Fig. 5- V W X Y Z reprefents two grains of Sand that 
were (till joyned to each other, the one is defcribed by 
V WX wherein you may obferve feveral points, and par- 
ticularly between W and X, and the other is ftown by

flits in them , I do fuppofe that might happen by the 
breaking or divifion of thefe (andy particles from one

That piece of the Red Stone that ftill remain d entire

pieces^ there flew a fpark of Fire out of it, 
I made a fmall bit of it fo hot, that it was glowing, and

particles of Sand would be feparated thereby, but that 
the red matter alfo which confolidated the Sand would

Sand was as ftrong as if it had never been in the Fire, and 
was alfo furrounded with the red matter 5 but in (bmeof
