else has related a similar story. I didn't borrow it, for all that.—I made a comparison at table some time since, which has often been quoted and received many compliments. It was that of the mind of a bigot to the pupil of the eye; the more light you pour on it, the more it contracts. The simile is a very obvious, and, I suppose I may now say, a happy one; for it has just been shown me that it occurs in a Preface to certain Political Poems of Thomas Moore's published long before my remark was repeated. When a person of fair character for literary honesty uses an image such as another has employed before him, the presumption is, that he has struck upon it independently, or unconsciously recalled it, supposing it his own.
It is impossible to tell, in a great many cases, whether a comparison which suddenly suggests itself is a new conception or a recollection. I told you the other day that I never wrote a line of verse that seemed to me comparatively good, but it appeared old at once, and often as if it had been borrowed. But I confess I never suspected the above comparison of being old, except from the fact of its obviousness. It is proper, however, that I proceed by a formal instrument to relinquish all claim to any property in an idea given to the world at about the time when I had just joined the class in which Master Thomas Moore was then a somewhat advanced scholar.
