lime-water. With these tests I ohtained the fol-
lowing results:—1st, Tinctured with brandy it
became a deep black, and deposited black fseculae
in considerable quantities, like faeces of ink; the
discoloured liquid tasted like ink diluted with
water, allowing for the vinous taste of the brandy.
2nd. Tinctured with the watery infusion of green
tea, it gave the same result, but much more perfect
in every respect. 3rd. The animal and vegetable
alkalies formed a blue precipitate, leaving a red
ferruginous scum on the surface of the remaining
liquid; when filtered and evaporated in the sun,
the precipitate remained of a reddish colour,
but without taste or flavour. 4th. A piece of
bright iron immersed, formed a red ferruginous
precipitate, but without discovering the smallest
particle of copper to the taste or smell. 5th. So-
lution of silver formed a scarcely-perceptible milky
cloud, which soon turned to a reddish brown.
6th. Aqua-fortis occasioned no effervescence or
precipitate, but formed a slight brownish cloud.
7th. Powdered sal-ammoniac produced no sensible
change. 8th. Lime-water formed a red precipi-
tate in large quantities. 9th. Milk curdled slowly
in a slight degree with about one-sixth part its
quantity of the mineral water, but the milk was not
pure. 10th. A red rose immersed preserved its
vivid colour. 11th. Evaporated by fire with a
piece of bright silver in it, the silver shewed no
lime-water. With these tests I ohtained the fol-
