9. $. The Marine, is obtained no other way, that I know of but 
from a Solution of the Alkaline, upon its being expofed to the Aer, 
The proceß wherof, I fhall particularly fet down in a following Di: 
Jeourfe. OF thefe Salts, mixed in a certain Proportion, together, and 
alfo Impregnated with fome of the other Active Principles of a Plant, 
and not without an Admixture of (ome Parts from the Aer s Tfappole, 
that which I call the Efential, is produced: of which, I fhall alfo give 
an account in the fame Difconnfe. 
10. $. ALL THE Four salts above mentioned, fem in their Or. 
der, to have a (hare in the Formation of a Leaf, or other Part of a Plant: 
And firft of all, the Marine. For all Generations are made in fome 
Fluid : But in every Fluid there is a perpetual Inteffive Motion of 
Parts, So that the firlt Intention of Nature is, That fome of thofe 
Parts be difpofed to Ref. Now of all the Principles of a Plant, there 
arenone hereunto more difpofed, than their Salts whofe Particles, 
being figu’rd with plain Sides, as often as they touch Side to Side, like 
two Marbles exquifitely polithed, they will adhere together. And the 
Particles of Marine Salt, being Cubick; and fo,with relpeét to their Fja 
gure,of greater Bulk than thofe of. any other Salts they will hereby, be 
moft and firft of all difpofed to Re) 3 and fo become, as it were, the 
Foundation of the following Super(frniture, Be ' 
11. THE Second Intention of Nature is, That the Particles be 
brought to Reff, in a certain Pofition, agreeable to the Figure of the 
Parts which are to be formed. "And therefore in the next place, all 
thofe Parts of a Plant which are truly Lignons, by the Marine Salt, 
made to fhoot out in Length, or into añ innumerable company of (mall Tab, 
Glindrich Fibres: thefe Salts being altogether, fturdy enough to refit 14 52: 
thofe Zpulfés which might incline them to conformto any other Figure, 
12. $. THE next Intention is, That thefe Fibres, at the fame time 
in which they are formed, may likewife receive fach a Pofture as will 
belt anfwer the indented shape of the Leaf. Which Pofture, although 
in the Growth of the Leaf it is much Govern'd by the Aer-Veffels 5 yet 
in the Generation hereof, feems to be firlt determined by the foremen- 
tioned Salts, according to their feveral Angles, whereby they are dif 
ferently applicable one to another, 
13. $. Now all the Sides ofthe Marine Salt, and the Sides and the 
and fome other Bodies, that the Particles of the Alkaline are Square at Tab, 33. 
one End, and Poynted at the other. And thofe ofthe Acid, at both;
