Topography of the Punjaub Oil Region.” pi 
It aimed at a somewhat detailed account of the topography of 
the oil region ; its situation, general features, special features, 
ete. The different places were mentioned where each kind of topo- 
graphy is to be seen, and its causes and simple laws pointed 
out; chiefly in order to show the great usefulness of careful topo- 
graphical studies to geology. A short sketch of the geology of the 
region, aside from structure, was also added. Bie 
he general section of the rocks of the region is as follows, 
below the new and old alluvians: a
