of folid or hardned froth,or a cogeries of very fmall bubbles confolidated 
in that form, into a pretty ftiffas well as tough concrete,and that each Ca- 
vern, Bubble, or Cell, is diftin@tly feparate from any of the reft, without 
any kind of hole in the encompatfiing films, fo that I could no more blow 
through a piece of this kinde of fubftance,then I could through a piece of 
Cork, or the found pith of an Elder. | 3 
But though I could not with myAGcrofcope, nor with my breath, nor 
any other way I have yet try'd, difcover a paflage out of one of thofe 
Cavities into another, yet I cannot thence conclude, that therefore there 
are none fuch, by which the Succws zutritius,or appropriate juices of Ve- 
getables, may pafs through them; for, in feveral of thofe Vegetables, 
whil'ft green, I have with my Aé4cro(cope, plainly enough difcover'd thefe 
Cells or Poles fill’d with juices, and by degrees fweating them out: asI 
have alfo obferved in green Wood all thofe long Adcrofcopical pores 
which appear in Charcoal perfectly empty of any thing but Air. 
. Now, though I have with great diligence endeavoured to find whe- 
ther there be any fuch thing in thofe Adicrofcopical pores of Wood or 
Piths, as the Valves inthe heart,veins,and other paflages of Animals,that 
open ‘and give paflage to the contain‘d fluid juices one way, and fhut 
ves,and impede the paflage of fuch liquors back again,yet have I 
notihitherto been able to fay any thing pofitive in it; though,me thinks, 
it feems very probable,that Nature has in thefe paflages,as well as in thofe 
of Animal bodies,very many appropriated Inftruments and contrivances, 
whereby to bring her defigns and end to pafs,which ‘tis not improbable, 
but that fome diligent Obferver, if help’d with better Aticrofcopes, may

And is may be fo, feems'with great probability to be arg 
from the ftrange Phenomena of ki Sed seen ee Nature feems 
to perform feveral Animal actions with the fame schematifm or Orginiza-_
