care  should  be  taken  that  the  grease  should  ba  removed  from  the  iron, 
and  that  he  had  found  iron  card  teeth  preferable  to  iron  raspings; 
also  that  it  was  necessary  to  heat  the  solution  to  ensure  the  end 
reaction. 
Mr.  Shinn  remarked  that  he  used  to  put  a  coil  of  iron  wire  in  the 
bottles  containing  the  syrup  to  ensure  the  iron  being  kept  in  the 
ferrous  state. 
Melvin  W.  Bamford  read  a  paper  on  "  Benzoinated  Lard,"  and 
exhibited  some  specimens.  (See  page  29.)  Mr.  Wiegand  said  that 
he  found  it  best  to  expose  as  great  a  surface  as  possible  to  the  finely 
powdered  benzoin  at  as  low  a  temperature  as  possible,  and  then 
strain  the  product  through  canton  flannel.  Professor  Lowe  referred 
to  Mr.  Beringer's  remarks  made  at  a  previous  meeting  (see  Vol.72, 
p.  559),  and  also  to  the  method  of  making  benzoinated  lard  which 
was  employed  by  Mr.  Webb.  The  principle  was  the  same  as  that 
referred  to  by  Mr.  Wiegand,  in  that  alternate  layers  of  powdered 
benzoin  and  lard  were  digested  at  a  temperature  just  sufficient  to 
melt  the  lard.  Mr.  Shinn  remarked  that  he  used  to  dissolve  the 
benzoin  in  alcohol  and  then  digest  this  with  the  melted  lard  until 
the  alcohol  evaporated,  after  which  the  powder  was  allowed  to 
settle,  and  when  cool  the  upper  part  was  removed.  Mr.  Haussmann 
said  that,  in  his  experience,  the  benzoin  in  either  an  alcoholic  or 
ethereal  solution  was  likely  to  become  shredded,  particularly  in  an 
ointment  consisting  of  lard  and  wax. 
Mr.  Bamford  said  that  there  was  one  point  to  which  he  desired 
to  call  particular  attention,  that  in  making  leaf  lard  from  the  fatty 
tissues  no  water  was  employed,  this  being  the  process  proposed 
by  Professor  Redwood  and  adopted  by  the  British  Pharmacopoeia. 
The  usual  custom  by  manufacturers  of  lard  is  to  wash  the  lard  with 
water,  and  some  of  it  is  then  removed  by  heat. 
In  discussing  the  subject,  Professor  Kraemer  remarked  that  he 
was  heartily  glad  that  Mr.  Bamford  had  taken  up  this  subject,  as  it 
demonstrated  what  could  be  done  if  pharmacists' really  desired  to 
secure  good  materials  wherewith  to  make  pharmaceutical  prepara- 
tions. It  has  been  supposed  that  a  good  leaf  lard  was  very  difficult 
to  obtain,  and  it  would  appear  that  the  method  of  making  the  lard 
from  the  animal  tissues  was  an  expensive  process,  whereas  Mr. 
Bamford  showed  that  it  was  an  economical  one. 
Mr.  Kebler  read  a  paper  on  "  The  Testing  of  Essential  Oils,"
