THE TELEOLOGY OF SCIENCE 



different from those found in other fluids, when near 

 the freezing point it becomes lighter as it becomes 

 colder y so that the mass of coldest water keeps near the 

 surface becomes covered with a layer of ice lighter 

 than itself while the deeper water is heavier and sev- 

 eral degrees warmer. If its properties a little below 

 the freezing temperature were such as those of other 

 fluids, most of the rivers and oceans near our land 

 would freeze solid and never melt again, nor would 

 clouds form, or rain fall on the dry and distant land. 

 Many substances like Ice are lighter when solid than 

 when fluid, and therefore float, but no other liquid 

 than water becomes lighter as it becomes colder. 



The relation existing between vegetable life and 

 animal life, by which the former draws its subsistence 

 from the inorganic world, from water, carbon dioxide 

 and the soil, giving on the one hand the food that 

 the animal must have but cannot make, on which it 

 subsists, and on the other hand the oxygen, only by 

 breathing which it lives. The Ether, bringing heat, 

 light and life from the Sun ; the properties of the air ; 

 the earth ; our own frames wonderfully made all 

 show the work of an intelligence that rules through- 

 out, making each detail a consistent part of all. No 

 healthful and unprejudiced mind can fail to see thous- 

 ands of instances of thought and purpose manifested 

 everywhere.
