The  Thalleioquin  Test, 
(  Am.  Jour.  Pharm. 
t      Aug.,  1880. 
shaking  up  the  liquid,  there  was  produced  in  its  stead  a  beautiful  rose 
color,  which  in  the  course  of  two  hours  assumed  a  brownish  color, 
which  changed  in  one  week  to  light  yellow. 
3.  Same  as  No.  2,  and  after  rose  color  was  produced  a  second  drop 
of  dilute  ammonia  deepened  the  color,  third  drop  changed  to  dark 
green,  and  fourth  drop  a  distinct  emerald  green. 
4.  Solution  of  sulphate  of  quinia  100  grains,  chlorine  water  10  drops, 
dilute  ammonia  i  drop  ;  same  effect  as  in  No.  2. 
5.  Solution  of  sulphate  of  quinia  100  grains,  chlorine  water  10  drops, 
dilute  ammonia  i  drop,  and  then  3  more  drops  were  added,  which  had 
the  same  effect  as  in  No.  3. 
6.  Solution  of  sulphate  of  quinia  lOO  grains,  chlorine  water  5  drops, 
dilute  ammonia  i  drop,  produced  green  color,  light  at  first,  but  deepens  by 
standing. 
7.  Solution  of  sulphate  of  quinia  (i  in  2,000)  lOO  grains,  chlorine 
water  5  drops,  dilute  ammonia  i  drop,  gives  green  color  well,  but  does 
not  change  to  rose  color. 
8.  Solution  of  sulphate  of  quinia  (i  in  4,000)  100  grains,  chlorine 
water  5  drops,  dilute  ammonia  i  drop,  gives  a  light  green  tint,  which 
fades  away  in  about  twelve  hours. 
B.  Solution  of  Sulphate  of  ^uinidia  and  fresh  Chlorine  Water, 
I.  Solution  of  sulphate  of  quinidia  (i  part  in  1,000)  100  grains,  chlo- 
rine water  25  drops  =  23  grains,  liquor  ammonia  i  drop  =  '8  grain  ; 
same  result  as  A  i. 
2  and  3.  Solution  of  sulphate  of  quinidia,  chlorine  water  and  dilute 
ammonia,  same  quantities  and  same  results  as  A  2  and  A  3. 
4.  Solution  of  sulphate  of  quinidia  100  grains,  chlorine  water  10 
drops,  dilute  ammonia  1  drop,  gave  green  color,  did  not  change  to  rose. 
5.  Solution  of  sulphate  of  qjjinidia  100  grains,  chlorine  water  5  drops, 
dilute  ammonia  i  drop,  gave  a  distinct  green  color  at  once. 
6.  Solution  of  sulphate  of  quinidia  (i  in  2,000)  lOO  grains,  chlorine 
water  5  drops,  dilute  ammonia  i  drop  ;  distinct  green,  lighter  than  B  5. 
7.  Solution  of  sulphate  of  quinidia  (i  in  4,000)  100  grains,  chlorine 
water  5  drops,  dilute  ammonia  i  drop,  gave  only  a  very  light  greenish- 
yellow  tint. 
The  above  experiments  were  performed  in  order  to  obtain  the 
smallest  amounts  of  chlorine  water  and  ammonia  which  would  take
