914. When I inquired what these things signified or represented I was told that such is the representation of the infundibulum of the brain, the nature of which is evident from its description: namely, that it receives spirits resolved from the blood, and besprinkled on the way with a suitable serum lest they exhale through the pores. They are then carried off through very many paths into the large ventricles, and thence through their own foramen under the pineal gland to the third cleft or ventricle, and from there to the infundibulum and so to the pituitary gland. There they are separated, and by determinate paths they are carried down to the extremities of the sinuses and so to the jugular veins. Thus the spirits resolved from the blood globules come to the cortical beginnings, and being there conjoined with new spirituous essences, are carried down through their fibers into the ventricles, and then through the infundibulum into the blood, that they may vivify the dry and lifeless blood in the extremities of the sinuses. After this they are borne along to the chyle, fresh from the body, and being conjoined therewith in the heart, thus vivify the mass of the blood in the heart. All this, together with the whole process so tedious to describe, was said by angels to other angels in a moment, almost in a second.
