 1. Geological Formations : these range from Lower Silurian to Per- 

 mian. 2. Geological Situation and Form of the Hematite Deposits : 

 these deposits occur as veins in Lower Silurian, but are both larger 

 and purer in the Mountain Limestone — as " flat deposits which follow 

 more or less the dip," as veins, and filling irregular hollows. The Moun- 

 tain-Limestone deposits are in three districts — Furness, Whitehaven, 

 and Millom. 3. Mineral Composition of the Deposits. W. W.

Gives reference to descriptions of raised beaches in the S. of Ireland, 

 and mentions that there is Carboniferous volcanic rock at Croghan

Calls attention chiefly to such boulders in the Till of the Glasgow 



district as are of limestone and clay-ironstone, referable, according to 



the author (from the fossils they contain), to the Campsie district.
