Craig lie a little to the south, and behind these the Ayrshire coast 

 is faintly seen, uninteresting in general but broken here and there 

 by prominent features, such as the " False Craig." 



The Geology of the Torr area is strikingly different from that 

 of the rest of Antrim. Here the Chalk rests directly upon the 

 Pre-Cambrian schists, the oldest rocks in Ireland, which rise to a 

 height of nearly a thousand feet. To the south the basaltic cap 

 of Carnanmore still overlies the Chalk, but over the greater part 

 of the area this rock has been completely worn away. Encircling 

 the greater part of Torr Head itself is a band of Primitive limestone 

 some 20 feet thick, which at the extreme point is faulted down. 

 Large blocks of gneiss were also found, but this rock, which so 

 closely resembles some of the coarser schists, was not seen in situ. 

 The prevalence of boulders of a red granite, possibly of Scotch 

 origin, may also be worth mentioning. The botanical members 

 had a busy day, and most of the expected plants were seen. 

 These included Vicia syivatica, Epilobium an^ustifolium, Saxifraga 

 aizoides, S. kypnoides, Parnassia palustris, Geranium lucidum, 

 Empetrum nigrum, Cy stopfer is fragilis, Draba incana, and Arabis 

 liirsuta, while Sisymbrium Thalianum and Erophila vulgaris were 

 added to the list for this locality. Of the Mollusks only Arianta 

 arbustorum is worthy of mention ; this species which occurs in 

 several spots near the village of Torr, being observed by the 

 Botanists in great plenty among the " Alpine " plants along the 

 Chalk escarpment. The Primitive limestone at Torr Head is, in 

 parts, riddled with " Helix-borings," in this case Helix nemoralis 

 being responsible for the phenomenon. From the large numbers 

 of young examples of this shell observed in the borings, it would 

 almost appear as if a pilgrimage from the surrounding schists had 

 taken place, during this, the season of growth, the lime being 

 essential for the purpose of shell-making. Only two common 

 species of Woodlice were observed, but several Millepedes and 

 Centipedes, a hitherto neglected group, were collected, the 

 common Stomius marginala, Julus albipes, and a species of
