Biographical Sketch, (rf the late Dugald Stexvart, Esq. 203 



which Sir Henry Raeburn has well preserved in his portrait of 

 him painted for the late Lord Woodhouselee before he had 

 reached his 55th year. * Mr Stewart had the remarkable pe- 

 culiarity of vision which made him insensible to the less re- 

 frangible colours of the spectrum.-j: This affection of the eye 

 was long unknown both to himself and his friends, and was 

 discovered from the accidental circumstance of one of his fa- 

 mily directing his attention to the beauty of the fruit of the 

 Siberian crab, when he found himself unable to distinguish 

 the scarlet fruit from the green leaves of the tree. 



Mr Stewards name honoured the lists of various learned 

 academies. He was one of the members of the Philosophical 

 Society of Edinburgh at its incorporation with the Royal So- 

 ciety in 1783. He was a fellow of the Royal Society of Lon- 

 don, an honorary member of the Imperial Academy of Sci- 

 ences at St Petersburgh, a member of the Royal Academies of 

 Berlin and of Naples, of the American Philosophical Societies 

 of Philadelphia and Boston, and honorary member of the 

 Philosophical Society of Cambridge. 



Besides the works which we have mentioned in the course 

 of this notice, Mr Stewart published his Outlines of Moral 

 Philosophy^ which appeared in 1793, and which he used as a 

 text-book. This work has been recently translated into French ; 

 and it has been used as a text-book in several Colleges in 

 America. He was also the author of two eloquent pamphlets 

 on a local controversy now sunk into oblivion. He had laid 

 down the resolution of never publishing any thing anonymously, 

 and we believe he never deviated from so excellent a rule. 



Before closing this brief sketch, we cannot withhold from 

 our readers the following admirable observations on the philo- 

 sophy of Mr Stewart, pronounced at the anniversary meeting 

 of the Royal Society of London on the 1st of October 1828, 

 by their distinguished president, Mr Davies Gilbert. 



" And here I would call your attention to the loss sustain- 



• At a much later period Sir Henry painted another portrait of Mr 

 Stewart, and Mr Wilkie still more recently executed a striking? likeness of 

 him in black lead. Mr Joseph has also completed a bust of Mr Stewart 

 with his usual talent.
