find that the glacial period is of surpassing interest, as at Dublin 

 two mighty glacial movements converged. At the culmination of 

 the glacial epoch in Britain huge ice masses, many hundreds of 

 feet thick, were pushed forward from the Southern Highlands of 

 Scotland and the Cumberland Mountains and completely filled 

 up the Irish Sea. This glacier pushed forward and upward the 

 shells and debris of the Irish Sea and carried them high up on the 

 Dublin mountains. At a later period a great glacier which had 

 been accumulating on the north-west moved south and east and 

 converged on Dublin, and probably at the same time covered the 

 entire south. The striations of this glacier are found everywhere 

 about Dublin. Killiney Hill is marked all over with striae, and 

 the flanks of the mountains also. The boulder clay of this glacial 

 movement is much the same throughout, mainly derived from the 

 carboniferous floor over which it moved. On the other hand, the 

 boulder clay of the West British glacier contains shell fragments 

 and many kinds of northern rocks, which prove both its origin 

 and its subsequent course to have been as indicated.

" FERTILIZATION OF FLOWERS. 



The Botanical Section held their second monthly meeting for 

 the Winter Session in the clubroom of the Museum on the 

 afternoon of the 19th December, Mr. G. Donaldson presiding. 

 Mr. Sylvanus Wear gave a short address on the " Fertilization of 

 Flowers," which was very fully illustrated by an excellently 

 selected series of typical micro-slides. Mr. Wear pointed out 

 that the main object of the meeting was not so much to hear a 

 paper on this interesting topic as to enable the members to see 

 for themselves the various stages of fertilization as exhibited in 

 the specially prepared series of slides which he was about to
