Notice to Contributors of Memoirs. — Authors are reminded that, under an 

 arrangement dating from 1871, the acceptance of Memoirs, and the days on which 

 they are to be read, are now, as far as possible, determined by Organizing Commit- 

 tees for the several Sections before the beginning of the Meeting. It has therefore 

 become necessary, in order to give an opportunity to the Committees of doing 

 justice to the several Communications, that each Author should prepare 

 an Abstract of his Memoir, of a length suitable for insertion in the pub- 

 lished Transactions of the Association, and the Council request that he will send 

 it, together with the original Memoir, iby book-post, on or before August 1st, 

 addressed thus : — " General Secretaries, British Association, 22 Albemarle Street, 



London, W. For Section " Authors who comply with this request, 



and whose Papers are accepted, will be furnished before the Meeting with 

 printed copies of their Reports or Abstracts. If it should be inconvenient to 

 the Author that his Paper should be read on any particular days, he is requested 

 to send information thereof to the Secretaries in a separate note. 



Information about local arrangements may be obtained from the local Secre- 



G. GRIFFITH, Assistant General Secretary.
