Being unwittingly on his deathbed, the philosopher dictated his last letter to his absent host and friend Lord Arundel:My very good Lord,—I was likely to have had the fortune of Caius Plinius the elder, who lost his life by trying an experiment about the burning of Mount Vesuvius; for I was also desirous to try an experiment or two touching the conservation and in-duration of bodies. As for the experiment itself, it succeeded excellently well; but in the journey between London and High-gate, I was taken with such a fit of casting as I know not whether it were the Stone, or some surfeit or cold, or indeed a touch of them all three. But when I came to your Lordship's House, I was not able to go back, and therefore was forced to take up my lodging here, where your housekeeper is very careful and diligent about me, which I assure myself your Lordship will not only pardon towards him, but think the better of him for it. For indeed your Lordship's House was happy to me, and I kiss your noble hands for the welcome which I am sure you give me to it. I know how unfit it is for me to write with any other hand than mine own, but by my troth my fingers are so disjointed with sickness that I cannot steadily hold a pen.
