Upon this, all being silent, Florus began thus: What, shall we tamely suffer Plato to be run down? By no means, said I, for if we desert him, Homer must be in the same condition, for he is so far from denying the windpipe to be the passage for our drink, that the dry food, in his opinion, goes the same way. For these are his words:-- From his gullet [Greek omitted] flowed The clotted wine and undigested flesh. ("Odyssey," ix. 373.) Unless perchance you will say that the Cyclops, as he had but one eye, so had but one passage for his food and voice; or would have [Greek omitted] to signify weasand, not windpipe, as both all the ancients and moderns use it. I produce this because it is really his meaning, not because I want other testimonies, for Plato hath store of learned and sufficient men to join with him. For not to mention Eupolis, who in his play called the "Flatterers" says, Protagoras bids us drink a lusty bowl, That when the Dog appears our lungs may still be moist; or elegant Eratosthenes, who says, And having drenched his lungs with purest wine; even Euripides, somewhere expressly saying, The wine passed through the hollows of the lungs, shows that he saw better and clearer than Erasistratus. For he saw that the lungs have cavities and pores, through which the liquids pass. For the breath in expiration hath no need of pores, but that the liquids and those things which pass with them might go through, it is made like a strainer and full of pores. Besides, sir, as to the example of gruel which you proposed, the lungs can discharge themselves of the thicker parts together with the thin, as well as the stomach. For our stomach is not, as some fancy, smooth and slippery, but full of asperities, in which it is probable that the thin and small particles are lodged, and so not taken quite down. But neither this nor the other can we positively affirm; for the curious contrivance of Nature in her operation is too hard to be explained; nor can we be particularly exact upon those instruments (I mean the spirit and the heat) which she makes use of in her works. But besides those we have mentioned to confirm Plato's opinion, let us produce Philistion of Locri, very ancient and very famous physician, and Hippocrates too, with his disciple Dioxippus; for they thought of no other passage but that which Plato mentions. Dio says, that when we feed, the moist parts are about that separated from the dry, and the first are carried down the windpipe, the other down the weasand; and that the windpipe receives no parts of the food, but the stomach, together with the dry parts, receives some portion of the liquids. And this is probable, for the epiglottis lies over the windpipe, as a fence and strainer, that the drink may get in by little and little, lest descending in a large full stream, it stop the breath and endanger the life. And therefore birds have no epiglottis, because
