Notes from W.R. Duryee's lecture. Trinkaus continues his notes from page 33, and adds on "Organization of nucleus" in the Green frog (previously, Rana clamitans), including several idagrams. Notes include the triphasic nature of the nucleus and the effects of fixative additions
Notes from W.R. Duryee's lecture. Trinkaus finishes his notes from page 33-36 on the appearance, nature, and action of chromosomes and the effects of different fixatives. Trinkaus begins a new note section on "Significance to Embryology", and underlines a passage: "This is of course against the idea of cytoplasmic inheritance"
Notes from William Ballard's lecture. Trinkaus begins notes on "Coelenterate embryology" with information on "Medusa form"
Notes from Hubert Goodrich's lecture. Trinkaus continues his diagrams on the 'Development of the Circulatory System of Teleost' from page 25 and 26 with stages XIII and XIV and descriptions of stages VIII through XIV
Notes from Hubert Goodrich's lecture. Trinkaus draws four diagrams of gastrulation: Cyclostome (Weissenberg), Anuran (Vogt), Teleost (Pasteel), and Sauropsidian (Costello)
Notes from Hubert Goodrich's lecture. Trinkaus takes notes on the 'Nervous System' (with a fish brain) and the 'Intermediate Cell Mass'
Notes from Hubert Goodrich's lecture. Trinkaus makes notes on the 'Origin of the Cells of the Blood Vascular System', including the 'Monophyletic theory of origin of blood cells' and 'Polyphyletic theory', with special reference to Stockard on Fundulus. Stockard recognized three different types of cells (with diagram): '1. endothelial living cells of blood vessels'
