septicæmiæ

The fact that pure cultures can almost always be obtained in this and kindred diseases—septicæmiæ— has been seen by the numerous gentlemen who have worked with me here and is also known to every investigator, for when we have mixed cultures do we not inoculate some very susceptible animal and thus get the pure culture of germ desired directly from the heart’s blood of such animal, and do we not do this to avoid the time and trouble of plate cultures ?
