My dear Mr Wallace
I thank you very much for your paper on "The origin of human races".
The argument is quite new to me, & opens up an entirely new field of enquiry. You have [?] quite a new light on the subject of Natural Selection, & on the history of man.
You are no doubt right in your estimate of the strength [] of Harris'[?] position in assigning a [illeg.] subclass to man -- but you do not say whether you think clarification can be based on any but purely morphological considerations, which is the tendency of modern systematics[?]. My suspicion is that for practical purposes morphology must, in the present state of science, be our only [] safe guide. I do not thereby imply that other considerations may not have more value, but we have no means of estimating the presence[?] of mind of the lower mammals though these do differ so materially.
Very sincerely yours | J. D. Hooker [signature]1
