In the tables, the first coluTnn at the left indicates the strength of 

 current to which each lot of seeds was subjected. At the top in each 

 table are given the normal or untreated plants while the following 

 numbers 1, 3, 5 etc. show the distance in centimeters to which the 

 secondary coil was removed from the primary coil u[)on the grad- 

 uated base, or in other words they represent the strength of current, 

 the strongest at 1 being about 10-1*2 volts, the weakest at 17 a small 

 fraction of a volt. In the following three columns is given the 

 number of seeds germinated in "24, 48 and 72 hours respectively. In 

 the fifth column the numbers show an average of the lengths in cen- 

 timeters* of all the radicles in each lot of twenty-five seeds at the 

 close of the experiment. The last column contains the gain per cent 

 by use of electricity. Following some of the tallies will be seen a 

 diagramatic representation of the results given in the column of the 

 average lengths of radicles. Each figure in the diagram represents 

 an average growth in the length of all the radicles in each lot of 

 seeds. 



Tables V. — VIII. are a repetition of the experiments in the first 

 four tables, the only variation being that in the place of the four 

 Leclanche cell battery a two Samson No. 1 cell battery was substi- 

 tuted and instead of treating the seed for only two minutes the treat- 

 ment was continued for five minutes.
