NOTICE. 



In consequence of the increase of size and cost of the Proceedings 

 of the Academy, the subscription price from January, 1860, will be two 

 dollars annually, and the completed volumes for 1857, 8 and 9, will be 

 furnished at two dollars each, and the eight volumes previously pub- 

 lished at two dollars per volume, as heretofore. 



Under authority of the following resolutions, adopted by the Academy, 

 March 29th, and April 26th, 1859, the Committee on the Publication 

 Fund, is prepared to receive subscriptions. 



" Resolved, that the Academy will establish a permanent fund, to be 

 called the Publication Fund, the principal of which shall always be 

 kept invested in good securities, and the interest accruing thereupon 

 shall be applied to the payment of the expenses of publishing such mat- 

 ter, stated or occasional, as the Academy may think proper to issue." 



" Resolved, that every person who shall pay to the Treasurer of the 

 Academy the sum of twenty-five dollars in aid of this fund shall be 

 entitled to receive a copy of the Proceedings during life, and any person 

 who shall in like manner pay the sum of fifty dollars additional, shall 

 be entitled to receive a copy of the Journal during life." 



Your aid in establishing this fund is respectfully requested. 



Address, 



W. S. VAUX, 



Treasurer of Committee, 

 Acad. Natural Sciences, corner of Broad and Sansom Streets, Philadelphia. 



QGP* Subscribers who do not wish to continue the Proceedings at the 

 advanced rate, will please notify W. S. Vaux, at as early a period as 

 possible.
