388  The  Tkalieioquin  Test,  {^'^•^^g"\^t:''^' 
corked  with  a  rubber  stopper,  was  nearly  colorless,  but  still  had  the 
odor  of  chlorine  ;  examined  by  the  mercury  test  before  mentioned,  it 
gave  an  acid  reaction  with  litmus  solution. 
C.  Solution  of  Sulphate  of  ^inia  and  old  Chlorine  Water ^  sp,  gr.  I '00 1 2. 
.  I.  Solution  of  sulphate  of  quiriia  (i  in  1,000)  100  grains,  chlorine 
water  25  drops,  solution  ammonia  i  drop,  gave  the  emerald-green  color. 
2.  Solution  of  sulphate  of  quinia  100  grains,  chlorine  water  15  drops, 
diluted  ammonia  ist  drop  produced  a  green  tint,  and  in  a  few  seconds 
the  solution  was  almost  colorless  and  required  3  drops  more  dilute 
ammonia  to  bring  back  a  pale  green  color.  (No  rose  color  was  pro- 
duced.) 
3.  Solution  of  sulphate  of  quinia  100  grains,  chlorine  water  10  drops, 
dilute  ammonia  1  drop,  gave  a  very  slight  yellowish-green  ;  3  drops  of 
dilute  ammonia  were  required  to  bring  out  the  emerald  color. 
4.  Solution  of  sulphate  of  quinia  (i  in  2,000)  100  grains,  chlorine  water 
5  drops,  dilute  ammonia  ist  drop  a  very  pale  green  ;  4  drops  were 
required  to  produce  a  marked  green  color. 
5.  Solution  of  sulphate  of  quinia  (i  in  4,000)  lOO  grains^  chlorine 
water  5  drops,  dilute  ammonia  I  drop,  and  then  same  as  C  4,  with 
same  result. 
D,  Solution  of  Sulphate  of  ^uinidia  and  old  Chlorine  Water ^  sp.  gr,  i*00i  2. 
1.  Solution  of  sulphate  of  quinidia  (i  in  1,000)  lOO  grains,  etc.  ; 
same  as  C  i,  with  same  result. 
2.  Solution  of  sulphate  of  quinidia  100  grains,  chlorine  water  15 
drops,  dilute  ammonia  i  drop,  produced  first  green,  then  a  light  rose 
tint,  which  deepened  on  standing. 
3.  Same  as  D  2  ;  a  second  drop  of  dilute  ammonia  brought  back 
green  color. 
4.  Solution  of  sulphate  of  quinidia  lOO  grains,  chlorine  water  10 
drops,  dilute  ammonia  i  drop,  gave  green  color. 
5.  Solution  of  sulphate  of  quinidia  ico  grains,  chlorine  water  5 
drops,  dilute  ammonia  i  drop,  produced  a  white  precipitate. 
6.  Solution  of  sulphate  of  quinidia  (i  in  2,000)  100  grains,  chlorine 
water  5  drops,  dilute  ammonia  i  drop;  same  effect  as  C  4. 
7.  Solution  of  sulphate  of  quinidia  (i  in  4,000)  in  same  manner  as  C 
4,  with  same  result,  the  green  which  was  produced  being  lighter  than  by 
D6.
