A  paper  by  Prof.  Remington  in  answer  to  Query  18,  on  fluid  extract  of  liquorice: 
root,  was  read  and  referred  for  publication.  The  formula  proposes  to  exhaust  16 
troyounces  of  powdered  liquorice  root  with  a  mixture  of  4  fluidounces  of  alcohol^ 
3  °f  glycerin,  8  of  water  and  1  of  stronger  water  of  ammonia  ;  the  percolation  is 
continued  with  alcohol  diluted  with  3  times  its  bulk  of  water  until  24  fluidounces 
are  obtaiiied,  the  first  12  of  which  are  reserved  and  the  remainder  evaporated  to  4 
fluidounces  and  then  mixed  with  the  reserved  portion.  Prepared  in  this  way,  six 
cubic  centimeters  of  the  fluid  extract,  when  treated  with  a  slight  excess  of  diluted, 
sulphuric  acid,  yielded  a  precipitate  of  glycyrrhizin,  which  after  washing  and  drying; 
weighed  0*967  gram,  or  a  larger  quantity  than  from  five  other  fluid  extracts,  made  by* 
different  processes.  Syrupus  glycyrrhiza  may  be  made  by  mixing  2  fluidounces  of 
this  fluid  extract  with  14  fluidounces  of  simple  syrup.  Elixir  glycyrrhiza  aromaticus- 
may  be  obtained  by  mixing  2  fluidounces  of  the  fluid  extract,  4  of  alcohoL,  6  of;' 
syrup,  10  minims  of  oil  of  cloves,  5  minims  of  oil  of  cinnamon,  12  minims  of  oik 
of  nutmeg  and  sufficient  water  to  make  one  pint.
