1. Versuch. Gestalt der Samen.
1st trial: Seed shape.

The manuscript has a colon after Versuch, which we have reintroduced in the English translation, although Mendel did not correct this in his off-print.

1st trial = 1. Versuch Mendel retains the numbering of character pairs introduced in Section 3; see p. 8, s. 1ff. On the choice of “trial” over “experiment” here, see p. 3, s. 6.
