Abstract
THE TOTAL SOLAR ECLIPSE OF SEPTEMBER 10.—This eclipse is total in south-west California and the adjacent islands; also in Mexico. There is no official expedition from the British Isles, but many of the great American Observatories are sending parties to observe it. Popular Astronomy for June-July contains an outline of their programmes. The Yerkes, Washburn, and Goodsell Observatories are occupying Catalina Island. The Washburn party will measure the brightness of the corona by the photo-electric cell; the Goodsell party will photograph the corona and star-field with an 8-inch lens, and the flash spectrum with a grating.
