Since the publication of Gravimetry in Australia 1819-1976 (Dooley and Barlow, 1976), our attention has been drawn to the paper by Day (1966) on early Australian geophysical history. We apologise for our ignorance of this interesting paper, which refers to many of the nineteenth-century gravity measurements listed in our Table I, and gives further details of the observers and the background to the measurements. In Table 1, we had compared the results of the older measurements with currently accepted values of gravity. For completeness, we analyse below a notable series of measurements at Parramatta between 1821 and 1828, which we omitted from our history.
