure has not been taken into account. The reductions and values are thus only given to •0001 C.G.S. The first step in the reductions was to make a preliminary determination of the temperature correction ; this was done in the same manner as for the bifilar by ascertaining the change in the scale readings when temperature altered greatly, — but corresponding readings of the other instruments showed a comparative absence of magnetic disturbance, — the value so found was roughly calculated to be ± 6-5 divisions for ± 1° centigrade. B.aving constructed a table from this value the hourly readings for each day were reduced to the mean temperature of the day, and the daily means for both scale readings and temperature computed. Next, the change in readings produced by each re-adjustment of the instrument was estimated both by comparison of readings before and after such re-adjustment, which values 128 ABSOLUTE OBSERVATIONS AND ADJUSTMENTS. ■were generally noted in tlie journal, and also by comparison of daily means for adjacent days at tte time of the adjustment. The values finally adopted were as follows : — Table 10. Corrections for change of zero produced by lifting of the Magnet of the Balance Magnetometer. Date. Scale Divisions. Date Scale Divisions.

These corrections being applied to the daily means, 5-day averages of both scale readings and temperature were calculated and the results plotted in a curve ; measurements were then made from this curve and a final temperature correction of ^ 1° centigrade = ±4*5 scale divisions found. The 5-day means and their corresponding temperatures were then again copied and the new temperature correction applied ; another plotting of the second set of 5-day means was then performed and the smoothing of this curve afforded materials for a better estimation of the effects of the re-adjustment of the magnet. Finally a table was drawn up giving corrections to be applied to the daily readings of the magnetometer so as to bring them into one uniform continuous series. The means of the tri-horary readings were then taken, copied out, reduced to temperature 0°, and corrected for adjustment. The same reductions were also applied to term day readings. A selection was then made of corrected and reduced scale readings for the times at which absolute determination of the vertical force had been computed by Captain Dawson from his unifilar and dip observations, and from these the following table was prepared for converting scale readings into absolute units.

Daily, hourly, and monthly averages were then finally computed. The readings on term days were merely copied into the Schedules after correction and reduction, and plotted as curves. (Plates 1 to 23.) OBSERVATIONS ON SELECTED DAYS. In conformity with the decision of the Vienna Conference, the instrumental readings on certain days enumerated by Dr. Wild have been copied out, reduced, and measured, in order to give the undisturbed diurnal variation of the magnetic elements. These observations have been entered according to Gottingen mean time, although they were not made precisely at the Gottingen hours, excepting in the case of term days. The rule followed throughout has been to enter observations at Ih., 2h., 3h., a.m., &c., Fort Rae mean time as 9h. 23m., lOh. 23m., llh. 23., a.m., &c., Gottingen mean time. These observations have been grouped in pairs of months in compliance with Circular No. 39 issued by Dr. Wild, and the final curves of diurnal variation drawn from them. (Plates 29 to 32.) Table 12 exhibits the average values of the Horizontal, Vertical, and Total intensities as well as the Inclination and Declination at Fort Rae, for the year 1882-83, as derived from the means of these selected days.

General Remarks. The aurora was observed hourly, after the magnetic and meteorological observations had been made ; i.e. at from five to ten minutes after each hour. No means were available for the instrumental determination of the altitude, &c., of arches ; the information given on these points is by estimation. The bearings given are true, not magnetic. The situation of the Observatory was not altogether favourable for auroral ol)servations high ground from north to east hiding the horizon to an altitude of 3° or 4° in the direction of the magnetic north. In other directions the view was uninterrupted. The brightness is expressed by numerals on the scale 0 to 4. • 5 is rather brighter than the Milky Way. 4 is bright enough to see to read by. The general colour of the aurora was greenish-yellow, not unlike moonlight, showing in the spectroscope a single line between the green and the yellow. This line was often visible on overcaBt nights, or when the spectroscope was turned to parts of the sky where no aurora was to be seen. When the brightness reached 1"5, jorismatic colouring frequently showed itself, the lower edge of the arch generally assuming a violet or mauve colour, the upper edge retaining its yellow colour, which however looked at times almost green, pi^obably by contrast. On these occasions a faint continuous spectrum and several bright lines appeared towards the violet end of the spectrum. I once saw a bright band in the red. It sometimes happened, however, that towards the end of a brillant display of aurora a crimson glow seemed to fill the air below the arch, of which it did not appear to form a part. This colour was very rich and beautiful, and quite different from the colouring of the aurora itself. On the few occasions on which aurora was seen by daylight {i.e. after sunset, but before the stars had begun to be visible) it appeared of a pinkish, salmon, or copper colour. The type of the aurora, and time of its appearance, was generally much the same on successive nights. The displays were as a lule unattended by the slightest sound, but that a peculiar and distinct sound does occcasionally accompany certain displays of aurora, there can be no doubt. The Indians, and voyageurs of the Hudson's Bay Company, who often pass their nights in the open, say that it is not uncommon ; a European who lives in a house may pass a lifetime in the country without hearing it. On one occasion I was fortunate enough to hear it myself. The sound was like the swishing of a whip, or the noise produced by a sharp squall of wind in the upper rigging of a ship, and as the aurora brightened and faded, so did the sound which accompanied it. This proves that the aurora could not have been distant, and I think it possible that these low aurorte may be of a different nature to the high ones. 17420. 254 Gcittingen Mean Time.
