Descr.New Instrument invented by John Hadley for taking the Latitude or other Altitudes at Sea... 32pp. folding engraved frontispiece signature of Charles Vallancey at head of title and numerous ink annotations ?in his hand a little soiled later calf-backed cloth 8vo by E.Say 1748. ***John Hadley (1682-1744) was a mathematician and scientific mechanist. “In 1730 independently of Thomas Godfrey of Philadelphia Hadley invented a quadrant (actually a double-reflecting octant) for measuring the altitude of the Sun or a star above the horizon to find geographic position at sea. His double-reflecting principle made accurate determinations of location much easier. Hadley also fixed a spirit level to the instrument so that a meridian altitude at sea could be taken when the horizon was not visible. His device later evolved into the sextant.” Encyclopaedia Britannica Charles Vallancey (1721-1812) antiquary and scholar of Irish history and languages. He also translated French works on fortification and engineering..
