SOUTH URAL. 
(MAP, PL. VII., AND COLOURED SECTIONS, PL. III. AND IV. 2 ) 
Introduction— Eastern Flanks of the Chain between the North Ural of the Miners and the South 
Ural of the Bashkirs, or between the river Issetz and the Zavod of Kishtymsk— From Kishtymsk 
and Mount Sugomak by Soimanofski Zavod to Zlatahst— Zlatailst. Taganai and environs- 
Tract extending westwards to Simsk— Transverse Section across the Cham, from the Paleozoic 
Strata of Pristau and the river Ai on the west, through the dolomitic and trappman rocks of 
Satkinsk, across the Ural Tau, to the highly crystalline and Metamorphic Rocks of Zlatoust and 
Miask upon the east— Tracts south of Minsk— Environs and Section of Cossatchi-datchi (oasis 
of Carboniferous Limestone)— Granitic Steppes between the Ural and Troitsk in Siberia- 
Eastern edges of the Ural from Vercb-Uralsk to Orsk— Transverse Section from Orsk to 
Orenburg— Oblique Section of the Chain from near Orenburg, by Preobrajensk and over the 
Irendyk Ridge to Verch-Uralsk— 1 Transverse Section of the whole Chain from Verch-Uralsk 
on the east to Sterlitamak on the west— Concluding observations on the Original Palaeozoic 
Structure of the Ural Mountains and the Changes they have undergone ; on the Inversion of 
the Strata and their direction in different parts of the Chain 421

ANCIENT SURFACE OF THE URAL MOUNTAINS AND THE ADJACENT COUNTRIES.- 
GOLD AND MAMMOTH ALLUVIA. 
Introductory View, showing the Mineral conditions of the Ural Chain when the Palaeozoic Conglo- 
merates were formed— No trace of Gold or Platinum in the ancient Cupriferous detritus on the 
West, nor in the Tertiary Grits on the East Flank of the Chain— The present Watershed and 
the Gold Ore both formed during a comparatively modern period. Auriferous Alluv ia at the
