The making and decoration of dials. William Leybourn (1627-1716) was a well-respected mathematician, surveyor, and private tutor. First published in 1682, Dialling greatly enlarged upon the author's earlier treatment of the subject, The Art of Dialling (1669). It contains a long section on the making and decoration of dials, two chapters on reflex dialling (by John Twysden and Im. Halton), and an abbreviated version of Francis Hall's description (first published in 1673) of an elaborate sundial he set up at Whitehall. Both editions are scarce, but this is the more significant edition as has been corrected and enlarged to include new tractates.

Second, enlarged edition, small folio, 34 (of 35) engraved plates including frontispiece portrait, 14 folding and 4 engraved vignettes, paper flaw to one corner, old ink ownership markings to blank ff. at ends (tabbed in), contemporary calf, rebacked to style, upper joint repaired.
