Plagiarifm, fince the A6ls of that Society are 

 defign'd for Publick Ufe 5 his Theme was 

 indeed at firft concerning Water, but his 

 Conclufions are of a mix'd nature , and 

 may not improperly be brought under this 

 Head. 



In Plants of the farne kind, the lefs they ohfetv, 

 are in Bulk, the f?naller the Quantity of the 

 Fluid Mafs in vohich they are Jet is drawn ofx^ 

 the Difpendium of it^ vohere the Mafs is of 

 equal Thicknefs^ bei?i^ pretty nearly propor- 

 tioned to the Bulk of the Plant. Thus that 

 in the Glafs marked A, p. 120, the which 

 weighed only 27 grains, drew oiF but 2558 

 grains of the Fluid ^ and that in B, which 

 weighed only 28 -^, took up but 3004 grains -^ 

 whereas that in H, which weighed 127 

 grains, fpent 141 90 grains of the Liquid 

 Mafs. 



The Water feems to afcend up the Tejfels 

 of Plants in much the fame manner as up a 

 Filter 5 and 'tis no great wonder that a larger 

 Filter fhould draw off more Water than a 

 leffer 3 or that a Plant that has ?/iore and 

 larger Veffels fhould take up a greater Ihare 

 of the Fluid in which 'tis fet, than one that 

 has fencer and jmaller ones can. Nor do I 

 note this as a thing very confiderable in itfelf, 

 but chiefly in regard to what I am about .to 

 offer beneath 5 and that it may be feen that 

 in my other Collations of Things^ I made due 

 Allowance for this Difference.
