 THE GENEALOGY OF ANIMALS. 1 



CONSIDERING that Germany now takes the lead of the 

 world in scientific investigation, and particularly in 

 biology, Mr. Darwin must be well pleased at the rapid 

 spread of his views among some of the ablest and most 

 laborious of German naturalists. 



Among these, Professor Haeckel, of Jena, is the Cory- 

 phaeus. I know of no more solid and important contri- 

 butions to biology in the past seven years than Haeckel's 

 work on the Radiolaria, and the researches of his dis- 

 tinguished colleague Gegenbaur, in vertebrate anatomy ; 

 while in Haeckel's Generelle Morphologic there is all 

 the force, suggestiveness, and, what I may term the 

 systematizing power, of Oken, without his extravagance. 

 The Generelle Morphologic is, in fact, an attempt to put 

 the doctrine of Evolution, so far as it applies to the 

 living world, into a logical form ; and to work out its 

 practical applications to their final results. The work 

 before us, again, may be said to be an exposition of the 

 Generelle Morphologic for an educated public, consist- 

 ing, as it does, of the substance of a series of lectures
