the Sap-Veffels alone, are but few, the Root is yet, ratably, fome- 
what large: but where they are numerous, it is never fo, as to its 
Annual Growth, in any proportion to their Number: Becaufe their 
Tindure, which is Alkaline, will go farther in fetting the Parenchy- 
mous Parts: than the Zindure of Thefe, which is Acidulate, will go,
