But I have been interrupted in my letter by a foolish impertinent visit of one who has lately come from Scotland. He tells me that the University of Glasgow intend to declare Rouet's office vacant, upon his going abroad with Lord Hope. I question not but you will have our friend Ferguson in your eye, in case another project for procuring him a place in the University of Edinburgh should fail. Ferguson has very much polished and improved his Treatise on Refinement;[56:1] and with some amendments it will make an admirable book, and discovers an elegant and a singular genius. The Epigoniad, I hope, will do; but it is somewhat up-hill work. As I doubt not but you consult the Reviews sometimes at present, you will see in _The Critical Review_ a letter upon that poem; and I desire you to employ your conjectures in finding out the author. Let me see a sample of your skill in knowing hands by your guessing at the person.[56:2] I am afraid of Kames' "Law Tracts." A man might as well think of making a fine sauce by a mixture of wormwood and aloes, as an agreeable composition by joining metaphysics and Scottish law. However, the book, I believe, has merit; though few people will take the pains of inquiring into it. But to return to your book, and its success in this town, I must tell you---- A plague of interruptions! I ordered myself to be denied; and yet here is one that has broke in upon me again. He is a man of letters, and we have had a good deal of literary conversation. You told me, that you was curious of literary anecdotes, and therefore I shall inform you of a few that have come to my knowledge. I believe I have mentioned to you already, Helvetius's book "De l'Esprit." It is worth your reading, not for its philosophy, which I do not highly value, but for its agreeable composition. I had a letter from him a few days ago, wherein he tells me that my name was much oftener in the manuscript, but that the censor of books at Paris obliged him to strike it out. Voltaire has lately published a small work called _Candide, ou, l'Optimisme_. I shall give you a detail of it. But what is all this to my book, say you? My dear Mr. Smith, have patience: compose yourself to tranquillity; show yourself a philosopher in practice as well as profession: think on the emptiness, and rashness, and futility of the common judgments of men; how little they are regulated by reason in any subject, much more in philosophical subjects, which so far exceed the comprehension of the vulgar. ----Non si quid turbida Roma, Elevet, accedas: examenve improbum in illâ Castiges trutinâ: nec te quaesiveris extra.
