Recent investigations as to the value of the metric unit of volume —the cubic decimetre—appear to show, indirectly, that the present weight of a cubic inch of distilled water (252*458 grains, t = 62° F.» 5 = 30 in.)—the hitherto accepted unit of volume in this country—* is appreciably too high. This weight (252*458 grains) is based on weighings made by Shuckburgh in 1798, and on linear measurements by Kater in 1821; but their results are affected by uncertainty as to thermometric and linear measurements, and as to the condition of the water used. Hence a direct re-determination of the unit of volume in this country appeared now to be desirable
