Opinions differ in regard to the autonomy and self-perpetuation of mitochondria. Observations on the living protozoon cell con- vinced Faure-Fremiet (1910) that the granules reproduce by spon- taneous division and this observation has been confirmed by others upon living and fixed material. Richardson and Horning (1931) in particular, after a slight modification of the pH of the milieu, obtained preparations of Oyalina showing practically every mito- chondrial granule in division (Fig. 38). In other cases, however,.
