is, when stripped of surplusage, as follows:--

"The modification of species has been mainly effected by accumulation of
spontaneous variations; it has been aided in an important manner by
accumulation of variations due to use and disuse, and in an unimportant
manner by spontaneous variations; I do not even now think that
spontaneous variations have been very important, but I used once to think
them less important than I do now."

It is a discouraging symptom of the age that such a system should have
been so long belauded, and it is a sign of returning intelligence that
even he who has been more especially the _alter ego_ of Mr. Darwin should
have felt constrained to close the chapter of Charles-Darwinism as a
living theory, and relegate it to the important but not very creditable
place in history which it must henceforth occupy. It is astonishing,
however, that Mr. Wallace should have quoted the extract from the "Origin
of Species" just given, as he has done on p. 412 of his "Darwinism,"
without betraying any sign that he has caught its driftlessness--for
drift, other than a desire to hedge, it assuredly has not got. The
battle now turns on the question whether modifications of either
structure or instinct due to use or disuse are ever inherited, or whether
they are not. Can the effects of habit be transmitted to progeny at all?
We know that more usually they are not transmitted to any perceptible
extent, but we believe also that occasionally, and indeed not
infrequently, they are inherited and even intensified. What are our
grounds for this opinion? It will be my object to put these forward in
the following number of the _Universal Review_.

THE DEADLOCK IN DARWINISM--PART II {29}

At the close of my article in last month's number of the _Universal
Review_, I said I would in this month's issue show why the opponents of
Charles-Darwinism believe the effects of habits acquired during the
lifetime of a parent to produce an effect on their subsequent offspring,
in spite of the fact that we can rarely find the effect in any one
generation, or even in several, sufficiently marked to arrest our
attention.

I will now show that offspring can be, and not very infrequently is,
affected by occurrences that have produced a deep impression on the
parent organism--the effect produced on the offspring being such as
leaves no doubt that it is to be connected with the impression produced
on the parent. Having thus es
