friable coal, lustrous ; does not soil the hands ; does not swell up on heating ; dark-brown streak ; ash white. Sulphur, 0-5 per cent. Analysis of Hikutaia Bock. (E. J. Banks and H. Groucher.) Si0 2 , 64-20 per cent.; FeO, 746 per cent.; A1 2 0 3 , 10-69 per cent.; MgO, 6-21 per cent.; CaO 2 per cent.; Mv0 2 , 0-56 per cent.; Na 2 0, 3-93 per cent.; K 2 O, 1-47 per cent.; moisture, at 100° C. 0-84 per cent.; loss on ignition, 2-66 percent.: 100-02 per cent. The rock was black in colour' partly decomposed, and greasy to the touch. Analysis of Bock from Thames at Depth of 400 ft., in Deep Sinker. (W. A. MacLeod.) Si0 2 , 54-12 per cent.; A1 2 0 3 , 3-36 per cent.; FeO, 13-57 per cent.; CaO, 6-53 per cent.; MgO, 1-56 per cent.; K 2 O and Na 2 0, 2-74 per cent.; moisture, 10-74 per cent.; loss on ignition, 7-44 per cent.: 100-06 per cent. The sample was brown-red in colour, showed slickensided faces, was greasy to the touch, and appears to be a crushed andesite. Syllabus of Instbuction. The following is the syllabus of instruction followed during 1897-98 : — General and Mining Geology. —(Lecturer, the Director, Mr. F. B. Allen, M.A., B.Sc.) Physical Geology. —The earth as a planet, its form and motions ; geological climate; the atmosphere ; ocean ; solid crust; the interior of the earth. Dynamical Geology. —Metamorphism ; agencies modifying the crust of the earth—atmospheric, aqueous, chemical; weathering; sedimentation ; classification of deposits—mechanical, aqueous, organic, and chemical; denudation and erosion. Structural Geology. —Stratification ; jointage ; contortion ; faults ; conformity ; unconformity ; dip and strike ; cleavage ; metamorphic rocks ; intrusive sheets, bosses, dykes, fissures; formation of quartz veins, lodes, and metallic deposits; dynamics of lodes ; recovery of lost lodes. Geological Surveying. —The practice of running natural sections ; noting dip, strike, and inclination of strata and lodes; mapping geological formations ; collection of mineral and rock specimens. Stratigraphical Geology. —Classification of plants and animals; fossils ; blending of species; geological record ; the study of characteristic life, and distribution of formations from archsean to recent times, with special reference to the geology of New Zealand. Mineralogy and Blowpipe Determination. —(Lecturer and Instructor, the Director.) Systematic Mineralogy. —(l.) Physical properties of minerals, their hardness, specific gravity, &c (2.) Optical properties —refraction, reflection, polarisation, lustre, phosphorescence. (3.) Chemical properties. (4.) The application of the blowpipe, colour-tests, &c. (5.)
