We can, therefore, conscientiously recommend Mr. Beebe’s 
work to those who are anxious for condensed information 
on the general characters and structure of ‘The Bird,’ and 
we can truly say there is no other publication with which 
we are acquainted that contains such information tm so 
readable a form and is so profusely equipped with appropriate 
illustrations. 
53. Beebe on Swans. 
[The Swans, By C. William Beebe. Reprinted from the Tenth 
Annual Report of the New York Zoological Society. 26 pp. 8vo. | 
Mr. Beebe has taken the opportunity of examples of all 
the certainly known species of Swans being exhibited in the 
Zoological Park of New York to prepare a nicely written 
essay on these ornamental birds, which fully deserve all the 
praise that he accords to them. It is illustrated by good 
text-figures, by the aid of which the seven species may 
-be easily recognised. Mr. Beebe’s statements about the 
different forms are, we believe, generally well founded, 
though we should hesitate to place entire faith in the story 
of the “dying Swan’s song” given on page 8. Mr. Beebe 
assumes that the so-called Cygnus davidi of North-east China 
is only “a variant” of Cygnus bewicki. But this is by no 
means certain, and it is quite possible, we think, that it may 
still turn out to be a good species, especially considering what 
Prof. Giglioli has written on the subject.
