(1) From formula on page 30.
(2) The solution factor of O’Sullivan (J. Chem. Soc., 1876, p. 129)
was employed with slight modification. The formula employed was
1000(_d_ - 1000) / 4.35 = per cent solids. In this formula
_d_ = specific gravity of solution at 20° C.
(3) From formula on page 31.
(4) For these figures the formula of footnote 2 was employed and the
