But Arnauld would become a living Exhibit. Symptoms would set in that were so obvious and dramatic as to furnish a topic of study for the Royal Society. Why, a whole jury of English savants could stand around poor Arnauld with their magnifying lenses and their notebooks, observing the changes in his physiognomy, noting them down in Latin and rendering them in labored woodcuts. Most of these symptoms had to do with the Humour of Passion. For a few moments, Arnauld would stand fast as the insult sank in. His face would turn red as the vessels in his skin went flaccid, and consequently ballooned with blood from a heart that had begun to pound like a Turkish kettle-drum signalling the onset of battle. But this was not when the attack came, because Arnauld, during this stage, was physically unable to move. All of his activity was mental. Once he got over the first shock, Arnauld’s first thought would be to convince himself that he had reined in his emotions now, got himself under control, was ready to consider matters judiciously. The next few minutes, then, would be devoted to a rehearsal of the recent encounter with Blaise. Affecting a rational, methodical approach, Arnauld would marshal whatever evidence he might need to convict Blaise of being a scoundrel, and sentence him to death. After that, the attack would not be long in following. But to one who had not been there with those Fellows of the Royal Society to observe all that had led up to it, it would seem like the spontaneous explosion of an Infernal Device.
