The charitable institution you have proposed to the city of New Orleans would undoubtedly be valuable, and all such are better managed by those locally connected with them. The great wealth of that city will insure its support, and the names subscribed to it will give it success. For a private individual, a thousand miles distant, to imagine that his name could add anything to what exhibits already the patronage of the highest authorities of the State, would be great presumption. It will certainly engage my best wishes, to which permit me to add for yourself the assurances of my respect. TO THOMAS COOPER, ESQ. MONTICELLO, July 10, 1812. DEAR SIR,--I received by your last post through Mr. Hall, of Baltimore, a copy of your introductory lecture to a course of chemistry, for which accept my thanks. I have just entered on the reading of it, and perceive that I have a feast before me. I discover from an error of the binder, that my copy has duplicates of pages 122, 123, 126, 127, and wants altogether, pages 121, 124, 125, 128, and forseeing that every page will be a real loss, and that the book has been printed at Carlisle, I will request your directions to the printer to enclose those four pages under cover to me at this place, _near Milton_. You know the just esteem which attached itself to Dr. Franklin's science, because he always endeavored to direct it to something useful in private life. The chemists have not been attentive enough to this. I have wished to see their science applied to domestic objects, to malting, for instance, brewing, making cider, to fermentation and distillation generally, to the making of bread, butter, cheese, soap, to the incubation of eggs, &c. And I am happy to observe some of these titles in the syllabus of your lecture. I hope you will make the chemistry of these subjects intelligible to our good house-wives. Glancing over the pages of your book, the last one caught my attention, where you recommend to students the books on metaphysics. Not seeing De Tutt Tracy's name there, I suspected you might not have seen his work. His first volume on Ideology appeared in 1800. I happen to have a duplicate of this, and will send it to you. Since that, has appeared his second volume on grammar and his third on logic. They are considered as holding the most eminent station in that line; and considering with you that a course of anatomy lays the best foundation for understanding these subjects, Tracy should be preceded by a mature study of the most profound of all human compositions, "Cabanis's Rapports du Physique et du moral de l'homme."
