On the subject of the Mystery of the Beetle I do not propose to
pronounce a confident opinion. Atherton and I have talked it over
many and many a time, and at the end we have got no 'forrarder.'
So far as I am personally concerned, experience has taught me that
there are indeed more things in heaven and earth than are dreamed
of in our philosophy, and I am quite prepared to believe that the
so-called Beetle, which others saw, but I never, was—or is, for
it cannot be certainly shown that the thing is not still existing
—a creature born neither of God nor man.
