samples  of  the  mixtures  to  be  tested,  there  were  added  5  Mils  of 
glacial  acetic  acid,  10  Mils  of  ten  per  cent,  potassium  iodide,  and 
sufficient  carbon  tetrachloride  or  chloroform  to  thin  the  material 
(usually  about  5  Mils)  ;  then  a  few  drops  of  starch  test  solution, 
and  finally,  from  a  burette,  sufficient  tenth-normal  sodium  thiosul- 
phate  solution  to  discharge  the  color. 
Each  Mil  of  tenth-normal  sodium  thiosulphate  solution  corre- 
sponds to  0.0177  Gram  of  available  chlorine. 
The  solvents  worked  with  were  too  samples  of  chlorosane;  two 
of  liquid  petrolatum ;  five  of  petrolatum ;  carbon  tetrachloride,  which 
gives  the  most  stable  solutions ;  kerosene,  which  is  very  destructive, 
in  fact  more  so  than  olive  oil.  Liquid  petrolatum  solutions  show 
some  loss  at  once,  but  preserve  a  fair  efficiency  for  a  month. 
Chlorosane  solutions  keep  practically  perfect  for  three  days,  and 
after  that  are  fairly  active  for  a  month.  Ordinary  petrolatums  are 
very  destructive  for  dichloramin-T ;  in  fact  the  efficiency  is  de- 
stroyed at  once.  The  amount  of  deterioration  is  the  same  regard- 
less of  the  color  impurities  in  the  petrolatum. 
The  conclusions  of  this  laboratory  investigation  of  dichloramin-T 
show  that  an  ointment  of  three  parts  of  surgical  paraffin  and  seven 
of  liquid  petrolatum  has  relatively  little  destructive  action  on  di- 
chloramin-T and  can  be  used  as  a  protective  dressing  on  wounds 
(burns)  treated  with  dichloramin-T-chlorcosane  solutions,  and  even 
as  a  basis  for  a  dichloramin-T  ointment. 
Ordinary  petrolatum,  irrespective  of  its  color,  is  very  destructive 
of  dichloramin-T,  and  cannot  be  used  effectively  with  it. 
Liquid  pertoleum  can  be  used  in  emergencies  as  a  vehicle  for 
dichloramin-T,  although  it  is  inferior  to  chlorcosane. 
Solutions  of  dichloramin-T  in  carbon  tetrachloride  are  very 
stable,  while  those  in  kerosene  or  in  olive  oil  spoil  very  rapidly. —

Cinchona  Research  in  Java. — It  may  not  be  generally  known 
that  a  cinchona  experiment  station  exists  in  Java.  This  station  was 
founded  in  191 1,  and  though  it  has  issued  a  few  bulletins,  it  has  not 
published  an  annual  report  until  this  year  when  the  reports  for  191 6 
and  1 91 7  were  issued  together.  The  station  has  for  its  object  the 
study  and  investigation  of  this  important  drug-plant  in  all  its  phases, 
and  to  be  in  a  place  to  give  advice  on  agricultural,  botanical,  chem- 
ical, and  entomological  matters  to  those  who  are  interested  in  the
