This letter was sent from Domburg to Metz in 1895
Some parts I can read:
.. Kaiserlichen Bezirks-Praesidenten ....Freiherrn ...
And what would that Kaiserlichen Bezirks-Praesident for a person (profession) be?
I'm not sure about the last word in the third line, but i think it reads:
An seine Hochwohlgeboren
den kaiserlichen Bezirks-Praesidenten Herrn Freiherrn
von Hammerstein, Ritterhof 2
So, the letter was sent to Hans von Hammerstein-Loxten, at that time Bezirkspräsident/Président du département (= District President) of Lothringen/Lorraine. As already said, i'm not sure about the address "Ritterhof 2". The Bezirkspräsidium itself was situated at the Regierungsplatz at Metz, cf. the city map of Metz from "Meyers Großes Konversations-Lexikon" 1905:
Meyers doesn't list a street or place named "Ritterhof", so it's quite likely that my reading isn't correct...
