Here tlie proofs of his activity, enterprise, and philosophic 

 Qcuteness, and particularly of his taste for improvements in mili- 

 tary attairs, were so numerous, tiiat he began to attract more 

 public attention than before, and oflers v. ere made to him of pre- 

 ferment in foreign senice. He at length accepted a flattering in- 

 vitation given to him by the reigning duke of Hnvaria^ and went 

 into his ser\ice in 17S4. By this prince he was made lieutenant- 

 general of horse, and soon rendered himself conspicuous by intro- 

 ducing a new system of order, discipline, and economy among the 

 troops mider his command. He remained a number of years in 

 Bavaria, where he was much distinguished by his successful exer- 

 tions to destroy mendicity, and to meliorate the condition of the 

 poor ; and by a variety of improvements highly favourable to ma- 

 nufactures, economy, and humanity. On leaving the scr\-ice of 

 the elector he was created a count ; his title being taken, by his 

 own choice, from the name of the town in America in which he 

 iiad for some time resided. 



Count Rumford has chiefly resided, for a number of years past, 

 in Great Britain, where he has been so much celebrated for his 

 experiments, discoveries, and improvements in militar}', economi- 

 cal, and chemical science, that it is unnecessary to dwell on his 

 merits. Beside the new light which he threw on the subject of 

 gunnery J before mentioned, the friends of science and humanity are 

 indebted to him for improved methods of constructing chimnicx 

 and stoves; for important discoveries and improvements relative to 

 cookery and aliment; for curious and highly interesting experi- 

 ments on heat ; &c. In short, it seems to be generally agreed, 

 that he stands in the first class, if not at the head, of all the 

 practical, and particularly the economical philosc^ihers, now 

 living. 



He was knighted by the king of Great Britain in 1/S4, and has 

 received many honourable tcstimoiiies of public and private re- 

 spect in that country. His only child, a daughter, now resides in 

 tlie town of Boston.
