Let us once more, then, recall the actual purpose for which Nature has constructed all these parts. Its name, as previously1 stated, is nutrition, and the definition corresponding to the name is: an assimilation of that which nourishes to that which receives nourishment2. And in order that this may come about, we must assume a preliminary process of adhesion, and for that, again, one of presentation. For whenever the juice which is destined3 to nourish any of the parts of the animal is emitted from the vessels4, it is in the first place dispersed5 all through this part, next it is presented, and next it adheres, and becomes completely assimilated.

The so-called white [leprosy] shows the difference between assimilation and adhesion, in the same way that the kind of dropsy which some people call anasarca clearly distinguishes presentation from adhesion. For, of course, the genesis of such a dropsy does not come about as do some of the conditions of atrophy6 and wasting, from an insufficient7 supply of moisture; the flesh is obviously moist enough — in fact it is thoroughly8 saturated9 — and each of the solid parts of the body is in a similar condition. While, however, the nutriment conveyed to the part does undergo presentation, it is still too watery10, and is not properly transformed into a juice, nor has it acquired that viscous11 and agglutinative quality which results from the operation of innate12 heat; therefore, adhesion cannot come about, since, owing to this abundance of thin, crude liquid, the pabulum runs off and easily slips away from the solid parts of the body. In white [leprosy], again, there is adhesion of the nutriment but no real assimilation. From this it is clear that what I have just said is correct, namely, that in that part which is to be nourished there must first occur presentation, next adhesion, and finally assimilation proper.

Strictly13 speaking, then, nutriment is that which is actually nourishing, while the quasi-nutriment which is not yet nourishing (e.g. matter which is undergoing adhesion or presentation) is not, strictly speaking, nutriment, but is so called only by an equivocation14. Also, that which is still contained in the veins15, and still more, that which is in the stomach, from the fact that it is destined to nourish if properly elaborated, has been called “nutriment.” Similarly we call the various kinds of food “nutriment,” not because they are already nourishing the animal, nor because they exist in the same state as the material which actually is nourishing it, but because they are able and destined to nourish it if they be properly elaborated.

This was also what Hippocrates said, viz., “Nutriment is what is engaged in nourishing, as also is quasi-nutriment, and what is destined to be nutriment.” For to that which is already being assimilated he gave the name of nutriment; to the similar material which is being presented or becoming adherent16, the name of quasi-nutriment; and to everything else — that is, contained in the stomach and veins — the name of destined nutriment.
