A telescopic observer's platform which revolves in any direction, permitting a person making observations to follow the instrument in its rotation, has been constructed for the Harvard Observatory, by the General Electric Company plant at West Lynn.
The machine was built at the suggestion of Dr. Shapley, director of the observatory, to be installed in the organization's station at Bloemfontein. South Africa.
Designed by John French, the equipment consists of a travelling carriage moving upon circular rails, supporting a tower, which in turn supports a gallery. The latter can be raised, lowered, or turned horizontally.
