We do not quite understand why the articles are headed 

 by trinomial appellations, whereas the names on the plates 

 are binomial, and we do not like the spelling Bromaius 

 for D7-om(eus. This can hardly be called a case o£ following 

 the earliest spelling, but of foreswearing the practice of the 

 Latin language itself. Are we to call ^neas Aineas, or 

 Cyrus Kuros ?

Mr. Pycraft^s latest Avork, while it is of a somewhat popular 

 nature, is the first of its kind to be written from the point of 

 view of evolution. The idea is, of course, far from being new 

 to scientific men, but books written for the general public 

 have heretofore either treated the subject from a systematic 

 standpoint or at least have not taken evolution as the main 

 subject of their discourse. A glance at the table of contents 

 will shew the wide scope of the present treatise, Avliich, be- 

 ginning with an essay on the general structure of Birds, 

 their gradual development and relationships, proceeds to give 

 a most excellent account of them as tliey are at the present 

 day, their distribution, the effect of their surroundings, their 

 migration, and their life-history in general. Their inter- 

 relations with other animals and plants and their social habits
