yields such a deep purple dye. One evening after dinner a 

 party, mainly ladies, visited the caves of Muslac, the long cave 

 being lighted with candles, this party noticing the great folds 

 and contortions of the massive beds of quartzite of which the 

 Muslac Cliffs are composed ; the fine folds, very close together, 

 of the schistose rocks at the ladies' bathing cove were also 

 examined; and a volcanic sill, a long narrow mass of basalt, 

 either interbedded with the metamorphic rocks or intruded 

 among them at a later period. This latter being fairly typical 

 of many intrusions on Rosguill. 



The strands along Mulroy had fine patches of small 

 shells, among which Rissoa and Odostomia were plentiful, and 

 some members who crossed the Mulroy entrance to " Fanad- 

 between-the-Waves " found little wind-blown pockets of 

 these, with Foraminifera, and many small beetles, plentiful 

 on the dunes of Doaghmore Bay, far away inland from the 

 tide-mark. Later some thick masses of marine shells were 

 examined in the rock-gullies at Muslac; also the habitat of 

 Otina Otis, a rare shell recently found in shell debris on the 

 strand. At Ray Wood some members were fortunate enough 

 to find some very rare or very local species of land-shells, in- 

 cluding Limax cinereo-niger, about which a keen controversy 

 lately raged, the exquisite little Helix lamellata, Hyalinia 

 excavata, and white or hyaline colonies of other good or com- 

 mon species; this locality would evidently well repay further 

 investigation. 



LARNE HARBOUR. 



(Half-day Excursion.) 



The fifth excursion of the season took place on Saturday, 

 1st August, when over fifty members and friends assembled at 

 Larne Harbour on the arrival of the 2-15 train from Belfast. 

 The majority came by that train, but many members were 

 staying at Larne Harbour just then. The chief object of the
