Veratrum  Viride.  By  John  Uri  Lloyd.  Reprint  from  Western  Druggist, 
October,  1897. 
Like  the  preceding,  this  is  an  interesting  study  of  an  important  drug.  The 
section  on  the  chemical  composition  is  especially  complete,  and,  although  the 
author  has  summed  up  a  mass  of  literature  on  the  subject,  he  suggests  that  an 
additional  investigation  should  be  made,  in  order  to  more  clearly  define  the 
chemical  characters.
