Syllabus of Private Lessons on Mineralogy, with a view to facilitate the study 



of GEOLOGY and of the Application of MINERAL SUBSTANCES in the ARTS, 



by J. TENNANT, F.G-.S., Professor of Mineralogy at King's College, London, Minera- 

 logist to Her Majesty, &c., 149 Strand, London, W.C. 



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

 Mr. 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 

 Minerals in general. 



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

 Lustre, Colour, Flexibility, Double Refraction, Touch, Taste, Odour, Streak, Powder, 

 Adhesion to the 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 

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



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

 Chalcedony, Flint, Onyx, Agate, Carnelian, Heliotrope, Jasper, Hornstone, Chert, Garnets, 

 Idocrase, Axinite, Epidote, Augite, Hornblende, Asbestos, Tremolite, Actinolite, Felspars, 

 Zeolites, Mica, Tale, Chlorite, Calcite, Fluor, Selenite, Barytes, Strontia, Salt, Cryolite, &c. 



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



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

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

 Tourmaline, Lapis-lazuli, &c. 



D. The Metalliferous Minerals w ill be fully described in the Practical Course. 



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

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

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

 cipal crystalline forms, &c. 



GEOLOGY AND MINING. 



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

 Metamorphic. 



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

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

 each great deposit. 



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

 London Clay, Woolwich Beds. 



Secondary or Mesozoic Series. — Cretaceous, Wealden, Oolitic (Upper, Middle, and 

 Lower), Triassic Groups. 



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

 Groups. 



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

 will be described. 



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

 Agriculture. 



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

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

 ture, and Agriculture. The Granites, Syenites, Porphyries, Greenstones, Clays, &c. will 

 be described, and the minerals peculiar to each noticed. 



The application of Geology to pursuits connected with mining operations for Coals, 

 Iron, Copper, Tin, Silver, Gold, Mercury, Antimony, Zinc, Cobalt, &c, will be specially 

 considered. The student is directed how to proceed in examining a new country, to col- 

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

 to more experienced geologists at home. 



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

 of Building -stone. 



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

 panies his Class to various Museums in London, including the Museum of Practical Geo- 

 logy and the Britism Museum; also on excursions into the country, in which the actual 

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

 close of the course, by which the progress of the students is tested.
