| By finding photographic materials more sensitive to the less refrangible rays, the representation of the colours of objects might be greatly improved. |
| Light is decomposed by the prism, because its component parts are refrangible in different degrees, by the same refracting medium. |
| The light of the sun consists of rays differently refrangible and reflexible. |
| Minium reflects the least refrangible or red-making Rays most copiously, and thence appears red. |
| Violets reflect the most refrangible most copiously, and thence have their Colour, and so of other Bodies. |
