done this over and over ; and yet a confiderable qiian* 
tity of this Matter difcover'd it felf in the Water after 
all. Now if it thus pafs Interjiices that are fo very 
fmall and fne along with the Water, 'tis the lefs ftrange it 
fliould attend it in its paflage through the DuBs and Vef- 
fels of Plants, 'Tis true, filtering and dijiilling of 
Water intercepts and makes it quit fome of the Earthy 
Matter it was before impregnated withal : but then that 
which continues with the Water after this, is fine and 
light ; and fuch confequently as is in a peculiar manner 
fit for the Growth and Nonrifijment of Vegetables. And 
this is the Cafe of Rain Water. The quantity of terre- 
flrial Matter it bears up into the Atmofphere is not great. 
But that which it does bear up, is mainly of that light 
kind of Vegetable Matter and that too perfedly ^^Z- 
ued, and reduced to fingle Corpufiles, all fit to enter 
the Tubules and Veffels of Plants. On which Account 
*tis that this Water is fo very fertile and prolifique. 
The reafon why in this Propofition I fay only a great 
part of the terreftrial Matter that is mix'd with the Wa- 
ter, afcends up with it into the PlaiU^ is, becaufe 
all of it cannot. The mineral Matter is a great deal of 
it not only grofs and ponderous^ but fcabrous and infiexiblet 
and fo not difpofed to enter the Pores of the Roots, 
And a great many of the fimple Vegetable Particles by 
degrees unite^ and form fome of them fmall Clods or Mo- 
leculce ; fuch as thofe mentioned in H, K, and L, flicking to 
the extremities of the Roots of thofe Plants. Others of 
them intangle in a loofer manner : and form the Nubecula^ 
and green Bodies fo commonly obferved in ftagnant Wa- 
ter. Thefey when thus conjoyn'd^ are too big to enter the 
PoreSy or afcend up the Vejfels of Plants, which fingly 
they might have done. They who are converfant in 
Agriculture will eafily fubfcribe to this. They are well 
aware that, be their Earth never fo richy fo good^ and
