The average variation between two different trials, 200 seed at a 
trial, the conditions being not exactly alike in temperature, but. 
deemed at the time as varying but shghtly, is as follows:— 
No. of trials. Average difference. 
1 year seed 8 32 
2 year seed 11 18 
3 year seed 3 17 
Average 22 
We thus note that the variation between duplicate trials, with 
mixed varieties of seed may exceed 17 per cent., and averaged in one 
case 5 per cent.; with apparent duplicates the variation between the 
trials may exceed 48 per cent., and in one case averaged over 22 per 
cent. 
Our next trial to report is when the temperatures were absolutely 
known in three out of five cases, and the other conditions identical.
