Kekulé tells how he discovered the constitution of benzene in the _Berichte der Deutschen chemischen Gesellschaft_, V. XXIII, I, p. 1306. I have quoted it with some other instances of dream discoveries in _The Independent_ of Jan. 26, 1918. Even this innocent scientific vision has not escaped the foul touch of the Freudians. Dr. Alfred Robitsek in "Symbolisches Denken in der chemischen Forschung," _Imago_, V. I, p. 83, has deduced from it that Kekulé was morally guilty of the crime of OEdipus as well as minor misdemeanors.
