held in Trust for the same purposes and on the same conditions as the original 

 donation. 



I believe it was the intention of my late Brother Thomas B. Wilson, to have 

 made a bequest to the Society, but his last illness was so very violent and rapid 

 in its course, as to deprive him of that power; therefore, in making this dona-

 but to the memory of his greatness and worth. Yours respectfully, 



RATHMELL WILSON. 



On motion of Mr. Pine, the thanks of the Society were tendered to 

 Rathniell Wilson, Esq., for his generous donation, made this evening,
