OF THE COUNTY OF DOWN. 15 



nity of Moira. This feems to be a continuation of that 

 body, which, with little interruption, is to be met with 

 along the coaft, from Magilligan in the county of 

 Derry, following the headlands of the county of An- 

 trim, to that range of mountains, which run north of 

 Lifburn, and thence turning towards the weft, it is loft 

 after traverfmg the fertile grounds of Magheragall and 

 Soldierfton, in the gently Hoping hills, which overhang 

 the river Lagan between Moira and Magheralin. The 

 quarries in that neighbourhood are very near the fur- 

 face ; they confift of horizontal ftrata intermixed with 

 flints, in fome places ftratified, in others in detached 

 pieces of various forms and fizes ; it is common to fee 

 three of thefe large flints, like rollers, a yard long, and 

 twelve inches each in diameter,* ftand perpendicularly 

 over one another, and joined by a narrow neck of 

 limeftone, funnel fliaped, as if in a liquid ftate they 

 had been poured into a cavity made to receive them. 

 Shells of different kinds are found in this ftone; ,and I 

 once faw part of a rib bone exactly refembling the rib 

 of a cow, taken out of a block of this white limeftone, 

 which was as hard as marble. The marine exuvia; 

 found in hills fo many miles diftant from the fea, and 

 fo many feet above its furface, muft be a very intereft- 

 ing fubjecl of contemplation for thofe, who are engaged 

 in any of thofe philofophical fefts, that upon hoftile 



* Several are in the yard of the Society.
