Summary
1.Schizosaccharomyces octosporus sporulates in both solid and liquid media. The morphological changes that precede sporulation show considerable variation. A pictographic summary is presented.
2. Rare instances of the dissolution of the septum separating two cells—as a prelude probably to conjugation—are illustrated.
3. The origin of cells within a cell during sporulation is a possible example of differentiation-in-time. If meiosis constitutes the stimulus for spore formation, the question whether the transformation of cells into gametes and the putting out of conjugating tubes are not themselves initiated by other crytological changes requires consideration.
