"His Highness has been ever since last Thursday, laid up with fever at the Poggio (a country pleasance of the Grand Duke's), an illness brought on by the fatigue of a deer hunt in which his Highness joined on Wednesday the 6th, when the weather was very hot. On the 7th he went with the Cardinal Archbishop of Florence, in a carriage to Miasa, which is five miles from the Poggio; during the journey he suffered much pain in his back. In the afternoon, when he was wont to take some rest, he went into the country and directed the cutting down of some trees to open an avenue, and remained there in the sun and wind. On the 8th, he returned to the Poggio and dined well as usual. After dinner, he was seized with violent vomiting. In the evening, about two hours before sundown he felt unwell, and in order to hide it he sate down to play picquet with the Count of San Secondo; but as his illness increased, he quitted his game, and retired to his chamber where he took some bezoar[236] in broth, then he returned to the company, where, about the time of the Ave Maria, he conversed with the Grand Duchess and others, and so endured his suffering until two hours after sunset, when he was forced to speak of it; whereupon having summoned the physician of his brother, the Cardinal, who was there, he felt his pulse and pronounced him to have fever, and ordered him to go to bed; and that night he did not sleep, and the fever increased. On Saturday morning, the 10th, they took from him fifteen ounces of blood, and in the evening, two hours before sunset, four ounces more; nor did the fever at all diminish, which is considered to be a double tertian without any very painful symptoms, except a little dryness of the skin. It is thought, that the Grand Duke's illness has been caused by his having eaten for several days at his morning and evening meals, mushrooms cooked in various ways, of which he was very fond. The illness of the Grand Duke has much affected the Grand Duchess also, who has fever, but not to any great degree." On the 12th he writes again ... "The Grand Duke ... on the night between Saturday and Sunday was quite easy, and remained so till dinner time. After dinner he did business with his secretaries. Last night he passed quietly enough, although he has had vomitings; but these were occasioned by the medicines given him, and were not violent."
