_Singing of Swans_ (Vol. ii., p. 475.).--If your correspondent T.J. will
turn to Erman's _Travels in Siberia_ translated by Cooley, vol. ii. p. 43.,
he will find that the singing of swans is by no means so groundless a
notion as Bp. Percy supposed. _Erman_ says the notes of the Cygnus Olor are
most beautifully clear and loud--"and that this bird, when wounded, pours
forth its last breath in such notes, is now known for certain." There is
more also to the same purpose.
