The central line passes near the northern coast of South America, across the Atlantic Ocean, to England and the northern part of Europe; it will not be visible in the United States west of a line passing from the western shore of Lake Superior to the city of Mobile. The beginning will not be visible in the United States excepting in the eastern part of Maine.

The following times have been obtained from a chart of this eclipse constructed by the Rev. Thomas Hill, employing the "Occultator" invented by him for the computation of eclipses and occultations. A rigorous computation for the time of ending at Washington differed by only twelve seconds from the time given by the "Occultator."
