    SELECTIONS ON ANEURISM. PART I. SYMPTOMS, PATHOLOGY, AND CAUSES. GALEN.i When an artery is opened, tlie disease that occurs is called Second an aneurism. It happens in consequence of the skin in the neighbourhood of a wounded artery cicatrizing, whilst an ulcer remains in the vessel, which neither becomes agglutinated nor cicatrized, nor filled up with flesh. Diseases of this descrip- tion are known by their pulsating, and by their disappearing entirely when pressed upon; the contents of the tumour, which we have elsewhere shown to be a thin and bright blood mixed with much subtile spirit, warmer than that contained in the veins, passing back into the artery. If an aneurism be wounded, the blood is spouted out with so much violence that it can scarcely be arrested. In oedema the part yields to the finger when pressed upon, forming a pit; but there is no pulsation in that disease, and its colour is pale. (Edema likewise is much more widely diflFused than an aneurism, unless when any grumous blood is formed in the latter, giving rise to sphacelus. An aneurism is a dilatation or relaxation of a venous vessel, or a dispersion of the spirituous matter under the flesh, where it diffuses and distributes itself by jerks (per dissultationem.)^ ' Claudii Galeni Opera omnia, tom. viii, fol., Venet. ap.
