The officially recognized figure for the acceleration due to gravity is 9.806 65 m.s-2. Saint John, New Brunswick, is a few metres above sea level, otherwise it would be flooded by Bay of Fundy high tides. Its latitude is 45° 16' and my 1937 Handbook of Chemistry and Physics gives its acceleration due gravity as 9,806 63 m.s-2. Joseph B. Reid 17 Glebe Road West Toronto M5P 1C8 Tel. 416 486-6071
