The Quillai or Cully of the Chilians. Its

bark is called soap-bark, and is rough and dark-colored

externally, but internally consists of numerous regular whitish or

yellowish layers, and contains a large quantity of carbonate of

lime and other mineral matters. It is also rich in _saponine_, and

is used for washing clothes; 2 ounces of the bark is sufficient to

wash a dress. It also removes all spots or stains, and imparts a

fine luster to wool; when powdered and rubbed between the hands in

water, it makes a foam like soap. It is to be found in commerce.
