PROFESSOR COLE'S CLASSES. 



For the third time the Section has benefitted by the instruc- 

 tions of Professor G. A. J. Cole, who devoted a week to the Club, 

 conducting in the day a series of field excursions, whilst a 

 Petrographic Class of 12 students met each evening for the study 

 of rock sections and rock-forming minerals under the microscope. 

 Fine weather favoured the course, and the list of places visited 

 is appended. The evening class resembled a " special course " 

 at the Royal College of Science, and was a valuable opportunity 

 for the Section, which it is hoped may be continued next year. 

 The following is the list of his field excursions : — 



18 March— Cave Hill and Squire's Hill. 



19 ,, — Stewartstown. 



20 ,, — Dundonald and Scrabo. 



21 ,, — Sandy Braes and Tardree. 



22 ,, — Island magee* and the Gobbins. 



24 ,, — Coast near Newcastle and Thomas Mountain. 



The thanks of the Section are due to Professor Cole for 6 

 reprints of papers on Irish Geology and for the microscopic 

 examination of rock specimens, more especially those suspected 

 of containing riebeckite ; to A. M'Henry, m.r.i.a., for the 

 determination of a large number of erratics and for a copy of
