pure Air and Water , till thefe be concreted into pecuHar 
i'altsby more curious Strainers, and by morefubtil Boylers 
than Art hath hitherto devifed. And with no lefs probability 
Mineral Waceis may acquire their proper Salts in their fub- 
terraneouspaflfages by their Strainers and Conveyances, by 
the various Temper they meet with , and by their dafh- 
ts , and following changes of contexture. But this I leave 
to further inquiry. 
And this was my Ayme in your Trad 43, p. 8555 where 
byaflight andcurfory allufion I compared the Motion of Sap 
in Vegetables to the defcent of Liquors in an Alcmbick. I 
had no thought of fquaring the comparifonto agree in all cir- 
cumftances. And here alfo I pretend to very little more than 
allufions all along. It requires deeper work , a larger compa% 
and a clofer attention to eftablifli a General Theory upon the In- 
trigues of Vegetation , and of all Saline Operations: The 
very Air may (for ought I know) afford ftore and variety 
of Salt to dafli the Foundations of my Overtures, at leaft as 
far as pertains to Vegetables. And the Mineral Salts have 
their receffes deeper, than I can dive, and their aftivitics are 
fwifter, than Ihaveskil or leifore to trace. 
Neither had I any pliancy, that the Sap in Winter 
defcended to the Root, fincelfaw an Aple*tree:> that yiel- 
ded 4 or 5 Hog/heads of ftrong Cider yearly 5 and a Pear-tree, 
chat yielded more Perry 5 yet both growing on a dx-y ground , 
where they could get no other liquor then what the Clouds and 
the Air afforded.* Yet I conceive, that thefe Trees have 
an intercourfe of peculiar spirits fome way linked together ^ 
aid vigoroufly co-operating 5 from the very Fibers of the tow- 
weft Roots to the Top-leaves. And of this 1 had fome wari- 
rinefs;)When I exprelfed the correfpondence between the Timber 
and Seeds in thefe i^imi'^ mere immediate md peculiar ^
