...life). The other half develop true pulmonary tuberculosis (the type that kills) when they become adolescents. About the same number of boys and girls, who never had the childhood form, catch it from others when they grow up. Three good means of diagnosis for early tuberculosis exist: X-rays; tuberculin tests; precipitation of a suspect's blood serum by fatty phosphatide fractions of the tuberculosis germ.* Mild doses of infection immunize a person. Massive doses present great future dangers. Attempts to vaccinate babies with living cultures of the germs are likely to prove harmful, because it has been impossible...
...Sciences or from his directorship at the Kaiser Wilhelm Institute for Physics. Yet the Einsteins, if they were really in need, might look with confidence to their very rich relatives, the Kochs and Dreyfuses of Germany and France.

A number of American cities have shown that it is possible to insist on milk from tuberculin-tested herds, with the result that herds in their vicinity are relatively free from the disease, as compared with the mass infection of cattle in the Illinois Dis- trict...
