[Footnote 1: Data relating to the relative pecuniary values of acetylene
(carburetted or not), coal-gas, paraffin, and electricity as heating or
illuminating agents, are frequently presented to British readers after
simple recalculation into English equivalents of the figures which obtain
in France and Germany. Such a method of procedure is utterly incorrect,
as it ignores the higher prices of coal, coal-gas, and especially
petroleum products on the Continent of Europe, which arise partly from
geographical, but mainly from political causes.]
The mixture was tried also at higher pressures in the same burners, but
with less favourable results in regard to the duty realised.
