"Thc altar was Of metal, hollow and air-tight,
and placed on hollow base or pedestal (also air
tightly which contained quantity OF OIL or wine.
Upon the base stood two statues, each holding a
vase in one hand, as represented. Pipes, as
shown by the dotted lines, communicated through
the statues with the liquid. As the air within tie
altar became dilated BY the heat, it necessarily
forced the liquid up the pipes and drove it out of
the mouths of the vases in which the pipes termi-
mated. 1t is not easy to see why the bottom OF
the altar did no, open directly into the base or re-
servor of wine, instead of the pipe that connects
them. since it would have promoted the evolution
of vapor bs, the figure represents only one OF the
numerous notifications employed.

But the tremendous evils which their impostures
induced rendered concealment on the part of the
priests indispensable. Exposure would not only
have endangered their wealth and influence, but
might have led to their exterminaton by an out
ragged and plundered people-hence the veil of re-
ligion was interposed to screen the operators and
their apparatus. aud inevitable death was the con-
sequence of undue curiosity: witness that of Al-
citIe, female of Thebes, who ridiculed the or
sies of Bacchus, and represented by the priests
as having been changed into bat; a fiction of
theirs, most likely, to conceal their having taken
her off. zEpytus nigh, be adduced as another

this by the dilata,ion of air within the cavities Of
