564 ISLE OF MAN. GEOLOGY. LIMESTONE. 



In this case the passage of the vein is not connected 

 with any change from the stratified to the unstratified 

 limestone ; since the former is found lying on both sides 

 of it. At some little distance from this vein it however 

 ceases, and is replaced by the unstratified, which prevails 

 along the remainder of the shore towards Kintracht, where 

 it terminates. 



The works of the quarry have laid open the junction 

 of the black strata and the trap. They are here found 

 firmly united ; a disturbance also taking place in the beds, 

 but extending to a distance of two or three feet only from 

 the planes of contact. 



A more remarkable change is visible where the super- 

 incumbent breccia and the limestone meet, and this 

 change, as far as I could trace it, seems limited to the 

 neighbourhood of the trap. In other places the breccia 

 seems evenly disposed on the plain surface of the lime- 

 stone ; but here, the latter is elevated into ridges, undu- 

 lations, and acute points, the former adapting itself 

 to them. In different places also, fragments of the lime- 

 stone are entangled in the breccia, and processes re- 

 sembling short veins rise from it and traverse that rock. 

 All these circumstances seem to bespeak some disturbance 

 since the breccia and limestone were deposited. The 

 pseudomorphous veins are similar in their characters to 

 those formerly noticed in treating of Isla, and are doubt- 

 less to be attributed to analogous causes. It is unneces- 

 sary to make any further remarks on the phenomena 

 ^attending the passage of the veins, excepting as far as the 

 unstratified limestone is concerned ; since nothing new 

 can be added on a subject concerning which so much 

 has already been said throughout this work. 



In reviewing the whole of the preceding facts which 

 relate to the stratified and unstratified limestone, the 

 following conclusions seem to be among the most inte- 

 resting. 



The whole limestone mass, whether stratified or unstra-
