The disagreements on the question whether the nucleus of yeast is an organelle unrelated to the vacuole or whether it is the vacoule itself (Pictographic Summary I, 1844-1956) is only a corollary to the limitations of fixation and staining procedures carried out on cells in which the former was invisible. A reconciliation is possible if investigations are confined to cells in which both the organelles are visible. The extra-vacuolar nucleus has a conventional vesicular structure with a nuclear membrane, chromocenters and nucleolar equivalents. The vacuole, which has a limiting membrane in older cells, is Feulgen negative and segregates neutral red in living cells. It is therefore a cytoplasmic inclusion. A strict comparison of living with stained preparations is presented in Pictographic Summary II, 1956.
