dye  is  derived  from  alizarine,  but  not  otherwise.  The  question  under 
consideration  in  the  above  decisions  was  whether  or  not  certain  dyes 
were  derived  from  alizarine.  These  precedents  must  undoubtedly 
be  taken  into  consideration  in  connection  with  the  recently  enacted 
pure  food  and  drug  law,  but  the  aims  and  objects  of  the  latter  are 
entirely  different  from  those  of  the  tariff  law. 
The  meaning  of  the  term  "  derivative,"  as  used  in  the  act,  has 
been  called  into  question  because  (para)  acetphenetidin  is  classed  as 
a  derivative  of  acetanilide.  There  is  no  question  but  that  (para) 
acetphenetidine  is  a  derivative  of  acetanilide,  both  chemically  and 
physiologically,  and  resembles  it  in  its  tendency  to  habit  formation, 
physiological  action,  and  physical  properties.  Furthermore,  Treas- 
ury decision  13,270  construes  this  chemical  as  an  alcoholic  medicinal 
preparation.  The  exact  status  of  this  product  under  the  law  there- 
fore appears  to  be  in  a  somewhat  unsettled  condition  at  present.
