The sensation of colour on the eye is very different in different persons; many persons having an acute sense of vision readily perceive the qualities of objects but are incapable of judging about the agreement or disagreement of particular colours, and when the faculty is small they confound them and are incapable of perceiving their effect. When prominent the individual possesses a taste for gaudy colours, careless about their arrangement or harmony with others. It is situated in the centre of the eyebrow giving it a prominent aspect such as may be witnessed in the portraits of Titian, Rubens, and many celebrated artists: The organ of colour well developed gives harmony and excellence in colouring and is useful to botanists, dyers, mercers, and all artists: That the faculty is abused, or rather wanting may be witnessed by the numberless facts that we meet with constantly, where people dress in gaudy colours and appear quite regardless of their being suitable or otherwise. 16. SPACE. This hardly appears a positive faculty, we have noticed it from its being mentioned by phrenologists; it appears to be of a similar kind to form, size, and weight, all of which organs are connected with the organ of vision; the persons who have the organ well developed are persons of wide views in every thing, they are enraptured with extensive prospects, mountains, and every thing of a large size--if proved to exist, such a faculty would be valuable to painters. 17. ORDER. The tendency of this faculty is to produce a love of order and arrangement in every thing; they are distressed by confusion, and are highly pleased with a regular arrangement of their furniture, books and other property. The organ is located in the superciliary ridge, and from its general small developement, much fact is still necessary before the organ and its value can be definitely determined: there is certainly well marked in some persons, a love of order, and in others a carelessness to disorder, the one often degenerating into precision in trifles that produces great discomfort to other persons, the latter often inducing a disregard of necessary care and attention: the medium is to be sought for by all who detect either in their own character. 18. NUMBER. The organ of the faculty of NUMBER is situated above and outside the external angle of the eye, a little below the external angle of the frontal bone. The special function seems to be calculation in general: it does not seem to extend to any faculty of computation beyond that of numbers, although from the tact that it associates with it, it facilitates the study of mathematics. Many instances are adduced of its large size in good calculators, particularly in George Bidder, the calculating boy. This organ, like the other perceptives requires cultivation. 19. TUNE.
