(pp31-61) and miscellaneous notes, p13.: From this is prepared an intoxicating drink known to all the natives on the Uaupes by name of Caapi. The lower part of the stem which is, the thickness of the thumb and swollen at the joints is part used. This is beaten in a mortar with the addition of water and a small quantity of the slender root of an apresree (caapi-pinima). The ingredients are then passed through a sieve. Such a qu, antity of water is added to render it drinkable. In this state its colour is a brush- gun and its taste bitter and disagreeable. During their Dabocuris, the young men who figure in the dances drink of the caapi 5 or 6 times during the night from a small, enya, the size of a very small cup, twice filled. In 2 minutes after drinking, or less, its effect begins to be apparent. The Indian turns deadly pale, trembles in every limb and horror is in his aspect; suddenly contrary symptoms succeed- he bursts in, to a perspiration and seems possessed with reckless fury- seizes whatever arms are at hand his murucú, bow and arrows or cutlass and makes to the doorway where he inflicts deadly blows on the ground or doorposts calling out' thus would I do to my enemy (n, aming him by name) where he within my reach'. Those whites who have partaken of the caapi all agree in the account of their sensations under its effects- alterations of cold and heat, of fear and boldness. The light is disturbed and visions appear rapid, ly before their eyes in which everything joyous and magnificent they have heard or said of dreams united. I drank 1 cup of caapi but found taste so unpleasant that I did not venture on a second. Immediately after a woman brought me a larger cup full of, cúsasi of which I was obliged to drink a copious draught.x0Dx0A
