 * 2) **What experiment did they perform (briefly outline)?** Realized that may cows were dying from anthrex. Preformed a very careful study of anthrax and realized some cows got it worse then others. Injected two cows with a strong dose of the anthrex bacteria. The cows didn't get the disease. Found out that the cows aready had anthrax. Believed that giving them a mild attack might prevent the cows from getting the disease later. After many experiements later he finally produced a weakened and harmless form of the bacteria. Later he found out that cows and even sheep could get this harmless form of athrax and they will recover. They were then when put with other animal with the sever case of the bacteria they were immuned from it.
 * 3) **Did they experiment because of an accidental discovery (accidentally stumbled upon something and then experimented further) or did they discover something accidentally through work on something else?** Accidentally through something else.
 * 4) **Did their contribution lead to a theory or a law? State name of the theory or law.** Found the Germ Theroy of disease from finding out about diseases were caused by micro-organisms.
