The leaves were boiled in several liters of water, but 
only half of the resulting infusion, or one liter, was used 
on this occasion. This simmering infusion was added to 
the cold drink previously prepared, and the sap and small 
particles from the shredded and pounded bark completed 
the luke-warm mixture. 
The two bottles of brawn left from another occasion 
could have been taken alone, but Chindoy advised that ‘‘it 
is better to refine the biawit’’. He said the chagruponga 
leaves had to be included, ‘‘in order to see pictures”’, 
for the biava bark alone is not hallucinogenic. The re- 
maining liter of cagruponga infusion, the squeezed bark 
scrapings, the wood of the six sections already scraped, 
as well as the two untouched sections, were saved to 
prepare more (iawii at a later date. If all these materials 
are, in fact, used in making the next brawii, its prepara- 
tion will conform neither to the stated ideal, nor to the 
procedure just described. Presumably, some (rawii left 
over from the present batch would serve as the basis for 
the next. 
Although women are never allowed in or near the hut, 
once the preparation is complete, the draat can be taken 
to the house, for ‘‘the women can no longer harm it’’.

It was then about 8:30 P.M., and Chindoy’s wife and 
the three visitors had gone to bed on reed mats on the 
floor in the main room. The medicine-man arranged his 
blankets on the raised wooden bed, and I slept on the 
floor ona mat. It is common for friends of the medicine- 
man to spend the night at his house at such opportunities 
to take biavii, and I was not in an awkward atmosphere. 
The drink was to be taken around midnight. 
The stated purpose of taking biawi on this occasion 
was twofold. First: a young couple with an ailing infant
