Report on PARAGUAYAN JABORANDI. 
HIS specimen is undoubtedly true Jaborandi, but it is far inferior 
to the Pernambuco Jaborandi, e its physiological action is much less, 
weaker as a sweater than the alkaloid obtained from the Pernambuco 
Mr. А. W. Gerrard, F.C.S., made the pharmacentical examination, 
над І "aig his repo 
estimations were made E - alkaloid i in the leaves, pa this, 
` fmi into nitrate, gave a me *12 per cent. This is 
very small compared with that of м Jaborandis. The nitrate ‘of the 
alkaloid formed a moist semi-crystalline mass, slightly deliquescent, thus 
difering from the Pilocarpine of ordinary Jaborandi. 
“ The leaves are us RE rich in essential oil. This at present 
has no — al value 
t 
diaphoretie; and our physiological investigation suggests that the 
alkaloid derived from the Paraguayan specimen contains but little of the 
diaphoretic alkaloid. 
Mr. S. Stonham, resident house physician e vides d College, 
made the physiological investigation. He experi 
well as on other persons. He employed an edens of the leaves, ‘the 
liquid extract, and the alkaloid. 
The Paraguayan specimen, like ordinary Jaborandi, causes sweating, 
salivation, and lachrymation, the salivation in every instance being in 
of the sweating. 
Mr. Stonham made three observations with an infusion, using 90, 90, 
me^ 120 grains of the leaf respectively ; two observations with liquid 
xtract, using 5ij and 5iij respectively ; - four observations with. the 
alkaloid, using 4, 4, } of a grain, and 1 D respectively. The 
alkaloid was administered us эрлик < to 90 grains of the
