Abstract
THE YERKES OBSERVATORY.—From a note in the Astrophysical Journal for June, we learn that the construction of the buildings of the Yerkes Observatory is advancing rapidly, and it is hoped the 4O-inch refractor will be ready for use in September or October. The Observatory is situated on the shores of Lake Geneva, Wisconsin, at an elevation of 180 feet above the lake, and is about seventy-five miles from Chicago. The dome for the great telescope, which is being built by Warner and Swasey, is 90 feet in diameter, with a shutter opening 12 feet; the rising floor is 75 feet in diameter, and will have a vertical movement of 22 feet. The motive power for turning the dome and elevating the floor of the Observatory will be supplied by electro-motors.
