The moon suffers the interposition of the opaque earth.
The crucibles or pots used for the production of optical glass very closely resemble those used in the manufacture of flint glass for other purposes; they are " covered " and the molten materials are thus protected from the action of the furnace gases by the interposition of a wall of fireclay, but as crucibles for optical glass are used for only one fusion and are then broken up, they are not made so thick and heavy as those used in flint-glass making, since the latter remain in the furnace for many weeks.
But the impious project was, by divine interposition, checked.
There were risings in 1895 and in 1898-1902, the latter ceasing with American interposition.
However at present we have no reliable test to exclude interposition of the adductor aponeurosis.
