LECTURES ON GEOLOGY. 



The introductory lecture of the remarkably original and 

 successful course whose syllabus is given herewith, was delivered 

 on the 13th of January, 1894 ; notices of it and the final lecture 

 are given below. The lectures dealt mainly with matters that 

 could be observed in the country around Belfast, and each 

 lecture was followed by pratical work, dealing with some of the 

 methods by which rocks may be determined. 



1. Hardness ; specific gravity ; simple chemical tests. 



2. Pulverisation of the rock ; examination of its constituents ; 

 sifting ; use of polarised light in this method. 



3. Brief survey of the use of microscopic sections in studying 

 the structure of a rock. 



4. Examination of special types of rocks, igneous and sedi- 

 mentary, by various methods. 



5. Detection of shells, etc., in sands and clays, with a view to 

 determining the origin of such deposits. 



6. Tracing the origin of materials that have been removed to 

 a distance from their parent rock-mass.
