The Ancient Copper Mines Of Isle Royale, N. H. Winchell Dec 1880

The Ancient Copper Mines Of Isle Royale, N. H. Winchell

Journal of the Minnesota Academy of Science

Two papers were read in 1880, by Prof. Winchell, on the ancient copper mines of Isle Royale. After an account of the exterior phenomena of the mines, and an enumeration of the articles found in them, an inquiry was instituted as to the race that wrought them, and as to their relation to the Mound Builders, and to the Indians. As it has been admitted for several years that the Lake Superior miners were identical with the Mound Builders, the inquiry involved the examination of the relation of the Mound Builder to the present Indian. The characteristics of the Mound …

You are all familiar with the westward march of cholera among men and epizooty among animals. In surgical operations the danger is not from the operation, but from germs which are in the air and which get into the body through the wound, producing surgical fever, etc. Since Lester used the carbolic acid spray …

The Fixed Stars, John F. Downey Dec 1880

The Fixed Stars, John F. Downey

Journal of the Minnesota Academy of Science

The object of this paper is to give, in a popular form, a brief review of what is known about the fixed stars. Although they have always been objects of interest, have guided the mariner over trackless seas, arid have inspired many sublime and noble thoughts, yet, until a comparatively recent date, only three things were known about them; viz., that they retain (approximately) their ·relative positions, that they are self luminous, and that they are very far away.
