Marat "practiced in Paris well-known for his activities in the French Revolution; Benjamin Franklin was interested in his electrical experiments but his works especially on fire and heat were discredited." – Cole. / There is apparently one known copy with a portrait plate perhaps spurious or added to the work and yet most every copy does not mention a portrait. Cole notes two copies without a portrait and one at Oklahoma University he saw only in microprint where a portrait was present – Cole says "appears to have a portrait." Of several copies found for sale none had a correct portrait. I inquired about the Oklahoma copy and they verified that it does not in fact have a portrait see above. Net result: the book was not issued to the public with a portrait. Copies mentioning a portrait will thus be referencing a tipped-in plate from another source presumably an unknown source. / "In this book Marat attempts to give a mechanical explanation of the phenomena of heat by the use of his theoretical 'fluide igne.' Some 166 experiments are described in support of his views." – Cole. / NOTE: "Jean-Paul Marat was a leader of the French Revolution along with others like Danton and Robespierre. In 1793 he was assassinated while soaking in a bath—one of the most famous murders in French history. While there is no question about who killed him the reason he was in the bath has confounded historians for centuries. And this mystery may have just been solved." "Marat bled profusely when he was stabbed and his blood soaked the papers he was working on. These were kept by his sister and eventually found their way to the National Library of France. / French forensic scientist Philippe Charlier working with a team of specialists was recently able to extract DNA from these centuries-old papers. As well as finding DNA that confirmed Marat's ancestry French and Italian the team found a number of non-human DNA fragments. / These fragments ruled out many of the popular theories—no syphilis no scabies no leprosy or tuberculosis. But there was strong evidence of an advanced fungal infection of Malassezia restricta. This would explain his pain and sores and would probably have damaged his immune system as well leaving him open to other infections. / While the answer can't be known for sure modern technology seems to have validated the belief of Marat—ever the scientist—that the sewers of Paris were his undoing." – Keith van Sickle The Good Life.
