for, when we refer to this department, we shall find very few plants which are either now, or ever have been, cultivated for this purpose, although it is well known that so many contain this principle. I have inserted the following, as being known to contain the different colours mentioned; but there are many other plants equally productive of this principle that remain quite unnoticed at present. 539. ACANTHUS mollis. BEAR'S-BREECH.--This gives a fine yellow, which was in use among the ancients. 540. ACTAEA spicata. BANEBERRY.--The juice of the berries affords a deep black, and is fixed with alum. 541. ANCHUSA officinalis. YELLOW ANCHUSA, or BLUE-FLOWERED BUGLOSS.--The juice of the corolla gives out to acids a beautiful green. 542. ANTHEMIS tinctoria.--The flowers afford a shining yellow. 543. ANTHYLLIS vulneraria. KIDNEY-VETCH.--The whole plant gives out a yellow, which is in use for colouring the garments of the country- people.--Linn. 544. ARBUTUS uva-ursi. BEAR'S-BERRY.--The leaves boiled in an acid will dye a brown. 545. ASPERULA tinctoria. WOODROOF.--The roots give a red similar to madder. 546. ANEMONE Pulsatilla.

DWARF-BIRCH.--The leaves, a yellow. 553. BETULA Alnus. ALDER.--The bark affords a brown colour; which with the addition of copperas becomes black. 554. CALENDULA officinalis. COMMON MARIGOLD.--The radius of the corolla, if bruised, affords a fine orange. The corolla dried and reduced to powder will also afford a yellow pigment. 555. CALTHA palustris. MARSH-MARIGOLD.--The juice of the corolla, with alum, gives a yellow. 556. CAMPANULA rotundifolia. ROUND-LEAVED BELL-FLOWER.--A blue pigment is made from the corolla; with the addition of alum it produces a green colour. 557. CARPINUS Betulus. HORNBEAM.--The bark, a yellow. 558. CHAEROPHYLLUM sylvestre. COW-PARSLEY.--The umbels produce a yellow colour, and the juice of the other parts of the plant a beautiful green. 559. CARTHAMUS tinctorius. SAFFLOWER.--The radius of the corolla, prepared with an acid, affords a fine rose-coloured tint. 560. CENTAUREA Cyanus. BLUE-BOTTLE.--The juice of the corolla gives out a fine blue colour. 561.
