We have here alfo many inftances of the 
great force of the afcending fap in the vine in 
the bleeding feafon ; as alfo of the Tap’s free- 
ly either afcending or defcending, as it fhall 
happen to be drawn by the perfpiring leaves 5 
and alfo of its ready lateral motion thro’ 
the laterally communicating fap veffels; to- 
gether with many proofs of the great plenty 
of air drawn in and mixed with the fap, and 
incorporated into the fubftanceof vegetables. 
If therefore thefe Experiments and Obfer- 
vations give us any farther infight into the 
nature of plants, they will then doubtlefs be 
of fome.ufe in Agriculture and Gardening, 
either by ferving to rectify fome miftaken 
notions, or by helping farther to explain the 
reafons of many kinds of culture, which 
long repeated experience has found to be 
good; and perhaps by leading us to make fome 
advances therein: But as it requires a long 
feries and great variety of frequently repeat- 
ed Experiments and Obfervations, to make a 
very fmall advance in the knowledge of the 
nature of vegetables; fo proportionably we 
are from thence only to expeft fome gradual 
improvements in the culture of them.
