The data relating to alcohol were obtained by Pictet,
and those for calcium chloride by Pickering. The latter are materially
different from figures given by other investigators, and perhaps it would
be safer to make due allowance for this difference. In Germany the
Acetylene Association advocates a 17 per cent. solution of calcium
chloride, to which Frank ascribes a specific gravity of 1.134, and a
freezing-point of -8 deg. C. or 17.6 deg. F.
