3 Human embryo Klb. N.T. Fig. 3a and 3d; Text-fig 5a to 5n.	138 sections of 10 μ = 1.38 mm. Kroemer gives the following data: "The greatest length of the embryonic anlage from the anterior edge of the amnion of the head cap to the chorion end of the belly-stalk 1.95 mm., the length of the embryo without the belly-stalk from the head to the tail 1.8 mm., the greatest width of the yolk sack barely 1.2 mm., the width of the embryonic disk at the boundary between the amnion and yolk sack (measured in the head view) 0.9 mm. The measurements of the yolk sack were 1.1 mm, (height), 1.4 mm. (width), 1.5 mm. (length)."	The age is estimated by Born at from 10 to 14 days.	No dorsal bend. Head end bent down at right angles and cut by 24 sections of 10 μ.	Still indications of a neurenteric canal. Short primitive streak. CIoaca1 membrane.	5-6 pairs of primitive segments.	The chorda throughout is contained in the entoderm.	The medullary canal is everywhere wide open, but the brain portion is aire ady marked off from the cord and shows beginning segmentation.	Optic anlage not yet evident.				Primary pharyngeal membrane No oral sinus.		The 1st branchial pouch is formed but does not reach the ectoderm.		Heart ventral, but still paired. Paired aortse. 1st branchial arch artery. Aa. umbilicales. Yv. omphalo-mesentericae. Vessels on the yolk sack full of blood corpuscles.				No amniotic duct evident.	Allantoic duct	Obtained by laparotomy. Fixation: Mailer's fluid. Stain: alum carmine; paraffin. Sections: 10 n trans. Literature: Pfannenstiel in Handbuch der Geburtshilfe, published by Winckel, Wiesbaden 1903. — Kroemer, Wachsmodell eines jungen menschl. Embryo. Verhandl. d. Ges. f. Gynakologie, 1903. The wide pericardial cavity is not connected with the peripheral ccelom. The embryonic ccelom is being formed caudally. On the chorion the layer of Langhans cells and syncytium.
