The Magnetical Observatory is situate nearly on the summit of a ridge, which occupies the left or northern bank of the Tweed, being 540 feet distant from, and 80 feet above, that river. The Astronomical Observatory is upon the highest part of the ridge, 140 feet due west of the Magnetic Observatory. A fair horizon is seen from the Observatory hill, being bounded about 10 miles to the east by a slightly- swelling ground, which, to the east-south-east, seems to join the Cheviot Hills. The view is bounded about a mile to south and south-west by a ridge, forming the right bank of the Tweed; about 500 feet to the south-west and north-west by masses of trees in the Makerstoun grounds ;§ and from 1 to 3 miles to north-west, north, and * Ast, Nach., vol. x., p. 214. + Deduced from the longitude of the Astronomical Observatory, Mem.

From north, by the east, to the south, the elevation of the horizon, with a slight exception, is under 2°; from the north to the north-west, increasing from 2° to 4°; from the north-west to the south-west, the tops of the trees are elevated from 5° to 8°; and from the south-west to the south the eleva- tion is under 4°. The highest point of the Cheviots, which is 2656 feet above the level of the sea, is about 18 miles to the east-south-east ; it is occasionally referred to in the meteorological remarks on clouds. 3. The Observatory hill, it is believed, is composed of felspathic trap. The Tweed, immediately to the south, and for a mile to the east and west, flows more or less through this rock, which does not appear upon any part of the hill. The opening for a foundation to the Observatory shewed only masses of rolled pebbles, and boulders of greywacke and trap. 4. The Observatory is rectangular in its plan, 40 feet by 20 feet internally. It is formed of wood ; copper nails were used ; and iron carefully excluded from every part of the structure. The pillars for the magnetometers and telescopes are of stone, from 22 inches to 19 inches in diameter, and are placed upon excellent stone foundations, completely unconnected with the floor, and every part of the building. By a reference to the plan and elevation, the following details will be understood. (Plate I.) There are two windows to the south, with the door between ; and three to the north, which open like folding doors. The dimensions of the principal apartment are, 40 feet long, 12 feet broad, and 12 feet high. The two ante-rooms are each 15 feet long, 74 feet broad, and 12 feet high. The instruments are indicated in the plan as follow :—D, the Declinometer, ¢, its Reading Telescope; A, the Azimuth Circle and Transit; H, the Bifilar or Horizontal Force Magnetometer, t’, its Read- ing Telescope, P, a Pillar for a Collimator (not used); V, the Balance or Vertical Force Magnetometer ; I, Pillar for the Inclinometer (not used here); B, the Stand- ard Barometer ; W, the Anemometer; W’, the Wind-Vane Dial-Plate; T, the Thermometer Case; C, the Mean Time Clock; S, the Copper Stove (removed Nov. 44 23", 1844); ns, the Astronomical Meridian ; D ¢, the Magnetical Meridian. The vane farthest to the right in the elevation, Plate I., belongs to the anemometer ; the others give the direction of the wind. SYSTEM OF OBSERVATION, AND STAFF OF OBSERVERS. 5. In the beginning of 1843, the number of daily observations was increased to nine, at two-hourly intervals, commencing with 18" Gottingen mean time (5° 10™ a.m. Makerstoun mean time); these, together with all the other daily observations, were made by Mr WetsH and myself. In the end of 1843, I recommended to Sir THomas BRISBANE to add Mr ALEXANDER Hoce, who had been previously employed in the term-day observations, to the establishment, for the purpose of obtaining a complete DECLINOMETER. Xl diurnal series of observations. Sir Tuomas, with his usual anxiety to render the Observatory in every respect useful to science, at once complied with my recom- mendation ; and, in the beginning of the year 1844, hourly observations were com- menced, which were continued till the end of the year 1845. The whole staff of observers, after the commencement of 1844, therefore, consisted of Mr Joon WELSH, Mr ALEXANDER Hoae, and myself; Mr Dons assisting in the term-day observa- tions, and on a few occasions during disturbances. DECLINOMETER. 6. The declination magnetometer was obtained from Gruss of Dublin. The magnet a is 15 inches long, § inch broad, and 4 inch thick ; it fits into a stirrup 6, whose two eyes receive an axle to which the suspension thread is attached ; near the north extremity it carries a scale divided on glass, c; near the other, at a dis- tance from the scale of about 12 inches, the focal length, it carries a lens of 14 inch diameter, d. A marble slab m, cemented to the top of the stone pillar p, carries two copper tubes ff, 35 inches long, which are connected at the top by a mahogany tie g, bearing the torsion-circle and suspension apparatus ¢, and, about 7 inches Xi INTRODUCTION TO THE MAKERSTOUN OBSERVATIONS, 1844. from the slab, by another wooden cross-piece h, which supports a glass tube ¢ enclos- ing the suspension thread. The magnet is enclosed by a rectangular wooden box &, formed of two pieces fitting into each other in the middle by a groove and tongue, glazed at the extremities, and having only a small aperture in the centre for the suspension thread: this box also enclosed a copper ring for checking the vibrations of the magnet; it was removed October 15, 1844, and is not shewn in the figure : a cylindrical wooden drum 2, together with two lids (not shewn in the figure), fitting by pegs upon the cross-piece h, enclose the box and magnet. There are two glazed apertures also in the wooden drum, opposite those in the rectangular box ; one to the north, where a small mirror / throws light upon the glass scale; the other to the south, between the lens and reading telescope. All the joints of the boxes, including those in contact with the marble slab, are covered with velvet, and both boxes are pressed firmly against the marble slab by means of leaden weights, which were pre- viously determined to have no effect upon the position of the magnet. In order to destroy any effect of radiation, both boxes were covered with gilt paper, externally and internally. The suspension apparatus is covered by a wooden cap (not shewn in the figure). In order to prevent the variation of humidity within the boxes as much as possible, the whole apparatus was covered, February 14, 1844, by a thick double cotton hood, tied round the stone pillar, and having only small openings at the glazed apertures of the boxes. The reading telescope is fixed to a stone pillar ; the object glass is 8 feet to the magnetic south of the magnet lens. 7. The pillar of the azimuth circle, used for determinations of the absolute declination, is between the pillars of the magnetometer and its reading telescope. This theodolite is by TRouGHToN; the circle is 15 inches in diameter, is divided to 5 minutes, and is read to 5 seconds with three verniers. The lines of collimation of the theodolite and reading telescopes coincide when the middle wire of the former is seen, in either telescope, coinciding with the vertical wire of the latter. The circle is retained in the same position on its pillar, but the transit telescope is re- moved, excepting when required for observations of absolute declination. 8. The following are the data used in reducing the observations of the decli- nometer :— Values of the declinometer scale divisions in angular measure. The adopted mean value of one division of the long scale of 500 divisions = 0:6725* During the observations of absolute horizontal intensity, the magnet with the long scale, usually in the declination box, was removed to the unifilar box in the intensity house, and a magnet with a short scale was substituted. The adopted mean value of one division of the short scale of 300 divisions = 0’-7500* * For details, see Introduction to the Observations for 18438, pp. xiii. and xiv. DECLINOMETER. Xl From the adopted values of the long and short scale divisions, the coefficient for reducing the divisions of the short scale to the same value as the divisions of the long scale = 1:115 ; the reciprocal = 0-897.

Reasoning as in the previous case, 2 A X may be supposed nearly zero, and the last member of the equation negligible. If, however, the supposition that the sign of 4 X varies positively and negatively with reference to the sign of A t be inaccurate, it must be supposed either that the horizontal component remains * If the scale readings increase with increasing horizontal force, A R will generally be negative when A ¢ is positive, and vice versa. The sign of A ¢is used as the argument, so that if A R be positive when A ¢ is positive, that value of A R will be subtracted from the sum of differences 3 A R. xlvii INTRODUCTION TO THE MAKERSTOUN OBSERVATIONS, 1844. constant, and therefore, that 4 X =0, or that it varies in one direction only, in- creasing continuously, or diminishing continuously, throughout the period selected, and, therefore, that the sign of A X is the same for both equations. In the latter case, it is evident that by taking the mean of the values of q’ from the two equations, the last members will nearly destroy each other. It has been supposed that the variations of X are altogether independent of the variations of the temperature, a supposition which is borne out by every method of examination of the results. The details of aseries of comparisons are given, pages li., lii., and lii., Introduction, 1843, from these it appears : 70. 1st, That the value of g’ is the same, when a sufficient number of compari- sons have been obtained, whether it has been obtained from comparisons of daily means, at 1, or 2, or 3, . . . . or 14 days’ interval. 71. 2d, That the value of q’ is the same, whether the differences of temperature have been due to natural or artificial causes, and when the differences of temperature of the magnet have had an opposite sign from those for the temperature of the ex- ternal air. 72. From the second result, it follows, that the variations of the horizontal component of the earth’s magnetism are wholly independent of the temperature of the air, and from both results it appears probable that they are independent of the temperature of the soil.* 73. The following Table contains the sums of differences of the daily mean temperature of the bifilar magnet, and the value of ¢ which has resulted from each series of comparisons. The series of comparisons for 1845 have been made since the publication of the series for 1844, for the purpose of verifying the constancy of the result.

The value of one scale division in parts of force for the period of comparisons (1844 and 1845), being & = 0-000140. Whence, the correction for 1° Fahr., from comparisons of observations, is g = 0:000266. 74. The result from hot and cold water experiments is nearly + more. It ap- pears, therefore, that the determination of the temperature coefficient, by removing the magnet from its position in the instrument and varying its temperature by means of hot and cold water, cannot be depended on. It appears also, that when a suffi- cient number of observations is included, the method of comparison previously de- scribed gives, under very different conditions, consistent, and, therefore, it is pro- bable, accurate results.* Balance Magnet. 75, The temperature coefficient of the balance magnet was determined by means of hot and cold water experiments August 24, September 1 and 2, and November 13, 1843, and January 27, 1844. See pages xlii., xlin., and xliv., Introduction, 1841-2, for the details. The mean of the whole observations, properly weighted, gave = 0:000073. 76. The only good series was that obtained January 27, 1844, which included changes of temperature from 35° to 65° only ; the other series are too inaccurate to be employed for the determination of the value of g for high and low temperatures ; from series of comparisons of the usual observations of the balance it has been found, however, that the value of gq’, the temperature correction for 1° Fahr. in mi- crometer divisions, is the same for high and low temperatures, thus— Mic.

As it was found impossible to determine & the value of one micrometer division in parts of the whole vertical component, by means of the vertical vibra- tions, the value of g obtained from hot and cold water experiments could not be em- ployed, since the observations could not be reduced to parts of vertical force, nor could the value of g be reduced to micrometer divisions. In consequence of this difficulty, the method already described for the bifilar magnetometer was first em- ployed for the determination of q’ the temperature coefficient in micrometer divi- sions: the details of several of these comparisons will be found, pages xlv., xlvi., xlvu., xlvui., and xlix., Introduction, 1843. It was found from these comparisons, 1st, That the value of q’, when a sufficient number of comparisons had been obtained, was independent of the interval between the days compared. 2d, That the value of g’ remained the same after various adjustments of the needle ; the vertical screw for adjusting the sensibility never having been touched. 3d, That the value of q’ has remained constant while the time of vibration ina vertical plane has varied from upwards of 11° to less than 6°; from which result it has been concluded that the value of & also has been constant. 4th, That the value of q’ is the same, whether the differences of temperature of the magnet have been due to natural or artificial causes, and whether the differ- ences of temperature of the magnet have had the same sign or an opposite sign from those of the temperature of the air. 78. From the 1st and 4th conclusions, it follows that the variations of the ver- tical component of the earth’s magnetism are independent of the temperature of the air and of the temperature of the soil.* 79. The mean of all the results in the volume for 1843, Introduction, pages xlvi. and xlviii., gave g = 7:90 micrometer divisions ; and adopting the value of k, obtained from deflections, No. 59, q = 0:000079. Which result is only is more than that obtained from the hot and cold water ex- periments : it appears in the case of the Makerstoun instrument that the errors of the usual methods are found chiefly in the determination of & ; this, however, is not always the case. The observations for 1843, 1844, 1845, and 1846, in micrometer divisions, have been corrected by the value * See foot-note, p. 395 of the present volume. TEMPERATURE COEFFICIENT OF THE BALANCE MAGNET. li g = 790 micrometer divisions. 80. Since this value was obtained, several other determinations have been made, by comparisons of observations in 1844, 1845, and 1846 ; all the results obtained are given in the Table below ; several of the results obtained more lately have been de- duced from periods ill fitted to give a good value ; the whole, however, have been given in order to shew the amount of error that may be expected in using bad series. In one or two of these cases the amount of disturbance has not been very consider- able, but the greatest variations of the daily mean vertical force have happened to occur at the same time with the greatest variations of mean temperature ; it is believed that it is to this cause chiefly that the differences of the results are to be attributed.

If the whole series were properly weighted, it is believed that the resulting value of q’ would be less than 8:00 mic. div. The excellent series, November 30—De- cember 26, 1846 (after an adjustment July 1846) gives li INTRODUCTION TO THE MAKERSTOUN OBSERVATIONS, 1844. g = 7°72 mic. div. The adopted value of the temperature coefficient for the balance magnet = 7-90 mic. div. It is believed that this value, which has been used in correcting all the observations since the commencement of 1843, is within one-tenth of a division of the truth. 81. The following matters should be attended to in determining the tempera- ture coefficient by the previous method. 1st, The period selected should be free from considerable magnetic irregularities. 2d, There should be a considerable change of daily mean temperature, the tem- perature at the beginning and end of the period being nearly the same. 3d, The smaller the duration of the period consistently with the 2d the better. 4th, It will be found best, in general, to correct the daily means at first by an approximate coefficient, and 5th, To eliminate the secular change approximately, if it be considerable. Both the latter methods were employed in many of the determinations given in Table 9. INCLINOMETER. 82. The dip instrument was made by the late Mr Roprnson of London. The vertical circle is 93 inches in diameter ; it is divided to 10’, the graduations counting from 0° on the horizontal to 90° on the vertical ; 1’ is estimated with the aid of lenses attached to a glazed case ; the vertical circle turns with a copper framework on a vertical axis, centred in a horizontal circle ; the latter is 6 inches in diameter, is divided to 30’ and is read to 1’ by means of a vernier. A sliding framework carrying Ys moves within that bearing the agate planes on which the axle of the needle rests; the Ys serve to lift and lower the needle on the agates, but they have been found to act very irregularly, at times giving the needle a pitch in a certain lirection. A level screwed to the basement plate indicates the horizontality of the agates ; this was, however, also verified occasionally by means of a small level placed upon them ; it was found that the level varied according as the door of the case inclosing the instrument was shut or open; it was, therefore, always tested with the door shut, as it is during observations. The reading of the horizontal circle, when the vertical circle is in the magnetic meridian, was obtained with the aid of a horizontal needle, carried on a pivot whose arms rest on the agate planes. There are two dipping needles, numbered 1 and 2, and one end of each needle is marked A, the other end is marked B; all the marks are on one face of each needle. The needle is observed in four positions with one end dipping, namely, with the marked face of the needle on the same side as, and opposite to, the graduated face of the circle, the latter being in the meridian, first to the east, and then to the west; as INCLINOMETER. hin each extremity of the needle is observed, there are thus eight readings obtained. The poles being changed, and the other end dipping, other eight readings are similarly obtained. The means of the two readings for each position are given in this volume. In changing the poles, the needle was placed on a small wooden block having a hole to receive the axle; it then received eight strokes on each face (as in the method of double touch) from two magnets, each 9 inches long, 2 inch broad. 83. Observations were made on April 18 and May 2, 1843, in different azi- muths, in order to determine the correction due to the irregularity of the needle’s axle, or perhaps to the presence of iron in the vertical circle; these observations have been already given (Table 21 and Table 22, Introduction, 1841-2.) The cor- rection deduced was about — 11’ for needle No. 1. No correction has been applied to the results in this volume. In 1846, the vertical circle was removed from the instrument and placed horizontally, the dip needle was suspended by a silk fibre within the circle, the needle and circle being in the same plane, the needle was then vibrated horizontally, and the zero of the graduations was placed in different azi- muths ; the time of vibration was found very little affected by the varying positions of the circle; it seems probable, therefore, that the correction above mentioned is due solely to the imperfections of the axle. The inclinometer occupied a strong wooden pillar in the intensity house uncon- nected with the floor. 84. From various instrumental causes, the observations of magnetic dip in 1844 appear to be of little value, the difficulties in connection with the lifter already noticed in the Introduction for 1843 were frequently experienced, much care was bestowed upon the observations, but, without some alteration in the instrument, no care seemed capable of giving consistent results. Upwards of 60 hours were ex- pended in observing alone in 1844, and a half may be added for the necessary pre- parations, &c. Yet, it is conceived, that a single good observation would be as valuable as the mean of the whole.* The observations are given, pages 162-164. The mean of all the observations of magnetic dip in 1844 = 71°28”7. * Observations were made in the following manner for the determination of the magnetic dip in February 1846. The dipping needle having been placed on its supports in the inclinometer, it was deflected by a magnet placed at known distances, in order to determine the ratio of the magnetic moment of the deflecting bar to the vertical component of the earth’s magnetism ; the moment of the bar was obtained from observations of deflection and vibration for the absolute horizontal intensity, whence the vertical component could be determined, and the dip from the ratio of the two com- ponents. The advantage of this method over others, consists in the capability of using a powerful deflecting bar whose moment can be determined with the accuracy of the observaticns for the hori- zontal intensity.

The tube is 0°552 inch in diameter; the scale is attached to a brass rod, terminating in an ivory point, which at each ob- servation is moved by means of an endless screw till it meets its image in the mer- cury of the cistern ; the cistern is about 3 inches in diameter; the vernier professes to read to 0-002 inch, and that 0:001 inch may be estimated, but the graduation is so inexact as to give changes in error from 0-002 to 0-003 inch, when the reading is made alternately at the two extremities of the vernier. 86. In 1841, the barometer was compared indirectly with the standard baro- meters of the Royal Society of London, by means of one made by NEwaN for the DuKeE of ArGYLE. The comparisons of the DUKE of ARGYLE’S barometer with the readings from the flint and crown glass tubes of the Royal Society (both tubes being connected with the same cistern) are given, Table 23, Introduction, 1841-2. They are not consistent. A consistent series of comparisons of the Makerstoun barometer with the DuKE of ARGYLE’S is given, Table 24, Introduction, 1841-2. The results of these comparisons are in.

All the observations of the Makerstoun standard barometer are corrected by—0-012 inch to the mean of the Royal Society’s flint and crown glass barometers ; they are also corrected for temperature to 32° Fahr., by ScaumAcuER’s Tables, given in the Report of the Committee of Physics of the Royal Society of London. The cistern of the barometer is 213 feet above the mean level of the sea at Berwick-upon- Tweed. THERMOMETERS. 89. The dry and wet bulb thermometers aa are by ADIE and Son. The bulbs bb are 0:3 inch in diameter, and tenths of a degree can be estimated with accuracy on the scales aa; the thermometers are attached to a wooden slab ¢, fixed to the lvi INTRODUCTION TO THE MAKERSTOUN ORSERVATIONS, 1844. moveable front d of the wooden case, 4 feet above the soil ; the bulbs project below the wooden slab c, and as holes are cut in the wooden case behind them, they are exposed to freely-circulating air. The wooden case, which has slightly-projecting top and sides at the front, and a double sloping back, revolves on a post f, and can be turned from within the Observatory by means of cords and pulleys g g. When an observation is made, the case is turned till the thermometers face the window h, being 9 inches distant from it ; after reading, which is done through the glass (thus avoiding any error due to proximity of the observer, or the light at night), the case is again turned with the back towards the window, or towards the wind if it rain. It was found early in the summer of 1843, that in spite of the precaution of turning the back of the case towards the sun before 7" A.M. and after 5" p.m., if the sun shined brightly, the temperature indi- cated by the thermometer was visibly increased. In all such cases, therefore, the moveable front d was lifted off the case and suspended in the shade, at an equal height from the soil, on the west or east wall of the Observatory, being kept apart from it by projecting knobs. Observations at different times shewed, that, all other things being equal, the temperature was the same in all the three positions, but when the sun shined on the case, it might be one or two degrees less to the east or west than to the north. The observations made to the east or west after July 9, 1844 are indicated in the column of differences by a cross, thus +, for the first ob- servation after removal from the case, and by a cross, thus |, for the last observation before replacing the thermometers on the case. 90. It sometimes happens, when the air is very humid, during frost, and on clear nights, especially when the temperature is falling, that the dry bulb thermo- meter reads less than the wet bulb ;* when such is the case, the difference of the readings of the two thermometers has not been given, and in the summations for * The cause of this apparent anomaly in frosty nights, it is conceived, is due to the deposition of moisture on the silk cover of the wet bulb, which is frozen as it is deposited, till it becomes a thickish coat of silk and ice; the dry bulb receives, at the same time, a thin coat of moisture, and becomes a more facile wet bulb. In clear, humid nights, without frost, nearly the same explanation will apply; the dry bulb will radiate its heat into space with more facility than the wet bulb. It might be preferable, therefore, on these occasions, to make use of the readings of the wet bulb for the temperature of the air, and of the readings of the dry bulb for the temperature of evaporation during frosty nights; where, however, the differences of the readings may be considered due chiefly to the different radiating powers of the two bulbs, the readings, perhaps, should be considered the same ; this has been done in all cases in the present volume. THERMOMETERS. lvii the abstracts of results, the reading of the wet bulb has been considered the same as that of the dry bulb. 91. The following Table contains the corrections of the dry and wet bulb thermometer readings for 1844, to the reading of a standard thermometer by NEWMAN,—the reading of the latter, in a mixture of pounded ice and water, being 32°00. On January 7, 1843, a series of comparisons of different thermometers was made with the standard thermometer ; the comparisons were made in water of different temperatures; the results were given in the Introduction for 1843, Table 23, p. lvii. On October 17, 1843, the readings of the thermometers in a mixture of pounded ice and water were obtained; they were as follow :— NEWMAND’S standard, 32°:00. Dry bulb, 32°8. Wet bulb, 32°-7. Similar comparisons, September 4, 1844, gave NEWMAN’S standard, 32°00. Dry bulb, 32°75. Wet bulb, 32°65. On January 7, 1843, the readings in water and ice were, NEWMAN’S standard, 32°:00. Dry bulb, 32°-7. Wet bulb, 32°6. It appears, therefore, that in 1844, the index errors of the dry and wet bulb thermometers were about one-tenth of a degree greater than in January 1843; altering the errors, Table 23, Introduction, 1843, to this extent, we obtain the following Table :— TABLE 12.—Corrections of the Dry and Wet Bulb Thermometers to the Tempera- ture by Newman’s Standard, in 1844. Corrections. Corrections. Tempera- Tempera- ture. The observations of the dry and wet bulb thermometers, given pages 172-308, are not corrected for the errors of the thermometers ; but the corrections have been applied to the abstracts of results, pages 404—412. 92. The maximum and minimum self-registering thermometers, on RUTHER- FORD’S construction, were made by ADIE and Son; they were attached to a frame fixed to the north side of the Observatory, about three feet from the ground, and near the dry and wet bulb thermometers. MET. AND MAG. OBS. 1844. A self-registering mercurial thermome- P lvill INTRODUCTION TO MAKERSTOUN OBSERVATIONS, 1844. ter, with a black bulb, by R. AprE, of Liverpool, was placed, in the end of May 1844, within the enclosed space occupied by the Observatory rain-gauge, exposed to the sun, for the purpose of obtaining the maximum amount of solar radiation ; another self-registering alcohol thermometer, with black bulb by the same maker, was placed near the other in September 1844, with its bulb in the focus of a para- bolic metallic reflector, for the purpose of obtaining the minimum of terrestrial radiation. The observations of the self-registering thermometers are given pages 310-312; they have all been corrected for the scale errors of the thermometers. 93. Another thermometer was employed for the determination of the tempera- ture of the water in two pump-wells, which are within about 200 yards of each other ; the pumps are nearly on the same surface-level, the depth of the cottage- well being 10 feet,—that of the garden-well 21 feet. On one occasion, it was found that there was one foot of water in the cottage-well, and two feet of water in the garden-well. In obtaining the temperature, the water was pumped till the reading of the thermometer remained constant. All the observations have been corrected for the scale error of the thermometer used. ACTINOMETER. 94, The actinometer was made by STEVENSON of Edinburgh; it consists of a hollow cylinder of glass filled with ammonio-sulphate of copper. One extremity of the cylinder is joined to a thermometer tube, terminating in a hollow bulb; the other extremity is cemented to a metallic cap, through which a screw, working in a collar of leather, passes into the cylinder; a scale of 100 divisions is attached to the thermometer tube; the whole is inclosed in a larger glass cylinder of two inches diameter. A portion of this cylinder, opposite the liquid, is inclosed by a segment of a metallic cylinder, blackened within. In making an observation, the inner cylinder was exposed to the sun’s rays at a perpendicular incidence for 60 seconds, the scale readings of the fluid in the tube being observed at the beginning and end of the minute. A screen was then interposed for one minute, or for one minute and a half; if for one minute only, the last observation in the sun was also noted as the first in the shade ; if for one minute and a half, the first reading in the shade was not made till the instrument was shaded half a minute. At the end of 60 seconds the scale reading was again observed, and the screen was removed, that reading being also noted as the first in the sun. When the liquid mounted near the top of the thermometer tube, the screw was withdrawn nearly half a revo- lution, when the liquid fell to near the bottom of the tube. The times were noted from a box-chronometer by Dent, No. 1665. In February 1844, the liquid in the cylinder was frozen while the instrument was in the Observatory, and the cylinder was broken, The following were the dimensions of this actinometer :—liquid cylin- der, 54 inches long; mean external diameter, 1013 inch ; mean internal diameter, ACTINOMETER. lix (0-924 inch; thermometer tube, 64 inches long; the mercury, filling 2:9 inches of the tube, weighed 11°5 grains, and 100 divisions of the scale are equal to 5:51 inches. The screw, which is of silver, is 24 inches long, and has 25 threads to an inch, the diameter at the outer edge of the screw is 0°57 inch, and at the bottom of the screw is 0°53 inch in diameter; it was not possible to determine the amount of heat stopped by the outer cylinder, as both cylinders were screwed to the same end-piece. 95. In the summer of 1844, a new actinometer (with the old screw) was ob- tained from the same maker. The cylinder and thermometer tube were inclosed in a mahogany box, open at one side ; the compartment containing the cylinder filled with the blue liquid is lined with black velvet, and is covered by a slip of plate- glass. The dimensions were as follow:—Glass cylinder, 54 inches long; mean external diameter, about 1:05 inch; the mercury, filling four inches of the thermo- meter tube, weighed 16°7 grains; the length of 100 divisions of the scale are equal to 5°5linches. The cylinder of this instrument was again destroyed in the winter of 1846-7, by the freezing of the liquid. The previous dimensions of the cylinder belonging to the actinometer, from June 1844 till February 1847, are considered to be very near the truth; they are, however, only given from the dimensions of the cylinder in the actinometer at present, which is of the same size. The ac- tinometer was placed in a small revolving frame during observations after June 1844, by means of which the face of the actinometer was always presented to the perpendicular incidence of the sun’s rays; at the end of the same table upon which the revolving frame was placed, a double wooden screen was hung by cords passing over pulleys; the instrument could be shaded or exposed to the sun by the observer instantaneously. The following are the results of series of observations for the amount of heat stopped by the plate-glass used in the instrument after June 1844, and marked A :— Se. Div. 1846.

Besides the breaking of the cylinders by the freezing of the liquid, the instrument has been rendered useless for good experiments several times by the deposition of a brownish oily sediment, which finds its way into the thermometer tube, and this though the liquid had been long prepared by the maker. When this deposition of sediment occurred, the instrument was sent to the maker to be cleaned ; the observations, therefore, in this volume, are nearly unaffected by it. RAIN-GAUGES. 97. The Observatory rain-guage is placed in a space, enclosed by a paling on the top of the Observatory hill, with a good exposure on all sides. The funnel-mouth is 6:1 inches in diameter, 8 inches above the soil, and 218 feet above the level of the sea. The quantity of rain is measured at noon by pouring it into a glass tube, graduated with reference to the aperture of the funnel. 98. The monthly results of two other gauges are given in the abstracts. One is placed on the top of the greenhouse roof, 680 feet NNE. of the Observatory gauge ; the funnel-mouth is 6°7 inches in diameter, it is connected with a graduated tube within the greenhouse, it is 18 feet from the ground, and 192 feet above the level of the sea. This gauge is sheltered to the E. and NE. by trees, and its indica- tions are therefore less trustworthy, especially during easterly winds ; the amount of rain received in the funnel is also affected by the gusts of wind deflected from the sloping roof. 99. The other gauge is in the middle of the Makerstoun garden, with a good exposure; the funnel-mouth is 6:7 inches in diameter, is 61 feet above the soil, 171 feet above the level of the sea, and about 620 feet N. by E. of the Obser- vatory gauge. The funnel is connected with a graduated tube. The greenhouse and garden gauges were observed by Mr MaccGatt, the head gardener, the former daily, the latter monthly. VANES AND ANEMOMETER. 100. The vane is placed on the north wall of the Observatory, and by means of a rod and geering-wheels it indicates the direction of the wind on a dial-plate within the building ; this vane (occupying the position W’ in the plan, Plate I.) was found too heavy for light winds, and the directions of these were estimated for some time from a ribbon-vane. On July 6, 1844, a small vane formed of two crow feathers (one from each wing) placed back to back, was erected above the door of the Observatory. This vane was not connected with any dial-plate, and the direc- VANES AND ANEMOMETER. xi tion of the wind could be estimated from it during the day only. On November 13, 1844, a larger vane was formed of four large feathers from a turkey’s tail, this vane was mounted on a long and light fir-rod, which passed through the roof of the Obser- vatory, and had an index attached to its lower extremity, which indicated the direc- tion of the wind on a compass fixed to the ceiling of the Observatory. This vane indicated the direction of the lightest winds, and the direction of the wind was gene- rally taken from it after November 13, 1844. The direction of the wind is indi- cated in this volume by the number of the point of the compass, reckoning N = 0, E =8, S=16, W = 24. 101. The anemometer, the invention of Mr R. ADIE, of Liverpool, was made by Messrs ADIE and Son, of Edinburgh; it occupies the north-east corner of the Obser- vatory. This instrument will be best under- stood by a reference to the annexed figure : @ is a cistern containing water to the level b, c being a turn-cock for letting the water off to the exact level, and da glass-gauge to shew when the water becomes too low, from eva- poration or otherwise ; an inverted vessel e is suspended in the water by a cord passing over the wheel 7, whose axle rests on friction- rollers at g and A; 71s a spiral, which has a cord wrapped onit carrying a weight k, which balances the vessel ¢; / 1s a dial, graduated on the face near the circumference ; m an in- | dex, attached to the common axle of the wheel and spiral ; n a loose index under the index m, which the latter carries forward by j means of a projecting pin near the extre- mity; 0 a tube passing under the cistern a, which, entering the bottom, proceeds upwards within the vessel ¢ till its open extremity is above the level of the water in a neck of the vessel e; the other end of the tube o is six feet above the outer wall of the Observatory, where it is capped by a vane p; at the top of the tube o three brass rods are joined, which carry a small tube in which a pin within the top piece g rests or turns ; the tube o is double at the top, containing between the tubes a quantity of mercury to the level r, the continuation of the cylindrical body of MAG. AND MET. OBS., 1844. q Ixii INTRODUCTION TO THE MAKERSTOUN OBSERVATIONS, 1844. the vane enters the mercury, and a double portion s acts as an outer cover to the mer- cury cistern ; ¢is an aperture, 2 inches square. When the wind blows, this aperture is presented to it, the wind then presses on the column of air within the tube o (being prevented from escaping under the vane by the mercury), and ultimately on the top surtace of the vessel e, forcing the latter up, turning the axle carrying the index m, which carries before it the index n, leaving it at its farthest excursion. The dial is graduated as follows :—The surface of the top of the vessel ¢ on which the wind presses is 78 square inches, therefore a pressure of 1 lb. on this surface is equivalent to 144 lb. on a square foot. Different weights are suspended on the wheel /, acting oppositely to the vessel e, and the position of the index for each weight shews the pressure on a square foot of surface equal to the weight suspended multiplied by the above ratio. ‘The spiral, on which the weight & acts, is the involute of a circle whose : R ; : : y radius 7 = = where R is the radius of the wheel 7, and 2 7 is the circumference to radius of one, if the vessel e were homogeneous throughout its depth, the equal in- crements of motion in the index would correspond to equal increments of pressure.* 102. The instrument is observed in the following manner :—About 2™ before the observation hour the pressure shewn by the index v is registered as the maxi- mum pressure ; this index is then put back to zero, and from 7™ to 10™ afterwards, the position to which it has again been carried by the index m is noted as the pre- sent pressure ; the index n is then set to zero, and a similar double observation made at the next observation hour. It is conceived that this instrument can be de- pended on for the purpose of determining the laws of variation of the pressure of wind ; for absolute results, an integrating instrument is essential. STATE OF THE Sky. 103. The extent of sky clouded is estimated ; the whole sky covered with clouds being noted as 10, and the complete absence of clouds as zero. The motions of the clouds are determined as follows :—A well-marked portion of cloud which passes, or has passed, through the zenith, 1s watched till the direction is found in which it seems to run down, or parallel to, one corner of the Observatory ; the walls of the * The application of the involute of the circle as the spiral is due, I believe, to Professor Forzzs.

Lxut Observatory are in the meridian and prime vertical, and the points of the compass, reckoning from each corner as a centre, are marked upon the paling surrounding the Observatory ; the observer, therefore, sees at once the direction of motion of the cloud on the paling ; when a portion of cloud cannot be seen which has passed, or is about to pass, through the zenith, it is generally easy to determine very nearly the vanishing point of the motion of any portion of cloud, by watching its progress for a short period ; there can be no hesitation in saying, that the motions of the upper currents of air thus observed, are better determined than the motion of the lower or surface current observed from the vane. The directions of motion of the clouds in three strata (scud, including cumuli; cirro-stratus, including cirro-cumuli; and cirri), are given in numbers of points of the compass, reckoning N = 0, E = 8, S= 16, W=24. The nomenclature adopted is that of Mr Howarp, with certain combinations, which are, in general, sufficiently descriptive. 104. After June 30, 1844, full sunshine is indicated in the column of meteoro- logical remarks by the symbol © ; when the sun shone through a cloud so as to pro- ject a distinct shadow, it is indicated by the symbol © ; when the cloud was very thin, this was indicated occasionally by the symbol © ; and when the sun’s disc only was visible, the symbol @ is used; similar symbols are used for the moon. 105. The heaviness of the rain falling at the time of observation has been esti- mated after May 10°, and is noted in the column of meteorological remarks, upon the supposition that the heaviest fall is 10: thus, rain®, is rather heavy rain ; rain’, is the heaviest observed in 1844; rain®’, is just perceptible ; and rain®’, is a light, spitting, Scotch mist. CLOCK. 106. The mean time clock is by Dent of London ; itis kept at Gottingen mean time by comparisons with the transit clocks in the Astronomical Observatory, the errors of which are determined by Sir THomas BrisBANE, by myself, or by Mr WetsH. The rate of the clock is kept small. DESCRIPTION OF THE TABLES OF OBSERVATIONS. 107. Hourly Observations of Magnetometers, pages 1-69. The first column contains the Gottingen mean solar time, astronomical reckon- ing, of the observations of the declination magnetometer. Gottengen time is 49™ 50° in advance of Makerstoun time. The second column gives the absolute westerly declination in degrees, minutes, and decimals of a minute, deduced as described, No. 17. The third column contains the observations of the bifilar magnetometer in scale divisions, corrected for temperature to 26° Fahr., see Nos. 69 and 73; increasing numbers indicate increasing force. The bifilar is observed 2™ after the declination. lxiv INTRODUCTION TO THE MAKERSTOUN OBSERVATIONS, 1844. The fourth column contains the temperature of the bifilar magnet in degrees of Fahrenheit. The fifth column gives the readings of the balance magnetometer in micrometer divisions, corrected for temperature to 26° Fahr., see No. 79; increasing numbers indicate increasing force. The balance is observed 3™ after the declination. The sixth column contains the temperature of the balance magnet in degrees of Fahrenheit. The seventh column contains the observer’s initial, see No. 5. At the foot of each page the time is given during which the declination mag- net has remained untouched, or the amount of torsion found in the suspension thread when that has been determined, see No. 12. The value & of one scale division of the bifilar magnetometer, the whole horizontal component being unity (see No. 38), and the value of k of one micrometer division of the balance magnetometer, the whole vertical component being unity, are also given; the value of the latter given here, 00000085, was deduced from observations made in 1846 (see No. 59), and is erroneous, the true value is k=0-000010 (see Nos. 58 and 59); this value has been used in the abstracts of results. 108. Term-Day Observations of Magnetometers, pages 72-89. The first column contains the minute of Gottingen mean time of the declina- tion observations, the hour being given in the middle of each triplet of columns. The second and third columns contain the bifilar and balance magnetometer readings, reduced to the temperature of 26° Fahr., as in the hourly observations. The temperatures of the magnets at the commencement of each hour will be found with the hourly observations, and the observer’s initial for each hour are in the same place. The corrections for temperature are applied to the observations in the fol- lowing manner :—The correction to the first observation of each hour being applied for the known temperature of each magnet, the temperature is supposed to change uniformly throughout the hour, and the corrections for the intermediate observations are interpolated between the initial corrections. 109. Hatra Observations of Magnetometers, pages 92-157. These observations are made generally during magnetic disturbances. The same remarks apply with reference to temperature corrections, &c., as for the term- day observations, excepting that the Gottingen day and hour are given in the first column, and the minute is given for the observations of each instrument. Notes upon the Aurore boreales observed are given, with the times of the phenomena in Gottingen mean time. 110. Observations of Magnetic Dip, and for the Absolute Horizontal Intensity. See Nos. 19, &c., and 84. 111. Hourly Meteorological Observations, pages 172-308. The first column contains the day and hour, Gottingen mean time, of the obser- vations, all of which are made within a few minutes of the hour, and generally in DESCRIPTION OF THE TABLES. Ixv the order noted below. The Gottingen mean time is 49" 50° in advance of the Makerstoun time. The second column gives the height of the barometer, corrected to 32° Fahr., see No. 88. The barometer is generally observed between the ob- servations of the declination and bifilar magnetometers, that is, about 70° after the hour. The third and fourth columns give the observed readings of the dry and wet bulb thermometers in degrees of Fahrenheit, wncorrected for scale errors, see No. 91, and the fifth column gives the difference of the observed readings of the two thermo- meters. The dry and wet bulb thermometers are generally read about 14™ before the hour. The sixth column contains the maximum pressure of wind on a square foot of surface which has occurred since the previous observation, see No. 102; this maximum is generally noted, and the index set back 2™ or 1™ before the hour. The seventh column contains the maximum pressure of wind on a square foot of surface within from 8™ to 10™ at the time of observation, namely, from 2™ or 1™ before the hour till 6™ or 9™ after the hour. The eighth column contains the direction of the wind read from the dial-plate of the vane, and given in numbers of points of the compass, reckoning N =0, E = 8, S = 16, W = 24. The ninth column gives the directions of motion of three strata of clouds in numbers of points of the compass, namely, of scud, cirro-stratus, and cirrus ; thus, September 254 2", the surface wind, by the vane, blowing from 22 (WSW.), the scud was moving from 24 (W.), the cirro-cumulo-stratus was moving from 27 (NW. by W.), and the cirri were moving from 30 (NNW), see No. 103. The tenth column contains the estimated extent of sky clouded, the whole hemi- sphere covered being 10. The eleventh column contains the species of clouds observed, with other meteor- ological notes, see Nos. 103, 104, and 105. The observer’s initial will be found at the corresponding hour of hourly mag- netical observations. 112. Daily Meteorological Observations, pages 310-312. The first column contains the civil day of observation, and the first column of each triplet of columns thereafter contains the minimum temperature noted from the self-registering thermometer about 10 a.m.; the second column contains the maxi- mum temperature noted from the self-registering thermometer at 5" p.M., see No. 92; and the third column contains the amount of rain found at noon in the Observatory rain-gauge. In page 311, the temperature of water in two pump-wells is given, see No. 93. In page 312 are given the maximum temperature of solar radiation, and the minimum temperature of terrestrial radiation for portion of the year, see No. 92. 113.

Curves of Term-Day Observations, Sc. The term-day observations, as corrected, pages 72-89, having been projected and drawn with the greatest accuracy by Mr WELsH on lithographed curve paper, they have been transferred by the anastatic process, in 12 Plates, given at the end of the volume ; the remaining plates similarly drawn and transferred are Plate XIV., containing the projections of the daily means of the observations of the three mag- netometers as given Table I., page 330, Table X XII. (in scale divisions), page 355, and Table XX XVIII. (in micrometer divisions), page 373. The projected means for the horizontal component exhibit the law of variation for the relative positions of the sun, moon, and earth (the moon’s age being the argument), in several lunations, see page 358. Full moon is indicated at the head of the Plate by the symbol o, new moon by @. Plate XV. contains the projections of the diurnal ranges of the three magneto- meters, from Table IIT., p. 335, Table XXIV. (in scale divisions), page 359, and Table XL. (in micrometer divisions), page 376: it also contains the projections of the approximate daily mean disturbances for each instrument, that is, the mean differences of a single observation in each day from the monthly mean for the corre- sponding hour, as obtained from Table XIV., page 346, Table XX XIV., page 368, and Table L., page 385. The projections on this Plate also exhibit the laws of varia- tion with reference to the moon’s age. Plate XVI. contains the projections of the hourly means for magnetical and meteorological observations. The hourly means obtained from all the magnetical observations are projected in continuous lines; those obtained from the 60 days in the year most free from intermittent disturbances (see page 338) are projected in . DESCRIPTION OF THE PLATES. Ixvil dotted lines. The declination, from the last column of Table V., page 337, and of Table IX., page 340. The horizontal component, from the last column of Table XXVIL., page 360, and of Table XXIX., page 362. The vertical component, from the last column of Table XLII., page 378, and of Table XLV., page 380. The inclination, from the last column of Table LV., page 391, and from line 19, page 392. The total force, from the last column of Table LVIII., page 396, and from line 19, page 397. The meteorological curves are projected from the following Tables :— The barometer, from the last column of Table X XII., page 423. The temperature of the air, from the last column of Table III., page 407. The pressure of aqueous vapour, from the last column of Table XIII., page 415. The relative humidity, from the last column of Table XVII, page 418. The pressure of wind, from the last column of Table XX XII., page 430. The direction of the resultant pressure of wind, from the last column of Table XXXVI., page 439. The extent of clouded sky, from the last column of Table XLI., page 444. All the reductions connected with the quantities given in this volume have been made by my assistants, Messrs WELSH and Hoee, and by myself: each computation has been performed twice at least, and that generally by different individuals.

Auroral light very faint. (Sunday evening.) Brilliant aurora seen by me first at this time, it had been seen sometime before by Mr Hogg, and shortly before by Mr Welsh. At 10" Mr W. conceived the centre of the auroral arch’ to be nearly north. The only clouds were to north, almost covering the aurora; they stretched in a series of belts or arches from about WNW. to E. The extremity to east had a sort of cycloidal rise, similar to what I have before observed in auroral arches. 25. The moon apparently rising due east; at an altitude of about 15° above it, and at the edge of the cir- rous clouds, spring a series of streamers lying en echelon, they reach about as far as 45° above the SE. At some times it was imagined that the streamers were seen below the cirrous cloud, but as the cloud was thin the streamers were probably only seen through it. 30. The streamers rising from the east, where the moon has now risen, are inclined at an angle of about 30° to the south of the prime vertical ; they are seen as far as the meridian, where the streamer is joined by another rising from the SW. ‘These streamers are at times in patches, pulsating and variable ; those rising from east have now a more compact form. 35. Faint auroral patches to SW. variable. 40-45. The patches to SW., nearly radiate from that point, are varying in size and brightness, with occa- sional rapid pulsations ; ultimately they took positions nearly horizontal, slightly (10°—20°) above the south point of horizon, but still pointing to about SW. In this position they were observed till after 11", and were nearly stationary ; indeed, had they not been closely watched during the whole period they would undoubtedly now have been taken for nebulous patches of cirri lighted by the moon. It is necessary to be particular on this point, as I have frequently seen similar appearances in which I could have no confidence as to whether they were auroral or not. In this case, however, they were seen from their formation varying in brightness and form with, rarely, rapid pulsations, until they were nearly stationary to south, without any auroral changes, although slight changes in J position were observed after a considerable watching. About 40™ the streamers to east became one bright pencil, moving slightly to south, its origin now pointing E3S., and the highest point bent like a hook to south. 40-45. Two very bright falling stars seen to west, one moving from about 40° altitude west to about 20° altitude W by N., direction nearly to WNW ; the other moving from about 70° altitude W by N. to 50°? altitude WSW., motion about SW. _ 50. Falling star to south, 45° altitude, moving S. by E. among the streaks of aurora. About 45™ pencils were seen rising from WNW. portion of the north arch, which was nearly all covered by cloud as before mentioned; bright specks could, however, be seen occasionally to NNE., and the extremity of the arch at WNW. was always seen. It should be mentioned, that it was conceived that the aurora was always brighter to SW. than to the 8. or WSW. 10. Patches of thin cirro-stratus, chiefly to east. Thin haze or cirri above, causing a small lunar corona. Aurora faint, probably from the moonlight. Bright patches near north horizon. Nebulous streaks — and patches over the sky, which may be auroral, but the moonlight renders it doubtful ; about 12® patches or streaks were seen, having a strong resemblance to those seen previously to south. 35. Auroral light very faint to north. The aurora was observed by several persons before 8" Gottingen, and was, according to them, very | brilliant. Mr Welsh thought at 6" Gottingen that there was an appearance of aurora to north, but | conceived it might be a twilight-effect. OBSERVATIONS OF MAGNETIC DIP. ¥ \ MAKERSTOUN OBSERVATORY, 1844. «MAG.

The clouds have broken up about the zenith into watery-looking woolly cirro-stratus and thin milky haze, the horizon being still covered with dense clouds, and the sun quite obscured. About 60° of a remarkable halo (or iris) is visible; its appearance is between that of a rainbow and a coloured solar halo; its centre at or very near the zenith, and the radius somewhat greater than that of an ordinary halo, perhaps 25°; the brightest portion being between the zenith and the sun’s place. This was seen for about 2™ or 3™, when it disappeared, the clouds having become thicker in that part of the sky. Just as it disappeared, another became visible to the South at an altitude of about 35°, its convexity being turned in the same direction as that of the other; as only a small portion of it was visible, no estimation could be made of its radius; it was seen in an opening in the clouds similar to the first, and lasted about 1™. During the whole time a bright elongated spot was in the NNE, at an altitude of 7° or 8°, like the sun’s light struggling through a cloud; it disappeared about the same time as the second halo. Feb. 20 21 . A flock of wild geese seen flying towards SW. 23 1 . Sea-gulls seen flying towards the East. Mar. 4 18 6. A meteor, somewhat brighter than Venus, burst near the star ¢ Leonis; its course was in a line with Spica and % Leonis; only a few degrees of it were seen. 13 6 . Flocks of wild geese and gulls flying towards the East, 16-19 . Several gulls seen about this time. 22 7 ~~. A bat seen this evening. Apr. 6 . Large flocks of sea-gulls seen near the Observatory. 11 14 6—10. Several shooting-stars seen; one moved from Benetnasch past Mizar; another from near the zenith towards the South; another from near Altair towards the South; another moved westward between € Bootis, Mirach, and Alphecca; faint flashes of lightning, supposed to have been seen to SE. The sky was watched till 15"; no more shooting- stars or lightning were seen. The latter is doubtful, as the stars twinkle much. 165. A shooting-star moved from near Cassiopeia towards the East. 17 7 ~~. Woolly, mottled, and cirro-cumulous cirri; mottled-edged and clearly-defined cirro-strati detached from each other; the woolly cirri, in large masses, radiating and moving from about S. by W., the cirrous edges being turned upwards; some very small patches of loose seud rising on SE. horizon, and moving from SW. (?); hazy to E.; cirro-strati considerably lower than the cirri. 8". Nearly as before; sheets of cirro-strati nearly cover the sky; long strings of cirri; a few patches of scud moving from about SW. May 21 6 . Fine cirri; cirro-cumulous cirro-strati dropping in ragged fragments to SE.; cumuli and cumulo-strati; scud on SE. horizon; the ragged patches of cirro-cumuli are finely-rounded cumuli on the tops, and only ragged below; solar halo. July 18 4—7. 4" 0™, Huge piles of cumuli and cumulo-strati reaching almost round the horizon, and rising to 30° altitude; some of them with cirrous tops; sky milky. Thunder first heard at 4h 49™ to NNW.; two other peals in about 2™ after, rather faint. 55™.

The storm was watched throughout by two observers, B and W. Note.—The thunder commenced to SSW., passed by the W. of the zenith to NE., and went off finally to bh. . This storm differs considerably from any observed here previously; although there were large piles of cauliflower cumuli and cumulo-strati with scud throughout the day, yet there was none of that tormented appearance which the clouds generally assume previously to and during a thunder- storm. The scud seemed, as long as it could be observed, to move nearly from the same quarter, S., or 8. by W. The bolts of lightning seemed on every occasion to move nearly vertically and from ; below, upwards; in one instance, the bolt took the form of the cima reversa, and, like many of the others, seemed formed of a series of beads; some terminated in large balls enveloped in sheet lightning. Many of the flashes were so vivid, as to render sight difficult for some seconds. The rumbling of the thunder was often very irregular, having several breaks and starts, the sound being very various, from that of a distant waterfall to the sharp brattle of a railway-carriage starting. : | pt. 26 13.

The bands to E, and W. more broken than before, the central one, now completely on the meridian, seeming to form about 10° to the W. of it, and to dissolve about 10° to the E. of it. The central band has now disappeared, those to the E. and W. still remain. When first observed, the moon was to the E. of the meridian, and the central band, which lay in a southerly and northerly direction, seemed moving with considerable rapidity from W. to E., but never progressed, retaining almost exactly the same form and position; at last the moon attained the band, and passed behind it, a fine lunar corona being produced by the cloud. Ultimately the moon passed to the W. of the cloud, the band having moved perhaps 15° more easterly in the course of three hours, and seeming during the whole period to flow from W. to E. S. 4 W.

Thin cirrous clouds over the Moon, forming a whitish corona of two or three rings, the diameter of the greatest being about 1°; below this a thicker watery-like cirrous cloud at a short distance from, and on one side of, the Moon; this cloud seems to move, but still keeps at about the same distance from the Moon ; it forms a portion of a double corona, which assumes various forms, being at different times elliptical, boomarang-shaped, cir- cular, and square; the order of the colours, reckoning from the Moon outwards, is—yel- lowish, passing into orange, next a dark space, then blue and orange again ; the outer side of the inner orange may be 3° to 5° radius, and of the outer orange 43° to 64° radius.

A band still continues in nearly the same position, esti- mated to be 6° broad, and consisting of six or eight separate streaks lying in juxtaposition ; separately having a considerable resemblance to the cometary beam of aurora seen on March 29, 1843. (See Volume of Observations for 1843, page 61.) The band can be traced from the horizon at N. 131° E. to 8. 44° W., ernie 28°; at the centre of the arch, azimuth W. 10° N., the altitude is 69°. 36™, The clouds clearing off a little to S. ; | the band is observed to stretch to within 5° of the horizon, being there cut off from view by a band of cirro-stratus; the azimuths of the extremities are N. 8° H. and 8, 13° W.; | altitude of summit, upper edge 80°, lower edge 48°, the measurements rough. 40™, A meteor shot from B Cygni, at the summit of the arch, towards the 8. in the direction of | the band; N. extremity obscured by clouds; 8. extremity increased in intensity and breadth ; the light dullish white ; a very bright ‘portion to S., altitude 24°. 45m, A streak to the E. of the arch, springing from the S. extremity, has newly appeared, and ultimately extends across the zenith. 50™, The breadth of the band at the summit is 40°, extend- ing from altitude 50° to zenith ; the structure as of a series of fibres more or less dense, 8° or 10° of it being nearly uniform. 55™. Another measurement of the breadth of the arch at the summit gives the breadth 51°, the lower altitude being 39° and the upper 90°; no error in the previous measurement, the arch having extended farther W. 9 0™. Sky obscured by clouds. 9 30™. Sky clear; the streaks at first scarcely visible, afterwards observed faint in the zenith. A streak observed, very fine and faint, in the same direction as before described, its length about 10°; gradually creeping up, increasing in breadth and intensity, and afterwards extending over the zenith; three or four afterwards forming as before. It may be remarked, that the atmosphere seems very humid, a dull milky light being around the Moon, while patches of scud are continually forming ; at one time lunar beams observed, caused by the rays shining through holes in the clouds ; but the Moon is completely to the E. of the bands observed and can have no connection with them. It is very difficult to determine whether these bands are cirrous streaks or not; but their well defined edges, varying breadth and brightness, and great extent of space, leave upon the observers the impression that this is a phenomenon of a very different kind. It is cer- tainly very strange that the streaks should re-form in exactly the same position. The Moon being nearly full (and at about 8" 50™ having an altitude of about 35°, and being 50° to E. of meridian), rendered it more difficult to watch the varying phases of this phenomenon. No upper range of cirrous clouds was observed either to E. or W. of this band, which was evidently above the cirro-cumuli and scud. Observers, B. W. and H. There was a magnetic disturbance which finished immediately before this phenomenon was noticed. ov. 24 8.

MEAN DECLINATION AND THE SECULAR CHANGE. The mean westerly declination for the year 1844, The mean westerly declination for the year 1843 (1843, p Hence, the value of the secular change for the year 18434 The secular change for the year 1842-8 (18438, p. 224), 221), Holl fl dl 25° 17°06 25 22°85 — 5-79 — 5°62 We may therefore conclude that the yearly diminution of westerly declination was nearly constant from 1842 to 1844, or that the north extremity of the declination needle approached the true north at the average rate of 570 a-year. MAGNETIC DECLINATION. 331 ANNUAL PERIOD. An examination of the monthly means at the foot of Table I. will shew that though the amount of change from year to year be nearly constant, this is not the case from month to month; on the contrary, the north extremity of the needle at times moves towards the west. It is not very evident, however, from these means, whether the rate or sign of motion has any well-marked relation to the season of the year. In order to render this more apparent, we may separate the variations into two parts; one, consisting of an easterly motion (the north end of the needle being always considered), at the constant rate of 048 a-month, or 570 a-year ; the second, of motions which are alternately to the east and to the west of the same mean position,—the latter being evidently the only portion which can have any relation to season. If, then, n be the number of the month from January, and we add the quantity 0°48 n to each monthly mean, we shall obtain the following quantities : Jan. Feb. March. April. — May. June. July. Aug. Sept. Oct. Nov. Dec.

The whole range of these means, however, is only 212, and as the effect of 10° of torsion in the suspension thread is 0’-84, it is quite possible that some of these variations may be due to this source of error. Though an examination of the amount of torsion, found at different times in the suspension thread, will shew that the error due to torsion is, in general, small,* yet it will be desirable to destroy accidental errors as much as pos- sible by taking the means of groups; making use, for this purpose, of the mean for December 1843 = 18/-72, and for January 1845 = 19'85 (both reduced for secular change to January 1844), and noting the mean for each three months as the mean for the middle month, we obtain the following quantities for 1844 :— Jan.

The variations upon which the latter portion of this result depends are too smal] to be entitled to much confidence alone; the Observations for 1843 have, accord- ingly, been discussed anew for the purpose of comparison with this result. In the volume for 1843, the monthly means from 9 daily observations were corrected by quantities obtained from the 24 hourly observa- tions of 1844 (1843, p. 221). Correcting the means for 18438, and for December 1842, by the complete series in 1844 and 1845, we have the following quantities :— Dec. Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Nov.

Very nearly the same result as may be deduced from these quantities is exhibited by the simple means for each of the succeeding years, 1845 and 1846; it is therefore stated with considerable confidence, that the mag- netic declination at Makerstoun has an annual period, consisting of a motion of the north end of the needle towards the west from April till August or September, of an easterly motion from September till the end of November, of a secondary westerly motion from thence till February, and of an easterly motion from thence again till April. It should be remarked that this result differs little from what might be at once concluded from the simple monthly means for 1844, and (with the exception of the principal westerly deviation) from the simple monthly means for 1843; in the consideration of the annual period from the means for 1843 (1848, p. 221), the secondary maximum and minimum were overlooked as possibly accidental, which might have been done still” but for the strong confirmation of each successive year’s observations. Differences of the Daily Means from the Monthly Means.—The following are the means of these differences for each month in 1844 :— Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Nov.

Feb. March. April. May. June. July. Aug. Sept. Oct. Nov. Dec. 0°59. 0-55, 0°54... .0°48 0°48. 10°48 0-48 = 0°59) 070) 08691 Ob wae The average differences are therefore a minimum about May, and a maximum about September, a secondary minimum occurring about December, and a secondary maximum about January ; the latter are more distinct in the simple means. It is impossible not to remark the coincidence of these epochs with those stated already for the mean westerly declination. The result may be thus generalized :—The average difference of the daily means from the monthly means in 1844 was a minimum when the mean westerly declination was least, and a maximum when it was greatest. The previous quantities may perhaps be considered as some measure of the amount of disturbances of the daily mean positions in each month of the year, without distinguishing, however, between what we may term consecutive disturbances, or those which are due to a regularly varying cause (as the lunar phase or declination) and intermit- tent disturbances, or those which are irregular in amount, and occur at intervals. Since the sum of the posi- tive differences is necessarily equal to the sum of the negative differences, if we divide half the sum in each month by the number of days for which the mean westerly declination was greater than the monthly mean, and also by the number of days for which it was less, we shall have the average of the positive and of the negative differences in each month. These, with their differences, are as follow :— Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Noy.

As in some lunations the 29th day was want- ing, the mean westerly declination for the 28th and Oth day was used instead. For the variations with reference to the moon’s declination, the 13 days on which the moon was farthes north between January 3 and December 23, 1844, were numbered 0, the days after these were numbered 1, 3,. . . 26 or 27; in cases in which the moon was again farthest north at the 27th day, the mean westerly de- — chination for the 26th and Oth day was used for the 27th, the mean westerly declination for each day was then obtained, and after correction for secular change as before, the differences from the lowest mean were entered in — the following table. “a For the variations with respect to the moon’s distance from the earth, the days between January 7 4 December 30, 1844, before and after apogee and perigee, were numbered from 1 to 7, in some instances the: MAGNETIC DECLINATION. 333 were only 11 days between apogee and perigee, or between perigee and apogee ; in these cases, the 6th day was counted as the 6th and 7th before and after the two epochs ; where there were 12 days of interval, the 6th before apogee was counted as the 7th after perigee, and vice versa ; when there were 13 days of interval, the 7th was counted as the 7th before the one epoch and after the other; and when there were 15 or 16 days, the mean westerly declination for the 7th and 8th day was used as a mean for the 7th day. The mean westerly declina- tion for each of the 13 days so numbered was then obtained and corrected for secular change, as in the first case ; the differences from the lowest mean are given below. ; TABLE II.—Mean Variations of Westerly Declination after Eliminating the Secular Change, with reference to the Moon’s Age, Declination, and Distance from the Earth, for 1844.

Note.—In the discussions with reference to the moon’s age, declination, and distance from the earth, it should be remarked, that since 12 lunations occur in nearly the same time as 13 revolutions with respect to node or with respect to apogee, any variations in the element discussed, due to changes in the moon’s declina- tion or distance, will be eliminated in the mean of 12 lunations; and similarly in the means of 13 revolutions with respect to declination or with respect to distance, variations related to changes of phase alone will be elimi- nated ; but this is not the case in the combinations for declination and distance, with respect to each other. Variations of Westerly Declination with reference to the Moon’s Age.—The general appearance of these variations, is that of a principal maximum about 3 days after the full moon, and a principal minimum between the 7th and 13th day; there are several secondary maxima and minima, as might be expected where the varia- tions are so small, and the uneliminated sources of error so considerable. It is only from a mean of several years that a satisfactory result may be obtained.

Variations of Westerly Declination with reference to the Moon’s Declination.—The following are the means of groups for 1844 :— 27 days to 1 ie Moon farthest North, 0°50 13 days to 15 eh Moon farthest South, 033 Dylh.adae. 5 0-26 AG! eds 20™ after the superior transit, and the secondary minimum about 4 hours before the inferior transit. The range of the variations is about 1’-0. When we compare these results, with those already obtained for the sun’s hour-angle, we find, that whereas the diurnal variation due to the sun has its greatest range in the summer half-year, the reverse is the case for that due to the moon which is greatest in the winter. It should be remembered, however, that in several respects the winter is to us for the moon, what the summer is for the sun. In winter, we have the greatest amount of moonshine when the moon is north of the equator. In winter, the moon is in opposition to the sun, when the former is north, and the latter south, of the equator; whereas it is the sun which is north, and the moon south, of the equator, at opposition in summer. It does not seem improbable, then, that the diurnal variation due to the moon may have a variable character through each lunation, in a manner analogous to the change of the solar diurnal variation from summer to winter, from the greatest north to the greatest south declination, If this be the case, the lunar diurnal variation will not be eliminated in the usual summations for the solar diurnal variation, and, in such a fact, we might find some ex- planation of the secondary maximum which is exhibited most distinctly in the solar diurnal variation for winter. The minimum of westerly declination occurs when the sun and moon are on the same declination circle, —that is, about 5 or 6 hours before the superior transit; but the maximum occurs for the moon when near its inferior transit, and for the sun when past its superior transit. Several of the single lunations shew the results given above with considerable accuracy, and the verity of the results has been confirmed by the discussion of the observations for 1845, which will be found in its proper place. Intermittent Disturbances. Since in the process of selecting the series of 120 and 60 days, those days only were adopted which were free from all large disturbance, the 60-day series probably being nearly free from disturbance even of the smallest class, it is evident that the differences between the means for these series and the means for the whole series of observations should indicate the law, and approximately the amount, by which intermittent disturb- ances affect the continuous variations. The following are results of the comparisons of the undisturbed series with the complete series :— Effect of Intermittent Disturbances on the Yearly Mean Declination.

GO... a On | 0 Oa ee ee ee Se ee ee ee i i i ee i i rary Sno ee a ee ee ee en a rr a This remarkable result proves that intermittent disturbances have no effect on the mean position of the declination magnet for the year; and, therefore, that in the course of the year the integrals of the disturbing forces are equally positive and negative. Effect on the Monthly Mean of Declination—If the days selected had been regularly distributed over each month, this result might have been expected with some accuracy ; this regularity of distribution, however, could not be obtained in consistence with the other condition of freedom from irregularity; and the means for the selected days in each month may be expected to differ from the true mean, were it from the effect of secular change alone. The differences are small even with this drawback. The average difference (independent of sign) of the mean for the 10-day series from the true monthly means being only 0/71, the greatest difference being 0’-2 ; and for the 5-day series, the average difference is 0-2, and the greatest 0°46. It seems therefore very probable that the effect of intermittent disturbances upon the mean position of the magnetic needle for a month is also zero. A comparison of the daily means renders it extremely probable that were a sufficient number of observa- tions made use of to obtain the true mean on days of much disturbance, the results would not differ more from the means for undisturbed days at the same epoch than would be accounted for by the regular laws of variation. __ Effect of Intermittent Disturbances on the Hourly Means of Declination.—The following Tables contain the differences, for each month, of the hourly means obtained for the whole hourly observations, from those for the selected series of 10 days and 5 days. 344 RESULTS OF MAKERSTOUN OBSERVATIONS, 1844.

After this, the mean effect of disturbance again increases, but in the opposite direction, being wholly to the west ; it becomes a maximum when the sun transits the magnetic meridian, after which it diminishes to zero at the transit of the magnetic prime vertical. This law will be found to hold with more or less regularity, depending on the nature of the disturbance in each ‘month of the year.

As has been already stated, the 60-day series is nearly free from even the smallest irregularities; but this is not the case with the remaining 60 days which complete the 120-day series ; these are affected by some small disturbances. It is quite possible that the smaller irregularities may obey some other law than that of the larger ; if so, it should be exhibited by the differences of the means for the 120-day series (which is affected by the smaller irregularities), and for the 60-day series (which is nearly free of them), These differences are as follow :—Means for 120 days, minus means for 60 days. 12h 13% 14h 15h 16% 174 18 194 20h 21h 22h 23h —0"°25 —0'24 —0'21 +0°09 +0°02 +0°10 +0°-06 +0°01 +008 +0:20 +021 +4026 Oh qh Qh gh 4h 5h 6h 7h gh gh 10» Lh + 0°33 40°28 +0°27 +0°14 —0°01 —0'°04 —0°09 —0"12 —0°26 —0’26 —0°20 —0”29 The law, it will be observed, is still nearly the same, the difference in the epochs being altogether trifling, when the smallness of the quantities is considered. From this, then, it appears extremely probable that the sinallest irregularities obey the same diurnal law as the larger, if not the largest. Few, if any, of the largest disturb- ances occurred in 1844; it is probably on this account that the general laws of disturbances are shewn with so much regularity in that year; a regularity which one or two of the largest disturbances would have destroyed, and which could only be obtained again by grouping several years’ observation. It is extremely probable, how- ever, since the smallest and the larger disturbances obey the same law, that the largest will not be found an ex- ception when a sufficient number of them are included in the discussion. It is obvious, that by selecting the five days of next greatest regularity in each month and the next five, series of means would be obtained representing the diurnal variation, for all the days in each month, for 20, 15, 10, and 5 days, in each of which series the effect of disturbance would become less and less ; in this way, by a method of limits, we might approximate to the normal form of the diurnal variation. In the previous investigation, only the mean effect of disturbance on the normal position has been con- sidered, we are therefore still ignorant of the law of the mean disturbance, for it is evident that the effect of disturbance on the true position may be zero when the mean disturbance is a maximum, the value of the former depending principally on the positive and negative distribution of the individual disturbances with respect to the mean position. At first, in order to obtain the mean disturbances, the difference was taken of each observation from the monthly mean of all the observations at the corresponding hours : as it has been shewn that the arithmetical mean of all the observations is not the normal mean, or mean independent of disturbance, this process is somewhat in- accurate ; it has, however, been employed at first, as the investigation of the differences of the individual obser- vations from their arithmetical mean is important in other respects: when greater accuracy is possible, allow- ance should be made for the variation of the daily means due to regular and continuous laws, such as annual and secular variations.

The law of the variations may be stated — as follows :—The mean difference of hourly observations from their corresponding monthly means is a minimum _ near the solstices, and a maximum near the equinoxes. This result is in accordance with that already obtained _ in the discussion for the diurnal range.

The result in this case, also, is the same as that obtained in the discussion of the diurnal ranges, namely, a maximum about the opposition, and a minimum near the conjunction ; there is the appearance of a secondary maximum at the conjunction, a minimum occurring a few days before it and a few days after it. The following are means of groups :— 14 days to 16 days, Full Moon, 2”18 29 days to 1 day, New Moon, 1-47 eee. 20°... 2":04 ey oy ae 1°35 bee. 24 ... 1-45 Ge, es ONY. 1°82 aees.. 20... 1-22 HOR tee lie hee. 225 So that the average difference of an observation from the monthly mean for the corresponding hour is about twice as great at opposition as at conjunction. Variation of the Mean Differences with respect to the Moon’s Declination—From the two preceding results (for the annual variation and moon’s age) it follows that maxima of the differences should occur when the moon ‘is near the equator, and minima when it is farthest north and farthest south ; that this is the fact, may be seen | from the second portion of Table XV., and also from the following means of groups :— 27 days to 1 day, Moon farthest North, 1°46 13 days to 15 days, Moon farthest South, 1'°53 / a 5 dee 197 NG HOT. 1-58 es Canes 1°80 AIM hs tees Wee fa 1°69 ee.

Diurnal Variation of the Mean Differences.—Tables XVI. and XVII. contain the mean differences for each hour in each month, each quarter, and the year. From the means for each hour for the year, it appears _ that the average disturbance is a maximum about 83" p.m.; the minimum occurs perhaps about noon, but the value of the average disturbance oscillates within small limits between 3 a.m. and 5 p.m. The two consecutive hours that have the highest mean value are 8 p.m. and 9 p.m., and the two that have the lowest mean value are noon and 1pm. Had observations been made at the even Gottingen hours only, the maximum would have been ex- hibited at 11 p.m. Makerstoun mean time.

Annual Variation of the number of Positive Differences.—The following are the numbers of differences in 100 which are positive in each month of 1844 :— Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Nov. Dec. 52°7 ~—s«81°8 51:4 484 49-7 52'8 50°0 = 49-9 530 46:0 489 55-3 In order to obtain more certain mean values for each epoch, the mean for each three months is given below as the mean for the middle month :— Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Nov. Dec. 53°33 52:0 505 49:8 50:3 50°8 50°9 61:0 49°6 49°3 50:1 02°3 From which it appears, that the number of excursions of the north end of the declination magnet, to the west of the monthly mean position in 1844, was a maximum in January and about July, and a minimum in April and October; or a maximum after the solstices, and a minimum after the equinoxes. The reverse, of course, holds for the number of negative deviations. Diurnal Variation of the number of Positive Differences—The numbers of positive differences in 100 for each hour of Makerstoun mean time for 1844, are as follow :— fot 22 gh gh 5h 6b 7h gh gh OR qibh Jobabpm. 2h gh 4h 5h 6h . 7h gh gh ~yoh , 11, 58°6 583 55-7 53-2 50°0 44-0 36-0 39°2 41°3 38:9 37:9 41°7 37°6 42:7 43:0 46:2 47°8 48:7 59:2 67:5 70:7 666 67°83 66-2 Whence the number of excursions to the west of the monthly mean position for each hour is a minimum about 9" or 10" a.m., and a maximum about 8 p.m. The reverse is the case for the number of excursions to the east of the mean position, and the numbers of positive and negative differences are equal about 4" a.m. and 5" p.m. This result is evidently related to that already obtained for the mean effect of disturbance. The previous conclusions have reference to the differences of the observations from their arithmetical ‘mean, which, it has been shewn, is in all probability not the normal mean; we are therefore still ignorant of | the actual sums of the positive and of the negative excursions at different epochs. These differences might | be determined approximately from the mean effects of disturbance, and the total sums of differences already | found; the error would be due solely to the observations occurring between the arithmetical mean and the | normal mean. The positive and negative sums of difference have, however, been determined, by employing the normal mean (as deduced from the five days of least disturbance in each month) instead of the arithmetical mean; the differences thus obtained may be considered as due to disturbances of all classes, but chiefly to intermittent disturbances. For this reason, the following results are distinguished from the former results, in terming them means of disturbances, instead of means of differences. Annual Variation of the Mean Disturbance.—The following are the SOs disturbances for a single observation of magnetic declination, in each month of 1844 :— Jan. Feb. March. April. May. June. July.

The sum of the positive disturbance is a minimum about 10" p.m.; it increases regularly from thence till about 9" 10™ a.m.; the interpolated maximum occurs about 10" a.m.; it then diminishes, after noon, with the previous regularity, till about 8 p.m. The sum of the negative disturbance, on the contrary, is a maximum about 10 p.m., and it becomes a minimum about 10" a.m.; the range of the positive sums is about a tenth less than the range of the negative sums. Lach of the two curves is irregular once in the 24 hours, and, curiously enough, this does not occur at the same time; the negative disturbance curve is irregular from 8¥ p.m. till 11" p.m., while the positive disturbance curve has nearly constant ordinates. On the contrary, the positive disturbance curve is irregular from about 9» a.m. till 1" p.m., while the regularity of the negative curve is most marked. The characteristics of these curves are therefore identical, when we consider the ordinates at 12 hours’ interval. It is obvious, then, that we have in the positive disturbance curve a simultaneous representative of the negative disturbance curve for our perici, the sign of motion with reference to space, or the sun, being the same for both. The result obtained for the year is also shewn, with considerable regularity, in the sums for each month. In the discussion of the total sums of differences, it appeared that the epochs of maximum and minimum varied with season. A consideration of the positive and negative portions, renders it probable that this variation is accidental; thus, though the minimum of the total sums of differences occurred, for the summer quarter, at 5 or 6” p.m., the positive disturbance has its maximum, for the same quarter, about 10 a.m., and its minimum about 10° p. mM. ., the reverse being true of the negative “disturbance, which is exactly the law of the sums from the whole observations of the year. Annual Variation of the number of Positive Disturbances—The following are the numbers per cent. of hourly observations in each month, which were positive, or to the west of the normal mean :— Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Noy. Dec. 515 55°83 59°8 49°5 51-1 52-2 455 5083 547 47:2 580 604 Taking the mean for each three months as the mean for the middle month— 55°7 55°5 54:9 53°5 90°9 49:6 495 50:3 50°9 53°38 552 566 From which it would appear, that the number of excursions to the west of the normal mean is a maximum at the winter solstice, and a minimum at the summer solstice. The reverse holds for the excursions to the east of the normal mean. In the year 1844, there were in 100 hourly observations of magnetic declination, 53 to the west and 47 to the east of the normal means. Diurnal Variation of the number of Positive Disturbances —The numbers per cent. for each hour, in 1844, which are to the west of their normal means, are— 12h jham. 2h gh. 4h, 5h Gh 7h Qh Qh JOh Th Qhibpm.

The following are the average — positive and negative excursions for each hour, together with the average of all the disturbances, without respect to sign :— Zz rf $129 145 1°51 153 1-75 1:85 1°93 1-92 1°93 210 1:97 1.85 186 1:76 186 1°76 1°53 1°36 1:20 1-02 0°89 0-84 0°98 085 — 2°31 2°16 1°95 1:68 1:52 1°30 0°94 0°91 0°82 0:90 0°82 0:92 1°02 0°94 1°06 1°44 1°41 1°54 2°56 2°50 3:07 2°66 2°50 2°87 — All, 1:91 1°88 1:74 1°60 1°62 1°58 1:50 1°50 1°54 1°73 1°59 1:52 1°60 1°48 1°56 1°63 1°48 1:45 1°90 1°81 2°23 1:90 1:92 208 12h lham, 2h 3h 4h 5h gh 7h gh gh Joh jh Ob ihpy, gh gh 4h 5h 6h 7h gh gh yoh qih y ‘ , ¢ , , , , ‘ , , , ¢ s , , , , , , , , , , MAGNETIC DECLINATION. 35] The average value of the excursions, therefore, varies considerably : the positive excursions from the nor- mal mean have their greatest average value about 9" a.m., and their least average value about 10" p.m., the least value being less than half the largest. The average negative excursion is least about 10” a.m., and greatest about 9 p.m (using the interpolated epoch), the least average being less than a third of the greatest. The least positive and negative averages have the same value, but the greatest negative average is fully a third greater than the greatest positive average. The average value of all the excursions from the normal mean is a maxi- mum (using interpolated epochs) between 9% and 10" p.m.; the time of minimum is not well marked; minima occur about 7 a.m. and 5" p.m., and there is the appearance of a secondary maximum about 9h a.m. The greatest average is to the least in the ratio of about 3 to 2. Probable Disturbance of Magnetic Declination.—In order to determine the probable disturbance for each hour of the day, Dr Luoyp has proposed to use the differences from the arithmetical means as errors in the ob- servations of a constant quantity, and to consider the square root of the mean of the squares of these differences, as the mean disturbance, corresponding to the mean error in the calculus of probabilities. It is obvious that the ordinary methods of the calculus of probabilities could not be employed if the probable error were con- sidered with reference to the normal mean, which is not the arithmetical mean ; considering the probable error, however, with reference to the arithmetical mean, it is certain from the foregoing conclusions that the distribu- tion of the individual differences or errors is not such as will satisfy the hypothesis of the observations of a con- stant quantity. The differences are not distributed equally, positively and negatively; nor is the difference from such a distribution constant: a new hypothesis for the mode of distribution would be requisite for each hour. Independently of this consideration, it will be found from the following results that the number of errors occurring within certain limits is not satisfied by the usual function of the errors obtained from the cal- culus of probabilities.

I have determined by a graphic interpolation the probable error of a single observation from the monthly mean for the corresponding hour, that is to say, I have determined approximately the error for which there are as many greater as there are less than itself.

In order to shew the difference of these values from those to be de- duced by the aid of the calculus of probabilities, we may obtain the latter with sufficient accuracy by means of the formula* Probable error = 0°845 x mean of errors, which formula gives the followimg values :— Jan.

From these values it appears that the probable error of a single observation from the monthly mean, for _ the corresponding hour (without reference to the month to which the observation belongs), is a minimum about — 54 a.m., and about 5" p.m., being, in both cases, rather less than a minute ; it is a principal maximum between ~ 9" and 10» p.m., being nearly a minute and a-half (15), and a secondary maximum about noon, being about ips; On the whole, it appears that, if it were required to make a single observation which should be as near to the monthly mean for the corresponding hour as possible, the observation should be made in June, and about — 5 a.m, or 5 p.m. When a greater number of observations are obtained, more accurate values for each hour in — each month may be found. Upon examining the distribution of the errors in the months of May, June, and July, 5” or 6" p.m. is found to be the hour of the smallest probable error in each month; the probable error at 5 — * ENOKE on “ The Method of Least Squares.” Taylor’s Scientific Memoirs, vol. ii., p. 355. MAGNETIC DECLINATION. 353 or 6" p.m. in June is only half a minute (05) ; about this hour, also, the numbers of positive differences and negative differences are nearly equal ; and since the mean of the observations at 6" p.m, in June is within half a minute of the monthly mean of all the observations, the probable error of a single observation in June 1844 at 6" p.m. would be only about 0’-5 from the mean declination for the month: a degree of accuracy which is quite equal to any thing that can be expected from a month’s observations with the best portable apparatus.

When the diurnal variation is considered in days nearly free from | intermittent disturbance, it is found that the minimum about 10" p.m. almost wholly disappears, and the mimi- mum about 6" a.m. is increased. Although, however, the 10" p.m. minimum and the secondary maximum — wholly disappear, the diurnal curve, even when unaffected by disturbance, does not become a regular curve of two branches ; on the contrary, there is still evidence of the action of a secondary or superposed cause of varia- — tion in the flattening of the curve from about 6" p.m. till about 2? a.m., in the sudden check in the rate of the © easterly progression about 6" p.m., and its sudden increase again about 2" a.m. These epochs, it will be observed, are the times of the principal minimum and maximum for our perieci. We might suppose the diur-— nal variation, therefore, when unaffected by intermittent disturbances, due to two operations of the same cause, — a direct action proper to one side of a zone producing a regular motion having its greatest westerly limit after — noon, and its most easterly limit about 6" a.m.; and an indirect or reflected action upon the opposite side of the same zone producing similar motions simultaneously, but of less magnitude. Such a hypothesis, which has — an analogy to that of tides (say in the atmosphere), would satisfy the simplest form of the diurnal curve for — the year, and for all the months for which the sun is north of the equator; another element perhaps requires — consideration for the winter months. a The form of the diurnal curve is different at different seasons of the year. Colonel Sapine has shewn, in his discussion of the St Helena Observations, that the diurnal curve has two opposite forms at St Helena, according as the sun is to the north or south of the equator ; the one corresponding to the diurnal motion for the northern hemisphere, the other to that for the southern hemisphere. An examination of the Makersiaai Observations will shew an equivalent fact. During the months that the sun is north of the equator the form and range of the diurnal curve have but little variation, but they change considerably in the months for which the sun is south of the equator. If we take the means of the 10 days of least disturbance in the two months HoRIZONTAL COMPONENT OF MAGNETIC FORCE. 355 of June and July as the most perfect representative of the diurnal curve at Makerstoun for the sun north of the equator, and compare this curve with that similarly obtained for the months of December and January when the sun is farthest south, we obtain the following variations corresponding to the differences of the hourly means for the two curves :— 12h lbam. 2h gh 4h = 65h 6h 7h gh gh 10h 11h oh Jhpy, 2h gh 4h 5h 6b Zh gh gh oh jh 3°43 4°12 4°22 5°00 5°69 7°12 7°89 7°77 6°85 5°56 447 2°29 132 040 0°00 0°16 144 2°09 2/39 221 2°09 2°39 2%54 3-09 It follows, therefore, that by the addition of the above quantities, representing the motion of the magnetic needle for the southern hemisphere, which has its maximum of westerly declination about 6" a.m., and its mini- mum about 2" p.m., to the quantities representing the diurnal motion for midsummer at Makerstoun, we obtain variations which represent the midwinter motion for the same place. The same result is obtained in the com- parison of the midsummer curve with that for November and February, and even for October and March, though with less accuracy as regards the epoch of minimum for the differences. It will be interesting to determine, from other observations, the latitude for which the midwinter curve ceases to have the characteristic of a northern curve. HORIZONTAL COMPONENT OF MAGNETIC FORCE.

Table XXII. has been formed from the daily means in scale divisions by the following formula :— f=(n— 500) 6:000140, where f is the mean in the Table, n is the mean in scale divisions, 500 scale divisions being taken as the zero ; the corresponding zero for the same adjustment in the end of 1843 was 484-93 ; in order, therefore, to render the means for 1844 comparable with those for 1843, 15:07 x 0:00014 = 0:002110 must be added to the former, 0°001000 being subtracted from the latter, and the differences multiplied by 1-316. See Introduction, Bifilar Magnetometer. The mean value of the horizontal component from Table XXII. = 0:0036085. Secular Change.—When the monthly means at the foot of Table XXII., and the monthly means for 1843 (as corrected, p. 231, line 6, 1843), are rendered comparable, as indicated after Table XXII., we have the following monthly means for the two years, with the corresponding secular changes :— Jan.

The mean secular change corresponding to 1st July 1843, till lst July 1844, . = +0-003886 A comparison of the mean value of the component for 1844, with that for 1845, shews that the amount of the secular change has continued to diminish, the mean corresponding to 1st July 1844, till 1st July 1845, being only +0:001436. As it is desirable, in some case, to eliminate the secular change in order to exhibit other laws with more distinctness, the mean of these two determinations has been taken as the secular change for 1844, or, The mean secular change corresponding to 1st January 1844, till 1st January 1845, . =+0-002661 This quantity is nearly the same as that obtained from a comparison of November and December 18438, _ January and February 1844 with November and December 1844, January and February 1845. Annual Period.—From the means at the foot of Table XXII., the horizontal component does not vary — greatly in value from January till April, but it increases rapidly from April till June, after which it is nearly constant again .till October, increasing again in November and December. It appears, therefore, that the secular — increase is neutralized for three months after the solstices, and augmented in the three months after the — equinoxes. In order to shew the law of the annual variation independent of the secular change, the latter has been eliminated from the means at the foot of Table XXII. by the application of the correction —n 0:000222, where n is the number of the month after January: the means, thus corrected, are— Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Nov. Dec. 0:00 | 2663 2623 2217 2810 2791 3815 3252 2822 2584 2346 2520 2770 These means exhibit the law already concluded from the observations for 1842 and 1843—namely, that the horizontal component is a minimum near the equinozes, and a maximum near the solstices. The secular increase 1s diminishing in value, and therefore the application of a constant correction from month to month cannot be quite accurate; any other mode of elimination, however, could only have affected the values of a ir maxima and minima ; the epochs would remain as stated above. It should be remarked, with respect to this law, that the variations of the magnetic dip are best repre- sented in this latitude by the bifilar magnetometer: this is not the case, however, in low latitudes ; in these, the variations of intensity are best represented in the horizontal component; if, therefore, the magnetic dip and magnetic intensity have each an equally well-marked annual period with different epochs, the same — HoRIZONTAL COMPONENT OF MAGNETIC FORCE. 357 instrument will indicate a different law in high and low latitudes.* See the discussion for the effect of disturbances on the monthly means for other considerations affecting the annual variation. Differences of the Daily Means from the Monthly Means.—The following are the average differences of the daily means from their corresponding monthly means :— Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Nov. Dec. 0-000 | 191 356 548 436 342 185 241 366 278 476 323 318 The daily means, therefore, differ least from the monthly means near the solstices, and most near the equinoxes, the average difierence for the latter being nearly three times that for the former. As in the case of the similar discussion for the declination, this law is also related to the annual period, and may be similarly generalized. The average difference of the daily mean from the monthly mean is a minimum when the _ horizontal component is a maximum, and vice versa. This correspondence is the more remarkable, since the epochs for the greatest and least average differences are not the same for the magnetic declination and horizontal component. The following are the averages of the positive and of the negative differences :— Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Nov.

Dr ILamonr has not been able to conclude any distinct law from the observations made at Munich (Resultate des magnetischen Observatoriums in Miinchen, 1843—1845, p. 28); this, it appears to me, is duc to the mode of discussion adopted. Dr LAMONT combines the monthly means into quarterly periods, January, February, and March being the first, a mode of combination the best fitted to disguise the law, since each period includes the whole range of the variations. Neglecting the means of the Munich Observations for 1842, which were broken up in May by MAG. AND MET. ozs. 1844. : 4x 358 RESULTS OF MAKERSTOUN OBSERVATIONS, 1844. Variation of the Horizontal Component with reference to the Moon’s Age.—This law is very distinctly marked in the means given in Table XXIII. The horizontal component of magnetic force is a minimum at opposition, and a maximum at conjunction. This will be more evident from the following means of groups :— 14 days to 16 days, Full Moon,............ 0000111 | 29 days to 1 oh New Dogon, 5.2, saeseee 0-:000564 Digi kU) awe: 0:000090 | 2 ...... 5 0000561 Ps eae 24... 0;000339)), 6 ......

Lowe. 0:000081 An examination of the daily means of the horizontal component shews, that this law is indicated with great distinctness in seven or eight lunations of 1844,—namely, in the lunations between January 5 and — April 3, and between August 2 and December 20. The law is distorted or exaggerated in some lunations by the larger disturbances. In all probability, the mean range is exaggerated by the larger negative dis- turbances which appear to have occurred about full Moon in 1844. Variations of the Horizontal Component with reference to the Moon's Declination.—This law is also well marked in the means in Table XXIII. The horizontal component is a maximum when the moon has its greatest north, and also its greatest south declination; and it is a minimum between these epochs, when the moon is rather north of the equator. The following are means of groups :— 27 days to 1 day, Moon farthest north,...0:000441 13 days to 15 days, Moon farthest south, 0:000477 ie, far 5 days 0000326) 16 ...... 19 0°000426 Oe anaes: cee 0:000193 | 20 ......

Annual Variation of the Diurnal Ranges of the Horizontal Component.—The following are the monthly means of the diurnal ranges :— Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Noven Wec. 0:00 | 1920 2750 4980 4990 4510 38710 4290 4600 4020 3690 3140 2510 The diurnal range is therefore a minimum in January, a secondary minimum in June, a maximum in ~ April, and in August; or generally, it is a minimum near the solstices, and a maximum immediately after the - vernal and before the autumnal equinox. In the annual variations, therefore, it appears that when the horizontal component is a maximum, the diurnal range is a minimum, and vice versa. ’ The mean of the diurnal ranges for the year = 0:003760. When the means of the diurnal ranges are compared with the ranges of the mean diurnal variations (see p. 363), we obtain the following excesses of the former compared with the latter :— Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Nov. Dec. 0:00 | 1230 1675 2785 1612 0866 0531 0633 1099 1074 1377 1835 1750 Whence it appears, that the causes which render the mean diurnal range greater than the range of the mean diurnal variation, have their minimum effect in June, a secondary minimum being in January; their — maximum in March, and a secondary maximum in November. This is the same result as that already — obtained for the magnetic declination. some instrumental causes, and considering the means for the last three years, commencing December 1842, we have the following quantities (Resultate, p. 77) :— Dec. Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Nov. 1:93 | 657 633 637 663 653 750 760 783 770 677 710 780 These means include the secular change, and they follow nearly the same law of variation as the means at the foot of Tabl XXII. ; in fact, an examination of the above quantities will shew that any elimination of secular change which is near the truth wi give the law as already stated. Taking the mean secular change from 1843—1845 = 0-0018 a-year (Resultate, p: 27), and reducing the values to December at the rate of 0:00015 a-month, we obtain the following means :— Dec. Jan. Feb. March. April. May. June, July. Aug. Sept. Oct. Noy. » 1:93 | 657 618 607 618 593 675 670 678 650 542 560 615 r These appear to give a sufficiently distinct result; the horizontal component is a maximum in December and in June (May, — June, and July having nearly the same value), and it is a minimum in April, and a principal minimum in September. This seems — nearer to the results of the Makerstoun Observations than could be hoped for, when we consider the difference of instruments (D Lamont’s having a unifilar, and the Makerstoun instrument having a bifilar suspension), and the consequent liabilities to differen kinds of instrumental error.

Variations of the Diurnal Ranges of the Horizontal Component, with reference to the Moon's Age-—The means in the first portion of Table XXV. shew that the diurnal range of the horizontal component is a minimum about conjunction, and a maximum about opposition. The same result has already been obtained for the mag- netic declination. The following are means of groups :— 14 days to 16 days, Full Moon, 0-004710 29 days to 1 oe New Moon, 0:003436 Bete as Pd ea 0°004235 2, cee 3) 0:003058 Dil: arated 24... 0:003127 Gy.) ta ONS 0-003874 Do. ats po aae 0:002936 TO), sacaee US ..-.0 0:004982 There is the appearance of a secondary maximum at new moon, The remarks already made in the case of the magnetic declination, Table IV., are equally applicable here. In the case of this period, as well as that for the year, it appears that the diurnal range is a maximum when the horizontal component is a minimum, and vice versa. Variations of the Diurnal Range of the Horizontal Component with reference to the Moon’s Declination.— From the second portion of Table XXV., the diurnal range is a minimum when the moon has its greatest south and also its greatest north declination, and it is a maximum when the moon is near to, but north of, the equator. This result is also the same as that obtained for the magnetic declination. The following are means of groups :— wh days to 1 day, Moon farthest north, 0°003267 | s days to 15 a Moon farthest south, 0:003248 | secstaek 5 poe ae. 0:004481 BG 0:003546 : bor Sine 8 0-004115 a cee a2: 0:003682 Sheree de sists 0:003401 | 23 ...... DO lar. 0:0043811 Here, also, as for the magnetic declination, we can say generally, that the diurnal range of the horizontal component of magnetic force is less when the sun or moon has its greatest north or south declination, than at the intermediate periods. In this case, also, the diurnal range is a maximum when the horizontal component is a Minimum, and vice versa.

An examination of the monthly means will shew, that the two maxima and the two minima are each of nearly equal value in the winter months, the morning _ maximum being the principal maximum in the month of December; in the summer months, on the contrary, the secondary maximum and minimum nearly or altogether disappear. There are several irregularities, especially in the autumnal and winter months, which are evidently due to disturbances. The following are the approximate times of the principal mmimum (—) and maximum (+), and of the secondary minimum and maximum :— Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Nov. Dec.

The same epochs are obtained from the mean for the 120 days; in this case, however, the secondary minimum is better marked. The secondary minimum and maximum are distinctly marked in the _ mean of the whole observations; they are still existent in the mean for the 120 days least disturbed, and scarcely evident in the mean of the 60 days least disturbed; in a more careful selection, therefore, it is probable that they would wholly disappear. This case is completely similar to that for the secondary maximum of the magnetic declination ; and in this case, also, there is still a marked inflexion, which, however, can be at once traced to the duplicate form of the diurnal variation in the winter months. The following Table contains the approximate times of maximum and minimum for each month.

On the whole, the principal maximum occurs earlier in the mean for the whole series, than in the means for the selected series—the effect of disturbances, therefore, being to accelerate the epoch of maximum. In all the three series there appear to be three maxima and three minima in the month of February, and these are | most distinctly marked in the least disturbed,—the five-day series. These, and other more minute characteris- | ties, will be better considered in connection with the discussion of the succeeding year’s observations. Intermittent disturbances seem to have less effect on the form of the diurnal variation of the horizontal porn (and therefore, probably, the dip), than on the form of the variation for any of the other elements | discussed.

Diurnal Variation of the Horizontal Component with reference to the Moon's Hour-Angle.—In this case, as in that for the magnetic declination, the means for the lunations in winter give a somewhat different law from those for the lunations in summer. The following are the means at nearly two-hourly intervals for the summer and winter groups, and for the whole twelve lunations :— Groups, ObOm Qh25m 4hQom Gh]5m Sb]Om JOh5m 1QhOm 13h H5m 15h 50m 17h 45m 19h 40m Q]h Bom Winter;...0:000| 066 000 073 086 186 096 254 281 131 215 197 104 Summer, 0:000|155 147 144 098 O66 114 212 283 156 073 000 070 Year 1844, In the winter group, for which the moon is in opposition north of the equator— } 0:000|037 000 035 019 028 033 -160 184 070 070 025 012 The maximum occurs about 2 hours after the moon’s inferior transit.

There are appearances of minima before and after the latter epoch, but they are not distinct. The variation for the year, therefore, has the same epochs as that for the winter group. As the range of this variation is so small, it was supposed that the large disturbances might have considerable effect in destroying its regularity. In order to test this, all those observations which differed more than 25 scale divisions (00035) from the monthly means for the corresponding hours, were rejected in the summations, quantities interpolated from the preceding and succeeding observations having ‘been substituted. The following are the resulting variations at nearly two hourly intervals :— ObOm QhQ5m 4h Qom Gh]5m Bb JOm Oh Hm JQhOm JBb 55m 15h 50m 17) 45m 19h 40m 21h B5m rea, } 0°00 | 047 053 101 055 076 074 164 187 059 078 000 O71 These give the same time of maximum, but the minimum occurs four hours before the superior transit, instead of after it; a secondary minimum also occurs about seven hours after the superior transit,—a secondary maximum occurring between the two latter epochs. The elimination of those observations affected by large irregularities renders the variation for the year analogous, in its smmgular points, to that for the summer months given previously; it is quite possible, therefore, that the differences between the law of variation for the summer and winter groups may be due chiefly to intermittent disturbances. INTERMITTENT DISTURBANCES. Effect of Intermittent Disturbances on the Yearly Mean of the Horizontal Component.—Performing discussions for the horizontal component of magnetic force similar to those already made for the magnetic declination (p. 343), we obtain the following results :— Mean of the horizontal component for 1844, as deduced from 120-day series of hourly observations, greater than that deduced from the whole series by ............ Mean of the horizontal component for 1844, as deduced from 60- oe series hai 0-000251 hourly observations, greater than that deduced from the whole series by ............ } 0-000189 Hence the effect of disturbances in 1844, was to diminish the mean value of the horizontal component of force; the mean for the 60-day series of observations being greatest, 0-000062 greater than that of the 120- day series, and 0:000251 greater than that for the complete series. Effect of Disturbances on the Monthly Means of the Horizontal Component.—The corrections of the means from the 10 days and 5 days selected in each month to the means from the complete series, are, in scale divisions, as follow :-— ec Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Noy. Dec. 10 days,— 0°78 —2:47 —2:85 —2:25 —0-21 +0:13 —0-:15 —0:77 —0-44 —3-62 —1:17 —1-67 5 days, —1:06 —2-°93 —3-75 —2:93 —0-96 +0-82 +001 —0:97 —1:11 —4:08 —2-44 —2-11 The corrections for both series give the same result; but it is most marked for the 5-day series, that least affected by disturbances. This result may be stated as follows:—The effect of disturbances is to diminish the monthly mean of the horizontal component in all cases, with the exception of that for June, and, | perhaps, July; the diminution is greatest near the equinoxes, and least at the solstices; at the summer _ solstice the effect is to increase the monthly mean. When we compare this result with that already given for the annual period (see p. 356), we might be induced to conclude that the latter is due to disturbances: this, however, is not the case. If we apply the above corrections reduced to parts of force, to the monthly means, MAG. AND MET. oBs. 1844. 47 366 RESULTS OF THE MAKERSTOUN OBSERVATIONS, 1844. p. 356, for which the secular change has been eliminated, we obtain the following quantities, which are the monthly means of the 10 days and 5 days, with the secular change eliminated :— Jan.

We have therefore the same law of annual period as from the complete series of observations, namely, maxima near the solstices, and minima near the equinoxes. An examination of the days which have been selected as most free from disturbances has shewn, that these days are generally near the time of new moon; at which time, according to the previous discussion, p. 358, the horizontal component has its greatest value, and in accordance with a discussion which follows, p. 369, at which time magnetic disturbances are a minimum. Though no elimination of disturbances will destroy the annual variation of the horizontal component, it is evident, for 1844 at least, that disturbances increase its amount, and it will be a question to be decided by a more extensive induction, whether the annual variation be not due to a regular action of the cause producing the disturbances.

It will be perceived that the epochs for the effect of disturbance on the horizontal component, are considerably different from those for the magnetic declination: the effect on the latter is zero when the effect on the former is a maximum, and vice versa. The maximum effect of disturbance in diminishing the horizontal component, occurs about two or three hours after the corresponding epoch for the magnetic declination, the time for the latter bemg about 10 p.m. The greatest effects of disturbance in increasing and diminishing the hourly mean of the horizontal component, as deduced from the comparison of the whole series with the 60-day series of observations, are as follow, the whole horizontal component being unity :— Maximum effect in increasing the horizontal component (4° 10™ p.m.) ............... ogres =0-000300 ch sevens diminishing "7s. sscceeeeeees-------2.--) (LI*10™ pam. and‘2?'10™ a.w.)=0°000228 The effect of disturbances on the hourly means of the horizontal component is therefore less in compari- son with the diurnal range, than in the case of the magnetic declination ; in the latter case the maximum effect is between } and } of the range of the mean diurnal variation, whereas in the case of the horizontal component it is only between + and 3 of the diurnal range. An examination of the differences for each month, will shew that the law is somewhat variable; the secondary maximum about 6" a.m., and minimum about 10" a.m, are most distinct in some months, especially in the winter. 368 RESULTS OF THE MAKERSTOUN OBSERVATIONS, 1844.

Differences of the Individual Observations from the Monthly Means for the corresponding hours.— Adopting the process already indicated, p. 346, for the magnetic declination, we obtain the following Table :— TABLE XXXIV.—Mean Difference of a Single Observation of the Bifllar Magnetometer from the Monthly Mean, at the corresponding hour, for each Civil Day and Week in 1844.

The maximum disturbance of the horizontal component occurs near the equinoxes, and the minimum disturbance occurs near the solstices. While the effect of disturbances on the hourly means is less for the horizontal component than for the magnetic declination, the individual observations of the former differ more from the corresponding monthly means than for the latter, the diurnal range in each case being the standard of comparison.

Variations of the Mean Differences with reference to the Moon's Declination.—A general examination of the second portion of Table XX XV. shews that the average diflerence of a single observation from its corre- sponding monthly mean is a maximum twice, namely, when the moon is about two days north of the equator, and that it is a minimum twice, namely, when the moon is farthest north and farthest south.

Feb. March. April. KH OMNoaonNauehwnro* — Diurnal Variation of the Mean Difference—The mean difference is a maximum twice and a minimum twice in the day, in the variations for the year. The greatest mean occurs at 9" 10™ p.m., but the greatest mean of two consecutive hours is that for 4" and 5" p.m.: the interpolated epochs are as follow: maxima at 45 40™ HorIZONTAL COMPONENT OF MAGNETIC FORCE. 371 p.M., and at 10" 10™ a.m.; minima at 6" 30™ a.m., and at 1" 40™p.m. Although the greatest value occurs about 4" 40™ p.m., the mean difference varies little from 4" 10™ p.m. till 22> 10™ a.m. The following are the approximate epochs of maxima and minima of the diurnal variation in each of the astronomical quarters of the year :— Nov., Dec., Jan., Min. 6° am.

The laws of variation in three quarters bear a considerable resemblance to each other, and to that for the year, namely, winter, spring, and autumn; in these quarters the minima occur about 5 a.m. and 2 P.M. ; one maximum occurs in all about 10% a.m., the other occurs in two about 6" p.m., but in spring it is about 1” Am. The variation for summer differs most from the others; there is but one maximum and one minimum. Much of these differences may be due to the fewness of the observations upon which the law depends. Annual Variation of the number of Positive Differences.—The following are the numbers of differences in 100 which were positive :—- Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Nov. Dec.

The number of positive differences was less than the number of negative differences in the months of June, July, and August, but greater in the other nine months ; and in the year there were nearly 54 positive to 46 negative observations. , Diurnal Variation of the number of Positive Differences—The number of positive differences in 100 for each hour of Makerstoun mean time in 1844 are as follow :— 12h Tham. 9h 3b 4h 5h gh 7h gh gh oh qh Qh ybpy, gh gh gh 5h Gh 7h gh gh 40h yh 545 56:7 58:6 58:0 57-0 58:9 51:0 53:2 51:6 55:4 59°6 56:1 52:2 50°3 516 48-1 47-1 49:4 48:7 54:8 49°4 57-0 55-4 57-3 The number of positive differences is a maximum about 4" a.m. and 10" a.m.; it is a principal minimum about 4 p.m. and a secondary minimum about 74 a.m. The number of positive differences is greater than the _ number of negative differences in each hour, excepting those from 3? till 7”. Mean Disturbance. 4 Making use of the means deduced from the five days least disturbed (Table XXIX.) as approximate nor- _ mal means, as has been already done for the magnetic declination, pages 349 and 350, we obtain the following _ results. Annual Variation of the Mean Disturbance.—The following are the mean disturbances for a single obser- vation in parts of the horizontal component in each month of 1844 :— . Jan. Feb. March. April.

The sums of negative disturbances are a minimum about 3510™ p.m., and a maximum about midnight; they are a secondary minimum at 6" 10™ a.m., and a maximum at 10 10™ a.m. On the whole, therefore, the epochs of maximum for the positive disturbancearewithin an hour of those of minimum for the negative disturbance, and vice versa.

In the year 1844, there were, in 100 observations, 54:5 greater and 45:5 less than the normal means at the corresponding hours. ' Diurnal Variation of the numbers of Positive Disturbances.—The numbers per cent. of hourly observations which were greater than the monthly means at the corresponding hours, are as follow :— 12hibam, 2b gh 4h 5h 6h 7h gh gh 10h ih ob ihpm, 2h gh 4h 5h 6b 7h gh gh 10h 11h 47-5 47°8 44:9 50:3 51°6 58:9 55:4 55:1 554 53:5 54:1 59:2 605 57°6 63:4 59:9 67-2 64-0 58°9 57-3 53:8 46°56 52°5 46°5 The number of positive disturbances is a maximum at 4" p.m., and a minimum about 2" a.m.; there is the appearance of a secondary maximum at 5" a.m., and minimum at 9" 30™ a.m. From about 9" p.m. till 2h am., the number of positive disturbances is less than the number of negative disturbances; at all the other hours of the day the number of positive disturbances is greatest. There are nearly two positive disturbances — ; for one negative disturbance at 4° p.m. Diurnal Variation of the Positive and Negative means of Disturbance.—A comparison of the diurnal laws of variation for the swms and numbers of positive disturbances, will shew that they give nearly the same epochs of maxima and minima; it is uncertain, therefore, whether the variation of the sums depends solely or chiefly on the variation of the numbers of disturbances which are positive or negative. The following are the mean values, in scale divisions, of the positive and negative disturbances for each hour, obtained by dividing the sums of the positive disturbances by their number, and the sums of the negative disturbances by their number :-— 12h jham, gh 3h 4h 5h 6 7h gh gh Joh 11h 19h jhp,m, Qh sh 64h 5h gh 7h. gh gh joh yh 4+3°32 2:83 2:94 2°85 2:98 3°63 3°82 3:39 3°65 3°72 3:64 3:96 4:62 4:19 4:16 5:05 5:17 5:00 4:55 4:03 4:05 3:35 3:05 2-91 —5:11 5-16 5:34 4°80 4:17 5°52 3:72 4:38 4:96 5:08 5:39 4:78 4:20 3:58 3°71 4:06 4:02 4:23 4:17 4:72 4°38 5:48 5-42 5-60 These values differ considerably ; the law of their variation is almost exactly that already obtained for the sums of positive and negative disturbance.

Die Note on the least probable error of an observation of the horizontal component of magnetic force.— Investigations for the probable errors of observation corresponding to those for the magnetic declination, have not been made for the horizontal component; it will not be difficult, however, to approximate to the least probable errors of an observation from the values of the mean difference. The mean difference of an observation is least in the month of January, and in the months of June and July, being 0:00035, 0:00040, and 0-00047, for the three months respectively; which, if the distribution of the errors follows nearly the same law as that found for the magnetie declination, will give probable errors of about 0-00024, 0-00027, and 0:00032, of the horizontal component. The mean difference, for the year, of an observation of the horizontal component, is a minimum about 6" a.m., and 15 and 2" p.w., being about 0:00050; the probable error is about 0-00034. In order that an observation of the horizontal component should have the least probable error, it should be made in the months of January, June, or July—and early in the morning. about 2 a.m. in these three months, being less than two ten-thousandths of the whole horizontal component. The least probable errors are VERTICAL COMPONENT OF MAGNneric Force. MAG. AND MET.

The balance-needle was removed on the 27th January 1844, for the purpose of determining its temperature coefficient ; it was readjusted on the evening of the same day; all the observations before that date have been rendered comparable with those after it by the application of a correction.—See Introduction. In order to render the means in Table XV., p. 238, 1843, comparable with the means in the preceding Table, the following formula must be employed :— uv + c 0-00223. oom ¥= Where V is the reduced value of the mean for 1843, uv is the value in Table XV., 1843; ¢ is the correction for the mean of 9 observations to the mean of 24 observations, as given, line 6 from foot of page 240, 1843; 223 micrometer divisions being the difference of the zeros for 1843 and 1844, The mean value of the variations of the vertical component, from Table XXX VIII.=0:006781.

These epochs are, on the whole, VERTICAL COMPONENT OF MAGNETIC FORCE. 375 not much different from those for the anuual period, as deduced from the observations in 1844; and the result might be stated in the manner already done for the horizontal component and magnetic declination. The average difference of the daily means is a maximum when the vertical component is a maximum, and vice versa. In the case of the horizontal component, the average difference was a maximum when the horizontal component was a minimum. The following are the averages of the positive and negative differences :— Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Nov.

The form of the diurnal variation of the vertical component varies more with season than that of the diurnal variation for either of the elements already discussed. In winter the diurnal variation is single, the mini- mum occurring about 55 a.m. and the maximum about 6" p.m. In the months near the equinoxes the range of the variation is greatly increased, and its form is similar to that for the year given above; the secondary maximum and minimum become gradually more marked as the epoch approaches the summer solstice, till in the months of June and July the principal minimum occurs about noon, the range of the diurnal variation hav- ing diminished at the same time to nearly the same value as at the winter solstice.

The principal maximum occurs earliest at the equinoxes: the principal minimum occurs farthest from midnight at the winter solstice and nearest it as we approach the summer solstice. The principal minimum actually occurs near noon at the summer solstice, but the minimum near midnight differs little in value. Adopting the method already pursued (see page 339) for the purpose of considering the diurnal variation when freed as far as possible from the effects of irregular causes, the following Tables have been formed.

Considering at first the mean of the 60 days representing the mean for the year, free or nearly free from intermittent disturbances, we find that the diurnal variation consists of two nearly equal maxima and two nearly equal minima; the principal of the former occurs at 4" 10™ p.m. and the other at 8? 10™ a.m., while the principal minimum occurs at noon and the secondary minimum at 1" 10™ a.m. The mean for the 120 days differs from that for the 60 days, only in placing the principal maximum an hour later, namely, at 5" 10™ p.m, The effect of the intermittent disturbances therefore is nearly to efface what is really the principal minimum and to exaggerate what is only a secondary minimum ; the range of the mean diurnal variation when freed from the effect of disturbances is little more than a fourth of that obtained from the whole series of observations When the non-disturbed variations for the different months are examined, it is at once apparent that the matters which have been noted as remarkable in the total results are chiefly or altogether due to disturbances ; in fact, the diurnal variation consists in the eight months from March till October of two maxima and two minima, and resembles generally the result for the year, the earlier maximum being at times the principal. The variation in the four winter months differs somewhat from that for the other months, being more like a single variation; there are, however, some differences which may be accidental, but which will be considered in connection with the observations for 1845. The following Table contains the approximate epochs of the singular points for each month, the principal are indicated by + and — VERTICAL COMPONENT OF MAGNETIC FORCE. 381 TABLE XLVI.—Epochs of Diurnal Maxima and Minima of the Vertical Component of Magnetic Force, obtained from the selected series of observations, 1844. 10-Day Series. 5-Day Series.

The epochs for the 10-day series are the most consistent, 5 days are pro- bably too few for consistent results, especially in the present case, where the days were selected chiefly as being free from irregularities for the magnetic declination. Ranges .of the Mean Diurnal Variations——The following are the ranges of the monthly mean diurnal variations, as deduced from all the hourly observations, and from the hourly observations on the 10 days and on the 5 days selected as least affected by disturbances :— Jan.

When we consider the range of the diurnal variation nearly unaffected by intermittent disturbances, as deduced from 10 - days selected, we find a totally different result, as in the case of the other elements discussed the diurnal range has a nearly constant value during the months for which the sun is north of the equator. The excess, | therefore, of the range at the equinoxes from all the observations, is due solely to disturbances, which, as has | been shewn in the previous discussions, are a maximum at these epochs. The ranges from the 5 days selected are perhaps less accurate, owing to the fewness of the observations from which they are obtained. MAG.

In the winter group, the maximum of the vertical component occurs about 24 hours after the moon’s transit of the inferior meridian, and the minimum about 3 hours after its transit of the superior meridian. In the summer group, there are two maxima and two minima; the principal minimum oceurs 4 hours — before the moon’s inferior transit, and the principal maximum occurs 4} hours after the inferior transit; a secondary minimum occurs about 43 hours before the superior transit, and a secondary maximum at the superior transit. In the mean of the 12 lunations in 1844, the maximum occurs 33 hours after the inferior transit, and the minimum occurs 7 hours after the superior transit. There is a secondary maximum immediately before this epoch, but it is not well marked. The remarks already made for the similar discussion of the horizontal component also apply here. In order to eliminate the effect of disturbances, those observations were rejected in the summations, which were considerably disturbed, differmg from the monthly means at the corresponding hours by more than 50 micrometer divisions (=0-000500), quantities interpolated from the preceding an succeeding observations having been substituted. The following are the resulting variations at intervals of 34 of an hour:— 0 1 2 8 4 8 6 ¥ @ 9 (Spal 12 18 14°95 Ge Go as 19 20) 20 oe 0:0000 | 87 31 29 22 17 20 06 00 04 12 24 32 47 59 73 77 83 70 58 43 40 39 34 39 36 The maximum occurs about 2 hours after the moon’s passage of the inferior meridian, and the minim 7 hours after the superior transit; there is an ill-defined mimimum about 3 hours before the superior transit and maximum at the superior transit. = VERTICAL COMPONENT OF MAGNETIC FORCE. 383 TABLE XLVIII.—Differences between the Hourly Means of Balance Micrometer Readings for the whole series in each Month, and those for the selected Ten Days; or Table XLII. minus Table XLIV. ones Jan.

INTERMITTENT DISTURBANCES. Effect of Intermittent Disturbances on the Yearly Mean of the Vertical Component.—Performing discussions similar to those already made for the magnetic declination and horizontal component, we find the means of the vertical component as deduced from different series of days as follow, the value at 0 micrometer divisions being unity :— Mean vertical component for 1844, as deduced from the 120 days, greater than that from the whole series by 0:000021 Jarataeinids siavasUldeonehis cit tonere caeeea Rest te ese nee eae a ee eee (510) Gasobppargbenpeanco: curdnosoccastagaascasnonca Ghosggoss son 0:0G0015 The effect of disturbances, therefore, in 1844, was to diminish the mean value of the vertical component, as well as of the horizontal component. Effect of Disturbances on the Monthly Means of the Vertical Component.—The corrections of the means from the 10-day and 5-day series selected in each month, to those from the complete series, are, in micrometer divisions, as follow :— Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Nov.

Effect of Disturbances on the Hourly Means of the Vertical Component. —Considering, first, the differences of the hourly means for the year, as obtained from a comparison of the whole series with the 60-day series of observations (see last column of Table XLIX.), we obtain the following results :— The mean effect of disturbances upon the hourly means of the vertical component, is a positive maximum at 5° 30™ p.m.; it is a negative maximum about 2? a.m., and it is zero at 10" a.m., and near 10" p.m. The comparison of the whole series with the 120-day series (see last column of Table XLVIII.) gives exactly the same result. The times for the maximum effect of disturbance on the hourly means of the vertical component, are about 13 hours after those for the horizontal component. The greatest effects of disturbance in increasing and diminishing the hourly means of the vertical compo- nent for the year 1844, as deduced from the comparisons with the 60-day series of observations, are as follow: Maximum effect in increasing the vertical component (5" 30™ P.M.)...............004- =0-000196 RA erie ors chat eee diminishing’... ueeseemeseteeee-<. (2!

The maximum positive effect oceurs about 53> p.m., and the maximum negative about 1" s.m.; whence, as in the analogous discussions for the magnetic declination and horizontal component, we may conclude that the smallest and largest disturbances obey the same diurnal law. (See pp. 345 and 368.) Differences of the Individual Observations from the Monthly Means for the Corresponding Hours.—Adopting the process already indicated for the magnetic declination, p. 346, we obtain the following Table :— TABLE L.—Mean Difference of a Single Observation of the Balance Magnetometer from the Monthly ; Mean, at the corresponding hour, for each Civil Day and Week in 1844.

Mean Disturbance. Deducing the differences by using the means obtained from the 5 days least disturbed, Table XLV., in the manner already done for the declination, pages 349 and 350, we obtain the following results :— Annual Variation of the Mean Disturbance.—The following are the mean disturbances, in micrometer divisions, for a single observation of the vertical component in each month of 1844 :— Jan.

The mean disturbance of the vertical component is a2 minimum at 10° a.m.; it is a maximum at 5440™p.m.; a secondary minimum occurs at 95 10™ p.m., and a secondary maximum about 2" a.m.,—the value of the disturbance varying little from midnight till 55 a.m. Annual Variation of the number of Positive Disturbances.—The numbers per cent. of hourly observations in each month, which were greater than the normal means for the corresponding hours, are as follow :— Jan.

In the year 1844, there were, in 100 observations, 52 greater and 48 less than the normal means at the corresponding hours. Diurnal Variation of the number of Positive Disturbances—The numbers per cent. of hourly observations _ which were greater than the monthly means at the corresponding hours, as deduced from the 5-day series, are as follow :-— igh yhaw, gh gh gh 5h gh 7h gh gh gh yah oh Yhpap, gh gh 4h «gh gh Ths gh gh, qgh_ qh 38:3 37-7 39-0 40°3 39°3 40°6 40°6 42°8 40-3 40:6 50°8 55:3 57-2 61:7 64:5 63:9 67:1 70:6 68-7 69:3 67:4 60:1 47-9 41:5 The number of positive disturbances is a maximum about 5" p.m., and a minimum about 12 a.m. The reverse, of course, holds for the numbers of negative disturbances; they are a maximum about 1" a.m., and a minimum about 5" p.m. Since the numbers of positive and negative disturbances have the same epochs of maximum and minimum as their sums, it may be still a question whether the mean positive and negative disturbance obeys the same law.

The mean difference, however, for an observation of the vertical component is least for the months of December and January, when it is 12°3 micrometer divisions, and for the months of June and July, when it is 14:0 micrometer divisions.

The probable error of an observation of the vertical component from the monthly mean for the corresponding hour will therefore be in eee ae - lamina Wii: Sc0bi0:, of the whole component. These values are estimated from a consideration of the results for the declination, p. 352. The mean difference of an observation is least at 10" a.m., being 11°6 micrometer divisions, when the mean for the whole year is considered. The probable error of an observation from the monthly mean for the corresponding hour, without reference to which month, will be less than 0:00008 of the whole vertical component. Maeyetic Dip.

Secular Change of Magnetic Dip.—This deduced from the mean secular changes for the two components, pages 356 and 374, = —6"1. It is very probable that this change is considerably too great, and therefore that the secular change for one or both components is also in error, or is due to instrumental causes.

This result differs somewhat from the result obtained from the observations for 1848 (p. 248) ; this is obviously due to the difference in the results for the vertical component in the two years.

Diurnal Variation of Magnetic Dip—In the mean for the year the magnetic dip is a maximum at 10" 10™ a.m.; it has its least value at 54 10™ p.m., but the value differs little from 5° till 8° p.m.; it has a secondary maximum at 2" 10™ a.m., and a secondary minimum at 5° 10™ a.m. The increase is most rapid from 6" a.m. till 10" a.m., and the diminution is most rapid from 10" a.m. till 5" p.m. In the four months of May, June, July, and August, the secondary maximum and minimum are not at all visible; in the four equinoctial months the variation is very irregular from about 5” p.m. till about 5® a.m., the dip oscillating about a nearly constant value; in the four winter months the secondary becomes the prin- cipal maximum, the maximum at 5" nearly disappearing in December. The principal minimum always occurs about 10° a.m. The range of the mean diurnal variation of magnetic dip for the year =2’-04 We might proceed to consider the diurnal variation, as obtained from the selected series of 10 days and 5 days in each month, but this will be done with more accuracy in connection with another year’s observations ; at present it will be enough to give the variation for the year, as deduced from the 120-day and 60-day series. The variations for these series, deduced from the last columns of Tables XX VIII., XXIX,, XLIV., and XLV., and reduced so that the mean is equal to the mean of the last column of Table LV., are as follow :— 12h jham, Qh gh 4h 5h 6h Th gh gh Joh Jib Ob jhpm 2h gh 4h 5h 6h 7h gh 9h Joh 41h Series. / , ¢ i , “p / , ‘ / ‘ , fd , / , , ‘ey ‘ , 7 id 7 / 120-day, 0°54 0°60 0°66 0°71 0-69 0.68 0°81 1°02 1°46 1°83 1:98 1°71 1:28 0°74 0°47 0°28 0°24 0:07 —0°04 —0°05 0°05 0°15 0°21 0:29 60-day, 0°48 0°54 0°61 0°66 0°68 0°69 0°83 1:02 1°49 1°84 1°96 1°76 1°30 0°76 0°49 0°34 0°29 0°04 —0°03 —0°04 O01 Or11l 0°24 0°30 The means for both series give the same result ; the maximum of dip occurs at 10" a.m., and the minimum at 6" 40™ p.m.: the secondary maximum and minimum are not exhibited in these variations ; the dip, however, has nearly a constant value from 2? till 5" a.m. The results for the selected series, which are nearly unaffected by intermittent disturbances, place the principal minimum an hour and a-half later than the result for the whole series, and the removal of the disturbances seems nearly to obliterate the secondary maximum and minimum in the diurnal variation. The range of the mean diurnal variation for the year from all the three series is slightly above 2’, which is equivalent to a variation of 6’ of magnetic declination; the range of the diurnal variation of magnetic declination for the year being 7-7, the motion in declination is rather greater than that in dip at Makerstoun. Ranges of the Mean Diurnal Variation of Magnetic Dip.—The ranges of the mean diurnal variation for each month, as deduced from the whole series of observations, are as follow :— Jan. Feb.‘ March. April. May. June. July. Aug. Sept. Oct. Nov. Dec. 0-78. O°82. 2°12 3°19 s’49 3°28 3:60 334 2°86 2°44 Iso These quantities follow the same law as that already obtained for the horizontal component. The range of magnetic dip is a minimum, and has a nearly constant value, in the three winter months, December, January, and February ; the range for November is exaggerated by intermittent disturbances. The range is a maximum, and is nearly constant in the months of April, May, June, July, and August. When the ranges of magnetic declination are reduced to their equivalent motions, as shewn by a needle freely suspended in the direction of magnetic dip, it will be found that the vertical motion is greater than the horizontal motion in May and July, that the amounts of the two motions differ little in the months for which the sun is north of the equator, and that in the months for which it is south of the equator the horizontal motions are considerably greater than the vertical motions.

O18 In the winter group— The principal maximum of dip occurs about 4 hours after the moon’s inferior transit. The principal minimum occurs 4 hours before and at the inferior transit. A secondary maximum occurs about 2 hours after the superior transit. A secondary minimum occurs about 6 hours before the superior transit. There is a secondary maximum 2 hours before the inferior transit, which is perhaps accidental, In the summer group the law of variation is most distinct— The principal maximum occurs 4 hours before the moon’s superior transit. The principal minimum occurs about 2 hours after the inferior transit, The secondary maximum occurs about 4 hours before the inferior transit. The secondary minimum occurs about 3 hours after the superior transit. In the mean for the year the secondary maximum and minimum are not well marked— The principal maximum occurs about 6 hours after the inferior transit. The principal minimum occurs about 1 hour after the inferior transit. The secondary maximum occurs about 2 hours before the inferior transit. The secondary minimum occurs about 6 hours before the inferior transit, The whole range of these variations is very small, the greatest range is that for the summer group, which is 04, this however is equivalent to a range of 1-2 for the declination: if we examine the similar discussion for the magnetic declination, p. 342, it will be seen that the greatest range is that for the winter group, which is 15; so that the diurnal range of the variation due to the moon is nearly the same for the magnetic declina- tion in winter as it is for the magnetic dip in summer. If we determine the variations from those for the horizontal and vertical components after Tables XXXI. and XLVII., from which the large disturbances have been removed, we have for the variations of dip for the year— OhOm = 2h 25m gh 20m Gh 15m Bh Om Oh Sm = 1.2hOm = Bh G5m «15h 50m «17h 45m = 19h 4m =.

Effect of Intermittent Disturbances upon the Yearly Mean of Magnetic Dip—We obtain the following results for the mean magnetic dip from the values of the horizontal and vertical components, pages 365 and 384 :— The Mean Magnetic Dip, as deduced from the whole series of Hourly 120-day series, by 0/-175 Observations, is greater than that deduced from the............... 60-day series, by 0°245 It has been found, p. 3438, that the intermittent disturbances have no effect on the mean declination ; it ap- pears, however, from the above results, that they affect the mean dip, the result deduced from the 60-day series, that least affected by disturbance, shewing a less dip than that deduced from the whole series, by 0-25, which is equivalent to about 08 for the magnetic declination. Effect on the Monthly Mean of Magnetic Dip.—Making use of the quantities for the two components of force, pages 365 and 384, we obtain the following corrections of the means of magnetic dip from the 10-day and 5-day series, to those from the complete series of observations in each month :— Jan.

Effect of Disturbances on the Hourly Means of Magnetic Dip—tThe following are the differences of the hourly means of magnetic dip for the year, or the means as deduced from the whole series, minus the means as deduced from the 120-day and 60-day series of observations (see Table LV. and p. 392), each series having the same mean value.

The effect of disturbances in diminishing the dip is a maximum when the effect upon the magnetic declination is zero. ToTAL MAGNETIC FoRCE.

The observations of the bifilar magnetometer made at St Helena, in the four years, 1842-3-4—5, have been examined inasimilar manner. ‘The temperature coefficient has been deduced from the bifilar observations, and the observations have been corrected by it. The variations of the horizontal component at St Helena may be considered as the variations of the total magnetic force, as much at least as they are the representatives of the varying magnetic inclination at Toronto and Makerstoun. The mean of the results for the four years (three years only for the first ten weeks) indicates that the horizontal component at St Helena is a maxi- mum in the beginning of June, and a minimum in the beginning of December: this result differs from that obtained by Colonel SABINE from two years of the same observations (chiefly, perhaps, because the results for the separate years are not very consistent among themselves.) In Colonel SABINE’s result there appears to be a connection between the intensity and temperature of the air; the magnetic force appearing greatest when the temperature is greatest. Such a result would be in opposition to the well-known con- nection between the magnetic intensity and mean temperature at different parts of the earth’s surface; in that case, the intensity seems greatest where the mean temperature is least. Perhaps, however, the St Helena Observatory is not well situated for the de- termination of such a connection as a general annual law, since, in the first place, the range of temperature is small (the difference between the mean temperatures of the hottest and coldest months being only 8° Fahr., about 4 of the difference at Makerstoun) ; and, in the second place, the Observatory is placed above extremely magnetic rocks; the whole island indeed is one large magnetic mass. But perhaps the result obtained from the four years’ observations is the strongest objection, since it places the maximum and mini- mum of magnetic intensity at the two times of yearly mean temperature. 396 RESULTS OF MAKERSTOUN OBSERVATIONS, 1844. Variations of Total Magnetic Force with reference to the Moon's Age.—lIt is evident, from the first portion of Table LVILI., that the total force is a minimum about opposition and a maximum about conjunction ; this will also appear in the following means of groups :— 14 days to 16 ey Full Moon, 0-:000017 29 days to 1 day, New Moon, 0-000132 i ai le 20 0:000068 Dee 5 days, 0:000126 a) [tae ete 24 ... 0:000135 Gunes pea 0-000133 DiBye dos aes PS) oe 0-000130 sO - Lees. 0-000034 The value of the force does not vary greatly for the 10 days before and the 10 days after conjunction, the mean value being 0:000131; the mean for the remaining 10 days, including opposition, being 0:000034. There is a slight appearance of a secondary minimum at conjunction, the maxima occurring before and after that epoch. The incomplete series of observations for 1843 gave nearly the same result, the secondary minimum at con- junction being better marked. Variations of the Total Magnetic Force with reference to the Moon’s Declination.—The following are means of groups of the second portion of Table LVII. :— 27 days to 1 day, Moon farthest North, 0:000123 | 18 days to 15 as Moon farthest South, 0:000103 2oaee 5 days, 0:000070 EG) vem 19 0:000091 ig Sane oe 0-000060 2 re A mes ; 0:000054 Sab unr ctael © Suet 0:000054 os oe 2G ont 0:000058 The simple means and the means of groups indicate that the total magnetic force is a maximum when the moon has its greatest north and greatest south declination ; it is a minimum between these epochs. This result also was obtained from the incomplete series of observations for 1843. TABLE LVIII.—Diurnal Variations of the Total Magnetic Force in 1844, as deduced from Tables XX VII. and XLITI.

In the months of June and July the principal minimum occurs between 10" and 11? a.m. and the secondary minimum about 2" a.m.; the two minima have nearly equal values in the months of May and August; the minimum about 25 a.m. is best marked in all the remaining months of the year. The principal maximum occurs between 4" p.m and 7" p.m, in each month of the year, and earlier, on the whole, in the equinoctial than in the solstitial months. Leaving the more minute considerations with respect to the variation of the diurnal law with season to be made in connection with another year’s observations, we shall only farther at present consider the diurnal variation for the year as obtained from the observations upon the selected 120 and 60 days free from disturb- ances. The variations for these series deduced from the last columns of Tables XXVIII., XXIX., XLIV., and XLV., and reduced so that the mean for each series equals the mean for the whole series in the last column of Table LVIII., are as follow :— Series. am.

The range of the variations is much diminished in the selected series, the whole range for the 120-day series being 0:000274, and for the 60-day series only 0:000266, little more than half the range for the whole series. The range from the secondary minimum to the secondary maximum in the 60-day series is only 0-000020, so that the selection of days nearly altogether free from disturbance has the effect here also of nearly obliterating the secondary minimum and maximum. Ranges of the Mean Diurnal Variation of the Total Magnetic Force.—The ranges of the diurnal variation for each month, as deduced from the whole series of observations, are as follow :— Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Nov. Dec. 0:000 | 233 298 782 784 679 489 561 688 615 671 602 280 The diurnal range of the total force is a principal minimum in January, and a secondary minimum in June; it is a maximum at the equinoxes. There is no doubt, however, that if the diurnal variations for each month were deduced from the selected series of observations, the ranges would be found to obey the same law as that already obtained for the vertical component from the same series.

Portion of these effects is due to consecutive disturbance, such as secular change, but the elimination of that portion would not affect the generality of this conclusion. By subtracting the previous quantities from the monthly mean variations for the total force, p. 395, we would obtain the monthly means as deduced from the 10-day and 5-day series; the resulting means give the same law as that obtained from the means for the whole series. Effect of Disturbances on the Hourly Means of the Total Magnetic Force-—The following are the differ- ences of the hourly means of the total force, or the means as deduced from the whole series minus the means as deduced from the 120-day and 60-day series of observations; each series having the same mean value.

The positive effect of disturbance upon the mean of the total force, is a maximum at 55 10™ p.m.; the negative effect is a maximum at 2"10™ a.m, The effect is zero at 104 20™ a.m., and at 9° 10™ p.m. The effect of disturbance in diminishing the westerly declination, and in increasing the dip, is a maximum at 9" p.m., when the effect on the total force is zero; the effect of disturbance in increasing the westerly declination is a maximum at 10" a.m.; at the same hour there is a secondary maximum of effect in increasing the dip, and at the same hour the effect on the total force is zero. On the contrary, when the effect of "disturbances upon the mean total force is a positive maximum,—namely, at 5” p.m., the effect upon the mag- netic declination and dip is zero; and when the effect upon the total force is a negative maximum at 2 a.m., the effect upon the magnetic declination and dip is nearly zero; so that, when the effect of disturbance upon the direction of the magnetic force is a maximum, the effect wpon its intensity is zero, and vice versa. It is remarkable, even merely as a coincidence, that the effect of disturbance upon the direction of the magnetic force is a maximum when the sun is on or near the magnetic meridian, and zero when nearly at right angles to that plane; while the effect of disturbances upon the intensity of the magnetic force is zero when the sun is near the plane of the magnetic meridian, and a maximum when in the plane nearly at right angles to it, for the effect of disturbance differs little at 4" a.m. from that at 2" a.m. when it is a maximum. 400 RESULTS OF MAKERSTOUN OBSERVATIONS, 1844.

Several of the aurore noted faint were marked as somewhat uncertain, on account of remaining twilight or clouds; there can be little doubt, however, that-in every case they were real aurore, as they were accompa- nied by more or less marked magnetic disturbances. Tue AvRORA BOREALIS. The previous Table contains a list of all the aurore observed at Makerstoun in the year 1844. The number is too small to expect from it alone any general results; but as it is believed that a discussion of the number seen gives nearly the same results as will be obtained from more extensive series, the conclusions are stated here. The number of aurorz boreales seen at Makerstoun in 1844 was 26. The numbers seen in each month were as follow :— Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Nov. Dec. 0 2 5 2 3 0 0 2 0 3 6 3 The number is zero in June and July; the shortness of the night and brightness of the twilight would of themselves diminish the number observed in these months; for the opposite reason we should expect a greater number about the winter solstice: this, however, is not the case,—the greatest number occurs in the months of March and November. Between the summer olstices of 1843 and 1848, 5 years, 85 aurore were seen at “Makerstoun, which, considering the year in 4 quarters each of which has a solstice or equinox at its centre, occurred as follow :— Vernal equinox, 32; Summer solstice, 6; Autumnal equinox, 23; Winter solstice, 24. Although the quarter at the winter solstice is so much more favourable for seeing aurore, on account of the greater length of the night, the average number at the equinoxes is greatest. This result was long ago obtained by Mairan in his Traité de l’Aurore Boréale, and has lately been | obtained by M. Hansteen from observations of nearly 300 aurore seen in the years 1837-1846 at | Christiania.* It is, of course, partly accidental, that there is an approximation to the law distinctly evident in the single year’s observations for 1844: the fact is stated chiefly in order to point out its connection with a result of the previous discussions. The law of the frequency of aurorz is the same as that of the intensity * Mémoires de l’Académie Royale de Belgique, tome xx. Kamtz, also, in his Complete Course of Meteorology (translation by Walker, p. 458), gives a Table, comprehending 3253 aurore. The following are the numbers by Kamtz and Hansteen :— Jan. Feb.

When the numbers for 1844 are combined with reference to the moon’s age into four quarters, two of which have the epochs of new and full moon in the middle, we obtain the average for each day of the moon’s age as follows :— 2'74— 34 New Moon,... 0°40. 44_.114... 0°75. 124 184 Full Moon,... 0°86. 194 264... 1°38. The same law of variation is obtained from the 91 aurore seen between January 1843 and June 1848; these give the following mean numbers :— 274 34 New Moon,...1:90. 4¢4—114...2-62. 124— 18? Full Moon,... 3°43. 194— 264... 4-00. If we suppose that the number of aurore should be the same at all ages of the moon, then we would expect, that on account of the great number of faint aurore rendered invisible by the moonlight, the greatest number would be seen about new moon. This is not the case; the greatest number has been seen in the quarter intermediate between full moon and new moon; and this conclusion, it is believed, will be obtained from larger series of observations. Since, then, the greatest number of aurore are seen between full and new moon, it is certain that the greatest number occur nearer full moon than the epoch of visible maximum ; and it is pro- bable that the greatest number actually occurs at full moon, though the moonlight will always render a direct determination of the fact impossible.* It appears also from Table LXI., that the greatest numbers of aurore occur before midnight. As actual measures of the intensity cannot be easily taken, it can only be stated as a gene- rally observed fact, that the maximum brilliancy of aurore occurs between 81 and 11 p.m. Both the probable re- sult for the moon’s age and the other result for the diurnal law, agree with the laws deduced for the magnetic disturbance in the preceding pages; the magnetic disturbance is a maximum at full moon, and the disturbance of the direction of the magnetic force is a maximum about 9"10™ p.m., the time of maximum frequency and intensity of the aurora; there can be little hesitation, therefore, in saying, that the laws of the aurora borealis may be concluded from those for the magnetic disturbance, and vice versa. In every case of observed dis- turbance, including disturbances of the most minute character, in the year 1844, when the sky was sufficiently free from clouds and moonlight, and twilight absent, the aurora was seen; this remark, I believe, will apply to the observations in other years. It is difficult, mdeed, to understand the cause of the doubt which remained so long with respect to the fact of this simultaneity; some farther evidences of its generality may be noticed at another time. * It is worth referring to the past year, as giving an illustration of the law of aurora and disturbance, as related to the moon’s age. The following is a list of all the aurore seen at Makerstoun, in the year between the solstices of 1847 and 1848 :— 1847. Aug. 22. Faint Aurora.,............... 3 days before Full Moon. Sept. 27.

Brilliant Aurora, ......... 0 The aurore marked brilliant were the most beautiful and vivid, despite the moonlight, ever observed at Makerstoun, and they were accompanied by magnetic disturbances of the same character,—the largest, it is believed, ever observed. Neglecting the faint aurore, it will be seen that in 8 lunations brilliant aurore were observed within three days of full moon, only one brilliant aurora having been seen at Makerstoun farther from full moon,—namely, that of September 29. It is conceived that these observations of themselves give a great probability to the conclusion, that the maximum for the aurora and magnetic dis- turbance is at full moon. It is not, of course, supposed that brilliant aurore occur only near full moon, but that they occur more frequently at that than at any other epoch; it should be remembered that what may be considered a vivid aurora in the absence of moonlight, would become faint in its presence, and vice versa.

The observations of the dry and wet bulb thermometers were usually made about 1™ before the hour of Gottingen mean time, that is about 9™ after the Makerstoun hour; the observations of the barometer were made _ about 1™ or 2™ after the hour of Gottimgen mean time, that is about 11™ or 12™ after the hour at Maker- stoun. The hour, astronomical reckoning, without the additional minutes, of Makerstoun mean time is given in the Tables : in the remarks, the observation has been supposed to be made 10™ after the Makerstoun hour, and civil reckoning is used.

The variation of temperature for 1844 has the mean form; the three months having the highest mean tempera- ture are June, July, and August, and the three having the lowest mean temperature are December, January, and February ; the means for the meteorological quarters are— Winter, Dec., Jan., Feb.,... 33°°99 Summer, June, July, Aug., 54°59 Spring, March, April, May, 44°°52 Autumn, Sept., Oct., Nov., 45°04 The mean temperature for the year 1844 = 45°-04 Differences of the Daily Mean Temperatures from the Monthly Means.—The following are the average dif- ferences for each month of 1844 :— Jan.

The o8cillations of the daily mean temperature do not appear to be at all related to the variations of the diur- nal range. Approximations to the Daily Mean Temperature.—The following are the mean errors, for each month of 1844, of the mean temperature for a civil day, as obtained from the observations of the self-registermg thermo- meters by the formule mM, + My M m, + M 2 ale 5) J: @ eel 5) +¢ where ¢ is the approximate mean temperature for the civil day for which m, is the minimum temperature of the morning, m2 is the minimum temperature on the morning following ; M is the maximum temperature, and c is the correction of the monthly mean, obtained by the previous portions of the formule, to the true mean, (see Table IV.)

The values of the corrections ¢ may be determined from two or three years’ observation. It is pro- bable that better approximations to the mean temperature of the astronomical day would be obtained by means _ of the formula M, + M, = = a ime where M, and Mz are the maxima near the commencement and near the termination of the day, m being the intermediate minimum.

SK OOCOONOONPWNE OO — — It should be remarked, that the changes of temperature between 115 10™ p.m., and 125 10™ a.m., are slightly inaccurate in Table II.; this is due to the variations of temperature between 11 10™ p.m. of the Saturdays, and 12" 10™ a.m. of the Mondays, and to the difference between the temperature at 125 10™ a.m., the first hour of the month,—and 11" 10™ p.m., the last hour. The changes of temperature between 115 10m p.m., and 12" 10™ a.m., as determined by the observations for each month, where the interval was only one hour, are as follow, namely, temperature at 12 10™ a.m., minus temperature at 11° 10™ p.m. :— Jan.

By means of this measure, we find the values of the approximations to be in the following order, commencing with the highest :— ist. 5510™a.m.,and 4510™p.m. 2d. 95240™4.m., and 10"10™p.m. 3d. 9540™am.,and 9540p, 4th. 10°10™a.m.,and 11"10™p.m. 5th.10"10™a4.m., and 10210™p.m. 6th. 5° 10™.m., and 11" 10™4.m, 7th. 9210™4.m.,and 9210™p.m. 8th, 7210™ p.m. 9th.

Ifthe approximations to the mean for the year should be nearly constant from year to year, then the best approximations to the monthly means should be determined by em- ploying the mean error after correcting by the yearly difference. Thus, if the monthly means for 9" 40™ a.m and 10810™p.m., are corrected by +0°23—the correction for the yearly mean from the observations at the same hours—the average error of the monthly means is only 0°13.

Assuming that the change in the means from 11 to 12" is the same as from 104 to 11", the differences between the means for 12" so obtained, and the means for 12 at the com- mencement of each series, will be due to the causes noticed above, and they may be considered as differences which have gradually increased from the first to the following 12". By correcting the observations for such gradual changes, the epochs of maxima and minima will be determined with more accuracy. Table XXII. has been formed in this way.

Annual Variation of the Pressure of Dry Air—If we assume that the means at the foot of Table X. accurately represent the pressures of the vapour of water in the atmosphere, the mean pressures of the dry air will be obtained by subtracting them from the means for the total atmospheric pressure, Table XVIII. The resulting mean pressures of dry air are as follow :— in. Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Nov. Dec. 29 | 477. 141 +320 547 “(07 ~ 27s) ‘258 “184 466 “121 "sven + The least mean pressures of dry air are those for October, August, and February, and the greatest are those for May and December. The means vary in the same manner as those for the total atmospheric pressure. Diurnal Variation of the Pressure of Dry Air.—The following Table contains the diurnal variations of the pressure of dry air, obtained from a comparison of Tables XIII. and XXII. The variation of the pressure of the dry air thus determined is double in winter, like that of the total pressure; there is a secondary maximum and minimum in autumn, and the variation is single, with some irre- gularities, in the other quarters, and for the year. The epochs of maxima and minima are as follow :— Max. Min. Max. Min. Winter. Nov., Dec., Jan.,...... + Qh 40™ p.m. 6® 50™ a.m. 10° 0™ a.m. — 15 40™ p.m. Spring.

The law of variation is so different in the different quarters of the year, that no confidence should be — placed in these results, as exhibiting the diurnal variation of the pressure of dry air: it appears extremely © probable that the true pressure of aqueous vapour in the atmosphere is not to be determined by means of the psychrometer.

Table XXV. contains the means of the maximum pressures of wind recorded by the anemometer between the hours of observation: Table XXVL., which follows, contains the means of the maximum pressures recorded within about 10™ at the hour of observation. The latter, therefore, will represent more nearly the mean pres- sure of the wind; they would require, however, to be multiplied by a constant coefficient to obtain the true mean ; this coefficient has not been yet ascertained. Annual Variation of the maximum Pressures of Wind.—From Table XXV. the mean of the maximum pressures between the hours of observation was greatest in November and least in July. The following are the means for the meteorological quarters :— lb. lb.

From both Tables the diurnal variation for each month shews some irregularities ; neglecting the means for December, the maximum force of wind (from Table XXXI.) occurs between noon and 2h p.m. and the minimum occurs between 9" p.m. and 6" a.m.; in December the maxi- mum pressure occurred about 10" p.m. and the minimum about 104 a.m. The approximate epochs of pressure of wind from Tables XXX. and XXXII. for each of the astronomical quarters and the year are as follow :— From Table XXX.

The differences between the two sets are chiefly in the times of minimum pressure, and these times are not well marked. In the winter quarter, con- sidering the means from Table XXXII, the pressure varies little from 9" p.m. till 8" a.m.: there is the appear- ance of a secondary maximum about midnight. In spring the minimum occurs at midnight, but there is again a minimum about 55 a.m., a secondary maximum occurring between these times ; im summer the pressure is nearly constant from 9" p.m. till 4" a.m., and in autumn it is nearly constant from midnight till 6" a.m. In the mean for the year the pressure of wind varies little from 9" p.m. till 6" a.m.; there is a slight indication of a secondary maximum about 2" or 3" a.m.: the maximum pressure occurs almost exactly at the time of the maximum temperature of the air. Annual Variation of the number of times which the Wind blew in 1844.—From Table XXXIII. the num- bers of times which the wind blew with a force of 0-1 Ib., or upwards, at the hours of observation in 1844 were for each month as follow :— Jan.

On the whole the wind blew seldomest about the winter solstice and oftener about the equinoxes than about the summer solstice: this result is the reverse of that for 1843. In 7536 observations, the wind blew 0:1 Ib. or upwards 4245 times, or 13:5 times a-day of 24 observa- } tions, or 563 times in 1000.

Annual Variation of the Mean Pressure of Wind when blowing.—The annual variation of the mean pressure of wind, obtained by dividing the sums of pressures observed, by the whole number of observations, has been already considered. If, however, we divide the sums of pressures observed by the number of observations for which a pressure of 0-1 Ib. or more was observed, we obtain the means of pressures for the time which the wind blew. The sums of pressure for each month from Table XX XIII. are as follow :— Jan. Feb. March. April. May. June. July. Aug, Sept. Oct. Nov. Dee. Ib. Ib. Ib. lb. Ib. Tb. Ib. lb. lb. Ib. Ib.

Annual Variation of the Resultant Pressure of the Wind.—The resultant mean, with reference to the whole number of observations, was greatest in April and least in July, September, and December. It was greatest in the meteorological summer and least in the meteorological winter ; it was greatest in the astronomical spring and least in the astronomical summer and winter. The resultant mean, with reference to the time during which the wind was blowing, was greatest in January and was least in September ; it was greatest in the meteorological summer and least in the autumn ; it was greatest in the astronomical spring and least in the summer. The direction of the resultant was between W. and N. in February, March, and July; between S. and W. in January, April, June, August, September, and October; between N. and E. in May; and between §S. and E. in November and December. The direction of the resultant for the meteorological quarters is between S. and W. in the quarters, spring, summer, and autumn, and it is nearly W. in winter ; it is between S. and W. in all the astronomical quarters.

Times which the Wind blew Grom the different Points of the Compass.—It will be observed from the sums of times, Table XXXV., that the sums are greater for each of the 16 principal points than for the points imme- diately preceding and succeeding ; ; this is due to the preference given by the observer in all doubtful cases to the principal points. The wind blew oftenest in 1844 (as in 18438) from the SW. and seldomest from the SE. by E. If we take the sums of the times for the 5 points SSW. to WSW. corresponding to SW., from WSW. to WNW. corresponding to W., and so for the others of the 8 principal points, we obtain the following numbers :— SW. W. NW. N. NE. E. SE. 8. 1642 781 496 494 877 323 230 572 These sums give the same result as the more limited series for 1843. The wind blew oftenest from SW. : the number of times diminishes to NNW., where it is a secondary minimum ; it increases to NE., where it is a secondary maximum, and diminishes again to about SE. by E., from which the wind blew seldomest. The wind blew twice as often from SW. as from NE., and twice as often from NW. as from SE. The numbers for the points SE., NW., NE., and SW., are approximately in the ratio of 1, 2,4,and 8. The ratio of the numbers for the same points in 1843 was as 1, 4, 8,and16. The wind blew twice as often from the points included between N., W., and §., as from the points in the opposite semicircle ; the number from the hourly observations being for the former 2823, and for the latter 1422: the same result was obtained from the observations for 1843. Sums of Pressures with which the Wind blew from the different Points of the Compass.—The greatest sum of pressures is that for SW., and the least is that for SE. by E. The sums of pressures for each of the 5 points, including the 8 principal points as above, are as follow :— Sw. Ww. NW. N. NE. BR. SE. S. lb. lb. 1b. lb. ee ib: lb. Ib. Ib. 1104°7 643-4 358°6 277-7 452°3 219°8 160°6 30274 The sums of pressures are a maximum about SW.; they diminish from thence to W., NW., and N., a secondary minimum occurring about that point ; the sums increase thence to NE., where they are a secondary maximum, and diminish from NE, to SE., where the sums of pressures are least ; they increase from the mini- mum at SE. to the maximum at SW. Mean Pressure of the Wind, while blowing, for different Points of the Compass.—Dividing the sums of pressures, given by the above, for the 8 principal points by the number of times which the wind blew, we obtain the following as the mean pressures with which the wind blew from the different points :— SW. Ww. Nw. N. NE. E. SE. S. Ib. lb. Ib. Ib. lb. lb. Ib. Tb. 0°67 0°82 0°72 0:56 0°52 0°68 0:70 0°53 The wind, therefore, on the average, blew with the greatest force from about W. by N., and with the least force from about NE. This result is not nearly so distinct and regular as that for 1843, in which year the: wind blew with the greatest force from NW., and with the least from NE. Diurnal Variation of the Resultant Pressures of the Wind.—The resultant mean for the time during which the wind blew is a secondary minimum about 5" 40™ a.m., a principal maximum about 1» p.m., a principal mini mum about 6" 40™ p.m., and a secondary maximum about midnight. (See Table XXXVI.) The resultant means for the whole number of observations indicate generally the same law. Diurnal Variation of the Direction of the Resultant Wind.—The result exhibited in the last column Table XXXVI. was obtained from the observations for 1843, though not so distinctly. The direction of th wind is nearly W. at 2" p.m., and it is nearly SW. after midnight. The direction of the wind is nearest W. about the time of maximum temperature, and nearest S. about the time of minimum temperature. The direction of the wind, therefore, is most westerly when its velocity is greatest, and most southerly when the velocity i: least. It is extremely probable that both facts may be explained by the greater descent of the upper current when the air at the surface is most rarified, 2. ¢., at the time of maximum temperature.

Table XXXVII. has been formed from the observations of the motions of the clouds and surface wind given in the Tables, pages 172-308, in the following manner :—When several observations of the direction of the wind have been obtained, at successive hours, with simultaneous observations of the direction of motion of the current of scud, the mean direction of the wind has been taken, and the mean direction of the cloud motion, the direction of the lower current (counted in points from N. by E., §., and W.) has been subtracted from the direction of the upper current, and the difference entered with its proper sign as one result; when the lower current is from an easterly point the difference is positive if the upper current be most southerly ; when the lower current is from a westerly point the difference is positive when the upper current is most northerly. When in the same day the direction of either current has changed considerably, two or more results have been obtained ; in several cases, especially for the higher currents, a single good comparison has received the value of a result: on the average, each result (the whole number of which is given in the first column for each quadrant, Table XX XVII.) for the differences scud minus wind has been obtained from five pairs of simul- taneous observations, for the differences cirro-stratus minus wind and cirro-stratus minus scud from three pairs, and for the differences cirrus minus wind and cirrus minus scud from two pairs of simultaneous observations. All observations for the direction of the surface wind were rejected for which the force was less than 0:1 Ib., or for which the pressures of 0-1 lb. were, from variable gusts, due to local causes. All the results for the lower current in the quadrant N. to E., which were positive, were combined, and the mean difference obtained, simi- larly for the negative differences ; and so for the other quadrants. Thus, for the difference of motions scud minus wind in the quadrant N. to E., 57 results were obtained which gave positive differences, the mean dif- ference being + 24°; 34 were obtained which gave negative differences, the mean being — 34°, and there were 3 results without any difference of motion. The mean of the whole 94 results shews that the coud moved from a point 2° south of that from which the surface current proceeded. Differences of the Directions of Motion of the Upper and Lower Currents of Air.—In the three quadrants E. to §., 8. to W., and W. to N., the mean direction of the superior current is always positive of the mean direction of the inferior current, and this is true in all the five series of comparisons. In the quadrant S. to W., in which the greatest number of observations were obtained, the law is very distinct. The scud current proceeds on the average (of about 800 comparisons of the motions of the two currents) from a point 21° north of that from which the surface wind proceeds ; the cirro-stratous current (on an average of about 300 comparisons) proceeds from a point 30° north of the surface wind ; and the cirrous current proceeds (on an average of about 200 com- parisons) from a point 40° north of the direction of the surface wind, From these results we might conclude that the cirro-stratous current is 30° — 21° = 9° positive of the scud current, and that the cirrous current is 40° — 21° = 19° positive of the seud current ; the quantities actually obtained from comparisons which are more or less — independent are + 17° and + 20° respectively, the former differing somewhat in value, though accurate as re- gards sign. Such consistency is only to be expected where the differences of motion have been determined from a sufficient number of comparisons. The results, however, for the quadrant E, to 8S. are nearly as consistent, though obtained from few observations. In this quadrant the scud is 16° positive of the surface current, and the cirro-stratous is 25° positive of the surface current, whence the cirro-stratous should be 25°—16°=9° positive of the seud current; the result from comparisons which are partially or wholly independent is + 11°. The comparisons in the quadrant W,. to N. indicate on the average in all cases that the upper current is positive of the lower, but the differences do not increase regularly with the height of the current. The quadrant N. to E. contains the only exception to the law of the other quadrants ; in this quadrant the cirrous current is not positive of the inferior currents; the comparisons, however, are very few. The scud and cirro-stratous currents are both positive of the surface current, the former not much, probably because the scud current from the NE. is generally very low. Taking the averages for all the quadrants, we have Seud current minus surface current, from 347 results, ee 1700 comparisons) = + 13°.9 Cirro-stratous current minus surface current, ... 223 ......

By the greenhouse-gauge, the greatest amounts of rain fell when the moon was both new and full, and the least fell at the quadratures. It is right to state, that much confi- dence could not be placed in any result from this gauge, since it is sheltered from NE. winds by neighbouring trees, and its position upon the ridge of the greenhouse-roof seems to unfit it for even relatively accurate determinations ; as the summations were made for this gauge, it has not been considered proper to withhold them. By the observatory-gauge, the greatest amount of rain fell about three days after new moon, and the least fell at full moon; the same result is obtained from the sums for both gauges. The result for the obser- vatory-gauge is very distinctly marked. PRINTED BY NEILL AND COMPANY, EDINBURGH. y Magneti cal Observations.
