14504	Boyle, Robert	Experiments and Considerations Touching Colours (1664)			.txt	text/plain	97341	2648	55	For not remembring at present many of those other Trials, long since made to satisfie my self about Particulars, and not having now the Opportunity to repeat them, I must content my Self to have given you the Hint, and the ways of prosecuting the search your Self; and only declare to you in general, that, As I have made many Trials, unmention'd in this Treatise, whose Events were agreeable to those mention'd in the twenty fifth Experiment, so (to name now no other Instances) what I have try'd with Acid and Sulphureous Salts upon the Pulp of Juniper Berries, rubb'd upon White Paper, inclines me to think, That among that vast Multitude, and strange Variety of Plants that adorn the face of the Earth, perhaps many other Vegetables may be found, on which such _Menstruums_ may not have such Operations, as upon the Juice of Violets, Pease-blossoms, & We have sometimes had the Curiosity to try what Colours Minerals, as Tinglass, Antimony, Spelter, &c. would yield in several _Menstruums_, nor have we forborn to try the Colours of stones, of which that famous one, (which _Helmont_ calls _Paracelsus's Ludus_) though it be digg'd out of the Earth and seem a true stone, has afforded in _Menstruums_ capable to dissolve so solid a stone, sometimes a Yellowish, sometimes a Red solution of both which I can show you.	cache/14504.txt	txt/14504.txt
