Before this letter had been penned,' a committee of 

 the Council of the Society, consisting of Sir Charles

 appointed, " to consider and report upon a design for a 

 medal." Subsequently, Sir Joseph Banks, Dr. Gray 

 (Secretary), and Count Rumford, who had been chosen 

 into the Council, were added to the Committee, who, 

 on the 4th of April, 1799, delivered in a Report with 

 the following Resolution : 



" Resolved, That the device on the obverse be a tripod with 

 a flame upon it. And that the inscription round the same be part 

 of the 773d verse of the Vth Book of Lucretius (De Rerum Na- 



turd} : 



' Noscere qua vis et causa? 



41 That the inscription on the reverse be as follows: 



' Premium optime merenti ex instituto Eenj. a Rumford, S. R. L. 

 Comitis : adjudicatum a Reg. Soc. Land' 



" That the diameter of the Medal do not exceed three inches. 

 That Mr. Milton be employed in sinking the dies of the said 

 Medal." * 



The Report of the Committee was accepted by the 

 Council, and the Resolution was approved, to be carried 

 into immediate execution. But from some unexplained 



* The device on the obverse was suggested by Mr. Smirke.
