EXPERIMENT XXI.

BLew Bottle or Corn-weed being Candied preserves its Colour a long time; and when newly press'd the Juice will be Blew; yet Spirit of Salt will turn it Red, and Alkalies, Green; and this being drawn upon a piece of Paper moisten'd with an Acid, it render'd it Red. A Solntion of blew Vitriol in Water, upon an Addition of a Lixiviate Liquor, or an urinous Salt, becomes Yellow: Whence it appears, that Volatile or Alkalizate Salts change not Blew into Green upon the account of an easie Transition from Blew to Green, but upon the Account of the Texture of them.
