The hollow enclosing the Powerscourfc deer-park seems to have 

 contained a glacier. A little before reaching the Waterfall a bank 

 is passed which might well be the terminal moraine of such 

 glacier. This hollow, however, is at a low level. 



Mullaghcleevaun (i.e., Cradle mountain,) so called from the 

 cradle, or hollow, containing its small lake is seven miles S.E. of 

 Blesington and eighteen miles W.S.W. from Dublin ; it rises 

 2,783 feet above the sea ; the elevation of the lake being 2,244 

 feet. The damming-in moraine is sufficiently striking to be 

 indicated in the shaded Ordnance inch map, 120. 



These corries, or small cirques, like the rest among the Wicklow 

 hills (except the North and the South Prison on Lugnaculliagh) 

 face north-eastward ; a usual circumstance with such glacier sites ; 

 the reason of which is obvious on consideration. 



Pleistocene Mammcds. — As the limestone forms plain ground 

 in the neighbourhood of Dublin, with hardly any crag escarp- 

 ments except in a few stream ravines, there is but little oppor- 

 tunity for the occurrence of caves sufficient to make retreats for 

 the cave animals and to become receptacles of the bones of 

 themselves and their prey. None such, therefore, have been 

 discovered. Bones of bear have, however, been found in Co. 

 Kildare, beside the River Boyne, at about two and a half miles 

 above the bridge of the Midland Railway, 31 miles W. by N. 

 from Dublin. They were embedded in peat or sand four feet 

 below the surface. The skull is now in the Museum of the 

 Royal Irish Academy ; the rest of the bones were not preserved, 

 although they were but little decomposed. Dr. Leith Adams 

 considers that the skull is that of a }^oung female of Ursus 

 spelceus. In the same place were found many bones of deer. 



A remarkable collection of the remains of Gervus megaceros has 

 been discovered at Ballybetagh bog, parish of Kiltiernan, eight 

 miles S.S.E. from Dublin. In 1847, whilst a watercourse was 

 being cut through the bog, the heads and antlers, with other 

 bones, of about thirty individuals of this deer were found within 

 a space of 100 by 4 yards in vegetable compost and sand under 

 peat, as also one head of Cervus tarandus or reindeer with the 

 horns large and perfect. In 1875 Mr. Richard J. Moss, on further 

 exploration, discovered the remains of about fifty other indi- 

 viduals ; and since then Mr. William Williams, naturalist, has
