creafe that that In M. which flood in the thinner deJliWd 
Water^ had done. And, which is not lefs confiderable, 
had not drawn off half the ^antity of Water that that 
had. 
Why, in the beginning of this Article, I limit the 
Proportion of the Augment of the Plant to the ^antity 
oi proper terreftrial Matter in the Water^ is, becaufe all^ 
even the Vegetable Matter^ to fay nothing of the M/- 
neral^ is not proper for the Nourifliment of every Plant. 
There may be, and doubtlefs are, fome Parts in diffe- 
rent Species of Plants^ that may be much alike, and fo 
owe their fupply to jhe fame common Matter : but *tis 
plain all cannot. A»d there are other Parts fo differing^ 
that 'tis no ways credible they (hould be formed all out 
of the fafne fort of Corpufcles. So far from it, that there 
want not good Indications, as we fhall fee by and by, 
that every Kind of Vegetable requires a peculiar and fpe^ 
cijick Matter for its Formation and NouriJJ.ment, Yea, 
each Part of the fame Vegetable does fo : and there are 
very many and different Ingredients go to the Compofition 
of the fame individual Plant. If therefore the 5(3/7, 
wherein any Vegetable or Seed is planted, contains all or 
moft of thefe Ingredients, and thofe in due quantity^ 
'twill grow and thrive there : otherwife 'twill not. If 
there be not as many forts of Corpufcles as are requilite 
for the Conjiitution of the main and more effential Parts 
of the Plant, 'twill not profper at all. If there be thefe^ 
and not in fufficient Plenty, 'twill ftarve, and never ar- 
rive to its natural Stature. Or if there be any the lefs 
neceffary and effential Corpufcles wanting, there will be 
fome Failure in the Plant : 'twill be defedtive in Tajle^ 
in Smell, in Colour, or fome other way. But tho' a 
?r raSl of Land may happen not to contain Matter pro- 
per for the Conjiitution of fome one peculiar kind of ; 
Plant : yet it may for feveral others, and thofe much dif^ \
