All the time we lived at Chelsea we had constant intercourse with Lady Noel Byron and Ada, who lived at Esher, and when I came abroad I kept up a correspondence with both as long as they lived. Ada was much attached to me, and often came to stay with me. It was by my advice that she studied mathematics. She always wrote to me for an explanation when she met with any difficulty. Among my papers I lately found many of her notes, asking mathematical questions. Ada Byron married Lord King, afterwards created Earl of Lovelace, a college companion and friend of my son. Somerville had formed a friendship with Sir Henry Bunbury when he had a command in Sicily, and we went occasionally to visit him at Barton in Suffolk. I liked Lady Bunbury very much; she was a niece of the celebrated Charles Fox, and had a turn for natural history. I had made a collection of native shells at Burntisland, but I only knew their vulgar names; now I learnt their scientific arrangement from Lady Bunbury. Her son, Sir Charles Bunbury, is an authority for fossil botany. The first Pinetum I ever saw was at Barton, and in 1837 I planted a cedar in remembrance of one of our visits. Through Lady Bunbury we became intimate with all the members of the illustrious family of the Napiers, as she was sister of Colonel, afterwards General Sir William Napier, author of the "History of the Peninsular War." One day Colonel Napier, who was then living in Sloane Street, introduced Somerville and me to his mother, Lady Sarah Napier. Her manners were distinguished, and though totally blind, she still had the remains of great beauty; her hand and arm, which were exposed by the ancient costume she wore, were most beautiful still. The most sincere friendship existed between Richard Napier and his wife and me through life; I shall never forget their kindness to me at a time when I was in great sorrow. All the brothers are now gone. Richard and his wife were long in bad health, and he was nearly blind; but his wife never knew it, through the devoted attachment of Emily Shirriff, daughter of Admiral Shirriff, who was the comfort and consolation of both to their dying day. Maria Edgeworth came frequently to see us when she was in England. She was one of my most intimate friends, warm-hearted and kind, a charming companion, with all the liveliness and originality of an Irishwoman. For seventeen years I was in constant correspondence with her. The cleverness and animation as well as affection of her letters I cannot express; certainly women are superior to men in letter-writing.
