    >1 I Artery, by the ligamentous remains of the Ductus Arteriosus ; the Par Vagum of the left side crosses it, and its recurrent branch hooks under it: from this part of the arch arise the three great vessels to supply the Head and superior extremities. The third, or descending portion of the arch, is continued from the last, downwards, and backwards, between the Vertebrae and left lung, and ends at the left side of the body of the third Dorsal Vertebra ; this bone, in old subjects, is often indented on its left side, the pressure of the artery causing its absorption ; the CEsophagus and Thoracic Duct lie on the right side, and somewhat in front of this portion of the arch. The Aorta then descends along the left side of the Vertebral column, under the name of the Tho- racic Aorta, the description of which shall be re- sumed after that of the branches of the arch. There is no exact distinction between the termination of the arch and the commencement of the Thoracic Aorta; nor, as Dr. Barclay observes, does the one deserve the name of Thoracic more than the other. Before the student traces any of the branches of the Aorta, he should pay particular attention to the different re- lations its arch bears to several surrounding parts, and consider the effects that aneurism of this vessel is likely to produce. He should observe the curve which the Aorta makes in this course, how it first advances near to the Sternum, and then recedes to the Vertebrae ; thus the aneurismal tumour may incline forwards, and cause the absorption of the Sternum and cartilages of the second and third Ribs on the right side, or may press backwards.
