FUTURE ABODE OF ANIMALS 225 



Jupiter, Saturn, Uranus, and Neptune are composed 

 of like substances as our earth which is one in 

 common with the others. 



They have a resemblance to our earth in various 

 ways. We can know of one that its surface rises 

 into inequalities, that it swells into mountains, and 

 stretches into valleys. Of another that it is sur- 

 rounded by an atmosphere which may support the 

 respiration of animals. Of a third, that clouds are 

 formed and suspended over it, which may minister 

 to it all the bloom and luxuriance of vegetation. 

 And of a fourth that a white color spreads over its 

 northern regions, as its winter advances and that 

 on the approach of summer their whiteness is dis- 

 sipated, giving proof that there are rains, snow, 

 heat, cold, and seasons suited for vegetable and 

 animal life. 



Herschel says, " When we contemplate the con- 

 stituents of the planetary system, they are bound up 

 in one chain, interwoven in one web of mutual re- 

 lation and harmonious agreement, subjected to one 

 pervading influence which extends from the centre 

 of the farthest limits of that great system, of 

 which all of them, the earth included, must hence- 

 forth be regarded as members."
