The Maypures Call It Majepa.

The Spanish missionaries say onotarse, to rub the skin with anato.) called by the Spaniards achote, and by the planters of Cayenne, rocou.

It is the colouring matter extracted from the pulp of the Bixa orellana.* (* The word bixa, adopted by botanists, is derived from the ancient language of Haiti (the island of St. Domingo). Rocou, the term commonly used by the French, is derived from the Brazilian word, urucu.) The Indian women prepare the anato by throwing the seeds of the plant into a tub filled with water. They beat this water for an hour, and then leave it to deposit the colouring fecula, which is of an intense brick-red. After having separated the water, they take out the fecula, dry it between their hands, knead it with oil of turtles' eggs, and form it into round cakes of three or four ounces weight. When turtle oil is wanting, some tribes mix with the anato the fat of the crocodile.

Another pigment, much more valuable, is extracted from a plant of the family of the bignoniae, which M. Bonpland has made known by the name of Bignonia chica. It climbs up and clings to the tallest trees by the aid of tendrils. Its bilabiate flowers are an inch long, of a fine violet colour, and disposed by twos or threes. The bipinnate leaves become reddish in drying. The fruit is a pod, filled with winged seeds, and is two feet long. This plant grows spontaneously, and in great abundance, near Maypures; and in going up the Orinoco, beyond the mouth of the Guaviare, from Santa Barbara to the lofty mountain of Duida, particularly near Esmeralda. We also found it on the banks of the Cassiquiare. The red pigment of chica is not obtained from the fruit, like the onoto, but from the leaves macerated in water. The colouring matter separates in the form of a light powder. It is collected, without being mixed with turtle-oil, into little lumps eight or nine inches long, and from two to three high, rounded at the edges. These lumps, when heated, emit an agreeable smell of benzoin. When the chica is subjected to distillation, it yields no sensible traces of ammonia. It is not, like indigo, a substance combined with azote. It dissolves slightly in sulphuric and muriatic acids, and even in alkalis. Ground with oil, the chica furnishes a red colour that has a tint of lake. Applied to wool, it might be confounded with madder-red. There is no doubt but that the chica, unknown in Europe before our travels, may be employed usefully in the arts. The nations on the Orinoco, by whom this pigment is best prepared, are the Salivas, the Guipunaves,* (* Or Guaypunaves; they call themselves Uipunavi.) the Caveres, and the Piraoas. The processes of infusion and maceration are in general very common among all the nations on the Orinoco. Thus the Maypures carry on a trade of barter with the little loaves of puruma, which is a vegetable fecula, dried in the manner of indigo, and yielding a very permanent yellow colour.
