1) _Experiments on animals_ had brought to light the fact that respiration and the action of the heart continued for a time even after the hemispheres of the cerebrum (in dogs) had been separated from their connection with the cerebellum and medulla oblongata, indeed, even if the hemispheres of the cerebrum (in dogs) had been extirpated.[53] He was also led to the same conclusion by 2) _Certain teratological and pathological anatomical experiences_, which he had gathered from his studies of books. He advances cases described by WEPFER, TYSON and RIDLEY, MANGET, KERKRING, MORGAGNI, and others, which showed that although the cerebrum had occasionally been entirely or in part missing in foetuses, yet these deformed foetuses could nevertheless live a shorter or longer time after birth. And in agreement with TULPIUS he calls attention to the great deformation of the cerebrum in the case of hydrocephals. In close connection with this he gives accounts (from VALLISNIERI and others) of extreme cases of petrifications in the brain, regarding which one must suppose that when the cerebrum gradually lost its functions and the vegetative vital functions nevertheless continued for a time, these must then have been regulated by the remaining parts of the central nervous system, that is, by the cerebellum, medulla oblongata and the spinal cord. (See Œc. R. A. I., Nos. 573, 574 _et seqq._). From these experiments and discoveries it was thus evident to SWEDENBORG that the centres for vegetative life are not to be sought for in the cerebrum.
