[452:1] He seems, from this and other notices, to have been occasionally absent in his habits; but there is no such collection of practical illustrations of this failing, as we possess in the case of Smith and others. I only remember having heard of one trifling instance, of which I had an account from an eye-witness. Hume had been dining with Dr. Jardine, and there had been much conversation about "internal light." In descending the stair leading from the Doctor's "flat," when he left the party, Hume failed to observe that after so many flights which reached the street door, there was, according to a not uncommon practice, another flight of stairs leading to the cellars. He continued his descent, accordingly, till the very end, where some time afterwards he was found in extreme darkness and perplexity, wondering how it was that he could find no outlet. The circumstance bore rather curiously on some opinions he had been maintaining, and Jardine said, shaking his head, "Oh David! where is your internal light?"

[455:2] MS. R.S.E. In citing this letter above, vol. i. p. 98, it is stated that on one MS. there is noted a supposition that it was addressed to Dr. Traill—on another that it was addressed to Gilbert Stuart. I now think it must have been addressed to Dr. John Stewart, Professor of Natural Philosophy in the University of Edinburgh, and that it related to his "Remarks on the Laws of Motion and the Inertion of Matter," published in "Essays and Observations physical and literary, read before a Society in Edinburgh."
