Criticises Mr. Charles Morris's view that the earliest animals, like the 

 youngest stage of animal life generally, had no hard parts to i)reserve, 

 and that the sudden appearance of tribes was simply the appearance 

 of species having hard or stony secretions. One difficulty in the way 

 of the theory is presented by the existence of limestone formations of 

 great extent in the Archean which most geologists suppose to be of or- 

 ganic origin, and the existence also of phosphate of lime in large quan- 

 tities which also is material of possible organic origin. [kSee Morris, 

 Charles.)
