of the Tabajheer. \ 2 yf 
The two middle joints were of a pure white colour within, 
and lined with a thin film ; it was in thefe chiefly the Ta- 
bafheer was found. The others, particularly the two upper 
joints, were difcoloured within, and in fome parts of the 
cavity was found a blackifh fubftance in grains or in powder 
adhering to the Tides, the film being there obliterated. In two 
or three of the joints, a fmall round hole was found at top and 
bottom, which feemed to have been" perforated by fome 
in fed. 
In the month of July, forty-three green bamboos, each 
confiding of five or fix joints, were brought from the hills 
fifty miles diftant from hence. Six, appearing to contain more 
Tabafheer than the others, were fet apart; the remaining 
thirty-feven were fplit and examined in the manner before- 
mentioned. The refult was as follows. 
In nine out of the thirty-feven there were no vefliges of 
Tabafheer. In twenty-eight fome were found in one, two, or 
three joints of each ; but never in more than three joints of 
the fame bamboo. The quantify varied, but in all was incon- 
fiderable ; and the empty joints were fometimes contiguous, 
fometimes interrupted, indifferently. 
The drug confifts of very diffimilar particles at firfl when 
taken rrom the bamboo, as will appear in looking into the 
fmall fpecimen, -N° i.; which, having collected myfelf, I am 
certain has undergone no adulteration. 
The whiter, fmooth, harder particles, when not loofe toge- 
ther with the others in the cavity, were moftly found adher- 
ing to the feptum that divides the joints, and to the fides con- 
tiguous ; but never to the fides about the middle of the joints ; 
and it may be remarked, that, inftead of being chiefly found at 
the lower extremity of the joint, as might be expeded from
