first eruptions produced rhyolite, a lava rich in silica. Illustra- 

 tions were given of the remarkable volcanic phenomena of 

 Co. Antrim, including the contraction-structure of the cooling 

 lavas to which the features of the Giant's Causeway are due. 

 The dykes of Cave Hill were also discussed. Mammals had 

 now, in Eocene times, taken the place of the huge and less 

 intelligent reptiles ; and later, in Pliocene and Post-Pliocene 

 times, the hippopotamus and the elephant wandered in this 

 country. The glacial phenomena pointed to a recent cold 

 period, probably accompanied by partial submergence beneath 

 the sea ; but man came into the country as the land a^ain rose, 

 and at Lame elevation has gone on to a height of 20 feet since 

 his appearance, flint implements occurring in the raised sea 

 beach at the Curran station. The history of the county shows 

 that vast changes are in every probability still in progress ; but 

 the story of life on the globe gives one every confidence that 

 man and his successors will live on and go forward in new 

 lands, even though Co. Antrim or all Europe ultimately sink 

 again beneath the sea. The lecture, which lasted about an 

 hour and a half, was illustrated by some eighty photographic 

 slides of local features, which were almost entirely the work of 

 R. Welch, who officiated with his usual generosity at the 

 lantern. 



After the lecture was delivered, the audience having heartily 

 applauded, 



The President said it was a great source of satisfaction to the 

 Club in having successfully carried on such an instructive and 

 interesting course of lectures, and being favoured by such a 

 capital lecturer as Professor Cole. From lecture to lecture the 

 interest and the attendance had increased in a most gratifying 

 way to all concerned, and he felt quite sure that the present 

 success would lead to new courses of lectures being delivered 

 next winter either by Professor Cole or some other equally 

 competent lecturer. 



F. W. Lockwood, C.E.; J. J. Phillips, C.E.; Mann Harbison, 

 and Dr. Sheldon having expressed themselves pleased and well 

 satisfied with the whole course,
