Note 156 — Chapter VI · DISHARMONIES IN THE INSTINCT OF SELF-PRESERVATION
P. Chalmers (Peter Chalmers) Mitchell translation
These words are quoted by Ebstein in his “Die Kunst das menschliche Leben zu verlängern,” p. 51, 1891. I have been unable to find Paul Bert’s own words, as the reference given by Ebstein is bibliographically incorrect.
