Notes from Oscar Schotte's lecture. Trinkaus continues his notes on Runstrom's work from the previous page, then begins a section on Lindahl's egg constriction experiments (with diagram). Begins section on "Vegetalization" with information about normal development and the effects of different chemical compounds (with diagrams)
Notes from Oscar Schotte's lecture. Trinkaus continues his notes on vegetalization with information about the effects of different chemical compounds on development (includes diagram). Trinkaus begins new section, "Animalization" with several diagrams and information on different chemical compounds
Notes from Oscar Schotte's lecture. Trinkaus continues his notes on Lindahl's experiments, and writes a lot about the effects of different chemicals on different stages of development
Notes from Oscar Schotte's lecture. Trinkaus continues his notes from the previous page on Horstadius, with information on the methods he used to study animal/vegetal poles and the possible significance of the work. Begins an outline "1. Isolation of whole animal half of egg" with diagrams.
Notes from Oscar Schotte's lecture. Trinkaus continues his notes from the previous page on recombination experiments for the different cell stages (with diagrams). Trinkaus creates an illustrated chart of Horstadius' different recombination experiments
