I marked in the fame manner as the Vine 

 at the proper fcafons, young Honeyfiickle 

 fhoots, young Afparagus* and youn"- Sun- 

 flowers i and I found in them all a gradual 

 fcale of unequal extcnfions, thofe parts ex- 

 tending moft which were tendcreft. The 

 white part of the Afparagus, 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 

 grcateft 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 dis- 

 tance; the greatcft diftenfion of the Sun- 

 flower was from % inch, to four inches dif- 

 tahce. 



From thefc Experiments, it is evident, 

 that the growth of a young bud to a fhoot 

 confifts in the gradual dilatation and exten- 

 sion of every part ; the knots of a fhoot 

 being very near each other in the bud, as 

 may plainly and diftin&ly be fecn in the flit 

 bud of the Vine and Fig tree ; but by this 

 gradual diftcntion of every part, they are ex-
