    Notes: This report on the early human ilium is based on the Streeter collection, Carnegie Institution of Washington, Department of Embryology, Baltimore. The five phases in chondrogenesis, described by Streeter for the humerus ('49) and the horizons (Streeter, '42) are used in the description of the changes observed in the ilium. From horizon XV (7-8 mm, 30-32 days) to horizon XVIII (14-16 mm, 36-38 days) component cells of the ilium are mesoblasts. In horizon XIX (17-20 mm, 38-40 days) young cartilage cells have appeared. Both phase 1 and phase 2 cells appear in horizon XX (21-23 mm, 40-42 days), the former characterized mainly by the first appearance of intercellular material, the latter by their slender shape and arrangement in tiers. Phase 3 cartilage cells, cuboidal with many vacuoles, appear in horizon XXI (22-24 mm, 42-44 days). Increasing vacuolization of the cytoplasm of cells is noted throughout horizons XXII and XXIII until, in horizon XXIII (28-30 mm, 46-48 days) total disintegration of cells, a feature of phase 5, is evident. Thus the phases of cartilage differentiation described for the humerus are present also in the ilium.

    Notes: The common method of demonstrating cranial nerves and cerebral arteries to students during removal of the entire brain in the gross anatomical laboratory is unsatisfactory in that only the actual dissector is able to view clearly the structures at the base of the brain. Therefore, a method of hemispherectomy is described; it has the advantage that dural folds, cranial nerves, and cerebral vessels, are preserved in situ until the student has reviewed the anatomy of the cranial fossae and studied important relationships. It is, however, necessary to sacrifice the hemisphere first by taking horizontal slices down to the corpus callosum and then by removing the remainder piecemeal. The method, therefore, cannot be recommended as routine unless neuroanatomical material is available.

    Notes: This paper reports that extensive removal of bone from the superior and lateral aspects of the orbit is easy with the aid of an autopsy saw. When this is done and the lateral rectus muscle cut an excellent exposure of the orbital contents is gained.

    Notes: In seven human fetuses of C.R. lengths ranging from 38 mm to 100 mm primary ossification of the ilium has been described.In the 38 mm fetus the perichondrium at the caudal border of the ilium in the vicinity of the greater sciatic notch is intensely basophilic and contains osteoblasts. In another 38 mm fetus in the same area new bone is present.In the 50 mm fetus bone has spread cephalad over the internal and external surfaces of the ala of the ilium without invading the underlying cartilage.In the 58 mm fetus pores are present in the bone and through them osteoblasts and vascular elements are invading the disintegrated cartilage to form the primary marrow cavity.In the 66 mm fetus the primary marrow cavity has spread into the ala of the ilium.The whole process is similar to that seen in the primary ossification of the shaft of a typical long bone and follows the sequence described by Streeter ('49).

    Notes: This article describes a rapid exposure of the facial nerve by splitting the parotid gland along the faciovenous plane originally described by Patey and Ranger ('57).Scissors are thrust deep into the gland along the venous plane, and then opened to expose the facial nerve. This has been done in approximately 30 dissecting room subjects.

    Notes: By means of two sawcuts the middle ear can be exposed quickly. The first cut in a coronal plane through the suprameatal triangle usually bissects the tympanic antrum. After removal of the tegmen tympani and the incus, the second sawcut is made in an antero posterior direction; the blade of the saw descends into the gap left by the removal of the incus. Thus the middle ear is split with the tympanic membrane on one fragment and the medial wall of the middle ear on the other. This method has proved to be rapid and effective and superior to the traditional method of nibbling bone to expose the antrum and middle ear.
