Professor  Sayre  thought  the  presence  of  ammonium  chloride  or  other  salts  in 
the  precipitated  calcium  phosphate  exercised  an  ill  effect.  The  committee 
recommended  that  such  of  the  aquae  medicatae  as  are  now  directed  to  be  made 
by  trituration  with  precipitated  calcium  phosphate  be  made  either  by  agitation 
of  the  oils  with  hot  water  and  subsequent  filtration,  or  by  the  use  of  a  double 
filter,  the  inner  one  a  size  smaller  than  the  outer  and  evenly  saturated  with  the 
oil  and  the  outer  one  wetted.  Professor  Hallberg  objected  to  the  use  of  pre- 
cipitated calcium  phosphate  on  account  of  the  soluble  salts  which  were  likely 
to  be  present.  He  strongly  recommended  the  hot  water  method,  and  was  cor- 
roborated in  his  views  by  Mr.  Alpers.  The  committee  desired  that  experiments 
be  made  on  the  use  of  dextrin  syrup  or  glucose  in  place  of  glycerin  in  the 
preparation  of  fluid  extracts  containing  resinous  matter.  It  was  also  recom- 
mended that  experiments  be  made  with  acetic  acid  in  the  manufacture  of  these 
preparations  and  tinctures,  to  replace,  in  part,  at  least,  the  alcohol  now  directed. 
The  chairman  of  the  committee  stated  that  numerous  complaints  had  been 
made  to  the  effect  that  soap  liniment  became  solid  at  the  ordinary  temperature 
of  the  room.  The  committee  suggested  that  this  matter  be  investigated  and 
assigned  as  the  cause  of  the  trouble  either  an  impurity  in  the  soap  or  that  the 
Pharmacopoeia  had]  directed  too  large  a  quantity.  Professor  Hallberg  stated 
that  the  presence  of  much  stearate  in  the  soap  would  tend  toward  such  a  con- 
dition. Professor  Remington  said  that  this  trouble  usually  arose  from  inatten- 
tion to  the  amount  of  moisture  present  in  the  soap,  and  recommended  the  use 
of  the  shavings  that  are  obtained  when  the  bars  of  soap  are  cut  into  cakes  for 
sale.  The  committee  thought  the  melting  point  should  be  stated  for  aloin,  and 
that  the  solubility  should  be  changed.  They  called  attention  to  the  incorrect- 
ness of  the  chemical  formula,  KfiFe(CN)12,  for  potassium  ferricyanide,  as 
stated  on  pages  477  and  520.  On  page  360,  under  sodium  hypophosphite,  in  the 
second  line  of  the  second  paragraph,  mercuric  chloride  should  be  read  instead 
of  ammonium  chloride. 
The  committee  thought  the  term  isonitril,  which  is  used  in  describing  the 
tests  for  acetanilid,  should  be  superseded  by  the  term  phenilisocyanide,  for  the 
reason  that  the  former  term  is  meaningless.  They  desired  to  limit  the  use  of 
the  termination  ol  to  phenols  and  alcohols,  prohibiting  its  use  as  applied  to 
aromatic  hydrocarbons,  which  have  a  generally  applied  English  name.  To 
illustrate  their  suggestion,  they  stated  that  what  is  now  called  benzol  and  toluol 
should  be  known  respectively  only  as  benzene  and  toluene.  They  considered 
that  the  names  hydrochlorate  and  hydrobromate,  as  applied  to  salts  of  hydro- 
chloric and  hydrobromic  acids,  are  incorrect  ;  that  these  should  be  changed  to 
hydrochloride  and  hydrobromide.  They  thought  that  the  name  chloral  as  a 
heading  for  something  that  is  not  chloral,  but  chloral  hydrate,  is  an  error,  and 
that  the  full  name  should  be  stated.  The  melting  point  of  atropine  should  be 
1150  instead  of  1080  C.  The  committee  thought  a  distinction  should  be  made 
between  Erythroxylon  Bolivianum  (Huanco  leaves)  and  Erythroxjlon  Spruce- 
anum  (Truxillo  leaves)  as  there  is  a  microscopic  difference  in  the  leaves  and  a 
decided  difference  in  the  yield  of  alkaloid.  The  adoption  of  standards  of 
strength  and  methods  of  assay  were  recommended  for  coca  leaves,  bella- 
donna leaves  and  root,  and  henbane  leaves.  In  the  opinion  of  the  com- 
mittee, stramonium  seed  should  be  superseded  by  the  leaves  and  stems  for  the 
following  reasons,  viz.:  because  the  leaves  and  stems  contain  more  alkaloid,
