(Thorns.) into the vulvae of supposedly sound heifers, and believed that he produced the disease. It is a notable fact that in Ostertag's experiments, while he believed he had trans- mitted the disease to cows and heifers by means of pure cultures, he failed to transmit it to sheep, go^ts, and swine, although they regularly suffer from it. It is not clear, however, just what he accomplished. Doubt is thrown upon.
