3. But the flesh, because it is not alive, always requires the same kind of food, for it does not cause any weight in the uterus, nor any inflammation. So that the affection would continue, in some cases, throughout life, unless some fortunate debility should take place, as in the woman who was attacked with dysentery. But does this affection arise from warmth, as it was said, or rather from a fluid state, because there is a fulness as it closes, either because the uterus is neither cold enough to reject it, nor warm enough to bring it to maturity? Wherefore, the disease lasts a long while, like those things which remain a long while before they are matured; but those that are about to come to maturity have an end, and that quickly. Such uteri, being very high up, cause a long delay. And, again, not being alive, it does not cause any pain by its movements, for the movement of the ligament which the living fœtus produces, causes pain. And the hardness of the substance is the effect of imperfect production, for it is so hard that it cannot be cut by the stroke of an axe. All ripe and mature things become soft, but imperfectly digested things are immature and hard. 4. Wherefore, many physicians, deceived by the resemblance, say that women are suffering from myle, if they only see the abdomen elevated without dropsy, and a cessation of the catamenia, when the disease has lasted for a long while. But this is not the case, for the myle is a rare disease. Sometimes there will be collections of cold and moist excrements and fluids, and sometimes of thick ones in this part of the abdomen, if either the nature or the habit is of this kind. For these things afford neither pain nor heat, on account of their cold nature; but if they increase, more or less, they bring no other disease after them, but remain quiet, like some maimed thing. 5. The cessation of the catamenia takes place on account of the excrementitious matter of the body being directed to this point, as when women are nursing; for they occur either not at all, or only in small quantities. A collection of matter from the flesh sometimes takes place between the uterus and the stomach, which has the character of the myle, but is not it. But it is not difficult to know the difference, by touching the uterus; for if it is correctly placed, and not enlarged, it is evident that the disease is not there; but if it is the same as when with child, it will be warm, and cold, and dry, because all the fluids are turned inwards; and the os uteri will be in the same condition as when they are pregnant; but if the enlargement is of any other kind, it will be cold, and not dry when touched, and the os uteri will always be the same.
