Book III Chapter 4

Thus the two faculties¹ are clearly to be seen in the case of the uterus; in the case of the stomach they appear as follows:— Firstly in the condition of gurgling, which physicians are persuaded, and with reason, to be a symptom of weakness of the stomach; for sometimes when the very smallest quantity of food has been ingested this does not occur, owing to the fact that the stomach is contracting accurately² upon the food and constricting³ it at every point; sometimes when the stomach is full the gurglings yet make themselves heard as though it were empty. For if it be in a natural condition, employing its contractile faculty⁴ in the ordinary way, then, even if its contents be very small, it grasps the whole of them and does not leave any empty space. When it is weak, however, being unable to lay hold of its contents accurately, it produces a certain amount of vacant space, and amount of vacant space, and allows the liquid contents to flow about in different directions in accordance with its changes of shape, and so to produce gurglings.

Thus those who are troubled with this symptom expect, with good reason, that they will also be unable to digest adequately; proper digestion⁵ cannot take place in a weak stomach. In such people also, the mass of food may be plainly seen to remain an abnormally long time in the stomach, as would be natural if their digestion were slow. Indeed, the chief way in which these people will surprise one is in the length of time that not food alone but even fluids will remain in their stomachs. Now, the actual cause of this is not, as one would imagine, that the lower outlet⁶ of the stomach, being fairly narrow, will allow nothing to pass before being reduced to a fine state of division. There are a great many people who frequently swallow large quantities of big fruit-stones; one person who was holding a gold ring in his mouth, inadvertently swallowed it; another swallowed a coin, and various people have swallowed various hard and indigestible objects; yet all these people easily passed by the bowel⁷ what they had swallowed, without there being any subsequent symptoms. Now surely if narrowness of the gastric⁸ outlet were the cause of untriturated food remaining for an abnormally long time, none of these articles I have mentioned would ever have escaped. Furthermore, the fact that it is liquids which remain longest in these people’s stomachs is sufficient to put the idea of narrowness of the outlet out of court. For, supposing a rapid descent were dependent upon emulsification⁹, then soups, milk, and barley-emulsion would at once pass along in every case. But as a matter of fact this is not so. For in people who are extremely asthenic it is just these fluids which remain undigested, which accumulate and produce gurglings, and which oppress and overload¹⁰ the stomach, whereas in strong persons not merely do none of these things happen, but even a large quantity of bread or meat passes rapidly down.

And it is not only because the stomach is distended¹¹ and loaded and because the fluid runs from one part of it to another accompanied by gurglings — it is not only for these reasons that one would judge that there was an unduly¹² long continuance of the food in it, in those people who are so disposed, but also from the vomiting¹⁴. Thus, there are some who vomit¹³ up every particle of what they have eaten, not after three or four hours, but actually in the middle of the night, a lengthy¹⁵ period having elapsed since their meal.

Suppose you fill any animal whatsoever¹⁶ with liquid food — an experiment I have often carried out in pigs, to whom I give a sort of mess of wheaten flour and water, there after cutting them open after three or four hours; if you will do this yourself, you will find the food still in the stomach. For it is not chylification which determines the length of its stay here — since this can also be effected outside the stomach; the determining factor is digestion which is a different thing from chylification, as are blood-production and nutrition. For, just as it has been shown that these two processes depend upon a change of qualities, similarly also the digestion of food in the stomach involves a transmutation of it into the quality proper to that which is receiving nourishment¹⁷. Then, when it is completely digested, the lower outlet opens and the food is quickly ejected through it, even if there should be amongst it abundance of stones, bones, grape-pips, or other things which cannot be reduced to chyle. And you may observe this yourself in an animal, if you will try to hit upon the time at which the descent of food from the stomach takes place. But even if you should fail to discover the time, and nothing was yet passing down, and the food was still undergoing digestion in the stomach, still even then you would find dissection¹⁸ not without its uses. You will observe, as we have just said, that the pylorus is accurately closed, and that the whole stomach is in a state of contraction¹⁹ upon the food very much as the womb contracts upon the foetus. For it is never possible to find a vacant space in the uterus, the stomach, or in either of the two bladders — that is, either in that called bile-receiving or in the other; whether their contents be abundant or scanty²⁰, their cavities are seen to be replete²¹ and full, owing to the fact that their coats contract constantly upon the contents — so long, as least, as the animal is in a natural condition.

Now Erasistratus for some reason declares that it is the contractions²² of the stomach which are the cause of everything — that is to say, of the softening²³ of the food, the removal of waste matter, and the absorption of the food when chylified [emulsified].

Now I have personally, on countless²⁴ occasions, divided the peritoneum of a still living animal and have always found all the intestines²⁵ contracting peristaltically upon their contents. The condition of the stomach, however, is found less simple; as regards the substances freshly swallowed, it had grasped these accurately both above and below, in fact at every point, and was as devoid²⁶ of movement as though it had grown round and become united with the food. At the same time I found the pylorus persistently²⁷ closed and accurately shut, like the os uteri on the foetus.

In the cases, however, where digestion had been completed the pylorus had opened, and the stomach was undergoing peristaltic movements, similar to those of the intestines.
