I. Introduction. — In the Quarterly Journal of the Geological 

 Society, xxxi, pp. 55-99, was published a paper, read in June, 1874, 

 on the "Glacial Phenomena of the Eden Valley and the Yorkshire 

 Dale-District." This gave a condensed account of the principal 

 facts and arguments relating to the results of ice work during the 

 Glacial Period over the area referred to in the title, based partly 

 upon work done in connection with the Geological Survey prior 

 to the date mentioned. Besides discussing matters whose chief 

 interest was more or less of a local character, the paper treated of 

 several matters of more general interest to geologists ; such as the 

 behaviour of large masses of land ice in motion, the origin of the 

 various and highly-complex drift deposits of the north-west of
