This note is possibly connected with the medical certificate Bruckner sought from the eminent Viennese doctors Friedrich Kraus and Guido von Török in July 1892, which he then submitted to the Hofkapelle, requesting permission to retire.  Friedrich Kraus (1858-1936), an eminent cardiologist, may be the recipient of Bruckner's message.  Bruckner's printed visiting card refers to his Honorary Doctorate of Philosophy, which he was awarded on 7 November 1891.  The Riedhof was a restaurant frequented by Bruckner and many doctors, including Billroth (the dedicatee of Brahms's Op.51 string quartets), who was a friend of von Török's.  Bruckner's Te Deum was one of his most successful works, receiving around thirty performance during his lifetime.
