Garrison & Morton 2488:
Koch greatly improved staining methods; he laid the foundations of the technical procedures employed to-day. In the above paper he described his methods of making films of bacteria on cover slips and fixing them by gentle heat; he also gave details of his method of photographing bacteria. In some of his plates the cilia are clearly perceptible.
