432 GLANCE AT THE GEOLOGY OF 



Although the maojnesian limestone had been 

 observed in all its true characters in the neigh- 

 bourhood of St. Bees' Head and Whitehaven, I 

 am not aware of any author having mentioned 

 the deposit in Low Furness, with the excep- 

 tion of Professor Sedgwick, who, at page 22 of 

 his Geology of the Lake district. Author's copy, 

 says, " I have before stated, that the magnesian 

 limestone rises from beneath the red marl and 

 sandstone of St. Bees' Head. It is of consider- 

 able thickness, and is well exposed in quarries 

 near the road leading from Whitehaven to St. 

 Bees. To the south of the valley of St. Bees it 

 degenerates into a thin magnesian conglomerate, 

 at the base of the red sandstone, and afterwards 

 for many miles further south, the limestone 

 disappears altogether ; but it re-appears in its 

 characteristic form near the village of Stank, in 

 Low Furness. It is generally of a yellowish 

 brown colour, and of a rather earthy structure, 

 and is often full of cells lined with pure carbonate 

 of lime. In the part of England here described, 

 I believe it contains no organic remains, but 

 many such remains are found in the same rock, 

 in its range through Yorkshire and Durham."
