Marek has also obtained 1.468 grams of fat from lOO large 

 grains of peas while only 0.524 gram was contained in small ones.

Thus, the results of investigators all go to show that large 

 and consequently heavy seeds are rich in oil. My results, as 

 already mentioned, also lead to the same conclusion, and they also 

 show that with rape, i^lump grains of regular size always have a 

 medium specific gravity. Marek attributes the richness in oil of 

 large seeds to the transformation of starch into oil in the process of 

 ripening since large seeds are always fully rii:)ened ones, while 

 small ones are more or less immature. This hypothesis, however, 

 seems to me to need further investigation.
