Printed for Sherwood, Gilbert, And Piper,

Take fifty pounds of good indigo in fine powder; fifty pounds of fresh slacked stone lime; one hundred pounds of sulphate of iron; and five pounds or more of pearl-ashes. Stir often for three or four days till there is a fine copper-colour scum on the top of the liquor in the vat. The vat is of course to be set with water in the usual way.

The substance of this form is from M'Kernan; we cannot, however, avoid thinking, that his directions for this vat are very vague.
