The  B.P.  as  a  Standard. 
By  D.  B.  Dott. 
The  author  is  of  opinion  that,  although  the  B.P.  is  admittedly  the 
standard  according  to  which  pharmacists  are  bound  to  prepare  all 
medicines  which  are  official,  the  medicines  must  only  be  regarded  as 
being  of  official  standard  when  they  are  dispensed  to  the  order  of  a 
physician,  or  where  the  conditions  and  circumstances  of  sale  imply 
that  the  medicines  are  of  that  standard.  He  also  opposes  the  idea 
that  it  should  be  considered  possible  to  prove  the  presence  of  the 
full  amount  of  any  ingredient  ordered  in  the  B.P.  formula  for  a 
given  preparation  some  time  after  that  preparation  has  been  made. 
Examples  are  given  of  a  few  confused  interpretations  of  the  Phar- 
macopoeia regarded  as  a  standard,  and  it  is  suggested  that  a  more 
intelligent  and  reasonable  interpretation  of  existing  laws  be  re- 
quired. 
Liquor  Ferri  Phosphatis  cum  Quinina  et  Strychnina. 
By  H.  J.  Henderson. 
As  a  result  of  the  examination  of  ten  samples  of  liquor  ferri 
phosphatis  cum  quinina  et  strychnina  the  author  showed  that  all  the 
samples  which  contained  over  4  grammes  of  alkaloid  in  100  c.c.  gave 
unmistakable  reactions  for  chlorides,  a  circumstance  which  points  to 
the  probable  substitution  of  the  acid  hydrochloride  of  quinine  for  the 
less  soluble  sulphate.  When  it  was  found  that  sulphates  were  con- 
spicuous only  by  their  absence,  the  supposition  received  further 
confirmation.  Of  the  other  samples,  one  differed  from  the  others  in 
that  it  contained  alcohol  in  considerable  quantity,  but  the  small 
amount  of  liquor  at  the  disposal  of  the  author  made  a  trustworthy 
estimation  of  alcohol  impossible.  In  two  samples  the  alkaloidal 
contents  were  1*30  .and  1*25  per  cent,  respectively.  Sulphates  were 
present,  but  no  chlorides  were  found.  In  another  sample  glycerin 
was  found,  the  glycerin  playing  the  double  part  of  preservative  and 
solvent.  All  these  results  tend  to  confirm  the  impression  that  a 
liquor  ferri  phosphatis  cum  quinina  et  strychnina,  one  volume  of 
which  when  diluted  with  three  volumes  of  simple  syrup  shall  form
