Carius'  table,  which  for  a  long  time  enjoyed  a  high  reputation  for 
correctness,  must  now  give  way  to  those  of  his  successors,  who 
although  working  independently,  arrived  at  very  nearly  the  same 
results. 
The  authors  publish  a  further  table,  which  will  be  found  very 
useful.

Administration  of  Cod  L.iver  Oil.— The  Lyon  Medical  suggests  to 
combine  cod  liver  oil  with  an  equal  quantity  of  lime  water,  the  mixture  being 
flavored  with  vanilla,  lemon  or  other  aromatic.  Thus  prepared  it  is  pleasant  to 
take,  and  agrees  well  with  a  delicate  stomach.  Similar  formulas,  using  magne- 
sia or  potassium  carbonate,  are  published  in  Amer.  Jour.  Phar.,  1856,  p.  2.
