Bath Straight-Line handstamps - 1774 & 1792

Here are a couple of Bath handstamps from the 18th century.  This first cover is from Bath to London, redirected to Edinburgh in June 1774.  The main interest to me is from the contents (transcribed to the right of the cover) which may describe attacks of Ménière's disease, which  was first identified in the early 1800s by Prosper Ménière.

This second cover is also from Bath to London.  Bath had a lot of visitors 'taking the waters'.
