It  is  not  impossible  that  the  atomizer,  as  a  means  of  refrige- 
ration, may  be  advantageously  applied  in  some  pharmaceutical 
and  chemical  operations  on  a  small  scale,  where  it  it  is  desirable 
to  have  a  low  temperature  for  a  short  time ;  for  instance,  in 
making  suppositories,  where  a  difficulty  occurs  in  separating  them 
from  the  moulds,  a  few  moments'  action  of  a  Bergson's  tube 
with  ether  or  rhigolene,  would  cause  the  necessary  shrinkage  ; 
or  in  testing  oils  by  reduced  temperature. 
AUBERGIER'S  SYRUP  OF  LACTUCARIUM. 
By  William  Procter,  Jr. 
Previous  to  the  introduction  of  Syrup  of  Lactucarium  into  the 
Pharmacopoeia,  Aubergier's  preparation  was  that  chiefly  used  in 
Philadelphia,  and  perhaps  elsewhere  in  the  United  States.  The 
officinal  syrup  is  so  very  different  from  Aubergier's,  that  it 
has  continued  in  use  since  the  publication  of  the  Pharmacopoeia, 
and  apothecaries  are  not  always  satisfied  which  preparation  is 
intended  by  prescribers.  The  literal  translation  of  the  formula  for 
Aubergier's  syrup  is  not  adapted  to  ordinary  usage,  and  it  has 
been  deemed  useful  to  modify  the  manipulation  so  as  to  reach 
the  same  end. 
Take  of  Lactucarium,  (German),  half  an  ounce, 
Sugar,  granulated,  an  ounce, 
Simple  syrup,  four  and  a-half  pints, 
Citric  acid,  in  powder,  sixty  grains, 
Orange  flower  water,  four  fluidounces, 
Alcohol, 
Water,  each  a  sufficient  quantity. 
Triturate  the  lactucarium  with  the  sugar  until  it  is  reduced  to 
powder,  put  it  in  a  funnel  prepared  for  percolation,  pour  on 
diluted  alcohol  until  the  lactucarium  is  nearly  exhausted,  or  until 
ten  fluidounces  of  percolate  has  passed,  evaporate  to  two  fluid- 
ounces,  and  add  it  to  the  syrup,  previously  heated  to  boiling, 
and  mix  ;  continue  the  ebullition  slowly  until  the  whole  measures 
four  pints  and  six  fluidounces.     Then  add  the  citric  acid  and
