Mercury-^ which appears to pafi 

 quite through them3 in that by a 

 very good Glafs it is vifible in their 

 Orifices at both ends ^ and with-

 Coal alone, is a I lb manifcfr. 



Upon fartht^r Enquiryg I like- 

 wiie find, that the For ^s of the Lr- 

 gnoi^sBGclym. th^Jrup^k. of Plants^ 

 which at firft we only fuppofed3by 

 the help of good Glailes are very 

 fairly vifible «> each Fibre being 

 perforated by go^ 50^ loOo or hun- 

 dreds of Pores. Or what I think 

 is the trueft notion of them:, that 

 each Fibre^ though it feem to the 

 bare eye to be but one^ yet is in- 

 deed a great number of Fibres to- 

 gether 5 every Pore being not 

 meerly a fpace betwixt the feveral 

 pores of the Wood^ but the Con- 

 cave of a Fiber; So that if it be 

 asked, what all that part of a Ve- 

 getable ^ either Plant or Tree^ 

 which is properly caird the w^oody 



part^
