TO accommodate tlie purcliaser; and to invite communications, the Academy has 



^ 



thought it expedient to publish its Memoirs In the present form. In the choice of pa- 

 pers, the Committee, to whom the selection was entrusted, have studied utility, variety, 

 and entertainment. As communications increase, new publications will appear. And 

 it is to be hoped, that a regular series of numbers will call the attention to philosophical 

 inquiries ; and shew, that the Academy does not overlook the end of its Institutlon- 

 The reader will remember, that the Society is not responsible for any communications, 

 which may be selected and published. They must stand or fall by their own merit. 

 The mathematician must answer for his own reasonings, the philosopher for his experi* 



ments, and the theorist for his conjectures.
