fllabus of a Course of Private Lessons on Mineralogy, intended to facilitate 



the study of GEOLOGY and of the Application of MINERAL SUBSTANCES in 

 the ARTS, by J". TENNANT, F.R.G.S., Professor of Mineralogy at King's College, 

 London*, Mineralogist, by appointment, to Her Majesty, &c, 149 Strand, London, W.C. 



Terms, seven shillings a lesson, which occupies one hour. The most convenient time to 

 jr. Tennant is between 8 and 11 a.m., or after 4 p.m. 



The Course commences with a description of the Physical and Chemical characters of 

 inerals in general. 



Physical Characters. — Crystallization, Cleavage, Fracture, Frangibility, Hardness, 

 astre, Colour, Flexibility, Double Refraction, Touch, Taste, Odour, Streak, Adhesion to 

 p Tongue, Magnetic and Electric Properties, Phosphorescence, Specific Gravity. 



Chemical Characters. — Use of the Blowpipe, Action of Acids, &c. 



The principal simple Minerals are next separately considered, and the readiest mode of 

 stinguishing them is described. The following is the order adopted : — 



A. Earthy Minerals.— Rock-crystal, Amethyst, Cairngorm, Avanturine, Cat's-eye, Opal, 



lalcedony, Flint, Onyx, Agate, Carnelian, Heliotrope, Jasper, Hornstone, Chert, Garnet, 



lOcrase, Axinite, Epidote, Augite, Hornblende, Asbestos, Tremolite, Actinolite, Felspar, 



solites, Mica, Talc, Chlorite, Calcite, Fluor, Selenite, Baryta, Strontia, Salt, Cryolite, &c. 



[B. Combustible Minerals. — Sulphur, Bitumen, Coal, Jet, Amber, &c. 



C. Minerals used in Jewelry. — Diamond, coloured varieties of Corundum — Sapphire, 



uby, Topaz — called oriental stones ; Spinel, Turquoise, Topaz, Emerald, Beryl, Hyacinth, 



mrmaline, Lapis-lazuli, &c. 



I). The Metalliferous Minerals are fully described in the Practical Course. 



The Course of Instruction includes a minute description of all the substances entering 

 to the composition of Rocks, and of those minerals which are also used in the Arts, 

 ustrated by an extensive collection of characteristic specimens and diagrams of the prin- 

 al crystalline forms, &c. 



GEOLOGY AND MINING. 



Descriptive Geology. — Classification of Rocks into Aqueous, Volcanic, Plutonic, and 



etamorphic. 



Mineral Composition of Strata. — Arenaceous, Argillaceous, Calcareous. — Chronological 



assification of Sedimentary Rocks, with descriptions of the principal fossils belonging to 



ch great deposit. 



Tertiary or Cainozoic Series. — Cave-deposits, Crag, Isle of Wight, and Bagshot series, 



>ndon Clay, Woolwich Beds. 



Secondary or Mesozoic Series. — Cretaceous, Wealden, Oolitic, Triassic Groups. 



(Primary or Paleozoic Series. — Permian, Carboniferous, Devonian, Silurian, Cambrian 



oups. 



The modes of collecting, cleaning, and arranging Fossils, Minerals, and Rock-specimens 



e described. The student is directed how to proceed in examining a new country, to 



fleet and record his observations, and to mark his specimens in order to render them 



eful to more experienced geologists at home. 



Practical Geology in its application to Mining, Engineering, Architecture, and 



3RICULTURE. 



The lessons delivered on the subject of Geology are intended to have especial reference 



the important practical applications of that science to Engineering, Mining, Architec- 



re, and Agriculture. The Granites, Syenites, Porphyries, Greenstones, Clays, &c. are 



scribed, and the minerals peculiar to each noticed. 



The application of Geology to pursuits connected with mining operations for Coal. 



on, Copper, Tin, Silver, Gold, Mercury, Antimony, Zinc, Cobalt,'- &c. are specially 



isidered. 



Blr. Tennant possesses a well-arranged collection of Minerals and Rocks, and specimens 



Building-stone. He also supplies elementary collections from £2 2s. to £52 10s. 



In order more fully to exemplify the applications of the Science, Mr. Tennant occasion- 

 y accompanies his Class to various Museums in London, including the Museum of Prac- 

 al Geology and the British Museum ; also on excursions into the country, in which the 

 aial field-work of the Geologist is explained and illustrated. There is an Examination 

 the 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 

 1 Friday mornings from 9 to 10 during Michaelmas and Lent Terms, and on Thursday 

 mings from 8 to 9. The public are admitted on paying the College fees.
