My dear Hooker

I think the address does very well.—¹ W^d it not be better to insert, “zoological” (botanical evidently a misprint) after instead of before “geological, mineralogical”?²

I do not like the first sentence which you have marked with “?”.

I wrote sentence on next page before I saw the last paragraph, & now it is tautological.— I hardly understand what Duncan means. by it.—³

With respect to second sentence with “?” I never saw word “synclinoria”, & I sh^d doubt about “proof” with respect to “all great chains”— No doubt if he has shown that many mountain chains have been formed in synclinal troughs it is very important, & agrees with what Judd has lately shown.⁴

Yours affectionately | C. Darwin
