_Take purified nitre powdered half a pound, crabs eyes prepared four
ounces, cinnabar of antimony finely prepared two ounces, calomel one
drachm, and mix them._
This is the celebrated antispasmodic powder of the great _Stahl_, with
some considerable amendment by means of the calomel; which, in the
course of a long practice, I have found the most beneficial for fevers.
There is not a kind of fever to which mankind are subject, either at
shore or at sea, but what this powder may with safety and with great
benefit be applied. A scruple, or half a drachm is a dose, and which may
be repeated, as the ardency of the fever shall require.
