verted into nítrum. Just as the sea, in flowing of its own will over the soil
of this same Egypt, is changed into salt, so also the Nile, when it overflows
in the dog days, is converted into nitrum when it flows into the nítrum pits.
The solution from which nitrum is produced is obtained from fresh water
percolating through nitrous earth, in the same manner as lye is made from
fresh water percolating through ashes of oak or hard oak. Both solutions
are taken out of vats and poured into rectangular copper caldrons, and are
boiled until at last they condense into nitrum.
