4. Ditamine. Amorphous alkaloid from the same bark. Both bodies quite 

 new in trade. They represent the effective substances of this drug. 



5. Kamalin crystal, Crystallised body from Kamala, the fibres and glands 

 of the fruit of Rottlera tinctoria. Effective substance of this drug. New in 

 trade. 



6. Muscarin nitricum. Nitrate of the alkaloid contained in the toadstool 

 (Agaricus muscarinus). Muscarin is likewise new in commerce. 



7. Pilocarpin. Alkaloid from the leaves of Policarpus pinnatifolius, Sabor- 

 andi, since a short time only employed in medicine. New in commerce. 



8. Veratric acid, from the. seeds of Sabadilla. 



9. Kosin crystalUsatum. The acting principle of the Koso plant crystallises 

 partly in needles, partly in short thick prisms belonging to the rhombic 

 system. Almost insoluble in water, it is easily dissolved in ether, benzol, 

 sulphide of carbon, and chloroform. Less easily in glacial acetic acid and 

 alcohol.
