WHAT is LIFE' 25 



the formation of new cilia, the preparation for increase 

 by the encysted form, the division into nuclei and gem- 

 mules, are all examples of this, analogous to the forma- 

 tion of new structures in the higher animals. The power 

 to produce these changes is not material but spiritual. 



15. Thus our first lesson in Biology brings us to the 

 confines of a spiritual world. We look across the gulf 

 which philosophy and science cannot bridge over except 

 by revealed truth, but the telescope of faith can see re- 

 alities on the other side as numerous, as diversified, and 

 as true as the objects of sense which can be weighed and 

 measured by our physical instruments. We see also the 

 care and providence of a Supreme Creator. Astronomy 

 adds emphasis to the Psalmist's declaration, "The heav- 

 ens declare the glory of God; and the firmament showeth 

 his handy-work." And Biology indorses the sentiments 

 of his eloquent utterances respecting living creatures : 

 " O Lord, how manifold are thy works ! in wisdom hast 

 thou made them all : the earth is full of thy riches. So 

 is this great and wide sea, wherein are things^ creep- 

 ing innumerable, both small and great beasts. There 

 go the ships : there is that leviathan, whom thou hast 

 made to play therein. These all wait upon thee ; that 

 thou mayest give them their meat in due season. That 

 thou givest them they gather : thou openest thine hand, 

 they are filled with good. Thou hidest thy face, they are 

 troubled : thou takest away their breath, they die, and 

 return to their dust. Thou sendest forth thy spirit, they 

 are created: and thou renewest the face of the earth. 

 The glory of the Lord shall endure forever : the Lord 

 shall rejoice in his works."
