Print showing a range of compasses and proportional compasses. Signed T. Jefferys sculp. From a page of an Encylopaedia, probably from the late C18 or early C19.[^Since the drawings show the short "s" form in "compasses" (rather than "compaſſes") this might suggest that it was printed during or after 1795-1810 when the transition was firmly under way in printing in the US and England from the older long form of "ſ" to the modern "s" form.  In the US this transition was finalised by an Act of Congress in 1803. The still archaic shape of the "s" rendered - a little like the modern italicised //s// - still suggests the page was printed at an early point in the transition. Further complicating matters, Thomas Jeffries in his own advertisements from as early as 1760 scribes his name and associated words with a modern "s" so the plate may in fact reproduce the title that he printed on it with his careful engraver's hand, and be contemporaneous with his life.^]

An article in [[MapForum.com]] notes that Laurence Worms has contributed the entry on Jefferys to the forthcoming edition of the //Dictionary of National Biography// and believes that Jefferys was born in 1719, the son of Henry Jefferys, Cutler, of St. James Clerkenwell, although his place of birth is uncertain.  Worms has also located his apprenticeship, in December 1735, to the engraver and mapmaker Emanuel Bowen.  Jefferys was freed from his apprenticeship in 1744.  More reliably, Jefferys engraved some maps for Richard Pococke’s A Description Of The East, And Some Other Countries ... (London: 1743-1745), including map of Cyprus in volume 2. In 1746, Jefferys was appointed Geographer to Frederick, Prince of Wales, and in 1757, Geographer to George, Prince of Wales, later George III.[^Further information including the documentary basis for this description can be found at [[http://www.mapforum.com/15/jefferys.htm|Ephemera Thomas Jefferys Sr: Two engraved advertisement labels]] viewed 19 May 2012.^]
