(late the tender extending ftem. 
I marked in the fame manner as the Vine, 
at the proper feafons, young Honeyfuckle 
llioots, young AfparaguSy and young Sun- 
flowers j and I found in them all a gradual 
fcale of unequal extenfions, thofe parts ex- 
tending moft which were tendereft. The 
white part of the AfparaguSy which was un- 
der ground, extended very little in length, 
and accordingly we find the fibres of the 
white part very tough and ftringy : But the 
greateft extenfion of the tender green part, 
which was about 4 inches above the ground 
when I marked it, feparated the marks from 
a quarter of an inch, to twelve inches dif- 
tancej the greateft diftenfion of the Sun- 
flower was from 4 inch, to four inches dif- 
ranee. 
Irom thefe Experiments , it is evident, 
that the growth of a young bud to a fhoot 
confifts in the gradual dilatation and exten- 
iion of every part j the knots of a fhoot 
being very near each other in the bud, as 
may plainly and diftimftly be feen in the flit 
bud of the Vine and Fig tree 5 but by this 
gradual diftention of every part, they are ex-
