to the university at ten; heard Sir Charles Bell,[46] the professor of surgery,--a decent lecturer, but not remarkable. At eleven I heard the celebrated Dr. Chalmers, the professor of divinity. The old man has a heavy, strongly-marked Scotch countenance, which, however, brightens very much when he is engaged in his discourse. His manner is rather inelegant and his dialect broad Scotch and peculiar. But the matter is so rich that he carries all before him. Every word is full of thought, and he occasionally rose to a very powerful eloquence. He is much beloved, and is considered by all parties, perhaps, as the strong man of Scotland. The subject of his lecture this morning was the advantage (and the abuse) of Scripture criticism. It was a treat to hear him. He paid a high compliment, in the course of his remarks, to our Moses Stuart. The weather growing by this time more tolerable, I walked about town,--visited the Parliament House, the Library of the Writers to the Signet; passed through the Grassmarket, returned here, looked at plants with Dr. Greville; dined; received a parcel from Sir William Hooker containing a few plants I had accidentally left (a few he had given me). A very kind letter informed me that he would be in London about the same time with me (which I had in part expected, and about which hangs a tale I must write soon), and also a fine parcel of letters of introduction for me, both to persons on the way to London, and also on the Continent,--to Delessert, De Candolle, Martins, Endlicher, Humboldt, etc. Truly he is a kind man; he has laid me under lasting obligations. He asks me to say to Dr. Torrey that his Grace of Bedford is anxious to receive also the Hudsonia ericoides from New Jersey, and he will be greatly obliged if he will send a box of it to Woburn early in the spring. Attended this evening a meeting of the Royal Society, Dr. Abercrombie[47] (author of “Intellectual Powers,” etc.) in the chair. Dr. A. is at the head of the profession here; is greatly esteemed, and is a most exemplary Christian. An interesting paper was read by Professor Forbes, of whom I have spoken before; a man whom from his very youthful appearance you could never have imagined as the successful candidate to the professor’s chair against Dr. Brewster. But Dr. Brewster is no favorite in Edinburgh. Other distinguished men were there. I was introduced to Professor Christison,[48] had some pleasant conversation; promised, if practicable, to hear him lecture to-morrow at nine A.M., and look at his museum of materia medica. We had tea after the adjournment, according to the usual custom here, which is a very pleasant one. I only count upon two days more in Edinburgh, and have yet much to do. I am anxious to reach London, where I hope there are letters for me. Good-night. May God bless you all, and keep you. MELROSE, January 10, 1839, Thursday evening.
