...motion within, so that neither the variation nor the dip would always remain the same at the same spot. The existence of more than one magnetic pole in either hemisphere has been rendered highly probable; and it seems to be decided that there is one in Siberia. In some places the dipping needle is horizontal,... | |

Lyon, on an expedition for the same purpose, found that the magnetic pole was then situate in 63° 26' 51" north latitude, and in 80° 51' 25" west longitude. It appears, from later researches, that the law of terrestrial magnetism is of considerable...
