The determination of longitudes has from the beginning been environed with almost insuperable difficulties. At one period the declination of the magnetic needle was supposed to furnish the means of a practical solution. Sebastian Cabot devoted considerable attention to the subject, as did likewise Peter Plancius at a later date. Champlain appears to have fixed the longitudes on his smaller map by calculations based on the variation of the needle, guided by the principles laid down by Guillaume de Nautonier, Sieur de Castelfranc, to whose work he refers in the text. It was entitled, _Mecometrie de l'eymant c'est a dire la maniere de mesurer les longitudes par le moyen de l'eymant_. This rare volume is not to be found as far as my inquiries extend, in any of the incorporated libraries on this continent. There is however a copy in the Bodleian Library at Oxford, to which in the catalogue is given the bibliographical note: _Six livres. Folio. Tolose, 1603_.
