Description
Denis Papin's improvement on his digester. The image shows a brass cylinder lined with pewter. The cylinder is filled with water with an inch left from the top, and covered with a lid which is also lined with pewter. The digester is then fastened into an iron frame, to apply pressure on the cover. The cylinder can then be turned horizontally and heated. Denis Papin presented the design to the Royal Society on 5 May 1686. The figures were printed in Denis Papin, A continuation of the new digester of bones (1687).
Transcription
Although the digester such as it was publisht five years ago may be of a great advantage for saving fire and time, and for extracting gellys even out of bones that would never yield any by the ordinary ways.
