CHEMISTRY. 
A — Write  the  chemical  reactions  for  the  preparation  of  pure  Carbonate  of 
Soda  by  the  Leblanc  process,  naming  all  the  products.  Do  the  same  for  the 
"  Ammonia-Soda  "  process.    Do  the  same  for  the  Cryolite  process. 
B — What  is  the  composition  of  Sal- Ammoniac  ?  Of  Ammonii  Carbon  as  ? 
Of  Ammonii  Nitras?  Of  Ammonii  Sulphas?  Of  Ammonii  Phosphas? 
Write  the  chemical  reaction  for  the  decomposition  of  Sal-Ammoniac  by  quick- 
lime— for  the  decomposition  of  Ammonium  Nitrate  by  heat. 
C — Describe  the  metal  Aluminum.  Give  an  outline  of  the  more  important 
processes  for  its  manufacture.  Mention  any  important  uses  of  the  metal  or 
its  alloys. 
D— Write  the  chemical  formulas  for  the  following  officinal  salts  of  iron  : 
Chloride,  Hypophosphite,  Phosphate,  Oxalate,  Sulphate,  Ferrocyanide  and 
Nitrate.  State  by  what  tests  Ferrous  salts  can  be  distinguished  from  Ferric 
salts.  State  how  a  Ferrous  compound  can  be  converted  into  the  corresponding 
Ferric  compound. 
E — What  is  the  chemical  composition  of  "  White-I^ead ?"  How  is  it  made? 
What  uses  has  it  in  pharmacy  and  in  the  arts  ?  With  what  is  it  often  adulter- 
ated, and  how  can  the  adulteration  be  detected  ? 
F—  What  is  the  distinction  between  drying  oils  and  non-drying  oils — (a)  in 
chemical  composition  ;  (b)  in  physical  properties  ;  and  (<:)  in  practical  applica- 
tions ?    Give  illustrations  of  each  class. 
G — How  do  you  distinguish  the  Glucose  class  of  sugars  from  the  Sucrose 
class?  Describe  the  successive  changes  that  starch  undergoes  under  the  influ- 
ence of  dilute  acids  or  ferments.  Give  the  names  of  the  products  obtained 
from  starch,  and  state  how  they  may  be  identified. 
H — What  is  an  essential  oil,  and  how  do  they  differ  physically  and  chemi- 
cally from  the  fatty  oils  ?  Into  what  several  groups  may  these  essential  oils  be 
divided?  What  alteration  products  often  accompany  the  essential  oils  ?  What 
is  the  chemical  character  of  these  accompanying  products?  What  are  the 
pharmaceutical  and  technical  uses  of  the  essential  oils  and  their  products  of 
oxidation  ? 
/ — Write  the  graphic  formulas  of  Alcohol,  of  Aether,  of  Acidum  Carbolicum, 
of  Acidum  Benzoicum,  of  Acidum  Gallicum.  Give  the  correct  chemical  names 
of  "  Antifebrin,"  of  "Vanillin,"  of  "Antipyrin." 
K — Give  both  the  officinal  and  the  exact  chemical  names  for  the  following 
compounds  : 
(1) 
(2) 
(3) 
C  H3 
CH, 
C   H2 -  OH
