again reached near Drumuareagh Port. Beyond this the road showed 

 the effects of recent landslips, large masses of freshly slipped Chalk and 

 Lias being noticeable on each side of the road. At Glenarm the various 

 places in the neighbourhood of the town were visited. 



DUBLIN MICROSCOPICAL CLUB. 



ApriTv 9. — The Club met at Leinster House, 



Mr. M*Ardi,E exhibited Cephahzia pallida Spruce, which was collected 

 by himself aud the Rev. Canon Lett at Pontoon, on the shores of Lough 

 Conn, Co. Mayo, in May last year. The specimen of this minute liver- 

 wort was in fruit; the perianth is very fragile, composed of a single layer 

 of cells; the capsule oval,, dark-brown, with pale-yellow spores and 

 bispiral elaters. The plant was found many years ago by the late Dr. 

 D. Moore on the shore of Lachan Bay, in the same county ; It has also 

 been collected on the Hill of Howth, Lough Bray, Co. Wicklow, on Mount 

 Brandon aud other stations in the Dingle peninsula, by Mr. M'Ardle. 



Dr. Pethybridge exhibited slides and pure cultures in plum-gelatine 

 of a fungus found growing in the leaf-sheaths oi Dadylis glomerata. The 

 organism first attracted attention on account of its pink colour ; this is 

 due to a pigment contained in solution in the cells of the septate 

 mycelium, and in the cultures it appeared to be formed only in the 

 liyphse living in the substratum, the aerial hyphse being white. No 

 satisfactory solvent for the pink colouring matter had been found, nor 

 had the fungus produced spores or conidia of any kind, so that it was 

 not possible to identify it. 



May 14.— The Club met at Leinster House. 



Mr. Moore showed hooks from fruits of a species of Loasa, probabl}- 

 Z. lateritia. The outer surface of these fruits is covered with fine hairs, 

 shaped like a mushroom anchor, along the margins of which are many 

 strong hooks or teeth, pointing downwards. The stalks of these hairs 

 are beaded, and each segment has a hook pointing downwards. These 

 hooks catch firmly any object they come in contact with, causing the 

 fruits to be carried about by animals, and so enabling the seeds to be 

 spread about. 



Mr. M'Ardi^E exhibited portion of the frond of Metzgeria hamata, Cnid- 

 berg, the largest of the genus which is found in this country, and easily 

 separated from all others by the long marginal hairs which are divaricate, 

 hooked, deflexed. The female fruit has not been found on Irish speci- 

 mens. Those exhibited bore antheridia, and were also interesting as 

 showing how the plant reproduces itself by the process of budding. 

 They were collected at Tore Waterfall, KiUarney, in 1877 ; the plant is 

 frequent in the mountainous parts of the Dingle peninsula, Co. Kerry, 

 and in similar situations in the Co. Mayo. It has recently been collected 

 in Ben Vorlich ravine, in the district of Lough Lomond, Scotland, by Mr. 

 Macivar, and is well known in the tropics and sub-tropics.
