From Hermann Brehmer 17 April 1876
Summary
Discusses geographic distribution of tuberculosis and possible explanations for disease-free areas and populations.
Does not think a local population with some distinct physiological character can properly be designated as a race. Thinks local conditions, not natural selection, responsible for such characters. Ernst Haeckel agrees. Asks CD’s opinion.
