Priestley, loaded with glory, was modest enough to be astonished at his good fortune, and at the multitude of beautiful facts, which nature seemed to have revealed to him alone. He forgot that her favours were not gratuitous, and if she had so well explained herself, it was because he had known how to oblige her to do so by his indefatigable perseverance in questioning her, and by the thousand ingenious means he had taken to snatch her answers from her.

Others carefully hide that which they owe to chance; Priestley seemed to wish to ascribe all his merit to fortuitous circumstances, remarking, with unexampled candour, how many times he had profited by them, without knowing it, how many times he was in possession of new substances without having perceived them; and he never dissimulated the erroneous views which sometimes directed his efforts, and from which he was only undeceived by experience.

Pondering on these lines there slowly returned to mind the words of Franklin's epitaph,

—Franklin, who, years before, had encouraged and aided the noble exile, who was ever mindful of the former's goodness to him:

The Body
of
Benjamin Franklin
Printer
(Like the cover of an old book
Its contents torn out

Lies here food for Worms
But the work shall not be lost
For it will (as he believed) appear
once more
In a new and more elegant Edition
Revised and corrected
