part by frequently repeating it, or a thousand other illustrations
of the same process, we see at once that there is truth in the
cynical definition of a man as a 'bundle of habits.' And the same,
of course, is true of animals." {55a}

From this Mr. Romanes goes on to show "that automatic actions and
conscious habits may be inherited," {55b} and in the course of doing
this contends that "instincts may be lost by disuse, and conversely
that they may be acquired as instincts by the hereditary
transmission of ancestral experience."

On another page Mr. Romanes says:-

"Let us now turn to the second of these two assumptions, viz., that
some at least among migratory birds must possess, by inheritance
alone, a very precise knowledge of the particular direction to be
pursued. It is without question an astonishing fact that a young
cuckoo should be prompted to leave its foster parents at a
particular season of the year, and without any guide to show the
course previously taken by its own parents, but this is a fact which
must be met by any theory of instinct which aims at being complete.
Now upon our own theory it can only be met by taking it to be due to
inherited memory."

A little lower Mr. Romanes says: "Of what kind, then, is the
inherited memory on which the young cuckoo (if not also other
migratory birds) depends? We can only answer, of the same kind,
whatever this may be, as that upon which the old bird depends."
