Secondly three cases of two micropylar eggs are reported 
(Srraspurcer 1878, Fiscarr 1880, Murseck 1902). In itself a 
secondary increase in the number of micropylar nuclei is not 
in opposition to our views. In more recent literature however 
no such cases are met with. Therefore these records were not 
inserted in our general survey, as they can only be accepted 
under reserve of further confirmation. Especially since these 
cases do not represent normal conditions, but anomalies. FiscHEr 
himself even doubts the correctness of his observation, the only 
indication being one section ,dessen Tauglichkeit durch den 
Schnitt leider herabgesetzt worden ist.« 
Thirdly in a few publications a synergid is mentioned as having 
assumed the function of an egg or of an upper polar nucleus. 
Almost all of these studies are dated long before triple fusion 
was known. The only exceptions are Pace on Cypripedium and 
Kusano on Gastrodia, but their figures probably have been mis- 
interpreted, as we have already discussed (p. 49—52, 53—5)). 
Lastly we have to deal with four cases in which there should 
be an egg of chalazal origin (CHamBertain 1895, Tretsaxow 1898, 
Pacz 1907 and Kusano 1915). There is no need to repeat again 
whath has been said in our discussion on Cypripedium (Pacg) 
and on Gastrodia (Kusano). As to the other two: Marie Opprr- 
MANN (1904), when reinvestigating the Aster embryosac, says 
that “there was nothing to indicate the presence of an antipodal 
egg*. She too noticed that often one of the antipodals becomes 
larger than the other two, “but in no instance was I able to 
find in this lowest cell an antipodal oosphere as described by 
CuamBeriain (1895)*. The embryosac of Allium odorum (TRETJA- 
Kow, 1895) is of the normal 8-nucleate type. The author speaks 
of embryo formation “zuweilen sogar aus allen drei Antipoden, 
und zwar ohne Befruchtung.* This development begins “erst 
nach der Befruchtung der Hizelle*. This really seems to be 
nothing else but a secondary increase of antipodal nuclei, quite 
common now. 
We seem justified in finishing this study by stating that all 
literature on the Angiosperm embryosac confirms our views, 
the only exceptions being: a few publications of too old a date
