The  following  table  shows  the  influence  of  time,  not  only  as  to 
quantity  of  microscopical  growth,  but  also  as  to  approximate  strength 
of  odor.  Those  marked  a  designate  the  water  in  corked  bottles  ;  b 
being  those  stoppered  with  cotton.

As  no  attempt  was  made  at  sterilization  of  the  waters,  objection 
may  be  raised  as  to  the  scientific  value  of  this  data,  yet,  representing 
the  normal  treatment  of  these  products  in  the  ordinary  pharmacy, 
we  may  glean  some  facts  of  possible  value. 
It  will  be  first  noticed  that  cinnamon,  peppermint  and  spearmint 
waters  are  comparatively  stable,  the  specimens  of  the  last  named 
being  almost  as  fine  after  seven  months  as  on  the  day  they  were 
made. 
Again,  we  see  that  using  a  plug  of  cotton  as  a  stopper,  unless 
accompanied  by  sterilization,  is  worthless,  and,  even  with  the  latter 
precaution,  loss  in  strength  is  to  be  expected.  Notice  that  in  every 
case,  save  spearmint,  the  cotton-stoppered  waters  were  either  odor- 
less or  of  faint  odor. 
Lastly,  we  find  that,  out  of  the  eight  samples  containing  appre-
