Black Specks; and that this Juice by a drop of a ſtrong Lixivium, was immediately turn'd into a Greeniſh Colour deep enough, by as much Urinous Spirit into a Colour much of Kin to the former, though ſomewhat differing, and fainter; and by a drop of Spirit of Salt into a fine and lightſome Red: where as the Red Berry being in like manner rubb'd upon Paper, left on it a Red Colour, which was very little alter'd by the Acid Spirit newly nam'd, and by the Urinous and Lixiviate Salts receiv'd changes of Colour differing from thoſe that had been juſt before produc'd in the dark Juice of the Ripe Blackberry.
I remember alſo, that though the Infuſion of Damask-Roſes would as well, though not ſo much, as that of Red, be heightned by Acid Spirits to an intenſe degree of Redneſs, and by Lixiviate Salts be brought to a Darkiſh Green; yet having for Trials ſake taken a Roſe, whoſe Leaves, which were large and numerous, like thoſe of a Province Roſe, were perfectly Yellow, though in a Solution of Salt of Tartar, they afforded a Green Blewiſh Tincture, yet I did not by an Acid Liquor obtain a Red one; all that the Saline Spirit I imploy'd, perform'd, being (if I much miſremember
not) to Dilute Somewhat the Yellowneſs of the Leaves. I would alſo have tried the Tincture of Yellow Violets, but could procure none. And if I were in thoſe Iſlands of Banda, which are made Famous as well as Rich, by being the almoſt only places, where Cloves will proſper, I ſhould think it worth my Curioſity to try, what Operation the three differing Kinds of Salts, I have ſo often mention'd, would have upon the Juice of this Spice, (expreſs'd at the ſeveral Seaſons of it) as it grows upon the Tree. Since good Authors inform us, (of what is remarkable) that theſe whether Fruits, or Rudiments of Fruits, are at firſt White, afterward Green, and then Reddiſh, before they be beaten off the Tree, after which being Dry'd before they are put up, they grow Blackiſh as we ſee them. And one of the recenteſt Herbariſts informs us, that the Flower grows upon the top of the Clove it ſelf, conſiſting of four ſmall Leaves, like a Cherry Bloſſom, but of an excellent Blew. But (Pyrophilus) to return to our own Obſervations, I ſhall add, that I the rather chooſe, to mention to you an Example drawn from Roſes, becauſe that though I am apt to think, as I elſewhere advertiſe, that ſomething may be gueſs'd at about
ſome of the Qualities of the Juices of Vegetables, by the Reſemblance or Diſparity that we meet with in the Changes made of their Colours, by the Operation of the ſame kinds of Salts; yet that thoſe Conjectures ſhould be very warily made, may appear among other things, by the Inſtance I have choſen to give in Roſes. For though, (as I formerly told you) the Dry'd Leaves, both of the Damask, and of Red ones, give a Red Tincture to Water ſharpen'd with Acid Salts, yet the one ſort of Leaves is known to have a Purgative faculty,[a]20] and the other are often, and divers ways, imploy'd for Binding.
And I alſo chooſe (Pyrophilus) to ſubjoyn this twenty ninth Experiment to thoſe that precede it, about the change of the Colours of Vegetables by Salts, for theſe two reaſons: The firſt, that you may not eaſily entertain Suſpitions, if in the Trials of an Experiment of ſome of the Kinds formerly mention'd, you ſhould meet with an Event ſomewhat differing from what my Relations may have made you expect. And the ſecond, That you may hereby be invited to diſcern, that it may not be amiſs to take notice of the particular Seaſons wherein you gather the Vegetables which
in Nicer Experiments you make uſe of. For, it I were not hindred both by haſte and ſome juſtifiable Conſiderations, I could perhaps add conſiderable Inſtances, to thoſe lately deliver'd, for the making out of this Obſervation; but for certain reaſons I ſhall at preſent ſubſtitute a remarkable paſſage to be met with in that Laborious Herbariſt Mr. Parkinſon, where treating of the Virtues of the (already divers times mention'd) Buckthorn Berries, he ſubjoyns the following account of ſeveral Pigments that are made of them, not only according to the ſeveral ways of Handling them, but according to the differing Seaſons of Maturity, at which they are Gather'd; Of theſe Berries, (ſays he) are made three ſeveral ſorts of Colours as they ſhall be gather'd, that is, being gather'd while they are Green, and kept Dry, are call'd Sapberries, which being ſteep'd into ſome Allom-water, or freſh bruis'd into Allom-water, they give a reaſonable fair Yellow Colour which Painters uſe for their Work, and Book-binders to Colour the edges of Books, and Leather-dreſſers to Colour Leather, as they uſe alſo to make a Green Colour, call'd Sap-green, taken from the Berries when they are Black, being bruis'd and put into a Braſs or Copper Kettle or Pan, and there ſuffer'd to abide three or four
Days, or a little heated upon the Fire, and ſome beaten Allom put unto them, and afterwards preſs'd forth, the Juice or Liquor is uſually put in great Bladders tied with ſtrong thred at the Head and hung up untill it be Dry, which is diſſolv'd in Water or Wine, but Sack (he affirms) is the beſt to preſerve the Colour from Starving, (as they call it) that is, from Decaying, and make it hold freſh the longer. The third Colour (where of none (ſays he) that I can find have made mention but only Tragus) is a Purpliſh Colour, which is made of the Berries ſuffer'd to grow upon the Buſhes untill the middle or end of November, that they are ready to drop from the Trees.
And, I remember (Pyrophilus) that I try'd, with a ſucceſs that pleas'd me well enough, to make ſuch a kind of Pigment, as Painters call Sap-green, by a way not unlike that, deliver'd here by our Author, but I cannot now find any thing relating to that matter among my looſe Papers. And my Trials were made ſo many years ago, that I dare not truſt my Memory for Circumſtances, but will rather tell you, that in a noted Colour-ſhop, I brought them by Queſtions to confeſs to me, that they made their Sap-green much after the ways by our Botaniſt here mention'd. And on this occaſion
I ſhall add an Obſervation, which though it does not ſtrictly belong to this place, may well enough be mention'd here, namely, that I find by an account given us by the Learned Cluſius, of Alaternus, that ev'n the Groſſer Parts of the ſame Plant, are ſome of them one Colour, and ſome another; For ſpeaking of that Plant, he tells us, that the Portugalls uſe the Bark to Dye their Nets into a Red Colour, and with the Chips of the Wood, which are Whitiſh, they Dye a Blackiſh Blew.
