Summary:
J. H. Lefroy returned from McKenzie River [Canada] having established at least 350 magnetic stations between there and Red River, 'a fine pendant for [J. C.] Ross's survey' in southern hemisphere.' If expedition continues through winter, it will provide excellent survey of North American disturbances.
