however, taken in the lakes wliich lie on the peaty area, though three 

 species of freshwater beetles were found. The ground covered was of 

 special interest to the botanists, for Glenariff has long been noted for 

 the richness of its flora. The plants seen included the following:— 

 Lycopodiuvi alpinutii, L. clavotum, Hicrachun stenolepis, H. angliciun, Galiiuii 

 borcale, Arenaria verna, Drosera ang/ica, Neottia Nidus-avis^ Saxifraga 

 hypnoides, VMciniuvi Vitis Idcea, and Polypodiiim Phegopteris. The prize for 

 the best set of photographs illustrative of the geology of the district 

 visited at the previous excursion oftered by the Vice-President was won 

 by D. J. Hogg. 



JUI.Y 2.— Armagh. --Travelling by the 1.50 p.m. train from Belfast 

 the party set out on foot. Robert Bell acted as conductor. The route 

 travelled was north-west to the Carboniferous limestone quarries at 

 Carrickaloughran, then south-west to the Navau quarry, from which the 

 return was made to the Cathedral City. At Carrickaloughran the chief 

 interest of the quarry is a huge dyke of basalt over 20 feet in width, 

 which rises almost vertically through a fissure in the limestone beds, 

 cutting the nearly horizontal bedding planes of the latter almost at right 

 angles. Many fossils were collected both here and at the Navan. A 

 short distance south-west of the Carrickaloughran quarry is an extensive 

 low-level esker-like deposit of sands and gravels. It has been extensively 

 worked locally for building sand. Some interesting sections are exposed 

 in the pits from the clayey sands, in one of which a member of the Club, 

 Mr. Joseph Wright, F.G.S., recently obtained a number of foraminifera. 

 The clay bands which yield these foraminifera are intercalated with 

 laminated and current-bedded sands, overlying the whole being a series 

 of gravelly and pebbly beds, all indicating water action and current- 

 bedding. From these pebbly beds one member obtained a shell fragment 

 of arctic type. An examination of 100 pebbles or erratics, chosen almost 

 at random from a small section, yielded the following result: — Carbo- 

 niferous rock, 65; basalt, 24; mica schist, 6 ; quartzite, 4; and flint, i. 

 It is clear, then, that, though the majority of the erratics here are local, 

 yet there is a fair proportion of " travelled " rocks in the deposit, 

 Adjoining the sand pits is a rounded hill or drumlin of Boulder-clay. At 

 the Navan quarry the limestone is still extensively worked, but not 

 nearly as much for the sake of its building stone as formerly. The stone 

 is usually of a light-grey colour, though some of the deeper beds have a 

 purplish tint. Both here and at Carrickaloughran several of the beds 

 exhibit an arenaceous appearance and texture. All the beds are fossilife- 

 rous, fish remains being most prevalent at Navan. The floor of the 

 latter quarry, which is from fifty to sixty feet from the surface level ot 

 the top, is composed of hard crystalline masses of coral, the prevalent 

 type being Lithostrotion basalt i/onnis. The botanical members of the 

 party were well pleased with the result of their afternoon's ramble. 

 Raniincultis trichophylliis, only once before recorded from County Armagh, 

 was seen in a disused quarry at Carrickaloughran. On the neighbouring 

 esker the Pyramidal Orchis {Oixhis pyraniidalis') grew in the greatest pro- 

 fusion. It was likewise seen in dry pastures in another locality, and also
