8. “_Some profound connexions must exist between the utility of a
variation and its actual appearance, or the direction of the variation
of a part must be determined by utility._”[21]
[21] p. 18.
9. That “germinal selection performs the same services for the
understanding of observed transformations ... that a heredity of
acquired characters would perform without rendering necessary so
_violent an assumption_!”[22] (Italics mine.)
[22] p. 40.
10. Weismann speaks warmly of Professor Lloyd Morgan for his caution
and calmness of judgment but complains of him that he “has not been
able to abandon completely the heredity of acquired characters.”[23]
[23] p. 56.
11. As to passive effects of environment, etc., he says “the Lamarckian
principle is here excluded _ab initio_.”[24]
[24] p. 11.
12. “It seems to me that a hypothesis of this kind (Lamarckism) has
performed its services and must be discarded the moment it is found to
be at hopeless variance with the facts.”[25]
[25] p. 17.
I have only to add here that several years ago I wrote to Weismann
drawing his attention to some facts I had observed which seemed to me
to be instances of use-inheritance, and I received a reply in polite
but brief and Prussian terms to the effect that the facts referred to
must be capable of some other interpretation, for _the machinery for
their transmission did not exist_.
Each of these twelve quotations from Weismann’s essay is important from
the present point of view, and shows how far neo-Darwinians are likely
to promote the greater glory of Darwin, and though more than a quarter
of a century elapsed between this essay and his death Weismann was not
the man to have repudiated any of these strong statements.
