 papers published by it on individual orders, which arrangement is of material benefit to 

 the student who desires promi)tly 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 papers relating to individual orders or subjects has been 

 developed by the Society. Information concerning these arrangements supplied upon 

 apijlication.
