 earth when the tree was planted, and the 

 weight thereof when it was taken up. 

 But fome difference muft be reasonably 

 expe6led ; for there is a fait found in foot, 

 and confequently part of its weight Is car- 

 ried off by fmoke, whofe heavieft parts 

 form that body, and the lighteft are mere 

 watery ; fo that, after the plant is burnt 

 and confumed in manner aforefaid, there 

 are no marks of earth remainiiig:.
