He has naturally been welcomed by English Charles-Darwinians;
for if his view can be sustained, then it can be contended that use
and disuse produce no transmissible effect, and the ground is cut
from under Lamarck's feet; if, on the other hand, his view is
unfounded, the Lamarckian reaction, already strong, will gain still
further strength. The issue, therefore, is important, and is being
fiercely contested by those who have invested their all of
reputation for discernment in Charles-Darwinian securities.
Professor Weismann's theory is, that at every new birth a part of
the substance which proceeds from parents and which goes to form the
new embryo is not used up in forming the new animal, but remains
apart to generate the germ-cells--or perhaps I should say "germ-
plasm"--which the new animal itself will in due course issue.
Contrasting the generally received view with his own, Professor
Weismann says that according to the first of these "the organism
produces germ-cells afresh again and again, and that it produces
them entirely from its own substance.
