PROFUSE PROFUNDITY.-The following is an extract from what purports to
have been one of the speeches in a recent discussion on the explosibility of saltpetre. "That
question, sir, whether ignition and deflagration, combined with a large concatenation of
explosive substances in a deleterious mixture, ignites by contact with sulphuretted oxide of
super-cubonite of hydrogen, and solutions of mineral matter in a mass of unsophisticated
materials, is essentially assimilated to the question by the illustrious Pantagorus whether the
hybernal frigidity of the antipodes, passing in an orthogonal line through the homogeneous
solidity of the centre, might warm the superficial convexity of our heals by a soft
antiporistasis." - (Interrupted by cries of 'The question,' & c.)
