[Jan. 



twenty-four hours all the plants were growing under the same 

 conditions. At all times the conditions of temperature and 

 moisture were practically the same in both charged and nor-

 sults obtained by electrically charging the Air in a Case — Concluded. 



The experiment in Table 11. is similar to Experiment I., 

 except that the seeds were planted in rows 5 inches apart, 

 instead of 4, as in the preceding one. The cold weather in- 

 terfered with the development of the plants, and the experi- 

 ment was brought to a close earlier than was planned.
