Note 44 — THE MODES OF ORIGIN OF LOWEST ORGANISMS.
Reading edition
When boiled solutions, containing mannite, with a little nitrate and phosphate of ammonia, were employed, they always remained sterile. Similar negative results followed the employment of ox-gall. Of three decoctions of beef with which M. Meunier experimented, the two stronger of them were found to contain swarms of Bacteria in about twelve days. Of three other flasks containing boiled urine, two also proved fertile.
