Aprii, 2. — Mr. J. E. Palmer in the chair.— Dr. S. H. Pethybridge 

 read some "Notes on the correlation between Plant-structure and Plant- 

 habitat." A paper by Mr. J. N. Laird on the occurrence of Galena and 

 Calcate in Carboniferous Limestone was communicated by the 

 .Secretary (Dr. Patten). 



May 4. — Excursion to PorTraine. — The first excursion took place, 

 the venue being Portraine. A party of twenty-four members and visitors, 

 under the conductorshipof Mr. H.J. Seymour, left Amiens-street by the 

 1.50 p.m. train for Donabate, and walked down to the shore below the 

 Coastguard Station, A halt was made here, during which the conductor 

 gave a short account of the geological structure and peculiar interest of 

 the locality. The party then walked along the shore, and the conductor 

 pointed out and explained in detail the various points of geological 

 interest which had been referred to just previously. Some good 

 specimens of barytes, which occurs in veins in the andesitic lavas near 

 the harbour, were obtained, and also, amongst others, numerous 

 specimens of the fossil coral Halysites catenularitts from the Bala limestone 

 further south. At about 6.30 p.m. the party returned by an inland route 

 to Donabate, where tea was provided. At a business meeting held sub- 

 sequently, Dr. Pethybridge in the chair, two candidates were proposed 

 for membership. 



May 25. — Excursion to the Gi,en of the Downs. — Twenty 

 members, under the guidance of R. LI. Praeger, travelled by the 1.45 train 

 to Greystones, and drove thence through Delgany to the Glen of the 

 Downs. They then moved through the wood to the " View Rock," on 

 the western side of the Glen, where an excellent survey of the scenery 

 and geology of north-eastern Co. Wicklow was obtained. Egg cocoons 

 of the scarce local spider, Ero furcata, were found hanging beneath the 

 loose stones of the walls on the way up, while among the crags near the 

 summit the White Beam Tree (Pyrus Arid) was noticed, and here un- 

 doubtedly native. A descent by glissading over the vast beds of the Great 

 Wood Rush {Luzula sylvaticd) was made, and the party returned on foot 

 to Greystones by way of Killincarrig. After tea, the 8.45 train was taken 

 back to town.
