He was careful to point out that, unless the cow's udder wa3 infected the milk was free from the tuberculous bacilli, but always there was the chance that a cow, affected in other parts of the body by tuberculosis, was a potential infector ! of tho milk. He laid the blame on civilisation, on the " speeding up" and forcing of the milk yield by modern cattle feeding. In the old days a cow that yielded 2000 gallons of milk a year was unheard of.
