A — Give  the  botanical  name  of  the  plant  from  which  Nux  Vomica  is 
obtained.  Which  part  of  the  plant  constitutes  the  official  portion  ?  Name  the 
two  chief  active  constituents  of  Nux  Vomica.  Name  another  official  drug 
which  contains  the  same  alkaloidal  constituents.  What  are  the  medicinal 
properties  of  Nux  Vomica  ?  What  is  the  ordinary  dose  of  its  most  important 
alkaloid?  Into  what  official  preparations  does  this  alkaloid  enter?  What 
strength  of  menstruum  is  directed  for  all  of  the  official  preparations  of  Nux 
-Vomica?  Name  the  official  preparations  of  Nux  Vomicaj  and  give  the  dose  of 
each.

which  the  litre  is  diminished.  If  a  litre  of  official  alcohol  be  placed  upon  one 
arm  of  a  scale  beam,  and  a  half  litre  of  official  Glycerin,  in  a  container  of  the 
same  weight,  were  placed  upon  the  other  arm,  how  many  cc.  of  water  would 
be  required  to  establish  a  balance,  and  into  which  container  must  it  be  put  ?
