found together. This section also proves that the basalts of Antrim 

 are of the same age as the Tertiary basalts of Mull and Skye, and 

 contain similar fossils. 



In the Quarterly Journal of the Geological Society, vol. vii., 185 1, 

 p. 89, the Duke of Argyle describes the leaf beds of the Tertiary 

 age that occur in the Isle of Mull, and in the same Journal for 

 August, 1869, Mr. Baily describes the plant remains found at 

 Ballypallidy, County Antrim. In the Mull beds are found remains 

 of the plantain family, the pine tribe, equiseta, and ferns ; and 

 Sir Charles Lyell, on the authority of Professor Heer, attributes 

 one species to Sequoia Langsdorfi. At Ballypallidy Mr. Baily 

 identified Pinus Plutonis, like the cluster pine ; Cupressites, like 

 the ordinary cypress, and a Sequoia (which he called after the late 

 Mr. Du Noyer), like the red cedar of California ; together with 

 shrubs like buckthorn, and some insect remains. 



Mr. Tate and Dr. Holden, members of the Belfast Naturalists' 

 Field Club, in their paper on the Iron Ores of Antrim, published 

 in the Quarterly Journal of the Geological Society for May, 1870, 

 added several species to those enumerated by Mr. Baily, and also 

 showed that the plant remains were known and reported upon 

 before Mr. Du Noyer's. alleged "discovery;" and in this paper we 

 find an account of the plant remains from the ash beds on the 

 shore of Lough Neagh, collected by Dr. Bryce, F.G.S., amongst 

 which Mr. Tate identified Plantanus Aceroides and Sequoia Langs- 

 dorf. 



We must now refer to anothei deposit of Lignite occurring along 

 the shore of Lough Neagh. Sir Richard Griffith, in reporting on 

 this matter, says : — " The most important deposit belonging to this 

 class is situated along the south-eastern margin of Lough Neagh, 

 between Washing Bay, near Mountjoy Castle, in the County 

 Tyrone, and Sandy Bay, in County Antrim. In the County Tyrone, 

 and the northern part of Armagh, this deposit occupies a district 

 of ten miles in length by five miles in breadth, it is composed of 

 alternations of white, brown, and greenish blue clay, with white 

 and grey sand, and irregular beds of Lignite or wood coal, and, on 

 the margin of Lough Neagh, of silicified wood." Sir Richard
