In another experiment the wheat plants grew in solutions of 
glycocoll and methyl glycocoll, side by side at the same time, from 
February 22 to March 4. In this test only 11 different nutrient 
solutions were employed. One set of 11 cultures was used as a 
control; to each culture of the second set of 11 cultures 50 ppm. of 
glycocoll was added, and to the third set methyl glycocoll in the 
same amounts was added. The result of this test was very much 
the same as observed in the preceding experiments. The glycocoll 
produced increased growth in those solutions which contained no
