Product Description

Isaac Milner (1750-1820) -mathematician, divine, Dean of Carlisle- is writing to a “Dear friend” describing his experiments to investigate whether water was the cause of oxidisation of lead. His experiments show that air was the culprit and he expands his experiments to produce tincture of sulphur which is used to identify the existence of lead in various substances including wine. He notes that Thomas Watson, Bishop of Llandaff names this substance as “Liquor Viri Probationes” in one of his lectures. The letter is signed “your dear friend affect J.M.”.
