Mutability.
Infuse a few shavings of logwood in common water, and when the liquid is sufficiently red pour it into a bottle. Then take three drinking glasses and rinse one of them with strong vinegar; throw into the second a small quantity of pounded alum, which will not be observed if the glass has been washed, and leave the third without any preparation. If the red liquor in the bottle be poured into the first glass, it will appear of a straw color; if the second it will pass gradually from a bluish gray to black, when stirred with a key or any piece of iron which has been previously dipped in strong vinegar. In the third glass the red liquor will assume a violet tint.
