This piece was taken off and the culture vessel placed in the sterilizer, an assistant holding the water bottle. The elongation piece was then put over the water bottle and while the experimenter grasped the bottle from above the assistant put the elongation piece into position again. The water bottle was now suspended by means of a copper wire tied around its.

Subse- quently the top was put on and sterilization allowed to take place. The arrangement of the culture is shown in Fig. 14. The seeds used in these experiments were first washed with, corrosive sublimate of a concentration of 1:1,000. This had to be done quite.
