by Sir Charles Lyell, ^ 



Will be delivered by Prof, Tennant, at his residence, 149, Strand. Terms, 10s. 6d. 



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

 Metamorphic. i 



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

 Classitication of Sedimentary Rocks, with descriptions of the principal Fossils belonging to ^ 

 each great deposit. jj 



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

 London Clay, Woolwich beds. ^ 



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

 Lower), Triassic Groups. 



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

 Cambrian Groups. 



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

 be described. 



Syllabus of Lectures on Mineralogy, \ 



adapted TO facilitate the Study of GEOLOGY and of MINERAL SUBSTANCES - 

 \ USED IN the arts, which will be given by J. TENNANT, F.G.S., Professor of 

 ' Geological Mineralogy at King's College, London, on Wednesday and Friday mornings ^ 



from 9 to 10, and on Thursday evenings from 8 to 9. 

 The Course will commence with a description of the Physical and Chemical Characters of j 

 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, Phosphoi escence, 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, Heliotiope, 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 principal crystalline 

 forms, &c. 



The above Lectures commence at King's College early in October and end at Christmas.* 



To be followed by Lectures on Rocks and Metallic Minerals. 



The Lectures delivered on the subject of Geological Mineralogy are intended to have especial 



reference to the important practical applications of that science to Engineering, Mining, Archi- ^ 



tecture, 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, Zmc, Cobalt, &c., will be specially considered. 



The student is directed how to proceed in the examination of a new country, how to collect and '" 



record his observations, and to 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 i 



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



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



the Geologist is explained and illustrated. 'r 



The above Lectures commence at King's College in January and end at Easter. 



* During the Easter, Midsummer, and Christmas Holidays, Prof. Tennant gives a course 

 of Six Elementary Lectures on these subjects adapted to a Juvenile class, at his residence, 

 149, Strand, W.C, at 10 A.M. and 3 p.m. Terms, 10s. Qd. each course. \ 



Private Instruction on the above subjects is also given at 149, Strand, W.C, by Prof. ^ 

 Tennant, who can also supply Elementary Collections of Minerals, Rocks, and Fossils, 

 Apparatus, Books, Maps, Charts, Geological Hammers, &c.
