red. These parties showed a similar degree of blindness to the red of 

 the lime-ball-light spectrum, and neither of them saw any other colour 

 in place of the missing one, or received a luminous impression from 

 the less refrangible rays of solar or artificial light. 



From his entire observations, the author drew the conclusion, that 

 the confusion of scarlet with green, and of pink, crimson, and pur- 

 ple with blue, which characterises the colour-blind, is a phenomenon 

 of the same kind as the confusion of red with black — scarlet appear- 

 ing as green, because it is seen as yellow mixed with black — and 

 crimson as blue, because it is seen as red mixed with black. 



The author referred, in conclusion, to the observations of Brewster 

 and Dove qn the visibility of red to normal eyes, as proving that they 

 became blind to this colour in dim or unfavourable light, much sooner 

 than to blue, not to mention yellow ; so that, in the colour-blind, we 

 only see an exaggerated manifestation of a limitation of vision which 

 belongs to all eyes.
