minded 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

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 published Tvansac- 
tions of the Association, and the Council request that he will send it, together 
with the original Memoir, by book-post, on or before August 12, addressed 
thus:—‘‘General Secretaries, British Association, 22, Albemarle Street,

this request, and whose Papers are accepted, will be furnished before the 
Meeting with printed copies of their Reports and Abstracts. If it should be 
inconvenient to the Author that his Paper should be read on any particular

separate note.
