Note 239 — 200.
Reading edition
Louis XV. died May 10, 1774, of small-pox. "Two of the King's daughters," writes Walpole (May 15, 1774), "though they never had the small-pox, attended him." Both the princesses caught the disease, but recovered. Louis XVI. and his two brothers were vaccinated, and the successful results did much to establish the practice on the Continent.
