A compact little collection under the departmental title of 

 " Marine Life " comprised a number of books illustrative of 

 marine life, lent by the Free Library, and some models of 

 marine life, lent by the Queen's College. Henry Hanna, a.m., 

 showed a collection of invertebrates and a clever series of slides, 

 for which the club's prize had been awarded, while some 

 seaweeds collected on last season's dredging excursions were 

 exhibited by Professor Johnson and Miss Hensman. Professor 

 A. C. Haddon contributed some examples of commensalism 

 anc symbiosis from the marine fauna of Ireland and other 

 countries ; and Mrs. J. T. Tatlow had a collection of seaweeds 

 collected at Roundstone, Connamara, and a comprehensive 

 series of shells collected on Magilligan Strand, County Deny. 

 The conchological section comprising the above and the 

 collection of land shells by R. J. Welch was one of the finest 

 ever shown in the club, and one which attracted attention. 

 Near this was the table of A. G. Wilson (honorary secretary) 

 displaying rocks and miscellaneous objects of interest, including 

 specimens of Irish fresh water pearls and the pearl mussel {Unto 

 margaritiferd)) the shipworm, with samples of its destructive 

 power, and some primitive forms of lamps. Dr. C. Herbert 

 Hurst had also a collection of marine life objects. The geological 

 exhibits comprised photographs of features of the high Alps, by
