None of us would have admitted that we believed in stone or elixir, the old Oxfordshire clergyman excited no belief, yet one among us certainly laboured with crucible or athanor.

There was no conflagration but a terrible fire, burning in a big furnace with reflectors, which as I have since learned are called athanors.
