The manuscript repeats die Hälfte in the third row of the table. It also orginally had hohe (“high”) which was then replaced by lange (“long”).

presupposition = Voraussetzung Bateson has “theory”, Sherwood “assumption”. Mendel is referring to p. 28, s. 1, which in turn is based on the “assumption” made at the beginning of the section (see p. 24, s. 8). While the preceding experiment tested the latter assumption (“that as many different kinds of germ cells (germ vesicles) are formed in the ovary, and as many kinds of pollen cells in the anthers, as constant combination forms are possible”) directly, this experiment tests it indirectly, by testing a prediction derived from it. At the same time Mendel demonstrates his skill in constructing hybrid forms at will. As in the previous experiment, the crucial point of these experiments is that artificial pollinations are carried out where spontanous cross fertilisation took place in the experiments reported in previous sections.

one half = die Hälfte The determinate article reflects the fact that this ratio is formulated across the whole population, irrespective of which other characters the plants in question exhibit.

Members = Glieder See p. 20, s. 12. The numerals indicate the position of the “members” in the preceding formula. “1⋅3”, for example, points to AaBb and Aab, the two members of the formula that contain Aa, but differ in their genetic constitution with respect to the other trait (Bb and b respectively).

flowers = Blüthe Blüthe is obviously a misprint for the plural form “Blüthen”. The manuscript does have the plural (Blüthen).
