The Magnetical and Meteorological Observatory at Makerstoun, in Rox- burghshire, was erected by General Sir THomas MAKDOUGALL BRISBANE, Bart., in the year 1841. The geographical co-ordinates are as follow :— Latitude, ; 5 5 é 5 55° 34 45” N.* Longitude, pi : : ; : 04 10™ 3-5s W. of Greenwich.t} Height of the barometer cistern above mean water at Berwick, 213 feet.| 2. 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.

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 THomaAs 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 THomas, 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 JouN 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 } inch thick ; it fits into a stirrup 6, 3 n A A sa ‘ 1 1 t ‘ ‘ 1 1 1 1 1 1 1 1 ' 1 1 1 1 , whose two eyes receive an axle to which the suspension thread is attached ; near the north extremity it carries a scale divided on glass, ¢; near the other, at a dis- tance from the scale of about 12 inches, the focal length, it carries a lens of 13 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 Xil 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 k, 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 7, 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 1843, 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.

The determinations of the corrections are given in the volume for 1843. 10. Correction for the torsion force of the suspension thread. The errors due to the torsion force of the suspension thread are produced, first, by the magnet moving out of the plane of detorsion ; secondly, by the variation of this plane (due generally to the varying humidity of the atmosphere). The error due to the former, even in the most marked cases, is less than the probable error of * For details, see Introduction to the Observations for 1843, pp. xv. and xvi. { Ibid., pp. xvii. and xxi.

If the plane of detorsion be that of the magnetic meridian, and the magnet be deflected through an are w by turning the arms of the torsion circle w, the torsion is w—u, and the equation of equilibrium is m Xu =(w—u) where m is the magnetic moment of the bar, X is the horizontal component of the earth’s magnetic force, and H is the torsion force for an are equal to radius, whence, ifm X = F, * u erties naa w—U is the quantity by which the deviations of the magnet from the plane of detorsion should be multiplied to obtain the decrements due to torsion. If n be the observed deviation, ® n = the true deviation. The following are observations for the value of © for the suspension thread placed in the instrument, June 22, 1843, and for the long scale magnet :— Aug. 74 2h, 1843.

These values have not been used for this correction; the last determination has been employed in the observations of absolute horizontal intensity made in 1844. 11. The second and most important error due to the torsion force is that pro- duced by the variation of the plane of detorsion. Unless when the period and extent of change is known, this can only be corrected by removing it; this is done occa- sionally in the following manner :—The magnet, with its stirrup, bemmg removed, a brass bar and stirrup of nearly the same weight and dimensions is suspended ; the rectangular box being removed, the cylindrical box being completely closed, and the shutters removed from the glazed lid, the extremities of the are of vibration are observed through the latter; the marble slab beneath having radii drawn for every 5° on each side of the magnetic meridian, the positions of rest at the extremities of the ares are estimated to $°; the deviation of the mean position from the magnetic meridian is known, and the arms of the torsion circle are turned through an equal angle in the opposite direction ; the position of rest is then in the magnetic meri- dian. Much time and care were bestowed upon these observations, as the error due to this cause is by far the most serious that occurs in connection with the de- clinometer. DECLINOMETER. XV 12. The following are all the observations for the elimination of torsion made in 1844, together with all the occasions on which the magnet was touched or removed from its box. When the mean position of rest for the north end of the brass bar was found to the east of the magnetic north, the torsion existing is considered posi- tive, and the effect of + 10° of torsion= —0':84 (from the previous observation for the value of =) In the first case below, the north end of the brass bar was found to rest 2° east of the magnetic north; and the brass bar was thereafter made to coin- cide with the magnetic meridian.

The observations of the declinometer were made in the following manner :— The points of the scale which coincided with the vertical wire of the reading tele- scope were noted 18 seconds before the minute of observation, at the minute, and 18 seconds after the minute: the scale readings at these periods being a, b, and c, the mean position is deduced by the formula a This method was employed till Oct. 15, 1844, when the copper ring for checking the vibrations having been re- moved, the three scale readings afterwards were always made at the extremities of the ares of vibration; the first reading being made at that extremity of the vibra- tion which occurred between 27 seconds and 9 seconds before the minute of obser- vation. Even after the copper ring was removed, the arc of vibration was small, seldom above 3’, and generally less than 2’; during disturbances, however, the are is often considerable, and frequently in these cases only two observations are made, the mean position being obtained at once from the mean of the two readings at the extremities of the vibration which oceur between 18* and 0° before, and between 0° and 18* after, the minute of observation. 15. All the observations of declination in this volume are absolute. They are rendered so as follows :— The middle wire of the theodolite telescope is brought to coincide with the ver- tical wire of the fixed reading telescope (7.); the three verniers of the horizontal cirele are then read; the theodolite telescope is turned (on the vertical axis of the circle) until its middle wire coincides with the vertical line on the north meridian * See Introduction, 1848, p. xxi, DECLINOMETER. XVil mark of Sir THoMAS BRISBANE’S (the western) transit in the Astronomical Obser- vatory, and the verniers are again read. In order to obtain the reading of the horizontal circle for the astronomical meridian, the theodolite telescope was placed as nearly as possible in the meridian, and being accurately levelled, the time of the sun’s transit was observed by the Magnetic Observatory clock. The sun’s meridian passage was also observed by Sir THomAs BrisBANE with his western transit in the Astronomical Observatory, and the clocks in the two observatories being imme- diately compared, the true time of transit by the clock in the Magnetic Observatory was obtained. The difference, if any, between the true and observed times, was due to error of azimuth ; the latter, being very small, was obtained from the former in multiplying by the factor, cosine sun’s declination cosine sun’s altitude 16. If A’ be the difference of the horizontal circle readings for the wire of the fixed telescope and for the north mark, Z be the azimuth of the north mark, and D be the angle at any instant contained by the line of collimation of the reading telescope and the adopted zero scale reading, the true westerly declination at that time will be 180° — A'+ Z=D. The values of 180°—A’=A, obtained in 1844, 1845, and 1846, are given in the following Table :— MAG. AND MET. oss. 1844. e xvill INTRODUCTION TO THE MAKERSTOUN OBSERVATIONS, 1844.

XIX UNIFILAR MAGNETOMETER AND OBSERVATIONS OF THE ABSOLUTE HORIZONTAL INTENSITY OF THE EARTH’s MAGNETISM. 18. In the beginning of April 1843 two small wooden houses were erected about 19 yards to the north of the Magnetic Observatory ; the larger of the houses contains the unifilar magnetometer and the dip cirele, and the smaller, which is 10 feet to SSE. of the larger, contains a reading telescope for the magnetometer. The unifilar magnetometer rests on a strongly-braced wooden stand, which is fixed by copper battens and plaster of paris to a stone slab, resting on a stone founda- tion separated from the floor ; the top block of the stand, a solid piece of mahogany, carries a vertical box enclosing the suspension thread and supporting the torsion circle, this box is open on two opposite sides near the stand top; a horizontal box slides on the vertical one, and when close to the stand top the magnet is completely enclosed ; an internal box was afterwards added, and all the precautions already indicated (6.) for the declinometer were taken. The magnet used when observations of absolute horizontal intensity were made was that usually in the declinometer, a spare magnet being fitted with a short scale (8.) was substituted for it ; the telescope (that intended for a collimator to the bifilar) was placed in the smaller wooden house, on a stand in all respects similar to that for the unifilar: the two houses were con- nected, during observations, in the line of collimation of the telescope and magnet by a wooden tube blackened within. A beam of straight well-seasoned fir, 11 feet long, 32 inches broad, and 1? inches thick, was placed on each side (outside) of the larger wooden house, in the line passing through the centre of the suspended magnet, and at right angles to the magnetic meridian ; each beam was let into the tops of two strongly-braced wooden trestles, 7 feet apart, which rested on wooden posts driven into the ground, and which were fixed to the latter by catch-pins, allowing a slight adjustment for the distance of the beams from the magnet; the trestles and beams being removed after each observation. The beams were carefully divided with the aid of a brass standard yard made by Messrs TroucuTon and Simms; the gradua- tions were adjusted to their distance from the suspended magnet in the following manner :—a well-seasoned fir rod, shod with brass at one extremity, and terminated at the other by a capstan-headed screw, by which the rod was accurately adjusted to a length of six feet, was passed through holes in the sides of the wooden house and unifilar box ; the middle of the rod coinciding with the suspension thread, the catch pins of the trestles were then loosened or forced in till the extremities of the six-feet rod coincided accurately with the division 3 feet on each beam. The deflecting magnet was adjusted to the graduations on the beams with the aid of a lens; in 1844 the graduations were marked on brass pin-heads placed in the beams. The fixidity of the trestles was verified in general after each observation, and the accuracy of the graduations on the beams was verified usually before each observation. XX INTRODUCTION TO THE MAKERSTOUN OBSERVATIONS, 1844. 19. The value of the absolute horizontal intensity is determined from the ob- servations as follows :—If 7 be the distance from the centre of the suspended magnet, at which the centre of the deflecting bar is placed on the wooden beam, its axis being in the line at right angles to the magnetic meridian passing through the centre of the suspended magnet; and if w be the resulting angle, through which the suspended magnet is deflected, then since, by GAuss’s theory, the ratio of the magnetic moment m of the deflecting bar to X, the horizontal component of the earth’s magnetic force, is given by the following formula m_ 1s ton u ieee eS xX 2 14+ 442+ ke. ae i where p and q are quantities depending on the mode of distribution of the magnet- ism in the magnetic bars, the value of the ratio may be determined from observa- tions at three distances; it is probable, however, that the deflections are too small in the observations for 1844 to render the consideration of the quantity g of import- ance: the values of the ratio have in consequence been determined from observa- tions at two distances ; if these be x and 7”, and the corresponding deflections be uv and w’, then m_?* tan w—?r tan u X 2 (7?) tan u being obtained from the formula 1+k (6,—6,) a —— ee ———— a tan w=tan [¢ (a, + e— Uy + yet) — f (d,+,d—d;+,d)} Ger 2) |. ip Ga where a is the angular value of one division of the long scale, f is the coefficient for reducing the divisions of the short scale to the value of divisions of the long scale ; u, and ,w are the observed mean scale readings of the unifilar magnetometer, the de- flecting bar, with its north pole towards the east, being at a given distance to the east and west respectively of the suspended magnet; similarly, w and ,w are the mean scale readings when the deflecting bar, at the same distance, has its north pole towards the west: d,, ,d, &c., are the simultaneous mean scale readings of the de- clinometer corresponding to m, w, &c.: 1+ is the torsion factor.

The following are the values of the constants used in the previous formula :— a = 4035 (No. 8.) Ff = 1:115 (No. 8.) = 0:000288.* Aug. 10—Nov. 9, 1843, & = 0:00013. Nov. 9, 1848—Dec. 31, 1845, & = 0-00014. For the thread in the unifilar box and long scale magnet, ® = 0:0012. 21. The comparative observations for u and d were rendered simultaneous thus : The times of vibration of the unifilar and declination magnets being nearly the same, the time at which the unifilar magnet attained one extremity of its arc of vibration was instantly indicated by me to Mr WELSH, who could observe my motions through one of the north windows of the Observatory. He immediately commenced counting the beats of the mean time clock, and at the end of the 18th second (the time of one vibration) both observers commenced making readings of the magnetometers ; those by Mr Wetsu being made at the end of the 18th, 36th, 54th, &c., seconds, and those by myself at the extremities of the ares of vibration. From 7 to 12 con- secutive readings were made thus at every position of the deflecting bar, and from these the mean readings are deduced. In order to render the ares of vibration of the unifilar as small as possible, the deflecting bar was at first moved gradually up to its nearest distance (5 feet); in placing it at the next distance, it was moved rapidly nearly half way, and 18 seconds counted, when it was immediately shifted the other half. When the farthest distance was attained, it was placed vertically, and after 18 seconds, laid down in the reverse position ; it was then moved as before, by half-shifts, to its next position, and so up to the nearest. After comparative readings for that position, the magnet was again placed vertically, and carried to the beam on the opposite side of the suspended magnet ; at the end of 36 seconds it was laid down at the same distance, and with the north pole in the same direc- tion as before. In general, the vibrations were small, seldom above 10’; when larger, the magnet was checked by slightly approaching or removing the deflecting bar at proper times, with reference to the directions in which the suspended magnet was moving. Mr WELSH observed the bifilar magnetometer before and after each comparison, and after each comparison I observed the temperature of the deflecting bar by means of a thermometer lying beside it. 22. The value of the product m X is obtained from the formula where 7 is the ratio of the circumference to the diameter, T is the true time of one vibration of the deflecting bar deduced from the observed time T’ by the formula "(emia | ee tam (1-35 )a+9)" (1 - seam where a and q@’ are the semiares of vibration in parts of radius at commencement * See Introduction, 1843, p. xliii.

The last factor contains the reduction of the time of vibration to the value of the horizontal component for which T, was the time of vibration without the ring ; &, therefore, is the bifilar coefficient, given previously, b, and 6, are the mean bifilar readings when the times of vibration T, and T, were observed, ¢ is the temperature coefficient for the deflecting bar, given above, ¢, and ¢, are the mean temperatures of the bar corresponding to the observations T, and 'T;. As the observations for de- flection are corrected for temperature to the temperature at the time of vibration, the value of m at the time of vibration is taken as the standard value for the series, as far as temperature is concerned, but it requires a correction for the inductive action of the earth, due to the position of the magnet during vibration in the plane of maximum magnetic force ; during deflections the magnet is placed at right angles to the magnetic meridian, and is therefore unaffected by induction : the first equa- tion, No. 22, therefore becomes m x — eu lh *; - T?

XXlil north and south respectively, its centre being in the prolongation of the bifilar magnet, b is the bifilar reading with the deflecting bar away. The deflecting bar was vibrated in the declinometer box after the observations of deflection; it was suspended in a stirrup of silk fibres of the same thickness as the suspension thread, and a small thread of paper being gummed to the extremity next the reading telescope, the times of transits of the paper at the wire of the read- ing telescope towards right and left were observed for every 5 vibrations each way up to the 96th vibration. (See Tables, pages 168 and 169.) A moveable object- glass fits upon the object-glass of the reading telescope, in order to bring the paper slip into view without altering the adjustment of the telescope. 23. The following are the values of the constants used in the preceding formule. ® for the declinometer thread, with the deflecting bar suspended, is obtained from the value when the long scale magnet is suspended by multiplying the latter by the ratio of the moments of the two magnets; thus, moment of long scale magnet is to moment of deflecting bar, as 1-000 is to 0-942, whence, from the values of o for the long scale magnet (No. 10), we have for the deflecting bar and declinometer thread, Aug. 11—Dee. 18, 1843, » = 0:001556. During 1844, » = 0:001482. The rate of the Observatory clock was generally less then 2 seconds a-day. No correction for rate was therefore employed in the determination of T. 24. The following are the details for the determination of K. The deflecting bar is 1-25 feet (= a) in length; 0:0719 feet (= 6) in breadth ; 6216°7 grains in weight (= W). The value of K had been previously determined a? + 6 12 termine it by the more accurate formula given previously ; as it was doubtful whether the declinometer thread could sustain the deflecting bar and an additional weight, a stronger thread was substituted, for which » was determined.

Deflecting bar with scale and lens suspended in brass stirrup ® = 0:003966. As all the observations for the time of vibration of the deflecting bar had been made previously with the bar suspended in a stirrup of silk fibres, in order to employ the second formula for K, given above, depending on the dimensions and weight of the bar, it was necessary in the present case, to determine the value of K for the same mode of suspension. The two values of ® given above for the bar suspended in a brass and in a silk fibre stirrup, without the ring, give © with brass stirrup suspension, to ® with silk stirrup suspension, as, 193: 200, whence, from the value of ® above for brass stirrup suspension and magnet with the rmg, = 0:005966, we find @ for silk stirrup suspension and magnet with ring = 0:004109. Since 4, — 6, = — 15-4 se. div., k = 0:000135, 4, —4 = + 0°-4, g = 0:000288. The true time of one vibration with the ring (reduced to the value of X for T,) T, = 2758403. 25. From the above, therefore, we find for the deflecting bar without ap- pendages, Log K, = 2:9091359 at the temperature of 38°-4 Fahr. The value of K used in the reductions in the present volume has been obtained from K, by the formula K =K,{l+e (4 — 38)? where ¢ is the dilatation of steel for 1° Fahr. = 0:0000068, and #, is the temperature of the bar during vibration. a + b ent 26.

A strong wooden beam having been fixed horizontally in the prolongation of the magnetic axis of the bifilar magnet which lies at right angles to the magnetic meridian, the deflecting bar was mounted in a wooden block having a groove cut to contain the bar; when the deflecting bar was in its place, it was in the same horizontal plane with, its axis was at right angles to, and its centre was in the prolongation of, the axis of the bifilar magnet. The block was fixed to the UNIFILAR MAGNETOMETER. XXV wooden beam: the deflecting bar when removed and replaced, was carried with a thick cloth glove or silk handkerchief, to prevent variation of temperature in handling. In reversing the magnet, the same side was always kept next the bifilar magnet.* TABLE 2.—Determination of the Induction Coefficient for the large Deflecting Bar.

The adopted value of = = 0-0112. This value is very large, more than twice as great as that obtained for small 4-inch bars, and is evidently not to be neglected in the rudest mode of observation for the horizontal intensity. 28. In consequence of the more accurate determination of the value of K, the mo- ment of inertia of the deflecting bar, and of & the bifilar coefficient, and on account of * Tt will in general be preferable to place the deflecting bar to the east or west (as in the present observations), rather than to the north or south of the bifilar magnet, since I have found that the centre of figure may differ considerably from the centre of magnetism; perhaps, for the same reason, when observations are made only on one side of the bifilar magnet, the deflecting bar should be in- verted when it is reversed, since the magnetic axis may be nearer one side of the bar than the other.

The value of X from each pair of deflections is re- duced to the mean bifilar reading for the year.

BIFILAR OR HorRIzONTAL FoRcE MAGNETOMETER. 30. This instrument was made by Grugs of Dublin, and is similar in its general construction to the declinometer, having two boxes, gilt internally and externally as in the latter instrument. The magnet a a, whose dimensions are 15 inches, % inch, and } inch, is placed in a stirrup 6, which carries below it a tube ¢, having a lens d at the extremity next the reading telescope, and a glass scale at the other : the scale has 280 divisions, and the graduation at the 300th division ; increasing readings of the scale indicate increasing magnetic force ; the axle of a grooved wheel e fits into the suspension eyes of the stirrup 6; the magnet, with these appendages, is borne by a silver wire f, passing round the grooved wheel, and having its two extremities pegged into a suspension roller g: the roller is supported by the torsion circle h, which algo bears, beneath the roller, a micrometer-headed screw 2, right-handed where it meets one extremity of the wire, left-handed where it meets the other. The screw serves to render the distance of the extremities of the wire equal to the diameter of the grooved wheel ; the screw and suspension roller turn with the verniersk. A copper ring encircles the magnet, in order to check the vibrations. A thermometer by Apts and Son is enclosed by a glass tube passing through both boxes, the stem XXVIII INTRODUCTION TO THE MAKERSTOUN OBSERVATIONS, 1844. of the thermometer, with the graduations, being above the lid of the outer box ; the bulb of the thermometer rests in a cup, formed in a brass bar of the same dimensions as the bifilar magnet ; the brass bar is supported on a wooden stand, and lies parallel to the magnet ; the bulb of the thermometer is also covered loosely by a small brass cap. Tt was found from comparative observations (p. xxx., Introduction, 1843) that a thermometer, with its bulb free, would differ 1° from the thermometer resting in the brass bar in the course of a daily change of 10° of temperature. The whole in- strument was covered with a double thick cotton cover Jan. 31‘6" 1844. The read- ing telescope is fixed to a stone pier, 8 feet south of the magnet. 31. In the adjustment of the instrument, the magnet is forced to a position at right angles to the magnetic meridian, by turning the arms of the torsion circle. As, in forcing the magnet from the meridian, the upper extremities of the wire will move through a greater angle than the lower extremities, the wires will be no longer vertical, and the magnet and appendages will be raised; the forces producing equi- librium will, therefore, be the weight suspended endeavouring to attain the lowest point, and the horizontal component of the earth’s magnetic intensity acting on the free magnetism of the bar. 32. If v be the excess of the angular motion of the arms of the torsion circle, or upper extremities of the wire, over u, that of the lower extremity or magnetic bar in moving the latter from the meridian, the equation of equilibrium will be 2 . a . m X sin u = W sin v m, X, W, a, and I being respectively the magnetic moment of the bar, the hori- zontal component of the earth’s magnetic force, the weight suspended, the interval, and the length of the wires.

It is assumed, in the previous investigation, that the suspending wire does not act by any inherent elastic force ; that the torsion force depends wholly on the length and interval of the two portions of the wire and the angle of twist: it seems extremely probable that this condition will not be rigorously sustained, and it is very possible that there may be considerable twist in the suspending wire or thread ; BIFILAR OR HORIZONTAL ForcE MAGNETOMETER.

When the observations for 1843 were nearly through the press, observations of deflections of the bifilar magnet were made at two distances; observations of deflection of a unifilar magnet were also made; the dimensions of the bifilar and unifilar bars were very different, but, as the results for the two distances computed by equation (2.) were very nearly equal, it was considered that the differences be- tween p, q, and p,, qi, might be neglected; the abstracts were accordingly formed with the aid of the coefficient so obtained. It was discovered, after the volume was published, that the difference of the distances employed was too small to exhibit the error of the assumption that p=p,, &e. In consequence of this error, the coefficient has been redetermined by different methods, as follow :— 36. Wooden beams having been placed in the prolongations of the bifilar mag- net, and at right angles to these, lines were drawn upon them, passing through the centre of the magnet,—one in the magnetic meridian, the other at right angles to it; several distances from the centre of the suspended magnet were marked off on each side with a beam compass; a similar structure was erected for the declinome- ter. The following observations were then made :— lst, A cylindrical magnet, 3-65 inches long, was employed to deflect the bifilar and declinometer magnets; these two magnets are of the same dimensions, 15 inches long, and were obtained at the same time from the same maker. The short de- flecting bar was placed at different distances to the east, and at the same distances to the west, of the bifilar bar, and the deflections of the bifilar were observed in scale divisions. Observations of deflection of the declinometer magnet were then obtained with the same deflector—the deflector, however, being placed at the same distances, as in the other case, to the north and south of the declinometer magnet : in both cases, the prolongation of the suspended bar, in its normal position, passes through the centre of the deflector. The results are obtained in the 1st portion of Table 4. 2d, The same deflecting bar was placed to the north and south of the bifilar magnet, and to the east and west of the declinometer magnet, the prolongation of the axis of the deflector in both eases passing through the centre of the suspended bar. The results are given in the 2d portion of Table 4. 3d, A large deflecting bar (15 inches long) was employed in the same manner as the small bar im the 1st instance. 4th, The large deflecting bar was employed in the same manner as the small bar in the 2d case. In the 3d ease, deflections of the bifilar could only be obtained to the E, and, in the 4th case, to the S of the bifilar magnet, owing to the proximity of the bifilar to the walls of the Observatory. It was easy, however, from the observations with the small bar to make the requisite corrections for the difference of deflection on the opposite sides: the correction is small. The results for the 3d and 4th cases are contained in the 3d and 4th portions of Table 4. BIFILAR OR HorizONTAL Force MAGNETOMETER.

XXXIX 48. 1st, The first conclusion that may be obtained from this Table is, that after the needle has been vibrated by any means through a large are, its time of vibra- tion has been increased ; this will be apparent from the observations of vibration before and after April 304 74, July 244 184, July 264 38, November 54, and Novem- ber 8421, On all these occasions the needle was vibrated through large ares, either from the accidental approach of iron, or from the removal of the box for a short period.* 49. 2d, It is at once obvious, that the time of vibration depends upon the temperature of the needle, a change of + 1° of temperature causing a change of from +0505 to 0s10 in the time of one vibration. The amount of change in the time of vibration, for 1° of temperature can only be determined from the changes within short periods, since, 50. 3d, The time of vibration diminishes with time. The balance needle was adjusted, Jan. 27, 1844, the times of vibration after the adjustment were Feb. 1°— 6% Mean time of one vibration, 95:24 Temperature of needle, 33°-9 TS) I Rc 0.005 COCR oP ecco SE GDM rs cate Sevan pasc aisctiee 32°-0 Dee: 7 959==209 -) PaReee dees. ndotdees. DOMME: seagate! teh cote de 33°°7 The temperature of the needle is nearly the same in these cases ; it appears, therefore, that the time of vibration has diminished fully two seconds in ten months. This diminution is altogether independent of any variation in the magnetic moment of the needle, since the time of vibration in a horizontal plane remains nearly con- stant. During the same period, the mean position of the needle had varied about 160 micrometer divisions. «Since the position of the needle also varies with temperature, it does not at first appear improbable that the variation in the time of vibration is due to the varying position alone. Increasing temperature at the same time raises the north end of the needle and increases the time of vibration ; trom the beginning of 1844 till 1846, however, the north end of the needle has been rising, while the time of vibration has been diminishing. It is certain, from other observations, that the time of vibration is nearly constant for any angle which the magnetic axis of the balance needle makes with the horizontal. During a considerable magnetic dis- turbance, April 17%, 1844, observations of vibration were obtained for positions of the balance needle varying 400 micrometer divisions, yet the observed time of vibration only varied four-tenths of a second, and that not directly with the inclination of the needle, but from errors of observation and variation of temperature. Such a variation of position, if due to temperature alone, would have required a change of 50° Fahr., which would have produced a change of about 3°°8, in the time of vibration. * See Transactions of the Royal Society, Edinburgh, vol. xvi., p. 69, Table I. + Ibid., p. 72, Table IV. xl INTRODUCTION TO THE MAKERSTOUN OBSERVATIONS, 1844. 51. In order to determine more distinctly whether change of inclination of the magnetic axis affected the time of vibration to any considerable extent, the follow- ing observations were made during an adjustment of the instrument. January 18, 1848. The balance needle with its magnetic axis in the magnetic meridian, nearly horizontal, mean position + 160 mic. div. Arc of vibration at commencement, 32’. Time of one vibration, 8°-05. After this observation, turned out the horizontal screw one revolution, which changed the reading from + 160 mic. div. to — 818 mic. div. Are of vibration at commencement, 32’. Time of one vibration, 8°12. The horizontal serew was now turned in two revolutions, or one revolution farther in than at first, when the reading was changed from — 818 mic. div. to + 1120 mic, div. Are of vibration at commencement, 21’. Time of one vibration, 8°00. Finally, the horizontal screw was turned out one revolution, as at first, the mean reading becoming as at first + 160 mic. div., when Are of vibration at commencement, 32’. Time of one vibration, 85-12. 52. These results are very consistent, and speak much in favour of the excel- lence of the knife edges of the axle. It is quite certain, therefore, that the varia- tions in the time of vibration observed in 1844, were not due to the varying position of the needle, since all the observations in Table 5, were obthined from the needle when in positions varying less than 400 micrometer divisions. 53. As it was believed, that during considerable disturbances when the hori- zontal component of the earth’s magnetism increased considerably, the north end of the needle might be drawn slightly out of its position at right angles to the mag- netic meridian, the following observations were made to determine whether such a result would affect the time of vibration, January 14° 1848. The balance needle being placed on its agate planes with its magnetic axis at right angles to the magnetic meridian, the following observation was made; position of needle, micrometer reading + 180. Are of vibration at commencement 84. Time of one vibration 115-27. Needle vibrated excessively by a pair of magnetic scissors. Are of vibration at commencement 48. Time of one vibration 11°28. Brought a 4-inch deflecting magnet close to the side of the balance box near the west extremity, in order to draw the needle out of the plane at right angles to BIFILAR OR HoRIZONTAL ForcE MAGNETOMETER. xhi the magnetic meridian ; after considerable vibration, always checked by changing the position of the deflector, the following observation was made : Arce of vibration at commencement 30. Time of one vibration 115-28. Performed the same operation with the deflector, and again observed, Are of vibration at commencement 8-0. Time of one vibration 11512. Now lifted the needle by the Ys, lowered it, and observed the time of vibration with a large arc. Are of vibration at commencement 1000. Time of one vibration 115-27. Again vibrated the needle by means of the deflector placed at the side of the needle near its east extremity, so as to displace the needle from the plane at right angles to the magnetic meridian, and observed time of vibration, Are of vibration at commencement 900. Time of one vibration 115-29. None of these operations seemed to alter the time of vibration to any distinct amount ; the box was accordingly lifted off, and the needle was placed about 3° out of the plane at right angles to the magnetic meridian, the north pole (i.e. west ex- tremity) being moved towards the north, the following observation was then made : Arc of vibration at commencement 90. Time of one vibration 10558. Although the time of vibration in this position differs somewhat from that in the normal position, the previous observations prove that any deviations due to natural changes of force, would be insufficient to cause the differences evident in Table 5. 54. 4th, It was found in 1844 and 1845, that the time of vibration depended greatly upon the arc of vibration, the time being greatest for large arcs. (See Trans. Roy. Soc. Ed., vol. xvi., p. 70, Table IT.) 55. It is difficult, if not impossible, to offer any explanation of the anomalies in the time of vibration noted above, the knife-edged axle is a fruitful resource in instruments of this class, for the explanation of all difficulties. In this case, the needle is by the best maker (Ropinson) ; when examined by a lens, the knife edge appears perfect, and finally, the anomalies disappear at certain times without any apparent difference in the state of the instrument ; thus, in the observations already given, Jan. 14, 1848, the time of vibration for an arc of 3’ is exactly the same as for an arc of 100’; the observations also for the time of vibration with the needle differently inclined to the horizontal (Jan. 18, 1848), speak distinctly in favour of the excellence of the knife edges. It should also be remarked, that previously to the adjustment, Jan. 27, 1844, the curious effect of temperature upon the time of MAG. AND MET. OBS., 1844. l xhi INTRODUCTION TO THE MAKERSTOUN OBSERVATIONS, 1844. vibration was scarcely exhibited ; and it may be added, that in eight months since the needle has been adjusted with its axis in the magnetic meridian, the time of vibra- tion appears to remain nearly constant and equally independent of temperature and are of vibration. 56. It appears certain from these results, obtained from an instrument of the best character, treated with the greatest care, that the time of vibration in a vertical plane cannot be depended on as an element in the reduction of the observations of the balance magnetometer. 57. The question still remains, to what extent these anomalies in the time of vibration affect the observations for the varying vertical component of the magnetic force? The following fact appears to render it certain that they have no effect whatever. In determining, by the method of comparisons (see pages 1. and li.), the effect of a change of 1° Fahr. upon the position of the needle, it has been found that this effect is nearly constant, while the time of vibration in the vertical plane has varied from upwards of 11 seconds in 1843, to less than 6 seconds in 1846 (No. 77, 3d); the differences of the results for the temperature coefficient being in all probability due to considerable changes of vertical force in the periods selected for the determinations, and certainly having no relation whatever to the varying time of vibration. Since the temperature coefficient in micrometer divisions (q’) has remained constant, it follows that the coefficient of reduction (/) must also be constant. This conclusion renders it the more desirable that the value of the angu- lar motion of the needle in parts of the vertical component should be determined by another method which does not involve the time of vibration; the statical method already described for the bifilar magnetometer, has been employed for this purpose with some modification. 58. January 6, 1848. Wooden beams having been placed horizontally at right angles to the magnetic meridian, and a line having been drawn upon them, which was a projection of the prolongations of the balance needle, a small deflecting bar (3°65 inch long, and having a temperature coefficient = 0000285), was placed verti- cally at different distances on the beam, and the angeles of deflection of the needle were observed ; the centre of the deflecting bar was in the prolongation of the axis of the balance needle when horizontal, and the distances were measured from the knife edges of the axle, which, however, was found not to be the centre of magnetism of the needle. The resulting deflections and values of & for each distance will be found Table 6. January 10, 1848, the balance needle was taken out of its box, and attached to the brass detorsion bar of the declinometer ; the brass bar was mounted with a glass scale and lens, and was suspended in the declinometer box ; the balance needle was then deflected by the bar used for the previous deflections, which was placed to the north and south of the suspended needle, so that in both series of deflections the prolongation of the balance needle in its normal position passed through the centre of the deflecting bar. The deflections for three distances are given, Table 7.

The adopted value of & for the balance magnet =0:0000100 This value of one micrometer division in parts of the whole vertical component may be considered applicable to all the observations of the balance magnet since 1841: it has been used in the abstracts of results for the present volume. 60.

All the observations of the balance made between Dec. 31, 1843 and January 27, 1844 have been corrected by — 37-0 mic. div. 62. The observations of the balance magnetometer are made in the following manner :—The moveable wire of the right micrometer is made to bisect the spider- cross half the time of vibration in the vertical plane before the minute of observation, and that of the left micrometer as long after the minute; the mean of the two read- ings gives the position of the needle at the minute. The readings increase posi- tively when the north pole of the needle moves below’the horizontal. The quantities given, pages 1 to 157, are obtained thus: n being the observed reading of the needle (generally negative), ¢ that of the thermometer, giving the temperature of the needle, q the temperature coefficient in micrometer divisions =7-90, and R the quantity in the column, “‘ Balance Corrected” R = 700 + ¢ (¢— 26) +; increasing tabular values, therefore, indicate increasing vertical force.

The temperature coefficient of the large deflecting bar (15 inches long), used in the observations for the absolute horizontal intensity, was determined November 11, 1843, by hot and cold water experiments, see pages xlii. and xhii., Introduction 1843, for the details: the mean of all the observations gave The correction for 1° of Fahr., g = 0:000288 MAG.

The observations from which this result was obtained were very good, con- sidering that the whole angle of deflection was less than 3°, and it may therefore be worth examining the individual results for the highest and lowest temperature. The whole number of results was 15, the mean difference, from the final result given above, =0:000025, and the probable error of a single result was therefore about 0-000021.

See page xli., Introduc- tion, 1841-2, for the details. The whole number of results was 30: the mean gave The correction for 1° Fahr., Q@ = 0:000294. 66. If the 27th and 28th,results (counting from the top of the iast column of Table 19, p. xli., Introduction, 1841-2) be rejected, as it is believed that the great difference of both from the mean was probably due to one error in reading, we find the average difference of the 28 results from the mean = 0-000021, and the probable error of a single result was therefore about 0:000017. Combining the results from high temperatures together, and similarly for those from low temperatures, we find The mean of 15 results for the mean temperature 48°:0 gaye @ = 0:000292 Ther meawoly USecs avy. qeccseersssebbeswdveelsanets o~' seelOS27 tues Q = 0:000295 so that for the bifilar magnet, also, the temperature coefficient is constant within the ordinary temperatures of 32° to 80° Fahr. 67. The correction for the expansion of the silver wires and brass grooved wheel, =0-000010, being added to the value of Q above, we have The temperature correction for 1° Fahr., from hot and cold water experiments, g = 0:000304. 68. As the observations in connection with the balance needle had shewn that there might exist variations due to temperature, other than those due to the varia- tion of the magnetic moment of the magnet, such as the varying elasticity of the suspending wire of the bifilar magnet, the temperature coefficient was determined in the following manner, which had at first been found to give consistent results for the balance needle. TEMPERATURE COEFFICIENT OF THE BIFILAR MAGNET. xlvii 69. A series of days being selected in which the magnetic irregularities are small, and in which the variations of temperature are as considerable as possible, if we compare the mean instrumental readings for any two days, and if a R be the difference in scale divisions, this difference is due to change of temperature of the magnet, and to change of the horizontal component of the earth’s magnetism, let the portion of change of reading due to the former = A, and to the latter = A X, so that AR=A +4 AX. If the difference of the mean temperatures of the magnet for the same two days be a¢, then the correction for 1° of temperature in scale divisions whence Let a series of such values be obtained by comparing the mean scale reading, and mean temperature of the magnet for each day with those for each day following in the period selected : if we consider the differences a ¢ positive, when the succeeding day’s mean temperature is less than that for the preceding day, and sum the whole number of differences for which a ¢ is positive,* then If we neglect the last member, the whole error of the determination of 9’ will depend on the sum of variations of the mean horizontal force = 4 X ; asin asufficient number of determinations, it is probable that these variations will be as much posi- tive as negative, and, therefore that the numerator will nearly vanish, the last mem- ber may be neglected in the determination of q’, and this with the more accuracy the larger the sum of the differences of temperature a ¢. Again, if the differences for which a ¢ is negative are summed, we shall have _2aR TAX =I es ae Y The sign of the first member on the right remains as before, since a R also changes sign. 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 * Tf 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 = A R. xlviil 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 g 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 8, . . . . or 14 days’ interval. 71. 2d, That the value of g’ 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 g 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.

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 1s 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., xliii., and xliv., Introduction, 1841-2, for the details. The mean of the whole observations, properly weighted, gave q = 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 q’, 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 gy 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., xlvii., xlviii., and xlix., Introduction, 1843. It was found from these comparisons, lst, That the value of g’, when a sufficient number of comparisons had been obtained, was independent of the interval between the days compared. 2d, That the value of q’ 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 g’ 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 xlvii. and xlviii., gave g = 7:90 micrometer divisions ; and adopting the value of &, obtained from deflections, No. 59, q = 0000079. Which result is only 7 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 k ; this, however, is not always the case. The observations for 1845, 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 ¢ = 7-90 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 g would be less than 8:00 mic. div. The excellent series, November 30—De- cember 26, 1846 (after an adjustment July 1846) gives hi INTRODUCTION TO THE MAKERSTOUN OBSERVATIONS, 1844. gq = 772 mice. 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. lst, 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 94 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 l’ 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 asmall 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 | 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. hii 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, ? 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 Newman for the Duke 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 Dur 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 ScuuMAcHER’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 a a are by Apiz 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. lvil 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 NeEwMan,—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 :— Newman's standard, 32°:00. Dry bulb, 32°8. Wet bulb, 32°-7. Similar comparisons, September 4, 1844, gave NeEwmMAn’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.

The maximum and minimum self-registering thermometers, on RUTHER- FORD’s construction, were made by Apre 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.

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 ot 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 jomed 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 seale are equal to 55linches. 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.

INTRODUCTION TO MAKERSTOUN OBSERVATIONS, 1844. — 7) Giving the last result two values, we find, from both determinations, Proportion of whole heat stopped by glass plate A, =0:226. 96. 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 61 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 levelofthe sea. This gauge is sheltered to the KE. 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 63 feet above the soil, 171 feet above the level of the sea, and about 620 feet N. by E. of the Obser- yatory gauge. The funnel is connected with a graduated tube. The greenhouse and garden gauges were observed by Mr MacGatt, 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. lxi 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. Ap1z, 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, ¢ 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 f, whose axle rests on friction- rollers at g and h; 7 is a spiral, which has a cord wrapped onit carrying a weight £, which balances the vessel ¢; J is a dial, graduated \ on the face near the circumference ; m an in- 1 dex, attached to the common axle of the wheel and spiral ; ” a loose index under the | index m, which the latter carries forward by means of a projecting pin near the extre- ——~ (SIS Fant a ee mity; 0 a tube passing under the cistern a, which, entering the bottom,proceeds upwards within the vessel e 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 q rests or turns ; the tube 0 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.

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 surface 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 e on which the wind presses is 78 square inches, therefore a pressure of 1 1b. on this surface is equivalent to 144 Ib. 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 radius 7 = ae 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 m 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, is 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 Forzes. It is easily shewn that if the vessel e be homogeneous, w being the weight of a ring whose depth is one inch, P the pressure which the wind exerts on the top of ¢ diminishing its weight, 6 the corresponding are through which the circumference of the wheel fmoves (or the length of cord wrapped on the wheel), W the weight of the counterpoise k, and ¢ the specific gravity of the material (zine) of which e is formed, then W 2) mee ml a constant ratio, Cock. [xiii 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 Den? 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 Tuomas BrisBANE, by myself, or by Mr Wetsu. 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, Ixiv 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 k& of one scale division of the bifilar magnetometer, the whole horizontal component being unity (see No. 38), and the value of & of one micrometer division of the balance magnetometer, the whole vertical component being unity, are also given ; the value of the latter given here, 0:0000085, 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. Extra 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. lxv 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 1}™ 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 til] 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.

The readings of the barometer (corrected to 32° Fahr.) and of the dry and wet bulb thermometers, together with meteorological remarks, are given in the foot-notes ; other observations will be found in their proper places among the hourly observations. 114. Additional meteorological notes are given after the observations of the actinometer ; these consist of observations of shooting stars, thunder-storms, auroral clouds, dates of flowering of plants, times of the commencement of the morning-song of birds, &c. . 115. Abstracts of Results, pages 329-447. These Tables have appended or prefixed to them all requisite explanations, together with remarks on the conclusions deduced. 116. Curves of Term-Day Observations, Se. 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 III., 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.

Feb. 11 Feb. 22 March 2 March 7 March 9 March 12 March 29 Faint auroral light? 14" 5™. Faint auroral light ? Very faint auroral (?) light to NNW. Sky milky to W. Aurora? Bright moonlight. Band of auroral light to N. 85 30™. Brightest to N by W.; streamers from NNE. 9" 0™, Auroral arch about 5° altitude. Faint streamers from N by W. 9" 35™, Streamers. Rather bright auroral light to N. Faint auroral light. 385™. Auroral light gone. 125 Om. Clear to N., and no aurora visible. Evidently a bright aurora, with streamers, but scarcely visible on account of the bright moonlight. Fine auroral arch. Azimuths of extremities 35° and 286°, counting from N. to E., S., and W. ; altitude of lower distinct edge 11°; breadth of the luminous arch at the magnetic meridian Des Pencils of aurora within the arch at the azimuth 327°. Lunar corona. Yellow portion 2°°7 diameter. The auroral arch has fallen in at azimuth 340°; it has a cycloidal termination at azimuth 301°, and slopes off gradually to E. Faint streamers due N. Much of the inner edge of the arch is now nearly a straight line. Faint streamers continue at the N. Arch brightest at azimuth of 317°. Auroral arch fainter ; cycloidal termination at azimuth 322°; the arch slopes gradually from the meri- dian to near the horizon at the eastern extremity, azimuth 30°. Pencils at azimuth 326°. 31™. Pencils at the W. extremity, azimuth 328°. Aurora much fainter, losing the character of an arch—nearly amorphous and fallen in at 0° azimuth, where there is a bright point ; patches of cloud cross from eastwards. Bright at 3° azimuth.

(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. 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. 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 haye 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 114, 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 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 E4S., 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 8S. or WSW. 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. 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. Dec. 31 15 10. The sky looks more milky to north than on other points.

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 haying 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.

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 haye 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 Kast. 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 seud moving from about SW. May 21 6 . Fine cirri; cirro-cumulous cirro-strati dropping in ragged fragments to SE.; cumuli and cumulo-strati; seud on SE. horizon; the ragged patches of cirro-cumuli are finely-rounded cumuli on the tops, and only ragged below; solar halo.

This storm differs considerably from any observed here previously; although there were large , i piles of cauliflower cumuli and cumulo-strati with scud throughout the day, yet there was none of q that tormented appearance which the clouds generally assume previously to and during a thunder- k storm, The scud seemed, as long as it could be observed, to move nearly from the same quarter, 8., ; a 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 7 others, seemed formed of a series of beads; some terminated in large balls enveloped in shect 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. | Sept. 26 13.

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 4 the observers the impression that this is a phenomenon of a very different kind. It is cer- | P 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.

The fact that there are certain days in each month during which the motion of the magnet seems to obey a simple and continuous law, while the disturbances which destroy the regularity on other days are so obviously discontinuous or intermittent, occurring very seldom in some months, points out a method which, if not wholly free from objection, has the advantage of simplicity, and offers, it appears to me, a very near approximation to the truth. This method consists simply in the selection of the days which comprehend the first class of motions. Having carefully examined the nature of the diurnal variation for each day, I at first selected in each month the 10 days on which the effect of the intermittent disturbances appeared to me least. In the same manner, the 5 days with the smallest apparent irregularity in each month were selected. As the mode in which these selections were made was to some extent arbitrary, I desired Mr Welsh to make similar selections independently. Upon comparison, it was found that there were 17 days in 120, and 13 days in 60, for which we differed, and that the difference in almost every case occurred on days of which the preferability was very doubtful. It will be very obvious, however, from the coincidences of the results for the 5 days and 10 days selected, that a difference in choice of a few nearly equally good days, is altogether immaterial. The following Table contains a list of the days selected, which differ only in three instances in each class from the ' selections at first made by myself, and employed in forming the Tables; the days adopted from Mr Welsh’s selection in preference to my own, were, March 1, for March 27; November 5, for November 8; December 25, for December 23, in the 10-day class: and April 12, for April 10; August 28, for August 21; Decem- ber 7, for December 3, in the 5-day class.

It will be observed, that this result differs from that obtained by means of the whole series, in placing the principal minimum in the morning, and in nearly obliterating the secondary maximum and minimum. The mean for the 120 days gives nearly the same result as that obtained from the 60 days’ observations; the former places the secondary maximum about 14 40™ a.m., and gives 0-15 as the amount of motion from the position of secondary minimum to that of secondary maximum. Although the secondary maximum were wholly wanting, there would still be distinct evidence of the action of a secondary cause in the inflections of the curve. Other differences between the results for the 60 days, and for the whole series, will be indicated immediately. The following Table contains the epochs of maxima and minima, deduced from the monthly means for the 10 days and 5 days respectively. TABLE X.—Epochs of Maxima and Minima of Magnetic Declination, obtained from the Ten-Day and Five-Day series of observations. January February March April May June July August September ‘October . November December mMOOCOCOeMHHOHOOF The epochs for both series are nearly the same; considering the 5-day series as most free from the effect _ of intermittent disturbances, we find the same law to hold with respect to the varying epoch of the principal maximum as has already been found from the whole series. The principal minimum occurs between 9" and 104 p.m. in the four months of November, December, January, February, and it is only in these months that two maxima and two minima are distinctly marked; in November and February the minima are nearly of equal value. The minimum in the remaining 8 months occurs between 6" and 9" a.m. Ranges of Mean Diurnal Variation.—The following are the ranges of the monthly mean diurnal yariation, as deduced from all the hourly observations, from the hourly observations in the 10 days and in the 5 days least affected by disturbances. - Jan.

In each lunation, the hourly observations nearest the moon’s transit of the meridian, were summed as 0, the next following as 1, and so on up to 23 or 24; when only 24 observations occurred between two successive transits, the observation nearest the second of the two transits was summed both as 24 and 0. The numbers in the first column are, therefore, 34ths of the moon’s hour angle from the meridian. Diurnal Variation with reference to the Moon’s Hour-Angle.—The separate lunations present considerable irregularities, as might be expected where the range of the variations is so small; an inspection, however, of the separate results, renders it extremely probable that the law of variation is somewhat different for the lunations in which the moon is in opposition north of the equator, and for those in which it is in opposition south of the equator. The variations have accordingly been determined for these two groups, namely, for the Ist, 2d, 3d, 10th, 11th, and 12th lunations, and for the remaining 6 summer lunations. In order to destroy the minor irregularities, the following means of variations are deduced, the mean for the moon on the meridian (0) being the mean of the three values for 24, 0, and 1, in the previous Table, and each of the other values being the mean of two :— Groups, 02 0™ 2h25m 465 20m 6b 15m 8b J]Om™ 105m 12h 0m 13h §5m 15550m 17) 45™ 19h 40m 21h 35m Winter, 0°24 0°62 0°99, 0°99. 1°07 1°19 1°18 0°92 0°66 0°15 0°00 = 024 Summer,0"52 0°78 0°55 0°45 0°31 0°65 0°89 0°51 0°00 0°17 0°57 8 0°45 1844, 0°22 0.54 (062 0°56 0°53 0°76 0°88 0°56 0-18 0°00 0°18 0°19 When the moon, therefore, is in opposition north of the equator, the diurnal variation of the magnetic declination due to its varying hour-angle consists of a maximum of westerly declination when the moon’s MAGNETIC DECLINATION. 343 hour-angle is 11", or an hour before its inferior transit, and of a minimum of westerly declination 4" 30™ before its superior transit. The range of the variations is less than 1-5. When the moon is in opposition south of the equator, the variation is double,—there are two maxima and two minima; the maxima have nearly equal values, one occurring immediately before the moon’s transit of the inferior meridian, the other about 2h 25™ after the superior transit. The principal minimum occurs about 4" 30™ after the inferior transit, and the secondary minimum about 4" before it. The range of the variations is about 1’-0. In the means for the whole 12 lunations, there are also two maxima and two minima; the principal maximum occurs about half an hour before the moon’s inferior transit, and the principal minimum about 6 hours before the superior transit ; the secondary maximum occurs about 4" 20™ after the superior transit, and the secondary minimum about 4 hours before the inferior transit. The range of the variations is about 17-0. 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 Iunation, 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.

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. it 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 0/1, the greatest difference being 0’-2 ; and for the 5-day series, the average difference is 0-2, and the greatest 046. 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. 4 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.

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.

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 oceurring a few days before it and a few days after it.

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, 146 13 days to 15 days, Moon farthest South, 1/:53 2) ine Bisa: 197 EH Ace LOE ee 158 Ge... 8 ee. 1°80 QO icra Rel sere 169 es.)

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.a.; 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 _andilrm. Had observations been made at the even Gottingen hours only, the maximum would have been ex- _ hibited at 11 p.m. Makerstoun mean time. OP whe a oan RESULTS OF MAKERSTOUN OBSERVATIONS, 1844.

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.

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 :— 12h dhay. 22 gh 4b 5h 6k 7h gh gh oh qyh yobybpy, 2h gh 4h 5h gh 7h gh gh | oh 1a, 586 58'S 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 G75 707 666 67-8 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 54 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 tormal 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 yionee 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 inereases 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. Each 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 perizci, 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" .m., and its minimum about 10" p.m., 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. Nov.

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— y2hybam, 2h 3h 4h 5b Gh 7h Qh Qh JOh JJb Oh]hpy.Qh Bh gh 5h Gh 7h gh Qh JQbh ]]b 38:5 39-2 47-5 50°0 44:3 50-6 57-0 58:9 64:3 69:1 66:6 64:6 69:7 65:3 62:1 59°6 58:3 51:9 48-4 47-1 38:2 41°7 38-2 39:2 The number is a maximum at about 11" a.m., and a minimum about 103" p.m. There are twice as many excursions to the west of the normal mean at 10" a.m., as there are to the east, and there are about three excursions to the east for two to the west at 10 p.m. Diurnal Variation of the Positive and Negative Means of Disturbance——Since the number of positive disturbances is greatest when the sums of their excursions are greatest, and least when the sums are least, it is still unknown whether the increase of the sums is solely due to the increase of the number of disturbances, or whether the average positive or negative excursion increases with the number. The following are the average positive and negative excursions for each hour, together with the average of all the disturbances, without respect to sign :— 12h ibam, 2h gh 4h 5h gh 7h gh gh 640k ah Ob iMpy, 2h gh 4h 65h gh) 67h gh) |6ogh «(0h Jah , , , , , , , ’ , , ’ , , , ‘ , , , , , , +1°29 145 151 1°53 1:75 1°85 1°93 1°92 1°93 2°10 1:97 1.85 1:86 1°76 1°86 1°76 1°58 1°36 1:20 1:02 0:89 0°84 0°98 0°85 — 231 216 1°95 168 1°52 1°30 0°94 0:91 0°82 0-90 0°82 O92 1:02 0°94 1°06 1°44 1°41 1°54 256 250 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°48 145 1°90 1°81 2°23 1:90 1:92 2:08 MAGNETIC DECLINATION. 351 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 104 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 ail 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 92 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 Luoyn 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- eulus of probabilities. The following Tables may be considered a contribution to the theory of the distribution of disturbances of the magnetic declination, with respect to the arithmetical means of all the observations.

Diurnal Variation of the Probable Error of an Observation of Magnetic Declination.—The following are probable errors of a single observation for each hour (without reference to month) from the monthly means at the corresponding hours, deduced from Table XXI. by a graphic interpolation.

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 5> 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 (1°5), and a secondary maximum about noon, being about 1°13. 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 5b a.m. or 5" p.m. Whena 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® * ENCKE on “‘ The Method of Least Squares.” aylor’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 05 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.

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 (0:0035) 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 QbQ5m 4bOOm Gb15m Bb]Om 10h hm 12hOm 13hH5m 15h 50m 172 45m 19h 40m Q]b 35m es } 0:000| 047 053 101 055 076 074 164 187 059 078 000 071 +) s 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 singular 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-day series of hourly observations, greater than that deduced from the whole series by } 0000189 } 0-000251 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 :— ¢ Jan. Feb, March. April. May. June. July. Aug. Sept. Oct. Noy. Dec. 10 days,—0-78 —2-47 —2685 —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 +0:01 —0-97 —1-:11 —4:03 —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. oss. 1844. 42 366 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. Effect of Disturbances on the Hourly Means of the Horizontal Component.—The following ‘Tables contain the differences for each month between the hourly means obtained from the whole hourly observations, and those from the selected series of 10 days and 4 days.

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 (45 10™ P.M.) ............+5 ......=0:000800 cago sanreGURCOGEROApG diminishing .....................2.05-- (11> 10™ p.m. and 2 10™ a.m.) =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 2 and 3 of the range of the mean diurnal variation, whereas in the case of the horizontal component it is only between 3 t and } 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.

The maximum of the positive effect occurs about 3" p.m., and of the negative effect immediately after midnight, while there is also a secondary positive maximum about 6" a.m., and minimum about 10° a.m.; whence, as in the analogous discussion for the magnetic declination, we may conclude, that the smallest disturbances obey the same diurnal law as the larger disturbances. 7 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 Bifilar 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 XXXV. shews that the average difference 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.

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 4% 40™ HorizoNTAL COMPONENT OF MAGNETIC FORCE. 371 p.m, and at 10 10™ a.m. ; minima at 6" 30™ a.m., and at 12 40™p.m. Although the greatest value occurs about 45 40™ p.m., the mean difference varies little from 45 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.

Where the principal maximum or minimum is distinctly marked the former is indicated above by + and the latter by — These epochs indicate that the diurnal law of variation of disturbances was different in different quarters of 1844, 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 Digerences.—The following are the numbers of differences in 100 which were positive :— Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Nov. Dec. 531 454-8" 601 52:1 525) 40°7 47°17 49°83 54:3 61:2 556 59:6 Whence the horizontal component was oftenest in excess of its monthly mean for the corresponding hours about October and March, when there were about 60 positive to 40 negative observations ; it was least often in excess about June, when there were about 46 positive to 54 negative observations. 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 Diferences—The number of positive differences in 100 for each hour of Makerstoun mean time in 1844 are as follow :— 12h hay, Qh gh gh 5h «gh |= 7h gh gh gh 17h Ob Ibpa. gh gh gh 5h gh 7h gh gh gh 1h 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 51:6 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 42 a.m. and 10" a.m. ; it is a principal minimum about 4 p.m. and a secondary minimum about 7# a.w. The number of positive differences is greater than the number of negative differences in each hour, excepting those from 3% till 7". Mean Disturbance. 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 Distwrbance.—The following are the mean disturbances for a single obser- yation in parts of the horizontal component in each month of 1844 :— Jan. Feb. March. April. May.

Diurnal Variation of the Positive and Negative Sums of Disturbances.—The following are the sums of dis- urbances in scale divisions for each hour in 1844. 12h Jam. 2h gh 4b 5h gh 7b sh gh 30h jib ob lbp. 2h 3h ah 5h 6h 7h gh oh 10h 11h +495 424 415 450 482 661 665 586 636 625 619 737 879 759 829 951 1090 1005 S841 726 685 488 504 425 —843 846 924 749 633 729 521 618 694 742 775 612 521 476 426 512 414 478 538 632 636 921 808 940 The sums of positive disturbances—those which increase the value of the horizontal component—are a “maximum at 4" 10™ p.m., and they are a minimum about 1" 30™ a.m.; there is the appearance of a secondary 372 Resuuts oF MAKERSTOUN OBSERVATIONS, 1844. maximum about 6" a.m., but it is not well marked. The sums of negative disturbances are a minimum about 3" 10™ pw, and a maximum about midnight; they are a secondary minimum at 6" 10™ 4.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. Diurnal Variation of the Mean Disturbance.—The following are the mean disturbances, in scale divisions for each hour, without regard to sign :— 125 1b aw 2h gh 4h 5h 6b val gh gh Joh ih Obyhpm. 2h gh 4h 5h 6h 7h gh gb yoh qyh $26 4:05 4:4] 3°82 3:55 4:43 3:78 3:83 4-24 4°35 4:44 4:30 4:46 3:93 4:00 4°66 4:79 4:72 4:39 4:32 421 4:49 4-18 4:35 These quantities give nearly the same law of variation as the mean differences ; the maximum disturbance of the horizontal component occurs at 4% 10™ p.m, the minimum about 5" a.m.; a secondary maximum occurs about 10" a.m., and a minimum about 1” p.m. Annual Variation of the number of Positive Distwrbances.—The following are the numbers per cent. of hourly observations in each month, which were positive or greater than the normal means at the corresponding hours :-— Jan. Feb. March. April. May. June, July. Aug. Sept. Oct. Nov. Dec. 54:0 57:7 66:0 52-1 52°6 45:0 46:6 52°8 55:2 60°6 56:9 61:1 The greatest number of positive disturbances occurs near the equinoxes, and the least number at the summer solstice; on the whole, the number for the sun south of the equator is greater than for the sun north of the equator, the number per cent. for the former being 58-4, and for the latter 50°7. 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 :-— Whibam, 2h gh 4h 5h 6h 7h gh gh 105 ah oh ihpaw, 2h 3h 4h 5h gb 7h gh gh 10h 11h 47-5 47°8 449 50°3 51:6 58°90 554 55:1 55:4 53:5 54:1 59:2 60:5 57-6 63:4 59°9 67-2 64:0 58°9 57:3 538 46-5 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 2" 4.m., 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 sums 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 :— 12hibamw, 2h 3h 4h 5h gk: 7h gh gh 10h 11h 19h jb py, gh sho 4h fh Gh 7h, «68h gh = oh 1th +332 283 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 —511 5:16 4°34 4:80 4:17 5°52 3:72 438 4:96 5:08 5:39 478 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.

VERTICAL COMPONENT OF MAGNETIC FORCE. 373 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 magnetic 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.m, being about 0-00050; the probable error is about 0:00034. Tn 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. The least probable errors are about 2" a.m. in these three months, being less than two ten-thousandths of the whole horizontal component. VERTICAL COMPONENT OF MAGNETIC FORCE.

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 :— ves “oa 4 0-00223. Where V is the reduced value of the mean for 1843, v 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.

From the above mean values of the variations, the vertical component is a minimum in August, and a maximum in December or January ; it is also a secondary minimum about the end of February, and a maximum again in April.

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 2 maximum when the horizontal component was a minimum.

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 5 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 hay- 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 im 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 principal maximum is indicated by + and the principal minimum by — ; the differences, however, between the values of the principal and secondary points are small, excepting perhaps for the months of December, January, and February. 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 -eonsider 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. 2; tr 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 occurs 4 hours before the moon’s inferior transit, and the principal maximum occurs 4} hours after the inferior transit; a secondary minimum occurs about 44 hours before the superior transit, and a secondary maximum at the superior transit. Tn the mean of the 12 lunations in 1844, the maximum occurs 3} hours after the inferior transit, and the minimum oceurs 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, differing from the monthly means at the corresponding hours by more than 50 micrometer divisions (=0-000500), quantities interpolated from the preceding and succeeding observations having been substituted. The following are the resulting variations at intervals of 24 of an hour:— 0 TF 2 8 4 4 6 7 Weiesmoeal 12 18 14°35 We) ay 18.919 20) Bh oe 0:0000 | 37 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 mimimum 7 hours after the superior transit; there is an ill-defined minimum about 3 hours before the superior transit, and maximum at the superior transit.

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 GO Maas oi vs ose sen qadigevcinshivents Sauceerpaae sine ideas teciaast 0:000015 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.

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" s.m., and it is zero at 105 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 1} 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.)............0.0065 =0:000196 Siscemtiece motets diminishing’ -2.se-eeeeeecesseness5.

The differences for each month from both series of comparisons, give, with slight variation, the same times of maximum and minimum effect, the amount being greatest at the equinoxes. The following are the differences between the hourly means for the 120-day series, and those for the 60-day series, or means for 120 days minus means for 60 days.

The maximum positive effect oceurs about 535 p.m., and the maximum negative about 1" a.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 Howrs,—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.

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 :— yah yhas, 2h gh 4h 5h gh 7h gh gh ggh ab gh lbp, 2h gh 4h 5h gh 7h gh | gh yh yh 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 42:5 The number of positive disturbances is a maximum about 5" p.m., and a minimum about 1" 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. Diurnal Variation of the Positive and Negative Means of Disturbance——Dividing the sums of positive and negative disturbances by their respective numbers, we have the following means :— 12h thaws. 2h gh 4b a gh 10h 11h 19h 1hpm. gh gh 4h 5h 6h 7 sh gh job 11h +97 11:3 9:3 9-5 10-0 10-4 10:3 10:4 10:0 12:1 116 14:8 19-1 18:4 19°8 26:3 28'7 31:6 32°2 26:1 19°6 14:3 10:9 10:0 —29'9 28-8 30-2 30:1 29-0 28:3 24-7 189 15°7 12:7 119108 96 97 11:0 93 98 88 88 85 10:0 15-4 205 22:5 These quantities give nearly the same results as have already been obtained for the sums of disturbances.

Note on the least probable error of an Observation of the Vertical Component.—Investigations similar to those ‘or the probable error of magnetic declination have not been made for this component. The mean difference, however, for an observation of the vertical component is least for the months of December and January, when zr is 12:3 micrometer divisions, and for the months of June and July, when it is 14:0 micrometer divisions. + MAG.

The probable error of an observation of the vertical component from the monthly mean for the corresponding hour will therefore be in pies or nay Bes: 000010 | 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. Maenetic Dire.

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.

Variations of Magnetic Dip with reference to the Moon’s Position in Declination The general appear- ance of the quantities in the second portion of Table LIV. is that of a maximum of magnetic dip when the moon is near the equator, and a minimum when it is farthest north and farthest south.

March. 392 RESULTS OF MAKERSTOUN OBSERVATIONS, 1844. Diurnal Variation of Magnetic Dip.—tIn the mean for the year the magnetic dip is a maximum at 10° 10™ a.m.; it has its least value at 5° 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.a, 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 XXVIII., 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 :— 12b 4b a.m. gh = gh 4h 5h 6h 7h gh gh job ah ob hp, 2h gh 4h 5h 6b qh gh gh oh yyb Series. 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 —O'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 O11 0°24 0°30 The means for both series give the same result ; the maximum of dip occurs at 105 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 magnetie declination for the year being 77, the motion in declination is rather greater than that in dip at Makerstoun. Ranges of the Mean Diurnal Variation of Magnetic Dip—tThe 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. Dee. 78 O82: 9:19 3-9) (B-4Oe arziy 1360 3:34). 2°86 244 Ish Oe: 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. Diurnal Variation of Magnetic Dip with reference to the Moon's Howr-Angle.—The following Table con- tains the variations of magnetic dip, as deduced from the last three columns of Tables XX XI. and XLVII. :— MAGNETIC Dip. 393 TABLE LVI.—Variations of Magnetic Dip, with reference to the Moon’s Hour-Angle, as deduced from Tables XX XI. and XLVII.

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 12 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 KXXI. and XLVII., from which the large disturbances have been removed, we have for the variations of dip for the year— OhOm = 2h 25m 4h 20m GR 15m = Sh 10m 1h Sm = 1QhOm = Bh 55m «15h 50m «7h 45m = 19h 40m =] b 35m 0104 0°087 0-030 0°062 0°045 0°068 0°001 0000 0"134 0°087 0157 0080 These quantities give nearly the same law as that obtained above, MAG.

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 865 and 384 :— The Mean Magnetic Dip, as deduced from the whole series of Hourly 120-day series, by 0175 Observations, is greater than that deduced from the............... 60-day series, by 07245 It has been found, p. 343, 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 observations of the bifilar magnetometer made at St Helena, in the four years, 1842-3-4—5, have been examined in asimilar 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 megnetic 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.—It is evident, from the first portion of Table LVII., 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 uae Full Moon, 0-000017 29 days to 1 day, New Moon, 0-000132 UTE cosncBe 20 0:000068 2 eisente 5 days, 0-000126 2A SEB AE Pe aa 0-000135 sarics aon 0-000133 2Din ease 28a. 0:000130 LOR neree IEE sre 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 13 days to 15 ae Moon farthest South, 0-000103 BS eBEoe 5 days, 0:000070 GS coca . 19 0:000091 Gigcces-e Sis 0-000060 Os wear 22) ¢ 0:000054 LE capanoris WF oaan 0:000054 BOF) cans A eae 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 XLII. KB COOnMDNANVRWNHeH OS _ TotTaAL MAGNETIC Force. 397 Diurnal Variation of the Total Magnetic Force.—In the mean for the year the total force is a principal maximum at 54 20™ p.m, and a principal minimum at 2" 10™ a.m.; it is a secondary maximum at 7" 10™ a.m. and a secondary minimum at 10 10™ 4.m. The range from the principal maximum to the principal mini- mum is 0:000490 ; the range from the secondary maximum to the secondary minimum is 0-000075, the total force being unity. 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 2" a.m. is best marked in all the remaining months of the year. The principal maximum occurs between 4" p.w 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.|[12h 18 Qh gh 4h 5h gh 7h gh gb 10h Jib] Joh yh gh gh gh 5h gh 7h gh gh 0b 11h| Par, 120-day, 0°000 | 144 135 140 149 158 172 174 164 133 088 038 038 062 138 201 250 285 306 307 298 283 256 222 180 60-day, 0°000|171 159 156 158 161 175 176 164 140 086 037 022 058 130 199 242 269 288 288 286 270 249 222 194 Both series give nearly the same result; the epochs of maxima and minima are as follow :— 120-day series, Principal Max. 5 50™ p.m. Secondary Min. 1» 30™ a.m. Secondary Max. 55 50™ a.m. Principal Min, 105 50™ a.m. 60-day series, .................. 5))50™ P.M. | 2 .caeeeeeenneee BY QUUTAGML: petveredauscseme SEO AGMS © edn eicoeotecuene 105 50™ a.m. The principal difference between the results for the complete and undisturbed series consists in the trans- ference of the epochs of principal and secondary minimum ; in the complete series the principal minimum occurs at 2" a.m., in the undisturbed series a slightly-marked secondary minimum occurs at that hour, but the principal minimum occurs about 11" a.m., nearly the time of the secondary minimum for the complete series. 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.

The elimination of the larger disturbances renders the variation for the year nearly similar in its epochs to that for the summer group; it is probable, therefore, that the differences between the variations for the summer and winter groups is chiefly due to disturbances.

Effect of Distwrbances on the Yearly Mean for the Total Magnetic Force.—We obtain the following results from the mean values of the horizontal and vertical components for the year, pages 365 and 384:— The mean total force, as deduced from the whole series of hourly observations 120-day series, by 0:000038 for the year, is less than that deduced from the--:-++ +++ +++ ese +eeeee eee see eee 60-day series, by 0-000089 Effect of Disturbances on the Monthly Mean of the Total Foree—Using the corrections for the two com- ponents of force, pages 365 and 384, we obtain the following quantities, corrections of the means of total force for each month obtained from the 10-day and 5-day series, to the means from the complete series :— Jan.

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 105 20™ a.m., and at 92 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 inereasing 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 aurorz 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 AURORA 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 aurore boreales seen at Makerstoun in 1844 was 26. The numbers seen in each month were as follow :— ee Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Noy. 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 thesé 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 solstices 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. 7 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 aurore is the same as that of the intensity * Mémoires de l’Académie Royale de Belgique, tome xx. Kimtz, 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. 199 962... 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. 44—114...2°62. 124— 189 Full Moon,... 3°43. 194— 262... 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 aurora 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 aurorz occurs between 8" and 11" p.at. 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, indeed, 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. Paint Aurora,............... 3 days before Full Moon. Sept. 27.

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 aurora 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. ABSTRACTS OF THE RESULTS OF THE METEOROLOGICAL OBSERVATIONS, MADE AT THE OBSERVATORY OF GENERAL SIR T. M. BRISBANE, Bakt., MAKERSTOUN. 1844, 404 RESULTS OF MAKERSTOUN OBSERVATIONS, 1844. 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 Géttingen 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 ihe remarks, the observation has been supposed to be made 10™ after the Makerstoun nee: and civil reckoning is used.

Annual Variation of Temperature.—The monthly means at the foot of Table I. are slightly different from the true monthly means, on account of the want of observations on the Sundays ; the difference, however, may be obtained with sufficient accuracy from the observations of the register maximum and minimum thermometers. The monthly mean temperatures deduced from all the observations of the register thermometers are as follow :— Jan. Feb. March, April. May. June. July. Aug. Sept. Oct. Nov. Dee. 36°06 32°73 38°73 47°25 48°27 55°20 56°06 55°63 52°86 46°36 42°07 32°.14 when the observations of the register thermometers on Sundays are omitted, the means are— 36°63 32°47 38°60 47°08 48°69 55°26 56°07 55°87 53°02 46°33 41°88 31°73 The differences between the two series are— 40°43 +0°26 +0°13 +0°17 +0°03 —0°06 —0°01 —0°24 —0°16 40°03 40°19 +041 TEMPERATURE OF THE AIR. 405 When these differences which are due to the temperatures on Sundays are applied as corrections to the means at the foot of Table I., we obtain the following as the mean temperatures for each month of 1844 :— Jan. Feb. March. April. May. June. July. Aug. Sept. Oct. Nov. Dec. 37°35 32°48 38°36 46°77 48°49 54°14 55°55 54°08 52°80 45°74 42°85 32°04 The temperature of the air in 1844 was a maximum in July and a minimum in December and February. 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. Feb. March. April. May. June. July. Aug. Sept. Oct. Nov. Dec. 4°30 4°20 4°48 2°62 2°69 3°00 3°33 1°62 2°07 4°50 3°90 3°20 The difference is least in the months during which the sun is north of the equator: the mean for the six winter months, October—March, being 4°09, and for the six summer months, April—September, being 2°55. The ofcillations of the daily mean temperature do not appear to be at all related to the variations of the diur- nal range. Approwimations 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-registering thermo- meters by the formule m, + m, ike (Cate aM 9 +M meres ws BORE oa SAT Ee 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 changes of temperature between 115 10™ 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 12h 10™ a.m., minus temperature at 11> 10™ p.m. :— Jan.

This result was obtained from the two hourly observations for 18438, p. 265. In order to examine the variations of temperature about midnight in the winter group, we may connect the mean at 12 with that at 11", by means of the corrections given above; from these, the mean at 12" in winter is greater than the mean at 11", by 0°08; from this, and the above means for the winter group, we find the variations of temperature from 95 10™ p.m., till 3" 10™, to be as follow :— gh 10% 11» 12h yh Qh gh 0°20 0°-00 0°16 0°24 0°31 0°17 0°01 From these, there appears to have been a secondary maximum of temperature in winter at 1" 10™ a.M., the secondary minimum occurring at 10" 10™ p.m. This result is exhibited in the means for each of the months November and December, and also in those for January, the true change from 11" to 12" being ‘considered. The maximum temperature for the year 1844 occurs at the same hour as for 1843,—namely, 1) 30™ p.m. The mean temperature for each month occurs at the following times :-— Jan. Feb. March. April. May.

By means of this measure, we find the values of the approximations to be in the following order, commencing with the highest :— lst. 5"10™am.,and 4510™p.m, 2d. 9540™4.m., and 10>10™p.m. 3d. 9° 40™4.m.,and 9540™p.m, 4th. 10"10™ a.m.,and 11210™p.a, 5th.10"10™a.m., and 10®10™p.m. 6th. 5" 10™a.m., and 11" 10™,.m. 7th. 9210™4.m.,and 9"10™pm, 8th, 7°10™ p.m. 9th. Max. and Min. The best approximation to the mean for the year is given by the observations at 10> 10™ a.m. and 11" 10™ p.at., which differs only 0°01 from it. If the 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 10°10™ 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.

Diurnal Range of Temperature.—From the means at the foot of Table V., it appears that the mean of the diurnal ranges of temperature is less for the months about the summer solstice than for the months before and after them. The greatest mean ranges are those for April, May, and August; the least mean range is that for December. The mean of the ranges for the astronomical quarters, and for the year 1844, are as follow :— Winter, 8°-68 Spring, 14°40 Summer, 16°63 Autumn, 15°13 Year, 13°71 The mean ranges, as deduced from the minima and succeeding maxima of the register thermometers, are for each month as follow :— Jan.

Assuming that the change in the means from 11” to 12° is the same as from 10 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 eradual changes, the epochs of maxima and minima will be determined with more accuracy. Table XXII. has been formed in this way. The hourly means of the astronomical quarters having been obtained, the change from the preceding to the following 12 was found— in, in. in. in. For Winter, —+0:0131. Correction, =—0:00055 an hour.

Table XXYV. contains the means of the maximum pressures of wind recorded by the anemometer between the hours of observation: Table XXVI., 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.

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.) oceurs between noon and 2» 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 108 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 5" a.m., a secondary maximum occurring between these times ; in 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 35 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.

Dec. 233 308 382 371 275 400 306 434 442 459 459 176 The average numbers a-day out of 24 observations are 86 123 147 143 102 160 11:3 16-1 List 1750) 727 6°8 The wind blew most frequently in the months from August to November, and with least frequency in January and December. 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 number of Points of the Compass in which the Wind blew.—The following are the numbers of points in which the wind blew in each month of 1844 :— , Jan. Feb. March. April. May.

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.

PRESSURE AND DIRECTION OF THE WIND. 435 The first column of resultant means is obtained by dividing the resultant sums by the whole number of observations of 24 a-day ; the second column is obtained by dividing the resultant sums by the number of ob- servations for which the wind was blowing. Annual Variation of the Resultant Pressure of the Vind.—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 8. and W. in January, April, June, August, September, and October; between N. and E. in May; and between §, 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 from the diferent 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 1843) 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 1848 was as 1, 4, 8, and 16. 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. W. NW. N. NE. B. SE. s. lb, lb. Tb. Ib, Ib. lb. Ib. lb, 1104°7 643-4 358°6 277-7 452°3 219°8 160°6 302°4 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. W. NW. N. NE. K. SE. 8. Ib. lb. Ib. Ib. Ib. Ib. lb. Ib. 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 of Table XXXVI. was obtained from the observations for 1848, though not so distinctly. The direction of the 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 is 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, 7. ¢., at the time of maximum temperature. See remarks on the motions of the different currents, after Table XXXVII.

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 seud, 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 XXXVII.) for the differences seud 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 01 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 oe 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 li. to S., 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 conelude 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 obtamed 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 8. 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 Scud current minus surface current, from 347 results, ienis 1700 comparisons) = + 13°.9 Cirro-stratous current minus surface current, ... 228 ......

It happens frequently that comparisons of the motions of two currents are obtained when the other two do not exist, or are not evident, from the absence of clouds within them, or from the masses of clouds in the lower current, It is for these reasons that each of the comparisons of motions above are obtained from observations made partly at the same and partly at different times; they are therefore to a considerable extent independent MorTIons oF CLoupDs. 44] of each other; if this had not been the ease, the difference of motion cirro-stratus minus scud would have been the same when obtained from the several individual comparisons and from the final differences. The mean difference of the motions of the cirro-stratus minus scud from the individual comparisons = + 16°:4, but ob- tained from the two final results (cirro-stratus minus surface), minus (seud minus surface), it is = 21°7 —13°9= +7°8; similarly the difference cirrus minus scud from the individual comparisons = + 12°-8, but obtained from the results (cirrus minus surface), minus (scud minus surface), it is =31°9—13°-9 = + 18°-0. The difference of the results by the two methods is evidently due to the different observations from which they are obtained ; the law of sign is unaffected, the amount only is different. If we take the mean of the results for the comparisons of the three upper currents with the surface current, we find that 672 results give the mean upper current minus the surface current, = +19°-0 Similarly, if we combine the means for the comparisons of the cirrous and cirro-stratous currents with the scud current, we find that 323 results give the mean cirro-stratous and cirrous current minus the seud current, = +15%2 Tf we now examine the relative motions of the mean of the three upper currents, and of the surface current in each quadrant, we obtain the following results :— Quadrant N. to E., 142 results, mean upper current minus surface current, = + 4°3 iy ie one TONS pus tl eC OS Sree eccpogsedessesoadneer Me aiyten peaeooe 0 sds Ss fOl Vt. 3D SEE oe faciecns ccndacisr sauncmiarmese nee ck ase esi eT nO er W. to N., 136g geen...

This is the only case where such difference is found; the upper current is most positive of the lower current in the quadrant W. to N. It appears, then, that the mean upper current always proceeds from a point positive of the direction of the surface current, and that the motion of the mean highest current, with reference to the scud current, follows the same law, with one exception. This result is in accordance with the conclusions from the causes of the oblique motions of the aérial currents. Currents of air proceeding northwards from more southerly positions, retain a portion of the eastward velocity of the places from which they start ; hence the south-easterly winds become more southerly, and the south winds become more south-westerly as they proceed northwards, the extent of the change of direction depending on the greater or less rapidity with which they lose their excess of eastward velocity, and acquire that of the more northerly latitudes over which they move. This loss of eastward velocity will depend upon the proximity of the aérial stratum to the surface of the earth, and therefore the lower currents of air will lose more of their eastward velocity than the higher currents, and the upper current of southerly winds will become more westerly than the lower currents. If, in considering the currents of air which proceed southwards from more northerly latitudes, we remember that the lower currents, from their proximity to the surface of the earth, acquire the greater eastward velocity of the lower latitudes more quickly than the upper currents, it will be evident that the lower current from the north-west will become less northerly than the upper current, and that the lower current from the north will become less easterly than the upper current. There appears to be an excep- tion in the latter case: the highest current of air proceeds from a point less easterly than the middle current. It is believed that this anomaly is due to the following cause ;—it frequently happens that when the lower current of scud is from a north-easterly poimt there is an upper current of cirrus or cirro-stratus from a north- westerly point: these two currents cannot have had the same origin, and therefore the explanation of the dif- ferences of motions given above cannot apply.

This result only agrees with that for 1843, in having a maximum when the moon was farthest south. In order to obtain any connection between the age or position of the moon and extent of clouded sky, it will probably be desirable to consider only those observations made between 6" p.m. and 6? a.m, 444 RESULTS OF MAKERSTOUN OBSERVATIONS, 1844.

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- yatory-gauge is very distinctly marked. PRINTED BY NEILL AND COMPANY, EDINBURGH.
