Lot Essay

Francis Hauksbee (1687-1763), scientist and lecturer who made among other instruments 'several sorts of barometers'. A similar barometer is illustrated in N. Goodison, English Barometers 1680-1860, Woodbridge, 1977, p.p. 162-163, pls. 100, 101. The illustrated barometer from Althopp has special finger grips for the indicators on the dials but is without the themometer, a feature included in another barometer refered to by Goodison.
