October  1908™' }  American  Pharmaceutical  Association.  487 
The  authors  stated  that  in  view  of  our  food  and  drug  laws,  state 
and  national,  the  instability  of  chlorinated  lime  and  of  solution  of 
chlorinated  soda,  is  a  menace  to  every  dispenser  of  these  two  com- 
pounds. It  is  useless  for  the  retailer  to  comfort  himself  with  the 
assurance  that  no  food  official  would  prosecute  the  seller  of  these 
unstable  products,  nor  is  it  wise  to  dismiss  the  subject  with  the 
short  answer  that  Labarraque's  solution  is  rarely  called  for.  The 
fact  still  remains  that  30  per  cent,  chlorinated  lime,  and  2.4  per  cent. 
Labarraque's  solution  are  official ;  that  these  strengths  are  practically 
never  possessed  by  the  chemicals  dispensed  by  the  retailer ;  and  that 
unless  other  strengths  are  distinctly  stated  on  the  label,  it  is  un- 
derstood that  the  products  are  of  pharmacopceial  strength. 
To  the  writers  the  only  apparent  way  out  of  the  dilemma,  as  far 
as  chlorinated  lime  is  concerned,  will  be  the  reduction  of  the  official 
strength  of  that  chemical  to  25  per  cent,  at  the  next  pharmaco- 
pceial revision;  and  as  for  solution  of  chlorinated  soda,  it  should 
be  freshly  prepared  by  the  pharmacist,  and  that  by  a  modified  recipe, 
such  as  suggested  in  this  paper  and  from  chlorinated  lime  of 
unimpeachable  quality. 
In  this  connection  the  writers  suggest  to  those  wholesalers  who 
specialize  in  chlorinated  lime,  the  advisability  of  dispensing  same 
in  12  Gm.  lots  in  sealed  glass  tubes,  similar  to  those  used  for  amyl 
nitrite.  By  having  the  tube  long  enough,  it  should  be  possible  to 
use  the  heat  necessary  to  seal  the  tube  without  unduly  heating  the 
chemical  and  this  device  may  prevent  loss  by  volatilization.  That 
the  chemical  deteriorates  even  when  sealed  with  paraffin  in  cork 
or  glass-stoppered  bottles,  the  data  found  in  this  article  clearly 
show. 
The  quantity,  12  Gm.  of  chlorinated  lime,  is  suggested  as  afford- 
ing a  convenient  basis  for  making  up  100  cubic  centimeters  of 
Labarraque's  Solution  by  the  modified  recipe  suggested  in  this  paper. 
Proteid  Compounds  of  Heavy  Metals. 
By  H.  A.  B.  Dunning. 
The  paper  consisted  of  a  collection  of  notes  on  the  preparation 
of  compounds  of  albumen  and  peptonized  albumen  with  iron,  mer- 
cury, silver  and  copper.  Referring  to  the  iron  compounds,  various 
methods  were  used  to  produce  them.  The  object  of  the  experimen- 
tal work  was  to  devise  satisfactory  processes  for  the  production  of
