overlooked,  however,  that  many  other  qualifications  are  necessary  in 
addition  to  a  technical  pharmaceutical  training  and  among  these  the 
personal  qualities  are  important.  The  ability  to  assume  command 
and  administer  an  important  office,  becomes  a  prime  requisite  for 
advance. 
The  situation  at  least  is  encouraging  and  with  this  start,  phar- 
macy will  have  every  opportunity  to  develop  in  the  work  of  the  Arrm 
and  the  Navy  during  the  years  ahead  and  we  believe  that  it  can 
thoroughly  demonstrate  its  importance  and  efficiency  and  that  we 
need  never  again  be  ashamed  of  the  place  held  by  pharmacy  in  either 
branch  of  the  service. 
If  these  bills  are  reported  favorably  to  Congress,  ask  your  Con- 
gressman to  give  it  support,  and  a  united  pharmacy  at  this  time  will 
be  necessary  to  the  completion  of  this  programme  and  secure  the 
recognition  of  pharmacy  in  our  military  organizations.

Analysis  of  a  Potter's  Clay  Offered  for  Pharmaceutical 
Purposes. 
Potter's  clay  is  a  very  fine,  dry,  smooth,  grayish  powder.  It  is 
employed,  pharmaceutically,  chiefly  in  the  manufacture  of  dusting 
powders  for  use  in  treating  chafing  of  the  skin. 
One  specimen  yielded  the  following  analysis :
