Glycerite  of  Tar. — The  omission  of  this  glycerite  from  the  new  Phar- 
macopoeia renders  desirable  a  preparation  that  may  be  made  without 
difficulty,  and  that  will  enable  the  pharmacist  to  furnish  the  various 
liquid  preparations  into  which  tar  enters,  in  a  cleanly,  easy  and  expe- 
ditious manner.  The  glycerite  made  by  the  following  formula  being 
miscible  with  water  in  all  proportions,  and  yielding  a  clear  liquid, 
commends  itself  to  the  favorable  consideration  of  pharmacists : 
Oil  of  tar   f^i 
Alcohol   ffii 
Glycerin  and  water,  each   f^iv 
Magnesium  carbonate,  q.  s.,  or   £vi 
Mix  the  oil  of  tar  with  the  alcohol,  and  rub  these  thoroughly  with 
the  magnesia  to  a  smooth  paste;  to  this  add  the  glycerin  and  water 
previously  mixed  together ;  put  the  mixture  into  a  well- corked  bottle, 
and  let  it  remain  for  several  days,  shaking  it  frequently ;  then  filter 
through  paper. 
For  prepaing  syrup  of  tar  add  f  Jii  of  glycerite  to  f^xiv  of  syrup. 
Tar  water  may  be  made  very  readily  by  using  £ss  of  glycerite  and 
water  sufficient  to  make  a  pint. 
Wine  of  tar  may  be  made  by  using 
Tar  ointment  may  be  made  much  more  easily  and  much  smoother  by 
using  two  drachms  of  oil  of  tar  with  six  drachms  of  simple  cerate. 
Choleate  or  Choleinate  of  Soda. — Under  this  name  a  preparation 
made  by  evaporating  purified  ox  gall  has  been  introduced  and  used  as 
a  very  gentle  and  efficient  laxative  in  cases  of  torpid  liver;  it  is 
thought  to  have  less  tendency  to  leave  the  bowels  in  a  torpid  state  after 
ceasing  to  use  it.  The  article  is  described  in  the  National  Dispensa- 
tory, but  seems  to  have  attracted  less  attention  than  it  merits.  It  is 
recommended  to  be  prepared  by  treating  fresh  ox  gall  with  twice  its 
bulk  of  alcohol ;  the  mixture  is  shaken  frequently  during  twelve
