thol,  etc.,  contained  in  the  powder,  if  present,  were  far  below  the 
quantities  indicated  by  the  formula.    The  presence  of  glycerin  could 
not  be  demonstrated,  and  if  present  the  amount  must  be  very  small. 
Our  chemist  reports  : — 
The  result  of  analysis  shows  that  different  samples  differ  slightly 
in  composition,  but  that  the  following  indicates  the  average  compo- 
sition of  the  product : — 
The  undetermined  portion  consists  of  salicylic  acid,  carbolic 
acid,  menthol  and  eucalyptol;  possibly  other  antiseptic  agents  may 
be  present  in  very  minute  quantities. 
From  the  above  findings  we  conclude  that  Tyree's  antiseptic 
powder  is  a  mixture  of  boric  acid  and  dried  zinc  sulphate  and  anti- 
septic bodies,  such  as  menthol,  salicylic  acid  and  carbolic  acid,  euca- 
lyptol, etc.  From  this  it  can  be  readily  seen  that  the  label  which 
is  supposed  to  set  forth  the  composition  of  Tyree's  antiseptic  pow- 
der is  not  in  accord  with  the  facts.  The  powder  does  not  contain 
either  borate  of  sodium  or  alum,  and  the  presence  of  glycerin  could 
not  be  established.  The  antiseptic  agents,  exclusive  of  the  boric 
acid,  are  present  only  in  small  amounts. 
The  report  of  another  analyst  concludes  as  follows : 
It  evidently  contains  less  than  the  amount  stated  of  the  principles 
of  thyme,  eucalyptus,  wintergreen  and  mint.  It  also  contains  a  very 
small  amount  indeed  of  carbolic  acid,  much  less  than  that  stated. 
We  have  been  unable  to  identify  certainly  the  presence  of  glycerin, 
and  it  is  doubtful  if  it  be  present. 
From  the  result  of  the  analysis  we  feel  confident  that  the  prepara- 
tion is  to  all  intents  and  purposes  a  mixture  of  boric  acid  and  sul- 
phate of  zinc. 
The  carbolic  acid,  thyme,  eucalyptus,  wintergreen,  etc.,  if  present, 
are  present  only  in  sufficient  amount  to  give  the  compound  a  satis- 
factory odor. 
In  view  of  the  fact  that  J.  S.  Tyree  has  given  wide  publicity  to  a 
formula  which  the  preceding  report  has  shown  to  be  a  deliberate 
misrepresentation  of  fact,  it  is  recommended  that  the  article  be 
refused  recognition  by  the  Council  on  Pharmacy  and  Chemistry,  and
