Or again: 
Decay of some leaves others free to grow 
And thus the sum of things rests unimpaired 
Book II p. 79, 
And again: 
The store of elements material, 
_ Admits no diminution, no increase; 
Book II p. 86. 
No modern scientific man could state more clearly than 
Lucretius does, the ideas which prevail at present as 
to the motions of the atoms, Says Tyndall of the parti- 
cles in a mass of iron: ‘‘There is space between them, they 
collide, recoil, they oscillate.” 
The poet states it thus: 
No place of rest is found 
To primal bodies through the vast profound, 
And, finding none, they cease not ceaseless rounds. 
Part forced together, wide asunder leap; 
From closer blow part, grappling with their kind, 
In close affinities unite and form 
Bodies of various figure—varied forms diverse. 
Book I p. 80. 
Again: 
For infinite atoms, in a boundless void, 
By endless motions build the frame of things. 
Book II p. 82 
All things are made up of these atoms: 
The same elements constitute the air, 
The sun, the earth and animals and plants, 
And other things by union various. 
Book I p. 63. 
Lucretius makes much use of what he calls the ‘‘seeds 
of heat,’ that is, the atoms which by their concurrence 
form heat. Thus he explains the heat resulting from 
friction. 
The neighbor top of trees swayed by the wind 
Are creaking rubbed, till by attrition they 
Burst into flower of flame; not that the fire 
Dwells in the wood but rather seeds of heat
