Notes from Hubert Goodrich's lecture. Trinkaus continues Periblast notes from page 8. Begins a new section on 'Gastrulation' with two diagrams of the 'embryonic shield', and a diagram and explanation of 'Kupffer's Vessicle'
Notes from Hubert Goodrich's lecture. Trinkaus has drawn four colored diagrams of 'Presumptive Regions': Trout, Fundulus, Dog fish, and Urodele
Notes from Hubert Goodrich's lecture. Trinkaus continues notes from page 5 on the movement of nuclear granules early in development, and then begins notes on 'Cleavage'
Notes from Oscar Schotte's lecture. Trinkaus begins notes on the 'Visible Polarity in the Echinoderm Egg' with two labeled diagrams and notes on the history of research on the topic.
Notes from Charles Packard's lecture. Trinkaus concludes his notes from Packard's morning lecture on the history of embryology (begin page 81) with some final thoughts from C.O. Whitman about epigenesis, heredity, and development, ending with the quote, "Facts without theory is chaos."
Notes from Oscar Schotte's lecture. Trinkaus continues notes from page 86 on the metamorphosis of echinoderms with general notes on rudimentary formation. Includes two diagrams (labeled 1 and 2).
Notes from Oscar Schotte's lecture. Trinkaus continues his notes from the previous page on parthenogeneis with some thoughts from F.R. Lillie, and then the beginning of an outline on the 'Processes after fertilization'
Notes from Oscar Schotte's lecture. Trinkaus draws 4 labeled diagrams of Chamber's work on fertilization in starfish

Notes from Viktor Hamburger's lecture. Trinkaus continues notes from page 57 and 58 on the copulation behavior of squid. He starts a new section on "Egg Laying"
Notes from Oscar Schotte's lecture. Trinkaus continues his notes on the echinoderm egg notes about the position of the first cleavage relative to the axis of the embryo. He offers results of various researcher's studies and concludes that "Vital staining method shows therefore that there is no coincidence of the 1st cleavage with the axis of the embryo"
