Separates of papers published in the Proceedings and Transactions, if not out of print, 
can be supplied at prices given in our jirice lists, which are sent upon apjilication, stating 
order or orders desired. The Society has also inaugurated a system of subscription to 
papers published by it on individual orders, which arrangement is of material benefit to 
the student who desires jiromptly the literature on any special group, but who does not 
desire to subscribe to entire volumes of the Transactions. A method of notification of the 
appearance in its publications of pajiers relating to individual orders or subjects has been 
developed by the Society. Information concerning these arrangements sup})lied upon 
application.
