OPERATION IX. To know how many hours any Star stays above or under the Horizon.

REctify the Bead to the Declension of the Lions Heart, and moving your String on the Noose from the Pole, till the said Bead touches the Horizon on the West side, see what Hour-Circle cuts with it there, and you will find it to be that of 7 and a quarter or thereabouts; and this doubled (making in all some 14 hours and a half) gives the true time of its stay above the Horizon; so 4 and three quarters doubled (I mean the Hour-Circle which Intersects with it on the East side) gives you 9 hours and a half for its stay below the Horizon.
