 1912, A Comparative Study of the Structure and Origin of the Yolk 

 Nucleus. Arcli. Zellforscli. Bd. 8 p. 663—716, 6 pis. [Real nuclei in 

 cytoplasm are pathological (degeneration of egg). Karyolymph acts as a 

 ferment in cel), producing Metaplasm. True yolk nucleus is a centrosphere 

 with aster and serves as center of assimilation and grovrth, can not be 

 formed de novo. Not to be compared with Infusorian macronucleus 

 nor with mitosome in sperm cells of Papilio.]
