378 EXPLANATION OF PLATES 



Fig. 31. Right Femur, viewed from the pre-axial side, X 5. 



Fig. 32. Right Femur, viewed from the extensor side, X 5. 



Fig. 33. Right Femur, viewed from the flexor side, X 5. 



Fig. 34. Right Half of the Pelvic Girdle, viewed from the ventro-lateral side, X 5. 



Fig. 35. Right Half of the Pelvic Girdle, viewed from the mesio-dorsal side, X 5. 



Fig. 36. Tpsiloid Cartilage, ventral aspect, X 5. 



PLATE VI 



Fig. 37. Dissection of the Ventral Side of the Head. On the left side of the figure the 

 skin only has been removed, while on the right the superficial muscles (MM. inter- 

 mandibularis and interhyoideus) have also been cut away to show the deeper 

 structures, X4. 



Fig. 38. Dissection of the Ventral Side of the Head. On the left side of the figure all 

 but the deepest muscles have been removed, thus exposing the hyobranchial skele- 

 ton, while on the right side this skeleton has also been taken away to show the 

 structures on the mouth floor, X 4. 



PLATE VII 



Fig. 39. Right Radius, viewed from the extensor side, X 5. 



Fig. 40. Right Radius, viewed from the pre-axial side, X 5. 



Fig. 41. Right Radius, viewed from the flexor side, X 5. 



Fig. 42. Right Humerus, viewed from the post-axial side, X 5. 



Fig. 43. Superficial Extensor Muscles of the Shoulder and Fore-limb. Viewed from the 

 dorso-lateral aspect, X4. 



Fig. 44. Deeper Extensor Muscles of the Right Fore-arm and Hand, as revealed by re- 

 moving the M. extensor digitorum communis, X4. 



Fig. 45. Superficial Flexor Muscles of the Pectoral Region and Left Fore-limb, X 4. 



Fig. 46. Deeper Flexor Muscles of the Left Fore-arm and Hand, as revealed by removing 

 the M. flexor primordialis communis. The third and deepest layer of flexor muscles 

 cannot be seen, X 4. 



PLATE VIII 

 Fig. 47. Superficial Extensor Muscles of the Right Hind-limb, X4. 

 Fig. 48. Superficial Flexor Muscles of the Right Hind-limb, X 4. 

 Fig. 49. Deeper Flexor Muscles of the Right Hind-limb, the third and deepest stratum 

 of flexor muscles is not visible, X4. 



PLATE IX 

 Fig. 50. Sagittal Section of the Brain. The plexuses are diagrammatic, x8. 

 Fig. 51. Brain, dorsal view. The main veins and venous plexuses are also shown on 



the left, X8. 

 Fig. 52. Brain, ventral view. The main cerebral arteries are also shown, X 8. 

 Fig. 53. Af. levator bulbi seen from above, semi-diagrammatic after Luther. 



PLATE X 

 Fig. 54. Semi-diagrammatic Representation of the Cranial Nerves. The nerves which 

 normally lie on the ventral side of the mouth and pharynx are shown turned out to 

 the left. This has resulted in a somewhat disproportional elongation of the tenth 

 cranial and first spinal nerves. The relation of the nerves to the arterial arches is 

 also shown. The positions of the sense capsules are indicated by dotted lines.
