274 The Colours Lea. V. 
6. §. I fay therefore, that in Blews, Purples and efpecially Reds, 
the predominant Principles being Sulphur and Acid, the Oy! either ab- 
{tracts the Sulphur of it fel, or at leaft, unlocks it from the Acid Parts 
whereby both of them are beftowed feperately to their like parts in 
the Oyls upon which their difanion the Colvur vanifhes: that de- 
pending, not upon either of them alone, which of themfelves are Co- 
fourlefs, but upon both united together. 
7. §- Onthe contrary, a Greez Colour not depending on a pre- 
dominant Acid, but an Alkaly, or fome Saline Principle different from an 
Acid this will not fo edfiely be imbibed {eparately,into the Pores of the 
oy!, but only by mediation of their Sulphur. Sothat being both imbi- 
bed without any difanion, they ftill retein the fame greex Colour they 
had before in the Plant. 
8. §. Hence alfo it is, that red Rofés being dryed and infafed {ome 
time in Oyl of Avife Seeds, a more potent Menfiruum than Common Oy! 5 
they wholly lofe their.own Colour, and turn white; the Oyl remain- 
ing Limpid, as at the firft, That isthe Sulphur or that part of it on 
which cheifly the Red depended, is abforbed feparately by the Oy, and | 
fo the Colour vanithes. 
9: §. A SECOND Menftruum 1 made ufe of, was Water. And Firft, 
Alkanet Root, which immediately tin@ures Oy with a deeper Red, 
will not colour Water in the leaft, 
To. §. Next it isobfervable, That Water will take all the Colours 
of Plants in Infuffon except a Green. So that as no Plant will by In- 
fufion give a perfect Blew to ols fo their is none, that I know of, 
which, by Infuffor will give a perfedt Green to Water. 
: TI. §. But although the Green Leavs will not give their viffble 
Colour, by Infufion in Water 5 yet they will give moft other Colours, as 
well as the Flowers themfelves. So the Green Leavs Of Cinguefoyl, 
give a Tindfure no higher than to refemble Rhenifh wine; thole of 
Fyffop, Canary; of Strawberrey, Malaga; of Mint, Mufcadine, of 
Wood-Sorrel, Water and fome drops of Clarets of Blood-wort, Water 
and a dah of Claret 5 and thofe of Bawm make a Tiwfure near as red 
as ordinary Claret alone. All Aromatick hot Plants, give a yellow-red 
Tintfure, or colorens ex luteo rubrum. All Plants with a yellow Flower 
give either a pale citrine or sellowifh Tiniture sand the like. Yet all 
give not their Tixéwre in the fame {pace of times fome requiring a 
fortnight, others a week, others five, three or two days, and fome 
but one, or halfaday. From hence it appears, that the Colours of 
moft Flowers are begun in the Leaus only Gree» being therein the 
predominant Colour, aga veil {pred over them, conceils all the reft. 
But pafling on into the Flower, where the Aer-Veffels, as is aforelaid, 
under the dominion of the Lympheduéiss they thew themflves 
iftinly. 
12. §. A THIRD and the lat Menftrunm made ufe of, was spirit 
of Wine. And here itis to be remarqued; That as Oy/ rarely takes a 
Red, there being bat one known Inflance of it 5 nor Water, a Green: 
So neither Spirit of Wine, a Blew. 1 have tryed with feveral blew 
Flowers, as of Lark-heel, Violet, Mallows, Burrage, and others, where- 
of it will not take the leat Tindure. 
13. §. Again though no Blew Flowers, that I know of, will givea 
Blew Tindlure to Spirit of Wine: yet having been for fome days infufed
