from which fuch loofe fubftances were educed, and not to their 
fituation with regard to the fea. To thefe fecondary fubfidences 
we may afcribe irregular and contrary inclinations of our lodes. 
Thirdly, When it was determined that an univerfal deluge fhould 
deftroy all terreftrial animals, excepting only a fmall number pre- 
ferred in order to reftore the feveral fpecies : to produce this de- 
luge, the fea mod: probably was the chief inftrument ; its bottom 
inflated, and raifed fo as to throw its waters over the higheft moun- 
tains, covering them as a garment. When the Divine Juftice was 
fatisfled, the bottom of the fea returned nearly to its former level, 
yet not fo exactly ', but that it left fome parts above the fea (now 
iflands or hills) which were before part of the oceans bed ; the 
firata of thofe parts were therefore greatly disjointed, fome inclin- 
ing one way, fome another, fome quite reverfed. To this dreadful 
cataftrophe are we to attribute many irregularities of the firata , 
which have no correfpondence or the lead relation to the primary 
fubfidences. 
But whatever was the inftrumental caufe of the deluge, that there 
has been a deluge is the united voice of tradition, of Scripture, and 
of nature ; and from fad it appears, that this deluge diflolved all 
clays, earths, falts, and the fofter {tones, and muft have occafloned 
great ebullitions and exploflons among the pyrites, falts, and ful- 
phurs, where-ever its waters pierced; and hence happened very con- 
flderable lubfldences in the protuberant parts of our globe, where 
the fea never before reached fo as to affed the firata. 
Laftly, a few fubfidences may have happened fince the deluge, 
from the fame exhaufting diffolvent powers of water, inundations, 
or by the force of earthquakes, but none could happen either firft 
or laft, from whatever caufe, or at whatever time, without altering 
the fituation of all folids within their reach, in proportion to the 
force with which they aded upon the adjacent grounds.

Of Metals found in Cornwall ; and jirfi of 'Tin. 
H AVING examined the fiflures and the lodes, and their feveral 
properties moft worthy of notice, we muft proceed in the 
next place to the metals which our Cornifti lodes contain. 
Of metals Tin is the lighted:, and therefore fhould be the firftin 
our fcale, if there were no other reafon than the ufual method of 
ranging metals according to their fpecific gravity ; but tin would 
otherwife deferve the firft notice here, becaufe it is in a manner the
