THE human embryo Pfannenstiel- III. was placed at the disposal of Pro- fessor Keibel, for publication in his Normentafel zur Entwickelu4qgs- geschichtedes Menschen,by Professor Pfannenstiel of Griefswald. Inthe NormentafeltheembryoisNo.6(fig.Vr.andVv.) ProfessorKeibel kindly afforded me the opportunity of studying this embryo in the Anatomical Institute in Freiburg, and at his suggestion I undertook to reconstruct models of the embryo according toBorn's method. The work of modelling was begun in the Anatomical Institute in Freiburg, and completed in the Anatomy Department, Aberdeen University.

The embryo Pfannenstiel I. was obtained at an operation, and as measured through the amnion had a length of 2-6mm. The embryo was fixed in formalin-Muller's fluid, stained in paracarmine, and sectioned at a thickness of 10MA. Histologically the embryo is in an excellent state of preservation. A model of the whole embryo has been reconstructed at an enlargement of 100. A separate model of the nervous and alimentary systems has also been made, and three models of pharynx, heart with its blood-vessels, and septum transversum at an enlargement of 150.
