some distance above the outcrop of the Kirklinton Sandstone. As, 

 in addition, the shales underlying the St.-Bees Sandstone are 

 gypseous, both near Carlisle and at Barrowmouth, close to St. Bees 

 Head, the author classed the (Upper) Gypseous Shales as Permian, 

 and the Kirklinton Sandstone as Bunter. Eesting unconformably 

 on the Kirklinton Sandstone, in the district between Carlisle and 

 Kirklinton, are the Marls seen on the Eden between Stanwix and 

 Beaumont, and on the Line between Westlinton and Cliff Bridge, 

 Kirklinton. Their unconformity is shown by the fact that on the 

 Line they rest on the lower, or red, beds, and between Stanwix and 

 Beaumont on the upper, or white, beds of the Kirklinton Sandstone. 

 The Marls have therefore been classed as Keuper. So far as the 

 evidence goes, they appear to be very thin and to extend but a very 

 small distance south of the Eden. Lastly, the Lias appeared to the 

 author to be unconformable to all the beds below, and to rest 

 partly on the Gypseous Shales, partly on the Kirklinton Sandstone, 

 and partly on the Keuper Marls. Of the existence of Bhsetic beds 

 there was no evidence, all fossils hitherto found having been de- 

 termined by Mr. Etheridge (our President) to be Lower- Lias forms. 

 But the Lias-sections are so small and few in number, and the 

 ground so persistently drift-covered, that only a boring could settle 

 the question.

This paper is in continuation of two already published in the 

 Society's Journal (vol. xxxi. p. 603, and vol. xxxiv. p. 89). In sub- 

 sequent examinations of the southern part of the interior of British 

 Columbia the author has been able to find traces of glaciation in a 

 N. to S. direction as far as or even beyond the 49th parallel. Iron 

 Mountain, for instance, 3500 feet above the neighbouring valleys, 

 5280 feet above the sea, has its summit strongly ice-worn in direc- 

 tion N. 29° "W.-S. 29° E. Other remarkable instances are given 

 which can hardly be explained by local glaciers. Boulder-clay is 

 spread over the entire district ; terraces are cut in the rearranged
