Experiment XLI. 



Aug. 13th, 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 

 tied a wet bladder over it : I then cut off the 

 main top branch at b\ where it was -| inch 

 diameter, and fet it thus inverted into the 

 botile of water b. 



In three days and two nights it imbibed 

 and perfpired four pounds two ounces -\- \ 

 of water, and the leaves continued green ; the 

 leaves of a bough cut off the fame tree at 

 the fame time with this, and not fet in 

 water, had been withered forty hours be- 

 fore. This, as well as the great quantities 

 imbibed and perfpired, fhews, that the wa- 

 ter was drawn from b moft freely to e, f y 

 g, l\ and from thence down their refpeclive 

 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 c x y thrives 

 very well, notwithstanding the root c x is 

 here fuppofed to be cut off at c, and to 

 be out of the ground : For by many expe- 

 riments in the fir ft and fecond chapters, it
