Letfl,^,, ^3, be the mean leniperatiires of three /L^rtaips of days in chronological order, each group consisting of from one to iliree or four enden of and in addition to the effect on the magnetism of the mai,'net, would seem, in some instances at least, to be occasioned by a chang- piouuced by changes of tem[)eratme on tlu! flintribution of magnetism, and for which in the reduction of the experiments no allowance is usually made. If (m) be the magnetic moment of the magnet whose temperature coefficient (q) is sought by the ordinary hot and cold water cxp<'riments, (r) the distance between the magnetic centres of the suspended and deflecting magnets, (u) the angle of deflection, X the horizontal component of the force ; the relation between m, r, u and X will be given by the formula Viil TNTRODrCTION. m "/(r) X n\n «, j wh«'r«'/(r) \n w»m«« fiim'tion of r | and thf ri'lntion betwopn \\w.\r Nimultnni'oiiM Mtimll chimKi'N by A'" fir) » , . . , AX '«" TT^) •"' + ""* "'""^■^- Now if '" hr tin* rt'lntivi' inrr)>n«c in the mnKnclIc moment dui» to a (lecr<«nMf of / — /„ dngrpt^it //( in the tomponitiiri', iind 7 tliiii »iiu' toudt'oreiisn'of on«(l«'f(r»'e, «otlmt ' ■■ tf {I — f„) thtt preceding «><|iiaiity will ht'Coiiit> SiippoHo till! north oncl <>f the (Idlcrtor to ho nrarnNl tndud iiirif^nct, und that 11 dt'creuHe of one dt'grco in the trm porn lure cihiwh tht; inagni'lio ionlri' to rocfilo from tht north und liy tho Hmall tjiiantity (n), ho that Ar = {I — '„)'i; iilso Id 7, ho iho valno of 7 caloiilated {\a oonforinity with tho ordinary practiou) on Iho MnppoMiiion ihut r in lutiiMtant, or that Sr ^>0 \ wo mIiuII tiiun have Similarly if 7^ bo the valuo of 7 similarly dorivod from oxpcrimcntM mndo with the south end of the dctieclor presented, whence 7= i? 7i +7a | ; or the tomporiiliiro coellioient 7 will be the arithiiietie mean iMJtween 71 and 7,^, the vnlucB derived from exporiinonts in which the north and south poloH of the dolloctor rospeotively are presented.

Now from the observations with the instrument during the pctriod to wliieli the foregoing value of k relates, the ecjuivalent in scale readings for 1" of temperature — = O-flO. The agreement between and '^ though not perfect, in much closer than if 7, had been adopted as the true value of 7, and which, it may be noticed, agrees very nearly with the results of a scries of experiments in 1843 and of another series in 1845, which gave resptictivcly q = 0001032 and 7 = 0001138.

(2) For the several instruments, normal scale readings for each observation hour were calculated, by taking tlie average of all the reading;, at like hours in a month, or more suitable group of conscou- tive days, omitting the larger disturbances, or such readings as dillercd from the normal finally adoptcdfby an amount equivalent to tiie limit employed by General -abine in tiie third volume of the "Toronto Observations," namely, 5.0 for the declination, .0012 for the horizontal force, and .00026 for the vertical force. (3) The mean of the six normals, or the six-hour daily mean normal, was then employed as a standard of reference for tlie six-hour ■ ily means of each day included in the group from which the normal was derived. The six-hour daily mean normal being subtracted from each six-hour daily mean, the remainders (expressed in minutes for the declination, and in parts of the horizontal and vertical components of the force) gave the abnormal deviations of the daily means; the sign (+) in- dicating an easterly deviation of declination, and a deviation of the force in excess, and the sign ( — ) indicating an opposite deviation. INTRODUCTION. XI t to the ted. Ihf he 26 (4) From the six-hour daily mean normals were then obtained the twenty-four-hour daily mean normals, by applying the corrections for diurnal variation deduced from the tables in pp. 90-92 of " Toronto Observations," vol. iii. (5) The twenty-four-hour mean normals bring then subtracted from the normals of each observa- tion hour, the remainders reduced by the scale coefficients gave the diurnal variations at each observa- tion hour, as furnished by the several instruments. (6) The abnormal deviations of the dally means and the diurnal variations of the horizontal force, where the observations of more than one bifiiar have been employed, have been regarded as equal to the means of the corresponding numbers given by the two or the three bifilars.* (7) The abnormal deviations of the daily means and the diurnal variations of the total force [^i) and inclination (6), were calculated from those of the horizontal and vertical forces (X and Y), by the formulte 9 '^ in'd AY M = 5- fin 20 AY Y ^\ (8) In collecting the disturbances of the horizontal force, where the results furnished by more than one hifdar have been combined, the eomliination has been ellecled as follows. The normals for each bifilar being found in the usual way, tiie dillerences theri'from of the disturbed readings, and ex])ressed in parts of the horizontal force, were ph\ced in parallel columns and in chronological order. In the great majority of ohservalions, where one instrument gave- a disUirbed reading the olliers did so also ; but when this was not the case the blank was filled up wilh the difference, whatever it might be, between il " observed reading and the corresponding nornuil. The means of the two or the three corresponding cnlries in the ditlirenl columns being then computed, those were retained as distur- bances which equalled or exceeded .0012. (9) The disturbances of the horizontal and vertical componenis of the force being found, the cor- responding abnormal deviation A"^, of the total force, and AO, ol the inclination, were calculated by the formula; AY ^ = C08 = ^ -, .\ - + sm^'O ( AY AO = ' sin 20 ] -~- "! A V . A Y where -^- and ,,- represent the contemporaneous abnormal deviations of the horizontal and vertical components of the force where one or both of them are disturbed. • The obscrvaliona hy tlio sniiill l)iflliir nnil liy IJnniilcls' liilllar have been commonly iisod in conjunction in tlie compntation of the tMles, I)nt those furnished hy one or other of tliese instiunuiits huve l)ecn excluded from the nhimrmal variiition t)f dnily means when a break has occurred in the course of the nuinth, sucli as to rocpiire tlie daily means in two portions of the month to be re- ferred to diU'orent nornials. In cakulatMi>; the dislnrhauce of the horizontal force, the numbers supplied by one of these bililars only has been employed when an instrumental change has taken place in the other bililar, rcspectinff the precise epoch of whoso occurrence any doubt has existed, so as to render the results (;iveii by one instrument more worthy of conlidence than that derived from the combination of the tno. Several exclusions of lliis kind occurred with the small bifilar, most of which were in 165G, nnd Bone few in 18.17, 185S, and 1859. Hrooke's bililar has been combined with the other two bifilars in computing the disturbances in 1661, and the abnormal variations of daily means in 18C1 and 1802. Xll INTEODUOTION. A«^ Of the resulting values of ""^ and a^, those and those only were regarded as disturbances which equalled or exceeded the limits determined on for these elements, namely, .0004 for the total force, and r.O for the inclination. REMARKS ON THE TABLES. Tables I. to X. exhibit the aggregate values of the disturbances of the several magnetical elements, together with their constituents of opposite signs, distributed into the different years of their occurrence, as well as the ratios which the annual sums respectively bear to the average of the annual sums in the seven ye-ars lerminiiting December 31, 1862, for Tables I. III. V. VII. IX. ; and for the seven years terminuting June 30, 1862, for the remaining tables. At the foot of each table are given the ratios expressin!,' for cacli year, and for the 8even years collectively, the relative amount of disturbance of opposite signs. The results are given lor the yeaib ending .June 30 as well as for the ordinary years, for the sake of including tlie year ending June; 30, 1851, and also for the purpose of comparison with the earlier results at Toronto, and with the results at other stations where the years have been so divided. The year ending .June 30, 1856, includes, for the declination, an approximation to the amount of disturb- ance in July, 1855, calculated on the assumption that it would bear to the amount in the concluding months of that year, the same ratio as that furnished by the whole scries — 1856 to 1862. Approxi- mate values of the disturbances of the vertical force for July, and of the horizontal force, total force, and inclination, botli lor .Inly and August, 1855, have been similarly found and employed in calcula- ting the aggregates of disturbance for the year ending June 30, 1856. The ratios shewing the relative amount of disturbance of opposite signs in the seven years ending June 30, 1862, are, excepting for the declination, in every ca.se less than those furnished by the same six observation hours in the live years ending Jime 30, 18 18. Thus referring to the tables in vol. iii. of the " Toronto Observations," for the ratios that relate to the earlier series, and to tin; tables of this volume for the ratios belonging to the later series, we find as follows : i Easterly Declination < to f Westerly » Decreasing Hor.

IKTBOpiTCXIQN. • • • Table XI. has been drawn. up for tlie purpose of comparing the amount of disturbance of each kind 'u the five years from 1844 to 1848, with those of the later series. The years in every case ter- r:\) with June 30, and the numbers are those furnished by the observations made at the same six ho, ., In Table XII., the numbers in Table XI. have been expressed in terms of the average of the seven yearly sums for th^ seven years terminating June 30, 1862. These units of reference are em- ployed to shew better the periodic character of the last seven years ; and tliough not adapted to exhibit so distinctly the position of the several years, 1844-1848, in the decennial period in which these years are included, they render sufficiently apparent the relative magnitude of the annual aggre- gates in the two series. On examining Tables XI. and XII. it will be seen that 1856 and 1857 were years of minimum disturbance, and 1860 a year of maximum disturbance. The year 1859 shews a breach of continuily; its disturbances, excepting those of the declination, amounting to less than those of 1858 and 1860. If the years ending December 31 be compared, 1859 becomes the maximum yi-ar, chiefly on account of the extraordinary disturbance that accompanied the celebrated auroral display in September, 1859 ; but in this case, the disturbances of 1861 were, in several instances, slightly less than in 1860 and 1862. One striking peculiarity in these tables consists in the extraordinary amount of disturbance of all the elements in the year ending June 30, 1854. The observations during that year were taken under rather unfavourable circumstances. Portions of the building were in course of reconstruction, and workmen, with iron tools, were much about the premises ; but as it is believed that groat care was always taken to ascertain that no iron was left in dangerous proximity to the instruments during the observations, the anomalous character of the results cannot be tims wliolly explained. It will be seen Xhdi of the tlircc instrumentally independent elements, the vertical force was most afl'ected, — the amount of disturbance in this year so near to that of the expected minimum being actually in excess of that of 1848, the e|)och of maximum disturbance. Tables XIII. to XXVII. contain tlie aggregate values of the disturbances of the magnetical ele- ments, together with those of their constituents of opposite signs, distributed into the several months of their occurrence. The final column on the right contains the ratios that the twelve numbers in the preceding column respectively bear to the average of the said twelve numbers. The observations employed in the computation of the ratios are limited to those of the seven years 1856 to 1862 in- clusive. For the purpose of approximate comparison, in i'able XXVIII. the ratios corresponding to the preceding, and derived from the series from July 1, 1843, to June 30, 1848, as given in the third volume of the " Toronto Observations," have been placed in juxta-position with the ratios of the later series. The ratios are not strictly comparable on account of the fact that the later series embraces only the disturbances of six hours each day, whereas the earlier series includes those at each of the twenty-four hours. This circumstance will partly explain the following observed points of difference in the two series : (1) The maxima and the minima, in the move recent series, are less distinctly developed than in the earlier series. (2) In five instances the September maximum is transferred to October. ziT INTEODrCTION. (3) In nearly every case the April maximum occurs in March, and in the general disturbance of declination, as well as in those of westerly disturbance, the ratio is less than unity. (4) In every case there is an abrupt decrease in the November disturbances, with a subsequent increase in December. The generality of these points of din'ercnce, as far as they extend, will be better seen by com- paring the means of the ratios, for the declination, horizontal force and vertical force, as given in the following table : 3 C! t 1 •c >> o.

The ratios in the fuial coinnm are the values of the six hourly sums in the preceding column, expressed in terms of the average of the said six sums. Tiilile XXXIV. gives a c()mi)arative view of the diurnal distribution of the disturbances in the five years ending .lunc. 1848, and in the seven years ending Deeember, 18C2. The ratios for the earlier seri(>s arc not identical with those in vol. iii., but an; obtained by expressing the sums of the disturbances at the six observation hours in terms of the average of those six sums, instead of the avernijc of the twcnty-foiir hourly sums, as in the volume referred to. On eomparitig the two series, the chief clinnictcristic in the later sciies would appear to be that the distinctive features of ditferent parts of tlsc day, as shown in the earlier series, arc somewhat soft- ened down ; t!ie ratios that are above unity being for the most part less, and those that are less than unity l)eing greater in the later than in the earlier series In one ease only, namely, in the distur- bances tliat increast! tiie horizontal force at 8 a.m., do the ratios lie on opposite sides )f vmity in the two series ; but on reference to Tabh- VIII. of Vol. III., it is found that th? ratios at 9 a.m. and 10 a.m. are 0.94 and 1.46, so that the discrepancy amounts only to a transfer of the passage through unity from about 9 am. to 8 a.m. Tables XXXVl. to XL. give the solar diurnal variation of the several magnetieal elements at the six observation hours for each sepsirate month in which the instruments were in operation. The means arc in each case limited to the seven years ending December 31, 1862. Tables XLI. to XLV. contain for each of the seven years the annual and semi-annual means, and .semi-annual inequalities of the diurnal variation computed from Tables XXXVI. to XL. The num- bers in the table of semi-annual inequalities are obtained by subtracting the numbers in tlie tables of annual uican diurnal variation from the corresponding numbers when the sun was north of the equator; the signs of the inequalities, therefore, correspond to the six months from April to September inclusive. I INTRODUCTION. XV Table XLVI. furnishes at one view, and on the average of seven years, the solar diurnal varia- tions of the several magnetical elements at the six observation hours for each month, as well as for the year and for the winter and summer half-years, — the former extending from October to March inclu- Bive, and the latter from April to r«eptember. Table XLVII. exhibits a comparative view of the annual and semi-annual mean diurnal varia tion and semi-annual inequality, as furnished by the average of the five years ending June 30, 1848, and by the average of the seven years ending June 30, 1862. The comparison exhibits a close resem- blance in form, accompanied in most instances by an increase in the numerical values of the varia- tions, vhich is strikingly conspicuous in the case of the horizontal force. It will be seen from the mode in which the foregoing tables on the solar diurnal variaiion have been obtained, that the independent testimony that they supply relates only to the difference between the diurnal variations at the several hours, and th.tt the absolute values of the variations are afi'ected by constants, themselves derived from the older series, but which of course disappear from the ampli- tudes of the diurnal ranges. From the following table, containing an approximation to these amplitudes, it may be noticed that the prosrossion from year to year is substantially the same as that of the yearly aggregates of the disturbances, as shewn by Tables I. III. V. VII. and IX. ; and that in every case but in that of the declination, the increase in the aggregate disturbance of 18G2 above that of 1861, is accompanied by an increase in the amplitude of the diurnal range.

At the foot of each column, in every case wherein t'le requisite data could be procured, are placed the absolute values of the magnetic elements reduced to the normal mean of twenty-four hours. By applying to these absolute values the abnormal variations of the daily means of the respective elements, the absolute mean values of those elements on each day can be obtained, provided that it be assumed that the six-hour mean of each day diflers from the six-hour monthly normal by the same xH INTROfitrbTION. amount as the twenty-four-hour mean of the same day would differ from the normal derived from the twenty-four hourly normals. Thus if * be the absolute declination reduced to the normal mean of twenty-four hours, the mean absolute declination *,, on any given day in which the abnormal variation ia A*, will be given by the formula *, = * + A* ; Similarly, if X, Y, , be the absolute values of the horizontal force, vertical force, total force, and inclination, reduced to the normal mean of twenty-four hours ; X,, Y,, <^,, 0^ the required corres- A Y A Y A rA ponding values on the days in which the abnormal variations were respectively -^, -y-, -~, ^0; we shall then have * Y. = yJi+-^J; e^ = 6 -^ HkO. Tables XLIX. L. and LI. give a detailed statement of the dates and values of certain disturbed observations of declination, total force, and inclination, selected on account of their magnitude from the whole body of the disturbances of these elements. The limits employed for the selection are 15' for the declination, .001 for the total force, and 3' for the inclination. The relative number and relative aggregate value of these extraordinary disturbances in different years, as compared with the numbers and aggregate values of all the disturbances, are expressed by the ratios in tlie two subjoined tables.

In Table Ml. are given iIk? mean absolute declinations of each month during the years 1856 to 1862, and occasionally during the years 1853, 1854, and 1855. The mean monthly declinations contained in the tai)le, in almost every instance, are the means of six separate determinations made at int(!rvals during two or three consecutive days. Each determination includes five readings of tlie collimator seide, accompanied ljy simultaneous readings of the small declinometer, by aid of which the partial deterniii;ati(m was reduced to the twenty-four-hour mean normal reading for the month of liic small (h.'ciiiiouieler. 'I'lie lal)le embraces eerlaiii months for which the declinations have been already publishi-d in the third volume of the " Toronto Ohservations," and from which the declinations given in this table dill'er to a small extent, in eonsetpience of the declinations in vol. iii. having been reduced to the general mean of the month, including the dislurhcd as well as the undialurbcd readings of the small declinometer. The declination for January, 1854, has been omitted, on account of the great disconlancc of the partial results. The mean monthly increase of westerly declination, derived by the method of least squares from eighty-four eijuations, furnished by the monthly declinations of the seven years, 1856 to 1862, is 0'.27 16 ; which, if the rate of westerly movement be considered to increase e(|uably, will be the monthly rate corrcs|K)nding to July 1, 1859. But it has been elsewhere found that the monthly in- crease proper to July 1, 1848, is 0.1627: whence the mean annual increase in the mean monthly westerly movement will be —^ — = 0'.0102 nearly. The probal)le error of a single monthly determination is 0' .719, and the probable error of the mean determination 2'' 7 '.05, corresponding to July 1, 1859, is 0'.077. Table LIII. contains the monthly determinations of the dip, taken according to the method of which the details are given in the preceding volumes of the " Toronto Observations." The observa- tions were commonly made on three consecutive days, as nearly as possible about the middle of the month. One determination was usually made each day, between noon and 1 p.m. ; but prior to August, 1858, another determination was also made between 11 a.m. and noon. The values of the xvm INTllODCCTION. dip given in the tabic arc those derived directly from tiic observations, being uncorrected for diurnal variation. Tlie annual means exhibit u very distinct progressive change with o maximum of inclination in 1859. The annual variation of dip derived from the nine years, 1851 to 18C2, is not so distinctly de- veloped as in the scries 1811 to 1855. By combining two and two, the mean inclination of the six pairs of months, situated at ccpial distances from the middle of the year, wc find as follows : January and December — Mean inclination = 75° 23'.77 ") February " November " " 2 l.OO )■ 75* 24'.05.

Whence the inclination in January and December exceeds that of June and July by 0'.2G And the inclination in the winter half-year exceeds that nf tiie summer half-year by 0.82 In the earlier series the corresponding numbers are 1.71 and 097. Table lAV. gives the absolute values of the horizon! il force for each month, from Septemlier, 1855, to Decemlxr, 18(j2. Tiie observations tiiat siip|)ly the materials for computation were made wiili a very excellent vibration and deileclion apparatus, by Jones, of Uupert-slreet. Th< magnet in use from September, 1855, to November, 185(i, having iiecn liroken by a fall, it was replaced by another, which was employed to the end of the series. For the first magnet, the values of the constants 1* and Q in the expression sill u Tj, X ^+,^ + .^ derived by tln' method of least scjuares from 102 dedections, were P = —0.010831 Q = -h 0.001035 For ilie second magnet, the values of these constants obtained from 90 dcllections, were P = —0.018303 Q = +0.009329 The induction coefficient (/i) of the magnet in use subsequent to Nov<^mber, !85G, was detc^r- mined by an apparatus constructed at Toronto, on the principle of that employed by the late Mr. Welsh, of Kew. Its value was /i = 000120. In consecjucnee of the breakage of the first magnet before the experiments for induction were entered on, the determinations made with that magnet were approximately corrected for induction by the employment of the above-named value of fi. The determinations since July, 1858, were made from the observations during two days in each month, two sets of vibrations and detlections at two distances being taken each day. Prior to that lime the observations occupied three tlays, and the delleclions were made ea(;h day at three distances. In reducing the observations, the value of log ^ deduced from each separate deflection were combined with the mean value of log »nX derived from the two sets of vibrations taken in the same day. INTRODUCTION. xix The partial dclcrrninations of the hori/ontiil force being rcdiucd to tiic mcnn bifiliir reading of the day, by llio aid of Himnltanuous corresponding readings, they were afterwards redieed to tlie normal mean of the monlii by the application (with a contrary sign) of the aimormal variations of the means of horizontal force of the days on which the determinations were made. The values of the horizontal force given in Tublc LIV. arc the monthly means of the partial values reduced in tiie manner just described. The annual means at the foot of the table indicate that the decrease of the horizontal force jjrc- viously apparent, was arrested about the years 1859 and I8G0, — liie epo-.-h of maximum inclination, as shewn by Table LIII. The mean monthly values of the total force (<^), deduced from the formula <^ = X sec. 0, by the substitution of the corresponding values of the inclination {(*) and of the horizontal force (X), supplied by Tables LIII. and LIV. are given in Table LV. From this table it appears that the change of total force; has been for tiie most part a decrease', and by comparing tiie annual mciins with those on page xcii. of the second voluuie of the " Toronto Observations," it would seem that the change in tlu; total force underwent a change of sign between the years 1 818 and I85U. The supposition tliat the total force has been generally decreasing during the years 1850 to I8(i2, is supported by the indication of the Vertical Force Magnelomeley, If in lie the magnetic moment of the vertical force magnet, T llie lime of its vibration in the horizontal plane, \ and y ihc horizontal and vertical components of the force ; we have /;j\ = , , Sm AX ^ AT ""^•-«r + -X =-2"T (») where (AT) is the observed change in the time of vibration occasioned by a change (Ahi) of the mag- neti AX . ^ AY <{> X 1 = .0009:29 But tiie menu vulut- of tiic total (brce derived iVoiii Table LV. is derived from X and by the formula = X sec 6, are necessarily affected by the errors in the determination of X and tf, exaggerated by large multipliers, which in (f, are sufficient to mask its smaller changes, and render futile any attempt by more exact methcxls than those here employed to evolve their numerical values with precision. To determine the extreme and mean values of the total force in the secular period, with its epochs of maximum and minimum, a longer series of observationsis demanded, and the employment of methods independent of those made use of in determining the absolute values of the inclination and horizontal force.
