I received a very kind letter from Godwin, in which he says that he never thinks of you but with a brother's feeling of love and expectation. Indeed, I am sure he does not. I think of translating Blumenbach's Manual of Natural History: it is very well written, and would, I think, be useful both to students, as an admirable direction to their studies, and to others it would supply a general knowledge of the subject. I will state the contents of the book: 1. Of the naturalia in general, and their divisions into three kingdoms. 2. Of organised bodies in general. 3. Of animals in general. 4. Of the mammalia. 5. Birds. 6. Amphibious. 7. Fishes. 8. Insects. 9. Worms. 10. Plants. 11. Of minerals in general. 12. Of stones and earthy fossils. 13. Of mineral salts. 14. Combustible minerals. 15. Of metals. 16. Petrifactions. At the end there is an alphabetical index, so that it is at once a natural history and a dictionary of natural history. To each animal, etc., all the European names are given, with of course the scientific characteristics. I have the last edition, "i.e.", that of April, 1799. Now, I wish to know from you, whether there is in English already any work of one volume (this would make 800 pages), that renders this useless. In short, should I be right in advising Longman to undertake it? Answer me as soon as you conveniently can. Blumenbach has been no very great discoverer, though he has done some respectable things in that way, but he is a man of enormous knowledge, and has an "arranging" head. Ask Beddoes, if you do not know. When you have leisure, you would do me a great service, if you would briefly state your metaphysical system of impressions, ideas, pleasures, and pains, the laws that govern them, and the reasons which induce you to consider them as essentially distinct from each other. My motive for this request is the following:--As soon as I "settle", I shall read Spinoza and Leibnitz, and I particularly wish to know wherein they agree with, and wherein differ from you. If you will do this, I promise you to send you the result, and with it my own creed. God bless you! S. T. COLERIDGE. Blumenbach's book contains references to all the best writers on each subject. My friend, T. Poole, begs me to ask what, in your opinion, are the parts or properties in the oak which tan skins? and is cold water a complete menstruum for these parts or properties? I understand from Poole that nothing is so little understood as the chemical theory of tan, though nothing is of more importance in the circle of manufactures; in other words, does oak bark give out to cold water all those of its parts which tan? Coleridge and his family at last settled down at Greta Hall in July, 1800, and he thus writes to Josiah Wedgwood of the event. LETTER 93. To JOSIAH WEDGWOOD July 24, 1800. My dear sir,
