Deposits containing Fossil Plants. 79 



Ireland (120 miles west of Dublin). 

 (Reid, 'The Origin of Megaceros-marl,' Irish Natu- 

 ralist, May, 1895.; 



A sample of the marl which yields the skeletons of 

 the Irish elk was sent to me by Mr. W. Williams of 

 Dublin. The exact locality was not stated. The deposit 

 is a Chara-marl full of seeds of Pond-weeds, with a few other 

 plants. 



Ranunculus aquatilis. Eleocharis palustris. 

 Myriophyllum spicatum. Carex (?). 

 Littorella lacustris. Scirpus (?). 

 Potamogeton crispus. Chara (several species). 

 praelongus. 



The exact date of these marls is still uncertain, for the 

 associated deposits have not yet been properly examined. 

 Above similar Megaceros-marls at Ballaugh in the Isle of 

 Man is found peat with Salix Jierbacea. No fossil Arctic 

 plants have yet been found in Ireland, and the deposit is 

 therefore provisionally classed with the Neolithic peat- 

 mosses. 



Kelsey Hill, Yorkshire. 



(Reid, 'Geology of Holderness,' pp. 74, 75. Mem. 

 Geo I. S11 rvey . 1 8 8 5 . ) 



Peaty clay caps an isolated sand-hill rising about 40 feet 

 above the Humber marsh. The plants are : — 



Ranunculus aquatilis. Phragmites. 



Potamogeton. 



The exact age of the deposit is doubtful ; for, though 

 provisionally classed as Neolithic, it may be Late Glacial. 



Kilmaurs, Ayrshire.
