Ber The Colours Lea. vV. 
__5: $ Spirit of Harts Horn droped upon a Tinure of the Flavor 
of Lark-heel and Borage turn them to a verdegreefe Green, 
6. §. Spirit of Harts Horn droped on moft green Leavs doth not 
change themat all. The like Effects have Ag. Calcis, and spirit of 
S. Armoniac. 
7. $. Thele Experiments feemto confirm, That it is fome Alkaline 
or other like Salt in the Aer, which is predominant in the production 
of Green in the Leavs of Plants, 
8. $. Salt of Tartar droped on the white Flowers of Deifj, chang- 
eth them into a light Green. Which as it further confirms the aforefaid 
Pofition ; fo likewife ues, That Whitenef in Flowers, is not always 
from the defect of Tindure: but that there may be White, as well as 
Yellow, Green, Red or Blew Tindures. 
2. $... Spirit of Sulphur droped on the green Leavs of Adonis Flower, 
Everlasting Peafe, and Holy Oak, turns them all Tellow. 
To. $. Spirit of Sulphur on a Tinéture of Saffron changethit not. 
II. $. Spirit of Sulphur on the Yelow Flower of Crowfoot alters 
them not. Neither are they changed by the Afifon of Alkalier. 
12. $. So that it feemeth, that in all Yellows, the Sulphureous Acid 
and Alkaline Parts are all more equal, 
13. $. Spirit of sulphur on a Tindure of Violets turns it from Blew 
toa true Lacke, or midle Crimfou, 
14. $. Spirit of Sulphur upon a Tinéture of Clove-Fuly-Flowers makes 
a bright blood Red. Into the like Colour, it hightens a Tinéture of Red 
Rafer 
15. §. Sothat as Alkalys, or other Analogous Salts, are predomi- 
ant in Greens, fo Acids in Reds, efpecially in the brighter Reds, in 
the Leavs and Flowers of Plants. Hence it is, that Spirit of Nitre 
droped upon the Blew Flower of Ladies Looking-Glafs, Larkspur, Bo 
rage, turns them all Red, fè. into the Red of Common Lycknis. But 
(which is particularly to be noted) being droped on the fiid Red 
Flowers of Lychnis, alters them little or nothing: becaufe, that very 
Colour is therein produced by a copious admixture of the like Prin- 
ciple. 
A $. The Summ therefore of what hath now been faid, of the 
aufés of Vegetable Colours, isthis: That while their Sulphur and Saline 
Principles, only fwim together, and are not as yet united into one Pre- 
cipitate, no Colour refùlts from them, but the Contents are rather 
Limpid 5 as ufially in the Rost, and many other Parenchymons 
Parts, 
17. $. When they are united, and the Alkaline axe predominant, 
they produce a Green, 
18. $. When the Sulphur and the Alkaline are more equal, they 
produce a Tanny. i 
19. $. When the Sulphur, Acid and Alkaline, there a Yellow. 
20. $. When the Sulphur predominant, and the Acid and Alkaline 
equal, there a Blew. 
21. $. When the Sulphur and Acid are predominant to the Alkaline, 
then a Purple. 
22. $. When the Sulphur predominant to the Alkaline and the Acid 
tothem both, a Scarlet,
