208 Mr. Harvey on an Anomalous Case of Vision 



and contended that they bore no resemblance to it. The 

 darker kinds of green he considered to be brown; those of a 

 middle tone ambiguous, and the lighter kinds, as in the case 

 of emerald-green, of a pale orange colour. 



He experienced no difficulty with any of the brighter 

 varieties of yellow. From a number of pieces of different 

 coloured cloth, he immediately selected a specimen of this co- 

 lour, and a fragment of high-coloured sulphur he thought a 

 beautiful example of the same. Gallstone-yellow he conceived 

 to be orange. Wax-yellow (13), which in the vegetable king- 

 dom exists in the greenish parts of the nonpareil apple, he 

 supposed might be a green. His ideas of yellow were, how- 

 ever, on the whole very correct. 



His notions of orange were very imperfect. The common 

 marigold, he called yellow ; and a sample of fine orpiment, 

 orange ; and likewise equally choice specimens of reddish and 

 deep reddish orange he termed brown. 



Of the reds, he considered carmine, lake, and crimson, to 

 be blues; — the latter, indeed, a dark-blue, agreeing with the 

 instance of the coat before alluded to. When a great snap- 

 dragon was placed before him, he called the margin of its up- 

 per lip, which was purplish-red, a dark colour, and thought it 

 a very good match for my black coat. The part also near the 

 throat of the corolla, and which was of a light blueish-red, he 

 called light sky-blue. The yellow palate he distinguished 

 perfectly; but as that colour gradually lost itself in the pur- 

 plish-red, he gave it the name of black. He remarked, that, 

 when a boy, the ruddy cheeks and arms of the milk-maidens 

 always appeared to him of a blueish tone ; and on being shown 

 a rosy child, he persisted in the same remark. The carnation, 

 pink, and the cock's comb presented also the same appearance. 

 Scarlet-red he distinguished readily by its proper name. 

 Veinous blood* he assimilated to brown or black; and the 

 brown disk of the common marigold, and the iron-flint, al- 

 though presenting so marked a difference to the perfectly 

 formed eye, appeared to display no variety to him. To the 

 latter, indeed, he gave the name of olive. The colours of the 

 common garden rose and peach-blossom were both designated 

 lead-colour. To him, therefore, some of the sweetest and 

 most delicate colours of creation presented but little beauty. 



In the case of browns, there was much uncertainty ; in the 

 greater variety of cases assimilating them to green. Mineral 



* Mr. Dalton, in vol. v. p. 33 of the Manchester Transactions, remarks 

 that in his own case blood appears not unlike bottle-green ; and, it is 

 worthy of notice, that in the present case, it was termed " not a black but 

 nearly so."
