graduated chain." But I will express this more 

 satisfactorily in the terms of the French scientist, 

 M. Gaudry, director of the Museum, and a decided 

 evolutionist, who says in his Primary Fossils: " The 

 most able observers refuse to admit a single linear 

 series, beginning at the monad, continuing in due 

 course under the form of polyp, echinoderm, mol- 

 lusk, annelid, articulate, fish, reptile, bird, mammal, 

 and finishing in man. Although the mammals are 

 the most perfected of the vertebrates, the study of 

 their embryonic development does not show us that 

 they ever passed through the fish state, and through 

 the bird state. Palaeontology here confirms em- 

 bryology, when it considers itself to have discov- 

 ered in geological times, that there was not any 

 single chain of beings, but many such chains, the 

 development of which has gone on independently."

 monkeys, the apes. But we have reason to fear
