The table below gives the correction to be applied to A. D is taken as -9992 (correct to 1 part in 2000 between io° and 180 C., see p. 22) and <r as -0012 (see p. 25). — means that the correction has to be subtracted from A.

(see p. 25), H is the barometric height, and / is the pressure of water-vapour in the air. HYDROMETERS Common: Density = degrees/1000. Baume : Density at 15°= 144-3/(144-3 — Baume degrees). Twaddell: Density = 1 + (Twaddell degrees/200). Sikes : One degree = a density interval of *002 on the average.
