WEATHERWAX: GAMETOGENESIS IN ZEA MAys 89 
of cytological fact upon which recent experiments on endosperm 
heredity in maize have been based. 
I take opportunity here to express my obligations to Professor 
D. M. Mottier for the suggestion of this problem and for valuable 
assistance and criticism in connection with the study.
