(76) HISrORT of the SOCIETY, 



Account of and without the fmalleft advantaee from the extraordinary ex- 



DrRoebuck, . • • • 1 n r i i n 



ertions and meritorious induury of her hufband. 



Dr Roebuck had, fome years before his death, been attack- 

 ed by a complaint that required a dangerous chirurgical opera- 

 tion. That operation he fupported with his ufual fpirit and re- 

 fohition. In a Ihort time he was reilored to a conliderable 

 fhare of his former health and acflivity. But the effects of it 

 never entirely left him, and feveral llighter returns of the com- 

 plaint gradually impaired his conftitution. He ftill, however, 

 continued, till within a few weeks of his death, to vifit his 

 works, and to give diredlion to his clerks and overfeers. He 

 was confined to his bed only a few days, and died on the 

 17th July 1794, retaining to the laft all his faculties, his fpirit 

 and good humour, as well as the great interefl which he took, 

 as a man of fcience and reflexion, in the uncommon events 

 which the prefent age has exhibited. 



From a man fo deeply and fo conftantly engaged in the de- 

 tail of acflive bulinefs, many literary compofitions were not to 

 be expedled. Dr Roebuck left behind him many works, but 

 few writings. The great object which he kept invariably in 

 view was to promote arts and manufadlures, rather than to efta- 

 blifh theories or hypothefes. The few eflays which he Iefi>, 

 enable us to judge of what might have been expedled from his 

 tale ts, knowledge, and boldnefs of invention, had not the ac- 

 tive undertakings in which, from an early period of life, he was 

 engaged, and the fatiguing details of bufinefs, occupied the time 

 for ftudy and inveftigation. A comparifon of the heat of London 

 and Edinburgh, read in the Royal Society of London June 29.
