34 His assistants brought the news to Pasteur-all the unvaccinated sheep were ill, but so were several which had been vaccinated. Pasteur, less calm than he had appeared in public, lost his temper and began shouting at his assistants, saying they had made a mess of the experiment and a fool of him. He spent a sleepless night working himself up into a state, but the next day brought better news. The vaccinated animals were recovering. He returned to Pouilly Ie Fort on June 2nd, the date set for judging the experiment. As he walked towards the farm the crowd began to applaud, and as he got closer, to cheer. Twenty-two of the unvaccinated sheep lay dead, and a further two died as the spectators looked on. Meanwhile, every single one of the vaccinated animals was grazing contentedly, in a state of perfect health. Pasteur was triumphant, and soon all Europe knew about his success.
A rabid dog One final success was to crown Pasteur's achievements. The year before the public trial of the anthrax vaccine, Pasteur had begun studying rabies. Although it was a relatively rare disease people were very frightened of it. A dog suffering from rabies would go mad, foaming at the mouth and ferociously biting people. Someone who was bitten might not develop the disease, but if they did they would die a horrible agonizing death. The only known way of preventing the disease after biting was immediately to cauterize the wound-to burn it with hot metal. This was terribly painful, and it did not always work. In order to study rabies, Pasteur and his assistants had to collect saliva from mad dogs. An accident at any stage of handling the material they were investigating could have resulted in a terrible death. 35
