Object history
11 February 1685, ‘Dr. Papin shewed a way, by which filtrations through cap-paper might be made suddenly and with great quantities of liquor by the help of the pneumatic engine. There being a pipe from the strainer to the exhausted receiver, the liquor was driven forcibly by the weight of the air. It was tried with a solution of sugar in water, which became very clear’ (Birch 4:366).
