"For, if he takes his physic first,
He'll never read his rhymes."
[296] Hill says, in his pamphlet on the "Virtues of British
Herbs":--"It will be happy if, by the same means, the
knowledge of plants also becomes more general. The study of
them is pleasant, and the exercise of it healthful. He who
seeks the herb for its cure, will find it half effected by the
walk; and when he is acquainted with the useful kinds, he may
be more people's, besides his own, physician."
