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.
I find your letter on my arrival at Grasmere, namely, dated on the 29th of June, since which time to the present, with the exception of the last few days, I have been more unwell than I have ever been since I left school. For many days I was forced to keep my bed, and when released from that incarceration, I suffered most grievously from a brace of swollen eyelids, and a head into which, on the least agitation, the blood was felt as rushing in and flowing back again, like the raking of the tide on a coast of loose stones. However, thank God, I am now coming about again.
That Tom receives such pleasure from natural scenery strikes me as it does you. The total incapability which I have found in myself to associate any but the most languid feelings, with the God-like objects which have surrounded me, and the nauseous efforts to impress my admiration into the service of nature, has given me a sympathy with his former state of health, which I never before could have had. I wish, from the bottom of my soul, that he may be enjoying similar pleasures with those which I am now enjoying with all that newness of sensation; that voluptuous correspondence of the blood and flesh about me with breeze and sun-heat, which makes convalescence more than repay one for disease.
I parted from Poole with pain and dejection, for him, and for myself in him. I should have given Stowey a decided preference for a residence. It was likewise so conveniently situated, that I was in the way of almost all whom I love and esteem. But there was no suitable house, and no prospect of a suitable house.
