Greenwich and Washington have telescopes with apertures of twenty-six-inches. The largest instrument in the possession of the Harvard Observatory is the twenty four inch Bruce photographic telescope, mounted at Arequipa...

By the use of a switch board one man can operate from this station as many of the instruments as he may desire. In order that the motion of the earth may not effect the relative position of the photographic telescope and the object, the instrument is moved on an axis parallel to the earth and regulated by clock work in such a way that the distance the earth moves...
There are two other stationary instruments. Over the end of one a prism is placed, which breaks up the light of the stars so that by the study of the rays the composition and character of any one star may be accurately determined. The second instrument is regulated by two ordinary alarm clocks, which open and close the shutter at any time the operator may wish. Every night this telescope is pointed directly at the north star, and after an exposure of twelve hours a semi-circle is thus traced on the plate. By this device an impression...
