his copper mines near Pheenixville, and laid on the table 
for publication in the Proceedings “ Descriptions of extinct 
Vertebrata from the Permian and Triassic formations of the 
United States, by E. D. Cope, a part of which was a MSS.

Professor Marsh inquired what authority the Society 
assigned to the dates of publication affixed to its extra cop- 
ies of papers in the Proceedings distributed by their authors, 
and how such dates were fixed, urging the importance of 
established and well understood rules for the government of 
the practice in such eases. 
Atter much discussion, it was, on motion of Mr. Lesley, 
‘« Resolved, That the Secretaries be directed to use, in case of separata 
or extras, and at the foot of the last page of the same, the phrase ‘ Printed 
(such a date)’ viz: the date of the day of the completed printing of each 
memoir.”’
