X. Tbe Conclufion of Pr« Defagulier’j Account 
of Mr. Hales’j Vegetahk Statkks. 
CHAP. VII. Of Vegetation. 
UR Author in this Chapter applies his feveral 
Experiments, and Conclufions drawn from 
them, to Vegetation ; and fliews chiefly the follow- 
ing Things, viz. That Vegetables are compos’d of 
i)ulphur, volatile Salt, Water, Earth and Air. 
That in Nutrition the Sum of the attrading Powers 
of thole Subflances is fuperior to the Sum of the 
repellent ; and as the watry Vehicle flies off, the Parts 
harden. 
That Oil, which is made up of Sulphur and Air, 
abounds in Seeds for their better prefervation. 
That in cold Countries, where thofe Principles are 
not fo firmly united, fmall Wines, fuch as Rhenijhy 
moft eafily yield their Tartar fwhich by Experiments 
appears to contain Oil and Air;) but generous Wines, 
fuch as Madsra^ having thofe Principles more firmly 
united, will bear a great degree of Heat before they 
part with them. 
That the ufe of the Leaves of Trees is to bring 
up Nourilhment wfithin reach of the Attradfion of 
the Fruit, to carry off th6 redundant watry Fluid ; 
to imbibe Rains and Dews which are impregnated 
with Salt'' and Sulphur ; as likevvife to imbTbe 
• Air, and to be of the fame ufe to Plants as the Lungs 
are to Animals. 
That Plants which are overfliaded, or too replete 
with Moiflure , cannot fo well imbibe Air : There- 
fore, tho^ they will llioot out fait, and have much 
Wood, they w'iil be more barren in proportion.
