Observations of the diurnal variation of the magnetic needle, in the Island of St. Helena; with a continuation of the observations at Fort Marlborough, in the Island of Sumatra","authors":"J. Macdonald","doi":"10.1098/rstl.1798.0019","DOIUrl":"https://doi.org/10.1098/rstl.1798.0019","url":null,"abstract":"Sir, On my arrival in England, I had the honour of observing to you, that I had taken some observations of the diurnal variation of the magnetic needle, in the island of St. Helena. I am to apologize to you for having, till this period, omitted furnishing you with these, and with a continuation of those formerly taken in the island of Sumatra. The meridian was laid off by means of an apparatus brought from Bencoolen; and the requisite allowance made for the alteration of the sun's declination during the operation. The meridian-plate remains firmly set in a pillar of teak-wood, well fixed, for the use of navigators; who, by applying a compass-card to it, will find the variation more readily, and correctly, than by amplitude or azimuth. A short residence at St. Helena, arising from the sudden departure of the fleet to which the ship I was in belonged, has prevented the observations from being as numerous as I could wish. Their agreement, however, indicates that fifty-eight observations are sufficient for affording such conclusions as philosophy may draw; and tends to confirm some inferences stated in a former Paper, containing similar observations taken in the East Indies. By adding the mean of the morning and afternoon observations, at St. Helena, and taking the half, the general variation, in the month of November, 1796, appears to have been 15° 48' 34\" 1/2 west: and, by subtracting the medium diurnal afternoon variation, from the medium diurnal morning, the vibrating variation proves to be 3' 55\". It appears, that the magnetic needle is stationary from about six o’clock in the evening till six o’clock in the morning; when it commences moving, and the west variation increases, till it amounts to its maximum, about eight o’clock; diminishing afterwards, till it becomes stationary. Here, the same cause seems to operate as at Bencoolen, with a modification of effect, proportioned to the relative situations of the southern magnetic poles, and the places of observation. At the apartments of the Royal Society, this species of variation is found to increase, from seven o’clock in the morning till two o’clock in the afternoon. If the variation is east, in the northern hemisphere in the East Indies, I conceive that the diurnal variation will increase towards the afternoon, remain some time stationary, and diminish before the succeeding morning: if the general variation is west, in that quarter, the reverse may be the case. The quantity of the diurnal variation is greater in Britain than at St. Helena, or at Bencoolen. This will naturally arise from this country’s being more contiguous to its affecting poles, than those islands situated near the equator. It were to be wished, that observations were taken in as many situations as possible, similarly situated in the opposite hemispheres, on the lines of no variation. A greater degree of dip might be found, and conclusions might be deduced, that would tend considerably to illustrate this curious and interesti","PeriodicalId":20034,"journal":{"name":"Philosophical Transactions of the Royal Society of London","volume":"91 1","pages":"397 - 402"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79436454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
