raised beach materials were observed, with the addition of glacial gravel 

 showing current bedding. Walking further on to Myrtleville, lower 

 " head,'' blown sand, and raised beach materials were viewed in a fine 

 section of cliff. In one of the gullies, the differential weathering of 

 sandstone and slate was well displayed. Further on again was found 

 evidence of glacial grooving and polishing, and sections showing dip and 

 cleavage. Numerous small faults were also noted along the shore of 

 Ringabella Bay. 



DUBLIN NATURALISTS' FIELD CLUB. 



Junk 25.— Irei^and'vS EvK. — Under the conductorship of J. de W. 

 Hindi the geological formation of the rocks was studied. Owing to 

 unfavourable weather conditions dredging off the island had to be 

 abandoned. A special feature of interest at this time of year was the 

 number of birds nesting on the rocks ; the north side of the island was 

 especially favourable for observing them. After a very pleasant after- 

 noon the party returned to Howth, where tea was provided. 



NOTES. 



BOTANY. 

 Cnicus pratensis in Co. Dublin. 



In his Flora of the County Dublin Mr. Colgan says of the above that it 

 has not been recently seen in the count}, but states it as his opinion that 

 further search is "likely to show that it is not yet extinct." His 

 optimism is fully justified, for it is now found to occur in considerable 

 quantity in a meadow in Gleuasmole, near St. Anne's graveyard. 

 To be more exact as to locality it occurs 300 or 400 yards to the 

 south of the graveyard. It was in July of last year I first had the 

 pleasure of happening on this handsome thistle in this locality. This 

 year, on the 12th June, in company with Mr. D. \t. Murphy, I again 

 visited the spot. The land was again under meadow, and Cnicus pratensis 

 was again noted, apparently in equal profusion. It occurs scattered 

 irregularly over a considerable area ; but in at least one spot it forms 

 quite a dense, almost circular cluster perhaps ten feet in diameter. In 

 the same meadow in fine vigour and in full bloom occurred Habenaria 

 albida in some profusion, in company with H. chloroleuca, Orchis Morio^ 

 O. maculata and the T way blade {Listera ovata.) We also got here the 

 locally rare composite Antennaria dioica.

Allium triquetrum naturalized in Co. Cork. 



This handsome southern alien has been twice recorded as occurring 

 in Co. Cork. In 1890 Mr. R. A. Phillips found some 25 plants growing in 

 a grassy hollow near Dunkettle (/. Nat., 1896, p. 167), and in 1896 Mr. W, 

 G. Axford found it farther south at Monkstown in the same county, in
