On the upturned blooks I have examined thousands of these jointed stems, 
some eight, ten, and twelve inches in length ; and though I have been able to 
detect what appears to me to be the roots, in situ, I have never yet been 
fortunate enough to obtain a specimen of the beautiful " cap-like" body of 
Ci/athocrimis, or the more ornamental E/icrimis raoiiiUfonais. There are several 
kinds of sea-lilies in the ^Mountain-limestone ; and they range throughout the 
greater part of the paleozoic and secondary ages of our world's history. 
Their entombed remains form a large portion of the solid- work of our globe ; 
and palaces, castles, churches, and huge bridges are being, and have been 
constructed of the rocks formed of their stony skeletons. The works of man, 
alas ! are_ puny and insignificant compared with the mountain-accumulations of 
the Encrinites of the ancient seas. 
The Mollusca of the Kil Toom bed differ in no respect, so far as I am acquainted 
with them, from the Moluscaof the Mountain-limestone generally. I will not, 
however, speak positively on this point. TerebraUiUe, Spirifers^ 2ixA Produdi 
I have seen in situ; but specimens are very difficnlt to get, owing to the hard- 
ness of the stone. There are other fossils besides those I have named. 
Mountain Limestone, Kil Toom. The stone crops out on a level with the road. 
Strike north and east. Dip east. Angle about 28 degrees. Depth 50 feet. 
The next quarry of any note in the vicinity of Athlone is situated at Coorsau 
Point, on the eastern border of Lough Ree. There are two roads leading to 
the quarry : one by the river, through the village of Coorsan ; the other by a 
house called — from a peculiarity in the architectural design — " Weligan's foliy." 
The geological tourist shoidd take the latter. Between the town and the lake 
many interesting sections of rocks belonging to the Drift-era will be observed 
on either side of the road. Huge boulders of Mountain-limestone, several 
tons in weight, lie scattered over the plains on either hand. At one particular 
spot, about midway between the town and the lake, it would be no unprofitable 
study if the tourist halted for an liour to examine the position of those boulders, 
how they rest upon the stratified stods and gravels, and how the atmosphere 
has made sad havoc v\ith their exposed surfaces. These boulders may at one time 
have belonged to the Coorsan bed ; but of tliis I should not like to speak 
positively. 
In several of the smaller boidders I liave found OHhis resupiiiata, and 
Huomphalus pentangidata in company with Si/ri/igopora reticulata. Now I have
