history of every animal could be largely sketched out by 

 indications and changes in the embryo, and then be verified 

 by actual research and observation in nature. Thus the 

 genesis of the tribe (Phylogenesis] and of the individual 

 ( Ontogenesis) were made to throw light upon and to reveal 

 each other. 



Another view of great interest was presented in this woik, 

 that the simpler organisms or microbes represented a primi- 

 tive condition of life not only below the distinction of sex, 

 but also below the distinction of animal and vegetable life, 

 and were really such simple forms of protoplasm that they 

 constitute a kingdom by themselves, which he calls the Pro- 

 tista and regards as the common foundation and source of 

 both animals and plants. Prof. Huxley expressed the sen- 

 timent of those capable of judging when he pronounced 

 this Morphology to be one of the greatest scientific works 

 ever published. Its influence was largely instrumental in 

 turning the tide of German thought in favor of the new 

 biology. 



Certainly after such a display of genius and labor the re- 

 quirement of some rest would appear reasonable, but it 

 seems that Prof. . Haeckel never rests. His vacations are 

 spent in excursions for scientific research and verification. 

 In the winter of 1866 he was at work among the Canary 

 Islands, and upon his return he published an interesting re- 

 port of his explorations there and on the Atlantic coasts. 



In 1867-'68 he determined to give a popular exposition 

 of the new philosophy the new view of the world. A 

 course of lectures was accordingly delivered, reported, and 

 published, which are now known the world over as The 

 Natural" History of Creation. This work has gone on 

 through revised editions from the first to the 'eighth, and 

 has been translated into English (in two volumes, by the 

 Appletons) and into every modern civilized language. Ex- 

 cepting, perhaps, some of Darwin's works, it has done more 

 than any other to make evolution known as the fundamental 

 law of the organic world. Of it, in the preface to his De- 

 scent of Man, Darwin uses these remarkable words : 



" The conclusion that man is the co-descendant with other 

 species of some ancient, lower, and extinct form is not in 

 any degree new. Lamarck long ago came to this conclu- 

 sion, which has lately been maintained by several eminent 

 naturalists and philosophers for instance, by "Wallace, Hux- 

 ley, Lyell, Vogt, Lubbock, Buchner, Eolle, and especially
