(1) Olla Hansson's Friedrich Nietzsche, quoted by Dr. Hermann Türck in his pamphlet, Fr. Nietzsche und seine philosophischen Irrwege, Jena and Leipzig, 1891. The author has made a careful study of Nietzsche's writings, and his criticisms are judicious and well put. He furnishes no fresh medical details. His knowledge of insanity seems mainly derived from the Handbook of Schüle.—Google Scholar

(12) Dr. Türck has a story that, while staying at Sils Maria, in the Engadine, Nietzsche used to sit and meditate on a tongue of land which ran into the lake. Returning one spring to his beloved mountain solitude, he found that a bench had been erected on the spot for the convenience of visitors. He turned away, never again to put his foot on the spot. My friend Dr. W. R. Huggard, who is a resident physician at Davos-Platz, caused inquiry to be made about Nietzsche at the time of his death. He writes to me, " Very little appears to be known here as to his residence in Sils Maria. He seems to have passed a very quiet life there without making his crankiness conspicuous to the world."—Google Scholar

(13) Professor Theobald Ziegler, of Strasburg, who had pored through Nietzsche's works, line by line in chronological order, finds the first signs of insanity in Zarathustra (written and published in 1883). In all the subsequent works he finds much of what is over-strung, distorted, coarse, and glaring, the loud and shrieking, in increasing intensity.—Google Scholar
