Autograph Letter in the third person (”The Queen has recd. Mr. Royle’s letter…”), to Arnold Royle (Surgeon in Ordinary to HRH Prince Leopold), about the health of Prince Leopold, returning “the Extract” so that he can make notes about it, saying that she has spoken to Prince Leopold who promises to be guided by Royle, asking Royle to repeat this to Captain Waller. 2 full pages 7 x 4½ inches, monogrammed mourning stationery, integral blank leaf, in superb condition. Osborne, 26 August 1879. “It blows so hard that it wd. be as well to stop at Yarmouth.” Queen Victoria (reigned 1837-1901). Her youngest son, Prince Leopold, Duke of Albany (1853-1884) suffered from haemophilia and epilepsy from childhood, and his ill-health was a constant grave concern to his mother. The Queen attempted to limit Prince Leopold’s freedom to act independently. Arnold Royle, who was the Prince’s personal physician from 1876 until the Prince’s death in 1884, found himself caught between his strong-willed patient, determined to lead an active life, and his equally strong-willed mother.
