Here is the correct translation:
After a longer interruption I have finished a bigger genealogical work - the history of the highly respected Zurich patrician family "Hirzel". In agreement with the family I'm willing to send one copy of this not commercially available work to your library. Please tell me, to which address the parcel should be handed over.
Respectfully Dr. C Keller-Escher
