Quatrrizs. Scarcely soluble in cold water—boiling water 
dissolves one thousandth of its weight, becoming sensibly 
acrid—very soluble in ether—more so in alcchol—soluble 
in all vegetable acids, which it saturates, and forms with 
them inerystallizable salts, which, on evaporation, resem- 
ble gum—the sulphate alone affords rudiments of crystals, 
when its acid is in excess—insoluble in alkalies—restores 
the blue of turnsole paper rubified by acids. Liquefies by 
heat of 122°F. resembling wax; on cooling, forms a __ 
translucent mass, resembling somewhat the appearance of 
amber. A dose of 4 of a grain, produces copious alvine 
discharges. If the dose be increased, more or less violent
