Sir John Herschell, a more competent authority, said of Young's discovery, that it was sufficient of itself to have placed its author in the highest rank of scientific immortality.
The situation seemed to Mr.Murray to warrant the following letter: _John Murray to the Right Hon.

George Canning_.
_September 25, 1807._ Sir, I venture to address you upon a subject that is not, perhaps, undeserving of one moment of your attention.

There is a work entitled the _Edinburgh Review_, written with such unquestionable talent that it has already attained an extent of circulation not equalled by any similar publication.

The principles of this work are, however, so radically bad that I have been led to consider the effect that such sentiments, so generally diffused, are likely to produce, and to think that some means equally popular ought to be adopted to counteract their dangerous tendency.

But the publication in question is conducted with so much ability, and is sanctioned with such high and decisive authority by the party of whose opinions it is the organ, that there is little hope of producing against it any effectual opposition, unless it arise from you, Sir, and your friends.
