Letter from Joseph Priestley to Reverend Mr Scholefield

Priestley describes his recent experiments on 'the purification of the atmosphere by vegetation', using water plants. He now believes that all plants emit air 'in a dephlogisticated state'. Priestley seeks advice from Mr Keir on testing for the presence of nitrous acid in vitriolic. The letter also includes family news and greetings.
