Fiirbringer's opinion, sufficient for the establishment of a 

 definite system of classification ; he propounds, however, a 

 scheme which is more in accord with what a classification of 

 Birds ought to be than many which have been put forward by 

 ornithologists, inasmuch as it takes into account the sum 

 total of structural variations. These views upon classi- 

 fication are illustrated by four plates representing the 

 affinities of the different groups. Frof. Fiirbringer discusses 

 at some length the relations of the Ratitse to other birds, 

 tabulating the points of agreement and of difference; this is 

 done with the object of discussing how far the views of Wie- 

 dersheim and others as to the diphylitic origin of Birds are 

 tenable. The summary of facts points decidedly, as Prof. 

 Fiirbringer shows, to the conclusion that the Ratitsehave not 

 been developed from one Reptilian stock (Dinosauria) and 

 the Carinatse from another (Ornithosauria), but that both 

 have originated from the same stock. The last portion of 

 the second volume is devoted to a discussion of the relation- 

 ship of Birds to the diffeient groups of Reptiles, the principal 

 points of resemblance to the various groups being shortly 

 stated in a number of paragraphs. The conclusion arrived 

 at is that Birds have not taken their rise from any group of 

 Reptiles known to us ; but that, while presenting affinities 

 more or less near to the Dinosauria, Crocodilia, and Lacer- 

 tilia, they have been derived, in common with these groups, 

 from the primitive Sauropsian stock. 



The work concludes with a bibliography, which contains 

 the titles of all the principal publications relative to the 

 anatomy of Birds.
