The most interesting find we have to record is S. A. Stewart's 

 discovery of fossiliferous boulder clay at heights of 1300 and 

 1400 feet o.d. on Divis Mountain. Joseph Wright examined the 

 clay, which yielded 2 fry of mollusca, a foraminifer and some 

 ostracoda. Last year's report recorded the occurrence of 

 foraminifera in boulder clay on Carnmoney Hill at 450 feet, and 

 in pursuance of the agreement that investigators should when 

 possible work from Belfast Lough along the valley of the Lagan, 

 beginning at high levels and working downwards, we can now 

 (in addition to the Divis district) record fossiliferous boulder 

 clay from 800 feet at Wolfhill and 400 feet at Woodburn. The 

 prevalence of foraminifera in our boulder clay is interesting, and 

 they seem to occur whenever it is of a type to preserve them 

 from percolating water or other destructive agents. In some 

 cases, however, such as Neill's Hill, they occur in sand also, but 

 the difference in the number contained in the sandy and clayey 

 layers was striking. 



Equally interesting and significant is the occurrence all along 

 our coast line of the well-known Ailsa Craig eurite with crystals 

 of a rare blue hornblende. From this small radiant point we 

 find fragments distributed westward on Fair Head, and over an 

 area extending in Ireland as far south as Greystones, in County 

 Wicklow; in Wales, and as far east in England as Macclesfield; 

 and thickly strewn on the north coast of the Isle of Man. Last 

 summer a fragment of pitchstone was found at Island Hill, near 

 Comber, which may either be from the Island of Arran or from 

 veins in the granite of County Down. The occurrence and 

 recording of transmarine stones is specially interesting and 

 important ; nor should we omit to mention that Mr. Kendall 

 had predicted their probable occurrence in our drift. We may 

 remark in passing that he visited our district during the year, 

 and picked out of the boulder clay on Scrabo an erratic of 

 nodular basalt with which he was familiar in English drift, and, 

 subsequently, on visiting Slemish, he identified the same rock 

 upon its slopes.
