Translation / modern text
The letter mentions earlier dates, 11 and 25 July, and includes a passage that may refer to confirming something; the context is illegible, so the subject and meaning of these sentences cannot be established. The date at the top can be read tentatively as 26 June 1691. The address identifies Arthur Forbes in Breslau.
