24 June 1761 Spt. at Dulwich Wells with Mr Hall 6d

The Green Man Inn was where people came to take the waters at Dulwich Wells Spa.
This was where Dulwich Common Road meets Lordship Lane today. A pub has stood on the site ever since. Currently it is part of the Harvester chain which would be a really alien idea to Thomas!
