_Willow Bark in Ague_ (Vol. ix., p. 452.).--In the _Philosophical
Transactions_ (1835?) is a memoir by the Rev. E. Stone, of Chipping Norton,
of the salutary effects of the bark of the Duck Willow in agues and
intermittent fevers. The author states, that being dried in an oven, and
pounded, and administered in doses of one drachm every four hours in the
intervals of the paroxysms, it soon reduces the distemper; and, except in
very severe cases, removes it entirely. With the addition of one fifth part
of Peruvian bark, it {572} becomes a specific against these disorders, and
never fails to remove them. One advantage it possesses of influencing the
patient beneficially immediately it is adopted, without the necessity of
preparation previously. It is a safe medicine, and may be taken in water or
tea.
I copy the above from an entry in an old notebook. I imagine the Duck
Willow to be the Common White Willow (_Salix albæ vulgaris_) of Ray.
