before; only we will add this, that some of the Glandules have Nerves, as those of the Brests, which they receive from the parts lying under them, that is, from the intercostal, by which it comes to pass, that they have most exquisite sense. Others want a nerve, as those which serve only for division of the vessels, and which have no action, but only use.
They be two in number, on each side one, seated at the sides of the Sternon upon the fourth, fifth, and sixth true ribs.
Wherefore they have connexion with the mentioned parts with their body, but by their vessels with all other parts, but especially with the womb by the reliques of the mamillary veins and ar∣teries, which descend down at the sides of the Brest-blade; in which place these veins insinuating themselves through the substance of the Muscles, are a little above the Navel conjoyned with the Epigastricks, whose original is in some sort opposite to the Hypogastricks, which send forth bran∣ches to the womb. By the meeting of these it is more likely that this commerce should arise, than from other, and those almost capillary branches, which are sometimes seen to descend to the Womb from the Epigastrick.
They are of a cold and moist temper; wherefore they say, that the blood by being converted into milk, becomes raw, flegmatick and white by the force of the proper flesh of the Dugs. Their action is to prepare nourishment for the new-born Babe, to warm the heart from whence they have received heat, and to adorn the Brest.
By this you may know, that some Glandules have action, others use, and some both. At the top of the Dugs there are certain hillocks, or eminencies called Teats or Nipples, by sucking of which the Child is nourished through certain small and crooked passages, which though they ap∣pear manifest to the sight, whilst you press out the milk by pressing the Dug, yet when the Milk is pressed out, they do not appear, nor so much as admit the point of a Needle, by reason of the crooked ways made by nature in those passages, for this use, that the Milk being perfectly made, should not flow out of its own accord against the Nurse's will. For so the seed is retained and kept for a certain time in the Prostats.
