Singing of Swans

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.
