OF ARTS AND SCIENCES: NOVEMBER 14, 18G5. 61 



scientific honors which you have worthily won ; and with them, if it 

 may be so, the full recognition of the rights, and possession of the 

 advantages, which pertain to your inventions. 



On receiving the medal, Mr. Treadwell expressed his ac- 

 knowledgments as follows : — 



Mr. President and Gentlemen of the Academy : — 



I receive with great satisfaction the Rumford Medal which, in ac- 

 cordance with a vote passed at the Annual Meeting, you have now pre- 

 sented to me. I prize this premium the more as coming from this body, 

 with which I have been intimately associated for more than forty years 

 as an active member, and for a very large part of the time as an office- 

 bearer. I may be permitted to say, however, that, although I am sen- 

 sible that I am indebted for this award in a large degree to your kind 

 partiality for an old associate, which turned your attention to his labors, 

 yet it was made not only without any application on my part, but your 

 motion towards it was wholly unknown, and not even thought of by 

 me, until the vote of the Rumford Committee was communicated 

 to me. 



The award was, as stated in your vote, (which uses the language 

 of Count Rumford,) for " improvements in the management of heat." 

 But as this management of heat was incidental to, and intimately con- 

 nected with, improvements in the construction of cannon, to which I 

 had given yeai'S of labor, you have extended your examination into 

 the character of those improvements generally. For the very thorough 

 research which it is evident you have made into the whole subject, I 

 feel under great obligations to you ; and the very favorable conclusions 

 which you have reached, and which have been so fully and kindly ex- 

 pressed by you, Sir, as to the originality and value of my researches 

 and labors, form an additional source of satisfaction to me. This, 

 taken alone, would constitute one of the most welcome recognitions and 

 rewards that could be given to me. Permit me, in conclusion, to 

 express my special obligations to the members of the Rumford Com- 

 mittee for directing their attention to my labors, and for the very favor- 

 able view which they have taken of their merits. 



The President then introduced Dr. Burt G. Wilder, who 

 presented the following communication ; —
