Commenting  upon  the  table,  we  find  that  the  following  prepara- 
tions, are  contained  only  in  the  U.S. P.,  viz.:  Cerates,  Elixirs,  Emul- 
sions, Masses,  Oleoresins  and  Triturations.  The  following  only  in 
the  B.P.,  viz.:  Discs,  Lozenge  Bases,  Hypodermic  Injections,  Lo- 
tions, Oxymels,  Concentrated  Solutions  and  Tablets.  The  formula 
of  the  troches  of  the  B.P.  differ  from  those  of  the  former  edition, 
and  also  from  those  of  the  U.S.P.  in  being  calculated  for  a  single 
lozenge,  the  ingredients  being  then  mixed  with  one  of  the  four 
lozenge  bases  to  form  a  lozenge.  The  lozenge  bases  consist  of  the 
fruit  basis  flavored  with  black-currant  paste,  the  rose  basis  flavored 
with  rose-water,  the  simple  basis  without  flavor  and  the  tolu  basis 
flavored  with  tincture  tolu,  and  apparently  intended  as  a  vehicle  for 
salts  of  the  alkaloids.  The  hypodermic  injections,  which  comprise 
apomorphine,  cocaine,  ergotin  and  morphine,  are  not  popular  in  the 
United  States,  preference  being  given  to  the  hypodermic  tablets  on 
account  of  their  portability  and  permanence.  The  discs  (lamellae) 
are  minute  medicated  discs  of  gelatin,  each  about  fa  grain.  They 
comprise  the  following :  atropine,  grain,  cocaine,  fa  grain  (for- 
merly fa),  physostigmi  ne,  ygV(r  £ram>  and  a  new  one,  homatropine, 
Tjj1F  grain.  They  do  not  seem  to  be  used  by  our  oculists  to  any 
great  extent,  the  solutions  being  preferred.  The  concentrated  solu- 
tions (L;quores  Concentrati)  is  a  new  .class  of  preparations,  which
