information, of the sort desired by most persons, in the smallest compass. 
Next comes Zowhee, a minor article, on a part of one page, with an 
explanation of the word, identification of the bird, a figure of its head from 
Swainson, remarks on the species of Pzdzlo, references with the usual 
small capitals to Frncu, BUNTING and CATsBIRD (which the cry of some 
species calls up), and the synonyms of Chewink and Ground-Robin 
(though we miss ‘Joree,’ a less known nickname of P. erythrophthalmus). 
Next comes 7vrachea, a 2$-page article by Dr. Gadow defining that organ, 
and noting its main modifications in many different groups of birds, with 
cross-references to Laryzx and Syrizx. Next happens to come Zvracheo- 
phones; we give it as a model of curt, formal definition, in a case where 
the author has nothing further to say: 
“TRACHEOPHONES (by some written Tracheophone or Tracheo- 
phont) Johannes Miiller’s name (Abhandl. k. Akad. Berlin, Phys. Kl. 
1847, p- 367) for the second of his three groups ot PASSERINI, having 
the trachea furnished with one or two pairs of vocal muscles, and 
those lateral (cf SYRINX, p. 940).” 
These examples must suffice. To go through any considerable portion. 
of this ‘Dictionary’, applauding the author’s strong and clear statements 
of fact, would be futile, after what has been said; and to pick up for dis- 
cussion or criticism his expressions of opinion (which he sedulously 
distinguishes from statements of fact) in cases where they may differ 
from our own, or be open to revision, would be fatuous; for that would 
be to write another, and presumably a much inferior, treatise upon the 
same subjects. Nor have we any intention, in reviewing a work, the 
equal of which for accuracy we have not seen before in any instance of 
similar magnitude, of pricking pin-holes; that may be left to literary 
chiffonniers whose tastes differ from our own, and who have possibly time 
to waste. We finish this very inadequate sampling of the alphabetical 
entries by calling attention to the Index with which the work concludes — 
a valuable feature, which theoretically should be superfluous in a ‘ Dic- 
tionary,’ but which in this case goes far toward obviating an inconvenience 
of which some may justly complain — that resulting from comparative 
fewness of the entry-words. Thus, for examples: Twdznares is entered, 
with a 4-line definition, including cross-references to Albatross and 
Petrel; but the Index gives under Tudznares 32 places where something 
may be found about the birds which come under that head. Ufufa is. 
not entered, as Latin generic names, when not English also, are not within 
the scope of the work for formal entry; but under Ufufa in the Index 
are 24 references to pages where birds of that genus are treated in the 
text. 
The most important article in the whole work is the Introduction, now 
supplied with Part IV, of course to be bound in its proper place, as above 
indicated. This, with the Index to itself, runs pp. z-72¢ (slanting Arabic 
figures, as if italics, to distinguish this matter from pp. 1-1088 of main 
text). It is difficult to characterize this piece of work justly without
