A supplement to geometrical dialling, / by William Leybourn, philomath. Shewing how by scale and compasses to inscribe such circles of the sphere into sun-dial-plains, that shall shew (besides the hour of the day) the diurnal motion of the Sun; his place in the zodiack; the time from his rising, and setting; the Babylonian, Italian, and Jewish hours; the point of the compass upon which the Sun is at any time of the day, and the proportions of shadows to their heights. Also a general and easie way to project hour-lines upon all kinds of superficies, without any regard had to their standing, either in respect of declination, reclination, or inclination. And how from a glass horizontally placed in the soyl of a window, to reflect hours upon any superficies, either flat, or curved; one, or many.
