IV. SYSTEMATICAL SURVEY OF ATYPICAL EMBRYOSACS. 
As most authors have not paid much attention ‘to the dis- 
tribution of the protoplasm and to the arrangement of the nuclei 
during the early stages of embryosac development, this review 
necessarily {must be a critical one, including not only the}inter- 
pretation of the figures as given by the authors, but a discus- 
sion of the figures themselves as well. 
The common desintegration of an otherwise normal group of 
antipodals (fig. 8, laz,"la@, lay) as well as the secondary 
increase of the number’ of antipodals, are not included. For the 
rest the criticism reckons with all embryosacs, known to have 
more or less than the ordinary number of eight nuclei, and it 
thus covers the whole range of possibilities represented in fig. 4—8.
