This excerpt was emailed to me many years ago, as if it had references to the Babis or Bahá'ís. See e.g. note on page 197. But I don't read German and the scan is too poor, and in Gothic font, to OCR. The English version is online at Hathi Trust and Google Books. If you can access either (e.g. from a university library) and find out this information, please contact me. -J.W.
