Excerpt from Contributions to Embryology, Vol. 2: Nos. 2, 3, 4, 5, 6 These sacs and their contents were, immediately after their extrusion from the uterus, placed in 10 per cent formalin solution, followed by 70, 80, and 95 per cent alcohol. The sacs were then cut away, except Where the embryos were attached, and measurements and drawings of each embryo were made. Each was then cut transversely into serial sections 1071 thick, which were 'stained on the slides with hemalum followed by erythrosin. Both embryos, upon examination, appeared very similar in all features, so Embryo VI, which was somewhat the clearer of the two, was selected for the most thorough study, the results being supplemented by the findings in Embryo V.
