its full meaning— that is, the " origin of organic forms by descent with 

 modifications " — as the only complete explanation of tlie phenomena of 

 geological succession, and therefore as the mode of operation of the divine 

 energy in the process of creation. 



Our master in geology is taken from us. Let us hope that if his full 

 mantle ma}^ not fall on any one, it may at least be parted among us.
