I will unfold, or wherefore what to some Is foul and bitter, yet the same to others Can seem delectable to eat,--why here So great the distance and the difference is That what is food to one to some becomes Fierce poison, as a certain snake there is Which, touched by spittle of a man, will waste And end itself by gnawing up its coil. Again, fierce poison is the hellebore To us, but puts the fat on goats and quails. That thou mayst know by what devices this Is brought about, in chief thou must recall What we have said before, that seeds are kept Commixed in things in divers modes. Again, As all the breathing creatures which take food Are outwardly unlike, and outer cut And contour of their members bounds them round, Each differing kind by kind, they thus consist Of seeds of varying shape. And furthermore, Since seeds do differ, divers too must be The interstices and paths (which we do call The apertures) in all the members, even In mouth and palate too. Thus some must be More small or yet more large, three-cornered some And others squared, and many others round, And certain of them many-angled too In many modes. For, as the combination And motion of their divers shapes demand, The shapes of apertures must be diverse And paths must vary according to their walls That bound them. Hence when what is sweet to some, Becomes to others bitter, for him to whom 'Tis sweet, the smoothest particles must needs Have entered caressingly the palate's pores. And, contrariwise, with those to whom that sweet Is sour within the mouth, beyond a doubt The rough and barbed particles have got Into the narrows of the apertures.
