IDENTICAL CHANGES 



Then because all substance is built up of P. S. 

 (Prop. XIX, B. 1) ; 



And the change of void matter into organized 

 Matter provides more room, while the change of 

 organized Matter into void matter requires more 

 room (Prop. XX, B. 1), 



Therefore, the dismemberment and reorganiza- 

 tion must be simultaneous in the Universe, and in 

 any identity wherein it takes place. (Axiom 3.) 



Again, because every change of organized bodies 

 in that which constitutes their organization must 

 be particle by particle, therefore every change in 

 organization requires time. (Prop. XV, B. 2.) 



Therefore, any current of void spheres effecting 

 a change in organized substances must be checked 

 up in velocity. (Theorem.) 



This is in a manner illustrated by every current 

 of wind and water. If two floats are suspended 

 by a long string, in a current side by side, some 

 distance apart, the current will soon make them 

 come together. Or if two floats are connected by a 

 string and turned adrift, down an even current, 

 one ahead of the other, they will soon be together. 



Then under the alternate Hypothesis any organ- 

 ized body of material, anywhere in the Universe, 

 must lessen the velocity of the alternate flow in 

 its vicinity. But this checking up cannot alter 

 the normal velocity of a universal current (normal 

 to that vicinity) any more than a boat anchored 

 in the Mississippi will govern the amount of water 

 discharged by the river. Evidently then when
