Petersen diseovered tliat liy injectinj; hormone called oxytocin into the blood f the artificial cow. the milk is released reely from the U(hler. Oxytocin is manufactured in a cow ' s kxM. in the i)ituitary gland. When a cow is contented, the hormone flows normally into the l)loo(l stream and the milk is released freely. This has |)artially solved the |)rol)leTn of wh - a cow some- times fails to let down her milk. The experimental cow fails to give milk only when there is no udder avail- able. The machine cannot operate un- less a cow has heen freshlv slaughtered. Once a fresh udder is attached the ma- chine can be run indefinitely, provided. of course, that blood runs through it. Other studies conducted by Prof. Petersen have shown that cows have a definite social order, ranging from the queen, who holds her position by out- butting the others, down to the cow who has no aspirations to the throne.
