 compared. Proc. Assoc. Official Seed Analysts 1919: 04. 1919. — The results of 104 compara- 

 tive and simultaneous germination tests of crimson clover seed, made between folds of blotting

 in soil in the greenhouse was 42 per cent." — M. T. Munn.

 Sudan grass seeds. Proc. Assoc. Official Seed Analysts 1919: 58-04. 1919. — A brief account 

 of the results of comparative microchemical and permeability studies, also, gross chemical 

 analyses of the seeds of these two closely related grass plants are given. These studies were 

 made to determine whether there are any differences in their chemical nature, which might 

 serve as a basis for explaining their marked difference in dormancy, germinating and after- 

 ripening. — M. T. Munn.
