4. And when the appearances cease to take place directly, the uterus shows that, if there is any difficulty, it will become empty and dry, and wanting in moisture, and there will be no remains in the passage. When the uterus, therefore, is capable of contraction, it shows that it is in a proper state for receiving whatever is brought to it, when it is in this state without pain, and indeed is insensate; and it is good that the os uteri should not be in any other condition. This shows that there is no reason why it should not close at the proper time. This is the manner of considering the os uteri, whether it is in a healthy condition or not. CHAPTER III. These ought to be the symptoms of the uterus itself after purification. First of all, that the woman should dream of sexual intercourse, and project her seminal fluid readily, as if a man were lying with her; and if this symptom occur frequently, it is better. And when she has arisen, sometimes she should require the same treatment as if she had been with a man, sometimes she should be dry; but this dryness should not be immediate; but after awaking she should be fluid, sooner or later, about as much as half a short day. The humidity should be of the same kind as if she had been with a man. For all this shows that the uterus is in a fit state to receive what is given it, and that the cotyledons are drawn up and will retain what they have received, and be unwilling to part with it. 2. A flatulent state of the uterus is also a good sign, when it enlarges and discharges the wind as the bowels do without pain, and when it becomes larger and smaller without any symptom of disease; for these symptoms show that the uterus is not in want of what is necessary nor sluggish, either naturally or from disease, but that it will be able to find room by growth for anything that it may receive, for it has the power of dilation. When this is not the case, the uterus is too thick, or some natural defect or disease has rendered it insensible. For this cause it cannot nourish, but it will destroy the embryo, if the symptoms are violent, while the embryo is small; if they are less so, when it is larger; if the uterus is slightly affected, the offspring will be inferior, as if it had been fed in an inferior vessel.
