My dear Sir
I think I shall not be able ultimately to approve so unreservedly of Zinc roofs or roofs of copper or any metallic substance as I did yesterday in the first thought but by the time I have your queries I shall have settled my mind. This does not in any way influence what was said about bearing of brass & iron &c &c1[.]
