a colour composed of a mixture of red and blue.

A beautiful transparent purple for painting may be made by boiling four ounces of ralphed brazil-wood in a pint of stale beer, and half an ounce of logwood, till the liquor is heightened to the colour you desire, which may be known by dipping a piece of paper in it. If you find it too red, add a quarter of an ounce more of logwood, which will render it still deeper; and by this method you may bring it to any degree of purple, by putting in ei- ther more or less logwood to the former composition, and fixing it with alum.
