A second case was an account of several varieties, raised by the
author from several species of Primula, which had spontaneously
yielded a full complement of seed, although the parent plants had
been carefully protected from the access of insects. This
account was published before I had discovered the meaning of
heterostylism, and the whole statement must have been fraudulent,
or there was neglect in excluding insects so gross as to be
scarcely credible.

The third case was more curious: Mr. Huth published in his book
on 'Consanguineous Marriage' some long extracts from a Belgian
author, who stated that he had interbred rabbits in the closest
manner for very many generations, without the least injurious
effects. The account was published in a most respectable
Journal, that of the Royal Society of Belgium; but I could not
avoid feeling doubts--I hardly know why, except that there were
no accidents of any kind, and my experience in breeding animals
made me think this very improbable.

So with much hesitation I wrote to Professor Van Beneden, asking
him whether the author was a trustworthy man. I soon heard in
answer that the Society had been greatly shocked by discovering
that the whole account was a fraud. (The falseness of the
published statements on which Mr. Huth relied has been pointed
out by himself in a slip inserted in all the copies of his book
which then remained unsold.) The writer had been publicly
challenged in the Journal to say where he had resided and kept
his large stock of rabbits while carrying on his experiments,
