Since the foregoing article was sent to the press, I have received
a letter from Arthur Strickland, Esq., in which he informs me that a
German naturalist lias published a pamphlet to prove that the so-called
Polish Swan is only an albino variety of the common species. I am
unable at present, not having seen the work, to do more than record
the circumstance of its publication, but it seems to m e , ' a s at present
advised,' that the fact of the young having been procured in different
instances in the white plumage, is sufficient, in connection with the
other peculiarities mentioned by Yarrell, to constitute the present a
distinct bird.
