'Charles Townsend, who passes for the cleverest fellow in England, is so taken with the performance, that he said to Oswald, he would put the Duke or Buccleugh under the author's care, and would make it worth his while to accept of that charge. As soon as I heard this, I called on him twice with a view of talking with him about the matter, and of convincing him of the propriety of sending that young nobleman to Glasgow; for I could not hope, that he could offer you any terms which would tempt you to renounce your professorship. But I missed him. Mr. Townsend passes for being a little uncertain in his resolutions; so, perhaps, you need not build much on this sally. 'In recompense for so many mortifying things, which nothing but truth could have extorted from me, and which I could easily have multiplied to a greater number, I doubt not but you are so good a christian as to return good for evil, and to flatter my vanity, by telling me, that all the godly in Scotland abuse me for my account of John Knox and the reformation.' Mr. Smith having completed, and given to the world his system of ethics, that subject afterwards occupied but a small part of his lectures. His attention was now chiefly directed to the illustration of those other branches of science which he taught; and, accordingly, he seems to have taken up the resolution, even at that early period, of publishing an investigation into the principles of what he considered to be the only other branch of Moral Philosophy,--Jurisprudence, the subject of which formed the third division of his lectures. At the conclusion of the Theory of Moral Sentiments, after treating of the importance of a system of Natural Jurisprudence, and remarking that Grotius was the first, and perhaps the only writer, who had given any thing like a system of those principles which ought to run through, and be the foundation of the law of nations, Mr. Smith promised, in another discourse, to give an account of the general principles of law and government, and of the different revolutions they have undergone in the different ages and periods of society, not only in what concerns justice, but in what concerns police, revenue, and arms, and whatever else is the object of law.
