 to it; as also by the moisture contained in the Amnion, which is no Urine nor Sweat, as some imagine; we having yet lately seen in the House of the said Dr. Stalpart at the Hague in a newborn Child, that his Urachus had no cavity at all, through which the Urine could passe out of the Bladder into the Amnion. The remaining and least part of the liquor of the Milky vessels is transmitted through the Ductus Thoraicus by the Jugular vein into the Blood.

Besides these Vessels there are yet others, that do not exonerate themselves into the Blood, viz. the Ductus Virsungianus, which delivers it self into the Duodenum; and the Ductus Salivales, whereof the Saliva does no less, than the Juyce in the Ductus Virsungianus, serve for Ferment, to wit, the one in the Stomach, and the other in the Intestins. From whence you may easily conclude, not that I hold (as it seems I have been understood) that the least part in the Ferment-vessels concurs to the making of Blood, but that the least part of the Juyce in the Milky vessels is discharged into the Blood.

Concerning the other Quære, Whether also the distribution of this Ferment is made through the Testicles, Kidneys, Breasts, and Salival Glanduls, &c. I answer, that the Salival Glanduls carry their Spittle or Ferment into the Mouth, and that the rest which returns back through the Testicles, Breasts, and other Glanduls, is carried to the Cistern.
