This circumstance, added to his well known integrity and dauntless courage, made me very desirous to engage him. A youth passed in solitude, my best years spent under your gentle and feminine fosterage, has so refined the groundwork of my character, that I cannot overcome an intense distaste to the usual brutality exercised on board ship: I have never believed it to be necessary; and when I heard of a mariner equally noted for his kindliness of heart, and the respect and obedience paid to him by his crew, I felt myself peculiarly fortunate in being able to secure his services. I heard of him first in rather a romantic manner, from a lady who owes to him the happiness of her life. This, briefly, is his story.
In this addition to the 1831 edition, Walton turns the focus of this passage about the ship’s master onto himself and how his older sister fostered him somewhat like a mother and helped build his character. Where 1818 says little about Mrs. Saville’s character, Walton now likens her to Elizabeth, who will also act as a mother figure to Victor Frankenstein after his own mother’s death. The 1831 edition more strongly accentuates the domestic world throughout the new version.
