It is also equally plain how tin-occurrence of aneurism is favoured; by theproneness to ulceration; and by the impair-ment of elasticity, cohesion, and plastic , rupture of the internal coat, non-repair of the breach, on the contrary its exten-tension, are obviously rendered liable and degeneration may follow or accom-pany the state just described. Frequently,however, it is the concomitant and result of oldage. As the arcus senilis forms on the cornea,as the body bends, as the prostate enlarges, asthe teeth drop out, and the cartilages ossify, sothe arterial tubes are liable to become hard andnon-elastic, by deposit of earthy matter betweenthe internal and middle coats ; sometimes in gra-nules, more frequently in scaly patches, some-times in continuous masses.
