⁂ Leybourn's first book on sundials. ESTC lists two issues, one with "dialling," in line 2 of title and the imprint date 1669 (ESTC R231068). The other has "dialling:" and is undated (ESTC R17714), of which ESTC records only one copy in the British Library. Some argue that the undated issue has priority as the first. This copy has "dialling," in line 2 of title but is undated, thus appearing to be a mixed issue.

Provenance: Christopher St. J.H. Daniel (sun-dial designer; ink-stamp to pastedown & front free endpaper); Kenney Collection (book-label).
