    The analogy between the extra-vascular animal and the vegetable tissues is ma- nifest. The application of the above-named law to the study of Surgery, in reference to the causes of the prolongation of vessels into the extra-vascular tissues^ and to the measures to be adopted for the prevention and cure of those diseases which are de- pendent thereon; and to Pathology, in the investigation of the nature of morbid structures, particularly of those classes which contain no vessels,—will, I feel certain, be productive of interest and great advantage. In conclusion, I have to thank my estimable friend Mr. Edward Dickinson, for the many acts of disinterested kindness he has conferred upon me, which have tended much to supply matter to this paper. Every one will see how much 1 owe to the skill of Mrs. Holmes. My brother, Mr. George Toynbee, by the valuable assistance he has afforded me in editing and arranging this paper, has added another to the many deep obligations which I owe him. For his good counsel, from the time I entered the profession to the present day, I am more indebted than words can express. Explanation of the Plates. PLATE XIII. Fig. 1. The anterior surface of the inferior extremity of the femur of a human foetus of about four or five months. It has been macerated for some time in water, and the cartilage of the epiphysis is somewhat transparent, so that a canal for the epiphysal blood-vessels is seen in its substance. A. The orifice of a canal. B. The synovial surface of the cartilage. Fig. 2. A section of a similar extremity of the femur of a human foetus somewhat older. A. The osseous cylinder of the femur. B. The cartilaginous epiphysis. C. Canals for the blood-vessels. D. The synovial surface of the cartilage. Fig. 3. The blood-vessels which are contained in the canals of the epiphysis. A. The artery. B. The dilatations with which the arteries and veins are continuous. C. The veins. Fig. 4. The blood-vessels contained in a longer epiphysal canal. A. The artery. B. The intermediate dilatation. C. The vein. 2 c 2
