paper  was  accompanied  by  samples  of  liquid  preparations  of  various  drugs, 
and  in  calling  attention  to  these,  Prof.  Remington  said  that  acetic  acid  as  a 
menstruum  was  unsuited  for  some  drugs,  but  that  it  could  be  used  to  replace 
alcohol  in  a  number  of  instances. 
He  also  remarked  upon  the  question  of  the  cost  of  these  solvents,  and  stated 
that  an  extract  made  with  alcohol  was  six  times  as  expensive  as  one  made  with 
acetic  acid. 
The  subject  proved  to  be  of  special  interest  to  the  retail  pharmacists  present, 
and  several  of  them  reported  favorably  upon  its  use  in  making  preparations  of 
such  drugs  as  sanguinaria,  ergot  and  gentian. 
In  connection  with  this  subject,  Professor  Remington  showed  a  convenient 
device  for  controlling  the  flow  of  percolates,  which  he  recommended  as  much 
superior  to  the  rubber  tubing  directed  by  the  Pharmacopoeia.  The  principle 
embodied  was  that  of  a  valve  regulated  by  a  screw  adjustment.

A  paper  on  "Ammonol  "  was  presented  by  Mr.  Geo.  M.  Beringer  (see  p.  150). 
Samples  of  ammonol  from  an  original  package  and  ammonol  made  according 
to  a  formula,  which  the  author  proposed  for  the  compound  after  examination 
of  the  manufacturer's  product,  were  exhibited,  and  attention  directed  to  the 
complete  similarity  in  appearance  of  the  two  products.,  The  paper  elicited 
considerable  discussion,  during  which  the  frequency  with  which  physicians 
directed  ammoniated  acetanilid  was  remarked  upon. 
"A  Chemical  Analysis  of  Sage  Brush,  Artemisia  Tridentata,  Nutt."  was  the 
subject  of  a  contribution,  by  Mr.  Griffith  H.  Maghee  (see  p.  152).  The  flowers 
and  leaves  were  the  parts  examined,  and  in  addition  to  the  usual  plant  con- 
stituents, a  bitter  glucosidal  principle  was  obtained,  which  was  found  difficult 
to  separate. 
The  last  paper  on  the  programme  was  presented  by  Mr.  Chas.  H.  La  Wall, 
and  was  entitled,  "  Estimation  of  Ash  in  Various  Drugs"  (see  p.  137).  This 
was  the  first  of  a  series  of  papers  on  this  subject  which  the  author  intends  to
