Your Committee wishes to thank the authors on behalf of the 

 members for these interesting communications. 



The Fiftieth Anniversary of the foundation of the Club occurred 

 in June. It had been intended to mark the event by some cele- 

 bration, but it was felt by many that in the circumstances of the 

 war such a course would not be appropriate. The President at 

 the Ordinary Meeting on the 22nd, however, called the attention 

 of the members to the event ; a full account of the proceedings 

 appears in the Journal for November. In November the Presi- 

 dent gave an address on Sponges — the first of a series of short 

 addresses which he is kind enough to propose to deliver at inter- 

 vals during the session. Material for distribution, that the 

 members might follow out the subject by making their own pre- 

 parations, was also provided by Professor Dendy. The Gossip 

 Meetings have not only been well attended, but there has been 

 almost no diminution in the number of objects of interest ex- 

 hibited, and in the enthusiasm of those displaying and explaining 

 them. The Committee thank those who, often at considerable 

 personal trouble, have done so much to render these meetings a 

 success ; and would press upon all those able to do so the desira- 

 bility of their taking part in the good work. 



The new catalogue of the Library issued to the members in 

 1915 has no doubt helped to maintain and increase an interest in 

 the Library, with the result that 160 volumes have been issued to 

 the London members, during the year. The arrangements made 

 to post books to country members have not been taken advantage 

 of, only one application having been received since the scheme 

 came into force. To give members an opportunity of ready access 

 to those books, available for reference only, a selection of such 

 works has been placed on the table on Gossip nights for examina- 

 tion, and this arrangement, which has been much appreciated, 

 will be continued in the future.
