need  of  a  more  thorough  revision  than  they  have  obtained  in  this 
edition.  But  one  actual  dismissal  has  been  made,  that  of  Troches  of 
Magnesia.  The  substitution  of  Troches  of  Santonin  for  Troches  of 
Santoninate  of  Sodium  was  but  a  correction  of  this  at  once  acknowl- 
edged error  of  the  Pharmacopoeia  of  1880.  We  are  of  the  opinion 
that  Troches  of  Chalk  and  Troches  of  Ipecac  have  become  obsolete 
and  should  be  omitted,  and  as  the  preparation  of  peppermint  and 
ginger  lozenges  appears  to  be  left  to  the  confectioner,  these  likewise 
could  be  spared  from  the  official  list.  We  are  disappointed  in  not 
finding,  as  additions  to  the  class,  some  of  the  frequently  used 
troches,  such  as  those  of  benzoic  acid,  cocaine,  guaiac  and  its  com- 
pounds and  kino. 
The  compressed  lozenge,  although  almost  universally  used,  is  not 
officially  recognized.  It  could  have  been  adopted  in  place  of  the 
mass  lozenge  for  most  of  those  in  the  official  list.  As  a  class  the 
official  troches  are  not  in  harmony  with  that  marked  spirit  of 
progress  that  characterizes  the  volume  generally.  The  most 
displeasing  feature  is  the  absence  of  any  uniformity  in  the  size  of 
the  finished  products.  They  vary  from  -42  Gm.  in  Troches  of 
Cubeb  to  1-56  in  Troches  of  Potassium  Chlorate.  The  latter  are 
unnecessarily  large,  the  former  too  small.  Between  these  extremes 
we  find  all  sizes.  They  could  readily  have  been  classed  under  not 
more  than  two  sizes :  r  Gm.  and  -7  Gm.  or  75  Gm. 
With  the  exception  of  Troches  of  Santonin,  Troches  of  Ammo- 
nium Chloride  is  the  only  one  exhibiting  any  improvement.  The 
popular  muriate  of  ammonium  and  Licorice  lozenge  has  been  intro- 
duced, but  the  quantity  of  ammonium  chloride  has  been  reduced  to 
•1  Gm.  in  each  instead  of  about  -15  Gm.,  as  generally  made. 
The  official  ointments  exhibit  but  few  changes  of  note.  Oint- 
ment would  have  been  improved  by  substituting  benzoinated  lard. 
Ointment  of  Carbolic  Acid  and  Chrysarobin  Ointment  are  both 
reduced  to  five  per  cent,  instead  of  ten  per  cent.  Of  the  three 
astringent  ointments  formerly  official,  the  Ointment  of  Gallic  Acid 
has  been  dismissed  and  the  Ointment  of  Tannic  Acid  and  the  Nut- 
gall  Ointment  have  been  both  increased  to  20  per  cent.,  just  double 
the  strength  of  those  official  in  the  Pharmacopoeia  of  1880. 
The  formula  for  Ointment  of  Rose  Water  now  given  yields  a 
rather  odd  amount  of  product  985  to  990  Gm.  With  the  substitu- 
tion of  stronger  rose  water  for  rose  water  in  this  preparation,  it  has
