In the fpring, when the Vines had made 
fhort {hoots, I dipped the points of the pins 
in the paint, and then pricked the young 
fhoot of a Vine, (Fig. 41. ) with the five 
points at once, from t 10 p : \ then took 
off the marking inftrument, and placing the 
loweft point of it in the hole p^ the upper- 
moil mark, I again pricked frefh holes from 
p to /, and then marked the two other 
points i h 5 thus the whole^ihoot was marked 
every i inch, the red paint making every 
point remain vifiblc. 
(Fig. 42.) {hews the true proportion of 
the fame fhoot, when it was full grown, the 
September following 5 where every corre- 
fponding point is noted with the fame let- 
ter. 
The diftance from / to r was not en- 
larged above part of an inch 5 from s to^,

In this Experiment we fee that the firft
