Notes from Viktor Hamburger's lecture. Trinkaus continues his notes on the process of ejaculation, including a diagram
Notes from Oscar Schotte's lecture. Trinkaus continues his notes on the the structure of the echinoderm egg, with two diagrams, then begins notes on insemination in starfish with a diagram
Notes from Oscar Schotte's lecture. Trinkaus continues his notes from the previous page on recombination experiments for the different cell stages (with diagrams)
Notes from Oscar Schotte's lecture. Trinkaus continues the outline that he started on the previous page with a diagram of the pluteus, "Isolation of Vegatative half", and "In third series he raised both halves"
Notes from Oscar Schotte's lecture. Trinkaus continues notes from the previous page on Runstrom's double gradient theory. Then begins notes on Horstadius and recombination experiments for the different cell stages (with diagrams)
Notes from Oscar Schotte's lecture. Trinkaus concludes the outline that he started on page 100 with notes on "1. Equatorial eggs" (with diagrams) and "2. Subequatorial eggs". Trinkaus then begins notes on Runstrom's "Double Gradient Theory" (with a diagram)

Notes from Oscar Schotte's lecture on "Echinoderm Embryology". Trinkaus takes notes on the phylogeny of echinoderms, and begins notes on echinoderm eggs.
Notes from Oscar Schotte's lecture. Trinkaus continues his notes on general information about the eggs of echinoderms, then begins notes on the history of research on echinoderms
Notes from Oscar Schotte's lecture. Trinkaus continues his notes on the echinoderm egg, with diagrams and discussion of Jenkinson (1911) study of sea urchin egg formation. Two diagrams show the egg attached to the wall of the ovary and the structure of the egg.
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
