Dear Mr. Poulton,--I return herewith (but separately) the "proofs" I
have of Weismann's Essays. The last critical one is rather heavy, and
adds nothing of importance to the earlier one on Duration of Life. I
enclose my "Note" on the subject, which was written, I think, about
1867, certainly before 1870. You will see it was only a few ideas jotted
down for further elaboration and then forgotten. I see however it _does_
contain the germ of Weismann's argument as to duration of life being
determined by the time of securing continuance of the species.--Yours
faithfully,
A.R. WALLACE.

_Frith Hall, Godalming. January 20, 1889._
My dear Mr. Poulton,--My attention has been called by Mr. Herdman, in
his Inaugural Address to the Liverpool Biological Society, to Galton's
paper on "Heredity," which I read years ago but had forgotten. I have
just read it again (in the _Journal of the Anthropological Institute_,
Vol. V., p. 329, Jan., 1876), and I find a remarkable anticipation of
Weismann's theories which I think should be noticed in a preface to the
translation of his book.[17] He argues that it is the undeveloped germs
or gemmules of the fertilised ovum that form the sexual elements of the
offspring, and thus heredity and atavism are explained. He also argues
that, as a corollary, "acquired modifications are barely if at all
inherited in the correct sense of the word." He shows the imperfection
of the evidence on this point, and admits, just as Weismann does, the
heredity of changes in the parent like alcoholism, which, by permeating
the whole tissues, may _directly_ affect the reproductive elements. In
fact, all the main features of Weismann's views seem to be here
anticipated, and I think he ought to have the credit of it.
Being no physiologist, his language is not technical, and for this
reason, and the place of publication perhaps, his remarkable paper
appears to have been overlooked by physiologists.
I think you will find the paper very suggestive, even supplying some
points overlooked by Weismann.--Yours faithfully,
A.R. WALLACE.
