DUBLIN NATURALISTS' FIELD CLUB. 



May 8. — -Excursion to Sutton and Howth. — The first place visited 

 was Bottle Quay, where the Dolomite beds were examined and their origin 

 explained by J. de W. Hinch. From a point of vantage near the tram road 

 the old hore line along the bay was pointed out and its relation to the 

 raised beach discussed. The recent appearance of the North Bull above 

 high-water mark received notice. At the summit the general geology of 

 Howth was demonstrated by the Howth quartzites and the intercalated 

 grits and slates. The latter portion of the excursion was marred by very 

 heavy rain. 



May 29. — Excursion, Old Conna Hill, Bray, by kind invitation of 

 Capt. Riall. — The members, about twenty-five in number, were enter- 

 tained to tea by the Misses Riall. The gardens, which are in a fine state of 

 cultivation, with numerous shrubs and flowering plants, were first in- 

 spected ; and afterwards a walk was taken around the pinetum. A large 

 number of species of conifers are represented by fine trees, notably Pinus 

 ponderosa, P. insignis, P. Montezumae, P. Cembra, Picea Morinda, Tsuga 

 Albertiana, and Libocedrus decurrens. The most interesting species seen 

 were Taxodiurn mucronatum, a native of Mexico, which differs from the
