Ewen congratulates BR on obtaining a scholarship at Trinity College, Cambridge. Ewen was BR's tutor; BR mentions him in "Greek Exercises". BR used to discuss theology with him. Ewen was an atheist and BR suspects that he left because others thought he was undermining BR's faith. Ewen also introduced BR to Karl Marx and non-Euclidean geometry. Ewen writes: "I congratulate you with all my heart though such a feat is almost too much for mere congratulation. In fact such an exhibition of mental athletics rather excites a feeling of admiring wonder. I would hardly venture to tell you so if I did not know that you are too sensible to allow your head to be turned by success."
