Abstract
FROM January until July of the present year, a series of radio observations on the ionosphere has been undertaken at McGill University in connexion with the International Polar Year. The normal height of the E layer is rarely found to be below 100 km., regular measurements on 2.0 and 4.0 megahertz giving a modal value of 120 km. The modal value for F on the same frequencies is 260 km.
