deavored to show ; but he may refer here to 

 the labors of Barrande, perhaps unrivalled in 

 extent and accuracy, which show that in the 

 leading forms of life in the older geological 

 formations the succession is not such as to 

 correspond with any of the received theo- 

 ries of derivation.* Even evolutionists, when 

 sufficiently candid, admit their case not proven 

 by geological evidence. Gaudry, one of the 

 best authorities • on the Tertiary mammalia, 

 admits the impossibility of suggesting any 

 possible derivation for some of the leading 

 groups, and Saporta, Mivart, and Le Conte 

 fall back on periods of rapid or paroxysmal 

 evolution scarcely differing from the idea of 

 creation by law, or mediate creation, as it has 

 been termed. 



Thus the utmost value which can be attached 

 to Haeckel's argument from analogy w.ould be 

 that it suggests a possibility that the processes 

 which we see carried on in the evolution of the 

 individual may, in the laws which regulate them, 

 be connected in some way more or less close 

 with those creative processes which on the

 on evolution should study Brrra-de's Memoirs on the Silurian Trilo- 

 bites, Cephahpods, and Brachiopods.
