Chalybeate Well inscription

Close-up of inscription on the Chalybeate Well, Well Walk, Hampstead.
Commemorating the bequest by the Earl of Gainsborough, then an infant, through his mother The Hon Susanna Noel of six acres of land for the perpetual benefit of the poor of the Parish of Hampstead.
Note that travellers are exhorted first to think of the benefactor and then, almost as an afterthought, praise the lord!
