He  also  spoke  of  the  term  aromatic  as  being  applied  to  a  large  number  of 
organic  compounds,  and  that,  therefore,  the  term  did  not  mean  much.

ler,  in  commenting  upon  this  paper,  said  that  he  carried  out  experiments 
which  showed  that  infants  four  months  old  are  capable  of  digesting  starch:

ESTIMATION  OF  CODEINE. 
By  Henry  C.  C.  Maisch. 
The  author  takes  0*300  gramme  of  codeine  and  places  it  in  an  Erleumeyer 
flask  with  about  20  c.c.  of  water.  To  the  flask  is  attached,  by  means  of  a 
closely-fitting  soft  rubber  stopper,  a  delivery  tube,  of  the  following  construc- 
tion :  The  portion  connected  with  the  flask  has  an  internal  diameter  of  about 
y3e  inch.  About  4  inches  above  the  stopper  the  tube  is  bent  at  right  angles,  and 
6  inches  from  this  it  is  bent  again,  so  as  to  bring  this  portion  parallel  with  the 
first.  This  limb  is  about  4  inches  long,  and  is  fused  to  a  tube  having  a  j^-inch 
bore,  and  is  about  18  inches  long.  The  lower  end  of  this  is  drawn  out  to  a  bore 
of  about  yi  inch,  and  is  then  bent  upward.  This  tube  is  used  without  a  con- 
denser. The  end  of  the  delivery  tube  dips  into  20  c.c.  decinormal  hydro- 
chloric acid  diluted  with  sufficient  water,  so  that  the  orifice  is  about  %  incn 
below  the  surface  of  the  liquid.  After  the  apparatus  is  set  up,  add  10  c.c.  of  a 
10  per  cent,  solution  of  ammonium  chloride  to  the  flask  containing  the  codeine, 
and  this  is  at  once  attached  to  the  tube.  The  flask  is  now  heated  and  the  liquid 
kept  in  a  state  of  ebullition  until  about  one-half  has  distilled  over.  The 
acid  liquid  is  allowed  to  cool.  The  delivery  tube  is  then  washed  out  with 
water  and  the  washings  added  to  the  acid  solution.  This  is  now  titrated  with 
decinormal  KOH  solution,  using  coralline  or  rosolic  acid  as  an  indicator  ; 
316*31  grammes  of  codeine  (C]8H21N08  +  H2O)  or  298*35  grammes  anhydrous 
codeine  are  equivalent  to  36*37  grammes  of  absolute  hydrochloric  acid.  From 
this  we  have  1  c.c.  of  decinormal  HCl  representing  0*03163 1  gramme  of 
hydrated  codeine  or  0*029835  gramme  of  anhydrous  codeine. 
Among  those  who  discussed  this  paper  were  Mr.  Kebler  and  Professor

SOME  NOTES  ON  CHONDRUS. 
By  Henry  Kraemer. 
The  author  considered  some  of  the  morphological  characters  of  this  plant, 
and  referred  particularly  to  its  remarkable  mode  of  reproduction,  which  ap- 
pears to  be  that  of  a  triple  conjugation.  He  also  considered  the  collection  of 
the  drug  on  the  Massachusetts  coast,  and  advanced  some  reasons  for  modifying 
the  definition  of  the  U.S.  P.
