New Equipment for Observatory

The sixty-inch reflector which is now being mounted at the Observatory, will when completed, be one of the three largest and most powerful in existence. It will be used for extremely delicate work on faint stars and nebulae, and will be under the complete electrical control of one operator. The reflector, which is of tremendous weight, will rest on a fluid to make manipulation easier.

A powerful two-foot reflector is also being mounted, to be used principally in photographing an interesting class of stars known as the Algol-variables.

During the summer several hundred variable stars have been discovered at the Observatory and two comets announced.
