In the first Parliament of 1640, while it seemed to favour the measures of the court, he wrote a little tract in English wherein he demonstrated as himself tells us, that all the power and rights necessary for the peace of the kingdom, were inseparably annexed to the sovereignty of the King's person. But in the second parliament of that year, when they proceeded fiercely against those who had written or preached in defence of the regal power; he was the first that fled, went over into France, and there continued eleven years. Whether from the dread of assassination, or as some have thought from the notion of ghosts and spirits, is uncertain, but he could not endure to be left in an empty house; whenever the earl of Devonshire removed, he would accompany him; even in his last stage from Chatsworth to Hardwick, when in a weak condition, he dared not be left behind, but made his way upon a feather bed in a coach, tho' he survived the journey but a few days. He could not bear any discourse of death, and seemed to cast off all thoughts of it; he delighted to reckon upon longer life. The winter before he died he had a warm coat made him, which he said must last him three years, and then he would have such another. A few days after his removal to Hardwick, Wood says that he was struck with a dead palsy, which stupified his right side from head to foot, depriving him of his speech and reason at the same time; but this circumstance is not so probable, since Dr. Kennet has told us, that in his last sickness he frequently enquired, whether his disease was curable; and when it was told him that he might have ease but no remedy, he used these expressions. 'I shall be glad then to find a hole to creep out of the world at;' which are reported to be his last sensible words, and his lying some days following in a state of stupefaction, seemed to be owing to his mind, more than to his body. The only thought of death which he appeared to entertain in time of health, was to take care of some inscription on his grave; he would suffer some friends to dictate an epitaph, amongst which he was best pleased with these words: "This is the true Philosopher's Stone." He died at Hardwick, as above-mentioned, on the 4th of Dec. 1679. Notwithstanding his great age, for he exceeded 90 at his death, he retained his judgment in great vigour till his last sickness.
