varicous circlings, which are ••oyned with the spermatical Artery by Anastomoses or In∣oculations, and at length it ends in the Testicle of its own side. But the right spermati∣call vein [χ] arises not out of the Emulgent, but the Trunk it self, and the forepart of it, a little beneath the Emulgent-vein, and afterwards observes a like course with the former. And thus they are in males, though we may observe nature oftentimes vary∣ing in them: but in Women, although they arise in the same manner, and observe the same course with those in Men, as far as the Holy-bone; yet they fall not out of the Peritoneum, nor reach into the share-bones, but before they come to the Testicles, are cleft into two unequall branches; the lesser of which is scattered into the sides of the womb, toward the bottom of it; the greater being joyned to the spermatical Artery, and inocu∣lated with it, enters into the Testicle of its own side. Last of all the fourth pair is cal∣led [X] Lumbares, the Loin-veins [444] two, or three which the Hollow-vein sends forth from its back side, which looks towards the bodies of the Rack-bones of the Loins; and therefore they are not to be seen, unless the Trunk of the Hollow-vein be lif∣ted up. These veins go in through the holes of the Rack-bones, through which the Nerves go out, and so carry nourishment to the Spinal marrow. From them two other veins, tyed on both sides to the side of the Marrow, ascend toward the brain, with which afterward two veins descending from the internall Jugular, are joyned by an Anastomosis or Inoculation.
These propagations being thus sent out, when the Hollow-vein has almost attained to the Sacrum, or Holy-bone, about the fifth Rack-bone of the Loins, it inclines under the great Artery, and is cut into two notable branches called Iliaci [XX] which having gone a little way are again cleft into two others [Y and Z] of unequal bigness, of which one is called the inner, the other the outer. The inner is less, the outer lager and greater. But before they be so divided, they scatter two other propagations, the first of which [5] is commonly called Muscula superior, the upper Muscle-vein, which is disseminated overthwart, through the Muscles of the Loins, and Abdomen, or paunch, from whence I would call it Muscula lumbalis, the Muscle-vein of the Loins: the other [6] is named Sacra, or the Holy-vein, because it reaches some little twigs to the upper holes of the Holy-bone, for the nourshing of the said bone and the Spinal-marrow.
But from both the Iliacal branches many veins issue, before they go out of the Peri∣toneum or Rim of the Belly toward the Legs; and from the inner branch two. The first [7] arises from the out-side called Muscula media, the middle Muscle-vein; because it is scattered into all the Muscles of the Buttocks, and into their skin: For it carries aliment to all those Muscles, which are of the out-side, or Back of the bone Ilium or Hanch-bone, as also to the very joint of the Hip, that for this cause it ought to be especially taken notice of by them who would somewat curiously consider the cause of the ach in the Hip, or the Sciatica. I should think that this vein may not be amiss called Glutaea from its insertion, because it is implanted into the Muscles called Glutaei, or Muscles of the Buttocks. The other [8] grows out of the inside, and is a notable vein, called Hypo∣gastrica, or the vein of the water-course, from its distribution into almost all the parts of the Hypogastrium, or water-course. From this issues a branch named Haemorrhoidalis exter∣na, the outer Emroid-vein, because if at any time it swels with a more faeculent blood, or hot, or salt, it makes the outward Emroids of the Fundament. This affords twigs to the holes of the Os sacrum, or Holy-bone, but bestows greater branches upon the Muscles of the Rectum Intestinum, or the Strait gut, as far as to the outer skin of the Fundament. There is also another branch arising from the same Hypogastrick-vein, which we call Cysticus, the Bladder-branch, and is worthy of observation both in men and women; in men, be∣cause it is spent upon the Bladder; but in women, because in them being sustained with a fat membrane, it goes with some twigs to the Bladder; but with more to the bottom of the Womb; and with more manifest ones to the Neck of it, by which veins alone some think that the monthly courses flow in Virgins, and some also think the same in Wo∣men. But the monthly courses do not only flow out by these branches, but by those also which we told you were sent from the spermatical branch, and which go to the bottom of the womb, not to the Neck. For the menstruous blood is is usually purged out, whether in Virgins or women, every month; not only through the Neck, but especialy through those passages of the Womb, called Cotyledones. Which we have shown here at Padua, publickly in the Theater, the first year of our being Professor, in the carkass of a certain Woman having her monthly courses. For we saw that the Hypogastrick branches, and the sperma∣tick vessels with the Testicles were filled with blood, and that the Womb it self did pour out a thicker blood, the little mouths of the veins in the inner part of the Womb lying o∣pen, and manifestly gaping. Yet I saw twice in others, that the menstruous blood came out of the veins of the Neck only, not also out of the womb, and in another on the contrary that it flowed out of the Womb only. But the ordinary way is for women to be purged at them both and not at one only, except when besides the intent of nature obstructions do seem to hinder their flowing.
