"_History is Philosophy teaching by Examples_" (Vol. v., p. 153.).--If
your correspondent T., who cannot find this passage in any of Lord
Bolingbroke's writings, will turn to the second letter of that nobleman,
"On the Study and Use of History," he will perceive that the sentence is
there quoted from Dionysius of Halicarnassus. The writer in the
_Encyclopædia Metropolitana_ evidently takes it at second-hand from this
work; and there can be no doubt that the currency of the quotation is
entirely attributable to Lord Bolingbroke's use of it. This sentence is
the text which he illustrates at much length in his historical essay.
