 INTRODUCTION, 
 
 Hourly Magnetical and Meteorological Observations were first ordered at Madras by the 
 Honorable Bast India Company upon the recommendation of the Royal Society, and were commenced in 
 March 1841, under the direction of the late Major General (then Captain) S. 0. E. Ludlow. 
 
 The original Magnetical Observatory was located in the grounds of the Old College, about a 
 quarter of a mile eastward of the Astronomical Observatory and the instruments were recorded there until 
 1847 October 27th, when they were removed to the latter establishment and handed over to the future 
 management of the Astronomer, Mr. T. G. Taylor. All the Magnetical registers and their partial reductions 
 for the first five years, 1841 to 1845, were taken by Captain Ludlow to England, with a view to their being 
 completed and published by him. This however was never accomplished. The papers were lost sight of 
 for many years, but were ultimately returned to the care of the head native assistant, R. Ramanajooloo 
 Naidoo, who. had made by far the largest share of the observations and probably all the calculations of the 
 partial results. Ramanajooloo completed the reductions for the early years privately, and before retiring 
 on pension at the end of 1871, handed the in over to the Government Astronomer, to whom they should 
 have been sent when returned, instead of to one of his assistants. The papers appear to have been 
 prepared with all the accuracy and neatness which distinguished Ramanajooloo' s work in general, but 
 Avill of course require careful revision before they can be considered ready for publication. Ramanajooloo 
 was a rare instance of. a native who delighted in his scientific occupation more for its own sake, than for 
 the moderate pay it procured him, and who, at a time when higher education was not so easily attainable 
 as it now is, managed to acquire a fair knowledge of mathematics, so far as spherical trigonometry, and 
 an intelligent comprehension of all the processes, alike of observation and calculation, required in the 
 discharge of his somewhat difficult duties. He died in 1880. 
 
 The Magnetical Observations for the next five years, 1846 to 1850, were made under the 
 successive superintendence of Mr. T. G. Taylor ; Captain W. K. "Worster, Madras Artillery, and Captain 
 W. S. Jacob, Bombay Engineers, all now deceased. The calculations and press revision were the work of 
 R. Ramanajooloo, and the results were published by Captain Jacob in 1854. 
 
 The printing of the third five years series, from 1851 to 1855, contained in the present volume,, 
 was commenced in July 1860, when no astronomical work was. in hand ; the old instruments being 
 dismounted and the new Transit Circle not yet ready for use. The results for 1851 were completed by 
 Ramanajooloo before my arrival in India, which will account for the somewhat remarkable foot notes to 
 be found in the earlier pages. The erection of the new Transit Circle and other instruments ; the far 
 more important astronomical arrangements then inaugurated and the frequent discoveries made during 
 the next five years, caused the less interesting arrears of Magnetic researches to be comparatively shelved; 
 and above all, the discouraging regulations in regard to the distribution of volumes, peculiar to Ma,dras 
 though unknown elsewhere, all combined to delay the completion of the volumes. The very kind and 
 liberal consideration of the present Government of Madras, in removing the painful restrictions hitherto in 
 force, will insure the earliest possible publication of all past results on hand, and will give renewed energy 
 to the future exertions of the oldest established English colonial observatory. 
 
 The forms adopted in the previous volume, for 1846 to 1850, have been strictly adhered to in the 
 following pages, though in many respects not in accordance with my own views upon the subject. The 
 English practice of leaving Nature's works unrecorded on Sundays and the adoption of Gottingen Mean 
 Time for the commencement of the day, together, caused only six hours observations to be made on each 
 Saturday, and after a break of twenty-four hours, thirteen more on Sunday (Madras Monday, A.M.). By 
 the application of proper hourly corrections, the deduced means for each day might easily have been 
 shewn'; instead of which the Saturday mean results are omitted, and those given as for each Sunday are 
 
IV 
 
 made up of observations, partly on Saturday but chiefly on Monday. With a questionable view to lighten 
 the labors. of the observers in some years, five of the hourly observations were omitted during the night ; 
 but here again, instead of using the means of the nineteen readings actually made, with the proper hourly 
 corrections duly applied, the missing hourly records were filled up by dubious interpolations. Days of 
 imperfect or broken records, usually attributable to sudden illness or ceremonies incumbent upon the 
 native observers, as for instance in the first week of 1851, were entirely omitted from the daily and 
 monthly means. The results of the Force Observations should have been reduced to British, or better 
 still to continental units, instead of being given as mere ratios ; and lastly, there is too frequently a very 
 needless display of decimals, far in excess of what the observations warranted; a weakness common 
 to many similar scientific labors, elsewhere as well as at Madras. 
 
 THE DECLINATION MAGNETOMER. 
 
 The steel bar magnet employed was fifteen inches long, seven-eighths broad and a quarter of an 
 inch thick. Its weight was 6713 grains, or when equipped with its scale, stirrup and lens, 8838 grains. It 
 was suspended between two copper dampers, by twenty-four silk fibres ; the distance between the 
 bar and its point of suspension being about thirty-six' inches. The Torsion Circle was four and a half 
 inches in diameter. Eeading telescopes and collimators were supplied with the magnetometers, but by 
 some oversight the latter were used instead of the former, which unfortunately gave rise to the possibility 
 of the vertical reading wire being changed, by the collimator being turned round one or more quadrants, 
 which of course never could have occurred had the proper reading telescopes been employed. A thirty 
 inch Transit Instrument, by Dollond, was used for finding the astronomical north, and an excellent eight 
 inch Everest's theodolite, by T. Jones of London, placed midway between the Transit instrument and the 
 Declinometer, gave the azimuth of the vertical wire of the reading telescope and hence the magnetic 
 declination at any time desired. Four substantial brick piers, each about eight feet apart, supported these 
 appliances nearly in a meridian line ; the Transit instrument being most northward and the reading telescope 
 of the Declinometer the southernmost of the four. All the Magnetometers bear the maker's name " Grubb, 
 Dublin." 
 
 
 
 The observations of the Declination Magnetometer are printed, as read off, in tenths of the scale 
 divisions ; the daily means only being shewn in arc. A correction cf + 7' 6" has been applied throughout, 
 for the influence of the brick walls of the building. The details of this determination were given in Tables 
 VI to XI of the' previous volume. The adopted value of one division of the scale was determined on 26th 
 April, 1847, viz., 40"'30; that furnished by the Royal Society in the " Report of the Committee of Physics" 
 page 23, being 40" : 48. The adopted Zero of the Declinometer Scale throughout the five years was 1497, 
 the mean of two determinations in March and December 1854. 
 
 INDUCTION INCLINOMETER. 
 
 No trace of this instrument remaining in the Observatory or in the recollection of any one now 
 on the establishment, all that can be said concerning it is, that its readings have only been retained on 
 Term Days and on the occasions of Disturbance Observations. The following brief description of it was 
 given by Captain W. S. Jacob in the " Introduction" to the former volume. 
 
 " The instrument used is a small portable unifilar Magnetometer, with a cylindrical needle, a 
 " quarter of an inch thick and three and a quarter inches in length, and two soft iron bars of three- 
 " quarter inch thickness and nine inches length. The instrument appears inapplicable to these latitudes ; 
 " its changes appear to follow those of the Declinometer very closely, so that no certain deduction can be 
 " derived from them." 
 
 HORIZONTAL FORCE MAGNETOMETER. 
 
 The instrument by which the hourly changes of the horizontal component of the earth's magnetic 
 force was measured, was a bifilar magnetometer, with a steel bar, suspended by two silver wires, or more 
 correctly, by a single wire a little over seventy-two inches in length, passing round a pulley 0'645 inch in 
 diameter. By means of a four and a half inch torsion circle above, the magnetic bar was turned to point 
 
nearly East and "West, in which position its equilibrium would be maintained by two opposing forces ; that 
 of the earth's directive power, tending to bring it to the magnetic meridian ; and that of gravity, which 
 would compel it to rest in the direction of the two supporting points of the wire by which it hangs. 
 The latter force is variable only by the slight alteration in the length of the wire, arising from a 
 change of temperature which can be duly allowed for, while the former is altered by every change in the 
 earth's directive magnetic force. At right angles to the magnetic bar, a small collimator is attached, the 
 axis of which will therefore be the magnetic meridian, and every change in its direction indicated by the 
 varied readings of its divided scale, as seen in a small fixed telescope, is readily convertible into correspond- 
 ing changes of the earth's horizontal magnetic force, by means of well known formulae, given in the Royal 
 Society's " Report of the Committee of Physics," which have been strictly followed throughout and 
 therefore need no repetition in this brief description of the instrument. 
 
 The records printed are, the hourly readings in tenths of the scale division on the upper half of 
 each page, and the corresponding temperatures on the lower half. Temperature corrections are shewn for 
 the mean daily readings and for the mean hourly readings for each month, and only these corrected means 
 
 A ^T 
 
 are reduced into the relative magnetic force changes represented by the expression 1 + -^- 
 
 The value of one division of the scale furnished by the Royal Society was 64'"74, or expresed 
 in parts of radius, 0'0003l,39. Owing to the scale having been inverted throughout, increase of force is shewn 
 by diminished readings of the instrument. The Fahrenheit's thermometer used read >0 5 too high, and 
 the adopted temperature correction was 3 - 3963 divisions for each degree. The value of the angle v, used 
 during the five years, was 75 15' as found on June 30th, 1851 ; and the Zero of the scale, reduced to the 
 standard temperature of 80, was 1215. 
 
 Throughout the year 1846, and also in 1847 until October 19th, when the instruments were 
 removed to the Astronomical Observatory, the angle v was always erroneously given 90 two great, at 
 the top of each page in the former volume, but the correct value was fortunately used in the 
 calculation of k. 
 
 VERTICAL FORCE MAGNETOMETER. 
 
 The Vertical Force Needle was of the. ordinary construction and 13'5 inches in length. The 
 Vertical Force results were never entitled to any confidence, especially before March 1st, 1853, when, for 
 the first time, the needle was placed nearly perpendicular to the magnetic, meridian, agreeably to the 
 directions so clearly given in the Royal Society's " Report," page 32. Previously to that date it had been 
 curiously misplaced, 45' West of the magnetical meridian, instead of at right angles thereto. 
 
 The elements of reduction being given in full at the top of each page of the observations, it is 
 needless to repeat them in a tabular form here. As stated at the foot of page 20, increasing readings 
 shew a diminution of force. They are given in tenths of the micrometer divisions, and the temperatures of 
 the thermometer inside also to tenths of a degree Fahrenheit, the daily mean temperatures being most 
 needlessly extended to hundredths of a. degree. Only monthly results of ^- are shewn, for the purpose 
 of giving the hourly variations from the monthly means. 
 
 DISTURBANCES OF THE MAGNETIC OBSERVATIONS. 
 
 Whenever any decided departure from the usual hourly variations of the instruments was noticed, 
 readings of all four magnetometers were recorded at brief intervals of five minutes or less. These observa- 
 tions are separately given on pages 221 to 231. 
 
 MAGNETIC INCLINATION OR DIP. 
 
 The Dip Circle, ten inches in diameter, by Robinson, of London, was the same used by Captain 
 Ludlow in the old Magnetic Observatory ; a smaller circle, by the same maker, having been employed from 
 1846 to 1850. The observations were made on Tuesdays and Fridays, at 6^ and 11| A.&., near the times 
 of presumed maximum and minimum inclination at Madras. They were carefully taken and are entitled 
 to consideration, though certainly not reliable to seconds of arc, as given in the printed results. 
 
YI 
 
 ABSOLUTE HORIZONTAL FORCE. 
 
 Determinations of the Absolute Horizontal Intensity were usually made near the end of each 
 month, with an independent Declinometer, similar to the one before described, but placed in a detached 
 building expressly for that purpose. The absurd detail of these observations and their reductions in the 
 former volume was beyond endurance, and the printed results in this volume have been considerably 
 abridged, though still carried out to a most unwarrantable extent of mere arithmetical display. 
 
 The magnet was of the same dimensions as that used in the other Declinometer. Its weight was 
 stated to be 6727 grains up to 1854, July 27th; and g at Madras, 32'0984 feet. Hence log. Ic was 1-43745. 
 The magnet was cleaned before the next observation in 1854, September 1st, and was then found to weigh 
 only 6695 grains, which changed log. le to 1-43538. 
 
 The value of one division of the scale was 40"30. 
 
 . The Torsion Factors 1 + -^ employed were not shown in the calculations, but were mixed up with 
 the scale value. Separating them therefrom, the following are the factors really used : 
 
 1851January28 1-00023 
 
 1851 November 27 1-00030 
 
 1854 September 25 ... 1-00035 
 
 1851 October 26 1-00041 
 
 1854 December 3 ...' ... 1-00053 
 
 1855 December 24 1-00037 
 
 "With the aid of these constants, the observations and. partial results printed on pages 234 to 
 238, can readily be converted into absolute determinations of X ; which, hewever, simply expresses the 
 ratio which that force bears to the unit of force. In the former volume this was only given as a ratio, 
 and required to be multiplied by V g to express it in British Units. 
 
 In the present volume, British Units (foot, grain, second) are used, though I have feeen strongly 
 urged to adopt the continental units (centimetre, gramme, second) by two eminent magnetists to whose 
 opinion I shall probably defer in the two remaining volumes. One of these, the still unpublished first, 
 will contain the observations from 1841 to 1845; the fourth and last of the twenty year hourly series 
 carried out at Madras, will be for the years 1856 to 1860. 
 
 The remaining tables, after page 239, require no remarks beyond my dissent from their needless 
 detail. With rare exceptions, all the records and determinations were made by the native assistants, 
 whose names and adopted initials, in this and the former volume, were as follows :

 Of the successive Directors of the Magnetical Observations, viz., Colonel S. 0. E. Ludlow, Mad. 
 Eng. ; T. G. Taylor, Esq., H. C. Astronomer; J. J. Franklin, Esq., Superintendent of Marine; Captain 
 W. S. Jacob, Bom. Eng. ; Major General W. K. "Worster, Mad. Art., and Major General J. F. Tennant, B. E., 
 who was in charge in 1860, only the last survives. The six first native assistants in the list are all dead, 
 and the last three, though still living, are incapacitated and oblivious of the past. The difficulty of publish- 
 ing arrears of scientific observations, when not one concerned in them can be consulted, is very serious, 
 and must be accepted as an apology for all shortcomings in the present volume.
