Note 455:2 — Chapter XVII
Reading edition
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."
