8. Van Gogh suggests that
Van Rappard had a venereal disease (in November 1882 Van Rappard fell seriously ill). Later he turned out to have a ‘nervous fever in the head’ (
letter 310), which usually meant encephalitis, but could also be a name for other fevers affecting the brain. Van Rappard spent July and August 1883 at the health resort Soden in northern Germany to recuperate. See exhib. cat. Amsterdam 1974, pp. 79, 83.
