These  results  differ  from  those  obtained  by  Kahn  (Amer.  Jour.

diameters.

comparative  analyses  were  made  : 
Per  Cent. 
(I)  Petroleum  ether  extract,      7 -380

The  ether  extract  contained  an  alkaloid  which  was  soluble  in 
dilute  HC1.  The  microscopical  drawing  will  illustrate  the  crystals 
under  an  amplification  of  325  diam.
