The coats of the vessel, at that part, adhered more in- timately to each other than in a natural state; but it was evident that the sac was formed by the dilated internal, middle, and external coats of the artery. Ia the aneurism which was situated immediately above the diaphragm the dilated coats of the aorta could ))e traced to some distance into the sac, the remainder of which was composed of the parts contained in the posterior mediastinum and the ver- tebrae. This aneurism was too large to be represented in this jdate, but that stage of the disease in which the dilated coats of the vessel have given way, and the surrounding parts form the remainder of the sac, is shown in the following figure. / Fig. 5. represents an aneurism of the thoracic aorta. A considerable portion of the sac is continuous with, and ap- pears to ]je formed by, the dilated coats of the artery. The part at which the coats of the vessel appear to terminate is seen near the middle of the sac, the remainder of which is composed of a portion of the lungs. The difference in the structure of the two parts of the sac was very evident, and indicated the line at which the dilated coats of the vessel seemed to terminate. Fig. 6. represents a portion of a popliteal artery, from the side of which a small sac arose.
