with regard to Colours. 255 



no difference, although the former had a greyish, and the latter 

 a greenish hue. Between raven and fine velvet black he could 

 perceive no difference. His master furnished me with the fol- 

 lowing fact. Being desired to repair an article of dress that re- 

 quired black silk, he employed crimson ; and a similar mistake 

 occurred on two other occasions. 



Both indigo and Prussian Blue (24. and 25. of SYME) he re- 

 garded as black. China and azure blue (26, 27. ibid.) he con- 

 sidered to be blue, but thought them good matches for carmine- 

 red (90.), when placed by its side. Ultramarine blue (28.), he 

 thought to be the same as lake-red ; and when a light lake-co- 

 loured wafer was laid on a piece of azure-blue cloth, he thought 

 the resemblance very perfect. Flax-flower blue (29.), he could 

 distinguish as blue. His master informed me, that he once con- 

 founded sky-blue with green when repairing some article of 

 dress ; and on another occasion, when a young gentleman's dark- 

 blue coat was brought to him for immediate repair ; the mother 

 of the lad was surprised to find the elbow of the coat repaired 

 with crimson *. 



SYME'S Purples he regarded in general as blues ; the only one 

 to which he could perfectly adapt his notion of that colour, be- 

 ing the imperial purple (39.) of a specimen of fluor-spar. To 

 the pale blackish purple, the colour of the porcelain jasper, he 

 would only give the name of dark colour. A blue lilac he called 

 a lead colour ; nor could he trace a shade of purple in the sweet- 

 scented violet, or in a plum. From all the information I could 

 obtain, he regarded purple as a slight modification of blue. 



Greens were to him a source of much embarrassment. On a 

 particular occasion, I requested him to bring me eight or ten

 " Navy, and, several years ago, he purchased a blue uniform coat and waistcoat,.
