NOTICE. 



Members qualified to vote at the elections of the Society, 

 Societies in correspondence with it, and Subscribers for its 

 Transactions, are entitled to receive copies of the "Proceed- 

 ings" at the times of their publication. Others desiring to re- 

 ceive them, are respectfully informed that the subscription 

 price has been fixed at one dollar per annum, to be always re- 

 mitted to the Treasurer in advance. 



Those copies which are intended for distribution in foreign 

 countries, will be transmitted in such manner as may be indi- 

 cated by the parties to whom they are addressed: those for 

 Philadelphia and other parts of the United States, by the me- 

 dium of the post office. The Reporter will, however, retain 

 them, if so directed, and will attend at the Hall on Friday 

 evenings to deliver them in person. He particularly solicits 

 that every irregularity occurring in the distribution may be 

 communicated to him promptly, as it may not otherwise be 

 practicable for him to supply missing numbers. The earlier 

 part of the first volume has been for some months out of print. 



Hall of the American Philosophical Society, 

 Philadelphia, 26th June, 1841. 



Erratum — In No. 17, at page 43, in the fifth line, for "produce," read "precede.'
