2S6 Mr. G. Tate on Glaciated Mocks. 



7. Anagallis c(Erulea. Tn the spring the seed of this 

 was sent me from the Highlaws, near Eyemouth, where it 

 grows on the surface of a trap-dike. Further on in the 

 season, at my present residence, while shedding aside some 

 corn to look for another plant, behold! the blue eye of this 

 Anagallis fixed upon me, upbraiding me for not looking 

 better about myself at home ; which had I and others done 

 at first, there would have been less need to note down these 

 novelties from year to year, Wildenow, " Florae Beroli- 

 nensis," p. 82, sanctions the distinction between this and 

 A. arvensis as specific, an idea that has not found favour in 

 Britain. 



Records of Glaciated Rocks in the Eastern Borders. 

 By George Tate, F.G.S., &c. 



The discovery of dressed and striated rocks on Abb's Head, 

 of which a notice is given by Mr. D. Milne Home in page 

 221, has revived the interest in these geological phenomena, 

 and induced me to look up my notes of similar facts, and 

 also to re-examine the Farn Islands, where the boulder clay 

 overlies the basalt. Even detached observations on such a 

 subject are worthy of record, as a contribution of materials 

 to help the solution of the problem as to the causes which 

 have produced glaciated surfaces in the border-land. 



1. In 1849 I gave an account in the Tyneside Transactions, 

 Vol. I., p. 348, of ice action on limestone in situ, lying below 

 boulder clay on Hawkhill Estate, near to Ratcheugh Crag ; 

 one part of the surface was flat and even, presenting a smooth 

 bright face, like marble artificially polished; other portions were 

 rounded and undulating, but still exhibiting the same mirror- 

 like polish ; over the whole surface were fine strise, from one 

 to six inches in length, some being one-tenth of an inch in 

 breadth ; there were also a few grooves, one quarter of an 

 inch in depth, one inch apart, parallel to each other, and 

 from one to six inches in length ; the general direction of 

 both strise and grooves was pretty nearly in the line of the 

 dip of the rock, from north to south. Blocks and fragments 

 of rock, polished and striated in a similar manner, were in 

 the overlying clay ; one large block of limestone, measuring 

 three feet long by two feet broad and two feet thick, was 

 striated and polished on the under surface, the strise having
