But Mountains may alfo be produced 
otherwife, as by Eruption of Fires caft- 
ing out Ajfhcs and Stones together with 
brittiftone and bituminous fubftaneesj 
as alfo by theimpetuoufnefs ofRain^ and 
Torrents, whereby the Ston’j beds, being 
cracked before by the viciffitudes of 
heat and cold, are precipitated 5 but 
Eartf^ onesj that had been fplit by ex- 
ceflive heats, are diifolved into many 
pieces. 
Hence it appears, that there are two 
main kinds of Hills and Hillocks: om, 
of thofe which are made up of Beds* of 
which there are again two forts, fomc 
having abundance of Stony, others of 
Earthy beds j the other is of fuch,which 
rife up without any orders out of Frag¬ 
ments of beds and parts broken off. 
.Whence it may eafily be made out, 
1. That all Mountains at this day 
have not exifted from the beginning of 
things. 
2. That Vegetation hath no place in 
Mountains. 
3. That the Stones of Mountains have 
nothing common (befidcs fome fimili-, 
tude of hardnefsj with the bones of A- 
nimalsj
