158 THE Rey. MAXWELL H. CLOSE, 
The hollow enclosing the Powerscourt 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 8.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 Mammals.—As the limestone forms plain ete 
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 haye, 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 young female of Ursus 
speleus. In the same place were found many bones of deer. 
A remarkable collection of the remains of Cervus megaceros has 
been discovered at Ballybetagh bog, parish of Kiltiernan, eight 
miles $.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 REN 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
