"Why do you call your peculiar power an infirmity?" he retorted. Then, with the utmost seriousness, he went on to say: "Everything is relative; your memory, taking it generally, is better than that of some, and poorer than that of others; as it is affected by your peculiar periods, it is in some features far stronger than the average memory, and in other features it is weaker; have you not known this?"

"Yes; I can recall any object that I have seen; its image is definite, if it has been formed in a lapse."

"But in respect to other matters than objects?"

"You mean as to thought?"

"Yes--speculation."

"In a lapse I seem to forget any mere opinion, or speculation, that is, anything not an established fact."

"Not at all," said I.

"Suppose you should hear a discussion of the tariff question; would you remember it?"

"No, sir."
