• 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

• The art of dialling performed geometrically, by scale and compasses, Two several ways. Arithmetically, by the canons of signs and tangents: instrumentally, by a trigonal instrument, accommodated with lines for that purpose: the geometrical part whereof is performed by projecting of the sphere in plano, upon the plain it self, whereby not only the making, but the reason also of dials is discover'd. The third edition, enlarged. With a supplement, shewing how geometrically and mechanically to insert into all sorts of sun-dials, such circles of the Sun's course as gives the hour and length of the day, according to the account of several countries, &c. And to project and reflect hour-lines upon all sorts of superficies, plain or curved, without any regard had to their standing, either in respect of declination, or inclination.

• The art of dialling by a new, easie, and most speedy way. Shewing, how to describe the hour lines upon all sorts of plains; howsoever, or in what latitude soever, situated. Also; to find the hour of the day, and the azimuth of the sun, whereby the sight of any plain is examined. Performed by a quadrant filled with lines necessary to that purpose. Invented and published in anno 1638. by Samuel Foster, then professor of astronomie in Gresham Colledge. The second edition, with several additions and variations of the authors, deduced from his own manuscript. With a supplement, performing all the instrumental work of the quadrant, by calculation. By help of the canons of sines and tangents, which of all ways is the most exact. By William Leybourn philomath
