As regards the physiology of nutrition in the egg cells of 
Gymnosperms bnt little is to be fonnd in the literature, but the 
socalled „protein yacuoles“ and- protein granules lying in the 
cytoplasm of the egg, have attracted the attention of yarious anthors. 
Hofmeister 1 ) first called attention to the protein yacuoles 
nnder the name „Keimbläschen“. He took them for cells formed 
hy free cell formation and thought that from one of them the 
embryo arose. Schacht 2 ) howeyer recognised them as yacuoles 
and speaks of them in his text as „Scheinzellen (yacuolen)“ and 
says (p. 399) that these strnctures „die ich nicht für wahre Zellen, 
sondern für Yacuolen oder Scheinzellen halte“, haye not the natnre 
Hofmeister assigned to them. Strasburger 3 ) also thought that 
they had the natnre of yacuoles, and as they contained protein 
grains he spoke of them under the name „Eiweiss-Vacuolen“. 
Goroschankin 4 ) on the other liand says of these bodies that 
they „keine Yacuolen sind (wie Strasburger (sic) meint), sondern 
grosse Ähnlichkeit mit Zellkernen besitzen“. 5 )
