Or Cappagh Brown Is Likewise A Colour Peculiar To Oil It Is A


species of bog-earth or peat, mixed with manganese in various

proportions, and found on the estate of Lord Audley at Cappagh, near

Cork. The specimens in which the peat earth most abounds are of light

weight, friable texture, and dark colour; while those which contain more

of the metal are heavy and paler.

As pigments, the peaty Cappah brown is the most transparent and rich in

second as a superior umber. The two extreme kinds should be

distinguished as light and deep Cappah browns; the former excellent for

place while drying in oil by fixing the oil, like the driers of lead,
