Experiment XLI. 
Augufi 13- At noon I took a large branch 
of an Apple-tree, (Fig. 22.) and cemented 
up the tranfverfe cut, at the great end x, and 
tyed a wet bladder over it : I then cut off 
the main top branch at b 5 where it was t 
inch diameter, and fet it thus inverted into 
the bottle of water b. 
In three days and two nights it imbibed 
and perfpired 4 pounds -j- 2 ounces 1- of 
water, and the leaves continued green 5 the 
leaves of a bough cut off the fame tree at 
the fame time with this, and not fct in ' 
water, had been withered 40 hours before. 
This, as well as the great quantities imbibed 
and perfpired, fhews, that the water was 
drawn from b moft freely to e,f,gy h, and 
from thence down their refpeftive branches^ 
and fo perfpired off by the leaves. 
This Experiment may ferve to explain the 
reafon, why the branch b, ( Fig. 23. ) which 
grows out of the root e x, thrives very well, 
notwith^
