NOTE on YORKSHIRE GEOLOGY. 



Perthshire Rocks in East Yorkshire.— In the Tenth Report of the 

 Yorkshire Boulder Committee, published in 'The Naturalist' for February 

 1897, Mr. H. B. Muff, B.Sc, F.G.S., and the writer recorded a number of 

 rocks, some of which could not at the time be definitely localised. Since 

 then Mr. Muff's appointment on the Geological Survey has brought him into 

 contact with Scottish geology and Scottish geolog-ists. To two of these 

 latter (Messrs. B. N. Peach, F. R.S., etc., and E. H. Cunningham-Craig 

 B.A., F.G.S.) he submitted several of the Robin Hood's Bay boulders. 

 These gentlemen have identified some undoubted Perthshire rocks aim 

 the specimens, and it is interesting- to note that they were principally 

 obtained from the Upper Boulder clay, which yields such a large propoi tion 

 of Cheviot rocks. Details of the boulders will appear in the next reporl 

 of the Yorkshire Boulder Committee. Mr. Muff has kindly presented the 

 specimens to the Hull Museum, where they can be at any time referred to.
