My dear Sir

I shall be very glad to read your paper; but you must not trust to my judgment. I am essentially a very poor critic, as I have often found to my cost,— I am always inclined to believe all I read, & differ only after long reflection; & this is now becoming hard work for me on new subjects.— Moreover I have no mathematical knowledge of any kind or power in this line.—²

So do not trust me, but believe me yours very sincerely | C. Darwin
