Summary:

Delighted that CD does not hesitate to follow his theory to its last consequences. "This is far more difficult in England than in Germany."

Wilhelm Müller in his new book [Beiträge zur pathologischen Anatomie und Physiologie des menschlichen Rückenmarks (1871)], adduces many facts in favour of CD’s theory.

Various observations on the human ear. [See Descent, 2d ed., p. 14 n.]
