fest themselves later in its sound neighbors. In these decayed grapes I find alcohol. I find it also, at least so I believe, in the dry grapes, and I see there no cells of yeast. Thence, the idea of my diastase. It may very well be that this secretion of diastase takes place only once, and that I came at a fortunate moment, while you were too early or too late, but that will not hinder us from remaining good friends. "Note furthermore," Bernard might have continued if he had been able to plead his own cause, or if he had had an advocate, "that my conception is in accord with some of the experiments which you cite in support of yours. MM. Lechartier and Bellamy before you have seen fruits, put in closed flasks in the presence of air, begin by absorbing oxygen, then give off carbonic acid, and, furthermore, produce alcohol by an interior fermentation accomplished without the aid of any yeast cell. It is one of the experiments which you cite in support of your ideas of life without air. I consider it as a score for me, and I say that the results of MM. Lechartier and Bellamy have to do only with the decay of fruits in confined atmospheres. But if they were rotted in contact with the air it would be the same, as my results with grapes testify, and as, I hope, the experiments which I intend to make on apples will also testify." "But," responded Pasteur, "you who have such a good memory for the results of MM. Lechartier and Bellamy who, moreover, are in accord with me, how is it that you have forgotten my experiments in which, instead of waiting until they shall have consumed the oxygen of the air with which they are in contact, I plunge the fruits immediately into carbonic acid, and see the formation of alcohol begin there immediately. Can it be a question of decay in this quick experiment -211- |
