the wonderfully-preserved ornament of the beautiful old door- 

 way, taken from Trinity Abbey on Lough Oughter, and now 

 built into the wall of the recently-erected church, which was 

 carefully examined and its graceful proportions admired. The 

 tomb of the famous Bishop Bedell, in the old graveyard, was 

 duly visited, and also a very fine earthen fort, with a deep 

 fosse, in a meadow adjoining. There I noted the Rough 

 Chervil {^Chcsrophylhwi temuluni), a rare plant in Ireland. 

 When the party were once again brought together, and Mr. 

 Welch had finished photographing the doorway and tomb, we 

 proceeded towards Crossdoney. Near Lisnamandra the geolo- 

 gists, under Prof. Cole, found in a field by the roadside an 

 interesting section, showing a dark andesitic intrusion, 

 baking the overlying Carboniferous sandstones, which are 

 Ijere almost horizontal. Close at hand, a gre}^ eurite appears, 

 probably an offshoot from the pre-Carboniferous granite of 

 Crossdoney. A larger rock-exposure occurs by the road- 

 side close to Crossdoney, where excellent hand-specimens of 

 the biotite-granite were obtained. Thence a short drive 

 brought us to Bellahillan bridge and the Erne, where a 

 brief halt was made. We turned northward now, and having 

 surmounted a couple of steep hills on foot, a rapid drive, with 

 lovely and ever-changing peeps of Lough Oughter, brought us 

 to Killykeen cottage, and lunch, within three minutes of the 

 appointed time, 2 o'clock. Killykeen cottage is situated on a 

 long promontory among the mazy windings of Lough Oughter. 

 Straight opposite a similar promontory, occupied by the woods 

 of Gartnanoul, projects till the lake between is narrowed to 

 the width of a stone-throw. To left and right, the water 

 extends, branching on each side among a series of wooded 

 points and grassy islands. Lunch was speedily disposed of 

 on the grassy sward by the water's edge, and then a movement 

 was made towards the boats, which had been most kindly 

 placed at the disposal of the party by Messrs. H. H. Moore, 

 W. H. Halpin, and Samuel Jones. In these the majority of 

 the party started southward to visit the ruins of Trinity Abbey. 

 A second detachment crossed to the Gartnanoul side to col- 

 lect in the woods and on the shores, while others elected to 

 explore the woods of Killykeen. On the young Aspens that 

 fringed the water on the Gartnanoul shore Mr. Kane discovered 

 the larvae of the rare moth, Cymatophora or, and a band of
