Corrections. Thanks to my readers for catching these errors.
On Page 134: “By the late nineteenth century, 70-90 percent of the urban population [of Europe] was infected with tuberculosis bacillus. Eighty percent of those who were infected died. Should read: Eighty percent of those who developed active tuberculous died of it.”
On page 196 and all following mentions Mandelkorn should read Mandelkern.
