Strychnia,  reddish,  changing  to  blackish-coffee  color. 
Veratria,  dark  green. 
The  admixture  of  sugar  with  codeia  and  some  of  the  other  sub- 
stances which  in  their  pure  state  are  not  affected  by  sulphuric  acid, 
may  be  detected  by  the  addition  of  a  few  drops  of  this  liquid.  If 
sugar  of  milk  be  used  in  place  of  cane  sugar,  the  color  above  described 
does  not  appear  with  quinia,  and  is  much  less  intense  with  morphia 
and  codeia. 
SOLUBILITY  OF  SODIUM  AND  POTASSIUM  SALTS. 
By  John  Francis  Loehle,  Ph.G. 
From  an  Inaugural  Essay. 
The  author  has  determined  the  solubility  in  water  of  the  medicinal 
salts  of  sodium  and  potassium  of  fair  commercial  quality.    The  first 
columns  under  B  and  C  give  the  number  of  grains  dissolved  by  75  cc. 
or  J  fluidounce  of  distilled  water.
