• Horometria: or The compleat diallist Wherein the whole mystery of the art of dialling is plainly taught three several wayes; two of which are performed geometrically by rule and compass onely: and the third instrumentally, by a quadrant fitted for that purpose. With the working of such propositions of the sphere, as are most usefull in astronomy and navigation ... By Thomas Stirrup, philomath. Whereunto is added an appendix, shewing how the parallels of declination; the Jewish, Babylonish, & Italian houres; the azimuths, almicanters, &c. may be easily inscribed on any dial whatsoever, by rule and compasse onely. And to draw a diall on the seeling of a room, by W. Leybourn. Also, Dialling Vniversal, performed by an easie and most speedy way, ... by certain scales set on a small portable ruler, by G.S. practitioner in the mathematicks

• The sector on a quadrant, or, A treatise containing the description and use of three several quadrants each rendred many wayes both general and particular. Accommodated for dyalling, for the resolving of all proportions instrumentally, and for the ready finding the hour and azimuth universally, in the equal limb. Of great use to seamen, and practitioners in the mathematiques. Written by John Collins accountant, and student in the mathematiques. Also an appendix touching reflected dyalling, from a glass however posited. With large cuts of each quadrant, printed from the original plates graved by Henry Sutton, either loose, or pasted upon boards

• 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.

• 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
