Moreover, the
odour of the acetylene itself would render the detection of a leak far
easier with carburetted acetylene than with air-gas.
N. Teclu has investigated the explosive limits of mixtures of air with
certain combustible gases somewhat in the same manner as Eitner, viz.: by
firing the mixture in an eudiometer tube by means of an electric spark.
He worked, however, with the mixture dry instead of saturated with
aqueous vapour, which doubtless helps to account for the difference
between his and Eitner's results.

Dehydrated Mixture of that Gas and Air between which the Explosive Limits
of such a Mixture lie._--(Teclu).
