Poor old Papin had indigestion so he worked out a way to solve the problem! Apply some heat, create some pressure, and “Hey presto” problem solved?? Well, it’s as good a way to start the week as any. What was Mr. Papin’s digester for, and did it solve his problem?
there is a protein in the juice of papaya, named and sold as 'Papain', it has a "digester" role

From The Daily Telegraph 30 September 1893, about a dinner attended by members of the Royal SocietyThat raises the knotty question of what ladies were expected to sniff when they suffered an attack of the "vapours", now that hartshorn was being put to an (unspecified) nobler use? NB the article actually (mis)spells it Papan's. I wouldn't have found it if I could type properly.
A figurative Papine's sic digester. From a lively and frank exchange of views carried out in the letter columns of the Brighton Patriot, this on Tuesday 23 May 1837. Written by someone signing himself "Vindex", it concerns remarks a Mr Horne had made ("marrowless bones") about his criticism of Mr Horne's works.
Looks like an illustration from L'Eau, by G. Tissandier, Hachette, Paris, 1873 PS, Not, as I first thought, an illustration archive.org/details/bub_gb_EWo8EsfZshgC/page/n209/mode/2up from L'Eau, but probably a copy in a later English language scientific publication. He was an early pioneer in steam power, and incorporated a pressure relief valve in his 'Marmite de Papin' an invention which saved many, but not all, steam boilers from exploding. His later papers were released by the Royal Society without payment or permission. Newcomen probably based some of his early steam designs on Papin's work. He died a pauper, fulfilling the heading 'Poor old Papin' His statue in Blois in France goo.gl/maps/K9xLCs7DndQQHaht9
Pressure cooker? I thought it was a metal working furnace thing.
The 'nobler use' for hartshorn jelly produced by Pipin's invention referred to in the Daily Telegraph article above is explained by a line in the wikipedia entry for hartshorn:instead of its use for the vapours and so back to human the digestion system, but the other end from https://www.flickr.com/photos/beachcomberaustralia 's burp.

Can anyone read the engraver/illustrator's signature (see note)? À la .... ??
https://www.flickr.com/photos/[email protected] It is a pressure cooker, and it looks from the length of the release valve lever as though it operates at a significantly higher pressure than a modern one, unless there isn't a great fit on it. I wonder how often they blew up.
https://www.flickr.com/photos/beachcomberaustralia It seems there are dictionaries of engravers' marks, but they don't seem to be available online (or not without putting in more effort than I can be bothered with).
Here's an interesting treatise on how hard done by engravers were for recognition: www.nms.ac.uk/collections-research/our-research/highlight...
