Here, the most difficult and the most responsible duties of the surgeon are occasionally called into instant requisition, without time for study or preparation of any kind. The importance of the arterial system in the economy, its liability both to injury and to disease, the depth and complicated relations of the individual vessels to other and contiguous structures, all attach to it the highest degree of interest to the operating surgeon. We are indebted to Haller for the first minute descrip-structure of tion of the structure of these vessels. From him we arteries. learn that an artery is composed of three coats, the external of which is cellular, filamentous, and elastic. To this coat the artery mainly owes its firmness, and its patency when cut asunder. The middle coat, which is fibrous, has been the subject of much investigation since the period of Haller. It is now deemed to be composed of muscular fibre, arranged circularly around the vessel, but intermixed with elastic tissue, the proportion of the muscular and the elastic tissue varying as the arteries reach the remote parts of the body, in which the latter is gradually reduced in quantity, and gives place to the contractile action of a muscular coat.
