Miscellanea Curiosa.

of the World: The one about sixteen Degrees therefrom, is in a Meridian, some twenty Degrees to the Westward of Magellan Straights , or ninety five Degrees West from London : This commands the Needle in all the South-America , in the Pacifick Sea , and the greatest part of the Ethiopick Ocean. The Fourth and last Pole seems to have the greatest Power, and largest Dominions of all, as it is the most remote from the Pole of the World, being little less than 20 Degrees distant therefrom in the Meridian, which passes through Hollandia Nova , and the Island Celebes about one hundred and twenty Degrees East from London ; this Pole is predominant in the South part of Africa , in Arabia and the Red Sea , in Persia , India , and its Islands, and all over the Indian Sea , from the Cape of Good-Hope Eastwards to the middle of the great South Sea, that divides Asia from America . This seems to be the present Disposition of the Magnetical Vertue throughout the whole Globe of the Earth; it remains to shew how this Hypothesis makes out all the Variations that have been observ'd of late; and how it answers to our several Remarks drawn from the Table. And first it is plain, that (our European North Pole being in the Meridian of the Lands-end of England ) all places more Easterly than that will have it on the West side of their Meridian, and consequently the Needle, respecting it with its Northern Point, will have a Westerly Variation, which will still be greater as you go to the Eastwards, till you come to some Meridian of Russia , where 'twill be greatest, and from thence decrease again. Thus at Brest the Variation is but 1¾ Degrees, at London 4½ Degrees; but at Dantzick seven Degrees West. To the Westward of the Meridian of the Lands-end, the Needle ought to have an Easterly Variation; were it not that (by approaching the American Northern Pole , which
