On wounds of arteries, and the means adopted by nature and art for the suppression of hemorrhage; their structure; ancient three coats separated into six-1, the epithelial; 2, fenestrated; 8, muscular; 4, elastic; 5, elastic and areolar combined; 6, areolar. Nature of epithelium; divided into three kinds--tesselated, cylindrical, and spheroidal. Structure of epithelial (1) and of fenestrated coat (2); structure of muscular (3) and elastic coat (4); structure of elastic and areolar coats (5 and 6). Chemical composition, protein. Voluntary and involuntary muscular fibers; difference between them. Muscular fibers in arteries involuntary. White inelastic and elastic yellow fibers in outer coat. Blood-vessels of arteries; nerves of. Production of cells, nuclei, and nucleoli. Cyto-blastema or formative substance. Collateral circulation of two kinds--by direct, large, communicating arteries, and by the capillary vessels, both being incapable of supporting life in the lower extremity after the receipt of a sudden injury to the main trunk in the thigh. pp. 176-187 LECTURE X. Proper treatment of wounded arteries due to the Peninsular war; Hunterian theory inapplicable; opposing theory of Mr. Guthrie; means supposed to be adopted by nature for the suppression of bleeding from large arteries from the time of Celsus to 1811 disputed; their true nature shown; important distinction drawn between the processes adopted with the upper and lower ends of a divided artery; cases illustrative of the facts stated; application of a small ligature; consequent processes; opinions formerly entertained, erroneous; internal coagulum not absolutely necessary; artery does not always contract up to its next collateral branch, nor is it necessary; important case in proof; ligatures should be small, round, and strong; undue interference to be avoided. pp. 187-208 LECTURE XI. Appearance of the femoral artery when torn across high up; illustrative cases. A small puncture; illustrative cases. An artery of the size of the brachial cut to a fourth of its circumference; when completely divided; when wounded at some depth from the surface; course to be pursued; illustrative case. No operation to be done on a wounded artery unless it bleed; cases: John Wilson, Don Bernardino Garcia Alvarez, and Captain Seton. pp. 208-226 LECTURE XII. Mortification local and dry in the first instance. Case deserving of great attention. Amputation not always to be had recourse to in such cases; the case of Cook demonstrative on this point. General treatment in such cases. Wounds of the arteries of the leg. Case of H. Vigarelie decisive of the principle and the practice to be pursued. Remarks on the bleeding from great arteries. The surgery of the Peninsular war in advance of the surgery of civil life. Case of suppurating aneurism of the axillary artery; bursting after ligature of the subclavian; wounds of the radial in the hand. pp. 226-240 LECTURE XIII.
