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.
