of Antrim, which have recently opened up new fields of industry. 

 The ore is always found in connexion with the Trap Rock, and is, 

 in fact, the result of metamorphism or the decomposition of the 

 trap rocks, and occur in the form of lithomarge, bole, and pisi- 

 form magnetic ores. The Islandmagee section shows the passage 

 from one into the other very clearly, and in this respect is a good 

 example of what occurs elsewhere throughout Antrim. The mine 

 at Ballypallidy is, however, an exception, for here it would appear 

 the ore has been altered, and again laid down as sedimentary de- 

 posits, in which members of the Club have for some years found 

 the remains of plants, &c, indicating a period of rest in the volcanic 

 activity during the Tertriary epoch. The iron ore of the Antrim 

 mines is, therefore, altogether different from the true iron ore of 

 the Carboniferous age, and could not like the latter be profitably 

 smelted by itself. It is, however, found very useful in reducing the 

 richer ores of England and Scotland. 



From the Iron Mines the party passed on to the " Rocking 

 Stone," in Brown's Bay, where a halt was called to talk over the 

 old stories about the evil doings of witches in this neighbourhood 

 in former days. 



The more energetic of the geological section, on leaving the 

 " Rocking Stone," betook them themselves to a bed of Lias rock 

 that crops out on the western shore of Islandmagee, some three 

 miles from the lighthouse. Ralph Tate, Esq., F.G.S., formerly 

 Honorary Secretary of the Club, has at various times carefully 

 examined this bed, and the results have been communicated to the 

 Geological Society of London, in an able paper co-relating the 

 Islandmagee Lias, with the Ammonites augulatus zone of the Lower 

 Lias. This bed yields abundance of fossils, several of which were 

 unknown to palaeontologists until described from this locality. A 

 very full list accompanied the paper referred to, and will be found 

 in the " Quarterly Journal" of the London Geological Society, 

 Nov., 1867. The working party had, on this occasion, the great 

 advantage of the assistance and guidance of Mr. Tate, and they 

 succeeded, by dint of perseverance and hard hammering, in securing 

 representatives of a considerable portion of the large assemblage of
