Abstract
To measure the altitude of a star when on an expedition, one uses a theodolite, a portable transit instrument, or a sextant (on a ship). We shall avail ourselves of the very simplest means: a rectangular board, fastened to a heavy stand, which we place in the proper orientation. The board turns around a screw and its long side is pointed to the star by means of the sights M and N, then the board is gently clamped in place by a winged nut.
