Cassia Fistula

: ON THE TERTIARY, CITRINE.

is a native vegetal pigment, though it is more commonly employed as a

medicinal drug. It is brought from the East and West Indies in a sort of

cane, in which it is naturally produced. As a pigment it is deep,

transparent, of an imperfect citrine colour, inclining to dark green,

and diffusible in water without grinding, like gamboge and sap green.

Once sparingly used in water as a sort of substitute for bistre, it is

not now to be met with on the palette.
