appropriate crayons in regard to tint, whilst I exercised my own 

 judgment in regard to tone; if, as lias often been done for experi- 

 ment, what others call a red crayon is given to me, whilst executing 

 the foliage of a tree, provided it suited my ideas of depth, I have 

 never distinguished the difference, and have now some drawings with, 

 lam told, bright red intermixed in the foliage; and in one instance 

 a sea piece has light pink crests to the waves. I selected these my- 

 self, the assorted crayons having become intermixed. * * * 

 I remember the late Lord V joking his wife for wearing a scar- 

 let dress ; she assured him it was bright green ; and on comparing 

 notes with him, I found that our defect of vision was precisely the 

 same, although he had been scarcely aware of it until that time. — 

 My brother, when a child, once picked up a red-hot coal, asking 

 'what that funny green thing was?'" 



Strange as it seems, Dr. Wilson gives us several instances of ar- 

 tists suffering from this defect. The brother of Admiral 



once painted a red tree in a landscape without being aware that he 

 had done so : Dr. S. says he has done the same : one artist-pupil 

 copied a brown horse in bluish-green, painted the sky rose-colour, 

 and roses blue : another painted a head with a face muddg-green, and 

 insisted on a packet of emerald-green being vermilion. 



Rather awkward it must have been for Admiral when he 



1 chose a pair of green trowsers once, thinking they were brown :' 

 and still more for those members of the Society of Friends of whom 

 we read 'one provided himself with a bottle-green coat, intending to 

 purchase a brown one ; and selected for his wife, who desired a dark 

 gown, a scarlet merino. Another, who is an upholsterer, purchased 

 scarlet for drab, and had to rely upon his wife and daughters to se- 

 lect for him the fabrics needed in his profession !' Most of all should 

 we sympathise with that unhappy Minister in the same sober commu- 

 nity, who selected scarlet cloth as material for a new coat. In little 

 better case was that officer of the navy who purchased ' a blue uni- 

 form coat and waistcoat with red breeches to match,' or the under- 

 taker's apprentice, who 'on being sent for black cloth to cover a 

 coffin, brought scarlet ;' or those journeymen tailors who ' matched 

 the scarlet back of a livery waistcoat with green strings ; put a ruddy 

 brown side by side with a dark green ; informed a purchaser that a 

 red and blue stripe on a piece of trowser-cloth was all blue, and put 

 a crimson patch on the elbows of a dark-blue coat.' 



It is certainly curious that colour-blindness should thus be found 

 in professions where we should least expect it : thus, says Dr. Wil- 

 son, ' dyers, painters, weavers, clothiers, and the members of other
