    left side of the spine. My son made a similar experiment upon a ram, and passed a ligature around the artery, opposite to the third lumbar vertebra. The blood still continued to flow to the extremities, for there was no diminution of heat of the hinder limbs, and the animal retained the feeling and power of moving them, so that none of the nerves had been included in the ligature. It may be added, that, after the death of the animal, there was no appearance of peritonaeal inflammation. INFERENCES. From what has been above stated regarding obstruction of the abdominal aorta, it follows ; 1st, That an aneurism of the abdominal aorta is sometimes cured, by an effort of nature, by an obstruction of that vessel above the seat of the disease. 2d, That an aneurism of the abdominal aorta, accompanied by an obstruction of that vessel, is not invariably characterized during life by any one pathognomonic symptom, even when there is reason to conclude that the disease had been of some duration. 3d, That an aneurism of the abdominal aorta does not prove invariably fatal, as that vessel has been sometimes completely obstructed by a plug of coagulable lymph; notwithstanding which the blood still flowed to the lower parts of the body. 4th, That a ligature may be passed around the abdominal aorta, with the prospect of saving life, when the aneurism is seated in that part of the aorta which intervenes between the origin of the superior and inferior mesenteric arteries, and also when the aneurism occurs at the division of the aorta into the great iliac arteries. 5th, That, during the passing a ligature around the abdominal aorta, great caution is requisite, lest a part of the hypogastric plexus of the nerves which surrounds two thirds of that vessel, be included in it, which would undoubtedly bring on an incurable
