    forming a complete septum between the thorax and abdo- men, (b) great development of spleen, (c) development of great omentum. Great omental development is prim- arily correlated to great splenic development. With the assumption of the erect position in man, the great omen- tum is a factor in supporting the transverse colon. A human omentum that was free of transverse colon would be one liable to torsion, and this would be more likely on the left than on the right side. In these studies variability is shown as regards the position of entrance of bile ducts relative to the pyloric sphincter and duodeno-intestinal junction, and also in the relation of the pancreatic to the Idle duct; so that prob- lems referring to digestive function are raised. In a typical section of the human pancreas the areas of Lan- gerhans may be difficult to define; but in histological sections of the pancreas of, e.g., the Wombat or Tas- manian Devil, numerous areas are to be met with. Many other functional problems might be mentioned, but these few examples are cited to show what a rich field is open to the medical research scholar. In conclusion, the writer wishes to thank the Presi- dent and Council of the Royal College of Surgeons of England, and also Professor Arthur Keith, for facilities accorded him while working in the laboratories of the Hunterian Museum; Professor Sir Baldwin Spencer and Mr. Kershaw for the privilege of conducting researches at the National Museum in Melbourne; the Editor of the ‘‘Journal of Anatomy” for permission to reprint his article on the Spleen in Yol. LI. of that journal; his cousin, Major Charles Mackay, for valuable help in the preparation of the dissections; and also Mr. Finerty, of London, and Miss Esther Paterson and Mr. Victor Cobb, of Melbourne, for the excellent illustrations.
