1.  Define  Specific  Gravity.  What  instruments  are  employed  in  ascertaining 
the  specific  gravity  of  solids  and  liquids?  How  do  you  take  the  specific 
gravity  of  a  substance  lighter  than  water;  and  why  is  it  necessary  to  fix 
upon  one  constant  temperature  in  taking  specific  gravities? 
2.  What  do  the  following  terms  mean,  in  a  pharmaceutical  sense:  "  Moder- 
ately Fine  Powder,"  "Saturated  Solution,"  "  Flocculent  Precipitate,"

gravity,  solubilities,  and  boiling  point.  From  what  source  is  it  obtained  ? 
What  are  its  medical  properties,  and  into  what  officinal  preparations  does 
it  enter  ? 
4.  Give  the  officinal  formula  for  making  Spiritus  Aetheris  Nitrosi.  Why  are 
Copper  Turnings  used  ;  and  what  is  the  nature  of  the  residue  left  in  the
