II. Duka Tivadar munkálkodása - 4. S. C. Maian levelei Duka Tivadarhoz
4. The Vicarage, Broadwindsor, Dorset. April 12, 1884. My dear Sir I should be sorry you took the trouble of coming all this way for only half an hour's visit! You don't know the distance at which we are from the great metropolis. Unfortunately at present our only spare room is occupied; and I could not allow you to lodge any where but under my roof. 1 shall however, be in London this season, I hope; and I will do myself the pleasure of calling. - I am arranging and ticketting Csoma's Tibetan books. When ready they shall be sent to you at once. I'm looking them over. They so remind me of him! There was something so kind, simple and winning about his manner. But my impression was, at the time, that he was not duly appreciated. Many thanks for the enclosed. Believe me yours very faithfully S. C. Malan
