RECENT botanical investigations have proved, in more and 
more numerous cases, that in sexual fertilization a direct union 
of two sexually differentiated cells takes place, the product of 
which, as a fertilized ovicell, becomes developed into the germ 
of a new plant. At the same time it appeared that the most 
essential point in this union of the two sexual cells was the 
union of the nucleus of the male cell, which sometimes con- 
stitutes almost the entire mass of this male cell, with the 
nucleus of the female cell, in precisely the same way as also 
occurs in the fertilizing processes of animalst. Nevertheless 
several processes of fertilization not satisfactorily explained 
have hitherto stood in the way of a generalization of these
