Suggests a change in the postscript [referred to in 3423].
2 Brook Street
My dear Sir,
Thank you cordially for your letter. While thus kindly acquiescing in what I have written, I fancy I see that you are not quite satisfied with my mode of using the word path— This then I will change, & in some such fashion as follows
``This must be considered a new path of research in the great field of Life; & one which, steadily pursued by exact & patient observation, cannot fail of conducting to many important results. It is certain that some future revision & reform will be required, of all existing catalogues of species & genera.— How far this may carry us is yet doubtful,'' &c
I write, as you will see, in great haste to secure the post, & put down the above lines as suggested to me while writing them. But something like these words I shall take instead of the other sentences of which I before sent you.
Ever yours affect
- f1 3435.f1The possible dates are conjectured by the relationship to the letter from Henry Holland, 30 January  (see also n. 2, below).
- f2 3435.f2CD's letter in response to the letter from Henry Holland, 30 January , has not been found. Holland had asked CD to comment on a postscript he had written to one of the essays that he was preparing to republish as a collection (Holland 1862), since it contained a discussion of CD's work.
- f3 3435.f3Holland refers to the enclosure sent with the letter from Henry Holland, 30 January ; the enclosure has not been found, but the published note has been reproduced with that letter.
