Actually, no matter results exterior heat produces in external bodies, the same are produced by their internal heat in animal and vegetable organisms. As was to be anticipated, therefore, it is in the vegetable kingdom that tastes happen in richest variety. Indeed, within the earlier case additionally there is no such thing as a purpose why, to persons at a distance from the juxtaposed blacks and whites, some one color should not appear to current itself as a blend of both. But the colour which air or sea presents, because the physique by which it resides isn't determinately bounded, shouldn't be the identical when one approaches and views it close by as it is when one regards it from a distance; whereas in determinate bodies the color offered is definitely mounted, unless, indeed, when the atmospheric atmosphere causes it to alter. Any two issues can affect, or be affected by, one another solely so far as contrariety to the opposite resides in both of them. Yet, if this is absolutely so, it clearly follows that every of the opposite senses is a mode of Touch; but one can see at a glance that this is unimaginable.

Their product might, in any respect events, appear neither white nor black; and, as it should have some colour, and may have neither of those, this colour must be of a mixed character- in reality, a species of colour completely different from either. Again, as Black is a privation of White in the Translucent, so Saline or Bitter is a privation of Sweet in the Nutrient Moist. In sanguineous animals the white of the eye is fat and oily, so as that the moisture of the attention may be proof in opposition to freezing. The opposite compound colours could also be these which aren't based on numbers. This completes our dialogue of the thing of Taste, i.e. Savour; for the other affections of Savours are examined in their correct place in connection with the natural historical past of Plants. Some are both affections or states of sensation, others, means of defending and safe-guarding it, whereas others, again, contain its destruction or negation. Light; while the privation of it is Darkness.

Now, that which when current in air produces gentle may be current also within the Translucent which pervades determinate bodies; or once more, it is probably not current, however there may be a privation of it. Now, each of them may be spoken of from two points of view, i.e. either as precise or as potential. Whence it follows that we might define colour because the restrict of the Translucent in determinately bounded physique. For whether we consider the special class of bodies referred to as translucent, as water and such others, or determinate our bodies, which seem to possess a set color of their own, it's at the exterior bounding floor that each one alike exhibit their color. Hence it is obvious that that in them which is susceptible of color is in each circumstances the identical. We have next to talk of Odour and Savour, both of which are almost the identical bodily affection, although they each have their being in various things. This affection, wrought by the aforesaid Dry in the Moist, capable of transforming the sense of Taste from potentiality to actuality, is Savour.

Savours, as a class, show their nature more clearly to us than Odours, the reason for which is that the olfactory sense of man is inferior in acuteness to that of the lower animals, and is, when in contrast with our other senses, the least excellent of Man's sense of Touch, on the contrary, excels that of all other animals in fineness, and Taste is a modification of Touch. For water is of all liquids the thinnest, thinner even than oil itself, though oil, owing to its viscosity, is more ductile than water, the latter being uncohesive in its particles; whence water is harder than oil to carry within the hand with out spilling. The substance which flows from eyes when decomposing is seen to be water, and this in undeveloped embryos is remarkably chilly and glistening. The rapidity of the movement has the effect of making that which sees and that which is seen appear completely different from each other. This then is one conceivable speculation to explain the genesis of intermediate colours. Because the bodies wherein it subsists should have some excessive bounding surface, so too should this. Flame, for example, and ignited bodies are subject to such extinction, however expertise exhibits that nothing of this kind occurs to the sunlight.
