Perpetual motion. --The Watertown Jeffersonian says that Mr. Robert Hitchcock, of that place, has invented a clock that never requires winding up by hand, and will keep running until it is worn out, if left alone.--After being put up it requires no further attention. It also acts as a ventilator. The invention is designed especially for town clocks and large office clocks, to any of which it can be applied. Mr. Hitchcock has received a patent.
