to  be  mainly  due.  What  is  the  dose  of  the  drug,  and  of  its  pharmaceutical 
preparation?  Name  some  other  (non-pharmacopceial)  drugs  obtained  from 
ferns,  and  state  their  medical  uses. 
C— Barks  of  Lanracece — Name  the  pharmacopoelal  barks  obtained  from 
plants  of  the  order  of  Laurineae,  and  state  in  each  case  the  botanical  name  and 
habitat  of  the  plant ;  whether  (and  if  so  to  what  extent)  any  portion  of  the 
tissues  of  the  bark  is  usually  removed  ;  the  characteristic  structure  of  the  bark; 
the  medicinally  or  pharmaceutically  important  principles  ;  the  chief  proximate 
constituent  of  the  volatile  oil ;  and  the  influence  of  nitric  acid  or  other  oxidiz- 
ing agent  upon  the  volatile  oil. 
D — Buchu — Name  the  plants  and  their  habitat  from  which  buchu  leaves  are 
obtained.  -  Describe  the  different  commercial  varieties  of  the  drug.  Which 
tissue  of  buchu  leaves  contains  mucilage  ?  What  other  parts  of  the  plants  are 
sometimes  mixed  with  the  drug,  and  what  is  their  medicinal  value  ?  What 
other  leaf  is  sometimes  substituted  for  long  buchu,  and  how  may  it  be  distin- 
guished from  the  latter?  Give  the  percentage  and  characteristics  of  the  volatile 
oil  of  buchu.  State  the  medical  properties  and  dose  of  buchu  leaves.  Name 
some  other  drugs  from  the  natural  order  yielding  buchu,  and  state  their  medi- 
cinal properties. 
E — Arbor  vitce — Name  the  plant,  its  habitat  and  the  part  directed  by  the 
Pharmacopoeia.  Describe  the  drug.  Name  its  constituents  and  their  properties. 
What  are  the  medical  properties  and  dose  of  the  drug  ?  Name  the  officinal 
volatile  oils  obtained  from  coniferse.  State  from  which  drugs  these  volatile 
oils  are  distilled.    Give  their  chemical  composition. 
F—Hops — Name  the  plant,  its  habitat  and  the  part  used.  Describe  the  drug, 
specifying  the  arrangement  and  character  of  its  various  parts.  From  which 
portion  of  hops  is  lupulin  obtained  ?  How  is  lupulin  collected  ?  Explain  its 
structure.  Name  the  constituents  of  lupulin.  Also  the  constituents  of  hops 
deprived  of  lupulin.  What  effect  has  exposure  to  the  air  upon  hops  and 
lupulin  ? 
G — Seeds — Name  the  pharmacopceial  seeds  containing  albumen  (perisperm) 
and  a  straight  embryo,  and  give  in  each  case  the  botanical  name  and  habitat 
of  the  plant ;  the  structure  of  the  seed  ;  the  important  proximate  constituents, 
with  the  average  percentage  of  each  ;  also  the  chemical  nature  of  these  constit- 
uents, and  the  characteristic  reactions  of  some  of  them.  . 
H — Asafetida — Name  the  plants  yielding  asafetida,  and  give  the  habitat  of 
each.  From  which  part  of  the  plants  and  by  what  process  is  asafetida 
obtained  ?  Describe  the  drug.  What  impurities  are  usually  met  with  in  the 
commercial  drug,  and  in  which  portion  of  it  ?  State  the  effect  of  alcohol,  ether 
and  water  upon  asafetida.  Name  the  proximate  principles  and  the  percentage 
of  each.  What  is  the  chemical  composition  of  the  characteristic  odorous 
principle  ?  Give  the  medical  properties  and  dose  of  asafetida. 
I— Insects — Name  the  officinal  insects,  and  the  order  to  which  each  belongs. 
How  are  these  insects  collected?  Give  the  size,  shape  and  color  of  each  kind  of 
these  insects.  Name  their  important  constituents.  Give  the  behavior  of  the 
valuable  constituents  to  simple  solvents  and  to  alkalies.  What  impurities  are 
sometimes  met  with  in  the  commercial  insects,  and  how  may  such  impurities 
be  detected?
