Tennant  is  between  8  and  11  a.m.,  or  after  4  p.m. 
ie  Course  commences  with  a  description  of  the  Physical  and  Chemical  characters  of 
rals  in  general.

re,  Colour,  Flexibility,  Double  Refraction,  Touch,  Taste,  Odour,  Streak,  Adhesion   to 
Tongue,  Magnetic  and  Electric  Properties,  Phosphorescence,  Specific  Gravity. 
[EMiCAL  Characters. — Use  of  the  Blowpipe,  Action  of  Acids,  &c. 
ie  principal  simple  Minerals  are  next  separately  considered,  and  the  readiest  mode  of

p,  Topaz — called  oriental  stones;  Spinel,  Turquoise,  Topaz,  Emerald,  Beryl,  Hyacinth, 
maline,  Lapis-lazuli,  &c. 
The  Metalliferous  Minerals  are  fully  described  in  the  Practical  Course. 
ie  Course  of  Instruction  includes  a  minute  description  of  all  the  substances  entering 
the  composition  of  Rocks,  and  of  those  minerals  which  are  also  used,  in  the  Arts, 
trated  by  an  extensive  collection  of  characteristic  specimens  and  diagrams  of  the  prin- 
[  crystalline  forms,  &c. 
GEOLOGY  AND  MINING. 
escriptive  Geology. — Classification  of  Rocks  into  Aqueous,  Volcanic,  Plutonic,  and 
imorphic. 
meral  Composition  of  Strata. — Arenaceous,  Argillaceous,  Calcareous. — Chronological 
sification  of  Sedimentary  Rocks,  with  descriptions  of  the  principal  fossils  belonging  to 
great  deposit.

rimary  or  Paleozoic  Series. — Permian,  Carboniferous,  Devonian,  Silurian,  Cambrian 
ups. 
he  modes  of  collecting,  cleaning,  and  arranging  Fossils,  Minerals,  and  Rock-specimens 
lescribed.     The  student  is  directed  how  to  proceed  in  examining  a  new  country,  to 
jet  and  record  his  observations,  and  to  mark  Iris  specimens  in  order  to  render  them 
al  to  more  experienced  geologists  at  home. 
ractical  Geology  in  its  application  to  Mining,  Engineering,  Architecture,  and 
iculture. 
hie  lessons  delivered  on  the  subject  of  Geology  are  intended  to  have  especial  reference 
e  important  practical  applications  of  that  science  to  Engineering,  Mining,  Architec- 
and  Agriculture.     The  Granites,  Syenites,  Porphyries,  Greenstones,  Clays,  &c.  are 
ribed,  and  the  minerals  peculiar  to  each  noticed. 
he  application  of  Geology  to  pursuits  connected  with  mining  operations  for  Coal, 
Copper,  Tin,  Silver,  Gold,  Mercury,  Antimony,  Zinc,  Cobalt,  &c.  are  specially 
idered. 
Tennant  possesses  a  well-arranged  collection  of  Minerals  and  Rocks,  and  specimens 
uilding-stone.     He  also  supplies  elementary  collections  from  £2  2s.  to  £52  10s. 
order  more  fully  to  exemplify  the  applications  of  the  Science,  Mr.  Tennant  occasion- 
accompanies  his  Class  to  various  Museums  in  London,  including  the  Museum  of  Prac- 
l  Geology  and  the  British  Museum ;  also  on  excursions  into  the  country,  in  which  the 
al  field°work  of  the  Geologist  is  explained  and  illustrated.  There  is  an  Examination 
ae  close  of  the  course,  by  which  the  progress  of  the  students  is  tested. 
Prof.  Tennant's  Lectures  on  Mineralogy  at  King's  College  are  given  on  Wednesday 
Friday  mornings  from  9  to  10  during  Michaelmas  and  Lent  Terms,  and  on  Thursday 
lings  from  8  to  9.     The  public  are  admitted  on  paying  the  College  fees.
