Syllabus of Six Elementary Lectures on Mineralogy, 



ADAPTED TO A JUVENILE AUDIENCE, 



WITH A VIEW TO FACILITATE THE STUDY OP GEOLOGY AND OF MINERAL 



SUBSTANCES used in the ARTS, which will be given by J. TENNANT, 

 F.G.S., Professor of Mineralogy at King's College, London, Mineralogist to 

 Her Majesty, &c, at bis residence, 149 Strand, London, W.C. 

 On January 3, «, 8, 11, 18, 15, 1823, at 2-p.in. 

 Terms :— Half a Guinea for the Course ; Five Shillings for Children of Fellows of the fol- 

 lowing Societies— Geological, Zoological, Chemical, Royal Microscopical, Royal Geographical, 

 Royal Horticultural, Geologists' Association, and Society of Arts. 



The Course will commence 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, Adhe- 

 sion to the Tongue, Magnetic and Electric Properties, Phosphorescence, Specific Gravity. 

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

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

 distinguishing them 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, Garnet, 

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

 Zeolites, 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, 

 Ruby, Topaz — called Oriental Stones ; Spinel, Turquoise, Topaz, Emerald, Beryl, Hyacinth, 

 Tourmaline, Lapis-lazuli, &c. 



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



The Course of Instruction will include 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. 



To "be followed in the Easter Holidays by Six Elementary Lectures 



on Geology. 



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, and Cam- 

 brian Groups. 



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

 will be described. 



In the Summer Holidays by Six Elementary Lectures on Practical 



Geology. 



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, Architecture, 

 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 Coal, 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 collect and record 

 his observations, and mark his specimens, in order to render them useful to more experienced 

 geologists at home. 



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

 his Classes to various Museums in London, including the Museum of Practical Geology and 

 the British Museum ; also on excursions into the country, in which the actual field-work of 

 the Geologist is explained and illustrated. 



'„.* Mr. Tennant's lectures at King's College will be resumed on Wednesday morning. 

 January 22, and the evening lectures on Thursday the 23rd.
