of Audubon and Bachman’s great work, — an admirable one for the time 
but long since rendered antiquated and sadly incomplete through later 
increase of knowledge, — it is most fortunate that the task of preparing 
a new history of the subject from the abundant materials now at com- 
mand has been undertaken by one so thoroughly competent for the task. 
In thé way of unfavorable criticism we have only to add that the plates 
illustrating the skulls and dentition of the species described are unworthy 
of the accompanying text. -They are referred to as an attempt a’ deline- 
ation by a new process, from which with further experience probably bet- 
ter results may be expected. While the figures are highly useful and 
fairly expressive, they are artistically harsh and unpleasing. We have 
as yet evidently no short cut to excellence in the graver’s art. 
In respect to typography little more could be desired: the type is 
large and the page open and clear, while careful revision on the part of 
proof-reader and author is everywhere apparent.
